During the Lunar New Year, demons and demons are in chaos, and all life is in ruins. Han Qing, a seventeen-year-old orphan, looks innocent and harmless, and is often jokingly called the "innocent scholar". However, no one knows that the ancient treasure "The Roulette of All Realms" is hidden in his body, which can use the demon soul as fire to temper his body. When there was fraud in the military examination, loyal ministers were killed, and the border was in crisis, Han Qing had to repeatedly jump between pretending to be a pig and eating the tiger, and showing off his talents. In the court, he pretended to be innocent, making the powerful officials laugh at him as a "lamb to be slaughtered"; on the battlefield, he killed demons and demons with thunderous means, scaring his enemies to death. In the north, the demon army under the Demon Emperor is suppressing the territory. There are internal conflicts among the royal family, the dictatorship of relatives, and there are also legends about mysterious forces coveting the artifacts. Han Qing dealt with all parties, and every "unintentional" move made his opponents regret it; every "forced" outburst made the world look at him with admiration. How will he reach the top step by step in this era where demons are rampant and human nature is distorted, and reveal the truth behind the drastic changes in the world?
