Boom!

Another rat exploded and died.

This is already the twenty-third.

The whole room was filled with a strong smell of blood, and Su Lifeng's forehead also had a layer of fine sweat.

However, his mood was still not the slightest bit agitated, and in the process of doing experiments in the past, it was common to fail hundreds of times.

It's just that he doesn't have many tools now, and everything depends on experience and visual inspection.

Cheng Xiaomei hadn't come to his senses yet, and Xiaomi took the cage to help him catch more mice.

It was only at this time that Su Lifeng learned that after the fall of the human city, the xenos had completely abandoned those smaller creatures, such as rats, bugs, and birds. But these creatures have also undergone some changes after the environmental upheaval, and they are also some troublesome existences for ordinary people.

Just like these rats, they not only eat the flesh of dead people, but even attack the living. Judging by their numbers, it is likely that there have been cases where survivors slept in their clothes at night and woke up in the morning with only skeletons left.

Compared to the group evolution of these creatures, humanity only has mutants and awakened people, but it seems to be inferior.

"Now it's also been found that the direction of evolution may be wrong......"

As the body of another mouse swelled up, and its claws made a piercing scratching sound on the iron cage, Su Lifeng's eyes couldn't help but be gloomy.

Just as he reached out to grab the blanket and was about to block it, he was somewhat surprised to find that the mouse was tightly clasping the iron cage with its claws, and the body that was about to explode kept bulging one big bag after another, and then its head flared.

"Squeak!"

In the scream, the mouse's head suddenly began to deform, the hair on its body quickly fell off, the skin began to become transparent, the red light flashed in the eyes, and at the same time, the front paws changed drastically, and a layer of flesh like pterosaur wings slowly grew.

Su Lifeng was stunned for a while, this abnormal situation was very similar to him.

But at this moment. The red light suddenly flashed from under the mouse's skin, and then there was a "bang"!

Su Lifeng slowly lowered his bone wings, looking at the flesh and blood hanging on the iron cage, but a trace of irrepressible surprise flashed in his eyes.

From the body of the mouse. He finally found his problem!

In a word, greed can't chew more.

Although he has managed to maintain a delicate balance between the three different evolutions, he has never fully reached the level of fusion.

Whether it is an astral or a xenomorph, he achieves the evolutionary effect by absorbing genes. But if two different genes don't fuse, they will definitely collapse eventually.

He had been paralyzed by a temporary balance. As a biology student, I didn't see this fatal flaw.

The rat had reached the same equilibrium as he was before the explosion, but it was only for a moment, and the end was still a physical collapse.

"The next step is to solve the problem! As long as you can find the problem, you won't have to worry about solving it! ”

In peacetime, scientists discovered a million-year-old virus, and then injected such a virus into their own bodies, and although the appearance has changed dramatically, they still forcibly maintain their physical signs in a human state through modern scientific and technological means. Looking back now, Su Lifeng feels that it was also an opportunity for human evolution, and compared to the conditions at that time, it should be more convenient for human beings to evolve now.

Su Lifeng's mind was chaotic. The hand moved quickly again.

The next mouse was licking the flesh in front of him, and when he saw Su Lifeng stretching the needle over, he suddenly stiffened, and he honestly stayed in place and didn't dare to move......

Until the sky is slightly bright......

"It's done!" Su Lifeng's mood calmed down at this time, he let out a long breath and looked at the cage in front of him that was completely empty.

There were hundreds of rats, and in the end, only one......

The rat was no longer recognizable, and it stood in a squirrel-like position, condensed to the size of an egg. The body is as white as jade, the body surface is covered with red veins, like the natural lines on jade, and the eyes are flashing like rubies. The tail on the back has turned into a large shaggy tail composed of countless red threads, and the two front paws have completely become wings, which are also full of red veins.

Despite its small size, it has a hint of danger on it. It's not F yet, but it's already.

Su Lifeng felt the same feeling as Xiaomi from it, as if it was also a part of himself. You can sense its every move.

This little thing that looked quite dangerous also showed affection for Su Lifeng, it looked down and sniffed, then flapped its wings and flew to Su Lifeng's shoulder, and then rubbed it twice.

Su Lifeng reached out and touched its head, looked at its bulging cheeks, and couldn't help but smile bitterly in his heart: "Really...... I can't fly yet, and that's unfair. ”

Seeing it hugging his fingers, Su Lifeng also had a trace of love in his heart, and thought for a while: "It's not easy for you to survive, give you a name, you can fly, and I will call you in the future...... Shuck it. ”

Su Lifeng is still very satisfied with this name, and Shu Ke obviously also has the attribute of high intelligence of the alien species, and after Su Lifeng repeated it twice, he reacted to the name Shu Ke, and flew around Su Lifeng very excitedly twice, and then went to the ground again, swallowing all the flesh and blood of the same kind.

I can't tell its small size, but its appetite is amazingly large.

"Alright, Shuk goes outside and guards, and then it's my turn." Su Lifeng said impatiently. It was about his life and death and strength, and he didn't want to wait for a moment.

Shuke's success is the result of luck, and what Su Lifeng has to do is to replicate this luck perfectly in himself. After hundreds of hands and observations, Su Lifeng felt that he had a certain certainty.

"I'm a terrestrial-level life, and my body's resilience and endurance are much stronger than those of rats, so even if something goes wrong along the way, I can hold on." Su Lifeng took out the simple tools he carried with him and began the process of "exchanging blood" for himself.

This is not really a blood exchange, but to draw out all the star power in the body first. This process was a very difficult step, in the process, Su Lifeng could almost hear the friction sound in his body, if it wasn't for the fact that he had reached the land level, he really couldn't bear the sharp pain, and he often fainted at the beginning.

But Su Lifeng used the medicine given by his mentor, and at this time, the whole person's spirit reached a very clear state and a high degree of concentration. He controlled his muscle contractions to reduce the amount of bleeding.

A small amount of blood flowed out, and a trace of viscous red fluorescent liquid flowed out along the wound and dripped into the glass bottle below.

As the star power of his whole body was gradually drained, Su Lifeng felt that his body was also weakened, and the sound of his heartbeat was amplified in his ears like a drumbeat.

"The next step is this ......"

Su Lifeng picked up another potion, he originally wanted to provide this to Cheng Xiaomei and them, but now he wanted to use it on himself.

However, as long as the pharmaceutical technology of the Ningnan Military Region can be obtained, there will naturally be no shortage of such medicines.

As the effect of the medicine began to kick in, Su Lifeng's whole body suddenly became hot, and the temperature was still rising.

Soon, he was like a boiled red shrimp, but strangely, his heart rate slowed down.

A trace of itching came out of all parts of Su Lifeng's body, and with the star power almost completely withdrawn, Su Lifeng felt that the blood vessels he had just damaged had also begun to repair.

From becoming a mutant to the present, all the life energy and genes of different kinds of organisms have become streams of heat, flowing rapidly throughout his body.

Su Lifeng suddenly had a very strange feeling, his body was now like a container that could be changed, and in the container, all the energy absorbed. In these energy centers is a fixed core......

"That's it!" Su Lifeng suddenly opened his eyes, grabbed the bottle containing star power, and then glanced at the star ring in his hand again.

He suddenly had a strong feeling that there would be a certain risk in doing so, but he missed the words now......

"Everything I feel right now comes from the instincts of terrestrial life! In cases where what you have learned is not enough to judge the risk, you should trust your instincts as a living being! Su Lifeng took a deep breath and threw the star ring into the bottle.

The star ring was silent for a moment, and then all the star power seemed to have encountered a whirlpool, and all of it was absorbed by the star ring in a flash.

Roar!

Su Lifeng suddenly heard a huge roar in his ears, which shook his head and made him dizzy, and a huge black shadow seemed to appear in front of him.

While he could barely stay awake, Su Lifeng slashed his shoulder with a knife, and then stuffed the star ring into it.

There, that's the heart of him!

It's a strange feeling, the core is like another invisible heart in the body, and maybe when you dissect it, you will find that the cells in that area are very active, but you can't see anything wrong with the naked eye.

As soon as the star ring entered, Su Lifeng suddenly felt as if his body had been hit hard by that behemoth, and a huge sense of vibration suddenly spread throughout his body.

"Hold on!" Su Lifeng gritted his teeth and didn't shout, he could feel that the star ring was colliding violently with the core. His whole mind at this time is focused on this, if this rejection reaction can pass, then, it means that his approach is not wrong, but if the rejection continues, then he must immediately take out the star ring.

One minute, one second, it could be a dead ...... (To be continued.) )
