Lord Sunkong smiled then.
He shrunk his barrier. The size was a lot smaller but enough for his people and for the canyons to be protected.
His people began to equip the canyons again. He ordered his people to move the canyons in three formations. When the canyons were prepared to fire at the right angle, Lord Sunkong lifted his barrier once more and fired!
Giant arrows rained over the Avians.
A few were critical hit and immediately turned into ashes.
Every formation had its weakness.
Lord Sunkong calculated it based on the first shots. So he moved his canyons to a direction where there would be a blind spot in the formation. And he had found it.
Once the formation collapsed, then this advancing Avians who had their whirlwinds as their shield would be defenseless in many directions. They would be a chicken ready to be slaughtered.
