What happened on the ground in the west of Weishui River was completely a holocaust.
After receiving the order, all the air cavalries just hovered above the east bank of Weishui River and monitored the movements of wing demons. Xuanyuan Fortress and the other human battle fortresses above air cavalries didn't make any response to it as if they had not discovered what was happening on the ground.
Right under Zhang Tie's gaze, tens of millions of Hua civilians were being killed. The death of these Hua civilians paved a "safety belt" with 6,000 miles in length and 24 miles in width for demons. All the landmines in this safety belt had been cleared by Hua civilians at the cost of their lives...
Except for Zhang Tie, the other air cavalries didn't know what was happening on the ground.
