After Being Reborn as a Caterpillar, It Evolves by Devouring

The guy had a fever of 40 degrees and still insisted on playing games all night, but ended up dying. Accidentally reincarnated into a fantasy and mysterious world, full of swords, magic and various magical beasts. Fortunately he got the system, but unfortunately he became the weakest creature - a caterpillar! He can gain various abilities, skills, and experience from the monsters he eats, and then upgrade and evolve. Damn, what a rotten system! People who traveled through time were either princes or young masters from their clans. Why did I turn into a caterpillar??~Are you kidding me?? Even if I go to the underworld to starve to death and jump off monsters, I don't want to be a caterpillar~~~Oh my god!!~It smells so good~
