In the Jiuzhou Continent, the spiritual energy is revived but the way of heaven is incomplete, making it difficult for mortals to reach the path of immortality. The shepherd boy Liu Changan was pierced by the Nine Heavens Divine Thunder in Qingniuling and was immortal. He awakened the chaotic thunder body that had been lost for thousands of years - it could swallow the thunder of the heavens, evolve thousands of thunder methods, and trace back to the origin of thunder disasters. He was originally the direct son of the god who was demoted to the mortal world from the "Thunder Ruins Divine Court" in the upper realm. His body had his memory sealed in order to guard the ancient ferocious beast "Zhu Yin" sleeping deep in the Kyushu earth veins. As his cultivation improves, Liu Changan gradually uncovers the mystery of his life experience, and discovers that the thunder techniques practiced by Kyushu monks are all derived from the reverberation of his bloodline; and the countdown to Zhu Yin's breaking of the seal has been started, and the world will fall into a catastrophe of thunder and fire. He must recast the orthodox thunder path, gather the luck of the nine states, and refine the divine thunder of chaos. Before the final seal collapses, he must use his body as a gate to suppress evil on behalf of the sky.
