Su Wan, who was reborn as the lowest servant of the Qingyun Sect, held the "Tian Yuan Zi" left behind by his mother and fell back to the mortal world from the fairyland three hundred years later with his symbiotic pet Tanyue. This time, he is no longer an "abandoned son" who is left to be slaughtered, but as a "chess player" to restart the "Tian Yuan Chess Game" set up by his mother - the numerology line on his fingertips can change the fate of mortals, and the spiritual pet on his sleeve can swallow up the murderous intentions of heaven. Under the seemingly cynical appearance, there is a plan more vast than the heavens.
