The girl Liu Yue (played by Wang Yijia) got a priceless Tibetan knife from her deceased grandfather. In order to find the real owner of the Tibetan knife, Liu Yue embarked on a journey. The news that the Tibetan knife reappeared in the world soon leaked out, and many cultural relics thieves, including Gong Jian (played by Yang Ziduo), heard the news. In order to get the Tibetan knife, Gong Jian concealed his true identity and secretly approached Liu Yue. The two traveled together, but they did not expect to encounter countless setbacks and accidents along the way. While overcoming these difficulties and obstacles together, Liu Yue's innocence and kindness were slowly changing Gong Jian, making Gong Jian give up the idea of robbing the Tibetan knife. Who knew that at this juncture, the Tibetan knife was stolen, and Gong Jian's original intention was also exposed. In anger and disappointment, Liu Yue broke up with Gong Jian.
