Slaughter

Lu Xuan saw boundless blood energies in the pool of blood below, surging into the vampires' bodies and rejuvenating their powers.

To put it precisely, the ancestral land of those vampires had become a small world on its own.

That small world itself had the power to resist the power of laws governing the entire planet.

As such, one could recover some bit of power above the planet's limit for a brief period of time within that small world.

That was how the sects and clans that isolated themselves from the world maintained their powers.

In comparison to many others, the ancestral land of the vampires was far more inferior and of a far smaller area. Even though it had the power to resist the power of laws governing the planet, said power could only be maintained for brief moments and nowhere near lasting long enough.

The vampires would have been able to rule the world in the era of total Spirit Qi dissipation otherwise.
