The isolated door seemed to be smiling at him.
According to Renle Mountain's experience, behind such shopping mall fire doors are usually stairs. If this were an exploration instance, he would surely check out the door first, open it to see if there's a "stairway leading to other floors" as a new location.
But this is a Mysterious Dungeon with horror, where ghosts could appear at any moment, and death could strike at any time.
The road where the fire escape door is located is a one-way street. If, after entering, the door couldn't be opened and a ghost appeared at the only exit behind him, his life would end in this narrow passage.
So although Renle Mountain was somewhat curious about the door that might lead to other floors, he did not dare to approach it recklessly.
Better to go and check out the vending machine ahead first.
Renle Mountain walked towards the vending machine, stepping on the dust-covered floor.
