322 Leakage of Electricity?

'BOOM!'

A series of terrible explosion sounds reverberated through Fallen City!

Even the zombies outside of the wall were attracted to the sounds.

The survivors present had all witnessed what happened! When the two sides were about to collide, the minibus released a formless airwave which struck the guards and their vehicles directly! It left everything in ruins.

Diao was almost shocked to death! He too had witnessed the whole process, but he was unwilling to face the cold truth. Moreover, the formless wave, which had yet to dissipate, was currently moving toward him! 

"What is this ghost...!?" Diao was stunned. He had taken plenty precautionary measures, but the outcome…

Then, he noticed a black muzzle out of the minibus… Why!? Why did the minibus posses such a weapon!? No wonder the vehicles could not withstand the air wave's impact at all.
