Crossing this kind of thing is already very familiar to Wang Bo.

As soon as his eyes are opened and closed, it is a new world, and this time is naturally no exception, when Wang Bo opened his eyes, he entered a new world.

This time, the world is still the earth, and it is still a modern society, and time has entered the 21st century.

And this time, the person Wang Bo replaced was a mecha maintenance engineer.

Interestingly, the mecha repairman replaced by Wang Bo was also called Wang Bo.

For a moment, Wang Bo almost thought that this Wang Bo was actually himself in a parallel world, but he quickly reacted that although this world was also the earth, it was not a parallel world of the earth.

And this Wang Bo is not a parallel world itself.

It's just the same name.

To be honest, when he first saw that his identity turned out to be a mecha repairman, Wang Bo almost thought that he had come to the cosmic era.

However, he quickly realized that this was not the cosmic era, but the twenty-first century.

But this is not a peaceful twenty-first century.

On the contrary, it is a turbulent twenty-first century in which humanity is already on the brink of life and death.

And the reason why human beings are on the brink of life and death in the 21st century is not because the earth is going to be destroyed, nor because the sun is going to explode, but because human beings have encountered monsters.

And this matter has to start from 2013.

In 2013, a parallel cosmic breakthrough appeared in the depths of the Pacific Rim.

Then, a gigantic beast rises from the ocean and lands in San Francisco and the surrounding coastal cities.

San Francisco is devastated by behemoths.

Humans have taken a series of measures and used a variety of weapons, including tanks, planes, rocket artillery, missiles, and more, but for the behemoths, it is of little use.

Eventually, three cities were destroyed by the Behemoth, and tens of millions of humans were injured or killed.

Humanity eventually couldn't take it anymore and used the ultimate weapon...... Nuclear weapon!

And the nuclear weapons also lived up to expectations and killed the behemoth.

But what humans on Earth never expected was that the blood in the body of the giant beast was highly poisonous, evaporating in the air, and the sixth-largest metropolitan area in the United States: San Francisco-Oakland Bay turned into a barren land.

This disaster is known in history as the "San Francisco Incident".

The day the monster landed is called "K-DAY", which translates to K-Day.

When the incident was over, the humans named the monster and gave it a code name...... Intruders.

Just when humanity thought it was going to be over again, six months later, a second monster swept in and destroyed the second coastal city, Manila!

Manila is the capital and largest city of the Philippines, one of the most cosmopolitan cities in the world, and one of the most diverse cities in the world. ”

The destruction of this city has undoubtedly brought great harm to mankind.

Then, as time passed, Tokyo, Sydney, Hong Kong and other places appeared one after another. At this time, people knew that the monster attack on humans was not an end, but just a beginning.

What's worse is that according to scientists' analysis, if you want to fight monsters, you can't blindly use nuclear bombs, because although nuclear bombs can destroy them, they will trigger a large release of toxins in their bodies.

This is an act of "natural selection" that changes the earth's atmosphere, soil, and water environment by committing suicide to exterminate life on earth. In other words, although a nuclear bomb can kill a certain number of giant beasts, before the giant beasts die, humans will finish the game first.

But what is even more cruel is that without the use of nuclear bombs, human conventional weapons will not be able to defeat monsters at all.

This will make the monsters even more rampant.

To be honest, when Wang Bo saw these contents from the information left by the mecha repairman, it was enough for Wang Bo to judge what kind of world he had come to.

There is no doubt that I came to the world of the Pacific Rim.

The current humans don't know that the monster in their mouth invaded Earth because of the orders of the alien pioneers.

As early as the Triassic period, the pioneers had set their sights on the earth, but at that time, the earth's atmosphere was extremely high in oxygen, and the monster troops could not adapt to the environment, and finally the colonization mission ended in failure.

However, with the advent of the era of civilization, the pollution of the earth has increased, and the carbon dioxide content in the atmosphere has increased, reaching an environment that can support the survival of monsters, and the second colonization mission has begun.

That's why there was the invasion in 2013, and that's why there were monster invasions again and again.

For humans, it's not monsters that are truly scary.

Rather, pioneers.

Monsters are nothing more than weapons created by pioneers, specifically for the purpose of exterminating humanity.

So there is never peace between humans and monsters.

This is a war to the death.

Once the human race fails, it will be wiped out and completely disappeared from the earth, and will never exist again.

The pioneers, on the other hand, will become the new masters of the earth, stepping on the corpses of human beings to build a more prosperous civilization.

On the other hand, although the pioneers have great intelligence and civilization, they will not easily fight each other with humans, after all, wisdom and combat effectiveness are two different things.

In terms of fighting, they are actually also at the level of weak chickens.

But they can create monsters and send monsters into the earth through wormholes, so as to completely wipe out human beings.

But human ingenuity is infinite, and after several invasions, a scientist from Gaspar Sheffield had an inspiration, and this inspiration came from his son.

Once, when Gaspar saw his son playing Godzilla with a toy robot in the house, he was inspired to build a monster that belonged to humans, a giant mecha that could be compared to monsters.

To this end, Gaspar found Kathleen Lightkapp, a neuroscientist at the US Defense Advanced Research Projects Agency and his old friend.

By the way, the relationship between the two men is not simple, Catherine is a student of Gaspar, and the two have been eye-to-head since college.

However, at that time, Gaspar had already made a lifelong agreement with his wife Nancy, so Catherine's identity at that time was actually what ordinary people call a third party.

After Gaspar got married, the family was harmonious, and his son was well-behaved, but he was still disconnected from Catherine.

After all, for Catherine, Gaspar is also a very attractive man.

Even if the other party already has a wife and children, she still misses this man, and whenever Gaspar is in need, she will be obligated.
