How Did I Become a Slime When I Was Reincarnated into Another World?

Ah? This cute, big blue lump, is it me? It looks pretty DuangDuang! Wait, no, why did I turn into a slime! Isn't this supposed to be my cool novel about another world? No, run quickly, people are watching you as soon as you arrive in this world! They treat me as an experience bag, so I have to hide quickly, secretly make a fortune, and then surprise everyone! "Not systematic", "Not smart", "Not invincible", "Happiness comes first", "Pure hand rubbing without AI" Seeing such a cute slime, there must be some kind people tricked into it, right? (Hehehe)
