Lu Shijing took the metal detector and examined it. All the little gadgets in Gu Shengsheng's bag were quite handy.
Then he said, "It's not broken. It must have detected something with metallic elements under the ground here."
Gu Shengsheng grew curious as well. 'The metal detector is reacting so strongly. Could it be a gold mine... or some other kind of mineral deposit?'
Gu Shengsheng walked in a small circle with the detector and found that the signal was strongest right where she had dropped her bag earlier.
Lu Shijing stood to the side, marking the locations for her.
Then Lu Shijing said, "There must be something down there. We could use a hoe to dig a bit and see what it is."
Gu Shengsheng said, "Let's go to the grave first. We can come back to dig later. We shouldn't keep Grandma waiting."
"Okay."
Lu Shijing then said, "I'll help you out over here. You go on to the grave."
