The Illusory Demon Master

This is the forbidden land known as the "Ruined Capital," where even a celestial immortal would meet their end. Within the Ruined Capital lies a village called "Peach Blossom Spring." It is home to a group of peerless great demons who eat humans. They often fight one another, killing many top experts who come seeking their destined opportunities. One day, a transmigrated blind man named Cao Sanqi arrived. The man-eating monsters respectfully addressed him as "Sir." In the blind man's eyes, Peach Blossom Spring was inhabited by a group of kind, simple, diligent, hardworking, loving, and helpless commoners. Being a teacher in Peach Blossom Spring meant giving lessons. The transmigrated Cao Sanqi decided to bring the most advanced productive forces to the backward ancient civilization. Thus, he told them what nuclear fission was, what nuclear fusion was, how steam engines worked… And so, the great demons whose cultivation had been stuck for a long time suddenly gained enlightenment and broke through their realms by applying modern knowledge such as nuclear fission and nuclear fusion… That very night… The vast and righteous demonic aura of Peach Blossom Spring soared thirty thousand miles into the heavens, and a scholarly demon of an entire generation gained enlightenment of the Great Dao. "Don't bully my villagers! Fight me instead!" Cao Sanqi spread his arms and blocked a group of peerless great demons behind him, preparing to face alone the top expert from the Demonic Sect, who was at the complete peak of the Qi Refining stage, and buy time for the kind villagers to escape. The Demonic Sect nobody at the complete peak of the Qi Refining stage, thinking: Big brother, you're bullying a demon now. If I so much as break a single strand of your hair, won't those things behind you wipe out our entire Demonic Sect? The demons, threatening with their eyes, thinking: Kid, you'd better know your place, or we'll wipe out your entire family! We'll slice even earthworms lengthwise! Pour boiling water into ant nests! Shake the yolks loose from every egg!
