This novel is a spin-off of "Yangzhou: The Spring Breeze Is Not as Good as You"
At the end of the Ming Dynasty and the beginning of the Qing Dynasty, the ship sank. When Liang and Sui woke up, they were already in Yangzhou more than three hundred years later. Penniless, nothing.
Liang robbed the first person who passed by - the man's surname was Fang. He spoke little and had quick hands. He pinned him to the ground in three seconds. After being almost beaten to death as a child trafficker, Ryo and Sui were "taken in": they were given food and shelter, but they had to work. Liang joined the project dispatch department as an intern and was under the supervision of Lin Pianpian; Sui was sent to a junior high school as a loan student. She was so good at Chinese that it was scary, but she was so bad at math that she could fill the paper with wheat ears.
There are two time travelers living downstairs, and two "seniors" living upstairs. Lin Pianpian is a culinary killer who knows no difference between salt and sugar, while Fang Qixin is an expressionless rule-maker. Liang doesn't know anything - he can't use a microwave, a printer, or Excel. The only skill he's good at is banned. Sui uses her 14-year-old body to crush the entire grade, while protecting Liang from being targeted by various strange women.
A family of four started living again in Yangzhou three hundred years ago.
