In the twenty-first year of the Republic of China (1932), warlords were fighting, foreigners were proselytizing, sneakiness was rampant, and witchcraft was everywhere. On the bank of the Haihe River in Jinmen City, Chen Jiu, a 20-year-old corpse stitcher, whose father died early, left him half a coffin shop, a rusty needle, and half a fragment of the "Embroidered Bone Sutra". He didn't know anything about cultivating immortals, had no adventure, no system, and no grandfather. He just understood the veins of the human body, understood the texture of life and death in the process of sewing the dead bodies again and again, and found out from the corpse's resentment a path that no one else had ever walked before - using needles as swords, threads as veins, and corpses as teachers, he started as a corpse stitcher in the mortal world, and sewed all the way to the Immortal Immortal.
