When Du Fei chose to exchange abilities and items for people other than himself, he thought that one day he would discover the secret of the exchange system, but he never thought that it would be discovered by someone who had never met before.

However, Yan Dingtian didn't completely guess his secret, he guessed the special power of aliens, not the exchange system, and it was not something more specific.

"You don't have to be surprised, when you decide to use this special power, it is destined to be no secret, the more you pay attention, the more people will doubt, I don't know if I am the first to guess, it will definitely not be the last." Yan Dingtian regained his calm mood and said.

"How did you guess?" Du Fei wants to know where his biggest loophole is, although he has always had a lot of loopholes in his behavior, he is still curious.

"Because I have a very similar ability to you, to take on the physical form of something in my mind. However, after countless attempts, I couldn't get what I didn't understand. Yan Dingtian explained, and then gave an example, "For example, I want to get a space battleship, but I only get a model of a space battleship because I don't know anything about its internal structure. ”

"You mean that if you only need to know something, you can present that thing?" Du Fei asked, this ability is really similar to the exchange system.

"Yes, as long as I can find the same elements in the material world. For example, if I hold uranium-235, I can build a nuclear bomb in one second. Yan Dingtian replied.

"Heaven is really not thin on you." Du Fei sighed.

Yan Dingtian's source ability is only too against the sky, as long as he knows the principle, as long as he has the internal structure, he can make anything.

On the surface, it looks like a human body factory.

But in the hands of smart people, it will be an incomparably ungodly existence.

For example, many cutting-edge technologies are now only studied on drawings and computers, such as the mass-energy equation, which was just a theoretical equation from the beginning. If you want to make a physical object, you can't do it without decades. In Yan Dingtian's hands, as long as the drawings are designed, he can make the real thing.

"God really isn't thin on you."

"If it was before the end times, I would have thought it was ironic, but now it is. Having said all this, you haven't answered me yet, is your special ability because of aliens. Yan Dingtian replied.

"Didn't you already guess that?" Du Fei asked rhetorically.

"I hope to get a definite answer from you." Yan Dingtian said.

"I do have a special ability, similar to yours, maybe more advanced. But I don't know where this power comes from, but it's definitely not earth technology, that's all I can say. Du Fei didn't continue to hide his special abilities, but he didn't tell the whole truth, but it was more true to say so.

"I like your honesty, unlike a lot of other seemingly smart people who always want others to guess what they think, but they don't hide it well." Yan Dingtian said.

"What do you want to do now?"

"Do you mean to catch you and study it?"

"Don't you want to?" Du Fei asked rhetorically.

"I want to, I don't want to. Because there are also people who want to do research with me, and we are the same, and we both have enough resistance power. It forces us to stay strong, and once we lose the power to protect ourselves, our fate will fall into the hands of others. Yan Dingtian replied.

"So you still want to."

"Yes, so I hope you'll always be able to protect yourself until I can catch you." Yan Dingtian didn't hide his thoughts at all.

Hearing this, Du Fei was not worried that Yan Dingtian would reveal his secret. Because if this secret is leaked, it will only attract more people to arrest him, but it will not do him any good, and if he is obtained by Freemasonry or other forces, it will be harmful.

However, the existence of Yan Dingtian buried this secret for himself.

Because Yan Dingtian has the ability to create various things, it is very similar to the exchange system, and it is also proved from the side that the exchange system can be a source ability.

"Is there anything else you want to tell me?" Yan Dingtian asked calmly again.

"Why do you ask?"

"Because, I can sense that there are still many secrets in you." Yan Dingtian said.

"Aren't you smart? Can't guess for yourself? ”

"I don't like the term "smart", in fact, everyone's brain structure is the same, the difference is that I use my brain to think more things that others don't think." Yan Dingtian replied.

"Everyone has secrets, but I can't find a reason to tell you." Du Fei said.

"How about exchanging information?" Yan Dingtian proposed.

"Yes, but I don't have anything I need to know from you." Du Fei replied.

"Well, I'll ask me what I want to know first, and you don't have to answer me. I'll say something you might be interested in until you feel that what I'm saying is enough to exchange what I'd like to know, and then you can answer my question. Yan Dingtian said.

Du Fei didn't expect Yan Dingtian to be so happy, you must know that if he cheats, he won't answer even if he lives or dies, according to this agreement, he can't do anything about himself.

"You're not afraid that I'll play tricks, why don't you answer your questions?" Du Fei asked.

"I'm sure you're not that kind of person, and I'm sure we'll have a lot of opportunities to work together in the future." Yan Dingtian said, and began to ask, "I want to know the secrets of Pandora's creatures, I think you must know more than everyone else." ”

Du Fei bowed his head, indicating that there was indeed a secret about Pandora's creatures.

"Okay, I guess you'll care about Ji Tielan's affairs. Speaking of which, I want to explain first, I am my father's adopted child, Zhou Wenjun is my father's biological son, and Ji Tielan's matter is that the Ji family wants to calm the resentment caused by Zhou Wenjun. Yan Dingtian observed Du Fei's expression as he spoke, and after finding that he was not interested, he turned to say, "You seem to know all this, but the source energy weapon on Ji Tielan's body was made by me, I don't think you should know." ”

Du Fei really didn't know, Yan Dingtian could see it from Du Fei's expression, and then said: "This set of source energy weapons was given to Ji Tielan by me through Ji Gaorong, in order to give her the ability to leave the imperial capital. Because the matter about her has affected my normal work. ”

Du Fei was surprised again.

"There are also a lot of contradictions within the Zhou family, but these things are all stupid human games, and I don't want to get involved. I just wanted to work quietly, so I let Ji Tielan go, and the source energy weapon on her body didn't exert its full power, because it required Pandora Crystal as the energy core to activate all functions. Yan Dingtian said.

Yan Dingtian looked at Du Fei and saw that Du Fei was not very interested in this information, so he continued: "Regarding the crystallization ignition technology, I think the 51st Military Region has also begun to study it, and the estimated time for the finished product in the imperial capital is one year and six months in the end of the world, and I think the 51st Military Region will only be slower." ”

Du Fei was really a little interested this time, if Yan Dingtian didn't have any dry goods, he wouldn't mention the crystallization ignition technology.

Sure enough, Yan Dingtian continued: "I found that the explosion situation of the crystallization ignition is very similar to the Super Energy Wave Destruction Device in Area 11, so I have sent people to Area 11, but no one can come back, if you can go there, you should be able to gain something." ”

"It's not like a message, it's a request for help." Du Fei said.

District 11 is the division of the alliance of countries against the Japanese state, and now the news of District 11 is intermittent, and it is not far from complete destruction.

"That's true, you should be able to see that my own movement is not convenient, and my combat effectiveness is not outstanding, I think it should not be difficult for you to go back and forth to Lake Baikal in one day, and go to District 11." Yan Dingtian said.

"In this way, I can feel that you are different from those who fight for power, so I want to ask you a question, please answer me truthfully." Du Fei said solemnly.

"Just ask."

"What are you after?" Du Fei asked clearly.

This question is very important, because from the conversation, it can be felt that Yan Dingtian is a very special person, and he does not seem to have the inferior nature of ordinary human beings.

"Get rid of the aliens." Yan Dingtian replied.

"What about other than this? What is your ultimate pursuit in life? Du Fei asked.

"Nope."

"And what about before the end times? What do you want most. Du Fei asked again.

"Nope. It was only after the end of the world that I had a sense of existence. It's like doing a math problem, you can concentrate in the process of calculation, just want to get the answer, but when the result comes out, you lose your goal. Yan Dingtian replied.

Du Fei has basically determined that this Yan Dingtian is a pervert, at least his way of thinking is completely different from that of ordinary people.

"OK, why do you want to get rid of alien creatures?"

"I don't want to, but this is the last math problem my grandfather left me, and I have to find out the results." Yan Dingtian replied.

Perverts are terrible, but perverts usually don't deceive people, between believing and not believing, Du Fei chose to believe Yan Dingtian's words.

"Well, I believe what you say. I guess you're going to sacrifice anyone to get the answer to this math problem, and I'm no exception. Du Fei said tentatively.

"Yes, I can sacrifice anyone, including myself, to get answers." Yan Dingtian added.

"Have you ever thought that when you get the answer, you lose your purpose again, and life becomes boring again." Du Fei continued to test Yan Dingtian's way of thinking.

"That's after you get the answer, and you don't need to think about it in the process of calculation." Yan Dingtian replied.

"You're a pervert."

"Thank you."

"I like people who don't beat around the bush, I'll tell you everything I know about Pandora's creatures......" Du Fei said about Pandora's creatures coming from Kepler-22b, and about the wormholes made by high-dimensional dimensional insects, but omitted the matter of Protos Star Spirit.
