There are two famous daughters in the General's Mansion, the eldest daughter is Su Jin, and the second daughter is Su Hua. One is the soil on the ground, and the other is the clouds in the sky. Su Jin is the unpopular young lady in the General's Mansion. She is cowardly and incompetent and allows others to bully her. Everyone knows that whoever marries the eldest lady of the General's Mansion will be unlucky for sixteen lifetimes. Whoever marries the second young lady is a blessing that has been cultivated in several lifetimes, and the smoke is rising from the ancestral graves. Who would have thought that later on, that cowardly young lady would transform into a stunning beauty, a master of medicine and poisoning, and a master of golden needles! And he is the regent who has all the power in the world and monopolizes the direction of the government. The world thinks that he is cold and heartless, and his methods are vicious. In fact, he has never killed an innocent person. Once they traveled through time, the two met, and they were granted a marriage by decree, and they battled wits and courage. That aloof man was only interested in her and would go to hell for her. He dotes on her, loves her, protects her, loves her, and is afraid of losing her.
