Making a Stone Mill

Curtis's upper body transformed into its human form. His magnificent red hair fell over his shoulders and felt cool to the touch as it casually brushed against Bai Qingqing's arm.

Bai Qingqing couldn't help but glance at him. Her heart thumped erratically.

"What are you doing?" Curtis asked as he glanced at the odd-looking stones.

These stones looked different from the stones they made to extract oil. The two stones were round and had countless narrow grooves that looked like they were carved out by hand.

Bai Qingqing walked over to the stones and exclaimed in surprise, "Parker finished carving the stones so quickly. They seem like they can be used already."

Curtis tilted his head. There was confusion in his clear, red eyes.
