Xu Yuntian looked at Buchuan Changku and sneered: "Your Black Snake King is dead in my hands, you want to kill me too!"

"Hmph! If you don't try, how can you know!" Buchuan Changku untied his coat and revealed his fat body.

"Uh! What are you doing? I'm not interested in the body of you, the old man!" Xu Yuntian looked at Buchuan Changku and shook his head and smiled.

Suddenly, Buchuan Changku howled, and then he made a clacking sound all over his body, gray hair grew on his body, his hands and feet discovered the change, and turned into spider feet.

Four feet grew under the ribs, and the head changed, turning into a huge spider.

"Wow! You have actually turned into a spider! Are you genetically mutated?" Xu Yuntian looked at Buchuan Changku and said in surprise.

"That's right! I'm a spider's gene mutation. I didn't inject the spider's gene mutation potion, but after being bitten by the spider, it mutated!" Buchuan Changku said proudly.

Because of being bitten by a spider, this kind of thing is one in a billion chance. This kind of mutation is a natural mutation and is much more powerful than the mutation of injecting genetic mutation potion.

"Oh! Then let's see how powerful your mutation is!" Xu Yuntian looked at Buchuan Changku and said disdainfully.

"Go to die! Slightly slim!" Buchuan Changku yelled, and white silk threads flew out of his mouth, like snow, and there was a silk screen around him in an instant.

"Wow! You can still spin silk!" Xu Yuntian said with a smile.

The white silk thread covered the sky and flew towards Xu Yuntian. Xu Yuntian calmly stretched out his palm and used the magnetic reflection ability. All the wire mesh was rejected.

Seeing that the wire mesh could not get close to Xu Yuntian, Buchuan Changku immediately roared and opened his mouth, ejecting dark green liquid, flying towards Xu Yuntian like an arrow.

Xu Yuntian still did not move. Under the magnetic reflection, the dark green poison could not approach Xu Yuntian. All fell to the ground and made a hissing sound. The cement floor was quickly corroded into a small pit.

Seeing that the venom could not get close to Xu Yuntian, Buchuan Changku guessed that Xu Yuntian must have some defensive ability. He roared and slashed his sickle-like arm towards Xu Yuntian.

Xu Yuntian roared: "Broken Void Fist!"

He raised his fist to meet him, and with a loud bang, Buchuan Changku's sickle-like arm was shattered.

Seeing that the situation was not good, Buchuan Changku turned around and wanted to escape. Xu Yuntian arrived at Buchuan Changku like a flash.

A sword appeared in his hand. As the sword swung, a cold light flashed. Buchuan Changku screamed, and his limbs and feet were cut off.

Buchuan Changku, who had only half of his feet, couldn't crawl at all. He screamed wildly: "I'll fight with you!"

Buchuan Changku opened his mouth and bit Xu Yuntian's head, and he wanted to bite Xu Yuntian to death.

Xu Yuntian sneered at the corner of his mouth, and the sword in his hand waved, and a cold light flashed. With a click, Buchuan Changku's head was cut off.

Buchuan Changku screamed, twitched on the ground, and then turned into an ineffective body. On the ground, there were headless corpses.

The few people who followed Buchuan Changku were frightened and turned around and wanted to escape. Yan Xiaoyu's eyes released blue light, and they were all immobilized.

Immediately afterwards, Yan Xiaoyu turned into several phantoms, and then there were a series of bangs. The people were hit by Yan Xiaoyu's palm, and their heads were all sunken and they fell to the ground one by one.

Xu Yuntian looked at the three men detained in the laboratory. They were dead, and then said to Yan Xiaoyu: "Let's go to the second floor!"
