Chapter 449: Blood Exhaustion & Morale

"Blood Exhaustion!"

"What!? What is that!?"

"Blood Exhaustion! Burning one's vitality and lifespan in order to gain strength surpassing your realm.

If done normally, and willingly from the person itself, one could burn up to 75% of their vitality, and blood volume in one attack, or through a period of time.

No one is able to expend more than that though, as it's the soul's prime instinct to secure its physical vessel continuation, and 25% is the smallest possible volume limit.

Even then, it's impossible to gain strength beyond one's Realm, as the vessel still belongs to a lower realm.

It's the same as burning rocket oil in a small car. The combustive power of the oil would make the car run faster, but that speed would just destroy its structure.
