Reborn as an Ant, I Lead a Billion Ants in Defying Heaven to Cultivate Immortality

An entomology graduate student suddenly dies in the lab and opens his eyes reborn as a lowly worker ant without even a number. Luckily, he still has all his professional knowledge in his head: ant society, nest structure, predators' weaknesses, he knows it all! When a centipede breaks into the nest and the soldier ant captain sneers, "Worker ants, get lost," he turns around and leads seventeen battered soldiers to chew through the centipede's belly armor! He unites the underground and builds an empire, then leads the ants to the surface, only to learn that humans wield flying swords and demons become emperors, while calling an ant an "Immortal Speaker" is an insult. But he insists: even an ant can speak of immortality.
