Military style drill to become an adventurer? This ain't fucking 'Nam.
Not that I'm against harsh training but if God wanted me to use skills, let me fucking use skills and train at the same time... Slave choker? Also what's with the "fellow adventurers"? I know teasing but that ain't teasing that's just mockery no matter how cutesy author drew it.
The moment I graduated from that drill I'd fuckin haul ass out of that shitty town immediately if they have to treat me like that for possibly a long time and leave them the fuck alone if there's monster flood or something.
Also MC looks you left your brain on Earth. That ain't damn cheat it's SKILL, GOD gave you SKILL. To USE.
You earned your shitty nickname..
