The story follows Prince Tang, who was born amid chaos as his homeland fell apart. Raised in secret by his wet nurse in a border town, she instilled in him the hope that he would one day reclaim their kingdom. Known as Xizitang, he carried the weight of his family and nation's fate. At age eight, his wet nurse sent him to Chuiyun Mountain to train.
After ten years of intense cultivation, Xizitang broke through to the realm of immortality, wielding his ancestral divine hammer of martial arts. Bold as a young calf unafraid of tigers, he swore to defeat the Eight Immortals and overthrow the Liberated Four of Penglai, aiming to bring peace to the continent. Though the land is filled with immortal cultivators, Xizitang is still a beginner. An assessment by the town's immortal list labeled him a low-grade mortal immortal. In the current Datang, even food delivery jobs require one to be a mortal immortal. So, after gathering countless advantages over ten years, how will Xizitang, newly entering the arena, stir up a bloody storm?
