Ling Feng stared intently and saw two snowmobiles approaching!
"I didn't expect they'd bring these things on the truck?"
With a chuckle, Ling Feng stayed put.
The two snowmobiles sped past him, traveled a few dozen meters ahead, and then stopped.
All four people got off the vehicles, took out two metal boxes, and retrieved items from inside.
Upon seeing it, Ling Feng realized that the equipment was similar to what Mu Yuhan carried, and he narrowed his eyes, instantly understanding.
Like Mu Yuhan, they were here to collect signals.
However, these people did something different; they not only brought instruments but also two metal rods over a meter long.
The length and thickness resembled crowbars, but Ling Feng didn't know what they were for.
As he pondered, one of them took a large hammer from the snowmobile while another held the metal rod, its tip piercing the ice surface!
"Ding!"
