Ok I'm just rereading this cause I got bored and how tf did the MC struggled fighting against the Goblin General that is lvl 200 but in chap 2 the MC one shot a Bloody Ogre that is lvl 300.
I guess the mc will need to train for 1 Billion Years now just to win one guy,then train another 10 Billion Years to beat the next opponent,then train another 100 Billion Years to beat demon lord.....
