Twelve Cities of the Imperial Capital: No One Survives

A classical fantasy where civilization has regressed, featuring a heroine with multiple sets of memories and a loyal, devoted hero with a mysterious past 1 What? Human civilization has regressed to the ancient era?! In some future year, they fled Earth and came to Hanxing. Luckily, Hanxing's environment was just like Earth's, but they soon realized their situation was disastrous from the start: Hanxing rotated upside down, with one half in perpetual daylight and the other in perpetual night. And it was gradually drifting away from its star, about to enter an eternal night. Even more despairing, technology could not be developed here, forcing human civilization to regress to the level of the Song dynasty… 2 Cang Xue was a young physician at Hanshan Academy until one day she lost her mind and killed several of her fellow disciples. Beaten within an inch of her life, she was thrown into the Longyuan prison and left for dead. Just as she gave up all hope, her blind guard Wanzhao crossed mountains to break her out. “Xue'er, whether or not you killed anyone, I'm taking you with me. I promised I'd protect you.” 3 Only after accidentally trespassing into a forbidden place did she discover that Hanshan Academy was far more than it seemed. The headmaster, the elders… even Wanzhao: every one of them was tied to Hanxing's eternal night. As the mysteries surrounding her were revealed one by one, Wanzhao grabbed her in a panic, his warm palm trembling slightly. “You promised you'd never leave me.” But Cang Xue's voice was as soft as falling snow. “A-Zhao, the truth is… I'm the eye of the eternal-night storm.” With civilization at the level of the Song dynasty, how can they save themselves from the apocalypse…?!
