Xiao Qing, whose full name is Li Xiaoqing, was once the mistress of Li Tie, the former gang leader in Capital City. In reality, she was an undercover agent sent by the Qin family to monitor Li Tie. That day, Ye Tianchen didn't kill Xiao Qing because he sensed no murderous intent from her. Moreover, Li Xiaoqing is an Illusion Technique Superpower User, a type of Superpower User that was rare in the apocalypse, and even more so in this life. That's why Ye Tianchen let Xiao Qing go.
Unexpectedly, this time, Wuxue called upon masters from the Ancient Martial Sects and the Superpower World to form the Thirteen Heavenly Kings, and Li Xiaoqing had joined as well, becoming the only Female Heavenly King among them. This truly surprised Ye Tianchen. He and Xiao Qing were old acquaintances after all, but he hadn't expected that now Xiao Qing would become his subordinate and join the Thirteen Heavenly Kings.
"Don't worry, I won't be a drag on you all!" Li Xiaoqing said with a charming smile.
