"Why is there smoke over there? Is it on fire?" Master Luo looked at the thick smoke billowing behind the limestone mine.

Lao Luo raised his head and looked in that direction, and sure enough, there was white smoke coming out.

"The city lord said they are back and should be fine."

While they were talking, several trucks appeared on the right side of the limestone mine and were heading towards them.

Lao Luo quickly stood up and jumped out of the car.

Went out of the car to welcome the city lord and his companions back.

Crunch!

The vehicle stopped, and Lao Luo and others gathered around it.

"City Lord."

"City Lord."

"City Lord, what's going on over there in the cave? What should we do now?"

After hearing what Lao Luo said, Li Yu turned his head and looked at the limestone mines nearby.

"The cave has been sealed by our explosion."

"you...."

"Let's all retreat. Don't mine in this mine. Find a limestone mine instead."

There is an underground river in that underground cave. They don't know where the underground river will lead. Leaving here is the best choice.

Hearing that the city lord wanted to leave here, Master Luo's face lit up.

Once a mining site is determined, the collaborators are the ones who need to be stationed here permanently, and people from outside cities will rarely come.

So many of his men died here, and there were so many zombies in the cave not far from them. It makes me sick just thinking about it.

Master Luo was eager to leave here.

"Pack up and go back to base."

Li Yu got out of the car and walked towards the helicopter.

Lao Bi and others behind him lifted up the tightly tied mutant zombies and carried them onto the helicopter.

This trip was not particularly smooth, because I didn’t see the underground river, and I didn’t know why there were so many mutant zombies in it.

However, at least the underground cave was sealed.

Li Yu and others boarded the helicopter, leaving Yu Wei, Master Luo and others to drive the electric trucks back to the headquarters base.

Buzz buzz——

The helicopter flew into the sky, and Li Yu looked at the raging fire burning below.

The flames have spread to the woods, and even the nearby mountains and forests have been ignited.

Take your eyes back, close your eyes and rest your mind.

It's the end of the world, who cares about burning mountains?

What's more, if all these weeds and trees are burned, the place for zombies to hide will be smaller.

.....

Ten minutes later.

The helicopter landed in the city outside the Da Zhangshu base.

Bai Jie asked Lao Bi and the others to help carry the mutant zombies they brought back to the scientific research institute.

She must seize the time to study these mutant zombies. According to Yu Wei and others, these mutant zombies are stronger than before.

By conducting slice studies, we can find out whether the amount of virus contained in these zombies has increased.

If it increases, it will once again verify the previous guess:

The more viruses an individual zombie carries, the more powerful it is.

This is just the change of zombies found in the cave. It may be special and not representative.

Later, we need to capture mutant zombies from other places and study them to confirm that the zombies are indeed getting stronger.

.......

........

Not long after Li Yu and others returned to the base, several more helicopters took off and flew north.

Lao Zhou personally led the team and sent the ultraviolet lamps recently produced in the base to Oil City and the North.

In addition, there are also some agricultural-related technical experts who will be sent to the north together.

Agricultural planting in the north has been planned for a long time.

As early as half a year ago, after the Northern Territory was slaughtered, Li Yu had finalized the decision with his second uncle and the others.

Even the raw materials, PVC solar panel materials and equipment for building the solar greenhouse have been prepared.

Work started for a while, but then a thunderstorm interrupted their plans.

I have no choice but to put it on hold until now.

On the helicopter, Lao Zhou sat in the co-pilot and looked at the electronic map.

"Dingshan, I haven't been to that oil city yet. What does it look like?"

Dingshan drives a helicopter and wears black sunglasses.

The corners of his mouth turned up slightly, "How should I put it? I don't know how to describe it. You'll know when you go there."

"Brother Zhou, did you follow Brother Qin before?"

Lao Zhou smiled and said:

"Well, after I was discharged from the army, I went to a lathe factory. I didn't know that Lao Qin was from that team before."

Dingshan said with emotion: "Brother Qin and I went to the Northern Territory half a year ago and saw with our own eyes the minister's suppression of those affiliated with the Northern Territory who disobeyed management. It was fierce!"

Lao Zhou and Yourong Yan recalled the time they spent in the lathe factory with Lao Qin, and they felt as if they were in another world.

It's like a long, long time has passed.

But in fact, it has only been more than five years since the end of the world, but it feels like he has experienced it more than ten or twenty years ago.

The helicopter flew towards Oil City according to the established route.

Dingshan has flown this route many times and is very familiar with it.

The two chatted and time passed slowly.

Three and a half hours later, they arrived at Oil City successfully.

Lao Zhou looked down from the sky and saw Nuoda's oil city and trading market, with shock in his eyes.

He originally thought it was just a very small base, but he didn't expect it to be so big!

The trading market covers an area of ​​two thousand acres, which is almost the same area as the inner city of Da Zhangshu Base plus the four outer cities.

However, if the headquarters base and the buffer city are included, it will be more than ten times larger than the trading bazaar.

Lao Zhou has stayed at the headquarters base for a long time and didn't know there was such a large territory outside the base.

And it looked like there were a lot of people inside.

Construction work is being carried out in full swing in the trading market, and the rows of houses are arranged very neatly.

It can be expected that if the construction of the trading market is completed, it should not be too bad.

With this feeling of shock, the helicopter slowly landed in the oil city.

Knowing that someone was coming from the headquarters base, Ju Tianrui took Dongtai and others out to greet them.

"Huh? Lao Zhou, why are you here? I thought it was Captain Li Tie and the others?"

Lao Zhou looked at Ju Tianrui, whom he had not seen for a long time.

"They happened to have something to do, so I came over as a substitute to follow them. You did a good job. You did it very well and created such a large territory without saying a word."

Ju Tianrui had a smile on his face. Indeed, the Oil City has changed a lot during this period.

The trading market was built at an astonishing speed, and the market street has become more and more popular recently.

The trading market started from scratch, and he watched it being built bit by bit.

"These are all results achieved under the leadership of the city lord."

Hearing Ju Tianrui's answer, Lao Zhou teased and said, "You have become so greasy."

"Let's take you for a walk. You haven't eaten yet. I'll take you to the cafeteria to eat... The food here is definitely not as good as the one at the headquarters base. Just eat whatever you want." Ju Tianrui pulled him.

Lao Zhou left the helipad.

After the two exchanged a few words of greeting, the strange feeling of not seeing each other for a long time subsided a lot.
