"I'm going, you can go to the ground to play by yourself, didn't you find a few girlfriends?" Liu Xuan said to Li Ping in the room.

"I'm going out, what about the kids?" Li Ping glanced at Liu Xuan and said. Then Lianbu walked in front of Liu Xuan, tidied up his clothes, and sent Liu Xuan out of the house.

Liu Xuan, who was walking on the streets of the dungeon, was full of emotions, and it had been five years since he woke up to participate in the research, and too much had changed in the past five years.

As the only close "centennial man", Liu Xuan and Li Ping got married two years ago, there is not much love, they are more like friends who rely on each other, they can't do without each other, and the wedding of the two did not make a big show, but submitted the marriage application to the higher department, and the two lived together after the approval of the higher department.

A year ago, Li Ping gave birth to a boy, in this high-tech era, their child is still the most ordinary life, Liu Xuan still remembers the first time he saw this boy, in the hospital, by Li Ping's side, it looked so small, but Liu Xuan knew that what was lying on the bed was all he had, and he needed to protect it with his life.

Now Li Ping has also given up her research work and is taking care of the children at home full-time, in her words, Liu Xuan is outside the home, and she is inside. They are the most ordinary family in this new era of earth.

Liu Xuan, who is so happy in life, is unsatisfactory in his work, although their whole team has been studying for five years, but this problem has not been solved, there are many researchers left, and many researchers have been added, five years, this is like a human ravine, lying on the road of historical progress.

Liu Xuan had already made psychological preparations before the research, but he still didn't expect that in five years, the results of the research were very few, just like Mu Guang said, we are trying to push human civilization to the first level, and the difficulty is not difficult to imagine.

In fact, they have found the right way, but there is a lack of a formula, a universal formula for fission and fusion, according to Liu Xuan's speculation, this formula is mainly to change stable elements into elements that are prone to fission or fusion, however, this formula Liu Xuan has been proposed by Liu Xuan for nearly three years, Liu Xuan has confirmed the existence of this mysterious formula in all aspects, but it can't be found anyway.

In five years, Liu Xuan's credibility has dropped to the extreme, it turns out that when Liu Xuan enters the research room, he can always attract the admiration of a group of researchers, but now Liu Xuan has become the most ordinary appearance, no one admires him, and no one is even willing to be his assistant.

Human beings are like that, that's the reality. When you are full of honor, there will always be a lot of people to slap you, and when you fall into a trough, this group of people doesn't know where they will disappear. What's even more terrifying is that Liu Xuan also heard that behind him, many people are talking about his achievements back then just stealing his father's research results. Liu Xuan was under a lot of pressure, but fortunately, Mu Guang supported him.

The experience of these years has made Liu Xuan understand that the so-called seventh-level civilization they saw back then was just a false name they had put on themselves, and in Liu Xuan's opinion, they were at most a civilization standing at the peak of the sixth-level civilization.

The evolution of all civilizations is not only the evolution of science and technology, the evolution of genes, but more importantly, the evolution of morality.

At that time, when they said "destruction", it proved that they had not passed the moral test at all, this kind of civilization is undoubtedly the most terrifying, they have the power to destroy the universe, but they do not have the top moral constraints of the universe.

Entering the research room, no one paid attention to Liu Xuan, Liu Xuan silently sat back in his place and began a day's research. This is the state that started three years ago, and it has not changed until now.

Get up, leave the house, go into the research room, study, eat lunch, study in the afternoon, go home in the evening, sleep. This has always been Liu Xuan's state of life, Liu Xuan knows his goal, but he still lives a messy life every day.

Since he had a family, Liu Xuan also has a spiritual harbor, but he has no youthful hard work, he does not have the perseverance to soak in the research room all day, how many times, Liu Xuan is thinking about retirement, giving up the future of mankind, but in his heart he feels sorry for Professor Ma's hard work.

Liu Xuan has his own theory, he already knows a lot of things in the research room, human beings bring back all kinds of asteroids in space almost every day, and the mass of the earth has definitely increased a lot compared to a hundred years ago. The construction of a base on the moon and the gradual improvement of the International Space Station are milestones in the conquest of space.

"Liu Xuan, come here, I have good news for you." Mu Guang came out of the office and beckoned to Liu Xuan, Liu Xuan put down the work in his hand and walked to the office, his heart did not have a little wave, he was already a little tired of all this, he was questioning himself all the time, is his direction wrong, is there no chance to cross the wormhole? All he wanted to do now was go home, go back to the surface, find a farm, and bask in the sun's rays every day. Away from the aerospace industry, away from the city full of high-tech, back to the most simple era.

If you really want to talk about it, Liu Xuan has not gone out for five years since he came to the underground city.

When Liu Xuan entered, Mu Guang was looking at the computer screen in front of him with a happy face, the researchers were used to this kind of old-fashioned computer screen, almost no one replaced the computer in the research room with the latest one, and another reason was that the computing power of these old-fashioned computers was stronger than those new-style computers, after all, those computers only changed the peripherals, and did not change the internal configuration.

Liu Xuan also glanced at the computer screen lazily, just scanned the title, Liu Xuan's whole person became energetic, it was an internal announcement, Liu Xuan looked at this article carefully.

After reading the article, Liu Xuan glanced at Mu Guang, and there was excitement in his eyes that could not be concealed. This article is mainly about the latest breakthrough made by mankind in antimatter, and Liu Xuan and others have been waiting for this breakthrough for five years.

"Finally, we have a way for antimatter to fit to the surface of positive matter, so we have a chance to pass through the wormhole!" Mu Guang's old face was also full of joy.

"It's just our technology." Liu Xuan clasped the cylinder left by Professor Ma with both hands, and said happily that he had finally seen the dawn.

"What is this?" Mu Guang saw Liu Xuan's necklace pendant for the first time and asked curiously.

"It was given to me by an old friend." Liu Xuan put the cylinder in the palm of his hand, so that Mu Guang looked more carefully.

"This ...... The pattern on this top seems to be an ancient text. Mu Guang's puzzled voice surprised Liu Xuan.
