On the surface, Feng is a traitor, and he will do whatever it takes to achieve his goal, even protecting the traitor Lu. But in fact, he did it to convince Lu that he and he were the same person. Only by gaining trust can he bring down the other party and clear his mother's name.
His mother is the emperor's concubine, so his maternal line is Ming. The Ming family made great contributions to the court, but in the later period of the emperor, they doubted the Ming family for no reason and killed all the Ming family members on trumped-up charges. These things have been deeply remembered by Feng. In order to wash away the grievances of the Ming family, he used various means to enter the court and became very close to Lu who framed the Ming family.
At first, Dongyue thought Feng was a big traitor, so there were many misunderstandings between them, because she lost Feng in her previous two lives. It was not until the third world that she knew Feng's identity and fell in love with each other. After two people fall in love. Together, they defeated and eliminated the Ming family. When everything came out, the emperor regretted it very much and confessed to Feng what he had done wrong. Finally, Dong Yue and Feng lived in seclusion in the mountains and lived the life they wanted.
