Wangu Xian Qiong

Very similar styles of comedy and randomness. It feels like they're very much the same kind of anime however one is japanese and one is chinese. The other difference is of course the budget these had. One is Gintama and the other one is an ONA. 

-Both animes are chinese -Both stories are about cultivation, martial arts and martial techniques -Both MCs are weak at the start but later become stronger -Both MCs are reincarnated/given second chance in life -Male MCs are geniuses and the others are underestimate them -In both stories the powers levels are divided between stages.

The stories are about MCs that are quite knowledgeable in they respective fields (literature, chinese chess) MCs are often underestimated and only a handful of people see how much talented they really are Both MCs have/make some good and trustworthy friends.
