The Deputy Palace Master of Guigu, Chi Fenggu and others were obviously not ready to retreat. Most of their arrangements were within this city wall.

The cannon finally rang out on the top of the city.

After setting up the cannons, the sky-rushing gunners in the Song Dynasty immediately shot at the hot air balloons of Tongchuan Mansion in the air.

The shells shot towards the air.

There was a constant roar.

In an instant, only a group of fire appeared in the sky.

The defenders of Tongchuan Prefecture in the hot air balloon basket were blown to pieces by shells one after another.

The hot air balloons within the range of the sky cannon have suffered heavy losses.

This directly made the hot air balloon army of Tongchuan Mansion a little confused.

Someone noticed the Song Dynasty imperial guards on the top of the city and shouted in a daze: "Their cannons are on the top of the city!"

Only such sounds were drowned in the sound of gunfire.

The general in the army glared, but he didn't know what to do.

He could not retreat, but could only sacrifice the soldiers within the range of the sky cannon.
Chapter completed!
