On the way, Cheng Xiao suddenly thought that Li Shuaixi had no reason to risk his life to kill an eighth-level corpse brother.

"Why do you keep wanting to kill that rank 8 corpse brother?"

Li Shuaixi glanced at Cheng Xiao lightly.

"Research. This was my original purpose, but when I knew that you were from another world, I understood that you must have come to this world for a purpose, maybe the eighth-level corpse brother can surprise you. ”

"Why don't you ask me?"

Cheng Xiao asked.

"Whether it's or not, this eighth-level corpse brother has to die. I need it to look into. ”

"What are you studying?"

"The wisdom of mortals, you don't understand it."

"How I don't understand! You say, I don't understand that I eat live. What the hell! I still don't understand? ”

Li Shuaixi seemed to smile.

“…… One thousand words are omitted below. ”

"......" Cheng Xiao helplessly listened to what Li Shuaixi said that he didn't understand at all.

What genes, what mutations, a single word can be understood, but when it is fused together, Cheng Xiao is dizzy when he hears it.

"I know that!" Unexpectedly, Duan Mu's eyes lit up, and he actually communicated with Li Shuaixi without any obstacles.

"Aren't you a chemistry teacher?"

Cheng Xiao asked in surprise.

"These ...... It's a chemistry problem, or a chemistry-related problem. ”

Duan Mu looked at Cheng Xiao with strange eyes.

“…… MMP。 Cheng Xiao was speechless.

At this time, there are still ten minutes before Cheng Xiao's return.

The three of them were standing at the door of the supermarket, looking at the corpse brother in front of them who was like a hill and howling loudly.

"Whoa, whoa, whoa." As if sensing that the three people in front of him were not ordinary, the eighth-level corpse brother screamed even more violently.

"Do what you planned."

Li Shuaixi became unusually serious.

Immediately, the three of them scattered.

"How many causal points will this eighth-level corpse brother bring me! I'm going to kill him, kill him! ”

Cheng Xiao looked at the approaching eighth-level corpse brother in front of him, and shouted loudly in his heart.

Tread without a trace!

Seeing that the eighth-level corpse brother collided with him, Cheng Xiao stepped on the hellfire that came out of the soles of his feet and rushed into the sky, took out the Desert Eagle, and kept shooting towards the eighth-level corpse brother with the bullets of hellfire.

"Roar!" With a roar from the eighth-level corpse brother, a wave appeared beside it, and the bullets that Cheng Xiao shot past were all hit by the wave and fell to the ground.

As the wave ended, suddenly the sound of a sniper rifle came from the right.

With a bang, the sniper bullet that hit the eighth-level corpse brother exploded, but it only caused some damage to the skin on its surface.

Turning his head to lock on to Li Shuaixi, who was shooting at it, the eighth-level corpse brother actually stuck his hands on the ground, dug out a stone, and threw it at Li Shuaixi.

Fortunately, Li Shuaixi was agile and the stone was not hit.

The eighth-level corpse brother who had finished throwing the stone suddenly bent his legs, Cheng Xiao's face twisted, and he just wanted to escape, but was hit by a huge object.

It was the eighth-level corpse brother, he took advantage of his body, and he actually jumped into the sky in an instant, knocking Cheng Xiao into the air.

As a result of the collision, half of the body's functions were lost, and the skeletal muscles were also greatly damaged.

"System! Exchange for five Repair Potions. ”

[Successful exchange, spend 5 D-level causal points]

He drank the five bottles of blue potion that suddenly appeared in his hand, and then used the Flame Trampling Flame to rush towards the eighth-level corpse brother without a trace.

Constant firing, most of the bullets were ordinary bullets, and only a small part were bullets with Hellfire.

The eighth-level corpse brother was also alert, and seemed to know that the bullet with flames was the only thing that threatened him, so every time Cheng Xiao fired a bullet, the eighth-level corpse brother would send out that wave, and then isolate the bullet, constantly throwing stones at Cheng Xiao.

Sometimes huge stones, sometimes ten pieces in pieces.

There are still five minutes left before Cheng Xiao's return time.

At this moment, Cheng Xiao's left hand was gone, and after being hit by a stone the size of a football, he dragged and leaned on a layer of skin attached to his body, Cheng Xiao directly discarded that arm, and then continued to shoot at the eighth-level corpse brother with his right hand.

Cheng Xiao has been stepping in the sky for five minutes, and at this time, he has the acquired spirit stone in his mouth, constantly replenishing his energy so that he will not run out of energy.

But the energy of the acquired spirit stone is not endless!

There are still three minutes left before Cheng Xiao's return time.

The energy of the acquired spirit stone has been completely absorbed by Cheng Xiao.

After putting the acquired spirit stone into the storage space of the system, Cheng Xiao's energy could probably supply him with about two and a half minutes of stepping fire without a trace.

"Hurry up, Duan Mu!"

Cheng Xiao shouted anxiously.

At this time, Li Shuaixi was also a little powerless.

Barrett fired dozens of shots in a row, and in the face of the powerful speed of the eighth-level corpse brother, he had to concentrate and constantly change positions, and the burden on his body and mind was already obvious.

"It's up to you, Duan Mu." Li Shuaixi helped the frame of the mirror and fired another shot at the eighth-level corpse brother.
