The Zombie System.

"I await your order." The warrior zombie’s voice rumbled through the chamber like distant thunder, sending a chill down Leon’s spine. There was an unsettling intelligence behind those burning eyes. This was not mere mindless animation; this creature could think, adapt, and kill with purpose.

Leon fought to maintain his composure despite the shock. "Kill the three. Leave their leader."

He gestured to his other undead. "The rest of you, stand back."

The Elite Grave Mage and assassin retreated to defensive positions. This battle was meant for his newest creation.

With a sudden burst of energy, the fight erupted into chaos.

Kalden struck first, golden energy blazing around his enhanced limbs. He launched into the air, his fist trailing fire as it slammed into the warrior zombie’s chest.

The impact sent shockwaves through the stone walls, and dust rained from the ceiling. Any ordinary undead would have shattered under such force.

Yet the warrior zombie absorbed the blow without flinching. Its mantis blade swept upward in a flawless counter, slicing through Kalden’s reinforced gauntlet as if it were paper. Steel and bone parted with a sickening sound.
