In the central area of the Ruel Beast Den of Old Dimension, there was a magnificent city built with three-hundred-meter-tall steel walls, and the walls were weaponized with magic cannons and magic turrets.
In this city center was a beautiful mansion called the Lord Mansion by the denizens, and right under this lord mansion was a massive underground plaza, and many small rooms were built in rows around a single glowing object.
It was a diamond-shaped platinum color crystal, and it emitted powerful undulation and rich energy into the atmosphere, making this place heaven for cultivators.
All those rooms around it were built probably because of this exact reason. That platinum crystal was none other than the Platinum Dimension Core of Ruel Beast Den of Old Dimension.
At this moment, the core suddenly trembled violently, emitting strong platinum waves as if it was agitating.
