The CH-54's distinctive, deep propeller drone sounded once more.
This time, the cargo was concrete piles. A single twelve-meter-long, ten-centimeter-diameter pile weighed nearly a ton. Even with the CH-54's immense carrying capacity, it only dared to transport ten at a time.
After dropping off the concrete piles, the CH-54 immediately headed back.
Then came two medium-sized helicopters. Their carrying capacity was limited; five piles at a time was their absolute maximum.
Feng Mountain could only feel resigned to the situation.
The Far North Tundra was a vast expanse of frozen marshland with an extremely harsh natural environment. Combined with the Crown Territory's exceptionally remote location, it was impossible to transport such heavy materials by land.
Helicopters were the only option.
The two medium-sized helicopters cost $20,000 an hour.
It had only been two days, and Feng Mountain already had to pay $320,000 for helicopter transport.
