The Record of Killing Immortals and Killing Demons: Overturning the Nine Heavens with One Thought

Chen Xiang thought he was just an Internet-addicted boy addicted to fairy novels, until he held the demon-killing order left by his master in a pool of blood. On the evening when the Tianji Sect was destroyed, four hundred of his fellow disciples died tragically, and he was the only one who survived. The black-clothed demon cultivator told him a shocking secret: the seal of the Nine Heavens was loosened, and the ancient monster was about to return to the world. And the Demon-Slaying Order in his hand is the only hope to prevent the catastrophe. But the next second, he woke up in a bed in a mental hospital. The beautiful psychiatrist Liu Yifei told him: Those are all hallucinations, and you are just a mental patient. Tianjimen, Xiuxian, and seals all do not exist. There is no magic in the real world, only medication. But why is the Demon-Slaying Order still under the pillow? Why does Liu Yifei sometimes show eyes that are profound beyond her age? Why did the director of the mental hospital know the secret under his pillow? Which world is real? When Chen Xiang discovered that Liu Yifei was actually his junior sister in his previous life, when he realized that the mental hospital might be a trap of the devil, when he had to make a choice between "save the world" and "self-protection"—— One thought becomes a fairy, one thought becomes a devil. Every decision will overturn the order of Jiuzhongtian. Every killing tests his true nature. When the boundaries between good and evil are increasingly blurred, when it is difficult to distinguish between reality and illusion, who should he believe? This is a story about choice. When the truth of the world is peeled back layer by layer, and when the gears of fate begin to turn, Chen Xiang will discover that the most terrifying enemy is not the external monsters, but the inner demons.
