Siheyuan: Shagen's Rise to the Top

At night, the protagonist, Niu Gensheng, works part-time as a delivery driver. After rescuing an elderly man who jumped into a river, he transmigrates into the world of a 1955 courtyard compound.

At this point, Silly Zhu is just twenty years old, Qin Huairu has been married into the Jia family for only two years, and Xu Damao is seventeen.

The protagonist is reborn into the body the old man had seventy years earlier.

Niu Gensheng is twenty, an orphan, and a fitter at the Lou Steelworks.

The old man has lost all hope, but is grateful that someone was willing to risk his life to save him at the last moment. He willingly gives up this chance at rebirth and returns to the underworld, leaving the protagonist all the memories of his life.
