Lin Wanxing accidentally entered a fantasy novel and became the stand-in for the villain witch. Not only did he have to imitate the witch's words and deeds, but he also had to face the tragic ending of the original owner who was destined to be killed by the paladin Adrian. In order to save her life, she ostensibly obeyed the villain's instructions and secretly avoided the plot points, but her flaws were revealed in repeated confrontations with Adrian - she would secretly save injured animals, and would subconsciously protect civilians when danger came. These actions that were completely different from a "witch" made Adrian, who wanted to monitor her, gradually shaken. When the villain's true identity was exposed and Lin Wanxing was in dire straits, Adrian actually drew his sword to protect her. The eyes of the former cold paladin were full of determination: "You are never anyone's substitute, you are the person I want to protect." In the end, Lin Wanxing not only changed the outcome of her death, but also received the affectionate protection of her own knight.
