Retired for ten years, returning in a single day, holding the skies with one hand, who can fight a battle with me—the legendary Sovereign Yama Qin Zongheng of the dark world, incognito and dormant as a prison guard in Jiuyou Prison, entrusted by the benefactor Elder Shen, goes down the mountain to protect Shen Mange, the president of the Shen Group. Faced with the coercion of the Dragon-Rising Association, the interception and killing by overseas mercenaries, and the betrayal of corporate insiders, Qin Zongheng sweeps away all enemies with absolute strength, beating gang hall masters with his fists, kicking martial arts experts with his feet, and casually suppressing S-rank felons.
