Lan Ya came to the underground testing area, saw Guo Yufei standing there with a confused face, and called softly, "Xiaofei, don't think about it first, I'll check it for you first."

Guo Yufei sorted out his mind, and couldn't help but shake his head and smile bitterly, he had nothing to worry about, he hadn't proved what this thing was, and he was worried here.

After blood sampling and testing, Guo Yufei waited for a long time, and then saw Lan Ya, who was wearing a chemical protective suit, walking out of the laboratory and handing him a report in his hand.

Guo Yufei hurriedly opened it to take a look, and after detecting nuclear fusion in his body, the DNA picture showed that the double helix structure had become half red and half yellow.

"I can only say congratulations, you have evolved again, your body has absorbed the energy of the nuclear explosion, and the energy of the nuclear explosion has been absorbed by the cells because of your later stimulation madness, because the nuclear energy is too large, so it cannot be completely absorbed, and the general metabolism cannot replace him, so I have to congratulate, you have become a mobile nuclear power plant." Lan Ya said enviously.

"What's the harm in that?"

Lan Ya thought for a while and said, "The disadvantage is that if you can't control it well and let it really become a part of your body, then it is very likely that if you are not careful, you will explode with a bang."

Guo Yufei couldn't help but shudder, he had become a nuclear bomb, or a nuclear bomb that could explode at any time.

Looking at Guo Yufei with such an appearance, Lan Ya couldn't help but cover her mouth and laugh: "Haha...... Tease you, don't worry, it's not that easy to fry, but I suggest you work out a little more so that your body can absorb this energy, and then you will become stronger. Remember, there will be blessings after not dying in great calamities, after all, not everyone can be baptized by a nuclear bomb and not die."

"I was just lucky, I was still about 2,000 meters away from the source of the explosion, so I was lucky to survive." Guo Yufei said with a happy face.

Lan Ya pursed her lips and smiled, and took Guo Yufei out of the underground testing area, on the way Guo Yufei asked some specific information about this mission, Lan Ya said that these questions can be asked to the ghost, it was the ghost who brought a few people back.

Saying goodbye to Lan Ya, Guo Yufei left the biological area and walked towards the living area, on the way he was thinking about how to greet the ghost, after all, this person himself had not been in contact with before, and he didn't know what his temper was, in short, he listened to his voice before he fell unconscious, which was a little gloomy.

Before coming to the ghost room, Guo Yufei took a deep breath and knocked on the door gently.

"Enter." A cold voice rang out from inside the door.

Guo Yufei shuddered involuntarily, this voice was several times colder than Mo Yuanlai.

Gently pushing open the door, Guo Yufei was stunned, he had thought about many possibilities of what the ghosts were doing on the way. For example, the ghost is exercising, eating raw meat, sleeping and even playing games, but he never expected that the ghost would actually sit at the table drinking coffee and reading magazines, and he was stunned for a moment, how could such an indifferent person behave so down-to-earth like a neighbor's uncle.

At this time, the ghost had already taken off the mask, and it was an angular and handsome face, at least it looked no more than thirty years old, and its dark eyes were very deep.

"That's... I don't know what to call you?" Guo Yufei scratched his head and said.

"I don't have a name, you can just call me a ghost, if you feel awkward, it's like shouting King Kong, just call uncle." The ghost put down his coffee, put the magazine aside and stood up.

Guo Yufei nodded, thanked him again, and asked about what happened that night.

The ghost pinched his eyebrows, I don't know if it was because his eyes were uncomfortable after reading the magazine for a long time, or because the question asked by Guo Yufei gave him a headache, and after a while, he spoke, and Guo Yufei was stunned by one sentence.

"That night, I was actually nearby, and I brought in that A-class demon."

"Why?" Guo Yufei asked puzzled, but he was a little unhappy in his heart.

"Because the owner of this demon may be the murderer of your father." The ghost was not angry because of Guo Yufei's tone, but continued to speak.

"Two years ago, your father had an accident, so I left the team to go out to find clues, and the process was long and painful, because it was different

I haven't seen a capable person before, and it seems to have come out of nowhere."

"I've traveled all over the world in the past two years, and I finally found the trace of that man not long ago."

Guo Yufei gradually calmed down and listened to the ghost continue to tell.

"That person is very strong, it should be an S-level powerhouse, I fought with him, it's a pity that I'm not his opponent, because of my ability, I can't stay if I want to go."

"On the way back, I heard that you carried out the first mission, so I went to the mission point in advance to wait for you, I never thought that the A-class demon raised by the man has been following me, and I fought with it at the mission point, resulting in casualties among ordinary soldiers, and the mission target was also killed, and when you arrived, it was the truce between me and him, and I was injured with it, and I didn't help because I couldn't interrupt my stealth breathing, but fortunately, you killed it."

"However, don't think you're strong enough just because you killed this A-class demon, it was already fighting with me until it was seriously injured before you came, otherwise you think you can destroy the A-class demon with your madness alone!"

With the ghost's narration, Guo Yufei no longer complained that the ghost had attracted the A-class demon, but knew from the story told by the ghost that this person had been looking for his father's killer for himself.

"Uncle Ghost, thank you, I don't know how to describe it, in short, thank you for your hard work in the past two years." Guo Yufei bowed deeply to the ghost.

The ghost hurriedly dodged to the side, and his tone softened: "You don't have to thank me, if it wasn't for your father, we would all be dead, and we owe your father his life."

Guo Yufei didn't know what his father meant in this squad, but he could see respect in the eyes of these people, including Bai Lao.

"Uncle Ghost, didn't you say that all demons are monsters without thinking logic? Why can that man be raised?" Guo Yufei asked puzzled.

The ghost's eyes were a little flustered, as if he was thinking about something terrifying.

"It's true that the alien demon has no thinking logic, but that person is an S-class dual ability powerhouse, and controlling creatures should be one of his abilities, I have seen five different A-class aliens around him, and there are no other unknowns, in short, he is very strong, and he can destroy the existence of the entire purification team with the power of one person."

Guo Yufei's mouth grew in surprise, five A-level demons, plus he should be an S-level powerhouse, this kind of equipment even the purification team including Bai Lao has to be avoided, when will his father's murder revenge be avenged, is that kind of S-level powerhouse invincible?

An invisible pressure made Guo Yufei a little breathless, and he suddenly felt how ridiculous it was for him to be complacent because he had killed an A-class demon.

"Uncle Ghost, take the liberty of asking, what kind of mission did you carry out back then, and why did you provoke such a strong person?" Guo Yufei tried to calm down and asked in a low voice.

The ghost fell into deep thought, and did not speak for a long, long time, but walked over to the table, picked up the cup of coffee, and drank it all.
