A well was drilled in each yard, using a pressurized water device, and a well platform was built with bluestone slabs.

The so-called pressurized water well, is the use of a kind of groundwater to the surface of a tool, it is made of cast iron, the bottom is a cement block, the head of the well is the outlet, the back is thick and the front is thin, the tail is connected with the center of the water pressure handle, about two or three centimeters long. In the center of the well is a water diversion skin, which relies on the action of this water diversion skin and the well core to lead the groundwater pressure up.

The pressurized water well was drilled under the guidance of Li Ziyu, and the iron casting part was also a drawing drawn by her, which was successfully revised repeatedly.

Among them, the most critical drinking skin, which is also a large elastic animal skin, was installed under Li Ziyu's finger.

No one has ever seen a pressurized water well in the Daye Dynasty, and even the master who drills the well all the year round was also impressed by Li Ziyu's whimsical ideas and admired this little girl.

Of course, it was more exciting, because they learned the good art of drilling wells again. In this way, the well is absolutely guaranteed in terms of safety performance.

Each courtyard is equipped with a separate toilet, kitchen and washroom, and two or three sets of iron heaters are installed in each room, regardless of the main room, which fundamentally solves the problem of heating in winter.

In fact, the installation of heating may seem simple, but there are many key points. For example, the problem of backwater and boiler problems, Li Ziyu studied these problems together with the installation masters, and finally succeeded in installing.

A small boiler is installed outside each kitchen to supply the entire yard with heating.

Toilets and washrooms are next to each other. It was just separated by a wall, and connected by a small door. In the toilet, Li Ziyu didn't make any toilet, just a squatting toilet made of coarse porcelain. A lid is designed on it. After urinating, you can use the water from the next tank to flush it down the drain, and then close the lid so that there is no smell inside.

The sewers of the seven houses were laid with coarse porcelain pipes fired from coarse porcelain, connected with cement in the middle, and finally led to the manure tank outside the north courtyard wall.

The manure tank and its surroundings are made of green bricks and plastered with cement. It is convenient for making manure. And use several bamboo pipes to connect into water pipes, which are used to flush the manure tank.

In order to prevent someone from making a fuss in the manure tank, Li Ziyu also fenced it with green bricks. The top was covered with a large piece of iron. In this way, the smell does not spread and affect everyone's senses.

The urinal opened a door, which was usually locked with a copper lock. To the north of the manure tank is a gentle slope from which a path opens. Twist back to the west side of the house.

All of the manure tank is within sight of the bunker to the north. In terms of safety, Li Ziyu did not leave any dead ends.

A space about seven meters away was set aside between the new house and the north wall, which was the exit and entrance of the underground valley that Li Ziyu had deliberately set aside.

In this slippery place, Li Ziyu built a row of mud and straw houses with a sharp roof, which were divided into ten small courtyards. One of these ten small courtyards is the underground exit, and this secret is currently known only to Li Ziyu and Bu Jiu and Bu Shi.

Immediately against the east and north walls, a series of barns for livestock, carts, firewood, and straw were built.

Now, the bluestone pavement of the new house has led to anywhere it can go. It's no longer a rainy day with feet full of mud.

In the inner room of the five main landlords' houses, Li Ziyu dug another secret passage to the underground valley. The entrance to the cave was left in the northeast corner of the east room.

This cave entrance was secretly dug by Chai Bin and others, and according to Li Ziyu's instructions, this passage led directly to the underground valley, and there was no passage at the entrance of the dead tree cave.

This cave is larger and more spacious than the previous dead tree hole, the ground is all paved with green bricks, and the roof of the cave is supported by thick wood, which has high safety performance. Although it eventually leads to the underground valley, it takes a different path.

Part of the grenade divided into the thunderstone is hidden in this passage, and at the end of the passage is another mountain. Li Ziyu had already asked Chai Bin to inspect near the peak, and she had taken the time to walk it herself.

It was found that there was also a smaller valley under that peak, although it was not as big as what was originally discovered, but Li Ziyu didn't want to live in it, and he was content.

She just wanted to find a place to store the grenades, and they all knew where the grenades were stored in the past. But that place will tell Ren Xiaohang sooner or later, relatively speaking, it is not very safe.

It's not that she doesn't believe in Ren Xiaohang, on the contrary, Ren Xiaohang is someone she trusts immensely.

However, Ren Xiaohang is loyal to the current emperor, who dares to say that there is no emperor's eyeliner by Ren Xiaohang's side now. If Ren Xiaohang knew about the grenade, then the emperor would definitely know about it.

I have been busy for a long time, but I don't want to hand it over obediently. Even if you have to hand it over one day, you have to leave some way back for yourself to save your life.

Li Ziyu took his younger siblings around the seven houses, and then climbed the courtyard wall along the road to the city. Xiaoshan was the first time they had seen this kind of courtyard wall, and they were all excited.

"Sister, why is the courtyard wall of our house built like this?"

Xiaoshan looked at the houses in the village not far away, and looked very short on the courtyard wall. And the courtyard wall of his house looks too special, I can't help but ask.

Xiaowen frowned tightly, as if she was also thinking about why her sister did this.

Chai Bin, Wang Qiuyue, Ouyang Luo and Xiao Ou Li were on the side and did not speak. Chai Bin and Wang Qiuyue knew the inside story, so they didn't say anything. Ouyang Luo and Xiao Ou didn't know anything, and when they saw Xiaoshan asking, they also hoped that Li Ziyu could explain.

Because the Li family's new house really stands out in the village, it is too conspicuous! Doesn't this invisibly pull hatred points?

Xiao Wu, Xiaohu and Xiaolan, who were playing on the side, understood what their brother meant, and looked at Li Ziyu in a daze.

Li Ziyu stood on the battlement, her eyes subconsciously looked in the northwest direction, turned to look at the family in front of her, and said a news that shocked them.

"It may not be long before we have a war here."

"What? It's true? Ouyang Luo first screamed in fright.

Xiaoshan and Xiaowen were also shocked by the news, and the two glanced at each other, but neither of them spoke.

"Sister, what is war?" Xiaohu noticed that the atmosphere around him had changed, and asked with a tiger face.

Xiaolan subconsciously leaned into her sister's arms, as if only in this way did she feel steady.

Xiao Wu's eyes lit up suddenly, and there was excitement, yearning, and impatience in them.

Li Ziyu looked at his little brother, touched his head lovingly, and said, "War is when the hostile sides keep fighting, and then people keep dying." ”

"Huh? O dead man! Sister, tell them not to fight. Lan Lan is afraid! Xiaolan snuggled in her sister's arms, and when she heard that the dead man subconsciously knew that it was not a good thing, she pulled her sister's shirt and said.

"Silly boy, how can my sister manage such a big thing?" Li Ziyu hugged Xiaolan's growing body and sighed.

The reason why she told her family the news of the impending war was to make them mentally prepared. When war comes suddenly, don't panic.
