not sure if I should praise the author for suddenly involving science after ignoring said science the whole time (all combatants should been poisoned from the smoke and heavily burned, ), and yeah, where is the danger of shooting a few arrows in their back?
but whelp, what am I doing, expecting logic or common sense here?
also quite irritating how the mc on the one side constantly whine about being only a student and the like but is still be able to fight calmly, making completly rational decisions, no problems with people getting killed in front of him and so on
