I'm a Proper Sword Cultivator, Yet My Strongest Technique Is Running Fast

No CP, no System, no rebirth: a triple-no product. Lin Yan is a princess, but her father and mother are murdered one after another, and she herself is turned into a human test subject for poisons. So what? She's immune to every poison. Watch her outlive the wicked old man, enter the cultivation world, savor every delicacy under heaven, and win the hearts of beauties everywhere. When in doubt, poison them first. When the situation is unclear, poison them first. When your cultivation is too weak, poison them first. Someone disrespects me? Poison them! Their hands turn into chicken claws! Someone steals my opportunity? Poison them! Their lungs start wheezing! Someone takes advantage of my misfortune? Poison them! Their eyes expand tenfold! What? You ask what I use my sword for? Fanning myself, of course! The protagonist kills, burns, and poisons. She's strong, cautious, and a total ham!
