Why Did He Become a Wanted Criminal When He Woke Up?

Cheng Zhihong lost his memory and traveled thousands of miles to search for his father, but was told that his father had assassinated the emperor and had been executed. Not only that, the world also said that General Cheng only had a son but no daughter. She looked at the young general with the same name as her on the wanted poster with full of doubts. He was indeed very similar to her father. He had decided to face this monstrous conspiracy alone, but unexpectedly, the Third Highness Song Yaoguang showed no fear and followed him for nothing. The two work together to break the situation, only to discover that someone in the Cheng Jiajun's old department at the frontier is dying mysteriously... Just when everything was about to be solved smoothly, Cheng Zhihong was trapped within the high walls of the imperial city. The geese at the frontier fortress are used to seeing loess and windy sand, drinking strong wine, and riding horses. How can they face the open and secret arrows of the concubines in the palace wall? Who will break the door? Who will uncover the conspiracy? Who will bring down those in high positions? The heroine who seems cold and distant but actually gives you her life vs. The male protagonist who seems to be carefree but is actually far-sighted ps: The heroine's mother is a time-travelling woman, so there will be some strange settings in the previous article, which are not bugs. But my mother has passed away at the beginning of the chapter, and the entire chapter only exists briefly in memories, so there is no time-travel element involved. Intention: Between good and evil thoughts
