Zhang Lang, a genius scientist, was reborn as a cockroach after an accident. Starting with a tiny roach nest in a kitchen, he steadily built up his power. He braved the neighborhood trash bins, cleverly cracked the refrigerator system, and outsmarted a tribe of mice. The cockroaches under his command steadily grew into an empire: an agricultural roach society in the neighborhood gardens, an industrial revolution in an abandoned auto repair shop. The roaches built their own tanks, planes, and cannons, and even created cockroach doomsday mechs! But the cockroaches of Longguo would not stop there. They marched across the land, conquering every cockroach on the planet!
