"Attack!" Without wasting any words, war between monsters and NPCs always erupts upon contact, unlike the wars among human beings. Both sides typically don't engage in much conversation. At this point, when the puppet master led the other monsters to the battlefield, he didn't feel like wasting words with those NPCs. With a wave of his hand, the monsters immediately launched an attack on the NPCs.
Upon seeing the monsters' reaction, the NPCs were not surprised. They had probably witnessed such situations numerous times. Seeing the monsters rushing towards them, these NPCs remained calm and began to defend themselves according to their military officer's orders.
A massive amount of arrow shafts were fired from the NPC faction before any hand-to-hand combat started, flooring a batch of monsters en route to the attack.
However, the monster faction wasn't going to stand idle after the NPC faction's offensive.
