Seems like a magic version of "The Legendary Mechanic" except theres no background to the MC, just wakes up in the game. MC barely gets his first quest 10 chapters in and completes it mostly solo, agaisnt an npc twice his level who takes more than 24 hours to heal and regain mana. Also takes the MC several weeks to get to level 10. Just under 3 months. the majority of game the 1st 10-20 levels can be gotten anywhere from 5 to 6 hrs to 1 week. just not getting drawn into the story.
