Chapter 524, Attack on Gray Iron City_3

The effect was significant.

However, the dwarves on the city wall did not let out any cheers.

Their prided cannons, falling below, seemed more like stones tossed into the ocean.

There were ripples, but those ripples disappeared quickly, leaving no changes.

"Continue to load, continue to fire."

Boom! Boom! Boom!!

The cannons kept spewing, and the shells fell below.

But it still did not stop the advance of the undead, not even their rhythm.

Soon, the undead entered the designated second range.

The captains gave the order again, "Fire the Wind Pipe Cannons."

Thump! Thump! Thump!

Sounds like striking a copper pipe, mixing with the roar of the cannons.

The Wind Pipe Cannons began to fire.

This type of light cannon connected by five barrels, although less powerful than the regular cannons, when all five barrels fired at once, within a fixed range, it was even more effective than the regular cannons.

After all, it was sufficient to kill.
