The World Is in Turmoil: This Eunuch Is in Charge of Black and White

Jiang Han, a modern emergency physician and history enthusiast, was rescuing a dying old man who claimed to be a "Ming Dynasty survivor" when the old man thrust a dragon-patterned blood jade into his hand. That night there was a thunderstorm, the ancient jade glowed, and Jiang Han traveled to the Zhou Dynasty. On the night of time travel, because of her handsome appearance and unique temperament, she was temporarily transferred by the eunuch in charge to serve Xiao Nichang, a young empress dowager (23 years old) who suffered from insomnia and irritability due to "a chronic headache". Seeing his unique technique (modern massage techniques), the Queen Mother kept him on guard overnight. The Queen Mother drank a soothing soup that had been secretly added with medicine, and Jiang Han had no choice but to save the Queen Mother's life... One night later, the Queen Mother woke up and found something strange, and Jiang Han's life was hanging by a thread.
