The manufacturing technology of the super giant war armor is extremely complex, and due to the huge size of the body, the forging and energy transmission of special metals alone are huge problems.

If the original space shuttles, aircraft carriers, intercontinental missiles and other cutting-edge weapons show the strength of a country, then the super giant war armor shows the strength of the entire human civilization.

With the power of humanity all over the world, and even the tremendous support provided by the Salvation Army, only thirty-three super-giant war armors have been manufactured in the world.

It can be said that each super-giant war armor is the brainchild of human civilization, and it is the pinnacle of the survival and reproduction of this human species on the earth.

It is precisely for this reason that these weapons of war can be said to be baby bumps, each of which has a unique signal frequency band, and is equipped with a signal transmitter that is tens of thousands of times more reliable than the black box of an aircraft, so that it can get the fastest support in distress or even missing.

What Shen Feng was holding in his hand were these few signal trackers.

At this time, he couldn't help but feel a little excited, took a deep breath, pressed the button on it, and turned on the screen of the signal tracker.

The light flickered, and a world map appeared directly on the screen, followed by dozens of flashing points of light.

This world map is still the map of the world before it was completely submerged by the sea, which can't help but make Shen Feng feel more cordial.

Thirty-three flashing points of light were all over the world, and Shen Feng could see that there was a point of light near San Francisco, which was obviously the wreckage of the Oglala Crazy Horse he had encountered earlier.

And in an area of the ocean a little far from San Francisco, there is also a faint point of light flickering.

If the prediction is correct, this sea area is the sea of fog he has been to before, and that flickering point of light is probably the super giant war armor bloody Kraken destroyed there.

At that time, he only saw the quantum state phantom left by the bloody Kraken, and now he thought that part of the wreckage should be buried at the bottom of the sea......

Originally, after Shen Feng came to the end of the water world, although he brought a sail battleship and obtained the core of the quantum force field by chance, he still had a sense of powerlessness in his subconscious when he thought of the endless world beasts.

Now that I have this signal tracker, I can't help but feel my blood boiling, and finally I have the feeling of seeing the sun.

A thought flashed through his mind.

"Jingwei, check the data you just got, has there ever been a nanomachinery cluster in this world? In this world, have I ever manipulated the gray tide?" Shen Feng quickly asked.

Jingwei immediately replied: "No, there doesn't seem to be nanomechanical swarm technology in this world, if you in this world also have the 'real doomsday game' system, the doomsday world he entered should be different from you."

Shen Feng nodded slightly.

He'd thought of that before.

Assuming that there are countless parallel universes and parallel worlds, then many of these worlds should have fallen to the end of the world, and only the "he" of the peaceful universe can be selected to enter a specific apocalyptic world to carry out tasks. Each "he" is different, and the mission he performs in the apocalyptic world should also be unique.

In this case, it will make sense.

Shen Feng nodded slightly, his eyes flashed with essence, and he said with a little excitement:

"I remember...... Arthur Shelton originally seemed to have created a prototype of a nanobot from a broken garage in San Francisco......"

Jingwei's voice immediately sounded, also with excitement:

"Yes, I still remember the specific location of his house, tsk, yes, Xiaofeng, it's worthy of you, or such a chicken thief, I hope there is also an Arthur Shelton in this world who happened to make a nanorobotic bug."

The Super Giant War Armor itself has a restraining effect on the World Beast, and if it can be used in conjunction with the nanomechanical cluster, it is definitely a great killer weapon to hunt the World Beast!

A lot of things will be much easier!

Thinking of this, Shen Feng couldn't help but be even more excited.

After taking a few turns around the Fortress-3 laboratory and inspecting it inside and out, Shen Feng made an unexpected discovery this time.

A small submersible with a capacity of only three people.

From the perspective of form, it should have evolved from the "Qianlong" series of deep-sea submersibles in China.

The submersible was supposed to have been in the laboratory before the Battle of San Francisco, but it was not large enough to survive a tsunami.

And none of the more than 2,000 Salvation Army soldiers chose to leave their companions behind, so the only submersible remained.

Shen Feng carefully inspected it and found that there was nothing wrong with the submarine except for some parts that were somewhat aged.

After all, more than 200 years have passed, and no one has come to disturb them, and the circulating system of the submarine base has always maintained a constant temperature and humidity state, which will not cause any damage to the submarine.

Under the guidance of Jingwei, a few parts were replaced, and the situation of the submarine itself was tested, and Shen Feng got in.

After making sure that there were no valuable items other than those scientific research data, Shen Feng pressed the laboratory's submarine ejection device, ejected the submarine from the ejection channel in the submersible, and left the undersea laboratory building that carried a period of human civilization.

Turning his head to look at the window behind him that shone with a little light, Shen Feng couldn't help but sigh a little.

Although the control system and circulation device in the laboratory are powerful, it is already the limit that it can last so long, and even if the energy of the nuclear fusion reactor is sufficient, it is difficult to sustain it forever.

When the sealing device in the laboratory fails and the control system completely fails, the sea water with extreme pressure will rush in, completely burying this history.

This small submarine did not disappoint Shen Feng, sailing extremely fast, and the two lights were like two sharp swords, splitting the endless darkness at the bottom of the sea and illuminating the ruins of San Francisco under the sea.

From the point of view of the energy system, the energy inside should be enough to support several days of sailing.

Jingwei unfolded the map of San Francisco in his database on the screen of the submersible, and compared the data of some streets that the submersible had walked, and quickly simulated a map of the ruins of San Francisco under the sea.

Judging from some of the areas they have just walked, the San Francisco of the apocalyptic world of the water world is roughly similar to the original San Francisco they are familiar with, and if Arthur Shelton of this world really exists, then the location of his home should be very similar.

The engine of the submersible drove the propeller to stir the seawater, moving forward in the high-pressure and low-temperature submarine salt current, Shen Feng couldn't help but be a little glad that he had found this small submersible, otherwise San Francisco was so big, he didn't know how long he would swim by himself.

Sneaking through the once-bustling streets, through the whole of San Francisco to the suburbs, finally appearing in front of the ruins.

According to the memories in the Jingwei database, this is the home of Arthur Shelton in the original world, where the nanobot was created.

To be exact, it should be the warehouse of Arthur Shetton's house. As the villain boss in the apocalyptic world of Gray Tide, Arthur Shelton can be said to be an out-and-out genius.

And in this world, judging from the layout of the building, he should also exist.

But there is only rubble here.
