Although the location of the heavy artillery bombardment was also southwest of the northern federal outer wall, it was still a hundred meters away from the helicopter controlled by Uncle San and the others.

Unknown village.

One shot ends.

Lao Luo quickly said: "Reload."

"Xiao Ding, adjust the parameters!"

....

The other side.

The third uncle's eyes turned cold and he said to the jackals and ants: "Start bombing!"

After the two heard the order, they immediately flew down.

Whizzing.

The bomb was ejected onto the wall.

"What just happened? Enemy attack?"

"What do you see in the sky?"

"No, get out of here!"

Boom! The bomb exploded before falling on the wall.

The two guards closest to the bomb were mercilessly torn apart in an instant.

A pool of blood and mud.

At the same time, under the cover of Jackal and Wolf, the third uncle quickly rushed towards the northern federal wall.

Lower the height, then lower again.

There was another sound of heavy artillery bombardment.

The drone controlled by the third uncle crashed into the northern federal wall.

It's about thirty meters high on the southwest wall of the Northern Federation.

Boom!

The moment the drone touched the wall, it exploded.

The bottle of type III zombie attracting potion that was stuck in front of the drone cracked instantly.

Bah!

The medicine exploded and was blown everywhere.

Most of them splashed onto the outer wall, and a small part fell to the ground outside the Northern Federation.

The self-destruction of this drone did not have much power. It only blew a gap of less than one meter in the middle of the wall.

The adhesive of the medicine is very strong. After the medicine in the glass bottle flew out, it stuck to the wall, which was extremely strong.

Either peel off the small piece of wall that is stuck on it, otherwise the agent will be difficult to remove.

Bits and pieces of potion splashed onto the wall.

Boom, boom!

The jackal and the ant continuously controlled the drone to drop bombs on the wall.

boom!

A bullet hit Jackal's drone, and the drone fell slowly outside the wall.

It fell from a height of hundreds of meters and the drone shattered into pieces.

"You two, go and see if my medicine has been spilled on the wall!" After the third uncle's drone exploded, he immediately said to the ants and jackals.

Jackal said helplessly: "The drone I controlled crashed."

With a nervous look on his face, Ant controlled the drone to avoid the bullets and landed down to the location where Uncle San's drone exploded.

The third uncle and others quickly moved over to look at the drone camera.

When they saw the black chemicals stained on the wall, they breathed a sigh of relief.

Just the next second.

A bullet hit the drone controlled by Ant.

At this point, all three drones have crashed.

"Let's see if there are any other drones. Damn it, I'm almost miserable." A guard on the wall said.

At the same time, the inner city of the Northern Federation.

Yuan Zhi hurriedly walked out in pajamas.

"Where did the gunfire come from?"

The guard outside replied: "It's coming from the southwest. Captain Han Li just came over and was stopped by me."

"Why are you stopping him? Bastard!" Yuan Zhi said angrily.

The guard said with some grievance: "Governor, didn't you say that you have a headache recently and your sleep quality is poor? You asked me not to let anyone disturb your sleep."

"That shouldn't be the case...the military situation is urgent...you...forget it." Yuan Zhi was shaking with anger and pointed at the guard with his finger.

In the end, he put down his hand. There was no need to settle accounts with him at this time. We should first figure out what the situation was.

He ran to the office, got the walkie-talkie, and asked Yin Xi about the situation there.

"Yin Xi, what's going on with the sound of shelling?"

Yin Xi looked at the collapsed wall not far away and said with tears in his eyes: "Maybe it was people from Oil City. They bombed our wall with artillery."

"Artillery bombing? Don't we have a sentry tower? Didn't the sentry tower detect them?" Yuan Zhi was furious when he heard this.

Yin Xi said helplessly:

"I don't know either. People from Oil City bombed four times and then stopped. Now I've asked everyone to hide. I don't know when people from Oil City will bomb again!"

Yuan Zhi's brain was running rapidly, and with a flash of inspiration, he quickly said: "Let Han Li lead the helicopter brigade to the firing site to counterattack!"

"He has already set off..." Yin Xi said while looking at the helicopter flying into the sky.

"Okay! This guy Han Li is finally reliable."

Yuan Zhi thought for a moment and then continued: "Can you find out where the artillery fire is in Oil City? Let Liu Wei's artillery team bomb back..."

Yin Xi looked at Liu Wei who was standing next to him.

Handed the walkie-talkie to Liu Wei.

"Governor." Liu Wei said.

"Huh? Liu Wei? Why are you still standing there? Fight back!"

Liu Wei said with some bitterness in his heart:

"The measured distance is more than thirty kilometers, which is beyond the range of the artillery we have. Moreover, I looked at the power of the artillery and inferred that the oil city may be using extremely powerful heavy artillery!"

"You said we don't have any?" Yuan Zhi exclaimed.

Liu Wei quickly explained: "If you are talking about whether there is such a thing as heavy artillery, yes, we do not.

Our farthest artillery attack distance is only 20 kilometers. In terms of range, it can reach more than 30 kilometers, but beyond 20 kilometers, it is impossible to achieve accuracy.

The effective range of twenty kilometers is already very far, who would have thought that they actually have such a thing as a heavy artillery."

When Yuan Zhi heard this, he felt a sense of absurdity.

He had always felt that no matter what the Northern Federation said, no matter whether Oil City had the ability to control zombies, he would never lose when it came to weapons and equipment.

However, they don't have this heavy artillery.

He was inexplicably frightened.

How many mysterious weapons are there in this oil city?

Facing a powerful enemy is not scary. What is scary is not being able to see through your enemy.

Ma Song hurried to Yuan Zhi's office.

Seeing Yuan Zhi with a frightened look on his face, no lights were turned on in the room.

The moonlight outside the window shone on Yuan Zhi's face. Ma Song saw Yuan Zhi's side face from the angle of the door, and saw oldness and fatigue on his face.

"Governor." Ma Song walked over and whispered.

Yuan Zhi calmed down his emotions and quickly switched his expression to a calm mode.

"Turn on the light." He said to the guard who was following him.

The guard quickly turned on the office lights.

"Governor, when people from Oil City used helicopters to bomb us during the day, it might just be a cover-up." Ma Song said softly.
