She is Song Yiyi, the concubine of the Prime Minister's Palace and the Grand Protector's Palace of her mother's family, who is loved by thousands of people. She is a literary and martial arts expert, a poisoner and a doctor. With the imperial edict, the Prime Minister's Palace and the Duke Protector's Palace are about to be raided for their rebellion. Since the Dog Emperor is so stupid, I, Song Yiyi, will let someone else sit on the throne.
He is the emperor's young uncle. He went to the battlefield at the age of eight, made great achievements in battle at the age of ten, and became a peerless master at the age of twelve. He is the 'bloodthirsty Yama' in the eyes of his enemies. But when he was at the peak of his life, he was poisoned, and all the famous doctors could not find out the cause. Every moonlit night, he would feel the pain of heart erosion. He found out that his poison was related to the emperor, but there was no evidence. He wanted to find her to try to detoxify with the last hope, but he saw the little girl's intelligence, tenacity, and how to deal with the enemy. His ruthlessness and kindness towards his relatives made him completely fall. His power and financial resources spread across the entire continent, and he was the most invincible backing of the little girl on the road to revenge. However, he and the little girl both had a system. Who was the super-controller behind the two systems, one good and one evil? How should two people with opposing systems hidden in their bodies face this dilemma together?
