We arrived near the port of entry of the enemy country! We approached slowly. Our crew observes the monitors that are showing the images coming from the satellite. They want to find a security hole so that they can penetrate into enemy territory.

I, Fernando, and Chin-Mae we are standing in the hallway watching the aerial image of the harbor where we will go. We're watching the monitor the orders of the commander Severus to the entire team of boat control invisible, which appear written. The system, similar to the "Close caption*" enables information spoken in secret headquarters in Brasilia, written and appear in real time inside the boat.

- Lieutenant Julius! (official responsible for arms control boat). Be prepared for an attack if something goes wrong!
- Yes, sir! (Julius responds to higher).
- Major! (speaking to the commander Severus Margaret, pilot of the vessel). From now on I want you to always navigate smoothly and completely invisible. We can not and do not want to be tracked by our enemies. Use only the central thrust of our boat for us not to leave a trail behind us.
- Yes, sir! (she says the head of the mission).
- Soldier John! (military responsible for controlling external surveillance cameras). Be very careful! We're going into the enemy zone and any failure monitoring could jeopardize our safety. Do not miss any detail. When we get closer, I want you to send an artificial insect to nearby enemy soldiers that port. Let's hear it talk.
- I'm ready sir! You can count on me! (John the soldier responds confident).
- Ambassador Chin-Mae! We need your help to translate all that the North Korean military speak for us.
- Certainly, Commander! (The ambassador replied, speaking very softly to the commander. It is next to me in the hallway of the vessel).
- Soldier Ricardo! (Accompanying military radar signals invisible boat and it controls satellite surveillance). We're in a war zone. We have allies and enemies and they do not know of our existence here with them. I want you to watch them all carefully. We can not run into anyone. Also look for signs of submarines friends and enemies. We need to stay away from them. We run a big risk of being mistaken as an invisible enemy! Our mission is lonely for us we can not tell anyone where we are.
- Yes, sir! (Ricardo responds). Regarding the submarines will be very difficult to detect if they are submerged, sir! I advise we navigate in shallow water, avoiding them like this! We can also sail very close to the North Korean port because there is no vessel together and in this case we would have also crossed the enemy line of warships!
- Very good idea, soldier! (Commander Severus responds happy). Major! Approach the port! Let us look more closely at the drive location. We need to find a way to get past them and we penetrate into enemy territory.

The Major Margaret is piloting the boat invisible which is very close to the harbor enemy! By satellite images, zoom in for all of us, we realize the presence of several North Korean soldiers armed with machine guns stationed on concrete structures, while a cargo ship enters the port slowly narrow.

The pass door is closed until everything on the vessel inspected. While it is anchored there, the soldiers shoot eastern waters directly in front and rear of the ship.

Ambassador Chin-Mae looks at me and she asks, speaking very softly:

- Why are the soldiers shooting into the water? That makes no sense!!

I look back at her, but I can not tell you what they are looking for our boat invisible. In Brasilia, the secret base of operations of naval ship invisible, the commander Severus's watching with concern! He looks forward to his subordinates with an expression of dismay. Our commander knows that the enemy is firing at random, in those places, waiting there to detect the presence of our boat unseen and destroy us with a heavier armament afterwards.

- Well! Looks like we will not be able to enter the way we hoped, through the enemy port (the commander Severus comment). They are waiting for us and they are meticulous so they are not surprised. We're out of options at this point...! We can not fly where our rockets are, because we have no fuel, and also because we would be detected if we did it...! We also can not go sailing because they would hit us with their guns...! We can not use the hovercraft system not to stand up too much water... I want new options, gentlemen! We need to go into enemy territory without being detected we are! Only in this way we could ensure the success of the mission to which we are called!

No one speaks! The silence of all indicates that we are no chance at the moment to carry out the plan to destroy the enemy tower transmission. The satellite images were all left to us, as we all seek to find a way to us to solve this issue. But this time... something totally unexpected happens...! The massive exit door is now open and offers a narrow passage in the entry for the stealthy enemy territory. But the commander Severus suspects such ease.

What is happening? (Severus asks, talking aloud to himself). Why are they so carefully for them not to be surprised... and then they will open a ticket so inviting...?
- It seems to be a trap, sir! (Major Margaret declares).
- Can we launch artificial insect there, soldier John? (commander asks).
- Not yet, sir! (John replies). We're a bit far for that!
- Major Margaret! Browse toward that narrow! (commander orders).
- But, sir! They may explode our boat! (Margarida, the pilot states concerned).
- We'll take our chances, Major! (commander decrees). We do not have a better option and nothing yet indicates that the enemy could detect us here. We also do not know how long this passage will open. Accelerate as fast as possible without we leave a trail in the water! We will enter this war territory! Corporals Everardo and Sabino, direct to your battle stations! Stand by for you to command soldiers spiders-if this is necessary...

A major Margarida, even with doubts, she obeys the orders of his boss and she maneuvers the boat Brazilian invisible to the harbor entrance. Sabino and Everardo, who hardly leave more of their maintenance room, they put the virtual reality goggles and he holds the joystick that controls his soldiers-spiders!

- Soldiers-spiders? What are they? (Chin-Mae asks, speaking softly to me).

It's getting increasingly difficult for me to continue to hide the Brazilian military secrets. She knows I will not say anything about these things, but she keeps asking about it! This time, I do not even look in the direction of the ambassador so I do not have to give a new excuse on the issue. My eyes are glazed on the images and they show everything around us.

The North Korean side awaits a naval vessel in the waters of the river estuary and the countryside! Once the exit gate is completely open, they receive orders via radio to an army admiral oriental:

- Warship secret! The gates are open for his departure. Rapidly between the port and perform their task in silence!
- Yes, sir! (The commanding officer of the ship responds eastern). We will accelerate ahead! Now! (The leader shouts to his crew).

The boat invisible Brazilian is already inside the harbor. The images from the cameras around the boat show North Korean military with their guns pointed at several places. They watch the horizon marine and fluvial! But none of them something is seen.
Our entire crew is on alert when the ambassador asks me again:

- How are we here inside this port and any North Korean military sees us? This is impossible!

Again I look at her and I say nothing! Just raise my eyebrows and I press my lips a clear expression of doubt about it! But of course this is a lie! I know the truth, but I can not reveal it to Chin-Mae. We quickly left the inner harbor, where a strong, continuous and dragged side impact happens in our boat, playing the ambassador on my arms! Our bodies are thrown against the inner wall of the hallway where we are. The vessel invisible and it leans slightly changes direction when entering the interior of the Taedong River!

- Are you okay? (I, Fernando, inquire her).

The beautiful face of that oriental woman was glued to my face for a few seconds. I felt the heat of her gorgeous body! I also felt cold hands, almost cold, when she held my waist for her to compose herself again standing before me. The concern of this woman, the face of danger we were living was clear! Our eyes met again closely! I felt the panting with fear! I wanted to kiss her on the mouth again at the moment, but I restrained myself! We have a mission and this may come to a screeching halt at any time! I felt that perhaps we all might die in the next few seconds! My only desire was to hold her, and I wanted to protect her from a dangerous situation! That's when she responded to my previous question, which I had almost forgotten that I had done:

- Yes, I'm fine...! But what was that...? In which we hit at all...? (Chin-Mae asks).
- I do not know! (I say stunned).
- In which we hit, pilot? Was in the harbor? We align the wrong boat?

In Brasilia, the secret base of the movable floor of the boat, where the military are, is also shifted heavily, swinging chairs all in place in line to the boat invisible true in Korean West Sea. The commander Severus inquires about the incident:

- What is happening here? As we hit? There was nothing in front of us!!
- The outer wall leds our vessel may have been damaged with this impact! (artificial intelligence invisible to the crew of the boat states).
- Leds? There are LEDs on the hull of this vessel? (Chin-Mae asks, now even without it looking at me because I say anything about what she asks).

Inside the North Korean vessel, which
had just hit our ship invisible, the
eastern commander also inquires about
the event:

- No, sir! We have not even entered
the harbor! (your pilot states).

The North Korean commander thinks for
a few seconds... and he says what he
believes to have happened:

- We hit the boat invisible Brazilian!!
They just penetrate our country!

On the bridge of our ship to major
Brazilian Margaret pronounced the
commander about the fact:

- It's a trap, sir! (a Major Margaret
screams, showing concern). We're
being attacked! We will fight back
before it's too late!

In an unexpected act for all of us, Chin-Mae, that just as I had read the words of the commander Major, she also decides to scream your opinion on the subject:

- We have to complete our mission discreetly, even against the North Koreans invisible boat!

It sounded like a bomb for all of us! As we could read the conversations of the crew, they can also hear us when she and I talked! After a few seconds of silence, artificial intelligence, with typical female voice and gentle commands Chin-Mae:

- Ambassador! Approach the cabin. The commander Severus want to talk to you!

Chin-Mae looks into my eyes, due to the wide statement of information so important that she had never said before! The ambassador is recomposed and she walks slowly and decisively toward the room of avatars. I still in the running and she could hear the captain shouting some more orders to the crew of our boat. In Brasilia, in secret naval base, the climate warms... because this time we spent effectively to participate in the war against Asian and just a boat invisible enemy! She and I are in the hallway, and we could hear the captain shouting some more orders to the crew of our boat. In Brasilia, in secret naval base, the climate warms... because this time we spent effectively to participate in the war against Asian and just a boat invisible enemy!

- Major! Evasive maneuvers! (Commander Severus orders). Set a course for irregular interior of North Korea! We do not want to be hit by another boat invisible. Soldier Ricardo! (Responsible for radar signals and thermal cameras and normal Brazilian satellite). Engage our radar! I wonder where is our invisible enemy! Soldier John! (Responsible for external cameras of the vessel and aerial cameras). Send an artificial insect invisible to we check the potential damage caused to the outer surface of our boat!
- I'm sorry, sir! The radar detects nothing here in River North Korean! There is no boat nearby! (Ricardo responds).
- Damn! He is also Stealth! (Commander Severus states concerned). Soldier John! Lance four artificial insects. Use them to detect, through laser GPS location, the actual position of our invisible enemy. Do insects fly at a safe height and track the whole river behind us. We have to find our invisible enemy here and now and mark it as a target, because when we return to the sea this task will be much harder. Lieutenant Julius! (Responsible for weapons). After identifying our enemy, schedule automatic three shots directly below the point of the first shot that we give! I want all the extra shots along the surface of the river! We will hull them and slow them or sink them once and for all!
- Yes, sir! (Julius responds).

Inside the boat unseen North Korean leader oriental crew also gives further orders:

- Lieutenant! Make a turn one hundred and eighty degrees! Accelerate to the interior of our Taedong River. Keep our discretion and invisibility. We will pursue the invisible boat Brazilian...!
- How they got here so quickly...? (Asks the commander eastern, talking loudly to himself).

- Perhaps, sir, they have more than one vessel invisible and they are reportedly probing in here for some time! (its immediate answers in charge).

- I do not believe it! Our spies have not confirmed such a thing! But how could they come here so quickly? They should have resources on board that we do not know! We must be vigilant! It will not be easy to find them! But soon they will fall into our trap and this will be the end of them! We'll sail slowly towards the source of the river. Trigger our radar location.

- I'm sorry, sir! (responsible for the system of the North Korean boat informs). The radar indicates that there is nothing in the coming miles away!

- Damn! Their boat is Stealth! Trigger the radar underwater! I want to know what are the marine engines operating at the moment here in the Taedong River. We'll find them this way! There is no hiding this noise under water!

- Sir! I detected the movement of an electric motor by little more than five hundred meters away toward the river mouth. He is fifteen degrees below us. No...! Correcting...! It is moving, sir! 10�... 5�... 0�... 5�... 10�...! He stabilized at 10� now six hundred meters away, sir!

- So it is moving zigzag! Let's chase them and hit them. Prepare to fire! Releasing attack only under my command! Let's get closer to ensure the crosshairs.

- Sir! I must remind you that our supreme leader ordered him to be warned if the boat invisible Brazilian penetrate the Taedong River! (the immediate declares).

- No! Yet! We'll catch him before! (commander informs).
- But, sir! Was an explicit order!

Nervous, the commander turns to face her and he immediately tells him closely and quietly, but angrily:

- If we now inform him... two terrible things will happen: He could start a nuclear war... and you know that he is well capable of it! The international response would be a bombing... so devastating... would cause the complete destruction of our country, our people and our families...! And even if our supreme leader not start a new Asian holocaust... we will all be called up after his presence... and our punishment will be death for this failure! So... immediately... we will destroy that ship invisible before they complete their mission and inform then the supreme leader, the result of our success...! I made myself clear?

- Yes, sir...! You're right...! I had not thought of it this way...!

- So you think, before you suggest anything...! Its function is to you help me... and you do not disturb me!

The gate crossing the River Taedong has just been closed, while the warship unseen North Korean turns around! Now both boats are trapped inside North Korea. In our own transport invisible, Chin-Mae enters the control room. I walk right behind me, Fernando, also in the same room.

- Ambassador! As you had access to so much secret information and not passed on to us? (Commander Severus asks the ambassador and she had just entered the control room).

- Until a few minutes ago I did not know this craft was invisible! (The ambassador states). Everything became clear to me when we passed through the port of access to the Taedong River and no one shot at us! And just now I realized that the North Koreans also have a vessel similar to this, because it became clear that we hit on something that did not seem to be physically there! I asked that they don't shot to prevent us to stay exposed to the enemy army, denouncing so our presence. We did not come here to fight a war! Our mission is to destroy the transmission tower of Kim Jong-un. I just want to keep all of our work is lost, Commander.

- Ambassador! I do not believe you're telling us the truth! (Commander declares). I got the distinct impression that the lady knew all this and did not tell us!

- In a way you are right! My government has suggested in the past the possibility that North Korea was developing a warship invisible. We lost some spies so that we could get this information and it was never really confirmed... until now! There are whispers that this Brazilian boat also disappears from view enemy. When I joined what I'm seeing... and what you are not showing me... My final deduction was obvious...! The Brazilian attempt to hide this innovation is not working, Commander! The Americans sent agents here because they already know the existence of invisibility Brazilian naval! The secret military base of you was recently invaded by two North Korean spies! My government, like other developed countries, distrust the actual existence of this innovation in Brazil.

The commander Severus remained silent for a few seconds and then he says:

- What are all only have suspicions. Nobody really knows anything! But now we've hit almost head-on into our reflection invisible enemy! We never imagined that such a thing could happen! Especially in a country that does not invest in research and technology, as North Korea!

- Information is the best way to survive these days, Commander! (The ambassador states). For more invisible you can get... will never be enough for you to completely hide! Mankind has many eyes and ears on the ground, the sky and the water! Spies are infiltrated for years in certain social groups and from there they extract much of what governments know each other.
Some professionals are not as reliable and they tell their secrets just for a little bit of money! There's no chance of someone completely hide! Traces, evidence and some evidence will always betray a crime or a technological advantage that another country has!

- Okay, ambassador! For better or for worse... we still need the lady in this mission as an interlocutor in this Asian peninsula! But you have no doubts... I will not allow such information to be distributed out of this vessel to other countries...! No matter how many eyes and ears of the world has. They never find us easily! And if this eventually happens... we can attack and destroy the source of the information!

- Are you threatening to kill me if I tell such a thing to someone else, Commander? (The ambassador asks).

- No, ma'am! We are not murderers here! We fight on behalf of the less fortunate! We attack only those who spoil the peace and harmony of the world! We would never do that against an ally of war, like you! But I want you to understand that I will charge your silence and the silence of your country on our secret! We did not come here with the intention of winning medals or merit for future achievement that we can get together again Koreas or simply that we can prevent a nuclear war! We can not appear to the world! We need to continue maintaining our current technological advantage. Besides... nobody will believe in you if you tell the truth!

- Commander! I and my country will not talk to anyone about these vessels invisible to just meet here by coincidence. After eliminating the nuclear threat of North Korea, we have to focus on reunification economic, social, financial, geographical and historical Koreas! We will be eternally grateful to the Brazilian people and their allies from the end of this mission.

- Ambassador! We can not allow a North Korean vessel invisible becomes available from the spoils of war. The fewer countries have access to such a thing, the world will have less problems in the future.

- I fully agree, Commander! (Chin-Mae responds). The Korean people will not need a ship invisible. After today we hope that never in our history we are involved in internal conflicts or against other countries.

- When we create this equipment was only our intention to fight the guerrillas and drug trafficking in our South American continent!

- But I still have a question! As an invisible boat will achieve the other without seeing each other? And how can you be sure that this will be the vehicle to win such a strange naval battle?
- We are experts in stealth, madam! We know each other very well and we know how to fight against another similar! (Commander sovereign states).

- I then hope that your enemy is not a specialist better than you because we have a mission to accomplish before we run exposed within North Korean territory! (the ambassador states). Now I return to my room collective, if I still have a right to it!

- Make yourself at home, ambassador! (the leader Severo states). The lady is not bound, but our artificial intelligence will be keeping an eye on their activities inside until the end of the mission.

The ambassador thanked her head, agreeing with the decision of the commander. Soon after she returns toward the dormitory. At this moment the soldier Ricardo, responsible for radar signals, informs something urgent, and this makes Chin-Mae give up going to the back of the boat:

- Commander! Our radar just detect the position of the enemy (the soldier tells Ricardo). He is getting ready to shoot at us with heavy weapons!

- Lieutenant Julius! Firing as the gun is made! For though we are not located by North Korean military, who are armed on the banks of this river, throw projectiles at low speed!* (The commander shouting orders Severus).

Lieutenant Julius shoots quickly, hitting the pipe, the enemy cannon, and that the damaged, preventing it from firing. As a result, and as scheduled earlier, the computer fires just three other shots in enemy vessel, hitting the hull along the water surface! But these projectiles could not pierce the robust structure naval Asian! A little fire burst pipe, our weapon during the shooting, but she quickly faded. The sound was muffled, which was shot from inside of our boat, preventing North Korean soldiers, stationed on the riverbank enemy could locate us. Now the two commanders take new decisions. Severus ordered the team:

- Major Margaret! (pilot boat invisible Brazilian). Crank the engine core so we can move on so we lateral. When we move in this new direction, you stop immediately and all other propulsion systems that can make some kind of noise! We'll dodge the shots of the enemy. Soldier Carlos! (responsible for the images projected on the outer hull of our boat, and he is also nicknamed the filmmaker). Preparing to release the image of the whale swimming on the surface of the water! Major! So we move fifty yards or more laterally, engage the outboard at high speed so that we can get out of here. I want to sync between the release of the image and the motor drive! We'll fool the Korean military and we'll sail upriver to us complete our mission. Soldier John! Once the four artificial insect meet our invisible enemy you order they land on it and they spread symmetrically over the entire surface. So we will have a visible target when we meet again in the return of our mission.

- Sir! We already have the images of the structure of our vessel sent by the artificial insect that flies out there around us! (Soldier John comments). There was no external damage relevant, only a few scratches! We can go on and on this way until we return to Brazil. The irrelevance of the damage we do not denounce the enemy.

The North Korean enemy ship is with bigger problems at the moment:

- Sir! We can not shoot again (the shooter eastern states, and the cannon he retreated to the interior of the vessel). They damaged the pipe, our cannon! The other shots did not affect our boat.

- Run at full speed astern! (eastern commander orders). I want the cannon bow repaired immediately! (bow is the front part of the ship). We We will reposition so ago and we followed them slowly, trapping them before they complete the mission!
The commander of the North Korean vessel, now thoughtful, asks himself questions about what happened:

- Why does he not destroy us? Maybe they do not have another chance like this in the future! Did we overestimate the Brazilian boat? Or perhaps he thinks he can complete the mission before our final battle! Anyway I have to destroy it!

- Sir! Our troops on the river banks are reporting the presence of a whale fast sailing upriver!! (one North Korean soldier says to his superior).

- Whale?! That's impossible...! There is a whale! It is our enemy! We need to follow it! Mend soon our cannon! Let's follow him slowly!
