Within Lin Mu's perception, appeared a man who was clearly controlling the formation arrays of the entire city right now. He was sitting in the center of a large room with several statues that were channeling spirit Qi into the arrays.
There were runes inscribed on the floor of the ground directly while different ribbons hung from the walls, all carrying various formations on them, acting as additional complements of the entire array.
Just from all this, Lin Mu could tell that it was a rather complex array and one that would be very expensive to set up.
'It's on the same level as that of the sects… perhaps even the top sects might not have such formation arrays depending on the place.' Lin Mu thought.
But that was not all that caught Lin Mu's attention. He could also feel a steady stream of spirit Qi flowing into the man that was sitting in the center of the formations. The man was at the Dao Shell realm too.
