Bringing System to Great Tang

"The old man always feels that something big is going to happen."

In the political affairs hall, when the three prime ministers were eating together at noon, Yao Chong said.

"What's the matter?" Zhang said in cooperation to ask.

"I don't know." Yao Chong shook his head: "The old man only knows that Li's Zhuangzi has been too calm in recent days."

"Aren't they looking for ore, digging, or quarrying stones? He doesn't care about the gold mine." Lu Huaishen proved that Zhuangzi was not idle.

"No, it doesn't count as Zuixianju, there's still something to do." Yao Chong is sure that his sixth sense can't be wrong.

Zhang said that he swallowed his chicken: "The newspapers are selling at a loss. They still print out 300,000 more copies every day and send them all the way down the river.

The staff sent were clever people who lived by the river from outside, and the farmer did not go.

Oh, I see. If you shop for a few days, Jingzhao Mansion will advertise. This is a big deal. Yao Xiang is amazing! "

"Really?" Yao Chong doubted, and it made sense to think about it accordingly.

How much does it cost to make money from advertising?

When Lijiazhuangzi succeeds in advertising in Jingzhao Mansion, he may set up a spot in other places where newspapers are delivered, and then advertise as well.

"I heard that many students practice writing on the back of the newspaper in order to save money. They can read the newspaper and write for three dollars, which is cost-effective."

Lu Huaishen specifically chose to say that it shows that Li Yi has provided help to the students again.

"Unfortunately, I didn't ask him if he could make up the mat quickly." Yao Chong regretted that he was ‘ill’ and always wanted to find something for Li Yi.

Before, he could still go to Zhuangzi, but now he is not allowed to go.

Li Yi in Zhuangzi is not upset, he invented small things, which can also become big things.

A large bucket is loaded with a flatbed truck. There is a pressure well on it, but it is different from a water well and has a tighter seal.

The water outlet is a small bamboo pipe connected to the bucket.

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

Zhuangzi used this thing to cool the concrete road, it was too hot.

The soles of people walking on with shoes are hot, not to mention the hooves of livestock.

After hitting an iron palm and touching the hot concrete road again, the horse and the cow were unwilling to go up.

The villager splashed water, Li Yi felt slow, and turned his head to let the workshop make a water gun.

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

When the bucket of water had a bottom and couldn't **** it up, he stopped.

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

"Fighting a water fight, one for you, one for me, spray each other." Li Yi looked at Li Chengqi.

"Think of one more." Li Chengqi urged.

"The city of Chang'an is a stone road. It's also hot in summer. People come to splash water to cool down. It takes a lot of effort. It's better to use a big wooden barrel to walk."

Li Yi gave another purpose.

"I used a wooden barrel to punch a hole and plug it first. Pull out the plug when I left, and sprinkle water as I walked."

Li Chengqi emphasized that you just splashed water. Do you think everyone is so stupid?

In winter, your Zhuangzi is skating, isn't it the way to pour the ice?

Li Yi is no longer joking: "You can make a bigger one, and it requires dozens of people to operate it to put out the fire.

I still have a few things, auxiliary fire extinguishing, which requires less manpower, one person can operate it, but three or four. "

Li Yi said he brought Li Chengqi to the side. There was a bucket next to him with a bamboo pipe on it and a pipe inside.

Then use hemp and sludge to seal, and under the bamboo pipe is a one-way valve.

The above is also a one-way valve, reversed.

As soon as the pipe was pulled out, the water in the bucket entered the pipe, and the pipe shrank again. The water was blocked by the one-way valve of the leather cushion and sprayed out from above.

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

Of course, if the front is short, you can block it with your hands.

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

The other is that two people use a cross bar to press, and one person is responsible for holding the pipe in the opposite direction.

When pressed, the water sprays out, which is larger and farther than a person's water.

The third thing is a needle made of a bamboo tube. Pump water and push it.

Li Yi zoomed in on the plastic water gun used by children at the time.

"Make the pressure one bigger, and dozens of people can press it together, so that the water can shoot up to several floors, and there is a lot of water."

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

The current fire extinguishing tool is a thick bamboo tube with a length of ten feet, and a large water bag is sealed with leather.

When putting out the fire, put the bamboo tube in the water bag and hold it tightly at the mouth.

The other people pressed the water sac together, and the water sprayed out.

Li Chengqi just nodded, this thing is good, it's a mixture of several kinds.

It is much more convenient to save by taking the water in Chang'an City.

As he pondered, Li Yi's voice sounded again.

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

Wrap it with cloth in winter, knock off the ice when you see it, and heat it to thaw.

It seems to be more expensive than burning a house and burning people to death. "

Li Yi found that the layout of Chang'an was good, one by one.

Each workshop is equipped with several large tanks, it doesn't matter in summer, but keeps warm in winter.

"Exactly." Li Chengqi slowed down, greeted people, carried things up and ran away.

Just drop the words ‘I won’t be back tonight’.

Li Yi asked him to move out another one and continue to cool the cement road.

Not only is it necessary to descend in Zhuangzi, but the road from Zhuangzi to Chunmingmen is now paved with cement.

There is a mud road next to it, which is convenient for livestock without nails to walk.

The road was also hot, the dealers drove out the carriage, sprayed a bucket of water, returned to load, and another car continued to spray.

There are no pumps and fire belts, otherwise it would be pumped in the Bahe River.

A big wooden barrel made of wood can hold two tons of water.

Fortunately, the car is strong enough and there are many horses and horses, otherwise this section of the road will not be sprayed.

"Where did you install the water?" Passers-by saw the water source and asked curiously.

"Well water, cool!" the farmer replied.

"I washed my hands, took a sip, and almost killed me of thirst. Now they say that the river is not clean." A passerby came over and stretched out his hand.

Wash your hands first, then hold the water to drink, and wash your face by the way.

"Tell me to try it." After drinking enough, passers-by made new demands.

He manipulated it and took a breath: "It's easy to put out a fire, run with a big bucket in a car, press down on the place, and the water sprays so far."

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

People are not stupid~www.wuxiahere.com~ know the use of things.

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

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

After getting the news, a group of people in the political affairs hall not far away also rushed here.

"Look, they are used for water wars, one for each person, spraying at each other, it is hot and cool in summer.

It can also cool down the road surface in Chang'an City, which is better than splashing over and over with a basin. "

Li Chengqi took out the set of remarks Li Yi said.

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

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

Zhang said and then said: "Ordinary people can have two in their homes. Wherever there is a fire, you can call out and help all."
