Waste of Time, story could have been good if not for a lot off discrepancies, MC reincarnated to save the world with big power in play and battle and waste his time to f*ck left and right, start with pseudo moral to not do this or that and do it a few chapters later with stupid reasoning. Book for horny kid that like NTR, Incest, Anal, Golden shower and co. Sadly author put more effort into his own degeneracy than the story. Don't waste your time. 

Waste of Time, incest, stupid MC with stupid plot, useless Harem impossible to remember with chineese name. Poor writting. MC Ego is bigger than universe.
