Lingli, the ninth princess of Qingqiu, is the nine-tailed fox cub held in the palm of the fox emperor's hand. The eighth sister is wrapped around her knees. She doesn't know how to feel sad, but she only loves to entangle the Cangwu priest who holds the power in the demon world - Ye Xuancang. He was two thousand years older than her, covered in silver robes, and as cold as the eternal ice, but she was always disturbed by her little tricks: she dared to steal the hosta from his hair, she dared to stuff a candied haws in his mouth while he was chanting, she dared to stand on tiptoe and brand a fox mark on his neck, and she turned around and called him "Uncle Ye". Hanyuan became Ye Xuancang's usual place, and those sweet dreams about Lingli always made his fingertips turn white. He thought it was an occasional ripple of time, but when she was promoted to the position of a saint, he was shocked to realize that possessiveness had already become crazy. The truth about her mother's death at the hands of the dragon clan shattered the peace. The second sister abdicated, and Lingli was forced to shoulder the responsibility of the saint. She and Ye Xuancang went from tit-for-tat to embrace through calamity. In the warmth of the red candle tent, he bit her earlobe and said, "I can't run away." But in an instant, they turned against each other due to the catastrophe of the Fox clan. In order to protect her tribe, Lingli stepped onto the fire altar. In the blazing flames, she looked at him with a smile: "Ye Xuancang, forget me." However, after her soul dispersed, he used his half-life cultivation as a guide to crush the three realms to find her remaining soul. When they reunited, she became a rabbit demon who had no idea of her past. He locked her in Cangwu Hall and allowed her to poison her with a sword, only muttering "stay". On the night when her memory came back to life, the warm spring night was no match for the blood feud, and she left again. This time, Ye Xuancang lost all pretense and went crazy to pursue his wife, but he didn't know that his fate had already been determined - when the final disaster comes, one of them will have to go to that heart-burning fire again for the sake of all sentient beings.
