My Sleep Problem Made Me a Dimensional Apex Predator

For three agonizing years, Zhuang Hong has been hunted. Cursed with the ability to traverse dimensions after absorbing a mysterious bone, he's become 'prey' to terrifying 'natural enemies' who feast on his unique energy. Sleep is a luxury he can't afford, lest he be ambushed and devoured. He’s a walking zombie, surviving only by consuming these very predators, growing stronger with every bite, turning him into a 'three-dimensional cancer cell' to a greater four-dimensional life form. But when his childhood friend is diagnosed with terminal lung cancer, Zhuang Hong realizes his monstrous power might be the only cure. Using his bizarre spatial abilities, he can literally extract tumors from within the body, a terrifying but effective 'surgical' method. Now, with his friend's life hanging in the balance and the cosmic hunters closing in, Zhuang Hong must brave the most dangerous dimensions, devour stronger foes, and embrace his monstrous reality. But will he find a cure, or merely become the ultimate, sleep-deprived apex predator—a tumor too big to ignore, even for a four-dimensional being?
