In the year 491 of the Stellar Era, in the DX3906 galaxy, outside the Black Domain, a small ship stopped.

The ship glides slowly and crashes into the Black Domain to avoid being destroyed by being too fast when entering the Black Domain.

The arrival of the extraterrestrial visitor attracts the attention of the dawn.

Tomoko sets off from an asteroid outside the Black Domain to scout for information.

In the cockpit, Yun Tianming wrote the information he wanted to send, and wrote down a few hundred words freely, but he felt that it was inappropriate, so he deleted it.

I picked up the pen several times, but I just couldn't write anything that satisfied me, "Forget it, forget it, at the speed of light in the black field, it will take three or four years for the spaceship to reach the Blue Star..."

"It seems like a good idea to appear in front of her out of nowhere and surprise her."

Yun Tianming put down his pen and waited for the spaceship to enter the black domain.

At this time, he saw a line of text, which was an unusually familiar Chinese character: Please wait.

"Tomoko? Is that you? ”

The moment he asked, he decided that this was not Zhizi, and the three-body man should not follow him.

After all, I really don't know anything.

"No, I'm Dawn."

Yun Tianming was stunned for a moment, and said with a smile: "I have admired the name for a long time, Ms. Shuguang, are you waiting for me here?" ”

As he spoke, he activated the spacecraft's fusion engine, thrusting back against the star's weak gravitational pull.

"My main mission is to stay in the DX3906 galaxy and observe the interstellar lanes not far away," Dawn said. ”

"It's just a matter of passing by that waiting for you, because it's unknown whether you'll be here or not."

"Understood, what do you want to know?" Yun Tianming doesn't talk nonsense either, and goes straight to the point.

"Where is the new world of the Trimaran First Fleet?"

"To be honest, I don't know."

Yun Tianming tapped his head with his finger, "The relevant memories have all been deleted." ”

It's easy when you fully understand the structure of the human brain.

"The Trisolarans won't bet on my loyalty, so naturally it's impossible for me to leak information about them."

In the dark forest, any factor that may expose himself should be extinguished, and Yun Tianming, as a human being, can leave the Three-Body Civilization alive, which is enough to prove how much the Three-Body People respect him.

After analyzing it for a moment, Shuguang asked again: "Can you let me read the range data and database of this spaceship?" ”

"Of course you can, but it can't let you trace the coordinates of the new world of the three-body civilization backwards, because I entered the big universe from the small universe, and the source of the spaceship's route is an empty interstellar space."

Yun Tianming asked with a little curiosity: "Do you want to avenge human civilization?" Is it by order of the coalition government, or is it your own will? ”

Shuguang replied truthfully: "The main reason is pan-human, you should know, right?" ”

"Well, you know, great ideals, but not realistic."

"If you don't chase it, how can you know that your ideals can't be realized? Therefore, I need to collect all kinds of powerful technologies, and the search for the Three-Body Civilization is also to obtain the super technology they have mastered. ”

"It does not meet the conditions of pan-humans, and they are still hostile to pan-humans, and then destroy them, which is only incidental."

"If the three-body civilization is willing to change itself, I don't need to destroy them, everyone is a bug, and only the united worms can pull the god civilization down the throne and change the heavens and the earth."

Yun Tianming shook his head: "I understand, but I don't think that the current you, human civilization, have the ability to change the order of the universe." ”

Dawn didn't answer, and she quickly decoded the data, and the source was indeed an interstellar desert.

She said regretfully: "What a pity. ”

"I see a box made of thin glowing lines next to you, what is it?"

Yun Tianming smiled slightly: "The door of the small universe." ”

"It's impossible, but I still want to ask, can you give it to me? I need a sample reference. ”

At this point in time, it was not long before Dawn cloned the Trisolara, and it had not yet ushered in a technological explosion.

"Forgive me for refusing."

Dawn didn't dwell on it either, "Okay, goodbye." ”

……

Three years later, Blue Star, Cheng Xin, who is more than 300 years old but still young, is working in the paddy fields and harvesting rice.

After two hundred years of transformation, the vitality of the blue star has become more vigorous than before, and the flora and fauna are everywhere.

A dazzling meteor suddenly appeared in the sky, and Cheng Xin looked up, the scale was too large, and it didn't feel like a satellite had fallen.

"Dawn, has the observatory fallen?"

It was the last surviving large space station in Blue Star's low-Earth orbit, and its main function was to observe the stars.

"No, let's go and have a look." Dawn sends out an invitation.

Cheng Xin refused: "If it's just a meteorite or the wreckage of a space station, forget it, it's still important to harvest rice." ”

Dawn: "Leave the harvest to me, let's go and have a look, maybe there will be a surprise." ”

As soon as the words fell, Cheng Xin heard the sound of breaking the sky caused by the high-speed movement of the propellers of the large aircraft.

A transport plane soon hovered overhead, and the strong wind blew the fields full of rice and bent their waists.

Dawn controlled the android to throw down the rope ladder and waved his hand to signal Cheng Xin to come up.

Cheng Xin looked at the transport plane, this was Shuguang's decision made independently, and he didn't call the plane over.

Shuguang made decisions independently, and after more than 200 years of getting along, Cheng Xin had never met a few times.

Something important or strange should be.

Driven by curiosity, she put down the sickle in her hand, handed over the rest of the work to the smart rice harvester, and then climbed cleanly up the rope ladder to the transport machine.

In the large transport cabin, she saw her wardrobe and dresser, and couldn't help but ask suspiciously, "Huh? Dawn, what do you bring them up for. ”

"Keep it a secret for the time being, and the surprise will be saved for the end."

Shuguang said while pulling Cheng Xin to wash, you can't use the image of a peasant woman to face your lover, right?

The transport plane soon arrived at the place where the spaceship crashed, and Cheng Xin, at the suggestion of Shuguang, changed into a beautiful everyday outfit.

Standing at the door of the transport cabin, looking down at the wreckage of the spacecraft with billowing smoke in the huge crater, thinking of the surprise in Shuguang's mouth, Cheng Xin realized what the surprise was, and she said anxiously:

"It's a ship!? Is he coming! ”

"Hurry up, send construction machinery to the rescue."

Dawn whispered, "No, he's safe." ”

Hearing this, Cheng Xin felt a little relieved, but he still couldn't help but look around, as if he was looking for traces of the escape cabin.

Suddenly, a shimmering square frame passed through the steel plate and burrowed into the belly of the transport plane, the light emitted was not strong, and it was not visible to the naked eye during the day, but the camera of the dawn still caught it.

When Cheng Xin was still looking around, Yun Tianming had already come out of the small universe.

Looking at his lover in front of him, Yun Tianming was stunned for a moment, and then asked softly, "Are you okay?" ”

The voice was very slight, and Yun Tianming didn't know if Cheng Xin could hear it in this noisy environment.

But judging from the reaction of the other party, it should have been heard.

Cheng Xin turned around in a daze, it was him, it was really him, as young as himself.

The hatch then closed, and Shuguang intimately activated the silent mode, and flew home slowly.

Cheng Xin, who was crying with joy, suddenly lost his reserve, and trotted into the man's arms in a few steps.

"I'm sorry, I'm sorry, I was—" she sobbed as she confessed.

Yun Tianming comforted: "It's okay, it's okay, it's all over, thank you for being willing to wait for me for four hundred years." ”

……

After his emotions stabilized, Cheng Xin asked curiously: "Tianming, why did you suddenly appear behind me, magic?" ”

"Of course not."

Yun Tianming pulled Cheng Xin to the box, took her hand and reached in: "Don't be afraid, it's okay." ”

The hand and a section of the forearm disappeared after passing through a certain place, and he couldn't even perceive their existence, Cheng Xin looked at the arm from the other side curiously, and found that the section of the forearm was like a human slice, and the bones and tendons were clearly visible.

She was amazed until Dawn lowered the brightness of the cabin's lights and saw the shimmering frame.

"What is this?"

"The door, the door to the small universe."

"Small Universe!" Cheng Xin was extremely surprised.

She knew what the small universe was and what it meant, so she was surprised.

Cheng Xin asked: "Does the Three-Body Civilization not only have the ability to create a small universe, but also have the ability to mass-produce a small universe?" ”

Yun Tianming nodded and said, "Yes, this small universe is something I ordered, number 647." ”

Cheng Xin thought of human civilization, and the government had invested a lot of resources in the study of the small universe, but there was no gain.

Of course, that was a long time ago, and now, there may have been a breakthrough.

I hope there will be a breakthrough, with a small universe, human civilization can get out of the dark forest of the big universe.

Looking at Cheng Xin, who was a little distracted in his arms, Yun Tianming confessed softly: "Are you willing to accompany me through the end of the universe?" ”

"What? I don't quite understand. ”

"The small universe has an independent timeline, and the ratio to the time of the large universe can reach 1:1 billion, and after living in it for more than ten years, we can see the end of the universe and the rebirth of the universe."

Cheng Xin nodded knowingly and replied: "The Zero Vicky point and the Big Bang will erase all memories, and I want to bring part of the memories of human civilization to the nascent universe." ”

Yun Tianming smiled: "Then when you agree, let's go, go and take a look at our universe." ”

Cheng Xin nodded, and was about to set off but remembered one thing: "You won't come and go back and forth, right?" ”

One second in the small universe is a billion seconds in the big universe, a total of 31 years.

Yun Tianming said: "Of course not, the time of the small universe is adjustable, and I heard that it belongs to the power of the ten dimensions. ”

"There is a high-dimensional structure in the small universe!?"

"It must exist, after all, it is the universe, but we will never see it, the Trisolarans have installed a secret system."

The speaker is unintentional, the listener is intentional, and the dawn of silent listening is planning, how to come to the small universe.

With a sample, it's much easier to study.

"Dawn, do you want to go to the small universe to see?" Cheng Xin asked suddenly.

Shuguang shook his head: "I can't go, the computing power of the bionic carrier chip is too low to carry and run my program." ”

In the low-speed black domain, the carrier of Dawning is mainly an optical path computer, and the minimum requirement is a tree-level supercomputer.

She can now only control machinery remotely.

"Tianming, let's go in like dawn in a few days, shall we?"

Yun Tianming nodded and said, "It's all up to you." ”

……

Before moving into the small universe, Dawning arranged a honeymoon trip for the couple.

The two are like couples in old times, traveling together, climbing together, skiing together...

Blue Star is big, what do you want, the two of them have a lot of fun.

An amusement park full of people (androids), two people eat ice cream and watch the sunset on the Ferris wheel.

Under the light of the sunset, Cheng Xin proposed: "Let's watch a movie together!" ”

Yun Tianming said dotingly: "I have a movie created for me by the Three-Body Civilization to imitate human civilization. ”

"You have all the excellent works of human civilization since the birth of film art, let's choose some by ourselves."

Cheng Xin nodded, tapped his fingers on the table in front of him, summoned the dawn, and began to retrieve his favorite movie.

Shuguang said: "The lives of the two of them can actually make a wonderful realistic movie. ”

"Especially you, Mr. Yun Tianming, as a spy of human civilization that broke into the three-body world, it is already a mythical story that you can come back alive."

Spy? Yun Tianming looked at the projection of the dawn like a scrutiny, are you reminding me of something?

As a spy of human civilization, I am not qualified and have not made a substantial contribution to human civilization.

Yun Tianming looked out the window, although he couldn't see it with the naked eye, he knew that the door of the small universe was next to it, and in order to be able to enter the small universe at any time to take refuge, this door was in follow mode.

The only thing I brought out from the three-body world is this small universe, which is useful for human civilization.

But... It is impossible to give it to you.

"Your experience, the details of it, not even my computing power can simulate it."

Cheng Xin smiled softly and said, "Shuguang, of course you can't simulate it, after all, we don't know anything about the Three-Body Civilization." ”

She looked at Yun Tianming affectionately: "He is the only one in human civilization who has come into contact with the entity of the three-body civilization. ”

Yun Tianming smiled and said, "I forgot it, it's the same as not having contacted." ”

"Let's look at the fairy tales, the label says, adapted from the fairy tales I wrote, but I forgot them."

Yun Tianming uploaded the selected films to Shuguang's database, and Shuguang asked, "Do you want an open-air cinema, an indoor cinema, or a virtual world." ”

"I can do it all, it's up to you." Yun Tianming said dotingly.

"The open-air bar is the most aged."

Shuguang said: "It's going to be dark, it's very suitable, I'll go and arrange it." ”

Compared with Yun Tianming's decisiveness, Cheng Xin was very hesitant in his choice and didn't know what movie to choose.

Those golden age movies always reminded her of human civilization.

Love, friendship, ideals, faith..., what a beautiful thing.

She shuddered at the thought that these good things would pass away with the passing of the universe.

The universe is so unforgiving.

In the nascent universe, will there only be me and Yun Tianming left?

Impossible, impossible, sooner or later human civilization will be able to master the technology of the small universe.

There will be many people who will travel to the nascent universe, and in the pastoral age, those heroes who embrace the ideals of pan-humanity will establish a cosmic just order and destroy the terrible dark forest...

But before that? How many people will die?

Cheng Xin remembered the coordinates marked on the starry night two hundred years ago, and later she knew that it was the coordinates of a fleet graveyard, and more than 500,000 people died so that only a few hundred remained.

It's too dark, it's too cruel.

How many fleets will be destroyed and how many more will die before the birth of the small universe?

If you look at the entire universe, how many lives and civilizations will be destroyed before mastering the small universe.

It's too dark, it's too cruel, and billions, countless lives have died like this.

But..., what does this have to do with me, I'm just a small person, and I'm not qualified to decide their fate.

Cheng was full of thoughts, his fingers slid casually, and a movie poster suddenly came into view.

"In times of crisis, there is only responsibility..."

"Responsibility, responsibility." She muttered silently, repeating these two words, "..., small universe!" ”

"If Dawn can master the small universe, then at least the civilization that meets the conditions of pan-humanity can be saved..."

"How can we be so selfish! How can we travel to the nascent universe alone..."
