In 2059 AD, the neon lights of New Luoyang flooded the old palace walls. The imperial power is controlled by the "Aisin Gioro Group", and the concubines in the harem are actually data witches, competing in the virtual Forbidden City for the authority to access the neural interface leading to eternal life. Zhen Huan, the only "primitive" who has not been implanted with a biochip, suffered a data lotus collapse on draft day and was driven into the most peripheral server node.
When she discovers that the emperor's upload plan is actually a devouring ritual of the ancient existence "Nine Heavens", when Concubine Hua reveals the mark of the old god under her semi-mechanical body, and when An Lingrong's singing begins to distort dimensions - Zhen Huan must use the mechanical key left behind by her father to fight the ultimate war about human consciousness in the deep sea of data and Cthulhu-style fear.
This is a palace fight without gunpowder, the loser will be formatted, and the winner will become a container for inhuman existence. The only weapon Zhen Huan holds is something that the old gods can never understand: human nature.
