Reborn into the Great Wu Dynasty, Li Changsheng becomes a (fake) eunuch in the imperial harem. He aspires to be like Lao Ai, but instead becomes the strongest eunuch on Earth.

In terms of political achievements, he established schools, implemented reforms, rectified official corruption, swept across the land, and brought peace to the world for generations to come!

He fought against powerful ministers, but in the end, he inexplicably became the most powerful minister and the most treacherous traitor!

When it comes to economic development, he transformed the once precarious Dawu into a prosperous and powerful nation, even surpassing Tao Zhugong!

In terms of talent, if all the talent in the world were equal to one bushel, he alone possessed twelve bushels, and the rest of the world would owe him two bushels!

A man of many talents, he wielded power over the world when awake, and rested his head on the lap of beauties when drunk. Princesses, imperial concubines, noble ladies, and chivalrous women all loved and admired him.

...

The stunningly beautiful empress later looked back and thought: "You dog of a man, I asked you to manage the harem, how could you have dug it all up?"
