Fumigating the Dragon Throne

Cen Bai, a cynical modern exterminator, wakes up in the sickly body of a disgraced noble heir exiled to the Qiling Miasma Basin - an absolute death sentence in the ancient Yanfeng Empire. His treacherous rivals expect him to be devoured by the mythical Venom-Horned Centipedes that plague the wetlands. Instead, Cen Bai recognizes the monsters for what they truly are: oversized arthropods highly vulnerable to basic chemical disruption. Using rudimentary ancient alchemy to synthesize modern pesticides, pheromone baits, and fumigation tents, he rapidly neutralizes the deadly swamp and transforms it into a highly profitable, self-sustaining utopia. But his sudden economic rise draws the greedy eyes of the capital's elites. When the terrifying imperial inquisitor Luo Wanzhou is dispatched to execute him for practicing 'dark magic,' Cen Bai realizes the true infestation lies within the royal court itself. Armed with homemade bug-bombs, toxic gas, and an intricate understanding of parasite behavior, he sets out to systematically exterminate the empire's corrupt bureaucracy. Can a humble rat-catcher outsmart the apex predators of high society, or will he be crushed under the emperor's heel?
