Uncle Nine: I Have a Disciple-Recruiting System

A modern young man transmigrates into Shi Shaojian. After coming down from the mountain, he saves an old Daoist, only to find that the old man has passed on the position of sect leader to him before dying. His master has gone to the underworld to serve as a ghost official, while their founding patriarch ascended to the Upper Realm a thousand years ago and has been missing ever since. His own Daoist skills are barely at the beginner level, but fortunately, he has a Disciple-Accepting System. He fights monsters and levels up, takes on disciples and reaps rewards from them, eventually cultivating to immortality in the Age of Declining Dharma.
