Chen Xing, a 996 office drone, dies suddenly and reincarnates as a disposable spirit turtle in Qingyun Sect's Ten-Thousand-Beast Abyss—used solely for disciples' sparring practice. On the brink of death, he activates the 'Gluttonous Xuanwu System': every blow he takes converts into cultivation power and replicates enemy skills. He flips the script—taunting everyone openly, evolving publicly mid-fight—and draws the obsessive attention of the deranged Elder Sun and the kind-hearted圣女 Lin Qingxue.
