"I wouldn't like somebody else's things in my room anyway," Aur thought as he took out a cushion from his storage ring and sat cross-legged, holding a high-grade mana crystal with a thoughtful expression.
The crystal had a crack in it and was slowly dimming out.
Although without the crack, one would think that the high-grade mana crystal was completely normal unless one used it for their own cultivation.
This was the reason that Aur was able to pull off his scam and use it masterfully.
Unless one cultivated with the high-grade mana crystal, nobody could find out since normally when one cultivated with a high-grade mana crystal, the crystal would crack the more time one cultivated with it.
The completely intact high-grade mana crystal was a guarantee already that there was full pure mana in it, but in actuality, due to time, the mana in it has long been slowly drained away and it could only be comparable to a middle-grade mana crystal at most now.
