Duan Rong reached for the carving knife in Xiao Yu's hand, but Xiao Yu flicked it away.
Duan Rong said, "Let me show you."
"You can do it?"
"Of course," Duan Rong said. "It's just like drawing."
Xiao Yu glanced at Duan Rong with suspicion, but she still released her grip, allowing Duan Rong to take the carving knife.
Duan Rong pivoted the stone core to the center, facing the cave entrance so that both could see. He glanced at Xiao Yu and said, "Watch carefully! Now! It's like this... when carving, only use the wrist, keep the elbow steady..."
Xiao Yu saw that Duan Rong moved quickly with one stroke, carving off a large piece, nearly changing her expression in surprise. Just as she was about to stop him, she heard Duan Rong continue, "...the lines have a flow... don't carve bit by bit, outline the whole contour first, then refine it part by part... like this... like this..."
