I Work as a Fake Eunuch in the Palace

Unemployed young man Li Dagen saved someone from drowning, but when he opened his eyes, he queued up to purify himself in ancient times. A fire allowed him to sneak into the palace with a waist card issued in advance. From then on, he dressed as a eunuch during the day and protected a beauty at night. He relied on modern thinking to fight for power, solve strange cases, support the empress, and rule the world. However, when power was overwhelming, he discovered that the person he was impersonating was originally a secret chess piece that could overthrow the entire dynasty.
