Ordinary person Lin Mo accidentally time-travels, waking up to find himself turned into a weak black worker ant. By chance, he awakens the colony system, relying on human thinking and engineering knowledge to lead the ant colony in resolving heavy crises such as floods, termites, and giant predators. Along the way, he meets the mantis time-traveler Ying, uniting various underground races to form a symbiotic alliance, exploring ancient progenitor ruins, and gathering evolutionary fragments to resist the invasion of the Devouring Insect clan. Forsaking the struggle mentality of the law of the jungle, he uses cooperation and win-win to build a secure underground home, writing an inspiring story of a weak creature rising up and growing.
