Jiang Che transmigrates into an abandoned Northeast tiger. With the help of a system, he trains relentlessly and grows stronger. By chance, he rescues a white tiger cub named Ji Ruxue who is being attacked by a pack of wolves, and takes on the role of her adoptive father, beginning his daily life of protecting and raising her. When spiritual energy returns to the world, Jiang Che bathes in a rain of blood and awakens the ancient Wraith Tiger bloodline, gaining the ability to control souls. He defeats an army of human financial tycoons and obtains the ancient exotic Nine Nether Purple Spirit Fruit. Alongside the human organization known as the Society for the Study of Extraordinary Artifacts, he overwhelmingly defeats the Four Beast Kings of the Thousand-Desolation Mountains, shocking the human world. He then ventures to the White Emperor Mountains to search for his runaway daughter, Ji Ruxue. There, he seizes the Nine Cauldrons from an alliance of powerful human warriors and achieves the ultimate evolution of his bloodline. After defeating the newly emerged Teng Snake, humans honor him as the Divine Beast Who Protects the Nation, and his path to becoming the Demon Emperor begins.
