The story originated from the discovery of the Sutra Cave in Dunhuang in 1900. A large number of sutras were lost overseas. One of the golden books, the Mahanirvana Sutra, revealed the secret of the Earth's axis, triggering a secret operation by the Nazis to enter Tibet to detect the Earth's axis. During this period, the German army encountered supernatural forces and was almost annihilated. Germany was defeated and the sutras disappeared. In 2016, the book reappeared, triggering a battle between good and evil between the protagonist and Japanese spies.
