While Wei Fan kept killing zombies, Dr. Chen had already brought Mo Xuan to the underground research institute.

"Mo Xuan, do you know what you are doing? If this method falls into the hands of zombies, it will be an extremely huge disaster for humans." Dr. Chen said.

"An Ran, you forgot again. I am a zombie now, and I am the king among zombies. Of course, I have to think about my people." Mo Xuan said with a faint smile.

"You are hopeless!" Dr. Chen shouted angrily.

Mo Xuan spread his hands and continued to follow Dr. Chen inside.

After walking to the door of the institute, Dr. Chen suddenly stopped and said, "Just wait here, I'll get it for you."

As he said that, Dr. Chen took it first and walked in.

But Mo Xuan ignored Dr. Chen's words and followed him in.

"Didn't you say you won't come in? Do you understand?" Dr. Chen said angrily.

"It doesn't matter if I can't understand it, just be fine if you can understand it." Mo Xuan said.

"Hmph!" Dr. Chen snorted coldly.

"The information on that laboratory bench is what you want." Dr. Chen pointed to a laboratory bench and said to Mo Xuan.

Mo Xuan walked over, picked up the stack of information, and took a look at it, "That's all?" Mo Xuan asked.

"Of course not, there are those over there." Dr. Chen pointed to another laboratory bench and said.

Mo Xuan walked over again and picked up the information on the laboratory bench.

In this way, wherever Dr. Chen pointed, Mo Xuan would go to somewhere to pick up the information. In a short while, there was already a thick stack in Mo Xuan's arms.

"Are you playing tricks on me?" Mo Xuan also reacted at this time and said in a cold voice.

"Yes, I'm just playing tricks on you. You won't naively think I'll really give you the information." Dr. Chen looked directly at Mo Xuan and said.

"Aren't you afraid that I will kill him?" Mo Xuan sucked Wang Jianguo over, grabbed him in his hand and asked in a cold voice.

"What is this sacrifice compared to the life and death of the entire human race?!" Dr. Chen said excitedly.

"Hahaha, I deserve to be Chen Anran I know. She has always been so stubborn." Mo Xuan suddenly laughed and threw Wang Jianguo on the ground and said.

"But I don't need any information. It's enough to have you." As he said that, Mo Xuan grabbed Dr. Chen and walked out.

"Let me go!" Dr. Chen kept struggling, but his strength was a bit insignificant than Mo Xuan.

At this time, Wei Fan outside was still killing, but he had never escalated.

Wei Fan suddenly became anxious. If he didn't upgrade, he still didn't have the ability to fight against Mo Xuan.

There was no way, Wei Fan had to continue killing.

After a long and uninterrupted killing, Wei Fan was also very expensive. Wei Fan already felt his arms tremble.

However, Wei Fan did not dare to stop and rest. Only by constantly squeezing himself can he break through the limit.

After killing another wave of zombies, Wei Fan felt that he had reached his limit, but the upgrade prompt sound did not sound for a long time.

At this time, Wei Fan's experience value was almost full. I believe that he could upgrade by killing a wave of zombies.

But Wei Fan had no chance anymore, because in Wei Fan's sight, Mo Xuan pulled Dr. Chen and was walking out of the school.

"Oh, it's amazing. I've killed so many of my subordinates, but I guess you're no longer able to do it now. I'm afraid you won't even have the strength to kill chickens." After Mo Xuan came out, he swept around first, then looked at Wei Fan and sneered.

Wei Fan ignored him, closed his eyes and began to adjust his breathing.

"Take it slow, but my goal has been achieved, so I won't play with you anymore. I'll let my subordinates play with you." Mo Xuan said to himself.

"Mo Xuan, you don't give your credit!" Dr. Chen looked at Mo Xuan fiercely and shouted loudly.

"Haha, don't you think it's too ridiculous to talk about credit with a zombie?" Mo Xuan said with a smile.

Then Mo Xuan pulled Dr. Chen and continued walking forward.

"I haven't lost yet. It's not appropriate to leave like this." Wei Fan stood up from the ground with great difficulty and said.

"Oh? Do you think you are my opponent?" Mo Xuan said calmly.

"How can you know if you don't try it?" Wei Fan showed off a defensive look.

"Then I will fulfill you." As he said that, Mo Xuan waved his hand and shot an energy ball and hit Wei Fan.

This inconspicuous energy ball, but it carries a huge power. As soon as it comes into contact, it smashes Wei Fan and throws it out.

When the person was in the air, Wei Fan spurted out a mouthful of blood. Then Wei Fan landed directly in the group of corpses and killed several zombies.

But perhaps because of Mo Xuan's control, the zombies did not take the opportunity to attack Wei Fan.

Seeing Wei Fan's appearance, Mo Xuan shook his head and continued to walk forward.

"Don't leave, the matter is not over yet." At this time, Wei Fan stood up again tremblingly and said with difficulty.

This time Mo Xuan was directly this time. Seeing Wei Fan stand up, he didn't say anything, and directly smashed an energy ball over.

Wei Fan was knocked away again without any surprise. With the same posture and the same result, Wei Fan smashed into the corpse group again and killed several zombies at the same time.

However, Violation soon stood up again. In this way, Wei Fan was beaten, then stood up, knocked down, and stood up again, and repeated more than ten times.

At this time, Wei Fan's body was already in tatters and blood was everywhere.

After being knocked down again, Wei Fan suddenly burst into laughter.

Hearing Wei Fan's laughter, Mo Xuan frowned and stared at Wei Fan lying on the ground.

The reason why Wei Fan laughed was that just after he was knocked down again, he remembered the long-lost system prompt sound in his mind.

"Ding, congratulations to the host for its successful upgrade, and its current strength is level 6 king level."

Feeling the powerful force surging from his body instantly, Wei Fan was excited and laughed happily.

He turned over from the ground and stood up. Wei Fan looked at Mo Xuan in front of him and said, "I should be your opponent now."

Although he was asking, Wei Fan looked at Mo Xuan with a deep disdain in his eyes.

"You seem to have become stronger." Mo Xuan said.

"This is all thanks to you," Wei Fan said.

Indeed, if Mo Xuan hadn't defeated Wei Fan again and again, Wei Fan wouldn't have had the chance to upgrade.

Although those zombies were killed by Wei Fan, they are still considered Wei Fan's experience value.

Wei Fan's accumulation over the past dozen times finally made up enough experience in upgrading.

At this time, Wei Fan was full of confidence. When he looked at Mo Xuan, he was already a little eager to try.

"Although you have become stronger, you are still no match for me." Mo Xuan said confidently.

"Stop talking nonsense, I will know after I have beaten it, I see what I want!" Wei Fan roared, and then rushed towards Mo Xuan.
