Five months later, Lin Xiao officially put the fortress core into the valley.

Only the fist as big as the crystal core is put down, a layer of crystal light blooms, spreads rapidly, and soon forms a house like a two-story building.

Light and shadow condense into a small building made of translucent material like crystal. This is the core of the fortress. As long as the house is destroyed, the fortress will be broken.

The fortress core just put down has only level zero and only a few simple functions.

Hundreds of demon wizards surrounded a supervisor and united to condense a huge green light to fix a leader Bing FA. They saw the evil energy gushing from the leader ice mage almost with the naked eye. He was quickly corrupted by the devil's power.
