Under the doubtful gazes of the crowd, Cheng Yunlong operated the machine, carefully cutting the stone along the lines Zhao Yuan had pointed out.
An ear-piercing BZZZZZ filled the air, accompanied by a cloud of flying stone chips and dust, making it impossible for the onlookers to get a clear view of the stone as it was being cut.
Soon, Cheng Yunlong had cut to the depth Zhao Yuan had requested. He paused the machine, preparing to reposition the stone. He needed to cut it from another direction to complete the second line Zhao Yuan had laid out.
But as he was repositioning the stone, his gaze suddenly fell upon the deep groove he had just cut. He visibly shuddered, and a look of utter disbelief washed over his face. Disregarding his hands, which were caked in dust and stone chips, he rubbed his eyes hard. Then, he carefully lifted the stone and stared intently into the groove.
"What is Old Cheng doing?"
"He didn't actually find jade, did he?"
