It's a wild novel, and one of my favorites! Fair warning that this polycule is very not canon, I'm just in multishipping hell!! Also the Shen Qingqiu here is the original person to have that name, not the main character of the book.

This is the English release if you're interested (it's long so the webnovel was split in 4 for the physical English release):
