章 399: Key

Accompanying this loud sound, the ground surrounding the throne actually started to crack!

With the throne as the center, the cracks expanded in all directions. Then, something seemed to be flowing out of the cracks.

Chu Liuyue focused on it and realized that it was actually… golden sand!

Countless particles of sparkling gold sand kept flowing out like fountain water, but the sand didn't flow outward in all directions. Instead, the sand gradually accumulated upward!

Chu Liuyue then realized that it wasn't actual sand but crushed crystal pieces!

Those tiny crushed crystals gradually gathered together and presented a strange, heptagon-shaped, and thin, nail-sized crystal.

Those thin heptagonal crystals connected to each other and formed layers in an upward manner.
