It's like separate short stories, each world is not connected, it's like characters that are not in the original work have changed some plots, and I don't know what I'm talking about.

The number twenty-two is just a random thought, and it is impossible to write as many stories as twenty-two.
What I can think of so far is as follows
A slight smile is charming, Tang Miao cp The Legend of Foolish Old Man and Lu Xiaofeng, Zhu Mingyao cp Lu Xiaofeng Detective Conan, Akiyama Yu cp Gin, etc.
