Slapped the Sect Master's Secret, Destiny Ours

Modern youth Luo Yin accidentally travels to become the useless senior brother of a sect who hasn't broken through in seven years. After discovering the sect master Ling Qingxue's secret of being a woman, he activates the Fate Deduction System. He steals the protagonist Su Chen's opportunities and intercepts the luck of various talents, rising from a body-hardening waste to recruit Liu Qingchan, Ling'er, and a group of fierce generals and strategists. He endures the sect's grand competition and the Xuantian Tower trial, fighting powerful enemies like the Demon Heaven Sect and the Blood Nether Tribe. He strips other transmigrators of their systems, eventually controlling the Heavenly Dao to protect those around him, achieving a counter-attack to become the supreme ruler of the three realms and rewriting his fate from becoming a villain's dog.
