Lin Fan, an ordinary boy from a small town, embarked on the road to martial arts with the dream of changing his destiny in a world where martial arts were prosperous and power was respected. Along the way, he encountered repeated setbacks, used humor to resolve embarrassment and faced difficulties with persistence, and met like-minded partners Tang Wan'er, Niu Dali and Li Qingfeng. Everyone competes among the major forces, faces powerful enemies and the pressure of aristocratic families, and breaks through levels layer by layer. In the end, everyone uncovered the source of the world's turmoil. The former Martial Saint Mo Changqing degenerated into the Lord of Troubled Times. Lin Fan relies on his unique "Laughing Martial Arts" mentality to awaken sleeping justice, lead his partners to save the world, and complete his transformation from grassroots to legend.
