Eliminating Evil for the People (4)

"I need to use this." Old Zao held a pitch-black ore in his hand.

"Is this black crystal ore?" Leng Ruoxue asked doubtfully. Why is this black crystal ore different from the ones I've seen before?

"This is a black crystal ore core I obtained by chance. It's extremely hard, and my flame can't melt it, so I need your help," Old Zao explained.

"Oh, then let's begin!" Leng Ruoxue said.

"Okay. Lass, use your flame to light the furnace for me." Old Zao sat cross-legged in front of the furnace.

"Okay." Leng Ruoxue released a small flame at her fingertips and threw it into the furnace. But the small flame melted the furnace in the blink of an eye…

"Ah! My furnace!" Old Zao exclaimed loudly, his heart aching. Boohoo… This was my best furnace! Wait, wasn't the girl's flame a divine flame? My master passed down this furnace, so it should be able to withstand divine flames!
