Ming Yingzong suddenly suffered from a strange illness. During the day, he was bright, but at night he was completely different. His dreams were full of memories of the old administration of the previous dynasty.
Qin Feng, the commander of the Jin Yiwei, was ordered to conduct a secret investigation and found that the emperor was poisoned by the "Night Wandering God", and all clues pointed to Wei Qian, the eunuch Bingbi, the eunuch of the ceremony.
Facing Qin Feng's questioning, Wei Qian frankly admitted: "I was responsible for the poison." But he had no ambition to usurp the throne, only compassion: "I spent twenty years just to plant a better Ming Dynasty in your Majesty's dream."
On one side are laws and imperial power, on the other are ideals and changes. When the means of saving the world becomes the crime of regicide, should Qin Feng's embroidered spring knife point to the truth, or a perhaps better future?
In this deep palace, the real poison is never in the bowl, but in the heart.
