Is this the tutorial tower of the advanced player?
Also there is the survival of the sword king
Also known as Otherworldly Sword King's Survival Records
Oh yeah i think that is the one he is referring to.
Hey, the story kinda reminds me of another manhwa where the MC was also trapped in the system error for a very very long time and he keeps getting back to level 1 after reaching level 5. And he was supposed to be transferred to another scenario after reaching level 5 but cause of the error, he was trapped in there and...well he basically gets stronger by killing monsters repeatedly.
