Big camphor tree base.

Li Yu learned from his third uncle that they had safely retreated from the Northern Federation and were now flying a helicopter back to Oil City.

After receiving the news from his third uncle, Li Yu felt relieved.

Next, you just need to let the bullet fly for a while.

Waiting for the fog to arrive in the north, by that time, tens of millions of zombies, blessed by the foggy weather, will surge in and pile up to climb over the city wall.

People in the northern border can basically be sentenced to death.

Even though he didn't see the scene of TC, Li Yu's mood was ups and downs.

Clang, Clang, Clang——

At this moment, there was a sharp and urgent sound outside.

At this time, the mobile gate of Da Zhangshu Base was opened.

It was raining lightly all the time in the base.

The liquid nitrogen factory works overtime, operates at full capacity, and continuously produces liquid nitrogen. Then, the used-up liquid nitrogen tanks are filled with liquid nitrogen, and then transported to the inner and outer cities for spraying.

Li Yu came out of the duty room.

Under searchlights.

The bustling zombies were as densely packed as ants.

They are constantly stacked in an area, but they have not yet reached the position where they touch the moving blade.

Li Yu frowned slightly when he saw this scene, and quickly picked up the intercom and asked: "Uncle, this zombie wave can only stack up to two or three meters, which is far from the point where you need to use a mobile knife. Why did you turn it on so early?"

ah?'

The uncle at the back was also observing the zombie wave, but his attention was more focused on moving the knife.

After hearing Li Yu's inquiry, he quickly picked up the walkie-talkie and replied:

"I know. I'm checking the operating status of the mobile blade in advance to avoid trouble when it breaks down when I use it."

As he said that, the speed of the moving blade on the bottom layer slowly decreased.

Immediately afterwards, the moving knife on the second floor began to rotate slowly.

After seeing this scene in the duty room at the front door, Li Yu replied:

"okay, I get it."

The other side.

In the fourth outer city.

Li Tie led Lai Dongsheng and others to investigate here, and finally took away five or six experts and talents from the north, as well as seven or eight collaborators.

These people were all detained in interrogation rooms in the inner city.

So far, no one who has been caught in the interrogation room in the inner city has come out alive.

These people were caught in the interrogation room, which meant death.

Cannon also escorted Goatee and the other three people to the interrogation room.

Centralized interrogation.

Li Yu's attitude towards this matter is to investigate thoroughly!

After the interrogation, the personnel involved in this matter did not need to be severely punished, but were directly killed.

The accident of breaking into the inner city gave Li Yu a great sense of threat and made him extremely angry.

Otherwise, they would not have massacred the Northern Territory directly in a fit of rage.

Heavy fog hits the city.

He wants to tell everyone at this critical moment that if you dare to commit a crime at this time, there will be only one way out if you are caught: death!

Although liquid nitrogen has no smell, if it is sprayed too much, the oxygen content in the air will be reduced, making people feel slightly uncomfortable.

But there is nothing that can be done. To ensure clear vision inside and outside the base, liquid nitrogen must be continuously sprayed.

The raw material for making liquid nitrogen is air, and the most consumed energy is electricity.

However, the Da Zhangshu base is currently extremely rich in electricity.

The zombie generator generates a steady stream of electricity for use in supplying the base.

Thick fog filled the air.

The Da Zhangshu base has been sprayed with liquid nitrogen, but it can still have a certain field of vision to resist the incoming zombies.

But for most of the survivor organizations in the apocalypse, it is an extremely difficult test.

Northern Commonwealth.

Yuan Zhi did not enter the garrison base.

Because he is not sure if there are other explosives buried in the Da Zhangshu base here.

He had just sent Yuan Li, Tian Yunxiao, Fan Haiyang and others to search in case there were bombs buried by them at Da Zhangshu Base.

Seeing He Liangwei and others carrying out the bloody Yuan Youzhi, Yuan Zhi looked at He Liangwei.

Facing Yuan Zhi's eyes, He Liangwei sighed in his heart and shook his head.

When Yuan Youzhi was dragged out from the ruins, he was no longer breathing.

Yuan Zhi saw him shaking his head, and his anger became even stronger.

"Da Zhangshu Base! You and I have a sworn hatred!" Yuan Zhi said each word through gritted teeth.

But there was a hint of helplessness in their hearts. The Da Zhangshu Base could control zombies, and this alone was enough to give them a headache.

Yuan Li and others searched the garrison base for a long time, but did not find the secretly buried time bomb.

On the contrary, they found a large amount of grain, as well as the New Year's goods previously distributed by the Da Zhangshu base.

Yuan Li looked at the food in front of him and said to the excited Tian Yunxiao:

"I'm so excited. We gave them these grains a while ago. Now they just return to their original owners."

Tian Yunxiao's smile faltered, and he said with some confusion:

"Brother Li, why don't the people at their Da Zhangshu base take away the food? This is too abnormal. Are they so rich that they don't even care about this food?"

Yuan Li mocked him and said: "Don't you like hugging the thighs of Da Zhangshu Base? Why, now you open and shut your mouth as soon as you leave..."

"oops!"

Tian Yunxiao sighed helplessly and said:

"I told you that you don't understand. I broke into the enemy for my cousin. You don't know how aggrieved I felt. But for the benefit of our northern border as a whole, I would rather bear this misunderstanding. However, I didn't

To think that you also misunderstood me, alas..."

As he spoke, he put on a very sad expression.

Yuan Li curled his lips and said nothing more.

However, the new year's goods they found during the search did make them very happy.

Originally, when the garrison at Da Zhangshu Base distributed the New Year's goods, they were greedy in the distance. Unexpectedly, so many people from Da Zhangshu Base stayed behind.

Cheaper them!

This caused the searchers to rob each other, and after each received their portion, they stuffed it into their own pockets.

Tian Yunxiao, Fan Haiyang and others did not stop this scene and tacitly agreed not to report it.

If you want a horse to run, you have to give it some grass.

Otherwise, who will work hard for you?

They ran in to search for bombs and took a lot of risks. Since they took such a big risk, they always had to be rewarded.

They can't touch the grain in that warehouse, but the scattered New Year's goods can be used as their harvest.

In the process of searching.

Tian Yunxiao looked at the pot of green plants on the table. The pot of green plants was well taken care of, so he walked over and picked up the pot of green plants.

He wants to put this pot of green plants in his room to add a touch of greenery.

But what he didn't know was that this pot of green plants was the same pot where the ants poured the zombie attracting potion.

.....

A few hours later.

sunset.

On the outer wall of the Northern Federation, Yin Xi had a smile on his lips.

All the Da Zhangshu bases retreated, and the invisible pressure disappeared instantly.
