Wyvern (2)

Crack...

As the Wyvern devoured the Yeti, I kept my gaze fixed on its scaly body, searching for any hint of a change in the color of its scales.

Wyverns have the ability to evolve and increase their Rank by feeding on other creatures, and the color of their scales indicated their level of strength, with white being the lowest and abyss black representing the pinnacle of power.

At the moment, half of the Wyvern's scales were a deep shade of crimson red, indicating that the creature was likely at E Rank. This was already above the typical standard for an F Rank Dungeon Boss, making it a formidable opponent.

I dared not make a single movement, and instead focused on slowing down the speed of my Mana circulation to avoid attracting the Wyvern's attention. The process was excruciatingly painful, as forcibly decelerating my Mana caused me great agony.
