Online Game: How Am I, the Protagonist, Not Invincible?!

[Online game, slow burn, guild-focused, no harem, no invincibility, no brainless protagonist, not a power fantasy (a little rough early on, and I'm too lazy to revise it), enter at your own risk.]

With debt leaving him at the end of his rope, Su Ye enters the online game New Life and begins his journey to earn money and pay it off. Along the way, he meets the gang from Old Losers' Paradise. They usually enjoy the game and breeze through dungeons, but when they get serious, they can even compete with top guilds for world-first clears. Yet everyone in Old Losers' Paradise begins to realize that the more they play, the stranger the game seems... Dungeon battles, little to no romance, and a cast of characters who all have their wits about them.
