Sometimes, even the rocks under the grass or an inconspicuous depression, Feng Yi could discover and remind everyone to pay attention.
The village chief and his companions looked at Feng Yi with increasingly astonished and uncertain eyes, but their concern for their grandson's safety was paramount, and they suppressed their urge to speak out.
As they were about to reach the forbidden area, the village chief was about to speak when Feng Yi suddenly stopped:
"Is that his item?"
Feng Yi's flashlight beam pointed to a spot on the ground.
The village chief's son hurried over and found a wooden whistle on the branches of the bushes ahead, exclaiming excitedly, "It's his!"
As he spoke, he took out another wooden whistle and blew it rhythmically, sounding like some kind of bird call in the night.
As they had searched along the way, they would occasionally blow the whistle in this manner.
