On the verge of death, Tang Xuan Zong misses the concubine he once loved. To ease his pain, he hopes to find Painter Wu Dao Zi to paint a portrait of the concubine. Young painter Tang An Zhou embarked on a journey to find Wu Dao Zi and came all the way to Qingyang Town, where he met an old beggar.
Various signs indicate that the old beggar actually concealed his life experience, and his true identity should be Wu Dao Zi who escaped. In order to lead the snake out of the cave, Tang An Zhou set up a lot of tricks, but he was always played by the clever old beggar and the innkeeper Hong Jiang, and his face was lost. In the end, Tang An Zhou grasped the handle of Hong Jiang’s life experience, and in desperation, the old beggar had to lead Tang An Zhou to a grave and told Tang An Zhou that Wu Dao Zi was buried in the grave.
