"Here, Room Mystic-72." The administrator handed the key to Lu Yu, which was actually a token controlling the array within the retreat chamber.
Lu Yu found Room Mystic-72 and entered it.
The retreat chamber was very simple, with only a cushion placed in the center of the room.
The walls of the chamber were made of Tian'gang Stone, which even Martial Cultivators at the Core Formation Realm couldn't damage. Without the control token, no one could enter the retreat chamber. The walls were engraved with numerous arrays, as were the floor and even underground.
After entering, Lu Yu closed the door, placed down the Dragon-breaking Stone, completely sealing the retreat chamber. The arrays within the chamber activated, gathering Spiritual Qi. The concentration of Spiritual Qi rose rapidly, quickly increasing to three times the ordinary environment.
