During the awakening of the Heavenly Book, there was an unusual movement of energy, detected by a powerful Demon Cultivator who attempted to subdue this Magical Treasure. Unable to tame it, he resorted to forcibly splitting the Book Spirit, inserting himself into the arrangements to gain control. For a while, it seemed successful, the Heavenly Book brought significant value in his hands, allowing him to rule a planet.
But starting from a certain year, the most powerful beings in the book began to awaken one by one, and the Demon Cultivator failed to notice this in time. He was severely tricked by the Emperor Ye in the book, leading to a complete loss of control. The re-engagement thirty years ago resulted in another blunder, and he has been hiding in his Cave Mansion recovering ever since.
Trying to tame a Magical Treasure at one's level is this difficult, with countless cultivators dying from backlash; he is neither the first nor the last.
