The ruins of Kuji have eroded the world. Chen Mo, a Jianghu guest, carries the Taoist body of Nirvana and embarks on the road of salvation from suppressing cracks to stealing star maps, from transforming Jiuding to mastering fire. The four disciples burned their souls and turned into star trails, Emperor Yu's embers illuminated his way back; Phoenix Ancestor polluted and tore apart order, and his bones would desecrate the heritage of civilization. He lit a craftsman's fire in the forgotten cemetery, turned the cauldron into a boat in the sea of silence, reforged the order with the spirit of craftsmanship in "Kaogong Ji", and questioned the end of "nothing" - for the survival of the human race, should we surrender to disaster, or be crowned king in eternal calamity? The collision between oriental science fiction and traditional culture witnesses the mortal body holding fire to illuminate the eternal night.
