After entering Experimental Area No. 2, Helen took a few breaths and then began to urge Gu Fan to quickly develop the blue potion.

"Blue potion, right? You can get as much as you want, but before that, I want to tell you a secret." The corners of Gu Fan's mouth raised, revealing a deep meaning, and his eyes shifted from one vampire to another.

One of the vampires felt uncomfortable and asked: "What do you think we are doing?"

Gu Fan's face was solemn: "I believe you are carrying a small surveillance device. Hand it over and let me destroy it, because what I am going to say next cannot be heard by Organization X."

The vampire pretended not to know: "What surveillance equipment are you talking about? I don't know what you mean."

"Okay, pretending to be confused, right? If you please, I won't start work and wait until the Dark Tower is finally captured." Gu Fan looked nonchalant, as if I was not in a hurry about this matter.

Helen frowned and waved her hand: "Tear down all the monitoring equipment you brought. If anything happens, I will be responsible."

"This..." Several vampires showed troubled expressions. They were ordered to monitor Gu Fan's every move.

Gu Fan said again: "If you don't cooperate, I will let the door open now. Anyway, I am not afraid of any mutated vampires. As for you, just ask for your own blessings."

"You're cruel!" In the end, the vampire gave in, took out all the surveillance equipment, and trampled them all to pieces in front of Gu Fan.

Gu Fan pretended to be trusting, and then continued walking forward, and couldn't help but speed up the pace. He was really worried about the safety of Li Shi and Ouyang Jin, so he had to go faster.

Gu Fan randomly found a room, and then said that there was a secret inside, and he could only let Helen and Xuelang accompany him.

The other vampires felt that they had been excluded, and immediately became anxious and wanted to follow him no matter what.

Gu Fan snorted coldly and punched the vampire away. The force was so powerful that the vampire instantly understood that they had no room to bargain with Gu Fan.

"I'll say it one last time, if you want to make blue potion quickly, you have to listen to me." After saying that, Gu Fan turned around and entered the room.

Helen and Xue Lang also followed in, which made Helen confused. It was reasonable for Gu Fan to trust her, but why did Xue Lang trust her so much?

This room is furnished with some bottles, cans, instruments and other equipment. It seems to be a place for experiments, but the problem is that this room feels abandoned for a long time.

"I hope you can keep the next thing a secret for me." Gu Fan said as he opened the wound with a dagger and let the blood drip into a bottle.

Helen couldn't understand: "Gu Fan, what are you doing..."

Xue Lang also wanted to say it, but the next scene shocked him. He saw the blood dripping in the bottle gradually turning from red to blue.

Helen and Xuelang instantly understood that this so-called blue potion was not made by Gu Fan. Gu Fan's blood itself was the blue potion.

"What on earth is going on?" Helen felt that things were getting more and more complicated.

Gu Fan said: "I got a blue potion from the forbidden area that can restrain vampires. After I drank it, my blood had the ability to restrain vampires."

"What? Gu Fan, you?" Helen and Xue Lang were horrified. If the organization knew about this, then after solving the mutant vampire, they would definitely try their best to kill Gu Fan at all costs.

Gu Fan behaved very calmly. Now that he has arrived at the No. 2 experimental area, he has entered a safe area.

"Wait a minute, Gu Fan, tell me, I can understand, after all, you trust me, but why did you tell Xue Lang." Helen was confused and began to have doubts about the relationship between Xue Lang and Gu Fan.

Xue Lang felt guilty and avoided Helen's eyes, which made Helen even more sure that there was something wrong with these two people.

At this moment, another door opened, and heavy footsteps came in the darkness, followed by the tall silhouette of a man.

"Is there anyone else here?" Helen and Xue Lang were very nervous.

Gu Fan acted very calmly and said: "I'm sorry, I really can't think of what to do, so I have to borrow your precious land."

Ao Sai appeared in front of the three people, and he said expressionlessly: "I already know the situation outside, and your blood is simply not enough."

"Do your best, unless you, Brother Aosai, have any good ideas." Gu Fan looked like he was in need of help, his eyes full of expectation.

"I'm sorry, all I can help you is to speed up your blood production and ensure you have an adequate blood supply." Aosai's words also made Gu Fan feel at ease.

Soon Gu Fan made a second bottle of blue potion. At the same time, he also ate the special food sent by Aosai and felt that his whole body was full of energy.

In the end, Gu Fan produced five bottles of blue potion in one breath, and then sent them to the hands of the vampires outside. He asked them to deliver these five bottles of blue potion to Organization X. Can they get it back from the mutated vampires?

The Dark City is all up to them.

The responsibility is heavy, and the vampires are a little scared. There are many mutant vampires blocking the gate? How can they kill them?

Gu Fan said for sure: "Don't worry, I'm responsible for attracting the attention of the mutated vampires. You guys run away quickly."

Someone immediately suspected that Gu Fan's motive was to get rid of surveillance.

Gu Fan disagreed with this. If he didn't go, someone else would have to go. The question was who had the courage.

Everyone looked at me and I looked at you, they all said that if they didn’t have the courage, they could only be Gu Fan.

"Okay, since everyone has no objections, let's execute it." After Gu Fan said this, he opened the door of Laboratory No. 2, rushed out alone, and started fighting with the mutated vampire.

Everyone couldn't help but admire Gu Fan when they saw how fierce he was.

Helen urged others to pass quickly, go to the elevator, and deliver the potion to Organization X. As for her own intention to stay, her mission was to keep an eye on Gu Fan.

Under the leadership of Xue Lang, several people rushed to the elevator as fast as possible, with a thousand blessings and ten thousand blessings in their hearts, never letting themselves encounter mutant vampires.

Helen stayed in Experimental Area No. 2. She listened to the roar outside and was very worried about Gu Fan's safety. She didn't know if Gu Fan could handle it and wondered if she should help.

Half an hour later, Gu Fan dragged his tired body back to Experimental Area No. 2. Although he was intact, his clothes were torn, which made him feel quite pitiful.
