Ying Yan satisfyingly moved all of the earth essence crystals from the essence milk pool into the jade bottle.
These extremely hard and heavy crystals were the purest essence of the earth energy and only a sesame-sized crystal piece weighed nearly a million 'stone', not to mention that these crystals had countless magical usages and effects.
If magical treasures were made with these earth essence crystals, the finished magic treasures would be especially heavy and incomparably powerful; only peak-level and above Senior Magi could use that kind of a magic treasure freely. Weapons and armours that were forged from ordinary metals would shatter into ashes once touched by magic treasures made from the earth essence crystals.
