My Disciple's Cultivation Returns Ten Thousand Times, So I Have to Be Invincible

Because his cheap master was a Taoist, he became the peak master of one of the seven peaks of the Immortal River Sect upon transmigrating. But in reality, it was all useless. This peak master was not only a good-for-nothing, but also had only one little disciple who was still hungry and needed help. Fortunately, there's a bound system. He takes in two useless disciples, activates the bond between them, and turns the useless disciples into geniuses, returning his cultivation a thousandfold. Before he knows it, he's become an immortal.
