Cultivating Disciples to Breakthrough Novel

Xuan Hao awakens in a cultivation world after transmigrating into the body of a Flying Sword Sect elder at the Nascent Soul Realm—powerful enough to level cities with ease. His unique system grants him strength based on his disciples' advancement, pushing him to cultivate talented students. After successfully guiding his disciples to Immortal status, Xuan Hao hopes for respite. Instead, his system demands more: four disciples must reach the Dao Immortal Realm, promising him a major cultivation breakthrough as reward. Exhausted by the escalating challenges, Xuan Hao contemplates abandoning further progress. His disciples prove far less obedient than expected, and strange changes plague the sect. Most baffling of all, newer disciples have begun addressing him as "great ancestor" despite the elderly Sect Master still being alive and his senior. How did he suddenly become the sect's ancestor?
