Xavier Quinn, the Mystic Successor, leaves his mountain seclusion to enter the mortal world. Bearing the blood feud of his clan's massacre, he unexpectedly crosses paths with Lila Bancroft, CEO of the Bai Group, in Jiangnan. One defeats enemies with his fists, the other controls the situation with her wisdom. The two go from mutual testing to fighting side by side, working together to confront the thousand-year-old shadow organization the Nether Syndicate. The reunion with his long-lost sister separated for ten years, the loyal waiting of a reclusive old servant, the awakening resonance of closest blood ties — as all truths come to light, Xavier Quinn uses his iron fists to protect everyone around him, and finally gets justice for the 137 deceased members of his clan. His fighting spirit never fades, and justice will always prevail.
