Metamorphic Reincarnation [LitRPG/Monster Evolution/ Isekai]

I'll die over and over again to save humanity (even though that's not really my goal and just a side-effect)! [participant in the Royal Road Writathon challenge] (much) more in depth synopsis: Our protagonist gain the ability to continuously reincarnate with completel memories AND the ability to keep one thing from each life permanently. This will, eventually, lead to extreme overpoweredness, but that's kind of the point. (Is this technically a powr fantasy? IDK, maybe. But i dont really cary, it is what it is). Also, there may be a bit of a subplot about saving humanity, but who cares about that. Basically, just an exploration of fantasy land. (also, spoiler, but the first reincarantion is as a caterpillar, from which we'll gain the metamorphosis ability, which is how the monster evolution element is introduced) Hugely inspired by In Loki's Honor, go check it out too, it's awesome!
