@Owyn I mean, there's no easy way to make the two factions reconcile, he can only control the body and mind of one host at a time. Considering how hostile both factions are to each other, he can only choose one side or the other, so his best option is to just infect them, take their skills, and kill off one side (with the goblin side being more simpleminded and obedient, so... killing orcs it is, I guess).
@Owyn - Another way to look at it is how a virus naturally works. Why would a normal virus kill the host, when it is more beneficial to keep it alive? In this instance, the MC is honing their skill and playing with the limits of their own abilities. They could kill everyone involved if they wanted, as there is still some infected plants and the wolf left.
@ekickx Well the protagonist had the same name, reason for being reincarnated, power, etc. so yeah i guess there was someone but as i said to someone else --> I made my comment only on the basis of what i remembered
@Owyn Well, he can only control one target at a time, so he can't really make one of the two sides stop fighting, I guess he'd be better off knocking them out if he can, though, true. On the other hand, he can infect infinite targets so it's not like he Needs these orcs either I guess.
I never thought that having big, round eyes can be so scary, especially when attached to a hobgoblin. In fact I think it's the scariest part of this manga so far. But I wonder, can he undo his "buffs"? I mean, if left unchecked those buffed-up goblins would massacre lower ranked adventures...
