Zachary hadn't even finished collecting a few murals when one near the center of the passage suddenly reverted to its true form.
The creature across from him appeared humanoid, but with skin dark as ink. In the dead of night, stripped bare, an ordinary person might not see him, possessing a natural invisibility within the darkness.

In the blink of an eye, the Flying Swords stopped behind the opponent, who was still in a running posture, but the next moment, both of his legs were severed at the roots, and the upper half of his body fell heavily to the ground.
