Not only did he receive cold looks on his job search, but even his own father shook his head and sighed. As for the blind date market, it was like a roller coaster, all the way down until it hit the bottom. However, fate seemed to think that it was not exciting enough. On that ordinary night, because he could not breathe, Li Hao dramatically traveled to ancient times and transformed into a six-year-old boy, Li Hao, and became the county magistrate.
Li Hao, who had just arrived, found himself in a strange dynasty, but he did not panic.
