The B-tiers only realized it now. The cannons were not only aiming outside but were pointing inward too.
More so, the grade of the energy cannons was similar to that of the Bei Hua—B-tier energy cannon.
In other words, one blast of this cannon was sufficient to put down a B-tier mutated beast, not to mention its effectiveness against aptitude users.
More importantly, they had simultaneously heard the noise of cannon stretching out from the direction of the Floating City. Their consciousness and senses told them that those cannons were currently focusing on the room they were in.
Silver radiance hovered around Bai Li. The B-tiers recognized the radiance to be spatial runes.
They knew because she had used the same runes to teleport them a thousand meters away from the Cinder Pine in the previous battle.
