Cerberus opened his eyes to see the monster had spawned again as the cooldown time of the floor had ended.
Zach, who was approaching Cerberus with heavy yet slow steps, sensed the presence of the monster and stopped on his track. He looked back to see the monster, but he didn't react to it.
The monster charged up and shot a laser beam at Zach, but instead of dodging, Zach opened his mouth and ate it. Even after five minutes, the monster didn't stop shooting the laser beam, and Zach had devoured it all.
Then, he raised one hand in the air and summoned hundreds of portals above the monster. And when he lowered his hand, the portal shot a black laser beam and obliterated the monster with hundreds of holes in its body.
The monster died after a few minutes, and Zach received 10% of the EXP he received the last time for clearing the floor.
