@Balàzs Körmöci This kind of pill has different names in manhwa/manhuas. But I'm pretty sure it's either restriction to someone's ki, aura mana or whatsoever it's called so he can't use any enhanced martial arts, or literally a poison for mc. Another possibility is a booster for that fatäss son but we all know that that kind of trick always backfire. And considering how sinister that pill looks, it won't be simple.
I don't care about your taste!
