Africa is the most magical region outside of China.

There are mountains and rivers, deserts and grasslands, and tropical rainforests with beautiful scenery but full of dangers.

In an unknown tropical rainforest, a naked~ topless Caucasian man was lying quietly on the fallen leaves that were blistered. I don't feel the disgusting smell of rot emanating from my surroundings.

Not far in front of him, a huge crocodile with a body length of six or seven meters was lying on its stomach and feeding. This crocodile is the bay crocodile, currently the largest crocodile in the world, and of course, the largest if you don't count the dinosaur crocodile, which became extinct in the Cretaceous period.

The bay crocodile is a saltwater crocodile, which should have appeared in Australia, as for why it appeared in the rainforests of Africa, this man didn't know, he only knew that he didn't have any weapons, he didn't have any equipment, but he wanted to kill the behemoth in front of him.

Five minutes passed, and the crocodile was still unhurriedly devouring a baboon that had been caught by it because it was thirsty and had come to the river to drink, its sharp fangs covered with blood and minced flesh. The man lay motionless less than ten meters away from him, holding a sharp wooden thorn as a weapon in his hand, ready to wait for the opportunity to move.

Another five minutes passed, and the crocodile had finally finished its lunch, and instead of returning to the river, it looked around vigilantly, and suddenly, its eyes stopped where the man was lying on his stomach.

The crocodile has a very keen sense of smell and vision, and despite the rotting smell of rotting leaves and the stench of animal carcasses, it smells a hint of something unusual.

Looking at the crocodile that was constantly approaching him, the man's eyes were still very calm, lying there and holding his breath, until the crocodile was less than three meters away from him, and suddenly burst out, the speed was comparable to a bullet out of the chamber.

Don't look at the huge size of the bay crocodile, but its reaction speed is really not slow, the moment the man sprang out, it also sensed the danger, tilted its head, and the barbed tail pulled towards the man.

Seeing the crocodile counterattack, the man grabbed its tail by the way, stabilized the landing point in the air, and when it fell, he rode directly on the crocodile's back as if it was wearing steel armor.

Without hesitation, the sharp wooden thorns fell, stabbing straight at the crocodile's head, but the scales of the crocodile's body were extremely hard, and the wooden thorns broke in the middle after making a crisp sound, without hurting it at all.

The attacked crocodile got angry, and with a twist of its huge body, it wanted to throw off the man riding on it, but the man left its body first.

With the strength of the crocodile's turnover, he landed in front of the crocodile with a somersault, and the remaining half of the wooden thorn in his hand was now a wooden stick.

The half-cut stick quickly pierced the crocodile's eyes, which were its most vulnerable places except for the belly.

But the crocodile reacted so fast that as soon as the stick fell, it pounced, and its big bloody mouth bit down on the man's raised arm.

The bite force of a crocodile is quite terrifying, an ordinary crocodile can reach nearly six tons of bite, not to mention the bay crocodile, which is currently the largest crocodile in the world. One can imagine what would happen if an arm made of meat would be bitten by a crocodile.

However, a miracle happened, the man's arm was bitten by a crocodile, and blood suddenly overflowed, but the arm was not bitten off.

After letting out a hoarse cry of pain, the man tried to pull out his arm, but was bitten by the crocodile, so he screamed angrily, and his other arm suddenly raised, and his fist smashed down against the crocodile's fangs.

"Bang!"

There was a muffled sound, and the man's fist was dripping with blood, but the crocodile was no better, and the sharp fangs like a small dagger were smashed down by the man's punch, and it let out a cry of pain, and the mouth that bit the man's arm was released.

Ignoring the continuous bleeding from his arm, the man picked up the fangs that he smashed down, and with a loud shout, he pierced into the crocodile's eyes.

After piercing the left eye and piercing the right eye, the crocodile, which had lost sight, continued to roll under the pain, and the soft flesh under the belly was exposed.

Taking advantage of the crocodile's belly, the man pounced, and the fangs pierced into the crocodile's belly again and again, and after a while, the blood was stained on his body, and the crocodile gradually stopped struggling.

"Whew-"

The man let out a long breath, rested on the crocodile for a long time before standing up, looked at his bloody arm, walked to the river to wash it, only to find that there was nothing serious, only the skin was pierced. Although the blood flowed a little more, it could only be regarded as a skin injury.

In a tent made of wooden planks and camouflage nets, Zheng Wuming stared at the monitor in front of him, his eyes full of excitement.

"Boss, test Specimen 224 has been tested, and the data shows that all the functions of his body are normal." A middle-aged blonde man in a white coat looked at Zheng Wuming and said.

"Okay, great." Zheng Wuming was a little excited and asked. "How many more are waiting to be experimented?"

"And eight." The middle-aged man thought for a moment and said. "Boss, are we going to continue testing? Twenty-seven people have now successfully completed the trial. ”

"Go on, of course." Zheng Wuming said without hesitation. "Thirty people, you have to help me get thirty people."

"I do my best." The middle-aged man nodded, but his eyes were a little helpless.

This is not an experiment, this is completely killing people, although this drug is very powerful, it can improve the function of the human body more than ten times, but the side effects are too great. With this drug, you either die directly or die in the jungle because your body does not function as expected. In just over half a month, as many as 200 people participated in the experiment, and only 27 succeeded -- he regretted accepting the project, but he still accepted it despite the huge reward of 10 million US dollars.

"You say, what will happen if you overuse twice the dose?" Zheng Wuming asked suddenly.

"Twice? That's impossible. The middle-aged man shook his head repeatedly. Boss, the side effects of this drug are too great, and it is unstable, if you use twice the dose, I am afraid that it will be difficult for the rest of the people to survive. ”

"So it was decided." Zheng Wuming didn't listen to his explanation, and said in a resolute tone. "The rest of the people, all of them use twice the dose."

"Boss, this won't work-"

"Shut up, you just have to do your thing." Zheng Wuming shouted coldly, and then, a cold light flashed in his eyes. "Yan Murong, when I'm ready, I'll let you return everything you took from me."
