After Ye Yuan entered the hole he had excavated long ago, he waved one hand through the air.
A piece of special glass custom-made for him by Huangyuan Technology appeared out of thin air at the entrance.
The glass had been custom-made to perfectly match the dimensions of the opening.

Not even an insect, let alone a grain of sand, could get in.

Only after finishing all this did Ye Yuan have time to extend his senses outside.
As his senses continued to spread, the situation inside the Blue Hole came fully into view.
The Blue Hole was now practically a cave of fog.
It had already been pitch-black, and now thick mist had joined the mix.

But what was this nonsense about it being absorbed?
