Top Ten Materials

Forefather Tian Yu looked at Xue Ying before chuckling, "You do not have to be in a hurry to go to the boundary of the void. It is too dangerous there. Most will pay a visit only when they reach a bottleneck in their combat power, or when they wanted to temper themselves. Fighting with the Destruction Devil Race is also beneficial since killing the Destruction Devils will actually prompt them to emit unique energy opposite that of ours. The moment we absorb such energy, it'll nourish our soul. This mystical feeling is quite similar to absorbing Origin World Rocks."

"Absorbing Origin World Rocks?" Xue Ying was startled.

Origin World Rocks. Those were condensed from the scattered energy after the primitive Ancient Sacred World shattered. It was genuinely mystical and incomparably precious. Even Cosmos Gods had use of it.
