Zhou Xingxing, a young man who loves adventure and extreme sports, and likes to read history books such as 24 Histories, accidentally got a metal token made of special material in Ailao Mountain. He was forced into a mysterious cave by a vine that made sounds, moved, and biting, and closed it. With the key to traveling through time, he traveled to the Southern Song Dynasty by chance and started a fierce battle of wits. He assisted Xiaozong and allowed him to slowly become a prince from a declining and outdated descendant of the clan, and finally became a great treasure, creating the rare "Qian-Chun rule" in the Southern Song Dynasty. (No harem, no routines, no cool writing, no system, no brainlessness, please be careful if you mind)
