It seems that during the period of coma, the evolutionary tree underwent some unusual changes without Duan Fei's knowledge, although he didn't understand what was going on, but combined with the disappearance of the source species, Duan Fei felt that there must be a special connection between the two.

Entering the evolution system again, Duan Fei found that except for the addition of one more "perfect genetic engineering", the other attributes of the body had not changed much, and the strength and agility were still level three, the detection ability was level two, and the spiritual power was level one.

Their level has not increased, but Duan Fei's strength is several times stronger than the original. Duan Fei thought to himself, this should be the ability of "perfect genetic engineering".

The first time it was activated, it changed Duan Fei's genes, removing the flaws in his genes, thus making it more perfect and better.

Everyone knows that a person's appearance, intelligence, height, and all other factors are determined by your genes. The better your genes, the better your body will be. After the "Perfect Genetic Engineering" perfected Duan Fei's genes, although Duan Fei's physical attributes did not change in all aspects, all aspects of Duan Fei's body itself have been greatly strengthened.

It's like a "cardinality" problem. China has a population of 1.3 billion and Japan has a population of 100 million, and the population of the two countries has grown by the same 3 percent, but the changes in the number of people are very different.

Duan Fei's body's original strength and other attributes became stronger, so the increase in level would naturally be infinitely magnified.

Thinking of this key point, Duan Fei's heart was suddenly filled with excitement and surprise.

If the "perfect genetic engineering" can really achieve such a function, then this thing, its ability is simply against the sky, because Duan Fei knows better than anyone else that the change of genes will definitely bring more than just the enhancement of all aspects of the body.

Genetic shackles.

The name flashed in Duan Fei's mind.

In a previous life, a strong man once exclaimed before he died: "Evolution is infinite, but individuals are limited after all!" ”

When this strong man tried to evolve for the last time, he completely collapsed because his genes could not withstand the huge impact of the evolutionary process, and finally died as a result. His death tells humanity that although evolution can go on forever, the genes of individuals have brought evolution to an end. Later, people called this defect of evolution "genetic shackles".

The reason is very simple, the strength and inferiority of each organism's genes determine how far it can evolve. If the genes are inferior, then you may only evolve once or twice, and then you will never stop, and if the genes are excellent, then you will have the opportunity to become a peerless powerhouse.

Thinking of this, Duan Fei's heart "plopped" and jumped violently.

If this is the case, then this "perfect genetic engineering" can break the genetic shackles, and without the genetic shackles, Duan Fei can continue to evolve, and even have the possibility of surpassing the S-level awakened.

At this moment, Duan Fei suddenly had a feeling of being hit by happiness.

In the past life, how many strong people have spent their lives looking for ways to break through the shackles of genes, and all the final results are failures. However, Duan Fei has the general existence of the evolutionary tree, as long as he spends a little evolutionary point, he can improve Duan Fei's genes infinitely, how incredible it is.

Of course, the evolution points required to start the "perfect genetic engineering" are still a little too much for Duan Fei, but it is definitely worth the price. Evolution points can be accumulated slowly, but the perfection of genes is really hard to come by.

After learning about the true ability of "perfect genetic engineering", Duan Fei's mood could not calm down for a long time. It took a long time for Duan Fei to recover from the previous shock.

At this time, there were bursts of zombie roars in my ears, and it was obvious that the battle just now had attracted some zombies to come over. Duan Fei frowned, and in order to avoid unnecessary trouble, his body shook and quickly left here.

The task of seduction is complete, and it's time to go and rendezvous with them.

Duan Fei's figure moved, and he disappeared here in the blink of an eye, and on the empty ruins, there were only headless corpses left, which seemed to tell the world that there was an absolute massacre that had just happened here.

At this time, Xia Ke and his party had successfully escaped from the neighborhood and came to the agreed intersection.

Behind a hidden corner, the group looked into the distance with apprehensive expressions, as if waiting for something.

"It's been so long, that person, nothing will happen!" At this time, Officer Li in the crowd suddenly said loudly.

As soon as the words fell, everyone's faces changed, and they all showed a trace of worry. Twenty minutes had passed, and Duan Fei hadn't appeared for a long time, which couldn't help but make everyone feel a bad feeling.

In the apocalypse, everyone's spirit is in a state of extreme tension, and in such a situation, it is easy to have many associations.

They believed that although Duan Fei's strength was very strong, he was a person after all, and it was very likely that he was already dead under the pursuit of so many zombies.

"Team Li, if you don't speak, no one will treat you as a mute!" Xia Ke frowned, and his cold gaze fell on his face like a sharp knife.

Feeling Xia Ke's murderous gaze, Officer Li's heart tightened slightly, and his voice couldn't help but be a little smaller: "But, so much time has passed!" I'm afraid something will go wrong, so let's ...... first."

"Team Lee!" Before he finished speaking, Xia Ke directly interrupted him and said coldly: "We have made an appointment to gather here, and we must keep our promise." Besides, if it weren't for him, I'm afraid we would have lost our lives a long time ago, how could we do such a thing of crossing the river and demolishing the bridge. ”

Hearing Xia Ke's words, Officer Li's face turned slightly red, revealing a hint of embarrassment.

In fact, he is indeed thinking about everyone. The outside world is extremely dangerous, and every minute they spend here is more dangerous.

Of course, there is no certainty as to who is who, and if it is really done, it is indeed a rational choice, but there is no trace of conscience.

Sensing the strange looks of the others, Officer Li lowered his head and stopped talking.

As the minutes passed, everyone became more and more anxious. When Xia Ke himself was a little shaken, that figure finally appeared in front of them.

When he saw Duan Fei's figure, Xia Ke was the first to rush over and came to Duan Fei, followed by the others.

"You're finally here, we're all scared to death!"

The others were also talking and expressing their joy in words.

"Something happened on the way!" Duan Fei smiled slightly and explained to them.

Duan Fei didn't lie to them, on the way back, Duan Fei encountered a group of zombies who were attracted by the sound. However, in order to be in a hurry, Duan Fei spent a lot of effort to get rid of them, but he also wasted a lot of time.

"Accident, nothing, right?" Hearing Duan Fei's words, a young man suddenly asked.

"It's fine!" Duan Fei said with a smile.

At this time, everyone found out that Duan Fei had no wounds at all except for some messy clothes, which was a bit incredible.

This picture fell into Xia Ke's eyes, which shocked her even more. can successfully escape under the pursuit of so many zombies, so how strong is Duan Fei's strength. If she guessed that those zombies had been killed by Duan Fei, she didn't know what kind of expression she would show.

Despite her surprise, she didn't voice her doubts. Everyone has their own secrets, not to mention a strong person like Duan Fei, Xia is not a fool, she understands some things, it is better not to say it.

"Now that everyone is here, you can hurry up and go, and I'll let Jinbao escort you to the shelter!" As he spoke, Duan Fei patted Jinbao who was standing beside him. Jinbao understood what Duan Fei meant, and let out a humanized roar at everyone.

"You're not with us?" Hearing Duan Fei's words, everyone's faces changed, and Xia Ke asked directly.

A strong person like Duan Fei, as long as he stays by their side, it is a guarantee of safety, if Duan Fei leaves, then who will protect them.

"No!" Duan Fei shook his head and said, "I said that I also have a younger sister, and now that I have been missing for three days, I don't know how she is. So I have to go back to my sister, and when I find her, I'll go to the shelter. So, I can't be with you for the time being! But Jinbao will protect you, don't worry! ”

"Are you sure you want to part with us!" Xia Ke bit his lip and confirmed again.

"Yes, I have to leave!" Duan Fei's expression was solemn.

"Alright then, don't say goodbye to Duan Fei, I'll be waiting for you in the shelter!" After hearing Duan Fei's reply, Xia Ke showed a lonely expression on his face. She didn't know why, but when she heard that Duan Fei was leaving, she suddenly felt a faint sense of loss in her heart. However, as an armed policeman, she quickly adjusted, and her face, which was always as cold as ice, showed a smile for the first time.

"My name is Xia Ke, summer of summer, cute Ke. Nice to meet you! She stretched out her right hand to Duan Fei with a charming smile on her face.

"I, my name is Ling Wenwen, thank you for saving me!" At the same time, Ling Wenwen also walked in front of Duan Fei with a red face, and looked at Duan Fei quietly, her eyes clear and bright.

Looking at their faces full of kindness, a warm current gradually surged in Duan Fei's heart.

This is called human affection, this is called human nature. In the era of the end of the law, Duan Fei had almost forgotten these terms, but he didn't expect that today, Duan Fei would think about it again.

"My name is Duan Fei!" Duan Fei stretched out his right hand and clasped it tightly with Xia Ke's hand. Then he turned around and ran off without looking back, and soon disappeared from everyone's sight.

"See you soon!" Looking at Duan Fei's disappearing figure, Xia Ke muttered to himself, a little in a trance.
