Gu Nanfeng became the guardian of the 'mysterious treasure' due to an accidental misplacement, and was involved in the dispute between the three realms. He teamed up with the alchemist Lin Manman, the silly warrior Shi Dashan, the mysterious warlock Su Miaoyin and the talkative mascot Pipi to form the "Laughter and Tears" expedition team. The crowd travels through three realms amid strange cases, dangers and comedies, from border villages to ancient ruins, fighting wits and courage against various forces. They pursue their dreams and uncover mysteries amidst hilarious daily life, dangerous crises, teammate friendship and their own growth. In the end, everyone worked together to break through the ultimate difficulty, not only protecting the balance of the three realms, but also regaining their true selves and precious bonds.
