That Strong

Leon's battlefield was the most straightforward one.

After putting enough distance between them, the Vampire guard drove his sword into the ground, producing a bottle of crimson liquid—evidently blood. Simultaneously, the human man brandished his sword at Leon, assuming a protective stance.

To demonstrate his abundance, the Vampire guard continued to take out more and more bottles from under his armor, as if his chest were entirely lined with such bottles, akin to a soldier who strategically places spare magazines around their chest for easy access when needed.

Carrying a flask or any kind of blood container was a common practice among Vampires, as they required blood to perform their Blood Technique. This was why they had been dubbed the kings of battlefields; they needed blood, any kind of blood.
