Wo Bushi Da Mowang

A man finds himself reincarnated in another world as the Demon King Overlord, tasked with destroying humanity. He insists he is a pacifist and denies being evil, claiming he has no desire for conflict. After accidentally killing a thousand human soldiers with an energy blast, he blames a relic and insists it was a misunderstanding. He expresses frustration at the situation, claiming he doesn't want to cause harm and wants peaceful coexistence. Despite his protests, others continue to see him as a threat. He grows increasingly exasperated, shouting for people to stop bothering him while still insisting he is not the Overlord.
