Hing Jian is the most inconspicuous clerk in Si Tian Jian San Shi Ke.
That night, he was on duty at the observatory. The sky opened and a man covered in blood fell from the sky. The man said that his name was Qin Yan, that he came from the ancient country of Loulan eighty years ago, and that he had drifted in the cracks of time and space for eighty years, just to go back to the past to save his sister.
Qin Yan needs three star chart fragments to activate the star trajectory retracement array.
Shen Xingjian helped him find the first piece. There was a small red dot on the fingertip. Qin Yan said it was called a star mark and would erode the memory.
The second piece is hidden in the ruined tower outside the city. There is a translucent girl in the tower, who is the soul of Qin Yan's sister. She smiled and said a prophecy: "When the formation is activated, one person will return, and one person will be lost forever."
Shen Xingjian didn't tell Qin Yan that he understood.
The third piece is in the snout of the highest owl at the observatory. When he got it, the armillary sphere rotated on its own, and the four star orbits resonated. Shen Xing saw that the blue lines on the palm of his hand had spread to his wrist.
Qin Yan said that the formation would choose the person with the deepest resonance to sacrifice. Shen Xingjian touched three fragments, and the mark was the deepest.
"How long will it take before I don't remember anything at all?"
"Three months."
"That's enough. Three months is enough for you to put the pieces together into a formation."
Qin Yan said no. Shen Xingjian said, let me think of it myself.
Later Shen Xingjian really forgot. He doesn't remember Qin Yan, he doesn't remember the star map, and he doesn't remember why he goes to the stargazing platform every night.
But when his fingers touched a mark on the stone fence, tears fell for no reason. The mark is in Loulan script, with one word written on it——
"Qin".
There is a time when the stars return and there is a time when we meet again.
Intention: To sacrifice oneself and forget oneself, to fulfill what one loves
