I, the Scavenger Ant, Swallow the Sky and Become the Emperor

Biological researcher Lu Yan died suddenly and traveled through time to become a scavenging ant at the bottom of the Black and Yellow Realm. While others cultivate immortality and overcome tribulations, he evolves through devouring. From an ant that was blown to death by the wind and trampled to death by its own kind, it devoured everything along the way until it swallowed the entire sky.
