Eight o'clock in the morning the next day.

Big camphor tree base.

Li Yu took Song Min and others to the Fourth Outer City. More than an hour ago, Song Min had someone deliver breakfast to Mr. Hu and others.

Perhaps Mr. Hu didn't sleep well last night because he was worried.

But last night when he was lying in bed, he couldn't hear the roars of the zombies outside at all. It was so quiet, and even the moonlight shone through the window in the room, giving him an inexplicable sense of peace of mind.

The buffer city is very large and isolates ordinary zombies from outside.

The distance from the buffer city to the outer city is enough to eliminate the movement of zombies outside the buffer city.

"Master Hu, City Master Li and the others are here." A member of the escort team saw Li Yu and others walking in the distance at the door, and quickly ran back to the room to inform Master Hu.

After hearing this, Mr. Hu looked at Tang Ji and the others, "Help me into the wheelchair."

Tang Ji and the other two immediately went over, one of them pushed the wheelchair over, while Tang Ji picked up Master Hu and carried him to the wheelchair.

Due to illness, Mr. Hu's weight dropped sharply from 145 kilograms to less than 100 kilograms.

Tang Ji is very easy to hold.

When Li Yu, Song Min and others entered the room, Master Hu was already firmly in the wheelchair.

"City Lord Li, good morning."

"Master Hu, how did you sleep last night?" Li Yu asked with a smile.

“It’s good, it’s very quiet here.”

Li Yu glanced at Tang Ji, then looked at Master Hu and said:

"I was short of time yesterday, so I only took you to see the Second Outer City. Now I'm going to take you to our wall so that you can have a more comprehensive view."

Master Hu's eyes lit up when he heard this, "Okay."

He was actually quite curious when he saw the mobile gate blades at the Da Zhangshu Base yesterday, but since he couldn't see clearly from the ground, if he could go up the wall and look down, he should be able to see it more clearly.

"Please." Li Yu extended a gesture of invitation.

Before Master Hu could give Tang Ji a signal, Tang Ji pushed Master Hu outside.

After walking out of the room, Li Yu and Master Hu walked side by side and gave a brief introduction to the situation in the fourth outer city.

Li Yu didn't bring many people here this time. The only ones accompanying him were Song Min and Li Tiesan.

So Master Hu asked all the members of the escort team to stay here, and only asked Tang Ji and Dr. Zhang to go with them.

"There is a Taoist temple behind here. If I have time later, I can take you to see it."

Master Hu looked at the numerous greenhouses in the Fourth Outer City and asked:

"How many greenhouses are there in the Fourth Outer City? I came all the way here and there were greenhouses all around."

"There are 120 greenhouses, each of which is 2 acres in size."

After hearing this number and size, Mr. Hu and Dr. Tang Jizhang's breathing became rapid.

They went to see a greenhouse yesterday. The greenhouse was seven or eight meters high. Some greenhouses were stacked with shelves. The two-acre space had three floors, giving the effect of an area of ​​six acres.

This greenhouse alone in the Fourth Outer City has hundreds of acres of planting area.

Moreover, the space utilization rate in the greenhouse is extremely high, and it can even achieve the effect of being planted flat on the ground for thousands of acres.

The most important thing is that the temperature, water source, and light can be controlled in the greenhouse, and planting can be done all year round.

Mr. Hu secretly thought: No wonder the Da Zhangshu base always seems to have no shortage of food. With such a stable and large supply of food, there is no need to worry about food problems at all.

It’s just...it’s easy to solve the water sources needed for so many greenhouses, but how to solve the problem of the massive amount of electricity required?

The entire Da Zhangshu Base is of such a large scale that the power consumption must be staggering.

I didn't see their power plant yesterday. If it relies solely on solar power, it will definitely not be able to meet the power consumption needs of such a large base.

Later, Li Yu took Mr. Hu and the others to the bottom of the outer city wall and took the elevator up to the outer city wall.

The outer city walls are 58 meters high, and you can see in the bulletproof glass of the elevator that they are getting further and further away from the ground.

The wall of Southern Paradise is only half as high as here. Standing on the fifty-eight-meter wall, it gives Tiger Ye Tang Ji and the others a completely different feeling than in Southern Paradise.

Mr. Hu's wheelchair was raised so that he could see the surroundings beyond the walls of the fence.

After Master Hu and the others climbed onto the wall, they began to look at the situation above.

The width of the outer city wall reaches 7.5 meters, even allowing two cars to drive side by side.

wide.

There is a fixed ultraviolet lamp installed at regular intervals above. Once night comes, the ultraviolet lamp can be pushed out and turned on to shine outside the wall.

On the side closer to the city, there is a hanging street lamp every five meters on the wall.

These street light circuits are hidden in the walls.

Along the way, every fifty meters, there is a protruding wall, covering an area of ​​about twenty square meters.

Here are placed anti-aircraft machine guns, anti-aircraft guns, mortars and other heavy weapons.

These protruding walls can form a perfect triangular fire network with the parallel walls.

And if you look at it from a higher perspective, you will find that there are dozens of such concentrated firepower points on the inner and outer walls of the Dazhangshu Base.

Such firepower points form an aerial net, which can not only clear out threats from the ground, but also solve threats in the air.

When Master Hu saw these brutal weapons, his withered hands squeezed the armrests of the wheelchair slightly.

So damn cruel!

The firepower of this Da Zhangshu base is too brutal!

Yesterday, we saw those heavy artillery pieces with terrifyingly large barrels in the Second Outer City. They should be ground defense points, and what we see now should be the wall defense network.

"City Lord."

"City Lord."

From time to time, several patrol officers riding yellow electric donkeys and carrying automatic rifles passed by and stopped to say hello to Li Yu.

"Yeah." Li Yu nodded in response to every combatant who stopped.

"City Lord Li, do you basically use a small electric donkey to ride? It's quite unique." Mr. Hu looked at the patrol members walking away and asked Li Yu in admiration.

He is well aware of the advantages of this small electric donkey: it is convenient, small in size, and can be lifted by one person.

But where are all the batteries and electricity coming from?

Faced with this question, Li Yu had no choice but to answer:

"There is nothing we can do about it. The base area is too big. If we just rely on running, the speed will be too slow."

"Actually, it's not just the wall. Our entire Da Zhangshu Base has implemented small electric donkeys for transportation. We have set up 2 charging stations and 30 charging piles on the wall. We have also set up 20 charging stations in the inner and outer cities, and more than 300 charging stations.

A charging station.

There are actually about a dozen charging stations and more than 200 charging piles in the buffer city."

Master Hu swallowed his saliva and was even more surprised when he heard that there were six hundred charging stations alone.

"Can these small electric donkeys be used at will? How many small electric donkeys are there in total?"

Li Yu smiled and nodded:

"Of course, some of them, like the pre-apocalyptic bicycle sharing and electric vehicle sharing models, are also for the convenience of everyone."

"As for e-mules, a total of two thousand e-mules have been invested, which can basically meet the travel needs of our base."

Mr. Hu heard the implication: Li Yu was talking about investment, not ownership.

The investment means that the current population of Da Zhangshu Base only needs so many e-mules, not that they only have 2,000 e-mules.

From yesterday to today, Master Hu, who had been shocked countless times, once again expressed emotion.

"Sometimes I doubt that we live in two worlds, alas..."

The difference is huge.

The Southern Paradise led by me has been fighting hunger and zombies for the past five or six years.

All I think about all day long is how to accumulate more food, and I am always worried about food shortages.

Thinking about how they would face the terrifying zombie wave if a heavy rain came.

However, looking at the Da Zhangshu Base, I am already thinking about how to improve convenience and run in a more comfortable direction.

Moreover, I thought that the firepower over there in Oil City was already very strong.

The fire defense at Da Zhangshu Base is even more ridiculously strong!

The past two days have really shocked Mr. Hu. He even felt that Da Zhangshu Base was willing to take them to play in the Southern Paradise, let them do trading fairs together, and even gave them a portion of the profits.

I really admire them!

Mr. Hu couldn't help but feel a little nervous. He didn't know if City Lord Li could see their southern paradise.
