Don't Mess with the Little Bug

Lin Mo, a modern office worker, unexpectedly transmigrates into the wild world of the Classic of Mountains and Seas, becoming the most insignificant腐叶小虫. On the brink of death, he activates the Devour Evolution System. Struggling to survive at the bottom of the food chain, he relies on constantly devouring weak exotic beasts and accumulating essence to break through species limits, iterating his body and bloodline. Through five stages—hibernation and development, sweeping across a region, roaming the mountains and seas, contending for the top, and devouring the heavens—he successively devours all kinds of top-tier great demons and ancient exotic species from the Classic of Mountains and Seas. Ultimately, he devours all the ancient divine beasts, breaks the bloodline shackles of the Shanhai world, and evolves into the only supreme being beyond the heavenly way of the Classic of Mountains and Seas. — Description from novelcodex.org
