When a civilization breaks through the technology that determines the level of civilization, it sends a signal to the world, as if announcing to the world which level we have reached.

This signal appears inexplicably, so inexplicably that repeating the exact same experimental process again will not appear again.

Di Yi believes that this is not accidental, because the civilization they were in before and the current Emperor Luo have detected this kind of signal.

This should be a kind of cosmic rule?

Di Yi didn't dare to make a conclusion, after all, the object of his observation was only his original civilization and Emperor Luo.

But Li Shitang is completely sure that his guess is correct.

Because so it was with Turing, so with Yahweh, and so with the earth.

The specificity of civilization is not limited to this, there are other manifestations.

All civilizations that have left their home planet will experience reduced fertility.

Di Yi is very sure that their civilization has already entered the interstellar age, and interstellar exploration is in full swing, when low fertility is not taken seriously, because most people are still used to having children on their home planet.

But the Emperors are different, they have left their civilization and come to a new planet.

At that time, there were as many as 400,000 emperors who came here, but with the slow decline of fertility, only 4,000 of these 400,000 people were left after 6,000 years...

No wonder the book was treasured by the Queen, and no wonder it couldn't be found in the library outside...

If this book is spread outside, it may cause social unrest, popular unrest, in an instant.

But after the riots, there will be local residents of the emperor who will take the political stage and take the place of the emperor, because the emperor is a group of people who are doomed to perish.

But the Emperor will not easily let go of the rights in his hands, so this book will only circulate in the hands of the Emperor and will never be passed on to the outside.

But civilization has come to this point, and it is about to be destroyed, and Dixi has no idea of secrecy, so he just puts it on his desk casually.

Li Shitang felt extremely frightened when he looked at it, Turing still didn't understand what went wrong with them, causing six million remnants to die in three thousand years.

And the earth was also going to leave by spaceship, if it weren't for the fact that they couldn't make a spaceship that could transport so many people away in 20 years, they wouldn't have driven the earth away directly!

If this had been done at that time, then those who remained on Earth would have died, and those who escaped from Earth would have died!

Li Shitang is completely immersed in this book, Di Yi's writing is not as formal and official as ordinary popular science literature, but all kinds of interesting metaphors and jokes come at hand, so that Li Shitang only feels relishish when he reads it.

Although a large amount of space is full of speculative words: maybe, probably, maybe, etc., but after adding Li Shitang's experience, many conjectures will have a definite answer here in Li Shitang.

The great sense of accomplishment and satisfaction of human beings after living new knowledge is the driving force for human beings to continue to move forward and learn.

In Li Shitang's place, the sense of accomplishment and satisfaction of solving puzzles is the same as the excitement of those crazy fans after getting their idol's private information.

A cup of steaming coffee was gently placed on the table, and as soon as Li Shitang raised his head slightly, he saw Yu Xixi sitting quietly next to him.

"Why are you here?" Li Shitang asked in surprise.

Yu Xixi smiled: "Xiaoshi sent me over..."

Li Shitang was silent, what he asked was why you came over...

Yu Xixi also understood the question, but her answer was difficult to say.

She felt like her time was running out.

Children and grandchildren have their own things, and the only one who can accompany them is their husband...

But he, alas, doesn't say anything...

Li Shitang suddenly had an idea, and his spiritual power probed towards Yu Xixi's body.

He naturally didn't have any strange thoughts, after all, he had been a husband and wife for decades, so how could there be any secrets.

He wanted to use Yuan Li to stop Yu Xixi's aging.

The aging of the human body is caused by free radicals colliding with telomeres, resulting in shortening of telomeres and reducing cell lifespan.

But the meta-force can hinder this process and at the same time destroy the free radicals that DNA is constantly producing.

As long as Li Shitang uses Yuan Force to destroy the free radicals in Yu Xixi's body, Yu Xixi's physiological state will always remain at this level.

He hadn't done this before because Yuan Li couldn't leave his body at all, but now he could.

However, as soon as Yuan Li came into contact with Yu Xixi's body, Li Shitang's face sank.

His Yuan Force was like crashing into a mountain, only he was stunned, but the mountain didn't move.

"What's going on?" Li Shitang asked in a deep voice, didn't he use Yuan Force to scan the body structure of those natives in the other world, and there was no such problem at that time!

"Rejection!" Xiaoqing replied.

"That's obviously okay in other worlds..."Li Shitang retorted.

"The power level of Yuan Li is very high, and I can't completely analyze it now, but don't you think that Yuan Li's performance in this world is much worse than in the world after crossing over?" Xiaoqing asked quietly.

This world is suppressing not only the scope of the Yuan Force, but also the level of the Yuan Force!

Holding back the sorrow in his heart, he picked up the coffee on the table and stirred it a few times, then took a sip.

Like it was done countless times many years ago.

"You deserve it?" He asked softly.

Yu Xixi nodded: "How does it taste?" ”

Li Shitang shook his head: "It's a pity that I still like others to be good..."

Yu Xixi couldn't help laughing: "The magpie's nest was gone decades ago, who do you find to match you?" ”

Li Shitang also shook his head: "Then do you think I am now a red-sleeved fragrance night study?" ”

Yu Xixi shook her head: "There are no red sleeves either, there is only a pale face and white head here..."

She also wants to live forever, but Li Shitang can't do anything...

This is not another world, and he is just an ordinary person with a little bit of strength here.

"The fifth-level civilization has genetic technology, and when the time comes, I will put your body in a place where time and space stand still. When we reach the fifth level, I will resurrect you, and then we will live forever together! Li Shitang took Yu Xixi's hand and solemnly promised.

Yu Xixi nodded: "I hope so..."

When Li Shitang saw this, he always felt sad, and as soon as his heart moved, a ball of blood began to appear in the inner world, while Li Shitang in the outside world was aging at a speed visible to the naked eye.

He drained the blood qi with the help of Iwasawa!

He couldn't do it at all, but now...

I can finally grow old with you.

"What are you reading?" The two old men held hands and took a selfie for a while, Yu Xixi asked.

Naturally, she couldn't read Emperor Luo's words.

Li Shitang put down "Civilization" and picked up the poetry collection of Di Kangqing.

"Why don't I read it to you?"

Yu Xixi nodded.

Li Shitang coughed his throat, accompanied by the faint light of the artificial sun in the Emperor's Mothership, the mellow voice with the precipitation of these years slowly sounded.

The first time I saw you, you were drunk in my arms

See you again, I'm drunk in your life
