Ten thousand times return, the game started with being picked up by the senior sister

Zhao Mu traveled through time and space as a errand disciple of the Shengyuan Demon Sect, and awakened the ten thousand times return system. As long as you pay, you will be rewarded. At the beginning, he helped the senior sister to practice, returned the Red Sun Holy Body, and became a hot commodity in the eyes of the senior sisters. He taught and taught, returned the top level of understanding, and the efficiency of practice improved by leaps and bounds. Even the Queen of the Demon Sect treated Zhao Mu as a guest of honor. My dear brother Zhao, I need you to help me practice! Senior sister, please respect yourself, I am a serious person!
