Review Detail of troutrun in I, Who Have Been Reborn as a Poison Dragon, Am Being Persecuted by the World

So far the story is not too bad (up to ch 40). The MC is primarily focused on growing up (stronger) while being overly cautious to avoid being found. There are no face slapping, system or other usual trope present. MC transmigrates into a baby poison dragon and awakens the ancestor bloodline which grants him the ability to absorb traits/skills from things that are consumed. The only negative or annoying thing so far is probably the MC's lack of taking advantage of his OP skill. He can absorb skills/traits from things that he eats and even the story description hints at this but so far he refuses to eat any intelligent creatures (humans and mermaids) to obtain their skills. The author seems to want to nullify this skill by bringing up compatibility issues that does not make much sense. Our MC's biggest obsession is to eat a freakin lava rock. ugh...
