I'm looking for epic scenes from novels/manga of the MC taking on entire armies, nations, and guilds alone. So so a list that's novel name and chapter #. I'm also looking for a specific scene. Seeing if there's a novel with something similar. The nation or guild or organization or party the MC works for or helps or befriends etc. ends up betraying him and sets up a trap like putting him in a scenario facing a giant wave of monsters. The betrayers turn up to the scene of the trap where they expect to find the remains of the MC or the MC super weakened (they're with an army to finish him off just in case), only to find mountains of corpses and the MC sitting on the leader/boss monster sharpening his weapons without a care or injury. MC turns to see the arrival of the army. He already knew what was up. The betrayers then knew at that moment that they'd fucked up. MC proceeds to bring hell upon the army and then on the organization/nation/guild.
