Chu Tian awakens in a chaotic world where the gritty underworld of classic Hong Kong triad films collides with the supernatural elements of popular anime. Reborn as a top enforcer for the Tung Sing triad, he quickly realizes survival depends on ruthlessness and unconventional methods. His most valuable asset is his new 'sister,' Feng Baobao, a deceptively cute girl with terrifying strength and a peculiar habit of burying people alive.

When tasked with collecting a debt from a stubborn gang speaker, Chu Tian does not resort to standard intimidation. Instead, he and Baobao drag the debtor to a dark forest, bury him up to his neck, and proceed to urinate on him to break his spirit. As Baobao cheerfully digs while quoting twisted Jianghu rules, Chu Tian navigates this dangerous fusion of criminal empires and superpowered beings.

With triad bosses like Chiang Tin-sang and anime characters roaming the same streets, Chu Tian must leverage his unique partnership to rise through the ranks, turning simple debt collection into a bloody spectacle that shakes the foundations of the underworld.
