Xiao Shi Yi Lang was a wuxia novel by Gu Long. It told the story of the emotional entanglement between Xiao Shi Yi Lang and Shen Bi Jun. At the end of the novel, Xiao Shilang was mistaken for Shen Bijun's murderer and was put in prison. In prison, Xiao the Thirteenth met a mysterious old man who told him that his real identity was Shen Bijun's son, and Shen Bijun was mistaken for Xiao the Thirteenth's murderer because he was injured. The old man also told Xiao the Thirteenth that he needed to wait in prison for a while because Shen Bijun needed to treat his wounds. In the prison, Xiao Shilang met many interesting characters, including the villains and other prisoners. He also thought about the relationship between his identity and Shen Bijun and finally understood that his true mission was to protect Shen Bijun, not to kill her. Gu Long expressed some thoughts at the end of the novel. He told Xiao the Thirteenth that life was like a journey. Sometimes we would lose ourselves, but as long as we could find our true self, we could find the way home. At the same time, he also hoped that Xiao Shilang could wait for Shen Bijun to protect her in prison until she recovered. The ending of Xiao the Thirteenth conveyed the true meaning and philosophy of life.
