She is the adopted daughter of the Grand Master, and she is also a killer. Because the Regent requested a marriage, the Grand Master had to marry a daughter.
Due to the hatred between the Grand Master and the Regent, he did not want to marry his own daughter to the Regent's Palace and suffer the consequences, so he asked her to marry into the Regent's Palace instead.
She thought that by leaving the Grand Master's Mansion, she would be free from the Grand Master's control. Unexpectedly, the poison in her body broke out and she was almost destroyed. The Regent saved her life many times, but she only wanted to complete the task and assassinate the Regent. In the end, she was determined to get rid of the Grand Master's Mansion and cooperated with the Regent. The two of them cooperated and came into contact with each other, and developed a mutual friendship.
One day she vomited blood and became poisonous. The regent said in a panic: "Don't panic, I will find the antidote."
Her poison made him even more panicked than he was, and she searched everywhere for the miracle doctor's antidote.
