"This..." Seeing the perplexed look on the other party's face, Li Tai struggled and said, "I like tea eggs."
"Go back to the queen and send someone to investigate." After the others left, Li Tai sat in his yard. There was already steam in the pressure cooker. As the steam spurted out from the air port at the top, the small wheel above began to rotate. , the rotation speed is quite fast.
While observing the force of the steam, Li Zhi came with a basket of peaches.
"My brother-in-law asked me to bring these. He said there are so many on Lishan Mountain that we can't finish them all." Li Tai picked up a peach in the basket, took a bite and the juice splashed, looking at the wheel that was constantly rotating above the pressure cooker's vent.
Seeing the emperor's brother being so quiet, Li Zhi took a small bench and sat down, observing the air vent on the pressure cooker.
"Do you understand?" Li Tai asked curiously. Li Zhi, who is only ten years old, is usually obedient and sensible, but he often has some fantastic ideas.
Unlike others, Li Zhi's brother-in-law often gave him questions since he was a child, which also led to his way of thinking about things being very different from other peers.
Seeing him reaching out to touch the steam, Li Tai quickly stopped him.
"Do you know how hot this is?" Li Zhi took back his hand and thought for a moment, then said, "Brother Huang wants to use the thrust of this steam to push the wheel?"
"That's what I think." Zhinu is also his brother-in-law's disciple. He has nothing to hide from him. He can say a few words that outsiders can't understand.
As for who to marry, it is not a big deal for Li Tai. It all depends on his father and mother to decide later.
Li Zhi frowned and thought,
"Brother Huang, don't you think it's strange?"
"Why is it weird?" Li Zhi looked at the pressure cooker,
"The thrust of this steam is always limited. Even if the emperor builds a pressure cooker that is ten times larger, the thrust of the steam will be the same. My brother-in-law said that air pressure is the same as weight, and they are constants in the world. ." Hearing what Zhinu said, Li Tai's mind suddenly opened up. Even if the volume of the pressure cooker is increased regardless of the cost, the steam thrust obtained will remain unchanged. The internal steam force has a limit, which is related to the volume. unrelated.
Looking at Zhinu in surprise, Li Tai asked in surprise: "How did you think of it?" Li Zhi scratched the back of his head and said with a simple smile: "My brother-in-law taught me. The relationship between water pressure and air pressure is the same. How big the pressure is has nothing to do with its area, but is related to its depth. The size of the air pressure has nothing to do with its volume." While talking, Li Zhi added: "In the past, I could get some insights by looking at the water valve made by Master Yan. Maybe this Just apply what you have learned as your brother-in-law said." Following Zhang Yang, he would also understand these knowledge, but he was not as thorough as Zinnu.
The younger siblings have been learning skills from their brother-in-law and the emperor's sister since they were young. Li Tai realized a very serious problem. The way his younger siblings looked at things had changed, and this change would affect them for a long time.
Li Tai held his forehead in pain,
"How terrible are the children taught by my brother-in-law."
"Huh? Brother Huang, what's going on?" After hearing his words, Li Tai regained his composure and said,
"It's nothing, I'm just feeling emotional."
"Well, brother Huang, you don't have to feel too much. In fact, my brother has a way to crack it." Li Tai cheered up and watched him draw pictures on the ground.
"Brother, let's see that water pressure is sometimes the same as air pressure. The reason is the same as the reason why armies going to Tubo will suffer from physical discomfort. This is because we have adapted to the air pressure and environment of the Central Plains. This is like fish in deep water rarely going to shallow beaches. The reason." Li Zhi was talking and drawing pictures on the ground.
"It's like water pressure. Increasing its depth can increase its pressure." The courtyard was very quiet. Three or two guards stood outside the courtyard, guarding His Highness the King of Wei and His Highness the King of Jin.
Occasionally, some villagers pass by, but they don't stay too long. Li Tai has been in charge of the construction of Lishan for so long, and the villagers here respect Li Tai very much.
"Install a pipe outside the pressure cooker. This thin pipe is equivalent to increasing the depth. This artificially increases the air pressure difference. If we need a larger torrent, we need to narrow the river." As the imperial brother It was a bit embarrassing to have to be instructed by his younger brother, but what Zhinu said did make sense. Li Tai felt that he was about to find the secret of steam, and a brand new door was opening.
At this moment, the gap in the door can be seen. Behind the gap, you can definitely see a wider world. Li Tai clenched his fist with excitement in his heart.
"The steam accumulates in the furnace and is forced into a narrow tube. So you are like water flowing from a wide river into a narrow ditch. The pressure inside will be greater, so that when it comes out of the tube The power generated at that time will be even greater.”
"What happens next?" Li Tai continued to ask. Li Zhi frowned and scratched the back of his head.
"Brother doesn't know what to do next." However, Li Tai still gained a lot. He looked at the picture drawn on the ground, and a plan slowly emerged in his heart. From practice time and time again, he knew that this method was It's feasible, and the principles my brother-in-law said are also applicable.
"I'll ask my brother-in-law when I go back. My brother will go back first." Li Tai still looked at the pictures on the ground and said, "Will my brother-in-law still give you questions now?" Li Zhi shook his head.
"The magnet question my brother-in-law gave me last year hasn't been finished yet. Why would he give me another question? Master Yan said that casting magnets is very difficult, and I don't know what's going on now." After saying that, Li Zhi left.
Li Tai drew down the picture on the ground, and Zhinu just mentioned an idea and method. He still needed to improve the idea and try it a few more times.
On Lishan Mountain, Lishan is extremely hot in summer. In order to survive the scorching heat, Zhang Yang built a waterwheel by the Huaqing Pool. The eaves of his new home were already lengthened. The waterwheel brought water to the roof and flowed down. As a result, the temperature in the house increased. It can drop a lot, and the water flow will cut off a lot of heat.
The little bear and five other cubs also stayed under the eaves and refused to go anywhere else. The children were taking a nap. Zhang Yang sat at the table, listening to the squeaking sound of the waterwheel, and finally finished reviewing the last memorial.
The imperial court transferred the money that had been accumulated for half a year to the memorial, and the couple only took two months to approve it.
Among them are the supplement of credit, the payment of salaries to officials, and the rewards given by various ministries on weekdays.
Zhang Yang looked at the total credit owed by the court to 65,000 guan, with a surplus of 5,300 guan. In addition, Lishan lent 20,000 guan this time, and still owed 70,000 guan.
Life in court is tight, but I can barely get through it. After sorting out the memorial in front of her, Li Yue handed it to her aunt.
"Auntie, please send these memorials to His Majesty's small palace." Auntie Wang held the baggage in her hand.
"With such a talent as the county prince, he will surely have a prosperous and prosperous day in the future."
"Of course, I have done so many good things in Datang." Li Yue smiled bitterly,
"It's just that the wealth your husband wants is different from others."
"The wealth I want is very simple. I can count money until my hands cramp." Zhang Yang took a sip of tea and calculated the current assets of the court. He was unable to make ends meet and would not go bankrupt. As long as the emperor worked hard, the government's surplus would always turn into A positive number.
The couple is very capable, and Aunt Yang can see it from the sidelines. The couple is very economical in the use of money, and every penny is used in key places. If it were anyone else, this huge amount would be wasted. It’s unclear how long it will take to sort out the accounts.
The couple can squeeze some money out of their teeth to cope with the deficit in the DPRK. The emperor is not a person who can settle accounts, and there is a danger of extravagance and waste. Fortunately, our Majesty knows how to be frugal.
When the costs are spent, it’s time to recover the capital and make profits. Zhang Yang opened a map, which was a map of the Western Regions, and finally his eyes fell on the border of Persia.
Just as he was thinking about this, Li Zhi came back in a hurry. He washed his face with the water flowing from the eaves, and then took a sip of cold water to relieve himself from the scorching heat.
This summer, the weather was so hot that even Li Chengqian, who was in the East Palace, came to Lishan. People in Chang'an City were fleeing, going to the suburbs or the mountains and forests to escape the summer heat.
Due to the terrain, Chang'an City is now like a huge steamer. There are only some pedestrians in the evening and morning. On weekdays, Chang'an City is like an empty city, and everyone who can walk has left.
The scorching heat of the dog days also made Li Shimin give up the idea of returning to Chang'an City, and needed to stay in Lishan for a while.
After the hot summer day was over, he planned to return to Chang'an City. The emperor also continued his days of eating and drinking in Lishan Mountain.
Anyway, it was Li Tai's money that was spent. Li Tai was already a member of the village, so it didn't matter to him. The emperor was different. The emperor needed money when he came to escape the summer heat.
The emperor's summer vacation was not a happy one. First, the court officials impeached the Ministry of Rites and fined him his salary. Then he waited for Songtsen Gampo to come to Chang'an City for a confrontation before making any plans.
It was obviously inappropriate to deal with Zhang Yang while listening to the court officials' impeachment before the victim arrived. Li Shimin was still very clear about this.
I just lament that other people's ministers are submissive, but our Majesty's ministers will strike hard when something goes wrong.
Whenever the emperor did something wrong, his ministers would criticize him with reference to scriptures and draw inferences from one example.
After a while, Li Zhi came with a picture.
"Brother-in-law, this is the picture I drew." Zhang Yang came out of his leisurely state of mind and looked at the drawing carefully.
"Is this a pressure cooker?"
"Well, I want to help Brother Huang sort out some of his troubles."
"Yeah." Zhang Yang nodded and looked at it,
"What's the thickness of your gas pipe?" Li Zhi looked at the drawing and scratched his head and didn't know how to answer for a while.
Zhang Yang added: "Look at the length of the steam pipe. If it is more than ten feet, will it take up too much space? Also, how much water is needed to generate enough steam..." I mentioned many things to him in succession. Question, brother-in-law's words were a bit harsh. Li Zhi pouted his lips in grievance and lowered his head as if scolding.
Zhang Yang patted his shoulder and said: "Don't rush for success when things happen, that fat guy..." He paused and then changed his words: "Actually, your imperial brother also has his own plans. You don't have to rush to help him. You need to do what you want first." The basics of learning are mastered first.”
"Well, remember my brother-in-law's teachings." In the hot summer of Guanzhong, crops will die if there is no water for irrigation. In the evening, the villagers in the village opened the canals to release water.
After the scorching heat at noon, it felt much cooler in the evening, and the village regained its vitality. The blacksmith workshop has also temporarily stopped working, and the whole village is trying to survive the scorching heat and wait for the scorching heat to pass before working again.
Today Li Shimin invited Kong Yingda to Lishan. He invited Kong Yingda to escape the summer heat and also to teach the children.
Kong Yingda was talking about the "Book of Changes". A pavilion was set up outside the small palace, and Li Chengqian and Li Shimin were also listening.
Li Shimin was looking at the memorial in his hand. This was a brief summary of the prince's affairs in the court these days, and also what happened in the court these days.
Now the princess also gave birth to a child for Cheng Qian. The queen was worried about the child and asked Li Chengqian to return from the East Palace with his wife and children.
In the pergola, Kong Yingda talked about benevolence, justice, propriety, filial piety and brotherhood. Princess Dongyang, who is usually sensible, well-behaved and quiet, listened to Master Kong Yingda's story. Gao Yang couldn't stand it anymore and stood up and said: "Old Master, students think that benevolence, justice, etiquette, filial piety and brotherhood are too restrictive. If someone is unruly, we can't dissuade them." Of?"
"Cough, cough, cough..." Li Shimin, who was sitting outside the pergola, coughed violently. It was like a child's talk. What did a child in Gaoyang know?
Li Shimin calmed down and continued reading the memorial. Kong Yingda added: "Respecting elders and filial piety are the first. Those who have been righteous and benevolent throughout the ages can still convince others." Li Zhi also stood up and said,
"The student thinks there is something wrong with what the old master said." Kong Yingda's brows twitched and he stroked his beard as he watched the princes and princesses stand up one by one. He was afraid that he would not be able to pass this lesson.
Li Zhi bowed and saluted: "According to what the old master said, filial piety and brother-in-law come first, but I heard from my brother-in-law that in life, you should have firm obsessions in your heart, and you should behave in a manner that is honest, trustworthy, just, and harmonious. Respect the Dharma." Kong Yingda hesitated to speak, but felt that there was nothing wrong with what he said, so he couldn't help but ask,
"Who taught you this knowledge in ordinary times?" Li Zhi added: "There should be a distinction between individuals and collectives. It is not right to destroy human desires. We should advocate practicing fraternity and justice." Kong Yingda gasped after hearing this. In one breath, this lesson is impossible to learn.
What the princes and princesses said seemed good, but I always felt that something was wrong, as if they had crushed up the Confucian and Taoist ideas and then added something else.
Kong Yingda asked the children to leave first. The old man walked up to Li Shimin and said,
"Your Majesty, may I ask who is giving lectures to the princes and princesses?" Li Shimin asked in astonishment: "Does the old master think there is something wrong?"
"Who brought up this trend of arguing against ethics." Li Chengqian remained silent and saw that Master Kong Yingda was very angry. Zhang Yang and Yue'er established their own gate in Lishan Mountain. Who brought this trend.
If there is anything really wrong, it is the atmosphere brought out by Lishan Mountain Gate. Zhang Yang has many unpredictable abilities.
Who else could it be besides him? What the school of Lishan Mountain School taught was naturally Zhang Yang’s own knowledge. Who knows who Zhang Yang studied under and where the old man from Qinling came from.
