The crowd held their breath as the green machine couldn't be operated, and the master of stone cutting carefully took the stone off the machine.

The stone was small, only the size of a baby's fist, and cutting it was delicate work. The master was sweating on his forehead and didn't dare to slack off.

This was the first time he had cut a stone with green in it.

Bai Yan stared without blinking, afraid that the master would make a mistake and ruin his treasure.
