looking for this manhwa

Hi! I'm looking for this manhwa and it was SUPER popular at the time. basically ppl got summoned, and first they go through a training trial but MC's levelling status was broken, so he was basically trapped at lvl1 in the pretrial grounds. mc lowkey went insane, stuck there for so long in isolation. he also got MAD buff with a large ass berserker sword. anywyas he eventually got to the fantasy setting he was summoned too. he also longs for fridges and modern day toilets and cannot access them bc his lvl is too low (he's constantly at lvl1)

he has a sidekick dude/mage who has long red hair and entire shtick is that he's a twink. he also meets like 2 dragons. they also fought this dude in a volcano or mountainside or smth whose powers were constant regeneration that's close to immortality.
