Unknown to both Lin Mu and Duan Ke, five minutes had already passed. The hall was littered with pieces of broken weapons and even a few cuts, and scratches could be seen on the floor. Although the floor was made to be resistant to damage, it had still been slightly damaged from their attack, which said a lot about the strength that they had used.
But soon enough, under the influence of the formations in the hall, the damage started to recover. A few seconds later the entire hall was back to its former appearance, save for the fragments of broken weapons everywhere.
Lin Mu saw this and was amazed by this. He had not expected that the hall even had a feature like this. While the formations had activated, Lin Mu had observed them with his spirit sense and had found them to be different than that of those he had seen before. Evidently, these formations had different functions and thus had different designs.
'This is rather amazing.' Lin Mu thought.
