Ye Xiao and Han Bingxue were walking at the back. In the dense fog, they couldn't see, so they didn't know how far they had traveled. They had at least walked in the fog for an hour before they smelled something like musk.
After they took a turn, Erhuo stopped.
Ye Xiao still couldn't see things. He reached out his hands and Erhuo just tactfully jumped back to his hand. When it jumped on his hand, it felt a bit different than Ye Xiao expected. When he touched Erhuo in the hand, he realized Erhuo just jumped back from a stair. It was a bit higher than he expected, so it felt different.
On the stair, there was a door.
The door was the only thing that wasn't covered by the fog in the third layer so far. It was the only thing they saw in this layer!
Ye Xiao and Han Bingxue stared at the door. It was not gold or wood, but they both could feel the toughness of it. They knew that no weapons, no matter how sharp, could break the door.
