"I always feel that something big will happen."

In the Political Affairs Hall, when the three prime ministers were having lunch together, Yao Chong spoke out.

"What's the matter?" Zhang said cooperated and asked.

"I don't know." Yao Chong shook his head: "I only know that the Li family village is too calm in the past few days."

"Aren't you looking for mines, mining, or quarry? He doesn't care about gold mines." Lu Huaishen proved that Zhuangzi was not idle.

"Not counting, Zuixianju doesn't count, there's something else." Yao Chong is sure that his sixth sense will not be wrong.

Zhang said to swallow the chicken: "The newspaper is losing money and selling it, so it still prints 300,000 more copies every day and sends it along the river.

The staff sent were clever people who lived from outside to the river, but the village house did not go.

Oh, I understand. If you put it in a few more days, Jingzhao Mansion will advertise. This is a big deal. Yao Xiang is amazing!"

"Is that right?" Yao Chong suspected that after thinking about it, it made sense.

How much does it cost to make money by advertising in Jingzhao Mansion to make an advertisement once?

When Lijiazhuangzi successfully advertises in Jingzhao Mansion, he may set up some other places where newspapers are delivered and then advertise.

"I heard that many students practice writing on the back of newspapers in order to save money. Three cents can read newspapers and write, which is cost-effective."

Lu Huaishen specifically chose the best, which showed that Li Yi provided help to the students again.

"It's a pity that he didn't ask if he could weave mats quickly." Yao Chong regretted that he was 'sick' and always had to find something for Li Yi.

He could go to Zhuangzi in the past, but now he is not allowed to go, which is annoying.

Li Yi in Zhuangzi was not upset, he invented small things, which could also be turned into big things.

A large bucket was installed with a flatbed truck, and there was a pressure well on it, but it was different from the well and the seal was tighter.

The outlet is a small bamboo tube connected to the bucket.

As soon as the person above pressed it, the water sprayed out, and it was still far away, like a toy water gun.

This thing is used in the village to cool down the cement pavement, which is too hot.

People wear shoes and walk on the soles of their feet, not to mention the hooves of livestock.

After slapping the iron palm, he touched the hot cement road, and the horse and the other was unwilling to go up.

The shopkeeper poured water with water. Li Yi felt it was slow and turned around and asked the workshop to make a water gun.

When Li Chengqi saw it, he was stunned for a while and ran over to press it down himself.

He stopped until a bucket of water was left and he couldn't suck it up.

Find Li Yi: "Di Yi, do you know what this moving water-pressing thing can do?"

"Working a water battle, you one, me one, spray each other." Li Yi looked at Li Chengqi.

"Think about another one." Li Chengqi urged.

"There are stone roads in Chang'an City, and it is also hot in summer. It is people who come to splash water to cool down. It is difficult to pull them away with a big wooden barrel."

Li Yi gave another purpose.

"I used a wooden barrel to drill holes and stuffed them first. When I left, I pulled the plug off and sprinkled water as I walked."

Li Chengqi emphasized, you are just pouring water, do you think everyone is so stupid?

In winter, you are skating in the village, so isn’t it just using this method to water the ice?

Li Yi didn't joke: "It can be made larger ones, which require dozens of people to operate to extinguish the fire.

I have a few things to assist in extinguishing fires. I need fewer staff. One person can operate them, and there are still three or four."

Li Yi said that he brought Li Chengqi to the side, with a bucket next to it, a bamboo tube on it, and a tube inside.

Then seal it with sesame and oil sludge, and the bamboo tube is under the one-way valve.

There is also a one-way valve above, which is reverse.

As soon as the pipe is pulled out, the water in the bucket enters the pipe, and the pipe shrinks again, and the water is blocked by the one-way valve of the leather pad and sprayed out from it.

The seal is not good enough, and there is still air coming in, but it can be sprayed out.

Of course, if the front is short, it is OK to block it with your hands.

Or there is a place in the middle that can be pinched flat, pinch it when absorbing water, and loosen when pressing water.

The other one is that two people use a crossbar to press, and one person is responsible for controlling the opposite direction of the pipe.

Once the pressure is pressed, the water is sprayed out, which is larger than the water of a person and is farther away.

The third thing is the syringe made of bamboo tubes, which is pumped and pushed.

Li Yi's small plastic water gun that the child played with at that time was enlarged.

"Make the pressure bigger and dozens of people press together, so that the water can be soaked as high as a few floors, and there is plenty of water."

What Li Yi brought out was a water dragon used in the Qing Dynasty.

The current fire extinguishing tool is a thick bamboo tube that is meter long, and a large water bag is sealed with a leather.

When extinguishing the fire, insert the bamboo tube into the water bag and hold the mouth tightly.

The others pressed the water bag together and the water was sprayed out.

Li Chengqi just nodded. This thing is good, and it is mixed with several kinds.

It is much easier to save it if you go to Chang'an City.

While he was thinking, Li Yi's voice sounded again.

"But if there is a water source, it is best to make a large tank of water for daily use and cover it.

In winter, I used a cloth to wrap it. I saw that I had frozen and knocked off the ice and thawed it with hot water.

It seems to be more expensive, it is better than burning a house or burning people to death.”

Li Yi found that Chang'an had a good layout, one by one.

Each shop comes with a few large jars, which doesn’t matter in summer and keep warm in winter.

"That's right." Li Chengqi recovered from his senses, greeted the people, carried the things and ran away.

Just throw away one sentence, "I won't come back tonight."

Li Yi asked someone to move out another one and continue to cool down the cement pavement.

Not only did we have to descend to Zhuangzi, but the road from Zhuangzi to Chunmingmen is now covered with cement.

A muddy road is preserved next to it, so that livestock without nails can walk.

The road was also hot, and the merchants drove out the carriage. After spraying a bucket of water, they came back to load it, and the other car continued to spray it.

There is no water pump or fire belt, otherwise it will be pumped in the Ba River.

A large wooden barrel made of wood can hold two tons of water in one bucket.

Fortunately, the car is strong enough and there are many cattle and horses at the same time, otherwise this section of the road would not be able to get rid of it.

"Where can I load the water?" Passersby saw it and asked about the water source in curiosity.

"The well water is cool!" the village house replied.

"I wash my hands and take a sip. I'm almost thirsty. Now it's said that the river water is not clean." Passersby came over and reached out.

Wash your hands first, then hold the water and drink it, and wash your face as well.

"Call me to try." After drinking enough, passers-by made new requests.

He operated it and took a few breaths: "It's easy to put out the fire. I run with a big bucket in a car. When I go to the place, the water will spray out so far."

On the way to the city gate, people were washing their hands, drinking water, and saying they could put out the fire.

People are not stupid, they know the use of things.

Li Chengqi returned to the palace with his things and asked someone to fill the bucket with water. He pressed it at the entrance of Xingqing Palace.

Li Longji and the palace maids and eunuchs came out to see.

After receiving the news, a group of people from the Political Affairs Hall not far away also arrived here.

"Look, it's used for water fights, one person, one blows each other, it's hot and cool in summer.

It can also cool down the road surface in Chang'an City, which is better than pouring it into a pot again and again."

Li Chengqi took out what Li Yi said.

Yao Chong took a pump, sucked water and pressed it hard, and the water flew seven or eight feet away.

He smoked again: "Good thing, this gadget is simple to make. As long as there are many people, the fire on the second floor can be extinguished."

Zhang said, "Ordinary people can prepare two places, and they will get fire, and they will go and help them all at once."
