Gradually, as Noah pressed on, a subtle transformation overtook him. His movements became more fluid, his grip on the sword steadier, as if the weight of the weapon no longer burdened him
Unbeknownst to him, he had unlocked the sword's latent ability. "Unlocked" might not be the right term, as it was never locked to begin with; rather, Noah hadn't yet discovered the trigger for the ability. The sword, a near replica of the Zombie King, required recognition from its wielder, much like a king acknowledging his subject. He could have never known that to fully use the sword, he needed to give into his bloodlust, one of the main instincts distinctive to zombies whose only goal was to feed.
