Wei Fei: Starting from a Brain Tumor

There is a door in the world, hidden in the gap between light and darkness. Those who are not destined cannot see it, and those who are not special cannot knock. Those chosen by the Fei Fei inherit the power of the Fei Fei and are also bound by the Fei Fei - the power is born in the cunning corner, and the price is hidden in the bones and blood. An ordinary office worker sinks his boat, and accidentally crashes into a strange place. His consciousness is ground to ashes between death and reorganization. When he opens his eyes again, he has become a cold-blooded stranger parasitic on the brain tumor of a young man. A second-grade top-notch gun-wielding girl, a fierce swordsman in the mountains, and a swift-moving swordsman. He clutches the Guipin seal core. His body is just a malignant brain tumor, but he is determined to live as long as the world and compete with the sun and the moon. He is not willing to die completely, he wants to live, no matter what! With infinite hatred, he would completely smash the trick door that brought him infinite death. As his name suggests, he is desperate and desperate. [Fantasy time travel + dark writing style]
