Zhang Kuang, a young man from the modern era, travels through time and becomes the puppet emperor of the Great Yun Kingdom. The moment he opens his eyes, he witnesses the empress being whipped by disciples of the Black Mountain Sect, a cultivation sect, while his predecessor has been beaten to death. He awakens the People's Will System and learns the Human Emperor's cultivation technique, Nine Dragons Shatter the Heavens. Using only a mortal's body, he turns the tables and kills the sect disciples. He executes corrupt officials, opens granaries to distribute food, and abolishes oppressive policies, gradually winning the people's support and increasing his cultivation. First, he destroys the Black Mountain Sect, then battles the Profound Yin Pavilion. Joining forces with mortal kingdoms and the spirit beast realm, he eventually uses the perfected power of the Nine Dragons to defeat the Profound Heaven Sect's alliance against him, overthrowing 30,000 years of oppression by cultivation sects and establishing a new order where everyone is equal.
