The Strongest Body Customization System Novel

Ian, an ordinary man, is abruptly transported to a dangerous world dominated by vampires, werewolves, and demons. Transmigrated into the body of a lesser vampire, he must navigate a harsh new reality where survival is uncertain. Everything changes when Ian discovers The Strongest Body Customization System—a remarkable ability allowing him to modify his body by consuming biomass. This power becomes his lifeline, enabling him to craft bone claws and other physical enhancements to combat supernatural threats. As Ian gains strength and learns about the Curtained Imperium and vampire hierarchies, he realizes that mere survival requires more than combat prowess. He must ascend the ranks and fully master his system's potential to thrive in this brutal world. The system's possibilities are limitless: growing angel wings to achieve flight, expanding his body to colossal proportions exceeding Godzilla's size, or instantly manifesting bone claws and kagune as weapons. Through strategic body customization, Ian transforms himself from a helpless newcomer into a formidable force capable of reshaping his destiny.
