As Saleen sighed, the six meter long green current had already disappeared completely into the wall. This wall was over twenty meters thick and its thickness was not the same all the way throughout. The outside of the wall was as flat as a mirror while inside it was uneven. At the thinnest part, it was around twenty-four meters while the thickest part was nearly thirty meters.
With the wall being this thick, even if it was not built from the metallized steel rocks, it would not be able to be destroyed by the metal hammer. Bifano did not have any powerful mages among his men and they could not measure the thickness of the wall.
