Lost in the Golden Age: a History Graduate Student's Journey Through the Tang Dynasty

My World, Transmigration and Rebirth, Equivalent Exchange

I’ve noticed that most transmigration stories on Fanqie don’t dare to tackle equivalent exchange. The subject matter, content, and setting are hard to write, and with all the time jumps, timelines, and huge worldbuilding, the story usually falls apart unless the writing is really good. Are there any good books about equivalent exchange?
