Under Li Yu's influence, the third uncle always regarded human life as the first consideration.

Moreover, even if the three drones are damaged, as long as they can accomplish this big thing, it will be worth it!

After listening to what Third Uncle said, everyone had a good idea of ​​tonight's battle plan.

First, Ant, Jackal and Uncle San controlled the drone, bypassing the sentry tower of the Northern Federation and flying to the outer wall of the Northern Federation.

When they were about to arrive, Lao Luo started heavy artillery bombardment to cover the actions of Uncle San and others.

Then Ant and Jackal controlled the drone to fly to the wall of the Northern Federation and dropped bombs on top of the wall. The fundamental purpose was to cover Uncle San's control of the drone to reach the wall.

The fundamental purpose of the two layers of protection is to safely allow Uncle San to control the drone to reach the wall of the Northern Federation.

Once the third uncle controlled the drone to reach the northern federal wall, he immediately started to self-destruct.

Then they quickly boarded the helicopter, retreated immediately, and returned to Jinggui Mountain to join Li Yu and the others.

The sun sets and the night comes.

But this is not the best time for them to take action. They have to wait until the Northern Federation is most relaxed before taking action.

Time passed minute by minute.

The third uncle took out the dry food that was warmed by his body from his arms, took a bite of the bread and chewed it slowly. After taking a sip of water, he glanced at his watch.

It's eight o'clock in the evening, four hours before they start taking action.

Everyone was so excited that they couldn't sleep. They opened their eyes wide and looked at the time from time to time.

Suddenly, the third uncle heard Lao Qin's voice coming from the intercom.

"Captain, there are two zombies approaching."

Lao Qin never left the helicopter, and he acted as a guard outside.

"Got it," said the third uncle.

Then he said to Wu Jianguo and Ant: "You two put on your night vision goggles and go out to deal with those two zombies."

"Okay." The two said nothing nonsense, put on night vision goggles, and walked downstairs with guns on their backs.

The two wore night vision goggles and did not turn on the lights.

Although there are no Northern Federation sentry towers around here, for safety reasons, they did not turn on the lights after dark and relied on night vision goggles to see the surrounding situation clearly.

Went downstairs.

They saw the helicopter parked outside, and Lao Qin pointed to them in the direction of the end of the road to the east, indicating that the two zombies were there.

The two of them looked up and saw the two zombies, and each tacitly chose the zombie in their own direction.

He slowly pulled out the dagger from his thigh and walked quickly.

Roar!

Phew!

The two zombies were halfway through their roar when their skills were interrupted by a dagger, causing them to belch.

After piercing the zombie's head with a dagger, Ant and Wu Jianguo lifted the zombie's body, slowly lowered it to the ground, and then pulled it to the ruins of a nearby building.

Return to Third Uncle.

"Done?" asked the third uncle.

"Yeah." Ant and Wu Jianguo nodded, as if they had just done something extremely ordinary, as simple as going downstairs and taking a pee.

The third uncle said no more, hugged his shoulders, closed his eyes and rested.

And under his butt is the silver box that Li Yu gave him.

Li Yu brought four potions this time, two type II and two type III. Except for the one he used in Oil City, he still has three.

In order to ensure that this operation could be completed, Li Yu gave all three potions to his third uncle.

Even if the drone controlled by Uncle San is shot down by the people on the wall before it reaches the wall, they still have a second chance.

However, they need to move their position on the second chance, which will involve certain risks...

Time flew by into the early hours of the morning.

On the northern federal fence, the guards yawned and walked out of the guard tower.

He said to the person on duty outside: "The time is up, it's my turn."

The person who was originally standing outside looked at the time and couldn't help but cursed: "Every time you come here, you are five minutes late, you damn..."

....

"Act!" Third Uncle looked at the time and said to everyone.

Everyone took their places.

The third uncle, Ant, and Jackal came to the roof of the building holding the drone.

This chapter is not over yet, please click on the next page to continue reading! Wu Jianguo followed, alert to the surrounding situation.

Beep.

The third uncle turned on the drone and took out a tube of medicine from the silver box.

After careful inspection, it was confirmed that it was a type III zombie attracting agent, and then the protective sheath on the outside of the agent was taken out and stuck in a snap ring specially installed on the drone.

The drone is equipped with a self-exploding bomb. Once it hits the northern federal fence, it will explode immediately.

Wuwuwu——

The three people controlled the drone and took off quickly, extremely flexibly.

They did not fly at low altitude, but flew to an altitude of more than 300 meters, and then flew in the direction of the Northern Federation.

The drone controlled by Ant and Jackal flew in front, and the drone controlled by Uncle San, which carried a zombie attracting agent, followed behind, about a few hundred meters apart.

The drone they used was DJ's FPV model, with a flying speed of 150 kilometers per hour and a maximum flying altitude of two thousand meters.

The distance from Uncle San and the others to the Northern Federation is only thirty kilometers, and they can fly there in 12 minutes.

Along the way, they avoided the watchtowers.

In the dark night, the drone has no light, just like an elf in the dark.

Ordinary infrared cameras emit infrared light when working at night, but the infrared camera installed on the drone they controlled did not emit red light.

This reduces the possibility of the drone not being detected.

Wuwuwu——

The drone was flying at high altitude, and Uncle San and the others were observing the situation below through infrared cameras.

The Northern Federation is so big that you can see the tall walls of the Northern Federation even from a distance of more than ten kilometers.

The lights on the wall illuminate the interior and exterior of the Northern Federation.

There is also a light in the inner city of the Northern Federation, which looks like a strong flame in the dark night, and is extremely conspicuous.

Ten minutes passed.

The Northern Federation is right in front of us.

The third uncle concentrated and said to Wu Jianguo: "Get ready for heavy artillery bombardment!"

Wu Jianguo quickly picked up the walkie-talkie and contacted Lao Luo downstairs: "Lao Luo, heavy artillery bombing!"

Lao Luo, who had been waiting on the ground outside for a long time, finally received the order.

So he said to Xiao Ding, Xiao Liu and others: "Fire!"

A cannonball flew out of the barrel, flew for more than ten seconds, and hit a guard tower on the southwest wall of the Northern Federation.

A precise batch!

This is due to the fact that the location parameters given by Uncle San and others were accurate enough, coupled with Lao Luo and others' repeated proofreading, it was a success the first time!

Beep-beep-

A siren sounded from the northern federal fence.

"Enemy! Attack!"

A guard climbed up from the ground, sounded the alarm, and shouted around.

About twenty meters behind him, the sentry tower collapsed. The sentry tower collapsed, and a pit of five or six meters appeared.

But the wall was not penetrated. After all, the wall in the north was very thick, and one shot would definitely not be able to penetrate it.

....
Chapter completed!
