——

A.D. 2537.

It is also the year 496, the years after the New Yuan era, which anthropologists call the post-human civilization era

Building K, Bixia District, Nanzhou City.

"Today is the 17th, and it's been a week since the last time...... Not...... The injection of high-purity energy for Xiao Feng. Mu Hua smiled and walked to the bedroom upstairs.

The family of three had just finished lunch, and her mother Liu Lan was cleaning up the dining table, 17-year-old Mu Feng came to the sofa in the living room alone and sat down, clicked on the glass table in front of him, and a spotlight display was projected on the empty wall in front of him and began to show the show.

Mu Feng looked upstairs, couldn't help but sigh with a wry smile, and after a while, he heard the footsteps of the stairs, he immediately restrained his heavy and bitter emotions, and once again showed a cheerful and quite ignorant teenager mentality.

Brother Muhua came to the living room with a box and sat beside him, opened the box and took out a blue crystal the size of half a small finger and shaped like a rectangular block.

This is the crystallization of high-purity energy, and it is also the crystallization of human science and technology at present, such a small piece of energy crystal can supply the electricity of the entire Bixia community for nearly three months, and it is outrageously expensive, such a small piece is worth 20 million Singapore dollars.

At this time, Mu Hua concentrated on concentrating, took out a bottle of 460 ml of specially configured drops from the box, and then integrated several bottles of small reagents into it, and finally put a small high-purity energy crystal into it.

The energy crystal was quickly dissolved when placed in the potion liquid, and the colorless solution turned into a bright blue liquid, and after two seconds, the blue liquid turned into a colorless liquid again.

Mu Hua hung up the medicine bottle high, connected the infusion tube, and said with a smile: "Xiao Feng, stretch out your hand." ”

"Hmm......" Mu Feng nodded and stretched out his left hand.

Mu Hua put a bandage on his arm, and the blood vessels on his arm were obviously raised, the tip of the needle of the infusion tube pierced the blood vessels, and the liquid full of pure energy began to gradually inject into the body.

Mu Feng silently watched his brother pack up his things and put them back in the bedroom, and came to the living room again and said loudly to the kitchen: "Mom, I'm going to the academy!" ”

The usual words came from the kitchen: "Be careful on the road!" ”

"Brother......

Mu Hua had just walked to the door when Mu Feng suddenly spoke.

"Thank you, brother. If it weren't for you to give me life, I would have died a long time ago. But I'm living and you're a drag...... I'm ......," Mu Feng said softly.

Mu Hua was stunned, and then said with a smile: "What are you talking about?" We are brothers, brothers! If Brother sat there and knocked out the water, Brother believes you would do the same, right? Well? ”

Mu Feng's nose couldn't help but be slightly sour, and he nodded heavily.

Seeing this, Mu Hua couldn't help but smile, and said softly: "Don't think nonsense, your brother and I are geniuses, destined to become real powerhouses, aren't they just a few energy stones." Remember, we are brothers, and this is more important than anything else. ”

Mu Feng looked at his brother with a cheerful smile, and there was an encouraging gaze, and he nodded heavily.

That's right, we are brothers, and this is more important than anything else.

Mu Hua went out, Mu Feng looked at the door where he disappeared for a long time, and then looked up at the ceiling. He and his brother were both born in the era of post-human civilization, and he had a strange disease since he was a child, he needed to regularly ingest a high amount of pure energy to continue his life, and the energy contained in his body was simply not enough to supply, once there was no energy intake from the outside world, this strange disease would suck up the energy of his body and kill him.

This is an incurable disease, and even with the current super-high medical means, it is helpless, like a bottomless pit, and the demand for energy can never be satisfied.

Time passed, Mu Feng clicked on the glass table to change the channel, and when he switched to the documentary channel, a historical documentary called "Catastrophe" was playing, and the voice of the narrator came into his ears-

"In the middle of the twenty-first century, a supernova located in the constellation of the North Sky exploded, in the long years, this huge star was obscured by dust, and the development of science and technology until 2037, the progress of human beings in deep space exploration capabilities was finally discovered, but it was too late, the existing technology of mankind could not get out of the earth, and the destructive power carried by the supernova explosion entered the solar system three years later, and the catastrophe befell ......"

"Seven light-years away is out of reach for humans, but the explosion of a supernova at such a close distance is enough to have a devastating impact on life on Earth."

"The ozone layer on Earth was destroyed first, and deadly radiation and cosmic rays carried out a wanton and murderous extermination of all living things on Earth."

"Although the nations of the world learned that the end of the world would be the end of the world in three years, our ancestors still tried to keep our civilization alive by luck with the last glimmer of hope and hope, and built a shelter in despair to resist the impact of a supernova explosion on Earth within three years."

"One data shows that in 2039, the world will have more than 9 billion people before the end of the world, after the end of the world, 90% of the world's population will die in the catastrophe, and the remaining 1 billion people will survive through the shelters that were secretly built three years ago and the shelter of the old nuclear shelters."

"The survivors are perhaps the most unfortunate, even though the Vault was built to protect against cosmic rays to the maximum extent and the limits of humanity's existing technology, but without the natural shield of the ozone layer, coupled with the powerful energy impact of the supernova, the Vault's ability to protect against radiation is so fragile."

"The deadly radiation has caused the surviving human beings to suffer from radiation sickness, and the bad news has come again, and human beings have begun to die on a large scale for the second time, and nearly 300 million people have died in just one year, and the 700 million people who survived for the second time have successfully obtained strong anti-ultraviolet physical fitness and barely survived, and it has also become the fire of our human civilization."

"The last survivors are mainly concentrated in Asia, North America, Eastern Europe, and South America."

"Although the survivors have gained strong radiation resistance, they are limited to the shelter, and they cannot survive without wearing radiation protective suits when they leave the shelter, and they can only spend the rest of their lives in the shelter, and it has become a luxury to see the real sunlight."

"After the catastrophe, offspring were finally born, and scientists were pleasantly surprised to find that the children born after these disasters were more or more vibrant, and they could easily break the world records held by mankind in various fields when they grew up."

"Eventually, scientists determined that the offspring born after the catastrophe had re-evolved, and the catastrophe gave the surviving humans an unexpected evolution."

"Just as the surviving humanity abandons its grief and decides to rebuild civilization and confidently lead it to a more glorious chapter, they discover that the true nightmare has only just begun......"

"After the supernova explosion, 7% of humanity still survived, which means that not all other species on Earth are extinct, the surviving human descendants have evolved, and the descendants of the other species that have survived have also evolved!"

"Human beings have survived thanks to the existence of shelters, the terrible thing is that other surviving species have no peripheral protection, and what is more deadly is that their descendants have not only evolved, but also the evolution of life forms is more prominent than that of humans, and some creatures have not only evolved their physical functions, but also strengthened their brains, in other words, they are more intelligent, and the rise of all things is undoubtedly a disaster for human beings......"

"The catastrophe destroyed the ecological environment of the earth's species diversity, led to the collapse of the food chain, and gradually began to form a new biological chain in the following time, and the surviving organisms were instinctively looking for their place in the biological chain, and soon some organisms were eliminated again......

"In the process, the human survivors faced a third catastrophe, this time from the attack of mutant creatures, the four major survivor concentrations in the world were attacked at almost the same time cut-off point, because there was no experience that caused multiple shelters to be destroyed by mutant attacks, and tens of millions of people died and became their food."

"However, we humans are not powerless, and the mutants caught humans by surprise, and soon our ancestors actively organized defenses and began to quickly upgrade the security of shelters that had not been attacked."

"But the plan to rebuild civilization has been dealt a heavy blow, the scope of human activities has almost been compressed in the shelter, and the outside world full of deadly radiation has become a world of mutant creatures, a forbidden area for human beings, and humans and mutant creatures have since fallen into a long war, until today, although we have gained a foothold and opened a chapter in the era of post-human civilization, we are still not completely sure that we can win this war......"

Mu Feng turned off the spotlight display, and saw that the hanging water was almost finished, he looked up at the ceiling again without saying a word, and saw a photo frame on the wall with the peripheral vision of his eyes.

It was his father, Mu Xian.

Mu Feng couldn't help but recall a major incident that happened when he was eight years old, when Nanzhou City was attacked by a terrible monster group, and the defense of Nanzhou began, and his father Mu Xian died in the defense.

The pension money issued by the government was also used for his own strange illness.

"My brother is a talented martial artist, in order to continue my life, he not only took out the precious resources he needed, but also risked his life to hunt mutant creatures in the ruins of the forbidden area to make money......"

"I'm just a piece of waste, and I'm dragging down my brother and this family!" Mu Feng gritted his teeth, his fists clenched, and his nails were already deeply sunken in his palms.

After the hanging water was finished, Mu Feng could clearly feel that his body was not so weak, and the strange illness was obviously fed, and he was not thinking about his physical functions.

Empty bottles and tubes are packed away and disposed of in separate bins.

"Mom, I'll go out for a while."

"Stay safe, don't go crazy!"

Mu Feng retracted his gaze and said no more, silently opened the door and walked out of the Bixia community.

Nanshu is a very large city, according to the latest statistics, this megacity lives in more than 210 million people, the size of Kyoto, in the Asian region, a total of 9 cities, concentrated 800 million people, and Nanshu and Kyoto alone accounted for more than half of the total population.

These 9 megacities have all developed on the basis of the original Vault, and the vast expanse beyond the city is the ruined land that people have heard of, where only powerful warriors and armies armed to the teeth can set foot on it, and ordinary people entering the ruins even if they don't encounter mutants, the lethal radiation is enough to kill them in ten minutes.

At this time, Mu Feng was walking on No. 13 Street, and the pedestrians on the road were busy.

Forty-six kilometers away in front of him was the center of Nanzhou City, the center of which was no man's land, and where the core of the whole city was. A giant pillar of light visible to the naked eye soared into the sky, spreading out to all directions at a height of fifty kilometers at its apex, thus forming a curved energy shield, which not only blocked the radiation that was a deadly threat to ordinary humans, but also allowed the capable people of Nanzhou City to bathe in the sunlight, and also blocked the mutant creatures outside the city.

Today, the human metropolis of the four regions is made up of this device.

At the center of the city is a huge energy generator and nuclear reactor, from which all the energy consumed to defend the city's energy barrier comes from nuclear fusion, which comes from the surface of the moon.

Mankind has mastered nuclear fusion technology for more than 300 years, and today it has developed into the fourth generation of nuclear fusion technology.

It is precisely because of the progress of nuclear science and technology that mankind has been able to bathe in harmless sunlight after the catastrophe.

Mu Feng wandered in the bustling crowd, and from time to time he would see some special people, their appearance always had ordinary people cast envious, respectful and awe-inspiring glances, and there was a "Wu" word on their left chest, which meant that he was a "martial artist".

The ordinary people in Nanzhou City know the strength of the warrior, but also know the terrible power of the warrior, according to legend, some super strong people can smash a skyscraper with one punch, like supermen have incredible power.

Only a powerful warrior can calmly enter and exit the forbidden area of the ruins and come back alive.

Mu Feng walked aimlessly on the long street, and then saw a young man with the word "Wu" engraved on his chest standing in front of the fruit store to buy apples.

"Boss, how do you sell apples?"

"7 yuan a catty, but you are a warrior, as long as a warrior and a soldier come to our store to buy something, all fruits in our store will be discounted by 5%."

"Oh? So good? ”

"Of course, without the protection of your powerful warriors and armies, we ordinary people will sooner or later become food for monsters."

"Protecting the people is the duty of our warriors!"

Mu Feng watched the young warrior and the fruit boss talking and laughing, becoming a martial artist is everyone's dream in their youth, all the ordinary people living in this city, they all have such a vision when they are young, or people in their youth are dreaming.

Becoming a warrior, helping the weak, and protecting the weak is what every ordinary person has dreamed of.

The young warrior swiped his card to pay the bill, then left with a bag of fruit, and quickly disappeared into the crowd. Although they have great power, even terrifying power, they do not overlook all beings from above because of this, and the fantasy plot of what is strong and weak is ant does not happen in this world.

Warriors are also people, the family of warriors may be an ordinary person, the greater the ability, the greater the responsibility, this is the creed of every warrior, they enjoy and use up most of the resources in the society to train stronger, but also the responsibility to become the guardian of the people, the people also have great respect for them, this is the environmental portrayal of the post-human civilization era.

"Brother...... I don't want to drag you down, take good care of Mom. Mu Feng suddenly murmured silently in his heart, and suddenly, he quickened his pace and walked towards the outside of the city.
