"Lord, it's a dead end?" Skinorse gaped at the spiraling steps.
The first Magic Door was in the near distance. He walked up and tried with his dagger. There was a sharp scraping sound, and a faint scratch appeared on the smooth Magic Door. It faded slowly and disappeared completely after three seconds.
"This door isn't very sturdy. I can destroy them easily, but there are too many." He estimated that he could force through five doors, ten doors, and even 20 doors but 50 would exhaust him.
Link had a headache too.
The reason was simple. The space in the spiral steps was very unusual and was finely folded multiple times. Only one of these doors was the true exit, but its position wasn't set. It could randomly appear as one of the 50.
In the previous game, Link had tried more than 100 times. Every door had once been the exit, but as a player, they could only gamble their luck.
