Lu Shan, an ordinary office worker, is reborn as a ferocious tiger. Foreseeing his inevitable fate of being captured, he uses a simulator to turn the tables and foil the schemes of cultivators. After more than a hundred simulations and deductions, he narrowly escapes deadly encirclements, slays powerful enemies, saves three female leads, and obtains rare treasures and peerless cultivation techniques while forging alliances with worthy companions. Through careful planning, strategic alliances, and life-or-death battles, he breaks free from the established rules of the cultivation world and ultimately defeats his sworn nemesis in the final showdown.
