Uncle Wan entered the palace at a very young age. He was ugly and not favored. No noble master was willing to want him, so he was thrown into the Cold Palace.
In the Cold Palace lived Emperor Jingyang's deposed Empress and the two princes that the deposed Empress gave birth to for Emperor Jingyang. The younger prince was the same age as him. At that time, he didn't know anything. The eunuchs asked him to "take good care" of the prince, so he really served the prince with all his heart. The eunuchs in the Cold Palace died one after another. He was the only one who accompanied the two princes until they became adults.
One day, the Eldest Prince found him and said to him, "Wan Guancai, I want to leave the Cold Palace. Are you willing to help me?"
He nodded.
The Eldest Prince handed him a bag of poison. "Put it in Sixth Brother's food."
