After coming out of the residential building in the outer city, Li Yu frowned.

Looking at the big tree not far away, the trunk is wrapped with a layer of hemp rope, this is used to protect the big tree so that it will not freeze to death.

There are not many green leaves on the branches, only a few.

Li Yu's brain is running fast.

According to Qingyuan's inference, heavy fog is not just in a certain area, but covers the world, and oil cities and other places will be affected.

First of all, here is the Dazhangshu Base.

The task of collecting materials at a distance needs to be suspended, otherwise these people who have performed the task may never be able to return when they go out.

Just like Chen Delong's group, dozens of people went out. If Chen Delong and the other four found a wooden house in the mountains, they would not have been able to persevere in the heavy rain.

In addition, the plan for expansion of the base must be postponed.

In addition, there is not much to prepare at the Dazhangshu Base.

The height of the wall is more than 30 or 40 meters. In such a remote forest, coupled with the existence of mobile gate knives, it should ensure that the zombie tide cannot rush in.

The base has been firmly steadily in so many zombie waves, and until today it has a strong ability to resist risks.

On the other side of the oil city.

As the temperature rises during this period, the recent temperature is above zero degrees.

The trading market needs to be paused.

In addition, in terms of food and food, it must be sent as soon as possible. The heavy fog lasts for a long time, and it will be troublesome if the oil city cuts off food.

A simple version of mobile brake knives has also been installed in the oil city, which is combined with gasoline combustion protection and should be able to stand firm in heavy fog weather.

Then only the troops of the Northern Federation remain.

There is no mobile brake knife installed there, I wonder if it can stand firm in the zombie tide.

Sudden.

Li Yu narrowed his eyes. He had been over the Northern Federation. The outer wall of the Northern Federation was higher than the Dazhang Tree Base.

Moreover, after so many zombie waves, they have been hardened, so there should be no problem.

However, when he went to see it last time, because the Northern Federation did not surrender at the beginning, they used heavy artillery bombing to blow up a huge hole in the Northern Federation wall.

If this hole was not filled before the zombie tide, it would probably be that the outer city of the Northern Federation would fall...

Most of the population of the Northern Federation is in the outer city. If the outer city falls, the strength of the Northern District will inevitably be greatly damaged.

However, it should not have much impact on the inner city.

Thinking of this, Li Yu hesitated a little.

He was struggling whether to remind the Northern Federation to repair the outer city wall as soon as possible.

As he thought about it, he suddenly found himself in the second outer city.

Looking at the mechanical repair factory in the distance, Li Yu suddenly remembered something. Some experts and talents from the Northern Federation have not taken away yet!

Oh shit!

How did you forget this?

But at that time, I also thought about bringing my own people back first, and then I thought about slowly moving.

Since we have thought of it, we must transfer the talents in the Northern Federation as soon as possible.

Thinking of this, Li Yu walked towards the machinery maintenance factory.

As soon as I walked into the machinery maintenance factory, I saw Xue Zhihua, Lao Zhou and others pushing the cart. There was a huge fuel tank on the cart.

"City Lord."

"City Lord."

"City Lord."

When He Bing saw Li Yu, he quickly put down what he had in his hands and walked over.

Li Yu nodded to everyone, and then said to them: "You guys are busy with yours, don't worry about me."

After hearing Li Yu's words, Xue Zhihua continued what he had.

Li Yu looked around and saw Lao Dong and a few people gathered together in the distance, as if they were busy assembling.

"Where is Li Hang? Isn't he here?" Li Yu asked.

He Bing quickly said, "He is in that helicopter, with Ding Zhao, Qin Feng and others inside."

"Well, let him come out." Li Yu said.

Then he spoke again: "There is that Ding Zhao, let him come together."

"good."

Inside the helicopter.

sir-

Ding Zhao is welding the fuel tank to the helicopter.

"Li Hang, Ding Zhao, the city lord is here, let you go over." He Bing said to the two of them after getting on the helicopter.

"What? My brother is here?" Li Hang was a little surprised when he heard this, and then asked Ding Zhao to put down the welding rod in his hand and go over together.

....

"Brother, why are you here?" Li Hang looked at Li Yu and said after coming.

Li Yu glanced at the unsightly Ding Zhao who was following him.

"City Lord." Ding Zhao said.

Li Yu didn't say nonsense and asked to the three of them:

"Can these helicopters be modified within 10 days?"

He Bing widened his eyes and said:

"Didn't the president say there is no hurry? 10 days, ten helicopters? It's impossible, time is too tight."

Li Yu frowned and continued to ask:

"I'll give you thirteen days and six helicopters, can you modify them?"

Li Hang interrupted, "The time is still a bit short... Why are you so anxious?"

Li Yu said, "You just want to tell me if you can do it, right? Under the premise of ensuring quality."

Li Hang glanced at Ding Zhao, and Ding Zhao nodded slightly.

After seeing Ding Zhao nodding, Li Hang said, "You can try it."

Li Yu was relieved when he heard them say yes.

Then he explained: "Some people in the North Federation want to transport them here. They are experts from all industries in the North. They didn't bring them back last time. Now I want to bring them over as soon as possible."

"You can have more people at that time."

He Bing smiled and said, "This is a good thing!"

Li Hang also nodded and said, "If you say this, we will not be sleepy. We must do it as quickly as possible. Brother, you don't know that our machinery maintenance factory is busy."

"After that senior maintenance master Jiuge and the few people under him went to the Oil City, we were so busy that we broke into two people alone..."

Li Yu said:

"You will be much more relaxed when you bring those experts from the Northern Federation here."

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! "Then there is another thing, I want to draw a few people from you to the North."

Li Hang frowned and asked, "Time is already very tight, and I'm afraid... "

Li Yu explained: "Those talent experts in the North always have to go through an interview. We need to send some knowledgeable people to interview, otherwise what if those fake rotten fish and shrimps are involved in it?"

"Let me do this, let Old Dong, Zhang Shuqi, Kong Shuang, and other major categories of biochemistry and physics send a professor-level person to interview those people in the North at that time."

Li Hang breathed a sigh of relief after hearing these names.

Lao Dong is mainly an expert in electric power, Zhang Shuqi is an expert in physics, and Kong Shuang is an expert in biochemistry.

The machinery maintenance factory only selected an old boss, which had little impact on their progress in transforming the helicopter.

So Li Hang said, "Okay, then do I want to contact Bai Jie?"

Li Yu nodded and said:

"Yes, you go and contact them and tell them as soon as possible, and let them arrange their work tasks in advance. Well... there is no need to wait for you to transform all the helicopters..."

"Then send it before the New Year, there are eight days left."

"At that time, you can just deliver the New Year's goods, and then you don't need to use an empty plane to bring people back."

Li Hang calculated the time, eight days.

It is probably only possible to transform three to four helicopters, plus the base one that has been renovated quickly.

There should be no problem.

So Li Hang nodded and said, "Okay!"

After Li Yu explained all this, he left the machinery maintenance factory.

Pick up the walkie-talkie and contact my second uncle and ask where he is.
