Li Chen, a modern social animal, accidentally traveled through time and fell into the purification room of the palace at the end of the Great Yan Dynasty. Fortunately, he kept his manhood and became a "fake eunuch" lurking in the palace.
On the night of the palace coup, he took advantage of the chaos and escaped from the imperial city, but accidentally entered the bandits' den, Heifeng Village, and relied on modern wisdom to resolve the crisis. He lived in Liangzhou City, where he helped officials eliminate banditry by mistake, but he repeatedly fell into desperate situations because of his identity as a "fake eunuch".
In troubled times, he holds modern strategies in his left hand and survival wisdom in his right hand. From the palace to the rivers and lakes, from bandits to the court, he travels among all forces with a special identity. He not only has to hide his secrets from being exposed, but also has to struggle to survive in the whirlpool of imperial power and division of heroes, and even wait for opportunities.
