The Evil Clan's imperial sovereign Kou Fen heard Chen Fei's words and his eyes narrowed slightly, then suddenly burst into laughter, saying,
"We Evil Clans don't have that many Rule Crystals on hand, but if you have the guts, defeat one of my clan's early-stage Rule Integration Realm members, and you can choose any one of these items!"
As Kou Fen spoke, he waved his hand, and dozens of spiritual materials floated above the Celestial Wood.
The spiritual materials specially collected by an Emperor Realm powerhouse were basically all top-grade sixth-tier, and even the occasional mid-grade ones were rare and powerful.
Flowing Arrow Soil, blue-golden stone, Jade Flowing Bead...
Chen Fei looked up at these spiritual materials, each of which would be enough to provoke a fierce competition among many cultivators in the Rule Integration Realm if they appeared in the outside world.
