Hundred-year-old rabbit demons "An Qi" and "Bei Qian" fell in love. Later, "Bei Qian" was locked in a moonlight box by the thousand-year-old turtle "Yi Pei" and was thrown into the earth. After turning back into human form, "An Qi" could only secretly take away two elixirs from "Yi Pei". Later, "Yi Pei" captured her and made a request. If the mission of catching and killing "Bei Qian" failed, she would never be human again and become a star in the universe. Later, "An Qi" fell in love and killed each other, and "Bei Qian" fell in love with "Chen Nian". Finally, "An Qi" and "Yi Pei" were defeated by "Bei Qian" and became stars in the universe. "Bei Qian" became a real human being and lived an ordinary life of love.
