Don't worry.cool you guys can drop this series now then.
MC finally had a cool moment tho I quite liked the "that time is mine and hers only" line.
So many hypocrites hating GDS and still reading their chapters!
Usually I feel the same, especially when the MC essentially doesn't have to do anything, but I think this manga can be interesting from the standpoint of actually using the massive training timeskip.idk I kinda hate overpowered MCs but I'm fine with this guy so far because he doesn't fuck around and act clueless like all the others.
You have a point on the numerical value being exaggerated, but there are two things that might come into play, in my opinion (besides an author being too liberal with numbers ,obviously).
A) EVERY life counts, no matter how small, hence even killing an normal ant colony or a bee hive gives him as many lives as the insects within said colony or hive that could amount in the thousands in one go.
B) The enemy hero is the one who exaggerates the number of lives he has and is bluffing in order to make his opponent give up/lose hope. And in truth he has a much smaller number like a few hundred or thousand.
I did think about it, but that number is just so huge that even big AOE spells don't seem sufficient to justify it.AOE spells and mass army murders are common in the isekai worlds these people are sent to. wouldnt surprise me if hes been part of massive genocides in the name of the "Goddesses" in charge of the school.
