Nü Shi Zunmen Dou Xiang Zhanyou Wo

Xiao Nan died tragically and then isekai-ed to the 21st Continent. Although reborn as useless trash, he awakened the reverse system, and his strength would increase as long as he was hurt. What he didn’t know was that he had a hidden identity-as the chosen son of heaven who was prophesized to revitalize the Sword sect. The elders of all factions in the sect therefore hid their identities and approached Xiao Nan to try to recruit him into their own ranks. Since then, Xiao Nan began to enjoy being nurtured by beautiful female masters, whilst discovering features of the system to become stronger + start a harem. (Source: Kuaikan, translated)
