A Golden Core in Ruins: After I Died, My Disciples Turned Dark

System transmigration + brainless indulgence + yandere + master and disciple + one heroine + raising an Empress Gu Wanzhou transmigrates to the world of immortal cultivation, but the System, short on energy, dumps him into a defective Core Formation body with only sixty years left to live. To complete the System’s missions and earn a chance to be reborn in an immortal body, he saves Xiao Qingluan, a girl betrayed by her own family, in a chaotic age where resources are desperately scarce. The master and disciple rampage through the cultivation world like rabid dogs, plundering resources: selling divine talismans, scavenging corpses, breaking into forbidden zones, and killing rogue cultivators. Through bloodshed, they propel Xiao Qingluan to the throne. At the moment when she is most vulnerable after becoming Empress, Gu Wanzhou burns up the last of his soul to take a fatal blow for her, dying with a smile. Ten years later, Gu Wanzhou is reborn with his memories intact as the son of a wealthy family. Just as he prepares to flee an arranged marriage and seek immortality, he is dragged into the bridal chamber. There he discovers that the bride, who should have been marrying a landlord’s son, is none other than his disciple, the Immortal Emperor who rules across the Three Realms and now gazes at him with obsessive, darkened eyes.
