Fake Eunuch, I Am the Nine Thousand Year Old of Ming

Modern corporate slave Yang Fan transmigrates into a fake eunuch in the Ming Dynasty, dodges the identity verification crisis with wit, and becomes a servant to Empress Chen. He navigates the harem, secretly practices martial arts manuals to advance rapidly, and rises from a lowly eunuch to a powerful figure. During this journey, he battles Grand Eunuch Li, counters the Empress's schemes, breaks the 'Nine Sons Evil Dragon Plot', and ultimately quells the rebellion during the sacrificial ceremony.
