My Clan Thrives on My Investments

A man wakes up in the body of Memphis, the head of the Mu clan, who is dying. A system attaches to him at that point. It works one way: he assesses a clan member's talent, puts cultivation into that person, and gets back more cultivation than he put in. The first is a nephew the clan had written off, who is carrying the remnant soul of a venerated cultivator. There is also a boy who has just awakened a system of his own, and a reincarnated emperor whose power is about to tear him apart, whom Memphis pulls out of it and binds before investing in him. The Ethereal Sect comes to the Mu house to call off a betrothal and says it will wipe the clan out. Memphis leads the younger members of the family against them and puts the sect's party down. He keeps investing after that, and the clan starts turning out emperors of its own.
