The story begins in the late Tang Dynasty. During the Tianyou period, Huang Chao's rebel army captured Chang'an and blood flowed like a river. When the world was in chaos, a series of strange "lost soul cases" spread among the army. Soldiers disappeared mysteriously late at night, leaving only chrysanthemums with a strange fragrance behind. National Preceptor Yuan Tiangang calculated that this was a sign of great misfortune, and its origin pointed directly at the secret of Qin Shihuang that had been sealed for thousands of years.
