In a world of high-level martial arts where everyone practices martial arts and the strong are respected, the idle apprentice Li Xiaowu unexpectedly finds a romantic connection and suddenly rises from a small figure with abandoned martial arts in the midst of "unexpected errors" and farce. He forms an alliance with the adventurous famous girl Zhao Yuluo and the master of bickering Chen Shi, and works together to resolve the feuds between Jianghu sects, power disputes, and foreign invasions - the comedy escalates along the way, and unexpectedly becomes the hope of the world's martial arts. In the undercurrent of power and the torrent of bloody battles, they despised power with "laughter" and resolved seriousness with "noisy", creating a joyful life legend: no matter whether it is a chasm in heaven or hell, life is short, they must laugh proudly and be martial in the world!
