In the dead of night, inside a teacher's apartment at the Royal Academy of Luminous.
A ghostly and wolfish aura of Shadow power suddenly erupted. Under the control of the black-haired girl, the scarlet energy enveloped the entire room she was in.
The "Nether Realm" which blocks outside perception, quietly opened.
After ensuring that no one outside could detect what was happening inside the room, Yumo slowly raised her hand and took out a delicately crafted blood jade bottle from her spatial ring.
This blood jade bottle contained what was essentially the compressed extract of several tons of dragon crystals.
Dragon crystals are the essence of the dragon race's strength, and this bottle of concentrated dragon crystal essence contained an extremely terrifying power.
Even the slightest breath escaping from the bottle's mouth could easily crush the soul of an ordinary person.
