The helicopter kept flying north.

The flight speed reached 290 kilometers per hour, which was much faster than the speed of heavy fog blowing over.

"Okay, I understand, I will speed up to reach the Northern Federation."

Yu Wei squinted his eyes and answered to Ju Tianrui in the oil city.

Just now, Ju Tianrui contacted him and let him know that heavy fog was approaching in Oil City.

Time is running out, and he must reach the northern border as quickly as possible.

....

The other side.

Sanshu and others who set off from the Da Zhangshu base felt very uncomfortable sitting in the helicopter.

We kept flying at an altitude of 3,000 meters, but the surroundings were still foggy.

Driving without being able to see the situation ahead can be said to be the most frustrating and uncomfortable time for Lao Qin to fly a helicopter in his life.

The helicopter seemed like a lonely boat in the ocean, surrounded by the vast ocean.

"How far is it from Oil City?" Uncle San asked into the headset.

Lao Qin glanced at the electronic beacon, which showed his location, and then replied: "There is still about a third of the way, and we expect to arrive in an hour."

The third uncle nodded slightly, then closed his eyes and squinted for a while.

Under his feet, he kept stepping on a silver box. He had already opened the box and checked it. The medicine was all right.

Although he closed his eyes, his head was still spinning.

What he wanted to do this time was TC.

Although he looked expressionless, he was actually a little touched inside.

This was not unusual in ancient times, but now...

Thinking of this, he felt a little helpless.

They obviously gave the North many opportunities, but they still refused to give in and wanted to cause trouble. It's no wonder that Li Yu made up his mind to TC.

call--

The third uncle breathed a long sigh of relief and put his hands behind the back of his head.

Slowly fall asleep.

Lao Qin, who was driving a helicopter next to him, glanced at the third uncle next to him and felt a little pained.

They were three thousand meters in the air, and couldn't see anything around them. This uncontrollable feeling made Lao Qin's nerves tense all the time.

And the most important thing is that when we land in Oil City later, we don’t know whether it will go smoothly.

But just when he was so nervous and serious, the captain was sleeping, sleeping?!

So he was a little shocked and said to his third uncle with some doubts:

"Captain, how can you sleep at this time?"

The voice was not loud, and the third uncle didn't seem to be awake, so he didn't answer his words.

"team leader!"

Lao Qin said loudly.

"Huh?" Third uncle opened his eyes slightly, looked at Lao Qin with confusion and asked, "What happened?"

Lao Qin said helplessly: "Captain, how can you sleep at this time?"

The third uncle rubbed his eyebrows and said:

"Is it useful to be anxious? Is it useful to be nervous? Just solve the problem when you encounter it. Isn't it going pretty smoothly now?"

Lao Qin quickly asked: "Captain, aren't you worried that there will be problems with the liquid nitrogen when we land, or that the spraying effect is not good, and the field of vision is restricted, so we will not be able to land."

The third uncle frowned and said:

"Is there any use in worrying?"

"This hasn't happened yet. Why are you thinking about all this? Didn't it just go through a test in the base? The Da Zhangshu base is larger than Oil City. Even helicopter spraying is useful. Why is it useless in Oil City?"

"Old Qin, you think too much, drive hard. You were more reckless before than you are now."

After hearing what his third uncle said, Lao Qin was speechless.

What the captain said makes sense.

What shouldn't come won't come, what should come will always come, and if you encounter problems, just solve them.

Worrying about problems before they even occur is a waste of emotion.

They have already made preparations and considered everything they can.

Do your best and obey destiny.

Lao Qin shook his head with a wry smile, but after hearing the captain's words, his nervous mood calmed down a lot.

The helicopter keeps flying.

After a long but short hour, they finally arrived over Oil City.

But they couldn't see below and could only tell they had arrived by the position of the electronic beacon.

The third uncle picked up the walkie-talkie, contacted Wu Jianguo and Jackal in another helicopter, and asked them to spray liquid nitrogen downwards simultaneously.

At the same time, he unbuckled his seat belt and said to Lao Qin: "The helicopter is going around. I'm going to spray liquid nitrogen. If the vision is restored, you can start landing."

"good."

The third uncle quickly walked to the cabin. Originally, it would be more convenient to modify an external liquid nitrogen spraying device. They would not need to open the cabin door and could operate it directly from the console in the helicopter.

But that takes time.

I had no choice but to weld a stable liquid nitrogen spraying device in the cabin so that I wouldn't have to hold it with my hands all the time.

The third uncle pulled the liquid nitrogen spray pipe to the helicopter cabin door.

Secure the tube.

Crash--

He opened the cabin door.

It was high in the sky, the wind was strong, and thick fog blew in.

The third uncle quickly put on the protective mask and put the tube outward.

Unscrew the liquid nitrogen spray valve.

呲呲呲——

Liquid nitrogen was continuously sprayed out and scattered downwards.

The thick fog below continued to melt and dissolve as if it had encountered water.

Extremely fast.

below.

Outside Oil City.

The fire was everywhere.

Burning oil evaporates a large amount of water vapor, emitting light and heat.

Even surrounding the Oil City, there is a small ditch about two meters wide and only twenty centimeters deep.

These trenches have never been used since they were dug.

But as oil poured in, these small ditches formed a huge ring around the oil city.

Burning ring.

Anyone and zombies who want to enter Oil City must pass through this ditch.

The width of two meters is neither wide nor wide, but it is enough for zombies to be set on fire.

The smell of burning petroleum filled the air.

The oil burning outside was much better than Ju Tianrui expected.

This chapter is not over yet, please click on the next page to continue reading! The blazing flames evaporated a large amount of water vapor, so that even if liquid nitrogen is not sprayed outside the city, you can still see the situation outside clearly.

But the scope is limited to the area where oil is burned.

Ju Tianrui stood on the wall, looking at the humanoid zombies whose heads were burned with petroleum, roaring outside the wall while on fire.

Turning to Marcelon, he said: "Minister and the others have arrived. Has the area around the helipad been cleared?"

Marseille hurriedly said: "Everything has been cleared. I have notified everyone on the ground and told them not to come out for the time being."

"Yeah." Ju Tianrui nodded slowly, then looked at the thick fog in the sky.
