Reborn as a Eunuch in the Cold Palace: From the Start, I Sign In for Yin-Yang Cultivation

Overworked office drone Cao Kun transmigrates into a fake eunuch in the Cold Palace. From the start, he catches Consort Shu bathing, and finds himself surrounded by corrupt officials across the court: a hellish start in an era of eunuch domination!

Inside the palace, the likes of Wei Zhongxian and Zhao Gao control the inner court. Beyond its walls, An Lushan and Huang Chao lie in wait, while the harem is filled with ruthless figures like Zhao Ji, Empress Lu, and Wu Zetian.

Just as Cao Kun thinks he's done for and prepares to have one last fling before killing himself, he unexpectedly activates a god-tier sign-in System. His starting reward is the Yin-Yang Union Art!

From then on, Cao Kun uses his position to navigate the harem and the imperial court, wooing beauties, battling corrupt officials, and seizing power!

From a lowly eunuch servant who anyone could bully, he rises step by step to become a hero of a chaotic age!!!
