In the middle of nowhere, Mark was sitting on the grass in lotus position with dozens of ether crystals poured beside him.
"System, Absorb."
He was taking one of them into his hands, absorbing all the ether energy from it, and took the System's help to refine it.
Within ten minutes, all the sixty-seven ether crystals were absorbed and refined, increasing his ether energy points from 359 to 426.
"I see, low ether crystals only raise 1 point, huh. No wonder it is too tough for the Spirit Warriors to raise their level in a short time." Mark mumbled to himself while taking a look at his stats.
After calculating how much it costs to reach 7-circle, Mark threw away the silly thoughts and proceeded to open the currency exchange tab.
*Ding! You exchanged 2500 gold coins for 500 credits.
"System, open the store."
A list of categories appeared before him. "Items, Attributes, and Skills."
He clicked on items.
