Yang Fan, a modern social animal, traveled through time and became a young eunuch in the palace. He lost his family heirloom at the beginning and was treated as a coolie by the ruthless Eunuch Li. Unexpectedly, while waiting for Concubine Chen to take a bath, he discovered that he was not a real eunuch, and that there was hope hidden in the desperate situation. The deep palace is like a cannibalistic purgatory, and human life is as light as grass. With the help of "Barbarian Bull Body Building Technique" and "Heaven and Man Treasures Picture" and other exercises, Yang Fan has gone through palace battles, workplace assassinations, and Tiger Mountain trials, and has counterattacked all the way from the bottom eunuch.
