It's been three days since I came into this world.

In the sky, the layers of air flow of cyan, red, and black are intertwined like a huge canopy, blocking out the sunlight.

The effects of the nuclear explosion 200 years ago are still being eliminated today.

The hole in the ozone layer, the massive scale of nuclear radiation, the toxic sewage drains, and the unknown and dangerous species caused by mutations all make this land dangerous.

Yu Qing sat on the steps in front of a row of stone houses, surrounded by a group of teenagers about his age, all looking ahead with serious expressions.

This is the J12 base, a gathering place where humans extend into the wasteland for the purpose of gathering mines not far away.

A day earlier, a tide of beasts had appeared in the wasteland, and was sweeping towards this isolated base.

......

Yu Qing crossed.

He was sure of that.

Because no one can lie on the bed with their front feet still on their back feet, the back feet come to this place where birds don't.

It's been three days since he came to this world, and Yu Qing has already figured out where he has come.

He traveled to Earth.

This statement is a bit incredible, to be precise, Yu Qing traveled to a parallel plane of earth.

This world is similar to the world he used to live in, it is a planet in the solar system, there is a moon outside, and there is no such thing as a double moon hanging in the sky.

Even the history is similar, the unification of the Great Qin and the establishment of the Han Dynasty, and this similarity has continued until the early part of the 21st century.

Around the year 218 of the Gregorian calendar, a massive starship floated from space, and from that time on, history began to change.

With the arrival of the starship, many strange things happened on Earth.

In the beginning, the growth rate of plants accelerated rapidly, and crops that could only mature in the previous six months experienced the process from birth to senescence in just ten days.

And over time, this change has not only appeared in plants, but also in humans and animals, and some strange changes have begun to appear.

In the most popular way, the era of Reiki revival has arrived.

Under the nourishment of the aura, the lifespan of human beings has increased, the body has become stronger, and the limits of the human body have been broken through without limits, which seems to be developing for the better.

But something even more dangerous has happened, because it is not only humans who have mutated, but also animals.

Just like those pigs that were originally raised for food, scales have grown on their bodies, and some of their bodies are covered with sharp armor, and their teeth have turned into fangs, and they can even easily bite through the fence that traps them.

The piglets finally turned over and became slaves, from humans eating pigs to pigs eating people.

Animals far outnumber humans, and the mutated animals become brutal and bloodthirsty, and battles occur everywhere.

In the beginning, it was just animal populations in the wild fighting each other. But with the birth of the monster king in the beast herd, these monsters gathered into a beast tide and attacked human cities on a large scale.

In the first few years of mutation, humans were able to defeat monsters with thermal weapons, but as monsters mutated more and more powerfully, thermal weapons no longer worked against them, and when the fate of the human race was at stake, countries around the world started a plan called 'nuclear war'.

The application of nuclear weapons has indeed reduced a large number of monsters, but there are too many monsters in the world, and this is only a temporary relief from the pressure on human beings, who have survived for a few more years.

Fortunately, with the blank period of the past few years, human beings have cracked the information on the spaceship through wisdom, mastered a cultivation method called 'Reiki Introduction', and officially embarked on cultivation, which gave human beings the ability to fight back when facing monsters.

Now.

Two hundred years have passed since the revival of Reiki.

The original state system of the world no longer exists, and all parts of the human race, all nations and races, have formed a new federation.

The Federation has formed a survival alliance for humanity around the world.

The Federation has a total of thirteen holy cities on the earth, and in the original land of China, there were as many as five holy cities.

Because the Federation has the largest number of Chinese people, Chinese has become the lingua franca of the Federation.

......

Yu Qing crossed over, although he didn't get the memory of his original body, but he also learned some facts through side knocks.

The name of this body is also Yu Qing, who is seventeen years old this year and is from Jiangnan City, a second-tier city.

Yu Qing originally lived in a wealthy family, the family did small business, and the original life was harmonious and beautiful.

But when he was twelve, his father took over a big business, went to the wasteland with his mother, and never came back.

Then soon after, the family went bankrupt.

Debt collectors came to the door one after another, and the family's house and savings were all used to repay the money.

As a result, Yu Qing and his ten-year-old sister became orphans and wandered.

Fortunately, the federal system is not bad, and there is a wealthy family with no children, and through the federation, they want to adopt the Yu Qing brothers and sisters.

It's just that Yu Qing was competitive at that time, and he didn't believe that his parents were dead, so he refused the couple's request for support.

So.

At last.

The family only adopted their sister, and twelve-year-old Yu Qing signed up for the base development work.

In the original land of Huaxia, there were five large holy cities, seven first-class cities, and more than thirty second-level cities, and there were countless bases that went deep into the wasteland.

After the revival of the aura, there are too many resources in the wasteland where the monsters are entrenched, such as spirit ores that can make weapons, and like all kinds of rare medicinal materials, which can only be found in the wasteland.

In order for humans to develop, they must ask for resources from the wasteland, so the existence of the base is particularly important.

Yu Qing signed an eight-year contract with the J12 base, as long as he worked in the base for eight years, after the work was over, he would get military status, and when he returned to the city, the Federation would give him honor and assign him a good job.

From the age of twelve to seventeen, Yu Qing has been working in the J12 base for five years, as long as he works for another three years, he no longer has to worry about his future life, and the Federation will give him protection.

Yu Qing's work in the base is easy and not dangerous, his job is to control the mecha to dig up ore.

In the past two hundred years, humanity has cracked many of the technologies of that spaceship, such as high-attack energy weapons, which have become the standing weapons of the military at this time.

And the weapon of war, the 'mecha', has also been developed.

This is a bit like an anime Yu Qing watched in his previous life, the kind of battle mech in "Rebellious Lelouch", which can fly, has an energy shield, and has high-energy weapons.

Of course, with Yu Qing's current control technology, he couldn't control this kind of complicated battle mecha at all, his job was just to control those bulky industrial mechas.

Because the base is deep in the wasteland, it is built in the wasteland, and it is too far away from the human city, so even if there are troops stationed, there is no guarantee of safety.

After all, outside the base, there are a large number of monster races.

Therefore, the mortality rate of base workers has always been the highest among all industries in the federation.

A bite from a tiny mutant mosquito can kill you.

And what no one could have imagined was that just yesterday at noon, a beast tide attacked the J12 base.

"Big fish, do you think we can survive?" asked a chubby teenager next to Yu Qing.

"Li Wei, we have to believe in the army. Yu Qing looked at the constant roar in the distance and said to Li Wei.

The battle on the front line was fierce, and in fact, Yu Qing was a little worried in his heart.

Although the base is a resource point of the Federation, it is impossible to have too much standing military strength, and once the beast tide is formed, it will be too terrifying.

Moreover, even if the Federation had sent a rescue force to the J12 base, it would take at least three days to arrive.

Can the J12 base last three days?

"If the monster really attacks the base, what should we do?" Li Wei's little face trembled.

"Either you kill it, or it eats you, what else can you do?" Yu Qing shook his head, what is it, people have crossed the capital with a group of wives and concubines, why do I have to become a monster ration when it is my turn?

It's so dangerous, I don't cross it, okay?

I regret that I shouldn't have written a novel.

"But I can't do anything but control the mech. Li Wei sighed.

Yu Qing comforted him: "Don't worry, you will definitely live longer than us." ”

"Really?" Li Wei seemed to grasp a life-saving straw.

Yu Qing nodded very seriously: "If you grow fat, they will eat for a longer time, so you live a long time." ”

Li Wei: "...... don't scare me, okay?"

Yu Qing glanced at the fat man and decided, if the base really can't be saved, when it's time to escape, he must take this fat man with him.

Because.

This is my friend!

More because.

This fat man can't outrun himself!
