White Snake: I Am Xu Xian, the Immortal of the Sword Immortal!

It was raining slightly in the West Lake, and when Xu Xian picked up the fallen hairpin, he realized that in this life, he had accidentally become a reckless hero. Is there any way to save him? After awakening the system of healing and adding points, I, Xu Xian, am no longer a weak scholar, but a swordsman! From "Elementary Herbal Identification" to "Refining the Body and Transforming into an Immortal" From "The Art of Elementary Talisman" to "The Master of Talisman" … Treating diseases and saving people cannot save stupid people, who said that? Isn't treating a demon a cure for a disease? I see this demon killing people, setting fires, and going crazy, so curing this miserable demon creature is not treating a disease? Studying medicine can't save stupid people and monsters? You might as well ask about the three-foot long sword in my hand! Xu Xian: "If I say you are sick, you are sick. If you don't believe it, we can try it." Walking between heaven and earth, I have the final say whether you are sick or not!
