Jiushu did not understand the true purpose of Hanging gardens blueprint, nor did she understand why the glass ball is very much artificial until sunlight dawned on her in the middle of the night.
At exactly twelve in the night, the swimming pool lit up, as if it's spawning rare drop items in a cash eater mobile game.
Jiushu, who's extremely sensitive to light, woke up almost immediately.
She trudged over to the swimming pool by the oak tree.
The light is somewhat dampened by the water, but there is a floating light ball under the water, lighted up very much like the sun itself.
The temperature is freezing out here in the desert, still, the water is clear and warm.
Then it suddenly dawned on Jiushu. The glass ball absorbed every last bit of the sunlight that fell on it's flimsy wings.
