This kind of intense pain came and went quickly, and just when Duan Fei's consciousness was about to fall into complete darkness, the pain suddenly receded as quickly as a tide, and his consciousness returned to his body.

At this moment, the scene in front of Duan Fei's eyes had all changed, and what filled his entire vision was countless colorful lights, and in these intricate and intertwined lights, he saw a small sapling that was as transparent as crystal.

"What is this?" Duan Fei looked at the sapling floating in front of him with some confusion, and he didn't know what was going on for a while.

However, at this moment, there was a sharp pain in his brain, and then countless large amounts of information began to rush into his mind frantically.

From these fragments of information, he knew that the small transparent sapling in front of him was called the "Evolutionary Tree".

Regarding the source of the evolutionary tree, Duan Fei did not find relevant information for the time being, only knowing that it was the core of a very advanced civilization system......

Just when he was puzzled, the evolutionary tree suddenly shot out a white light to envelop him, and then a cold electronic voice suddenly sounded in his head:

"The evolutionary system has started, and the project of recognizing the Lord has begun!"

The moment the voice sounded, Duan Fei felt that since his body was shrouded in that white light, it was as if the whole person had been seen through in an instant, and his whole body was exposed to the air like **.

It didn't take long for only a "drop" sound to be heard, and a series of electronic sounds continued to sound.

"The genetic chains are matching!"

"The gene is matched, and it is entered into the system!"

"Confession is complete!"

After the voice disappeared, Duan Fei suddenly had a lot of things in his mind, and when he looked at the pure white evolution tree in front of him again, a feeling of blood connection suddenly welled up in his heart. After sorting out the messy information in my brain, I finally have a certain understanding of the role of the evolutionary tree in front of me.

It turns out that the evolutionary system controlled by this evolutionary tree is to help the owner to continuously improve his own genes and evolve. Of course, if you want to evolve, there is also a price, and this price is the evolution point.

There are many ways to get evolution points, but there is only one way to get evolution points provided by the evolution tree, and that is to kill the walking corpse, for each low-level walking corpse killed, he can get a point of evolution points, and with these evolution points, he can choose to strengthen his body, fighting skills, survival skills, detection ability, and so on.

The initial ability is not strong, and it can only strengthen its own physique and strength, but this is enough for Duan Fei.

At the beginning of the apocalypse, basically there were some low-level walking corpses with no intelligence running rampant outside, and there was no threat to Duan Fei at all, but with the ability to continuously strengthen all aspects of his body with the evolution point, the danger of survival has been minimized.

However, after seven days, some of the walking corpses and alien beasts will mutate. These mutated walking corpses and alien beasts, they will produce weak intelligence, more intelligent, more powerful, and even have special abilities. However, at that time, there will be a small number of people among the human race who will awaken their abilities and embark on the path of evolution. And at that time, his ability to evolve the tree will also change to a new level accordingly.

At this moment, the cold electronic voice sounded again: "Turn on the evolution system consumption, a little evolution point!" Remaining, two evolution points! Whether or not to use it. ”

After hearing this voice, Duan Fei chose "yes" directly without hesitation, when the end comes, if you can be stronger, you will have a better chance of saving your life.

Then, two options appeared in front of Duan Fei's eyes, one was to strengthen his strength, and the other was his ability to detect. Both ability upgrades require two evolution points. After thinking about it for a while, he decided to strengthen his strength. After being reborn, although Duan Fei retained the combat skills and experience of his previous life, this body is still too weak for him now, and the improvement of strength is the most important thing.

"Doubled the strength, consume two evolution points, remaining, zero points, the system is closed!" At the moment when he chose to be sure, an electronic voice suddenly sounded, and then the scene in front of him quickly became blurred, and in the confusion, it seemed that a huge force had brutally withdrawn Duan Fei from the system, and the next moment, the consciousness returned to his body again.

……

Duan Fei slowly opened his eyes, and a familiar scene appeared in front of him again. He found that he was lying on the bed at the moment, Duan Xinyue was sitting on the side, her head resting on his chest, and she seemed to be asleep.

Duan Fei moved his body slightly, his movements were very careful, but he still woke Duan Xinyue up.

Duan Xinyue raised her head violently, and when she saw that Duan Fei had already sat up, a happy smile immediately appeared on her face.

"Brother, you finally woke up, I was almost scared to death by you!" Duan Xinyue slammed Duan Fei's chest, and the smile on her face looked heartless.

However, Duan Fei noticed her eyes that were a little red, and knew in his heart that she had cried when he was unconscious. Seeing her like this, Duan Fei felt a pain in his heart, stretched out his right hand, and directly hugged Duan Xinyue into his arms.

Duan Fei's movements startled her, but Duan Xinyue didn't struggle, and the whole person was completely lying on his chest, quiet like a kitten.

"I just fell asleep from being too tired, and it's fine. Don't worry, I won't leave you! Duan Fei touched her head and comforted.

"Hmm!" Duan Xinyue nodded, raised her head and asked, "What should we do now, this food is enough for us to last for a while, should we stay here and wait for the army's rescue?"

Duan Fei looked at her and shook his head slowly.

The end has come, and the whole world has been thrown into chaos. Although the army is an extremely large force for humanity in the late apocalypse, at this time, the army is also in chaos, and there is no time to take care of them. And when the army stabilized, it was seven days later, and at that time, the world changed earth-shatteringly.

"How can the army have time to care about us, now we can only rely on ourselves!" Duan Fei stared at her eyes and said, "But you don't have to worry, as long as I am here, we will definitely be able to live, and I will not let you be hurt at all!"

"I believe in you!" Duan Xinyue looked at Duan Fei quietly, with a flash of crystal in her eyes.

"You can sleep first!" Looking at Duan Xinyue's haggard face, Duan Fei sighed, took out a quilt from the room, and gently covered her......

"I can't sleep!" Duan Xinyue shook her head.

She thinks that her psychological quality is very strong, no cockroach and mouse can scare her, and her independent life since she was a child makes her feel that no matter what difficulties she encounters, she can face them with a smile.

But now it's different, it's the end of the world.

When she thought that the world she was familiar with had become history, and that she would inevitably fight those terrifying walking corpses in the days to come, she shuddered in her heart.

When a normal person encounters this situation, let alone sleeping, I am afraid that at this moment, there are already six gods and no masters, and they are basically about to have a mental breakdown. Duan Xinyue was able to maintain her composure, which was already very good.

"Sleep, if you want to live, you must learn how to rest and conserve your physical strength!" Duan Fei sighed and comforted.

After hearing Duan Fei's words, Duan Xinyue was silent for a moment and nodded.

"You have to stay by my side, and you are not allowed to leave half a step!" Duan Xinyue held my hand tightly, and her eyes were full of nervousness.

"Don't worry, I won't go!" Duan Fei patted her hand and said.

Hearing Duan Fei's words, Duan Xinyue seemed to have found spiritual sustenance, smiled slightly, and then slowly climbed onto the bed, covered the quilt and fell asleep.

Duan Fei sat quietly beside her and waited until she fell asleep before slowly getting up and coming to the window.

It was already three o'clock in the morning, and a hazy light had begun to glow in the sky, and the air was filled with a strong smell of blood and decay.

Duan Fei quietly looked at the streets and communities outside, and as far as the eye could see, there were large patches of blood in various places in the streets of the community, like roses in full bloom. On the streets, there are still a few walking corpses wandering back and forth at the moment.

The walking corpses of later generations are extremely powerful, not only possessing great strength and various special abilities, but also their high intelligence is terrifying. These walking corpses will act in an organized manner, know how to stratagem, and can design traps, which is simply impossible to guard against.

However, the walking corpses at the beginning of the apocalypse are much weaker. They have no intelligence, and the only thing left in their brains is the desire to eat, and apart from the fact that their strength and speed are a little stronger than ordinary people, they are no different from beasts at all.

At this stage, the walking corpse, the virus is just blindly invading their bodies. Walking corpses like this have suffered devastating damage to most of the body's functions.

They are afraid of the sun, and the ultraviolet rays from the sunlight can weaken their eyesight and slow down their movements, so during the day, the walking corpses rarely move outside, and at this time, it is also when they are at their weakest.

For humans, after becoming a walking corpse, their body is actually dead. They are able to act because the virus takes control of the nerve centers of their brains.

So if you want to take out the walking corpse, a headshot is the most concise and effective method.

However, they are particularly sensitive to taste and sound. So when you are outside, you must be careful to make sure you don't get any small wounds. Because as long as the slightest smell of blood appears, it is possible to attract them.

Although one or two walking corpses may still be able to deal with, but ten hundreds, hundreds, thousands, without the awakening ability, the absolute number is suppressed, and no one can survive at all.

Of course, for Duan Fei, with a good understanding of their weaknesses, these low-level walking corpses in the early stage were not enough, they were just one evolution point after another.

The most important thing for Duan Fei at present is to take advantage of this short seven-day period to strengthen himself as much as possible. After seven days, if he doesn't have the ability to awaken, then he must hunt down those mutated walking corpses to obtain the genetic nucleus in their bodies and become an awakened one.

At that point, he must have the strength to be able to stand up to the mutated walking corpses, so in the seven days before evolution begins, he must do everything possible to strengthen himself.

God created the world in seven days. And the virus took seven days to complete a thorough evolution of all living things in the world and enter a new era.

On the evening of December 21, 2016, the end broke out!

In the early morning of December 22, 2016, Duan Fei stood above the ruined city, looking down at the land, and quietly clenched his fists.
