Despair flashed in Gui Che's eyes. He knew he was no match for a Quasi-Sage; if he failed to escape, he would undoubtedly die.
He reached into his robes and pulled out a fist-sized black bead.
It was the low-grade Innate Spiritual Treasure, the Black Flame Pearl, which he had obtained in his early years.

Quasi-Saint Xuanyang's expression changed. He had not expected Gui Che to have such a trick hidden away. He immediately retreated and summoned a defensive treasure to block it.
"Boom!" The Black Flame Pearl exploded with a thunderous crash, black flames sweeping across Flowing Cloud Island like a tsunami.
