"At that time, I finally decided to hide this technology for the time being because of these problems, and waited for the human moral level to develop enough to control this technology before releasing it, but I knew that I would not be able to do it in my lifetime, and finally I thought of this method to leave this technology to you, let you make decisions, and I believe you will do it well." Speaking of this, Professor Ma couldn't help but sigh lightly.

"Okay, that's all the questions I'm worried about, these problems will still appear in the future life research, with the rapid development of science and technology, once the moral level of human beings cannot keep up with the development of technology, then human beings may become a cosmic disaster."

"This video will be automatically destroyed after you watch it, I'm already a dead person, there is no need to leave you with any more sadness. This is the end of our bond, and it's a pleasure to meet you. In the end, even Professor Ma, who had always seemed very calm, shed tears, and in his time, it seemed that he saw Liu Xuan and Liu Xuan hugging and crying in front of the image through the camera.

"You must remember that you must stand upright, this is the last gift from a scientific researcher to mankind, goodbye." The video came to an abrupt end here, and then the computer screen went black.

When Liu Xuan restarted the computer again and opened the memory card, there was only a text document left in it, and the video just now had been completely destroyed. As Professor Ma said, since he is already a dead man, there is no need to leave Liu Xuan and Li Ping with a place of sadness.

Liu Xuan took the lead in calming his emotions, first opened the text and glanced at the formula, this is indeed the last formula he lacks, and then quickly withdrew the memory card safely, took it from the computer, and silently walked to the safe in his room, and stored the memory card inside.

Now is not the time.

This is what Liu Xuan is thinking in his heart now. According to Professor Ma and Liu Xuan's knowledge, now is not the best time, since the nuclear fusion engine, human beings have been bringing something from outer space, or precious metals, or useful stones, and the mass of the earth is increasing day by day.

The most important thing is that Liu Xuan has heard that because the wear and tear of the atmosphere will greatly deplete the valuable asteroid blocks brought back from outer space, some institutions and companies are building a protective shield in an attempt to make the atmosphere wear out the protective shield and not affect the valuable asteroid blocks. If you do this, the anti-virus effect of the atmosphere will be completely lost.

After careful consideration, he knew that human beings needed this technology now, and in order to make them qualified to master this technology, Liu Xuan decided to write a new theory by himself, or to develop the old theory.

Standing on the shoulders of giants will see farther.

Without further ado, after explaining to Li Ping, Liu Xuan was ready to return to the research room to write his own theory, that is, the theory of planetary mass constancy, referred to as mass constancy. Liu Xuan hopes that through this theory, people will understand the dangers of bringing back those high-quality objects from outer space.

When he returned to the research room, Liu Xuan found that things were not quite right, according to the original time, the current researchers should be working hard to study the aspect they are responsible for, but now? It was as if someone was waiting, and all the researchers, including Mu Guang, were either standing or sitting at the door.

Seeing Liu Xuan come in, Mu Guang first walked over and warmly shook hands with Liu Xuan, that look, as respectful as he wanted, which made Liu Xuan a little confused.

Then almost all the researchers gathered around, looking at Liu Xuan anxiously. Liu Xuan's heart was a little hairy when they looked at him, he didn't know how the researcher who was so cold to him could become like this.

"Liu Xuan, don't hide it, you should already know the final formula." Mu Guang next to him took the lead in smiling and said to Liu Xuan, this appearance made Liu Xuan feel disgusting.

Liu Xuan chuckled in his heart, and instantly knew what had happened. This Mu Guang usually looks smiling and plain, but how can this kind of person sit firmly in the highest position in a research laboratory? I'm afraid no one will believe him if he's not smart. It seems that this Mu Guang has seen something from Liu Xuan's face and actions in the morning, and told his researchers that this will happen just now.

"Professor Mu, what are you talking about? I don't understand. "Liu Xuan can only pretend to be crazy and stupid now.

"You kid, don't hide it from us people, you can guess by looking at your expression in the morning, you have got the last and most critical formula, we know that you have the most credit, so we have no opinion on writing your name at the front of the research paper, and you can follow the name of our research laboratory, but now you should at least show us the formula, and we will help you verify whether it is right or not." Mu Guang was still smiling.

"Yes, Professor Liu, we are all researchers, let's just take a look at the experiment."

"Professor Liu, don't be humble anymore."

“……”

As soon as Mu Guang spoke, the researchers who had already gathered around him also hurriedly spoke in response.

A look of struggle flashed on Liu Xuan's face, and he didn't speak.

But Mu Guang is an old fox after all, seeing the look on Liu Xuan's face is certain, Liu Xuan already knows the final formula, he just doesn't want to share it with everyone, he wants to swallow it alone. This is also what the researchers in the laboratory are worried about. They have worked hard for several years, and if only one person is allowed to get this glory, they will not be reconciled.

"Liu Xuan, you said that our laboratory treats you well, all the dirty work and dangerous research are all done by us, as long as you have an idea, we are all completing it for you. It's not an exaggeration for us to sign our names on it. Mu Guang was kind and angry, and used his usual research to persuade Liu Xuan.

Originally, Liu Xuan was still struggling in his heart whether to explain or not, but when he heard Mu Guang still have the face to say these words, he couldn't help sneering in his heart, originally he thought that Mu Guang was a person who really contributed to the cause of scientific research like Professor Ma, but he didn't expect it to be such a person, and it was really unpredictable.

Liu Xuan couldn't help but think of his own research again, it was normal at the beginning, his research was good, the progress was very smooth, and all the researchers were cooperating with his work. But later, when there was a little achievement in research, the researcher gradually isolated Liu Xuan as if they had discussed it.

Originally, Liu Xuan didn't pay attention to the universe, he thought that it might be his own lack of ability, and they didn't want to help anymore, after all, this is human nature, and they will choose a good leader by themselves. But then they came around to help him again, so back and forth, so that Liu Xuan couldn't figure it out, Liu Xuan kept choosing to trust them, and told them his new discoveries again and again. Now Liu Xuan suddenly understood that these people had actually been stealing his research results.

I left Liu Xuan because I thought I could do it, and I came back because after research, I found that without Liu Xuan, my progress would be slowed down, so it caused this repeated appearance.
