Chen Hai had made up his mind to follow Zeng Zhiguo's instructions.
He nodded and shouted at the workers who had been waiting by the side.
Soon, everyone started to move.
In the countryside below, the roads were mostly dirt. Although the location of Liuyuan No.1 Middle School was somewhat remote, it was still within the county town.
The ground at the school gate was paved with cement, but the layer of cement was not thick, just a few centimeters.
Swinging the big iron hammer and drilling holes in the cement floor with iron wire, and then prying with a crowbar, the cement began to fall off in pieces.
Zeng Zhiguo's workers were already adept at this kind of work.
After breaking up the cement floor, they followed Chen Hai's instructions and continued to dig downward.
It was said that in big cities, there were specialized machines for construction that could dig pits very quickly.
