章 669: 214. Hidden World Wizard

Suman Archipelago, Core Circle, Deep Sea Branch, inside Selena's study room.

Instead of a study, this place is more like a vast Magic Laboratory.

The Deep Sea Branch's castle is built on a mountain about a kilometer above sea level, with three main towers and more than a dozen auxiliary towers.

Selena's study is located at the top of one of the main towers, featuring a hemispherical stone dome, large windows, spacious balconies, and bright and gentle magic pendant lamps.

Above the dark blue carpet inside the room, floating a few meters above ground level, are more than a dozen miniature oceans with diameters larger than one meter.

The miniature oceans look like large water spheres with constantly rippling surfaces and shadowy fish swimming beneath them.

Beneath several miniature oceans, Selena closes her eyes and half lies on a soft sofa, supporting her head with her right hand, seemingly lost in slumber.
