The Omnipotent Servant

Qin Jiang was accidentally electrocuted while taking a bath and traveled back to ancient times and came to Goddess Palace. As an inferior servant, he helped the people there invent perfumes and run a pharmacy with modern marketing methods. Facing Ren Qiusheng, a highly educated doctor who is also a traverser, he is not afraid at all and used his ingenuity to protect the three goddesses.
