After hearing the words, Lu Ze and the others turned around. It led them to notice the presence of Wang Wenze and three more people. By the side of the latter group, Xilin was waving.
Lu Ze, together with his company, walked over while sporting a smile on their faces.
"Senior schoolmates, you three are over here at this base too?"
Wang Wenze then explained, "Every base needs powerful people to guard it. This is done to prevent ambush from the blade demons. When the battle starts, we won't be able to stay with you guys."
Lu Ze and the others nodded in understanding.
Wang Wenze's power was aperture opening state. On the other hand, Xilin's and Andrew's powers were approaching the aperture opening state. If they fought, the aftereffects of such powers could be enough to kill the surrounding soldiers.
This was the same for blade demons. Thus, the battles of aperture opening state and mortal evolution state were done in the sky.
