It didn't take long for a restless sound to come from the dense forest ahead.
"Brothers, the monster is here!"
There was no need for a special reminder. The believers already knew that the monsters were coming. On the top battle platform, the cannons had already let out a roar.
The Heaven's Wall city's terrain was quite high. A few specially-made rune cannons could send the cannonballs far away.
Cannonballs whizzed out one after another, causing people to cover their ears subconsciously. They had to wait for a while before they could hear the loud sounds coming from the forest in the distance.
These specialized weapons could bombard monsters from a distance, but they needed to be guided when attacking, otherwise it would just be a waste of ammunition.
The runic airship was in charge of guiding the monsters. It was hanging high in the air, keeping pace with the tide of monsters.
