Sovereign immortal aperture, Mini Purple Heaven.
A faint purple light was shining in the haziness.
In the vast sky, there was a floating eagle nest.
This eagle nest was like a three-storey building, there were no doors or windows, it was like a huge crystal.
A type of translucent crystal, twice as thick as a human's forearm, interlinked with itself, forming this tight eagle nest that had the same color throughout.
This crystal was extraordinary.
Fang Yuan had recognized that this was heavenly crystal, a rank eight immortal material!
Heavenly crystal came from the sky, it was very light and could float in the sky, it would never fall to the ground unless there were external forces.
Regardless of what was inside the eagle nest, just the outer nest itself contained five hundred kilograms of heavenly crystals! Just this heavenly crystal alone had immense value.
