I Cultivate the Great Dao in Another World

In the beginning of time, who first passed down the Dao?

Li Duofu, a Yin-Yang master, finds his soul transported to an ancient world in another realm. A meteor falls from the sky, spiritual energy awakens, and the world descends into chaos as demons and monsters run rampant. He takes up martial arts and cultivation, exorcises demons, subdues ghosts, brings peace to the realm, establishes a lineage, and accumulates merit.
