"An Energy Crystal for twelve hours?"
"Hall Master Lin, are you sure?"
Igor and Dona could not help looking at Lin Qi, feeling that he was joking.

Though he had never visited the Martial Artist Association's gravity rooms, he knew roughly how much they cost to rent.
One Energy Crystal a day was absurdly expensive.
Even now, with more than ten thousand martial arts hall disciples mining a small Energy Vein in Crimson Moon Mountain, they only mined an average of one Energy Crystal a day. That showed just how precious Energy Crystals were.

And he was desperately short on Energy Crystals. Players had too great a
