The Powerful Minister Ascended to Immortality: the First Fake Eunuch in Daqian

I am a fake eunuch and a chess player who controls the entire dynasty! In the eyes of the world, I am the most humble lackey around the emperor. But no one knows that I am the deepest secret of the Daqian Dynasty - a fake eunuch with power over life and death. [The Heavenly Emperor System] is in hand, and the secrets of the civil and military affairs of the entire dynasty are invisible to me. I know where the general's illegitimate son is; I also know where the prime minister's treasonous letter is! Does the feudal lord want to rebel? I'll cut off his food and fodder first! Does the imperial concubine have a different intention? Her secret lover will be found dead in the streets tomorrow! Everyone thinks they are chess players, but they don't know that they are all my chess pieces. Starting from the cold palace, I will use this eunuch's skin to create an immortal royal robe for myself!
