The former Prime Minister was sentenced to death for his heinous crimes, but Lu Yuan's soul happened to time-travel in at this time, and accidentally became this unlucky character. Facing the contempt and rejection of the people around him, Lu Yuan, who had just integrated into this new world, felt great pressure and dissatisfaction.

However, he still gritted his teeth and persisted, using his wisdom and courage to overcome these difficulties. With his efforts, society gradually improved and people's lives became richer and happier. However, at this moment, the dark forces in the court began to move around. They were afraid that Lu Yuan's reforms would threaten their status and interests, so they designed to frame him and try to push him down. Lu Yuan is facing unprecedented difficulties and challenges. He needs to find a way out, and at the same time, he needs to protect his family and friends. In the process, Lu Yuan gradually learned about the world he lived in and the people and things hidden behind history.
