When he arrived at the battlefield, Isaac saw his monsters being beaten back by the human soldiers. They were bombarded with hot bullets, every part of their bodies and organs splattered on the grass. The scene he witnessed looked more like a massacre than a battle.
Yet, Isaac grinned from behind his mask.
He ordered all his monster warriors to charge forward. Five thousand beasts roared, shaking the air, before they finally dashed over the sloping plains overgrown with grass.
On the other hand, the human soldiers felt the ground shaking. They quickly looked for the source of the sound. Instantly, their eyes opened wide while looking at thousands of monsters with ugly forms rushing from the highlands.
"Watch out! The second wave of attacks is coming!"
They stopped chasing after the retreating swarms of monsters. Instead of running away, they held their position and pointed their weapons at the enemies.
