Que Lingfei thought for a moment and said, "I want mid-grade Demon Essence Pills!"
"Sorry, I can't refine mid-grade Demon Essence Pills yet," Yang Zhenshan slightly shook his head.
It's not that he couldn't refine mid-grade Demon Essence Pills, but he couldn't guarantee the pill-forming rate for mid-grade Demon Essence Pills.
When refining second-order low-grade Demon Essence Pills, he could guarantee a pill-forming rate of over 70%, but for mid-grade Demon Essence Pills, he had to rely on luck. If he was lucky, he could refine a mid-grade Demon Essence Pill using low-grade Demon Cores; if not, even using mid-grade Demon Cores would be futile.
"Alright then, give me ten Demon Essence Pills first!" Que Lingfei said.
Yang Zhenshan's mouth slightly opened in surprise; this person really had deep pockets.
"I only have three on hand right now, including the one you have!"
