Ye Jun is an obscure orphan, but he refuses to settle for an ordinary life. He is determined to join a sect, cultivate martial arts, and change his fate.
To scrape together money for the journey, Ye Jun ventures into the mountains to hunt. A venomous snake bites him, and just as his life hangs by a thread, disaster turns to fortune: the Primordial Dragon Venerable saves him and grants him an unparalleled legacy.
When alien races from the abyss invade, Ye Jun leads the human, demon, and devil races, along with other intelligent beings, in a desperate fight. At last, they defeat the invaders and preserve the civilization of all intelligent life.
