The whole city is afraid of Shendu, because among the graves he sweeps, someone will die within seven days. Until he dug up the Dongshan Ancient Tomb, a bronze coffin engraved with golden dragons came out of the earth - there was no body in the coffin, only a piece of blood writing: 'You are Allah, whoever opens the coffin dies'. Zhou Jin showed up with a map of forbidden texts, Bai Ying used the corpse to get a glimpse of the past life, and Tietou Qi trembled and took out half of the map. When the evil wind haunted him again, Shen Ya finally understood: he was not a grave sweeper, but the key to the dragon's veins that had been buried for twenty years.
