The Wandering Planet

Qiao Lv originally thought that he would meet someone he didn't know at all. After all, 2,500 years have passed, and he probably knows very few people in the world now, as if he was back when he just traveled to the wandering earth.

However, the world is so strange, waiting for Qiao Lv outside is a familiar figure.

The one who came was Ding Yi. His appearance was not much different from that of Qiao Lv before he entered hibernation, even younger.

The reunion came so suddenly, in Qiao Lv's memory, it seemed that only a few days had passed, and it even made him wonder if it had been so long.

Before Qiao Li could speak, Ding Yi stepped up excitedly and said:

"Qiao Lv! I finally saw you again! I heard that someone invaded here during the rebellion. I was really worried that something would happen to you. Fortunately, it turned out to be fine."

Although in Qiao Lu's feeling, the last time I saw Ding Yi was only a few hours ago, judging from Ding Yi's performance, many years have indeed passed in this world.

Qiao Li nodded and said, "2B helped me drive away the intruders. To be honest, I didn't know anything about it at the time. How many years ago did this happen?"

"How many years ago?" Ding Yi rolled his eyes at him and said, "It was nearly two hundred years ago! In fact, I woke up two months earlier than you, and I only recently found out that this kind of thing happened in history."

Sure enough, Ding Yi also came to this new era through hibernation technology. After all, he also participated in the research of related technologies back then, and he can be said to be an expert in this regard.

"It's been so long, why do you look younger than before?" Qiao Lu couldn't help asking curiously.

"Young?" Ding Yi laughed heartily as if listening to a joke: "I'm over seventy years old! Do you think I've been hibernating for more than two thousand years like you?"

Although Ding Yi pretended to be over seventy years old, she really couldn't tell from the outside, and there was no sign of aging.

Amid Qiao Lv's doubts, Ding Yi explained:

"Nowadays, the average life expectancy of human beings has already exceeded 200 years. This is achieved on the basis that the law prohibits the research on technology to extend life indefinitely. There is no way. Universal immortality is a terrible thing. Even if it is technically possible, Nor is it ethically permissible."

This is like the human cloning technology in the past, there are still certain taboos in science, no matter in the past or in the future.

"Currently the main application is prosthetic body technology. Replacing aging organs with artificial organs is enough for people to live for decades. With a little biomedical technology, the average age of two hundred is just a small thing. It was reached a hundred years ago. However, the coalition government found that such research would be a bottomless pit. If the average age per capita continues to be hundreds of years, society is prone to problems, so it began to legislate to prohibit endless research on life extension. "

Ding Yi then changed the subject: "However, according to the law, the period of hibernation is not counted as age, so there is no restriction on this aspect. I just hibernate intermittently all the way, and only stay in each era for a year or two. After learning that the technology at that time could not meet my requirements, I continued to hibernate until the next era, and it has passed so long before I knew it."

"It's really an interesting experience." Qiao Lu said with a smile.

Even though such a long time has passed, Ding Yi is still the same scientific madman who hibernated all the way to the present in order to pursue the truth of the universe.

Ding Yi complained: "Actually, people have already called me Ding Lao. Obviously I think I am quite young, even if there is a life limit, can I still live for more than a hundred years? I really don't know where I am old." .”

"That's respect for your seniority. I'm afraid your name is now in the history of science."

Qiao Lu guessed right, Ding Yi, in the eyes of today's scientists,

They are all old scientists of the generation of the ancestors, and their respect for him comes from the bottom of their hearts.

Ding Yi jokingly said: "You still have the nerve to laugh at me. When you go out and see how the history textbooks evaluate you, you may be more embarrassed than me."

About this point, Qiao Li was still a little anxious. After all, during the Great Rebellion, he was also criticized as a dictator, a tyrant who killed countless people. So how society evaluates him today, even if Moss said he has been rehabilitated later, he is still a little worried.

"Anyway, let's go out and talk about it first. The society has changed a lot. I'll take you for a walk." Ding Yi suggested.

In any case, after all, it is necessary to take this step.

Qiao Li looked back at the room where he was sleeping. Moss was controlling the machine to tidy up, bringing everything back to its original appearance. This is probably the reason why the entire area has remained unchanged for 2,500 years.

"Moss, I'm leaving, do you want to come with me?" Qiao Lv said to this faithful artificial intelligence.

Moss replied: "No, I will stay here forever. If you find that this era cannot meet your requirements, you can come back to continue hibernating at any time. The door here will always be open for you."

"Thanks."

In this strange era, there are still a group of people who are silently supporting themselves behind the scenes, which is really extremely lucky.

After bidding farewell to Moss, Qiao Lu took 2B and Ding Yi to the elevator to the surface. It can be seen that this elevator has been renovated, and it may have been more than once.

It used to take more than 20 minutes to descend all the way from the surface to here, but now it takes less than a minute for the elevator to reach the ground.

When the elevator door slowly opened, Qiao Lv really couldn't recognize that this was the wandering earth that used to be. Sure enough, the times had changed.

What greeted him was a golden wheat field, extending all the way to the end of the horizon, full of ears of wheat fluttering in the wind, without any trace of industry.

Qiao Lv looked back at the place where he came out. It was just a simple cabin on the wheat field, covered in the golden ocean, and he couldn't see it unless he got close.

But this is the only building within a radius of one kilometer, and there are no other high-rise buildings, which are very different from Qiao Lv's memory.

"How did it become like this here? What about the Central Academy of Sciences?"

"It has been moved to space a long time ago." Ding Yi replied, "Most of the industries on the earth are now transferred to orbit and run in the form of a space city, and the Central Academy of Sciences is the same. The earth is mainly a residential area, and now entering space is a It’s as convenient as taking the subway. So people in this era live on Earth and work in space.”

This is indeed an unimaginable way of life for Qiao Lv, but it is precisely because of this that a beautiful golden wheat field has been left on the land that was originally the Central Academy of Sciences. .

"The changes are not limited to these, let's hurry up." Ding Yi urged.

It seems that this is indeed not a bad era. Perhaps there has been a detour, but now mankind is back on the right track. This is probably how history moves forward.
