Before the sus drama overflows the forum, I have to mention first that this is a great chapter from both artist and author.
Nice detail, it has been a while I saw that counting method, one that lower your fingers starting from index. AFAIK, it is prevalent in older generation, which is totally fitting here.
Nice job doing the homework. Those bit about evolution theory is correct and already observed in nature on such a short live insects. And if you count viruses, of which already passed countless generations in each patient, it's already proven its effect on survival against efforts to combat them.
Actually, now that I mentioned it, the concept of passing down your skill to other also similar to how bacteria passes it genetic fragments with it's plasmid, if I remember correctly.
And that last goblin is as OP as fuk. Depending on its skills set, the last one could be unstoppable and totally capable to wiped out entire world by itself. It makes the demon lord looks like a puppy in comparison. If only there is someone received its skill, the world will never attempt to eradicate goblins ever again. Luckily, there is no goblin left to receive it in the first place, which also probably make it die virgin and lonely.
And about the sus drama, I don't know the fad so I can't get the joke, even though I can barely guess it. Totally against using the word.
