Chen Can received a letter with only one sentence in it
"If you climb high tomorrow, please tell me - we have never been apart."
The person who wrote the letter is called Li Pi. He is Chen Can's brother or lover. He is already dead.
System 2552 appears and tells him: Li Pi's soul fragments are walking around in different galaxies. He can find them, but they can only stay in each galaxy for 24 hours. If it times out, he will stay in that galaxy forever, and everything in the original world will be replaced by a new one.
He did not hesitate, traveling across the galaxy, collecting fragments, like collecting scattered jigsaw puzzles, and putting the pieces together step by step.
But he didn't know that Li Pi had already written the ending for him before he disappeared.
The last page is blank and was written by Chen Can himself.
Intention: The meaning of searching does not lie in the arrival after searching, but in the burning itself during the searching.
If you climb high tomorrow, please tell me - we have never been apart
