Who Do You Think You Are?

The protagonist is an extremely cold person who never looks anyone in the eye. Giving someone even half a glance is an act of grace. With combat ability at the absolute pinnacle, he travels through various small worlds. Against zombies in the apocalypse, one slap is enough. Against the insect race in a science-fiction world, it takes two. If someone annoys him, he draws his sword and charges. His mission is to help the people of each world take revenge. “Come with me” amid shattered walls, and “Stand behind me” in the abyss of despair, are all reasons for them to fall in love with him. Those who have benefited from his aid spontaneously follow him, but he merely says coolly, “Don't get in my way. Do as you please otherwise.” He was originally only a minor mission operative. It was through countless journeys across mountains of blades and seas of fire, amid bloodshed and violence, that he gained his undefeated strength. Endless travel brought him close to numbness, while repetitive plots turned him cold-blooded. Once he possessed his overwhelming power, he was even less willing to consider any other path. Yet the people he had once saved gradually taught him that the world could be conquered by means other than brute force. When the glaciers are melted by warmth, perhaps even after taking their great revenge, there will be no endless emptiness, because they are all there. Note: 1. At the beginning, the protagonist only knows how to fight and kill, so the pace will be very fast as he cuts his way through everything. Later, he will obediently follow the storylines. 2. The protagonist is an incubus. No one can resist him. 3. Respect the diversity of everyone's preferences.
