Previously, Zhang Yanhang estimated that he might need to clear an area above five square kilometers but less than ten square kilometers. Now, after actual measurement, he found that the area he needed to clear was indeed within this range, totaling eight square kilometers.
Currently, the area Zhang Yanhang was clearing was directly leading to the location of the slot machine. If he jumped down from this rooftop and walked left for more than a hundred meters, he would reach the alley where the slot machine was located.
The remaining three square kilometers was the area on both sides of the alley where the slot machine was located. This meant that if Zhang Yanhang just wanted the slot machine, he could go get it now. This was exactly why Zhang Yanhang wanted to go back to rest, as the most important slot machine was almost in his pocket.
