The entrance to the second floor was situated in one of the rooms that they had cleaned out. To be accurate, it was in the eighth room that they had cleared about two hours ago.
After cleaning up all the 16 rooms, the five of them returned to the entrance to the second floor underground.
The staircase was different from the first one as they were made of stone.
As they went down the stairs, they found out that not only were there scratches on the staircase but also on the walls beside the staircase. The scratches were of different depths. That being said, they seemed to be made by various monsters.
Seeing the scratches, Yi Yeyu frowned. "It seems like many monsters appear over here."
"Many of them are new. It's obvious that these scratches have been made within three days," Yi Zheng added, "This indicates that the monsters go out often to hunt for food."
