Evolve Infinitely from the Contract Cockroach

At the beginning of the story, I just accidentally contracted a cockroach. Evolved super regeneration. Do you think I will go around protecting the world like a superman? No, I just want to live peacefully and well. But I don't look for trouble, trouble always looks for me. I had no choice but to accidentally swallow a praying mantis, evolve serrated mantis arms, accidentally swallow an eagle, evolve short-term flight, and accidentally... After swallowing this, swallow that. After swallowing yours, swallow his. Now I am invincible, are you satisfied?
