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

Looking at the green tree not far away, the trunk is wrapped with a layer of hemp rope, which is used to protect the big tree from freezing to death.

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

Li Yu's brain was running rapidly.

According to Qingyuan's inference, the heavy fog is not just in a certain area, but covers the whole world, so places such as Oil City will be affected.

First, here is the Da Zhangshu Base.

The task of collecting supplies from a long distance needs to be suspended, otherwise those who have performed the task may never come back.

Just like Chen Delong's group, dozens of people went out. If Chen Delong and the four hadn't found a wooden house in the mountains, they wouldn't have been able to survive the heavy rain.

In addition, plans to expand the base will also have to be postponed.

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

The height of the wall is more than thirty to forty meters. In such a remote mountain forest, coupled with the existence of the mobile gate knife, it should be possible to ensure that the zombie wave cannot rush in.

The base has survived so many zombie waves and has a strong ability to withstand risks to this day.

Over there in Oil City.

As the temperature rises during this period, recent temperatures have been above freezing.

The trading market needs to be temporarily suspended.

In addition, food supplies must be delivered as soon as possible. The fog lasted for a long time, and it would be troublesome if the oil city ran out of food.

A simple version of the mobile knife has also been installed in Petroleum City. With gasoline combustion protection, it should be able to survive in foggy weather.

Then only the northern federal garrison is left.

There is no mobile knife installed there, so I don't know if it can survive the zombie wave.

Sudden.

Li Yu narrowed his eyes. He had been to the skies above the Northern Federation. The outer city walls of the Northern Federation were even higher than the Great Zhangshu Base.

And they have survived so many zombie waves, so there should be no problem.

But the last time he went to see it, because the Northern Federation did not surrender, they used heavy artillery bombardment and blew a huge hole in the Northern Federation wall.

If this hole had not been filled before the zombie wave, the outer city of the Northern Federation would probably have fallen...

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

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

Thinking of this, Li Yu hesitated.

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

After thinking about it, he suddenly found himself in the Second Outer City.

Looking at the machinery maintenance factory in the distance, Li Yu suddenly remembered one thing. Some experts from the Northern Federation have not been taken away yet!

Oh shit!

How could I have forgotten this matter?

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

Now that I have thought of it, we must transfer the talents from 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 a cart. On the cart was a huge fuel tank.

"City Lord."

"City Lord."

"City Lord."

After He Bing saw Li Yu, he quickly put down what he was doing and walked over.

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

After Xue Zhihua heard what Li Yu said, he continued what he was doing.

Li Yu looked around and saw Lao Dong and several people gathered around in the distance, seemingly busy assembling.

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

He Bing quickly said: "He was in that helicopter, along with Ding Zhao and Qin Feng."

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

Then he spoke again: "And that Ding Zhao, let him come too."

"good."

Inside the helicopter.

呲呲呲——

Ding Zhao is welding the fuel tank of the helicopter.

"Li Hang, Ding Zhao, the city lord is here, let you pass." 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 together.

....

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

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

"City Lord." Ding Zhao said.

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

"Can these helicopters be modified within 10 days?"

He Bing's eyes widened and he said:

"Didn't the president say there's no rush? Ten helicopters in 10 days? 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 little short... Why are you in such a hurry?"

Li Yu said: "Just tell me if you can do it? Under the premise of ensuring quality."

Li Hang glanced at Ding Zhao, who nodded slightly.

When Li Hang saw Ding Zhao nodding, he said, "You can try it."

Li Yu was relieved when he heard they said yes.

Then he explained: "There are some people from the Northern Federation who need to be transported here. They are experts in various industries from the Northern Territory. They were not brought back last time. Now I want to bring them over as soon as possible."

"At that time, you can also have more manpower here."

He Bing heard this and said with a smile: "This is a good thing!"

Li Hang also nodded and said: "If you want to say that, then we won't be sleepy and we have to get it done as quickly as possible. Brother, you don't know that our machinery maintenance factory is very busy."

"After the senior maintenance engineer Jiu Ge and the few people under him went to Oil City, we were so busy during this period that we split one person into two..."

Li Yu opened his mouth and said:

"When we bring the experts from the Northern Federation here, you will be able to relax a lot."

This chapter is not over yet, please click on the next page to continue reading the exciting content! "Then there is another thing. I want to transfer a few people from you to go to the north."

Li Hang frowned and asked: "Time is already very tight, and we still need to mobilize personnel. I'm afraid..."

Li Yu explained: "Those talent experts in the north have to go through interviews. We need to send some knowledgeable people to interview them. Otherwise, what will happen if those fake rotten fish and shrimps get in?"

"Let's do this. Let Lao Dong, Zhang Shuqi, Kong Shuang, and biochemistry and physics each send a professor-level person to interview those in the north."

After Li Hang heard these names, he breathed a sigh of relief.

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

The mechanical maintenance factory only transferred an old director, which had little impact on their progress in transforming helicopters.

So Li Hang said: "Okay, then should I contact Bai Jie?"

Li Yu nodded and said:

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

"Then send it over before the Chinese New Year. There are still eight days."

"At that time, I can deliver the New Year's goods there, and then I won't have to empty my plane when I come back. I can bring people back."

Li Hang calculated the time, eight days.

Probably only three to four helicopters can be modified, plus the one at the base that has already been modified and is about to be modified.

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 to contact the second uncle and ask where he is.

After learning that his second uncle was still in the First Outer City, Li Yu hurried over.

A few minutes later.
