The Underground Area of Moonshadow Breath Castle.
The Underground Area was divided into five districts: the Blood Food District, the Holding District, the Equipment District, the Transformation District, and the Blood Brew District.
The most vital of these was naturally the Blood Brew District.
The Blood Brew District was responsible for supplying food to all the Blood Slaves and vampires.
More importantly, it bore the responsibility of providing Moonshadow Breath with sufficient blood energy.
The Blood Pool at the center of the Stone Chamber where Moonshadow Breath resided could constantly generate ample blood energy.
The key to that lay in the Blood Brew District.
The blood of Bronze Tier creatures, brimming with spiritual energy, was an indispensable ingredient in making Blood Brew.
Some spiritual energy was inevitably lost while transporting this blood and brewing it.
The Blood Pool became the ideal destination for that lost energy.
It could be said that the Blood Brew District directly supported Moonshadow Breath's foundation.
Precisely because the district was so important, a Silver Tier creature guarded it year-round.
At that moment, Royal Alchemist Harmon was carefully inspecting the Blood Brew Vat before him.
The Blood Brew Vat was an enormous hexagonal crystal-glass vessel, one meter in diameter and three meters tall, with bright red blood churning inside.
As the blood churned, its impurities were gradually removed, while its spiritual energy reacted with the blood on a deeper level.
The final result was Blood Brew rich in pure energy.
Finished Blood Brew served as food for vampires and the elite Blood Slave Guard.
High-Grade Blood Brew was reserved exclusively for Moonshadow Breath.
As for the ordinary members of the Blood Slave Guard, they could only consume the residual dregs left over from making Blood Brew.
The class divisions were clear, and the hierarchy was strict.
