"Contact Lao Xie and the others and see where they are?" Ju Tianrui said to Xiao Jun next to him.

They cannot go to the northern border yet. They have to wait until the first group of people coming from the northern border arrives and send helicopters from the oil city to spray liquid nitrogen.

Because the first batch of people who were transported back from the North were too hasty, there was no liquid nitrogen in the helicopter.

If Li Qi and the others came here, it would be foggy in the oil city.

Ju Tianrui looked at the clear sky, the sun was shining at noon, and the sun was just right.

A little worried look on my eyes.

Ten minutes later, Xiao Jun hurriedly replied: "They have set out for two hours and are expected to arrive here in an hour."

"Okay, the headquarters base has tested the feasibility of helicopter liquid nitrogen spraying. Thirty minutes later, if heavy fog comes, you can let Yu Wei and the others fly the helicopter to the top of the oil city to spray liquid nitrogen, clear the fog, and wait for Li Qi and the others to arrive."

"Yes." Xiao Jun nodded.

"By the way, in terms of liquid nitrogen, you let someone hurry up and produce it." Ju Tianrui reminded.

Xiao Jun frowned and said:

"We have limited equipment here and cannot match the headquarters base. We have now started production with a maximum horsepower. However, if heavy fog comes, if all the helicopters in the oil city have to fly to the north, then we have to give them to the helicopters. What we can leave in the oil city may not be enough..."

Ju Tianrui gritted his teeth and said:

"It's okay. Once heavy fog hits, immediately ignite all the oil pits outside the fence!"
