Leisurely Daily Life After Being Parasitized by a Demon

[Fairy world novel (non-immortal cultivator) + indigenous female protagonist, beautiful, strong and miserable, no time-travel and rebirth system, 1v1 + male protagonist with low sense of presence] The sun and moon are co-lords of the Nine Heavens, and the affairs of the three realms are jointly controlled by the Sun Emperor and the Moon Lord. Since the previous Moon Lord disappeared and his life and death were unknown, Heaven has never chosen a new Moon Lord. The Moon Palace has been without an owner for many years. The walls are in ruins and there is no light anymore. The tides in the world are chaotic and the stars and moon are out of order—— During the Waking of Insects, it rained heavily. Yunsheng fell to the cliff of death, and when he was dying, he heard the devil's whisper: "Want to live?" "Think." When he opened his eyes again, corpses were everywhere and blood was flowing, but it was a scene of purgatory. When Yun Sheng woke up from a dream, it was not a human being or a god who saved her, but the devil! On the line between life and death, no one gave her a choice. If she was given another chance, she might not choose life. From then on, he was possessed by evil spirits and lived half alive and half dead. She is like a creature that casts a glance into the abyss, and will one day be swallowed by the abyss. Yunsheng: Mountains, birds, insects, and fish are all free. Then so am I—— What's the point of living a life without freedom and joy?
