Tian Kui had perfectly completed the task of locating the victims, but Shen Xin wasn't done yet.
Shen Xin figured he could use Tian Kui's sense of smell to determine how deep the buried victims were.
It was a simple principle: the stronger the scent, the closer they were.
Tian Kui might not be able to tell the exact distance in meters, but he knew if something was near or far.
This way, the small excavator they had urgently borrowed from the next village could be put to use.
After all, a machine was much more efficient than digging by hand.
After a few scoops from the excavator, Shen Xin would lead Tian Kui over to confirm the proximity.
If they were very close, they would switch to digging by hand.
This method really improved their efficiency.
Qian Si Hai's eyes went wide as he listened, and he subconsciously glanced at Tian Kui.
Shiyao didn't have police dogs, let alone rescue dogs.
But the city had them, and so did the provincial capital.
