Half an hour earlier, near the hotel where superpower users from the various regions were being accommodated.
Stein, wearing a brown coat, sneaked into a residence and, without hesitation, used a silenced pistol to kill the entire household.
He then went to the cellar and, wielding a sledgehammer, smashed a wall to reveal an ancient tunnel behind it.
The tunnel was covered in cobwebs, and the floor was piled with a thick layer of dust, indicating that it had been at least a hundred years since anyone had set foot in it.
Stein cautiously made his way to the end of the tunnel and saw a large metal door carved with patterns of eyes and tentacles.
At the bottom of the door, there was a stone slab with a nine-square grid, eight of which were movable tiles, and the last was empty.
Stein spread out his palm, where he also had a small cube that appeared to be the missing piece from the puzzle.
