475 Soaring Cultivation

The ninety percent primeval sea in the aperture surged with high waves, and true gold primeval essence shone brightly on the aperture walls.

The aperture walls were also extraordinary; sparkling and clear like crystals, containing life force in them. This was the crystal membrane of rank four peak stage realm.

Waves continually surged, reaching towards the sky. Then, they crashed towards the crystal membrane wave after waves.

At first, the crystal membrane was like the reef of a sea, being unmovable. But it gradually became unable to endure the fierce waves and cracks started appearing.

As time passed, bigger cracks appeared.

The primeval sea slowly reduced, while the crystal membrane was full of cracks and appeared extremely fragile. However, there was still a little distance left from breakthrough.

Fang Yuan was sitting cross-legged on the bed with both his eyes closed, and almost all his attention was on the aperture.
