The development of second-order genetic modification fluids still requires original evolutionary cells.

Because the first-order genetic modification fluid developed by Su Yu eliminated 90% of the evolutionary ability of the evolutionary cells, the evolutionary ability of the evolutionary cells was too strong, which led to the evolutionary cells absorbing too much energy too quickly, so that the mitochondria of organisms could not meet this level of function and caused the cells to lose their nutrients and die.

Therefore, the second-order genetic modification fluid needs to enhance evolutionary ability. Similarly, this will also enhance energy consumption. However, Su Yu has prepared a high-concentration nutrient solution, so he has no shortage of energy.

But this degree must be grasped well, not too little, as it will not be able to surpass the limits of the human body.

You can't have too much, as it will cause you to lose a lot of nutrients and die.

This requires experimentation.

The super fighting cock came in handy again. Su Yu went to the farm again, and then used his hair and fertilized eggs to cultivate a large number of super fighting cocks. After bred these super fighting cocks to the peak of their chicken birth, he then used second-order genetic modification liquid to transform their bodies to see if they could break through the individual limits.

This was destined to be another long experiment. Su Yu touched his hair and said, "I am really worried about my hair. I won't be stronger and bald, right?"

Biological experiments, Su Yu was good at it, so he immediately started to take action, began to cultivate generations of super fighting cocks, and used second-order genetic modification liquid to experiment on them.

But the results are not ideal. The mortality rate of first-order genetic modification is 60%, and the mortality rate of second-order genetic modification is 100%. This will consume a large amount of experimental subjects and a large amount of... hair!

This is so bad, Su Yu really feels like he is going to be bald.

After almost 100,000 failures, Su Yu finally realized that it seemed impossible to continue like this.

"Can't the limit of egg animals be the limit of individuals? Their brain is not very developed, so they cannot break through individuals?"

After careful consideration, Su Yu began to use crocodiles and eagles to perform experiments. Both of them are egg-borne creatures, and their combat effectiveness is much stronger than that of chickens. The only trouble is that the reproduction speed is too slow and it is not easy to tame.

Once these two creatures evolve to the individual limit, it is really difficult for Su Yu to subdue them.

Everyone is the limit of individuals, which means standing on the same starting line. Why are humans necessarily stronger than other creatures?

Fortunately, Su Yu can use weapons, so he can barely subdue these two violent creatures and start the experiment.

But the result is still not good, the success rate is still 0%!

After evolution, these two organisms can also detect "amyloid precursor proteins" in their brains, but the number is too small. There are only a few hundred chickens, thousands of crocodiles, and the most are eagles, but only more than 10,000.

It seems that the degree of brain development determines the number of "amyloid precursor proteins".

After a long period of experiments, thinking and learning, Su Yu's brain seems to be further developed, and his "amyloid precursor protein" has reached more than 70,000.

"Although my body has reached the limit of individuals, my brain seems to have not reached its limit yet!" Su Yu began to think about it.

But at present, Su Yu has no new experimental subjects, so he can only use egg creatures to conduct experiments, because only egg creatures can escape with the help of fertilized eggs, but the brain development level of egg creatures is really not enough.

Sure enough, it is essentially different from the fetal organisms cultivated in the mother's body.

What should I do?

Su Yu was in trouble again.

There was no choice but to go to the zoo alone to observe the botanical garden. As the saying goes, stones from other mountains can be used to polish jade. Su Yu walked to a dead end and could only find other roads.

Unfortunately, this jade is not that easy to attack.

Su Yu found nothing and couldn't think of anything in his mind.

In the end, Su Yu just stood on a rockery, watching the still monkeys and the still tourists outside.

At this moment, Su Yu actually felt that he was not a human. He looked at the group of monkeys and the group of humans, as if he felt that they were the same kind, and he was out of place with them.

Su Yu realized that there was a problem with his mentality, as if he had been separated from society for too long.

He realized that he had been in this world that had been in a stop for thirty years!

Ten years, twenty years, thirty years, in the blink of an eye, he was already in his eighties.

Time passed too quickly, but fortunately the power of time was stopped, otherwise he would have been old and youth would not be there.

"Eighty years have passed like this, and I haven't even understood it." This was a rare time when Su Yu was idle, and he no longer thought about the path of evolution in his mind.

He looked at the group of humans, as if the group of humans were looking at the group of monkeys, as if the group of monkeys were looking at the group of ants.

Su Yu suddenly calmed down, and he felt that he didn't have to be so impatient for the first time.

Fortunately, he stayed in the presidential suite in a five-star hotel for one night, then went to the luxury sauna to steam the sauna, soaked in the hot springs, and had a barbecue buffet.

But he was addicted to swimming, surfing, climbing, and climbing again.

You must be happy when you are in a happy life, and don’t let the golden cup face the moon empty.

Su Yu ate meat in big mouthfuls, drank wine in big mouthfuls, drove a luxury car, and lived in a luxury house.

Is Su Yu degenerated?

He didn't, he just suppressed the initial doubt in his heart, and finally waited for that doubt to erupt!

Finally, after experiencing various fun projects around the world, he felt a burst of emptiness.

Su Yu returned to nature and experienced the beauty, harmony and tranquility of nature.

He began to live in seclusion and lived in the countryside. He worked at sunrise and rested at sunset, growing vegetables by himself, fishing by himself, and hunting by himself.

Because it stops, hunting and fishing is easy, and the vegetables grown basically do not grow.

But in the countryside, there are pigs, chickens, cattle and sheep, donkeys, mules, and...

Wait, mule?

Su Yu suddenly realized something.

When he saw the still mule, when he saw the mule pulling a millstone, he suddenly realized something.

"There is even no reproductive isolation between different species. Horses and donkeys give birth to mules, tigers and lions give birth to lions and tigers. In genetic modification, scientists can even let cabbage and purple cabbage merge into purple cabbage, which has higher nutritional value and stronger survivability!"

After falling into depravity for a few years, Su Yu suddenly felt that he had a sudden enlightenment and his mind was enlightened.

"So, can animals and animals achieve gene fusion?"

"The brain development of egg animals is not high, so what about primate genes and egg organisms fuse?"

"I have evolutionary cells. As long as I write the genes of primates into it, invade and change the genes of egg organisms, I can create...gene fusion organisms!"

Su Yu suddenly had an idea in his brain. He planned to become the creator and use gene fusion technology to create egg primates!
