Ye Chen was once the surrogate son-in-law of the Shen family and donated a kidney to his wife Shen Aoxue. However, the Shen family colluded with the imperial family to steal the second kidney and push him off a cliff. When he was about to die, the hidden Killing Emperor saved him and gave him Kirin kidney, Kirin blood, the inheritance of the God of Killing and peerless medical skills. Three years later, Ye Chen returned for revenge and rescued his old acquaintance Ning Xin who was blinded due to the investigation of the truth. He exposed the kidney-stealing conspiracy in public at Shen Aoxue's wedding banquet, and successively liquidated the Shen family, Xu family and Tianqing God of War disciples. He found the elixir to cure Ning's eyes, uncovered the imperial family's peripheral minions Di Fengwu, and found out the truth behind the transfer of kidneys to the imperial capital. The Shen family and the Xu family were all destroyed, and the villains were each punished.
