Review Detail of Anime_lover21 in I Can Infinitely Synthesize Transcendent Genes

I love the book so far! I only have a few questions though. Is this harem or a single love interest? Also, not to be rude, but why is it locked at ch 19? I’ve noticed this with a lot of books lately where they lock way earlier than at ch 30 or 40 like they used to. I’ve been wondering why that is?
