This time, he has been tempered by tribulation and has achieved a true indestructible body of Vajra. The tiger down the mountain is no longer his opponent.

Xu Yuntian knew why Principal Fang was afraid of the tiger in the mountains. Because the tiger in the mountains had a hot temper, he would hit someone if he had disagreements, and even killed you. Therefore, most people dare not provoke the tiger in the mountains.

According to logic, President Fang could not know that the man Xiashanhu came to Blue and White University to perform a mission. He saw the scene of the man Xiashanhu beating people with his own eyes.

That method was much more cruel than Xu Yuntian. He pulled the man's arm off on the spot and grabbed a rib. The scene was so bloody that Principal Fang was still terrified.

Just as Xu Yuntian was talking to Principal Fang, Yan Xiaoyu had already knocked down all the subordinates brought by Lao Jin, and Lao Jin was stunned at the time.

He didn't expect that a security guard standing guard at the gate of Blue and White University would knock down the masters around him. He glared at Yan Xiaoyu and said, "Who are you?"

"I'm just a little security guard!" Yan Xiaoyu said as he came to Lao Jin and grabbed his collar.

Lao Jin looked a little panicked, but he tried his best to pretend to be calm and said, "Boy! If you dare to touch me, my brother-in-law will peel off your skin!"

"I'll go! I'll touch you! Wait for your brother-in-law to skin me!" Yan Xiaoyu sneered and punched Lao Jin in the nose.

Lao Jin was knocked away, his nose bridge was broken, and his nose bleeding spurted out, and he fell to the ground.

Lying on the ground, covering his nose, Lao Jin stared at Yan Xiaoyu and said viciously, "Boy! You dare to hit me! You are waiting for my brother-in-law to skin you!"

After saying that, he turned his head and looked at Xu Yuntian and said, "Boy! And you! My brother-in-law will also break the bones!"

"Yes! In order to make your brother-in-law cause trouble for me, I must leave some souvenirs for you, otherwise your brother-in-law will not be angry." Xu Yuntian sneered in front of Lao Jin.

He raised his feet and gently stepped on Lao Jin's ankle. With a click, Lao Jin's ankle shattered, causing him to scream like a pig.

"Hehe! Go and tell your brother-in-law! I, Xu Yuntian, waited for him to break my bones!" Xu Yuntian said with a smile.

When Lao Jin saw Xu Yuntian's indifferent expression, he didn't dare to curse anymore, and cursed in his heart, "You are waiting for my brother-in-law's anger! You regret offending me, Lao Jin!"

Lao Jin's subordinates supported Lao Jin and left in a mess. President Fang smiled bitterly. He looked at Xu Yuntian and Yan Xiaoyu and shook his head secretly and said, "Hey! These two troublemakers! When the tigers come down the mountain, Blue and White University may be uneasy."

Xu Yuntian patted Principal Fang and smiled and said, "Principal Fang, don't worry about us. You know our methods. Just a tiger down the mountain, I want him to become a bug down the mountain!"

Principal Fang remembered Xu Yuntian's power, and he couldn't help but laugh and said, "Hehe! Yes, with you here, there is nothing scary about going down the mountain tiger."

But he secretly cried in his heart, "You are making trouble at Blue and White University, and the most unlucky thing is me, the principal! I am afraid the position of the principal cannot be saved! Alas..."

At 5:30 pm, Xu Yuntian was in the laboratory of the Institute of Biology and was watching Pan Ziyu's genetic research results.

Recently, Pan Ziyu has developed a new gene fusion breed, one or two, the first type is a frog pig. This pig looks like a frog, has no hair on its body, and can live in the water and on the shore.

Another breed is chicken and sheep. This goat looks like a chicken, four legs, white hair, and can lay eggs.

The egg laid is very big, the size of a basketball. After the egg is hatched, it is the little boy of the chicken and sheep.

When Xu Yuntian saw these two new varieties, he said with great satisfaction, "Well! Ziyu, you have developed these two varieties in such a short time. It seems that you have a deep attainment in the integration of gene fusion technology."

"Yuntian, I have a bold idea. I wonder if I can study it?" Pan Ziyu looked at Xu Yuntiandao.

"What are the bold ideas?" Xu Yuntian looked at Pan Ziyu and said.

"I want to fuse the regeneration gene of the gecko's tail into the human embryo. If the fetus with this regeneration gene will be damaged in the future, such as if the finger is broken, it can be regenerated." Pan Ziyu looked at Xu Yuntiandao.

"Uh! Although this idea is very good and bold, it will change human genes. If it causes gene mutations, it will be troublesome. I don't agree with you doing this." Xu Yuntian shook his head and said.

He knew very well that the mercenary alliances abroad were secretly studying the experiment of moving fusion animal gene mutations, and developed many mutated psychics.

However, this kind of mutant psychic has a big disadvantage, which is that it will become very bloodthirsty or cruel if it inherits the cruelty of animals.

Xu Yuntian was worried about genetic mutation. Although the probability of this mutation was not high, once it mutated, it would cause serious consequences.

"I think if the control is good and the gene brushing is strictly selected, there will basically be no genetic mutation." Pan Ziyu looked at Xu Yuntian and said confidently.

Xu Yuntian still shook his head and said, "No! You must not do this. There are many unstable factors in animal genes. Never do this kind of experiment."

Seeing Xu Yuntian so firm, Pan Ziyu shook her head and said, "Okay, I'll give up this experiment."

Xu Yuntian saw that Pan Ziyu said that giving up was a perfunctory answer, and it might be a sneaky experiment in the future. He just continued to persuade Pan Ziyu, and suddenly a shout came from outside, "Xu Yuntian!"

Listening to the voice of Principal Fang, Xu Yuntian hurriedly walked to the window, looked down, and saw Principal Fang standing downstairs.

"Uh! Principal Fang, why are you here to find me again?" Xu Yuntian said with some dissatisfaction.

"Teacher Xu, Yuan Zhenwu, the tiger down the mountain, came to Blue and White University. He was at the gate of Blue and White University, and asked you to see him by name!" President Fang looked at Xu Yuntian and frowned.

"I'll go! The tiger descended to the door so soon!" Xu Yuntian said in surprise.

"Okay, then I'll go to the school gate to see him right away!" Xu Yuntian said to Principal Fang.

A figure flashed, and Xu Yuntian arrived downstairs and appeared beside Principal Fang.

Xu Yuntian followed Principal Fang to the gate of Blue and White University, and saw a green off-road vehicle parked at the gate of the school, and a man in his thirties was sitting on the hood.

The man had dark skin, strong muscles, scars on his face and scars on his arms. He looked like he was walking out of the rain of bullets.

This man is Yuan Zhenwu, nicknamed Xiashanhu. He is the one who once caused headaches from major mercenary alliances. The bounty once reached one billion.

But later Xu Yuntian overshadowed him. Now the major mercenary alliances have basically never heard of the title of "Down Mountain Tiger", because Yuan Zhenwu was seriously injured while performing a mission and faded out after he recovered.

Xu Yuntian looked at Yuan Zhenwu and walked slowly towards him. He stopped about two meters away from Yuan Zhenwu.
