Become a Saint from Simulating Demonic Martial Arts

Zhou Lan traveled through the troubled times and became a demon-suppressing commander Xiaoqi. The world is in chaos and demons are rampant. Fortunately, there is [All Creatures Simulator], which can simulate the life of a demon, and you can also obtain cultivation, martial arts, treasures, and even use the life of a demon to practice your own martial arts. Simulating a snake demon will get [White Python Shaking Scales], simulating a white ape will get [White Ape Sword Technique]... Zhou Lan occasionally ponders, how much martial arts knowledge is enough? Until all things in the world were simulated and the fate of living beings increased, he lowered his eyes and looked up at the sky, "I will end the chaos in this world!"
