Shirley hesitated for a moment and finally said, "Okay, don't forget to give me back." After that, Shirley took off the necklace and handed it to Duan Xuan.

Just the moment Duan Xuan was holding it in his hand, "Didi!" The annoying system prompted the sound.

"Tip: You have used improper means to obtain G virus samples. Please return them to Shirley Birkin as soon as possible, repeat! Please return them to Shirley Birkin immediately! Otherwise, you will be hostile to all the protagonists when you enter the biochemical scene next time!"

“Tip: Repeat again…”

Duan Xuan was slightly stunned, quite surprised that the system even had to interfere with this!

"If you are hostile, just be hostile! I don't know the next time I come to the biochemical series, I will be in the Year of the Monkey and Horse Month. I must become stronger now! Even if I use any method!"

Duan Xuan gritted his teeth and took Shirley's necklace.

"Warning: Because I used improper means to deceive Shirley Birkin's G virus sample, I chose to let go of William Birkin's option task and automatically cancel it! When I encounter William, the other party will launch endless attacks on you!"

Duan Xuan was helpless.

"I knew the system could not allow me to obtain the G virus so simply!!"

Are you enemies with William who was injected with G virus?

Duan Xuan really wanted to shout to the god: "I can't do it."

But for Shirley's virus sample, to enter the "Kork" University, to become stronger! Be stronger, and become stronger! He had to bite the bullet.

After a while, he smiled and said to Shirley, "I will give it back to you when the matter is over."

"Brother, are we going to continue walking deep into the basement?" Shen Xuan asked. Now, Duan Xuan is undoubtedly their backbone.

Duan Xuan thought for a while, according to the game plot, William Berkin and the police chief were there, how could he complete the task if he didn't go!

Even if he can't beat William, he wants to try it!

"That Shirley..." Shen Xuan was afraid that Shirley would not accept it when she saw her father turn into a monster.

"Don't worry." Duan Xuan saw through what she was thinking, so he explained: "At this time...well, he should have evolved into the second form of the G virus, and he can't tell from his appearance."

"What are you talking about?" Shirley tilted her neck, looking curious.

"The child can't understand." At the end, Duan Xuan said to Shen Xuan again: "You and Shirley are behind me, be careful along the way."

As for the battle outside, Duan Xuan was too lazy to think about it. Anyway, Claire would not die easily, he was the protagonist! On the other hand, Song Yunfei and others... die if they die, and they have nothing to do with him.

The three of them turned left and right in the basement, and moved forward in the dark. Fortunately, there was no fork in the road, otherwise he, a fool, would have to be lost.

Soon, Duan Xuan and the other two came to an end.

What caught my eye was an empty room. The feeling inside the room was very depressing, making people feel a little breathless. Strangely, the surrounding walls were not made of cement, but were all made of glass. Looking out of the glass from the room, it was pitch black.

Duan Xuan didn’t understand why glass was installed in the basement? Where did it lead to besides glass?

But now he had no intention of thinking about this, because, in the center of the room, there was a person lying on the ground motionlessly, not knowing whether it was death or life. If he guessed correctly, he should be the director of this police station!

Duan Xuan and the other two hurried over to check the director's situation and found that they were still breathing a sigh of relief.

The director slowly opened his eyes and saw Duan Xuan and others. His face turned extremely ugly. He said with difficulty: "Let's go, go quickly, otherwise it will be too late!"

The three of them were confused and confused. Duan Xuan was about to ask him something, but it was too late!

I heard a sudden "Clang!" sound, which shocked several people and looked up!

I found a person rushing in from outside the glass... No! It looks more like a human-shaped monster!

The director's face was ashamed, and the three of them were also shocked.

"roar!"

The humanoid monsters did not attack them, but just stood there and howled in pain. At the same time, something strange happened!

The monster's body is constantly changing, sometimes expanding outward and sometimes contracting inward. At the beginning, there are only two small bulges on the back, which gradually grow and grow as time goes by.

William Berkin?

Duan Xuan can guarantee that the human-shaped monster in front of him must be William Berkin!

"What is this?" Chen Xuan and Shirley were shocked and their bodies couldn't help but retreat.

Duan Xuan was also extremely frightened. "He is actually going to evolve! Evolve from the second stage to the third stage! That is to say..."

Duan Xuan swallowed and spitted, but couldn't continue.

Chen Xuan continued, "In other words, we can't beat him?"

Although Duan Xuan didn't want to admit it, he still nodded.

"Then we."

Suddenly! Duan Xuan woke up in shock and said firmly: "Retreat! Retreat quickly!"

"Hahaha, it turns out that they are all hiding here!"

At this time!

No one expected it!

A few more people came in from outside the door and looked closely! It was Song Yunfei and Qiao Weiwei, and three other people they didn't know.

Song Yunfei showed a hint of sinisterness and said, "No one of you is allowed to leave!"

The next second, the group of them became even more excited when they saw William who was in the mutation.

"William is here, Duan Xuan is here, and the G virus is also..." As he said that, Song Yunfei glanced at Chen Xuan, and his lustfulness was even stronger: "Also, the beauty is here too. Haha, you are all mine today!"

"Duan Xuan, what should I do?" Chen Xuan felt a little crisis. There was a tiger in front and a hungry wolf in the back.

And this wolf is still a pervert!

"Let's wait and see." Duan Xuan was too lazy to talk nonsense to Song Yunfei and others. The other party definitely couldn't let them go. "Wait for the opportunity, we will run away!"

As he said that, he led Chen Xuan and Shirley to retreat as much as possible and stay away from William Berkin. "If we are enemies with them now, we will only suffer both losses and will eventually die at the hands of the monster."

Song Yunfei certainly understood the same principle, which was also the reason why he had never attacked Duan Xuan.

"Duan Xuan, wait for me! I will ask you to repay that slap sooner or later!" Song Yunfei roared: "Wait until I complete the task first, and then I will deal with you!"

"shot!"

Song Yunfei shouted loudly and immediately shot William with three other subordinates!

When each bullet hit the monster, it sprayed out a red and yellow viscous liquid, like blood, but without the smell of blood. In contrast, it was a strong odor. It was indescribable, but it was disgusting.

On the other hand, William Berkin not only did not get knocked down by random guns, but evolved faster! His whole body was blood red, huge eyeballs emerged from all over his body, and he kept turning. The small bag bulging behind it now turned into two thick and long claws, plus his original arms.

It actually has four arms?

William is no longer like a human! He has become a monster completely!

As the body stops changing, the third form evolves!

"roar!"

William Berkin roared at Song Yunfei and others, and then he kicked his legs and came to the front. The speed was so fast that it was astonishing!

In the blink of an eye, the minions brought by Song Yunfei were torn to pieces by the angry William Berkin before they even screamed.

Broken arms, broken legs, blood is everywhere! It is like a picture of hell.

Now, Song Yunfei did not look so energetic just now. He and Qiao Weiwei were extremely scared and their bodies retreated frequently.

This is too fucking strong too!!

He could not have imagined that William Berkin would be so strong! Otherwise, he would not have been so stupid that he would have dared to fight hard with so many people.

"You, don't come here!" Song Yunfei said tremblingly as he looked at the monster approaching him step by step.
Chapter completed!
