The seventh son of the East Sea Dragon, Bi'an, encountered setbacks during his heavenly tribulation. His soul fell into the mortal world and possessed the body of Shen Zhao, the legitimate son of the Shen family who had been missing for ten years. His body suffered severe trauma from sorcery, leaving him with only a month of vitality. Awakening in a desolate tomb, he crossed paths with Lu Qichi, who had passed away carrying grievances. Returning to the perilous Shen family manor, he tore apart the hypocritical schemes of his stepmother and cousin. To survive, Bi'an successively solved bizarre and enigmatic cases. Prince Chen, Pei Jingheng, possessed heavy, auspicious blessings; closeness to him could nourish the divine soul. From mutual utilization to investigating cases hand in hand, the two dug up a conspiracy by the Yuan clan that had lain dormant for a century. With Bi'an's divine soul on the verge of shattering, Pei Jingheng protected him with his blessings, and the partners ultimately became soulmates through life and death.
