Bab 322: Hint.

Yang Dao agreed to Ryu Jinshi's suggestion and before the time of the day ended, they left the Undine region and, using a similar teleportation channel, came to Gnome land. 

The first thing Yang Dao saw around him was a wall covered in pebbles. Yes, he found that he was standing inside a room and the walls were covered with white and black pebbles. The ceiling was a dome-styled one, covered with pebbles as well. 

This room seemed to have been a secluded place as well, as some green moss was visible between the pebbles on the walls. There were some places on the wall where a candle stand was placed. Ryu Jinshi said, "This is the standard architecture of the gnomes, master. They live in stone huts and pebbles. Well, you must know this from the book of life."
