"There are never born demons in this world, only human beings crushed by the law of heaven. The moment the lantern fell into the river, the fingertips of He Xingmian, the second daughter of the He family in Shuangwu City, were still holding the word "peace" that she had not yet written down. When she opened her eyes again, she was already in the world of cultivating immortals in the yellow storybook, and became the "most useless" master of the Xuanxu Taoist Sect - without any amazing magical skills, but with two apprentices destined to kill each other under her knees:
The sickly young boy Xu Yuze is the villain who will eventually become a demon in the novel, and his palm hides a blood mark that even heaven can quickly eliminate; while the extremely talented Mu Zhixu is the destined protagonist who is destined to kill the demon with a sword. At this time, they were still learning herbal medicine in her small bamboo-fenced courtyard, but they didn't know that in the future, their master would die and the master and his disciple would turn against each other in the Nine Heavens Tower.
