It's like solo leveling but the MC is not smart or cool and he won't get OP but he got a free virtual GF instead of a system given by a Gigantic Undead boss.
Read until Chapter 74, average story with average characters with below average art-style. MC is just a quest chaining player with no other unique qualities as a character. You would think that the author would put more effort in the story for such a simplistic art-style.
It's pretty good, like the artstyle, pacing and characters but really need more chapters 😬, it currently looks like the manga is doing monthly releases.
