Stepping on the slightly wet grass in the morning, Hatsu and B3068 stood on a hillside.

"You're really up to the mark?"

Hatsu asked next to B3068.

B3068 looked up, looking up at the sky, or possibly at the endless starry sky beyond it, looking up at the direction of humanity's departure.

"Didi. "Its rudimentary electronic audio doesn't speak a full language, but sometimes it doesn't need that many languages.

It has already made a decision, and the next step is to act towards that decision, which is simple and straightforward, and does not require any other choice. As a robot, that's what it does best.

Chu didn't say anything more to B3068, she watched as B3068 raised his hand, pointing the old and broken metal palm against the clear sky.

The palm of his hand began to collect air samples, and B3068's eyes were brighter and brighter in pale green anticipation.

It looks forward to its mission, it looks forward to the return of humanity, it looks forward to the planet that will no longer be broken, and it looks forward to the day when everything changes.

It shouldn't have been too long since the test data appeared on B3068's arm.

It carefully checks the data on the display to confirm that every character is accurate.

The dilapidated robot stood in place for a moment, then seemed to smile.

It sat down briskly and held its arm in front of Hatsu.

At first, I didn't know what kind of data was up to standard, but B3068's actions have said it all.

After passing the test, as an EDR robot, what B3068 has to do now is to signal the return to humans.

It didn't do that for the first time, though, because before that, there was a small celebration between it and Hatsu.

B3068 pulls out a tape from the chest compartment, examines it carefully, and puts it into its reader.

It was the first tape it had ever listened to, the song under the stars, and the song had never been indispensable for the celebration between them.

Although on dull days, they have rarely celebrated anything.

Probably because so much time had passed, the equally old tape had only a few faint sounds in the reader, and then it had lost its sound.

B3068 scratched its head helplessly, it had some regrets, because this was the last time, and it had hoped that it would have gone well.

Chu smiled slightly and sat down next to the robot.

She looked earnestly into the distance, as if in her ears, the song had already sounded.

So B3068 looked at the beginning, and at the beginning of the blue sky in the distance, it was as if he had returned to the starry sky that day, the messenger looked up at the Milky Way, and the robot only looked at the messenger.

There was silence all around, only the wind rustling the blades of grass.

After a long time, Chu said.

"It's good. ”

The song is good, the sound of the wind blowing through the blades of grass is good, and the sound of the world is good.

Yes, in the silence, it seemed that something could be heard that touched the heart.

B3068 also fell silent, and it sat silently.

After a while, it scratched its fingers nervously, hesitated, and took out another piece of paper from its storage box and handed it to Hatsu.

This is what it has prepared, a gift for the first goodbye.

Chu looked down and saw that it was a painting.

There is a beautiful world in the painting, with sky, clouds, meadows and rivers.

A dark-haired girl is standing in the middle of the painting with her hands behind her back, in the middle of that world. She looked back at the outside of the painting with a shallow smile on her face.

The girl looked very similar to Hatsu, but there was no scar on her face, and her smile was bright, like the sun in the sky.

This is the most beautiful world in the eyes of B3068, has it seen it with its own eyes, it has seen it with its own eyes.

"For me?" Hatsu asked.

"Didi. B3068 nodded.

"Thank you. Hatsu took the painting from B3068's hands.

She accepted the gift, but she didn't say that she couldn't take anything out of this world, not even a painting.

With all that done, the B3068 put up the transmitter on its shoulder, and it should be doing its last thing.

It records the location of the landmark, and then enters the signal into the transmitter.

Detected, suitable for the environment.

The transmitter lifted, and under the watchful eye of B3068, the signal was shot into the endless sky, illuminating the long journey home.

B3068 finally sent its best wishes to this not a good world.

with its life.

As the signal came out, the green light in the robot's eyes gradually dimmed.

In the last moments of its life, it carefully stretched out its hand, little by little, and gently grasped the palm of the first hand.

Chu lowered his eyes and slowly took his hand in his hand with his backhand.

“3068。 She asked at the robot.

"Are you still lonely?"

B3068 has no way to answer, most of its systems have begun to shut down, but it has the answer in its heart.

It was not alone, it was saved when it first stretched out its hand to it in darkness and silence.

With this answer, in silence, B3068's programs were closed one by one, and the originally clear world gradually moved away from it, and it slowly closed its eyes.

And around it, the world in front of it is slowly becoming clear.

Even the sin that gradually poured out was no longer the chaos and darkness that it was.

When the black mist of sin shrouded the grass green, Chu Jing sat there, letting the black mist pour into her body.

Just as B3068 naturally chose to let humanity come back, it was a natural choice to bear the sin at first.

Not because she had to, but because she was willing to do it.

Because she's a villain who came out of the corpse, because she's the most sinful of human beings, isn't she?

She wants to atone for herself.

If there is no so-called sin in this world, if sin can be taken away, if there is a person who is willing to carry all sin on his back.

What would the world be like?

When the black fog dissipates, will the light that symbolizes hope return?

I didn't think about this at first, because these had nothing to do with her, what she had to do was to carry all the darkness before the light appeared.

After a long time, the black fog on the grass dissipated, and the first figure also dissipated.

The painting, which depicts the most beautiful world in the robot's heart, gently floated to the ground.

The robot sits alone, looking up at the distant starry sky.

It is like a lifeless sculpture, but it is also it, giving new hope to all life on this planet.

Whether the humans came back after that, no one knows.

I only know that the next day, the sun is shining on this gray-green planet.
