"35 centimeters thick, this is also a courtyard wall, and it is far from the 'city wall'."

At this moment, Lin Yue stood at the gate of his refuge, looking at the cracks in the five-meter-high wall in front of him that had been formed by the smashing, and felt as if he had to upgrade it.

The city wall is not high, first of all, it must be "thick".

Lin Yue still remembers that when he organized a tour to Xijing in high school, he once walked around the city wall there.

The walls of Xijing are ridiculously thick, and at that time, I heard a tour guide with a few tourists say that the bottom is up to 18 meters and the top is up to 14 meters wide! You can easily drive a car.

Lin Yue still remembers that he did see a bicycle on it, which was outrageous.

Looking at him now, he was smashed by a huge hailstorm and broke out huge cracks and ravines, and the dilapidated 35-centimeter-thick "wall" felt a little too cold.

Originally, when he came back from that side just now, he wanted to get all the materials and immediately go to the crude oil mine to build a doomsday bunker, and by the way, use the fence and the means of defense such as a medium-sized electric sentry machine gun or a robot dog to make a solid defense over there.

But I didn't expect that before I could go out, under the prompting of Xiao Meng and other Xiaoice lizards, I saw the wall that could already be described as "tattered" or collapsed, or broken.

Lin Yue checked it a little, and found that the wall that he thought was very strong could basically be thrown away.

The original purpose of the wall was to protect the various structures of the Vault from the mutated creatures and lizardmen from easily approaching the Main Vault.

As the scale of his production increased, various buildings also rose from the ground, and as the requirements for the breadth of the land increased, the walls continued to move outward.

Today, one side of the wall is 220 meters long, and the four sides enclose an area of 48,400 square meters.

In the past, when there were no glass greenhouses, medium-sized farms, large warehouses and food processing plants, this was barely enough, but after these large buildings, the whole space was obviously squeezed and compressed a lot.

Today, this vast space of 50,000 square meters is completely insufficient.

Even without the severe damage caused by the giant hailstorm, Lin Yue was indeed ready to tear down this layer of wall and expand the space occupied by the shelter again.

"So, let's plan it."

Lin Yue took out the diary, turned to a blank page, and drew the existing square meters and the approximate space occupied by each building.

He asked Xiaobai to take him around in the air again, and then came down and made some corrections to roughly mark the more correct diagram.

Then, there is the boring, but necessary demolition work.

To tear down the fence bit by bit, you need only the same tools.

Lin Yue found that the appearance rate of his high-precision research workbench was too high, and it should have a special location in the basement, but at this moment, it had completely become one of the most powerful helpers that Lin Yue would take with him wherever he went.

Today, as a tool for demolition, it is still as stable as ever, and it quickly transforms this large circle of walls into its original stone.

However, at present, these stones are completely insufficient, and the stone walls need to be not only expanded outward, but also thickened.

The height of five meters is enough for now, but it will continue to increase in the future.

After spending a little time, Lin Yue also turned all the walls into raw materials, and at the same time, he also stopped, and immediately launched the second step of action.

"Thickness...... Actually, this is not so easy to say, it depends on the judgment of the system. ”

Lin Yue first built an ordinary wall, and then immediately built a wall next to it, so that they were completely attached to each other.

[You have obtained the blueprint for the thickened wall!] 】

Oh, and sure enough, the system is quite convenient.

Lin Yue continued the previous operation and pasted the two thickened walls together.

[You have obtained the blueprint of the extremely thick wall!] 】

He made the very thick wall again, and then continued to do the same as before.

After repeating this a few times......

[You have obtained the blueprint of the thickened wall!] 】

This time, after Lin Yue made it again, as a result, a city wall with a length and height of five meters and a width of two meters also stood in front of him in an instant!

Two meters thick...... It's okay.

For the time being, the two-meter-thick walls should be able to ignore the attacks of mutated creatures, lizards, and beggars, and the platform at this width will allow the medium electric sentry machine gun to sit directly on it without having to build an appendage such as an arrow tower against the wall.

Merely......

"The number of stones needed for a unit of thickened city wall is one hundred, emmmm, which is really a test of my stone reserves."

The thickness of the walls is acceptable, but the length is also longer than the previous one, and the total amount of stone required becomes a considerable number.

Lin Yue drew again in his diary, centering on the main refuge, and quickly determined the side length of the city wall to be done this time!

"If it's 500 meters, it should be enough to expand the existing level by more than double the existing one, and if it's bigger, the amount of stone needed will rise even more, if it's not enough, it's not fun."

Lin Yue took out the box ruler, set off from the center of the main shelter, and measured a full two hundred and fifty meters to the south, and then measured two hundred and fifty meters in other directions.

In this way, it is only necessary to connect the extensions of these four points together to get the specific location of the wall that needs to be built on each side of the 500-meter-long wall.

Soon, with the help of Xiaobai and Xiaomeng, these four lines were successfully drawn.

The next thing to do is to prepare the materials.

"The walls of a unit are five meters long? If you want a wall of 100 pieces, the total demand is 10,000 units of stone on one side, and 100,000 units of stone on four sides...... That's a lot. ”

Lin Yue immediately gathered all the stones that had just been demolished, plus all the stones placed in the large warehouse and in the open air, and found that there were less than 23,000 units.

For the rest, he had to go to the "pyramids" on Lake Lévesque and the saltpeter mines.

On the other side of Lake Lévek there are several pyramids of stone, iron and coal that have not been fully moved, and there are also pyramids of saltpeter ore and so on that are also made up of saltpeter, which are mainly stones.

If all of this is collected, it will not be a problem to meet the stones needed for evacuation.

In addition, it can also meet the stone needed for the doomsday bunker and wall that will be built on the side of the crude oil mine!

"Xiaobai, it seems that I have to trouble you for a while, let's try to get this matter done within today...... Xiaobai? ”

Lin Yue was talking to the little friends around him, and when he turned his head, he found that it was not suitable for Xiaobai, but Xiaomeng with a confused face.

"Whoa?" Xiao Meng expressed his incomprehension to Lin Yue, who had been talking to himself, and when he heard that the master was looking for Xiaobai, he quickly pointed him the way.

Its huge arms stretched out to the other side, not elsewhere, but where the medium-sized farm was!

"Farms? Farms...... Good guys, look at those chicks. Lin Yue couldn't help but shake his head.

Xiaobai seems to like those hatched chicks, yesterday they were just put into the medium-sized farm, Xiaobai was busy, and even went to the cub activity greenhouse to lie down for a long time.

Now this kung fu, Xiaobai may think that there is nothing wrong here, so he went directly to the farm, and he is really concerned.

Lin Yue even felt that Xiaobai was more concerned about breeding than himself.

It seems that after the first eggs of this group of chicks are laid in the future, Xiaobai will also be allowed to eat them first.

Lin Yue quickly ran to the door of the farm, and a burst of "twitter" sounds also came from inside.

Anyway, after this morning, I really haven't seen what the chicks look like, I don't know if they are sick or hung up because of malnutrition or the like?

Although Lin Yue has never raised chickens, he has watched some similar breeding programs on TV in the orphanage.

He knows very well that the breeding industry is actually quite troublesome.

Especially breeding chickens, it is a variety of things to worry about, whether you pay more attention to food and drinking water or sick or what other breeding attention points, chicks hang up for various reasons, in fact, it is quite easy to do a thing.

After all, it takes a long time to grow from a chick to a laying hen.

Maybe there are more than 100 chicks, and it is possible that less than two or three percent of them are left in the end.

Lin Yue walked into the farm and went straight to the activity greenhouse.

Yesterday he put enough feed and water, starvation and thirst should not be there, but considering the resistance of the chicks or something......

Lin Yue pushed open the door and found that the Xiaobai he was looking for was sitting on the ground inside the door.

The little guy folded his wings, but his huge body took up a lot of space, but Xiaobai was trying to shrink together as much as possible, leaning gently against the wall in the corner of this greenhouse, letting the "little chicks" run and jump around on it.

"Quack......" Xiaobai squinted his eyes, as if he was enjoying the present time, and seemed to dare not make any big movements except for breathing.

However, Lin Yue's attention was not on it.

It's those "chicks".

Yesterday there were still some chicks with fluffy bright yellow fluff, but at this moment they actually have white feathers on their bodies, and their body size is several times larger than yesterday, and even the difference between roosters and hens can be seen!

"It's ...... What is the situation? That's a bit outrageous, right? ”

Today's chicks have grown from chicks to chicks in just one day!

And at this rate, Lin Yue felt that if one day, they would also grow from small chickens to big chickens!

"Is that the reason for the feed? But it's a little too scary...... Well? The feed is all gone? "Good guys, it's a surprise everywhere, no, it should be said "frightening".

Lin Yue searched around the greenhouse, but did not find any dead chicks, or any similar traces.

Wouldn't it, the survival rate is still 100%? Don't you want to be so strong?

And there is another point that makes Lin Yue a little unbelievable.

All the chicks drained their excrement to a corner of the greenhouse, where there was a small basket that was already there, and although the smell was indeed unbearable, it also made the greenhouse not as dirty as expected.

It can even be said that it is too neat.

"Xiaobai, you do me a favor and put these chickens in that activity area outside."

Lin Yue still felt a little incredulous, what kind of situation was this.

It's just a matter of growing up fast, and the survival rate is 100% outrageous.

"Quack." Xiaobai got up gently, and the chickens immediately jumped off the big guy's body.

Then, after Xiaobai's soft roar again, the chickens immediately stood up straight like the little soldiers!

"Yoh?" Lin Yue didn't expect this to happen at all.

Can Xiaobai still command the chickens?

Although they stand sparsely and the team formation is nothing, they can make a chick with an almost no IQ to obey orders and stand like this, Xiaobai is quite powerful.

Xiaobai let out a soft cry again, and then, these chickens actually walked past Lin Yue's feet one by one and went straight to the activity area!

Well? Do you have a flute or something in your mouth?

Lin Yue couldn't help but think of the story of Hamerlin's piper, but his Xiaobai really didn't have a flute.

As the chickens poured out one by one, and one by one poured into the activity area, Lin Yue once again asked Xiaobai to order them to stand, and he also took this opportunity to count all the chickens immediately.

One hundred and four chicks, one no more and one no less.

Of these, forty-one are roosters and sixty-three are hens.

"It's amazing, I really didn't expect it." Lin Yue sighed again in the activity area.

Xiaobai was able to train the chickens to be so obedient in a short period of time, which is really a bit "magical".

Here, Lin Yue bought another bag of stones from the Survival Point Mall, put it and water in the feed trough and drinking trough, and greeted Xiaobai.

"Xiaobai, you are really amazing, but it is true that you will have to bother here in the future, and it seems that it is really not far from the days when we live the freedom of eggs."

Lin Yue patted Xiaobai's broad shoulders with satisfaction, and the breeding industry has entered a benign track from the beginning.

"Oh yes, and what about the fish? Isn't it time to take a look at the vegetables you grow? Xiaobai, before we go to get the stones, we really have a lot of things to do. ”

……

……

"You...... Do you really want to do this? Lin Yue doesn't feel like a human being! ”

"He can even kill nearly 10,000 lizardmen defenders, and many of us, that guy is ridiculously strong, you, you're kidding, right?"

In the darkness of the underground ruins, the man looked at the system's chat panel flickering in front of him.

These two neon beggars, who had just decided to join his forces and wanted to become his subordinates, couldn't seem to believe that this kind of thing could succeed when they heard him say that he was going to kill Lin Yue.

"Yanagisawa and Suzuki, you two only need to join me with your forces, and I will also take you and other people who are also dissatisfied with that Lin Yue to kill Lin Yue, this kind of thing, I don't want to repeat it, what do you say?"

The man snuffed out the cigarette butt that was about to burn out in his mouth, took it in his hand and bounced it out.

The flames burst into full bloom among the corpses of a group of lizardmen and beggars!

"But ......"

"No, but, join me, or die, it's as simple as that."

“…… I—We get it! ”

"Understood, fine." The man closed the chat panel, looked back at the old man behind him, and smiled softly.

"The team has expanded again, is there more than a dozen people? However, old man, I also want to say that there are many people, I'm afraid it's not Lin Yue's opponent, Lewick wasn't an example last time? ”

"Uncle Sun, don't be funny, what are the five hundred people in Lévesque?" The man snorted and lit another cigarette, "Five hundred people can't stop it, what about five thousand, fifty thousand?" Is he a god? ”

"Hehe, 50,000? Do you have enough to scrape together so much? By the way, are you hiding something from all of us? The old man also smiled, "If we exchange secrets, I can guarantee that the secret I tell is much weirder and bizarre than the one you hid!" ”
