Jiang Yi and He Lao were wandering in the maze aimlessly, and every time Jiang Yi walked into a palace hall, he would retrieve a piece of wooden block in the Fire Spirit Pearl and throw it in the corner. Furthermore, the length of the wooden blocks would all be different, helping them have an estimate direction.
As a result—after going through over a dozen halls, they didn't encounter any of the repeated palace halls. It was apparent that there were countless halls in this maze.
"Eh?"
When they entered one of the halls, Jiang Yi and He Lao's eyes lit up a the same time. They noticed a set of skeleton in this palace hall, and it had eroded. There were plenty of tiny holes in the bones, and it was obvious the victim passed away for many years.
"Someone came before! It might be Yun Lu!"
