After the protective cover broke, Buchuan's bark panicked. He hurriedly used the protective cover again, but he smelled the scent of Demon One.

As long as you smell it, you will be infected. This is the horror of Demon 1 virus. Buchuan's bark's face changed. He knew that if he was infected, he would definitely die.

"Ghost Sadness! I'll fight you!" Buchuan's bark roared angrily, his hands closed, and a powerful energy was released.

The powerful energy hit the space wall like a spear, and the space wall shattered.

Seeing that the energy was about to hit the barrier interface, Buchuan Tree Bark suddenly felt weak all over. Demon 1 virus was on him, and his skin began to turn black and fester.

Buchuan's bark screamed in terror. He looked at his hands that had turned black and began to ulcerate, and said tremblingly: "Oh! I'm infected!"

Xu Yuntian looked at Buchuan's bark and said coldly: "You are taking it upon yourself, using this vicious demon No. 1 to harm others! This is the retribution to you!"

Buchuan's bark felt pain all over his body. He rolled all over the ground and howled. His skin began to ulcerate, and his hands couldn't help but grab it wildly.

The skin fell down in large pieces, and the bark of Buchuan instantly turned into a broiler with plucked hair, twisting on the ground like a cut-off earthworm.

The scenes of those infected with the Demon Virus were so terrifying. Xu Yuntian frowned slightly. He shook his head and threw out five incendiary bombs.

The laboratory immediately burned, and the Demon 1 virus could only be extinct at high temperature. Under the high temperature, the Demon 1 virus could not survive and was all killed.

After the laboratory caught fire, the laboratory's security system immediately issued an alarm. Xu Yuntianxun threw out several remote-controlled bombs and then left the laboratory.

After hearing the alarm, the security guard ran towards the laboratory. Xu Yuntianxun used his disguise ability and turned into the bark of Buchuan.

The security guards saw Buchuan's bark and hurriedly said, "Lord Buchuan, what's wrong with you?"

"The laboratory accidentally caught fire, you go and put out the fire!" Xu Yuntian said to the security guards.

The security guards immediately rushed towards the laboratory. When they entered the laboratory, Xu Yuntian showed a sneer on his lips and pressed the remote control.

I heard a few loud bangs, and a bomb exploded in the laboratory. The bomb was very powerful and the entire laboratory began to collapse.

Xu Yuntian calmly arrived at the elevator door. He pressed the elevator door, pressed the button, and the elevator rose quickly.

After a while, Xu Yuntian arrived at the first floor, he got out of the elevator and walked towards the office building.

A moment later, Xu Yuntian arrived on the 19th floor of the office building, where the office of Buchuanlin, the general manager of Black Bee Group, was here.

At this moment, Buchuan Lin had just answered the phone and learned that the underground laboratory had been blown up, he was shocked and angry.

"Oh! What's going on? Who blew up the underground laboratory?" Buchuan Lin said in shock.

At this moment, Xu Yuntian appeared in Buchuanlin's office. When he saw Xu Yuntian, he said in surprise: "Buchuan Bark, what happened to the laboratory?"

"Oh! It's nothing! I've blown up the laboratory!" Xu Yuntian looked at Buchuanlin and said with a smile.

Buchuan Lin looked at Xu Yuntian with shock and said, "Buchuan tree bark, you are crazy! Why did you destroy the laboratory? That's our three years of hard work!"

"Demon 1 virus is too vicious. We cannot let these viruses flow out, otherwise I will feel uneasy." Xu Yuntian looked at Buchuan Lin and said with a smile.

Buchuanlin looked at Xu Yuntian, and he stared at Xu Yuntian and said, "You are not Buchuan tree bark, who are you?"

Because Demon No. 1 was proposed to study by Buchuan Tree Bark, Buchuan Tree Bark is a cruel, insidious and cunning person, and it is impossible to do so. Therefore, Buchuan Lin realized that the person in front of him was definitely not Buchuan Tree Bark.

"Hehe! You are still quite smart, yes, I'm not Buchuan's bark!" Xu Yuntian smiled and returned to his original appearance.

When Buchuanlin saw Xu Yuntian's face, he immediately recognized Xu Yuntian and said in shock: "Ghost sees sorrow!"

"Hehe! I didn't expect it! I heard that you are an elite disciple of the Buchuan family! Is this true?" Xu Yuntian looked at Buchuan Lin and said with a smile.

Buchuan Lin was very excited. He knew that Gui Jianchou was powerful, and that he was the person who destroyed the headquarters of the Black Snake Mercenary Alliance, which was known as the world's number one defense.

Buchuan Lin stabilized his emotions and looked at Xu Yuntian and said, "Yes, I am an elite disciple of the Buchuan family!"

"Oh! Since I am an elite disciple of the Buchuan family, I will test you. If you can answer, I will let you go!" Xu Yuntian looked at Buchuanlin and said with a smile.

"Oh! You want to take the exam to test me! OK! I am a top student at Haas University, and I also received a Haas University Mathematics Scholarship!" Buchuanlin looked at Xu Yuntian and said disdainfully.

"Oh! You also received a Mathematics Scholarship for Haas University! Then I'll give you a math problem!" Xu Yuntian said with a smile.

Then Xu Yuntian picked up the pen and paper on the table, wrote a math problem on the paper, and handed it to Buchuan Lin and said, "Just this question, this is an ancient math problem. How do you think of it?"

Buchuan Lin took the paper and pen, and he looked at the math problem, but at first he was still disdainful, and then frowned.

About five minutes later, Buchuan Lin's forehead was sweating and his hands holding the pen began to tremble.

"Buchuan Lin, don't you say you are an elite child of the Buchuan family? Don't you say you are a top student at Haas University? Five minutes have passed, but you can't do it at all?" Xu Yuntian looked at Buchuan Lin and laughed.

"Let me think about it again! This math problem doesn't seem difficult! I can definitely do it." Buchuan Lin frowned.

"Oh! Then I'll give you another ten minutes! If you can't make it in ten minutes, then you can jump off this building!" Xu Yuntian looked at Buchuanlin and said coldly.

Buchuan Lin stared at the math problem. While he was thinking, his hand quietly reached into the drawer and grabbed the gun inside the drawer.

He couldn't do this math problem at all. He just said that he could do it, but in fact he was delaying the time. He wanted to kill Xu Yuntian while Xu Yuntian was not paying attention.

Xu Yuntian showed a sneer on his lips. Although Buchuan Lin's actions were hidden, they did not escape his eyes.

When a person moves, his shoulders will definitely move, which cannot escape Xu Yuntian's observation.

"There are five minutes left, hurry up! If you can't do it, you just jump off the building!" Xu Yuntian looked at Buchuanlin and said coldly.

Buchuanlin's hand holding the pen suddenly raised up, and threw the pen towards Xu Yuntian. Then, the hand holding the gun was about to shoot at Xu Yuntian.

Xu Yuntian grabbed the pen, shook his hand, and the pen flew out, just hitting Buchuan Lin's wrist with the gun.

With a sniffle, the pen tip was completely penetrated into Buchuan Lin's wrist. He screamed and the gun in his hand fell down.
