Other people's quick transmigration is just going through the motions.
Lin Xing's quick transmigration means truly living.
First world: School life.
The mission is to bring the male and female leads together.
He takes three months to get them together, then spends seventy years watching them live out their lives.
When the System tells him to leave, he's telling the female lead's granddaughter stories about her grandmother's youth.
"Host, you completed the mission ages ago."
"Oh," he says. "Then I'll leave after I finish this story."
Lin Xing really has lived for a long, long time.
So long that he's forgotten what the wind felt like when he fell from the rooftop at seventeen.
So long that the phrase "plot correction" tastes like dust when he says it.
So long that sometimes he forgets: is he Lin Xing, or is he the person in some other world who lived an entire lifetime?
[Plot Correction System monitoring online...]
[Host, you've drifted off again.]
"Mm."
"Remember something?"
"No," he says. "It was probably... a long time ago."
