Song Jing was a very upright person. Even after he resigned, he did not meet any officials.
Now that Song Jing was agitated, he actually wanted to help Li Yi impeach someone.
In his opinion, Li Yi must have committed a heinous crime if he wanted to impeach someone.
"Old Song, you are indeed a good man. Do you have teeth?" Li Yi was touched. He wanted to see Song Jing's teeth again.
"I will help you too." Bi Goo was depressed. Xiao Yi knew how to bully the right person.
"Old Bi, thank you. Look for me again in the future." Li Yi was satisfied.
"It is cooler in Zhuangzi than in the Imperial City. What good things did you use?" Bi Goo quickly changed the topic. He was hot.
Li Family Zhuangzi gave people the feeling that the overall temperature was low. It was even more obvious in the cafeteria.
"There are many rivers. Zhuangzi has many small canals. When the water flows in the canals, it will naturally cool down. There are many houses in the Imperial City. When the wind blows, it will be blocked."
Li Yi expressed that he did not have any good ideas.
The cafeteria was cool. There were also cement canals under the cafeteria. When the water flows, the temperature above was of course lower.
"Is there any other way? The ice given by Her Majesty is not very good. "
Song Jing helped to ask. He was also hot. If he put a basin of ice given by Her Majesty in the office, the effect would not be obvious.
"There is ice? Isn't there a human-powered fan? Let people use the fan to blow.
Big Brother and Third Brother were in Zhuangzi's courtyard. When they came, they had this cooling method.
I have air-conditioning, but the situation is special. I can't let you use it. "
Li Yi suggested another way. Artificial ice. People would step on the fan and rotate it. It was better than using a fan. It was not as tiring.
"It is not good to use people. Is there anything else?" Song Jing was not willing to let others work while he enjoyed the cool.
"Is there wind in the Imperial City?" Li Yi frowned. This energy was conserved. It was easier to operate when there was wind. Wind itself was a type of energy.
"The Imperial City has walls. How can there be wind? Unless it's high up. "
Bi Goo looked at Li Yi as if he didn't even know the structure of the Imperial City.
"That's enough. Can you erect something that's a few dozen feet or a few dozen feet tall in the Imperial City? If you can erect it, then it'll be cooler."
Li Yi finally thought of an idea. Yes, there was wind in the sky.
"You want to fix a windmill? Then it's used to drive the connecting rod into our office to connect to your fan? "
An image appeared in Bi Goo's mind. It was a windmill with a sail. It would spin no matter which angle the wind blew from.
When it was set up, there were a series of connecting rods below, and all kinds of transformations, just like the mill by the river.
"Actually, you can make a crooked bamboo chimney that connects to the office. When the wind blows in from above, there are many openings below, and they are small, so you will feel cool. "
Li Yi was talking about the method of using plastic bottles as air conditioners. It required an external force. How could it blow without wind?
There were such situations. Some buildings had special corridors. The wind blew down from above. It was hot outside, and the building was cold and gloomy.
The key was that there was ice that could be used. Actually, even water could be used to cool it down.
"Well water, when the wind blows, it will save the ice. The wind will feel very natural. Can you use it in the Imperial City?
You can also take down a large tube from the walls of the Imperial City and place a large wooden trough below it. The trough will be filled with well water from the pressure well.
Put it on all four sides of the city walls. No matter where the wind blows from, it will cause the temperature to drop. "
Li Yi gave another idea. Otherwise, he really had no other ideas.
Song Jing and Bi Goo looked at each other and shook their heads. How could it be possible? How could the Imperial City let you do such a big project?
"Why don't we create artificial fog? I will design a nozzle and place a hot air balloon in the Imperial City. Pull a pipe up and spray it, wasting petrol.
Actually, we don't need a hot air balloon to create artificial fog. The pipe is long enough and the pressure is high enough. We can just spray it into the sky like a fire truck. "
Li Yi tried to think about it in a simple way. Spraying water to cool down was something that everyone knew.
"The pipe can be removed at any time?" Song Jing knew that the tools used to put out the fire, such as the pump and the pressure car, were all provided by Li Yi.
Now, there were cars in the city that would spray water to cool down the road every day. However, if the water was sprayed too high, it would be like rain.
"It can be removed. Also, if you want to spray water, you can spray water. If you want to spray, you can spray fog. Just add a small modification to the top of the head. It's very simple."
Li Yi promised that the tighter the spray bottle used at home, the more water mist there would be. When it was opened, the internal structure was a gasket with one or two vertical water outlets.
After adding a screwdriver, the outside of the gasket would gradually shrink outwards. The tighter the screwdriver was, the less water would come out of the gasket. However, with the pressure, there would be mist.
"After dinner, Xiao Yi, you draw a picture." Bi Goo agreed.
With an additional spray car, they could leave at any time. No one would reject it. Everyone would be able to cool down.
Li Yi poured wine for both of them. "I can only draw a man-made picture. It needs people to step on it and not suppress it."
"Why?" Song Jing wanted to know what else was there to suppress.
"The blowtorch on the hot air balloon is that. Old Song, do you want to learn?" Li Yi pointed to the canopy.
Song Jing shook his head like a rattle drum. "No. I am not interested in those things."
He already knew that when he returned to Chang 'an, he would learn it. The hot air balloon and gunpowder were top secret. No one was allowed to ask about it.
Otherwise, why did the Li Family Zhuangzi have three layers of protection?
He heard that this was how Tubo was cheated. 250,000 yuan.
After dinner, Li Yi gave each of them three big pills made of hawthorn, licorice, dark plum, and Luohan fruit.
"Eat one first. Eat one before going to bed. If you are thirsty in the middle of the night or wake up in the early morning, eat one more. You two eat too much spicy food."
Li Yi was afraid that both of them would have constipation if they ate two spicy foods, so he gave them some supplementary food.
The two of them were not polite at all. They ate one on the spot. It was sour and sweet. The sweetness of Luohan fruit was different from normal sweetness.
"When you two leave tomorrow, let the people in Zhuangzi take a few sets of equipment. Now I will draw and ask the workshop to do it. It will be fast."
Li Yi motioned for the palace maids and eunuchs to arrange accommodation for the two of them. He went back to draw.
Song Jing and Bi Goo lived in the same courtyard. They were not in a hurry to enter the room. They drank tea at the stone table outside.
Zi Yu and He Yan stayed behind to serve the two of them. No matter what, they were two ministers.
The two of them had eaten too much of their own Gen Ban, so they sat next to them and drank tea together.
"You two go back to your rooms and rest." Bi Goo ordered. There were many rooms in the courtyard, and there was a place for Gen Ban.
"Minister Bi, let them take a bath. It will be cool and refreshing." Zi Yu suggested in a low voice.
"Yes, go take a bath." Bi Goo agreed.
The two of them left happily. They had long wanted to take a bath. They had not washed their hair for three days.
"Xiao Yi really has a way. It will be cool in the imperial city tomorrow." Bi Goo felt that his goal had been achieved.
"Who would have thought that Li Yi, who made such a big thing, is preparing for the winter war? No matter how much money he earns, I am not jealous, and I don't have to take it from him. "
Song Jing sighed with emotion about Li Yi providing things for the border soldiers.
"This old man is …" Bi Goo was anxious. He felt that Song Jing was alluding to him.
"I'm not talking about you. It has nothing to do with you. I'm talking about this matter." Song Jing explained.
