Genetic evolutionary people have a normal IQ, and their physical strength continues to improve with genetic evolution, and their strength is stronger than those humans who have become ordinary monsters.

The higher the IQ of an individual, the lower the probability of the presence of "gene inhibitory enzymes" in the body.

A group of highly intelligent organisms like humans, who have their own "gene inhibitory enzymes" in their bodies, are the lucky ones who become genetically evolved, with a probability of less than 1 in 10,000.

Yiyun is not one in 10,000, he is only one of the human beings who maintain his own unchanged after the Cretaceous gene mutation, and he is still an ordinary person.

In the next apocalypse caused by the unlocking of Cretaceous genes, the fate of ordinary people is the worst, at the bottom of the entire biological chain, not only killing each other, but also being bullied by genetic evolutionaries with crushing strength at will, and at the same time may be devoured by other monsters at any time.

In the coming end times, how miserable the lives of ordinary people are, Yiyun, who has already experienced it once, has a deep understanding.

Fortunately, with the research of scientists in the last days, it has been found that this "gene inhibitory enzyme" can be transferred, as long as this enzyme is extracted from the biological mother with "gene inhibitory enzyme", and then transferred by injection, it can become a transgenic gene evolutionary, and at the same time has the ability characteristics of the mother after the Cretaceous gene is unlocked.

The more stable the "gene inhibitory enzyme", the more perfect the Cretaceous gene unlocking of the gene evolutionary will be, and the stronger it will be.

The degree of stability of the "gene inhibitory enzyme" depends on the degree of similarity between the parent organism and the Cretaceous organisms.

In Yiyun's cognition, this bay crocodile of Tangdu Hotel, after the Cretaceous gene is unlocked, not only has a "gene inhibitory enzyme" in the body, but also a very stable "gene inhibitory enzyme"!

He also knew that due to the very stable "gene inhibiting enzymes" in the body, this bay crocodile grew steadily after the Cretaceous gene was unlocked, and its physical strength was greatly enhanced, reaching a length of several tens of meters! The most terrifying thing was that the intelligence of this bay crocodile was also improved at the same time. In the last days, it is the absolute overlord who occupies a radius of thousands of miles in Xijing City.

Now, Yiyun is going to kill this bay crocodile before the Cretaceous gene is unlocked. The "gene inhibitory enzyme" that extracts it is then injected into its body to make itself a transgene evolutionary.

"What are you doing!"

The security guards had already chased after him, and a man who looked like a hall manager was walking towards him with a frown, and a few people who were registering their information. Puzzled, he looked here.

Yi Yun quickly took out a pair of vices from the bag behind him, twisted a large hole in the golden cage in front of him in a few clicks, and then in the midst of everyone's exclamations, he stepped into the golden cage and jumped into the marble pool where the bay crocodile was kept in captivity.

Inside the golden cage is a pool made of dark cyan terrazzo bricks, and there is not much furnishings in it, only a piece of black dead wood in the middle.

Yiyun got into the cage and jumped down, and the whole person fell about a meter in an oblique parabola. He stretched out his arms, and the cortical membrane under his flanks tensed, like a dexterous flying squirrel, and his descent slowed sharply, and then he made a smooth arc forward, and landed on the dead wood in the middle of the pool.

The bay crocodile in captivity at Tangdu Hotel is now the world's largest crocodile, with a length of six meters and a weight of more than one ton, which has always been an important gimmick for the hotel to publicize to the outside world.

Yiyun stood on the dead wood. Looking around, the pool where the captive bay crocodile is kept is a circle about 12 meters in diameter, and the water in the pond is not deep in order to better display the bay crocodile. Less than half a meter. Directly opposite the dead wood was a large, dark and deep hole, which was the nest of the bay crocodile.

"Hey, hey, stop!"

The hall manager saw Yiyun rushing towards the bay crocodile cage, thinking that some kind of troubled animal protector had come here to make trouble, and then saw that Yiyun had directly twisted the golden cage and jumped into the bay crocodile pool without stopping for the slightest, and he immediately panicked.

This man is a psychopath!

The depth of the crocodile pool is eight meters, so jump down. If you don't die, you have to break a bone, not to mention that very fierce bay crocodile down there! Such an act is completely looking for death!

"Ahh

The security guards who chased in, the people who were registering in the hall, and some staff members all rushed towards the bay crocodile cage.

Yiyun stood on the dead wood and looked around, there was no sign of the bay crocodile in the pool, and the water in the pool was swinging in a circle due to the shock of his jumping on the dead wood.

The bay crocodile's territorial awareness is very strong, and it is impossible for it not to know that the pool is so shallow, and it is impossible to hide, so the location of the bay crocodile can only be that big hole.

"You...... What are you doing......" The hall manager ran to the iron cage in a panic, and was surprised to find that the person who jumped into the bay crocodile pool was standing on the dead wood unscathed, he couldn't help but breathe a sigh of relief, but his face had turned pale, and his voice was a little trembling.

Other people also gathered around at this time, some good deeds, raised their mobile phones to take pictures and record short videos.

"Come up!" The security guards, who were also frightened, rushed over and shouted at Yiyun, and one of them quickly threw down a rope: "Hey! Hurry!"

Unaffected by these people, Yiyun took out two thumb-thick chains from his backpack, quickly wrapped them around his arms, and then walked towards the Bay Crocodile Cave step by step.

"What does he want to do!"

The hall manager and the security guards were at a loss, and the rest of the people were noisy.

Yiyun stared at the Bay Crocodile Cave, and those noisy voices were all put behind his ears.

The base sent him back here through the energy block, and the strong physique he had cultivated in the last days had been restored to his pre-Cretaceous genetic mutation state when he traveled through the flow of time, and his current body was that of an otaku who had been facing computers for a long time, and Yiyun's only advantage against this bay crocodile was his mind.

There was a lot of noise all around, screams, shouts...... One after another, but Yiyun concentrated, but it seemed to be in a silent atmosphere. The "ticking" sound of a drop of water falling from a dead tree into the surface of the pond water is clear to your ears.

"Whoa!"

A fishy smell rushed towards him, and the people surrounding the golden cage let out a neat exclamation: "Ah!"

A huge crocodile six meters long and the size of a small truck suddenly rushed out of the big black hole, and Yiyun's position was less than five meters away from the entrance of the hole.

The noisy voices of the people stopped abruptly after that exclamation, but the silent atmosphere that Yiyun was in after adjusting his mind was suddenly broken, and all kinds of sounds roared, a puff of water droplets shot at him, and the low roar of the bay crocodile, the sound of its tail flicking, all rang out at the same time.
