I Am a Handyman Sweeping the Floor, and I Became Invincible from the Time I Trained an Empress.

Also known as "The Empress I Trained Always Wants to Protect Me" Qin Yu traveled through the world of immortality and became a sweeper. The five elements are useless and the body cannot be cultivated. There are nine palaces in Dantian, corresponding to the nine future god emperors. As long as a candidate for god emperor is found and cultivated, his talent will be improved. First he found Senior Sister Su Rong, and the training direction was Empress Yuanling. Help her advance to a higher realm, and Qin Yu transforms from a five-element waste body into a five-element spirit body. Advance another realm, and a one-star genius becomes a two-star... At this time Qin Yu was invincible. But the senior sister Su Rong he trained always wanted to protect him!
