Ovi greeted with a nod and then ignored Fang Heng, walking forward to place the golden sacrificial jar at the center of the magic array before starting to chant.
As the chanting continued, mental strength was infused into the magic array.
The ancient magic array slowly began to operate, triggering the crystal in Ovi's hand to vibrate along with the entire ground emitting a buzzing sound.
Fang Heng stared at the magic array, his brow furrowed.
He could feel it.
The natural energy of this world was being slowly gathered, then extracted through the special magic array on the stone slab, and finally concentratedly poured into the sacrificial jar.
"This world..."
Fang Heng muttered to himself.
The fluctuations in natural energy were minimal, suggesting that they had been extracted numerous times by the tree spirit tribe.
Was this a deserted world?
And then there was the crystal in Ovi's hand.
Nature's Heart!
