Cheng Xin opened his eyes, and he was in a dark and damp cave. There is a fire next to it, and the body is warm and comfortable.

Who am I? Where am I? What am I doing? He frowned, feeling like his brain was being churned into a mess, unable to think or recall.

"Young Master, are you awake?!" A surprised voice sounded at the entrance of the cave, it was Uncle Fu who had returned, and he was still carrying a dying rabbit in his hand.

It is said to be a rabbit, but it is actually half a man tall, with a strong body like a hyena, and two large teeth that are even sharper and frightening.

"Hmm......" Cheng Xin can't remember anything now, of course he doesn't know who the middle-aged man in front of him is, so he can only hum twice to deal with the past.

Uncle Fu shook his head and smiled bitterly indifferently, as if he had already gotten used to it.

He skillfully cut open the rabbit with the saber in his hand, and picked out a few pieces of lean meat and roasted them over the fire.

While drumming the meat, he talked to Cheng Xin, even if the other party never replied, he enjoyed it.

"Xiao Ning, it's time to cheer up, people can't be resurrected after death...... In fact, there is nothing bad about being a wanderer......"

"When I went hunting today, I encountered a three-meter-tall steel-maned grizzly bear, I'm afraid only a B-level ability can handle it, but fortunately it didn't notice my ......"

After a while, the cave was filled with the smell of meat.

Estimating that the heat was about the same, Uncle Fu cut the roasted meat into two parts, and sent one to Cheng Xin.

The barbecue was delicious and strong, but when he chewed, Cheng Xin felt a hot pain coming from the back of his head.

He was a little strange, but still able to endure and enjoy the food.

After the meal, Uncle Fu suddenly took out a pot of wine, and took out a small jar of drug powder with unknown effect and approached Chengxin.

Cheng Xin took a few steps back vigilantly, and Uncle Fu was both heartbroken and unbearable: "Xiao Ning, if you don't change the dressing, your injury will never get better, and you have to endure the pain." ”

Although Cheng Xin still didn't understand what the other party meant, there was an inexplicable sense of trust in his heart, and the ghost made God nod his head.

Uncle Fu walked around behind Cheng Xin, pressed his shoulder, carefully soaked a piece of cloth with wine, and wiped the wound on the back of Cheng Xin's head.

The wound was very large, the flesh was blurred, unusually hideous, and even faintly exposed small white bones, it was hard to imagine that anyone could survive such an injury.

Cheng Xin's eyes suddenly widened, his teeth clenched, and his whole body trembled—the pain of the wound under the stimulation of alcohol was still intense.

Uncle Fu forcibly endured the shaking of his hands and barely wiped the back of Chengxin's head, earlier in order to prevent the wound from being infected and to facilitate the application of medicine, all of Chengxin's hair had been treated clean.

After the disinfection was completed, it was time to apply the medicine, and under the control of Uncle Fu, the drug powder was evenly sprinkled on Chengxin's wound.

"Ahh Cheng Xin finally couldn't bear it anymore and exhaled in pain, the severe pain of this attack was ten times stronger than the previous one!

Suddenly, a flash of lightning struck his head, and he seemed to remember something......

It was late at night, the bonfire was still burning, Uncle Fu was sleeping with his head up, the snoring was shocking, and the saber was still in his hand, not daring to leave.

Cheng Xin didn't feel sleepy, got up and came to the entrance of the cave.

Silver moonlight poured down and spilled onto his face.

He suddenly laughed silently, so weirdly that the corners of his mouth were almost up to the base of his ears.

............

In 2040 A.D., an asteroid from outside the sky smashed its head into the earth, and although it was intercepted and shattered by a nuclear bomb in space, there were still a few fragments of meteorites that slipped through the net and smashed into the earth without pain.

At first, no one cared about their effects, but soon things changed.

Asteroid debris brings with it an element that Earth does not have, and its elemental gases react in incredible ways once they are absorbed into living organisms.

Those with suitable physique can use this to complete their evolution, generate α particles in their bodies, and obtain unique superpowers, which can be improved after long-term absorption; Those who are not physically fit will not have any noticeable effect if they touch it.

So the end times for humanity have begun, a large number of weak ordinary people have been slaughtered by other species that have absorbed new gases to gain abilities, and no matter how cute the little animals in the past may now suddenly become fierce and unfounded.

In just a few months, the overall human population has declined dramatically.

In the chaotic apocalypse, some human beings have evolved and mastered superpowers, and in order to protect other compatriots, they have established large and small gathering places to resist the invasion of evolved creatures.

Finally, after 90 years of the end of the world, human beings were once again stronger than other species and became the top of the food chain, and humans at that time began to call their era ...... The new world!

Cheng Xin was born in the 20th year of the new century, he is known as one of the few geniuses in the world, before the age of 30, he won the Nobel Prize, which represents the highest honor in the scientific community, five times, and is also the top expert in the field of archaeology.

When he was 33 years old, he calculated that another planet in space would have a trajectory that coincided with Earth's trajectory in a decade later.

It's hard to believe that humanity's home planet has such a bad fate, having suffered two crashes in just one hundred and sixty years.

It's just that this time humanity's luck is not as good as last time, and this new visitor is half the size of the moon, and even if they try their best, it won't help.

At the moment before the destruction of the earth and the extinction of mankind, Cheng Xin got into the quantum machine that he had painstakingly developed for ten years.

He didn't want to steal his life, and the machine was not his escape device, but the only hope for humanity in his imagination - Cheng Xin wanted to send himself back to the past and save the world!

The quantum machine first injects a certain agent into the user's brain, so that it can maintain a certain degree of aggregation in the microscopic state, and can be revived after encountering a suitable living environment; It then instantly breaks down the user's brain memory area into quantum units, which are then emitted simultaneously at speeds faster than the speed of light.

In other words, the machine can break up the memory area of the user's brain and send it back to the past, which is absorbed by the human brain at the time and then reassembled to cover the memory area of the absorber's brain...... In Xianxia, this is called snatching away.

............

Absorbed into new memories, this person is called Chen Ning, and his identity is the son of the original high-ranking son of a small human gathering place in the last days.

His father was exiled due to his defeat in the political struggle, and the family unfortunately encountered a B+-class creature winged tiger during their migration to the wild, and was killed and injured, only Chen Ning and the old maid Uncle Fu escaped.

In that battle, Chen Ning was injured in the back of the head, and his brain was injured and he happened to absorb new memories under his confusion, which was covered by his memory, resulting in confusion in his memory, which led to today's incident.

Now that Cheng Xin's memory has completely occupied Chen Ning's brain, in a sense, he has been reborn.

This is Cheng Xin's second life, and he should have been buried with his compatriots for this planet in that disaster.

In this life, he will no longer live for himself, he will carry the hope of the salvation of all mankind on his shoulders!

Sorting out the memories of the original master in his mind, he knew that the end of the world had begun thirty years.

This is the time when the social order of human beings is most seriously damaged, and people are in an unsafe and stable environment, accustomed to the law of the jungle, and only the strong are respected.

Cheng Xin, no, it's Chen Ning now, he stopped smiling, and there was a resolute look in his eyes.

With all the mature science and technology he has mastered, as well as advanced information resources, he is destined to become the real king of the world, no matter what stands in front of him, he must be crushed!
