Only treated his wife Cheng Fei's depression, Su Yuansheng felt that it was not enough, and Gu Cheng's injured head must be cured, so that his wife Cheng Fei would not secretly help Gu Cheng because of guilt or the like, and the relationship between him and her would no longer have discordant scenes because of Gu Cheng.

"You've thought it through. Meng Jian quickly guessed the significance of Su Yuansheng's second tube of medicine.

"In addition, I have put together a few things that you have asked me to prepare, and they will definitely meet your needs. Su Yuansheng took Meng Jian into a room inside, mysteriously opened a hidden safe in the wall, took out two metal balls the size of billiard balls and brought them to Meng Conversion.

"This is ......" Meng Jian looked at the two balls with some confusion.

"The culmination of my life's work, the nuclear power-driven mini-machine that has not yet been officially put into the market, is very functional, and covers all the functions required by your few things. Su Yuansheng said and threw the ball upward.

The ball did not land, but stretched out two extremely thin wings from both sides, hovering in the air like a hummingbird, revealing a small hole on it and shooting out a beam of blue light to scan and identify Meng Conversion's whole body, and under Su Yuansheng's operation, Meng Conversion's identity, voice and other information were confirmed.

"This wing is not a real wing, but a levitating force generated by directional magnetization of the surrounding air to sustain its flight...... The specific operation method is like this, I will show you all of them......" Su Yuansheng explained to Meng Jian in detail.

After learning how to control the operation of the ball, Meng Jian couldn't help but be pleasantly surprised. Having these two dome machines with him should be of great help to him in completing his rescue mission. It is true that as Su Yuansheng said, the function of this thing has covered all the content that he asked Su Yuansheng before. And it was far more than he had expected.

After all, it is now 2044, and in the era of quantum computers and nuclear batteries, mankind has completed another scientific and technological revolution.

"How long can it last if it's not charged?" Meng Jian confirmed with Su Yuansheng.

"The nuclear battery is now miniaturized, and it has three miniature nuclear batteries in it, enough to drive it to run non-stop for a whole hundred years without any problems. You can also put it to sleep when not in use, and set the time for it to be automatically woken up......" Su Yuansheng said proudly to Meng Conversion.

"That's good, huh. I've got you covered pretty much everything, and now there's one last thing. If only I could go back in time and see you when you were younger. How can I most effectively convince you that you don't think I'm ridiculous and willing to cooperate with what I'm doing?" Meng Yuan asked Su Yuansheng a crucial question.

"It's a lot of trouble to put it on someone's head, but for me, it's a very easy thing to do. I was meant to say that to you last time. But you were already gone when you thought of it......" Su Yuansheng said to Meng Conversion.

"Oh? ”

"That's right. Since I was a child, I have been very interested in the theories of the universe, time, and space, and I have always believed that people can travel through time and space, from the past to the future, and from the future back to the past, and I even naively set a password for this when I was nine years old......

"A code that only I know, I've been fantasizing that my future self might have found a way to travel back in time and help my past self, just like in the Terminator movie. But in order to confirm whether the person who came back from the future is really well-intentioned. Instead of maliciously trying to use me or kill me or anything like that, I've kept this password deep in my heart and never told anyone. Only the person who confirmed this password in front of me would believe that he really traveled back from the future to help me. ”

"I haven't been able to complete the theory of time travel until now, but I didn't expect to meet you who can travel through time and space. If you can go back in time with that password and find the me in the past who is still full of illusions about the future, you will definitely be able to convince me to carry out the one you want me to do according to your plan. Su Yuansheng explained to Meng Conversion.

"Then tell me the password. After Meng Jian heard this, he immediately told Su Yuansheng that he didn't want to be teleported back before he got the password.

"It's in the supercomputer I gave you, and you can see it on the desktop. It's a long combination of letters and numbers, and I can tell you again, but you can't remember it. Su Yuansheng and Meng Jian talked.

"Is this it?" Meng Jian turned on the crystal computer and asked Su Yuansheng.

"Well, that's it. Su Yuansheng nodded to Meng Conversion.

Although it was recorded in the crystal tablet computer, Meng Jian still tried to memorize the meaningless string of letters and numbers. Because he wasn't sure if it would have been lost in time travel, or erased by the system as an anachronistic item.

Fortunately, Meng Guan's memory has always been very good, and after memorizing it a few times and using associative memory, he quickly memorized this string of letters and numbers in his mind.

"There is also a letter here, and if you can take it back to the past, please give it to me personally, I can recognize my own handwriting, and if I want to change my tragic life, I don't think anyone can convince myself better than myself. Su Yuansheng took out a thick paper letter and solemnly handed it to Meng Conversion.

The past that Meng Jian traveled through is likely to be the kind of storage medium that does not have a USB flash drive, and paper letters will be more reliable. And this is a special paper made of high-tech that will not be lightly damaged.

In addition, the handwritten words are the best evidence to convince himself, Su Yuansheng has been planning these things for decades, and of course he will think about it more fully and comprehensively than Meng Conversion.

"It's a really good idea. Meng Jian put the letter away.

"The computer in your hand still has some theoretical and technological knowledge that I urgently needed at that time, only slightly ahead of that era, it is a treasure more precious than diamonds and gold, bring it to me at that time, I believe that not only me and my wife and daughter, but also Diqing Technology will be reborn. Su Yuansheng reminded Meng Jian again.

"I'll go to you. ”

"When are you leaving?" Su Yuansheng asked Meng Conversion.

"I'm not sure about that, maybe a few seconds later, maybe a few hours later, and there is no pattern for my time travel. Meng Jian shook his head.

"I wanted to ask you last time...... If you don't have anything else important to do at this time, why don't we talk about your time and space travel, maybe I can help you find some rules, and then find the technology you use to travel ......" Su Yuansheng asked Meng Jian expectantly.

"Do you know the upper realm, do you know the cracks in the realm, do you know the human realm and the ghost realm, do you know the fierce ghost clones bound by the system?" Meng Jian threw a lot of questions at Su Yuansheng.

Su Yuansheng's face was dazed......

"So, it doesn't make sense to talk to you about this, the world I'm experiencing and the world you're in probably not using the same rules. You can define a lot of things with the technology in your hands, but you can't define my life and what I've experienced. Meng Jian shook his head.

Just when Su Yuansheng wanted to open his mouth to ask Meng Jian something more, dizziness also came again at this time.

Darkness, silence.

……

1994.

In the private room on the second floor of a small restaurant in Huanghe City, the door is locked, and two men are sitting facing each other at the dining table.

"I'm from the future, and I know you've been fantasizing about space-time theory, and you're waiting for the future you, coming to you with that code that only you know. This is actually the real reason why I came to you. Meng Jian sat in front of Su Yuansheng and talked eloquently.

Su Yuansheng looked at Meng Jian blankly...... It was Meng Jian who said that he wanted to invest in him, so he met Meng Jian in the small private room of this coffee shop, but he really didn't expect that Meng Jian would actually say such a thing to him.

If you change to someone else, you will definitely think that the other side is a madman, just talking crazy, and when he grows up, Su Yuansheng has theoretically confirmed that time and space are impassable, so he doesn't believe what the other party says.

Until, when Meng Jian actually told him the password composed of letters and numbers, and then took out a crystal piece that was said to be powered by a miniature nuclear battery and powered by a quantum computer chip, he was irrepressibly excited.

The dreams of childhood and adolescence have become true!

Someone from the future has crossed over to him!

"Listen, I don't know how long I'll be here, I've been entrusted by you to change the tragic life of your wife and daughter dying and yourself in prison, so you have to listen carefully to what I'm going to say...... In addition, there is a letter from the future you to the present you. Meng Jian said and pushed a letter in front of Su Yuansheng.

After briefly skimming through the letter, Su Yuansheng swallowed a mouthful of saliva, his expression became even more excited, and even his hands trembled.

"The content of the last few pages of the letter is what I wrote to you, some of the things you have to do for me, without me from the future, there will be no future you, without the future you, you will still only be a tragedy now, this cause and effect cannot be destroyed, do you understand?" Meng Jian confirmed to Su Yuansheng very strictly.

"I understand. Su Yuansheng also nodded solemnly, at this time he was already convinced of what Meng Wei said. (To be continued......)
