The first thing that caught the eye were two "hills" almost touching the vault's ceiling!
One was formed by countless sharply-edged energy crystals, with a shimmering aura flowing inside them.
The energy waves emitted by such a quantity of energy crystals caused the surrounding air to distort slightly.
Although a single energy crystal might not be a world-class treasure, they are hard currency across the planar barriers.
Whether used to replenish consumption, power facilities, or serve as trading currency, they are extremely valuable.
The crystals before them were of exceptionally high purity, with an immense internal energy capacity, far surpassing ordinary goods.
The other hill was even more captivating — it consisted of countless irregular-shaped crystals that seemed to have mist swirling inside, emitting a chill and allure that acted directly on the soul.
Soul Crystals!
