This type of catapult relied on elastic force for launching and had a short range, only about a hundred meters. However, its small size and fast firing speed were its advantages.
"Whoosh whoosh whoosh!"
Hundreds of gunpowder balls flew more than a hundred meters, crashing into the army of twenty to thirty thousand that had charged to the base of the city wall.
"Boom boom boom..."
The fierce explosions sent countless steel pellets flying.
They reaped thousands of lives.
Soon, the second round of shelling had been prepared!
However, Suo Lun did not use cannon grape shot to attack the enemy of twenty to thirty thousand below the city wall, but instead, he used solid cannonballs to attack the enemies eight hundred meters away.
That area was more crowded, and he could inflict maximum carnage.
As for the group of twenty to thirty thousand at the foot of the wall, let them charge if they would!
"Boom boom boom boom..."
Hundreds of cannons roared once more!
