Siheyuan: After Signing In, I Collected Cards of the Goddesses

(The early part of this book is rather low-key and focused on daily life. The pocket dimension will level up later, and the romance starts after chapter 90. Please don't read if that bothers you!)

The protagonist, Li Jianguo, transmigrates into "Love in the Courtyard" and obtains a sign-in System. Step by step, he turns the courtyard into his own backyard and becomes its uncrowned king.

He never lets himself be taken advantage of, keeps his temper in check, sets the courtyard's troublemakers straight, and wins over beautiful women. Anyone who doesn't deserve to die survives, and everyone gets the ending that suits them best. The protagonist makes the courtyard his home, gathers supplies, builds connections, and thrives in the capital.

A note about the protagonist's age: he was born in 1943. When the story begins, the actual date is January 13, 1962, the eighth day of the twelfth lunar month. In many places, people didn't count age from January; they added a year only after the Lunar New Year. So if you see a passage saying the protagonist is still 19 after the new year, don't be confused.
