What caught Luo Lie's interest was one of the five stone walls standing in the corner.

Each of the five stone walls was carved with a different martial technique.

What attracted Luo Lie was the Great Wheel King Seal carved on one of the stone walls.

The Great Wheel King Seal was a martial technique created during the Shattering Stage by Kong Xuan of the Peacock Dao Sect, who is known as the foremost person below the Saints. It is said to be among the top ten martial techniques of the Shattering Stage. It's important to note that the most powerful techniques of this stage are usually created by Saints during their Shattering Stage, which speaks volumes about the extraordinary nature of Kong Xuan from the Dao Sect.
