"This hole was previously covered by a stone!" Bian Dong translated for the discoverer."If we don't look for it deliberately, it's not easy to find!"
"Yes ..." Zhao Yu nodded as he measured the distance between the two small holes and their positions. After weighing the pros and cons for a few seconds, he raised his arm and said,"keep looking!"
Thus, everyone began to dig the ground again.
Although no one knew what these two small holes represented, everyone was looking more and more enthusiastically.
After a while, another police officer raised his hand. He found another small hole a dozen meters away.
Very quickly, the good news came one after another. Including the one that Zhao Yu had found, the group found a total of five identical holes in the open space!
Zhao Yu quickly found that the positions of the five small holes were not irregular, but there was a pattern to it.
