"Call the headquarters. We encountered an Oil City helicopter eighty kilometers outside the Federation. We are now pursuing it. Please ask for support!" The observer used a military radio to urgently contact the Northern Federation.

In the Northern Federation.

Yuan Liming from the Communications Department was shocked when he received the news.

Stumbled to Governor Yuan Zhi's office.

"Cousin, there is news from Huo Jian who is on a flight patrol outside today. They have discovered an enemy plane in Oil City eighty kilometers away. They are now chasing them. They are asking for support!" Yuan Liming said breathlessly after coming in.

"What?" Yuan Zhi put down the towel in his hand and his expression changed drastically.

He frowned tightly and immediately said to Yuan Liming: "Notify Han Li and ask him to send half of the helicopters to pursue him."

"Okay!" Yuan Liming immediately turned and left after hearing this.

"Wait!" Yuan Zhi suddenly shouted.

"You just said, Huo Jian and the others discovered how many helicopters from Oil City?"

"Um...one piece." Yuan Liming thought for a while and replied.

Rumors were flying all over the Northern Federation, and Yuan Liming naturally heard some of them.

He had a sense of fear about that mysterious oil city. In this anxious state, he suddenly received news from Huo Jian, which made him a little confused.

After hearing Yuan Liming say there was only one helicopter, Yuan Zhi thought for a while and asked: "What we sent out was not a helicopter, right?"

"It seems to be two patrol planes. Cousin, you just gave the order yesterday." Yuan Liming said.

Yuan Zhi did not answer immediately.

He held the hot towel and walked back and forth in front of the table.

After pacing for about two minutes, his eyes narrowed and he said, "Don't let Han Li reinforce us, and let Huo Jian and the others come back!"

"Ah? Why?" Yuan Liming was a little confused about Yuan Zhi.

Yuan Zhi said angrily: "When you hear the order, execute it immediately. How many times do you have to ask me to say it again!"

Yuan Liming saw his cousin getting angry, so he shrugged his head and said quickly: "I understand, I'll inform you right away."

After saying that, he left the office.

After he left, Ma Song's eyes flickered, and he approached and asked, "Governor, are you worried about an ambush?"

Yuan Zhi nodded and said, "Well, Fan Haiyang said that there are at least four helicopters in Oil City. Even if not all of them are sent, there is definitely more than one."

"Since there is more than one helicopter, but only one helicopter flew over rashly, it means that the people in Oil City must have other purposes. Maybe this is just a bait. Their real purpose is to lure all our helicopters out.

Take the opportunity to attack us from other directions!"

Just at this time.

Chao Yuan, the commander of the outpost, rushed in.

"Governor, helicopters have been spotted in the north and west of the outpost! They seem to know where our outpost is and are specifically bombing our outpost. If we don't stop them, they will blow up all the outposts near the Federation!"

really!

Yuan Zhi thought to himself!

It turns out that the purpose of Oil City is here!

Their northern federal outpost is like their eyes.

The alert range of the Northern Federation can be extended to dozens of kilometers away.

If all their outposts are blown up, it will be difficult for them to understand the surrounding situation.

The artillery attack range in the Northern Federation is limited and cannot hit dozens of kilometers away.

Moreover, the helicopter is too sensitive. Even if the artillery can hit it at such a long distance, the probability of hitting it is extremely low.

There is only one solution to this problem, and that is to send helicopters to fight them in the air.

Thinking of this, Yuan Zhi threw away the towel and said to Chaoyuan:

"Go and notify Han Li and ask him to send two helicopters to immediately intercept the helicopters in Oil City."

"I remember that Sima Dong still has two helicopters in his hands. Now follow Han Li's command! Let them pass quickly!"

"In addition, let Wang An from the patrol team go out with the patrol team and cooperate with Han Li and others to attack on the ground."

Yuan Zhi issued several orders without hesitation.

Upon hearing this, Chaoyuan nodded quickly and said: "I understand, I'll inform you right away!"

Leave in a hurry.

....

at the same time.

It is about 20 kilometers away from the northern federal fence.

Whizzing!

Boom!

A guard tower was hit by two rockets.

Rumble!

Before the people on the guard tower could react, the tower collapsed and buried them, crushing them to death.

Along the way, they bombed the sentry towers they saw. This was the third sentry tower they bombed.

Free and free, the Northern Federation has no power to fight back.

Yang Tianlong in the helicopter shouted: "It's great! The map of the Northern Federation drawn by this minister is really useful, the sentry towers are marked so clearly!"

Lao Bi's expression was as usual, and he was not happy about blowing up several northern federal sentry towers. He always remembered his mission, covering the third uncle and the others' infiltration, and trying to make as much noise as possible here.

As long as they make more noise here, the possibility of Third Uncle and the others being discovered is lower.

They wantonly bombed every sentry tower they could see in the northern part of the Northern Federation.

Air versus ground already has a huge advantage.

What's more, these sentry towers deployed by the Northern Federation are not equipped with anti-aircraft guns or anti-aircraft machine guns. With automatic rifles alone, it is difficult to hit helicopters at an altitude of one thousand meters.

They also don't get close to the Northern Federation because they know that there are anti-aircraft guns in the Northern Federation and they will be shot down if they get too close.

Just keep bombing within a range of about ten to twenty kilometers from the Northern Federation!

Just as they were bombing the fifth guard tower, Lao Bi suddenly saw a helicopter flying from the Northern Federation in the distance.

So he immediately raised the helicopter, quickly changed its direction, and flew rapidly to the north.

Han Li, who was following behind and piloting the helicopter himself, looked at the escaping Oil City helicopter with a hint of viciousness in his eyes.

Run away!

Let me see where you can run!

So he drove the helicopter and quickly pursued it.

He didn't believe it anymore, he couldn't catch up with these people from Oil City!

The helicopter configurations of both parties are similar, but the firepower configuration of the helicopters is different.

This chapter is not over yet, please click on the next page to continue reading! The firepower configuration of the Da Zhangshu Base is obviously better than that of the Northern Federation, but not much better.

There are also weapons experts in the Northern Federation, who have installed rapid-fire machine guns and rockets on helicopters.

When Lao Bi saw the helicopter chasing after him, instead of being frightened, he was very happy.

Chase me, chase me quickly, I'm afraid you won't catch me.

....

The other side.

After receiving the news from Zhu Xiao and others, the third uncle did not choose a place to stop.

Instead, it accelerated its speed and maintained a low-altitude flying attitude.

When Third Uncle and the others explored the Northern Federation before, they had already figured out most of the sentry towers around the Northern Federation, especially the road they were flying over at this time.

In addition, they had found a suitable location for their helicopter a few days ago.

Having stepped through the point in advance, as long as they flew over without being discovered, their mission would have been more than half completed.

Twenty minutes later.

They finally arrived at a village about thirty kilometers away southwest of the Northern Federation.

They had researched the area and found that there were no sentry towers for several kilometers around, so they chose this place.

The places where the Northern Federation has the most guard towers are in the southeast and due south directions.

The southwest happens to be a relatively safe route.

This village has long been abandoned, with tall and short houses scattered in a scattered pattern.
