At night, Li Xingzhou carried Qiu'er back from the backyard with a cat's face.

The little girl was burned on her hand, which made him feel heartbroken. With the help of Zhao Si, Tie Niu and others, her steam engine could actually move long ago, but it doesn't mean it can be used when it moves.

Perhaps it was because of steam power that the first industrial revolution was triggered, leaving many people with the impression that steam power is an emerging concept.

However, it is not. As early as the second century BC, about 2,200 years ago, the Greeks tried to use steam as power.

In the 15th and 6th century, more than three hundred years before the First Industrial Revolution, some European countries had begun to use steam as power, but it was not popular and the technology was not mature until Watt's improved steam engine appeared.

It wouldn't be difficult if I just wanted to push objects with steam.

A simple pot of water can be achieved by having less water. Once the water is opened, the lid begins to jump. Follow this idea, make the kettle long and the lid is built into it, which can push the lid farther away. Adding a lever on the lid can lead to the force to pour out.

At first Qiu'er thought so, so the steam engine she designed was long cylindrical, and it also successfully promoted a wooden wheel more than one foot high to rotate.

But soon she was disappointed, almost exactly the same difficulties that everyone encountered in her previous life.

The difficulty of using steam power is not to realize dynamic energy conversion, but how to improve the conversion rate.

It's like this afternoon, Qiu'er complained to him with a pout when he saw him coming. They used two large bags of coke and the steam started to move. They took a standard carriage wheel for less than half an hour. Zhao Si and Tie Niu were both amazed and very happy.

Qiu'er was depressed and even lost her mind and accidentally burned herself.

Because she designed the steam engine at the beginning, for practical purposes, and according to this energy conversion rate, it is necessary to push a large ship to walk for several days in a row, and it is necessary to bring coke heavier than the ship on the ship...

That's why she is not as blindly optimistic as Zhao Si and Tieniu, but she is very disappointed.

Li Xingzhou comforted her with a light little girl on her back: "It's okay, take it slowly, it's always possible. Maybe you can think of an integrated design."

Qiu'er lay on his back, quietly not speaking. After a while, she whispered: "Criminal, are I too willful..."

"Why did you say that suddenly?" Li Xingzhou walked towards the courtyard with her back. The road was slightly cool, and the lanterns by the pool in the corridor were flashing brightly.

The clear moonlight shone down, illuminating Qiu'er's beautiful side face. In the pond beside the corridor, the moon fell in the water, accompanied by the sound of frogs, she whispered: "Because I spent a lot of money in the palace, but I couldn't make anything useful..."

She whispered: "I spent more money than General Manager Yan, more than Sister Shiyu, Ajiao, and Yue'er, and more delayed a lot of people..."

"Who told you?" Li Xingzhou asked.

"I thought of it myself."

"lie."

"I... accidentally heard what the maids in the mansion said, and they didn't dare to say it in front of me." Qiu'er said honestly.

Li Xingzhou entrusted her up and thought a lot in his heart: "They are talking nonsense."

"But what if the prince really just wants to make me happy? If the money I spent is useless in the end, then..." Qiu'er still wanted to say, but Li Xingzhou interrupted her: "The sage said, 'The heavens do not hate cold and stop winter, the earth does not hate vast and wide, and a gentleman does not have villains and stops even his career."

"But I am not a gentleman..." Qiu'er retorted in a low voice.

"The truth is the same, that's not for uselessness." Li Xingzhou smiled seriously and said, "You shouldn't think it's useless. The two are different. What's useful is the present, that is the future of the royal palace, the future of the country, and the future of the world. Those maids have no knowledge and just take one step at a time to see one step at a time. Qiu'er is not, Qiu'er is taking ten steps at a time to see one step at a time, isn't it?"

He said as he walked out of the corridor: "No matter what, just remember, I will always stand behind you, no matter what you do, don't think about messing around."

Qiu'er didn't say anything and hugged his neck tightly.

When she arrived at the gate of the courtyard, she quickly said with a blushing face: "Prince, let me go, they will laugh at me when they see it..."

Li Xingzhou laughed and put Qiu'er down. The little girl stood still and suddenly came up. The fragrance of the darkness came to her face, and then the corner of her mouth felt warm. When she came back to her senses, Qiu'er had already rushed into the yard.

Li Xingzhou touched the corner of his mouth, and the little girl kissed her...

He was not prepared to deal with his servants or make them shut up. This kind of paternalistic protection would only backfire. Qiuer must bear the weight, and he also believed Qiuer.

.........

The next day, August 14th, the streets were extremely lively, with people coming and going, shouting, bargaining, children crying, adults shouting, and full of life.

The court was over on the fifteenth day of August, but there was no one in the 14th day. Everyone in the palace also started to have a holiday from the fourteenth day. After Li Xingzhou went to court, he was pulled by Jiao and Yue'er and asked Qiu'er to go out to buy things. He took the lead to Zhenbao Pavilion and brought poems.

The closer the Mid-Autumn Festival is, the more lively it is. However, Li Xingzhou had already explained the poems that she would not have to ask about the business of Zhenbao Pavilion in person in the future. She is the one who has a look at the overall situation and should not be obsessed with the details, but she just can't stay idle.

In the end, he was reluctantly pulled away by Gillian and Yue'er.

When I go shopping with women, it is the same in any era. Men’s hell, let alone accompanying four women.

...........

After going down court, He Zhao left Changchun Hall. The sun was already rising. The warm autumn sun shone comfortably, but he couldn't be happy.

After cleaning up the west area of ​​the city, there is still a stench, and the people complain.

Moreover, the autumn rain was continuous a few days ago, and underground sewage was inclined to flood the streets. The people could not even have a good time in the Mid-Autumn Festival. Naturally, they kept petitioning the yamen. He made it difficult and had no choice.

Just when he was worried, he didn't pay attention to meeting the prince walking in front of him.

"Mr. He." The prince greeted,

He Zhaogong bowed: "The emperor has met the prince."

"You are polite. Lord He is in charge of Kaiyuan Prefecture for several years. The people live and work in peace and contentment. They have never had any major events that make the father worry about. They are really the pillars of the country." The prince flattered him.

He Zhao just bowed: "The prince praised it, but the subordinates did their duty."

"Mr. He is really modest, but looking at Master He's face, it seems that he is displeased?"

He Zhao thought for a while, but did not hide it, and said, "Your Highness, what I am worried about is the blockage of the underground waterways in the west of the city.

This incident has been accumulated for several years, especially this year's continuous rainfall has caused sewage to flood the west of the city. The people in the city are dissatisfied and the public is full of grievances. The officials are also bothered by this matter and cannot sleep or eat."

After saying that, He Zhao bowed again: "As the lord of the Eastern Palace, the prince must have the world in mind, the country in mind, and the people in mind. The subordinates beg the prince to say a few more words to the people in the capital in front of the emperor, and also help innocent people."

The prince looked embarrassed and quickly responded: "Of course, of course, as long as it is for the people, I have no choice...hahaha."

Then he changed the topic: "But I heard that Mr. He has a beloved daughter in his family. She is smart and generous, and she has not yet been betrothed. It just so happened that my eldest son Li Huan was not married, Mr. He..."

"Your Highness, the officials in this marriage dare not rush to the Tian family. Besides, the daughter in the family is still young." He Zhao quickly refused, then casually made excuses, and then hurriedly left.

The prince's face was gloomy and calm, and he cursed in a low voice: "Old man! How dare you not give me face! When I ascend the throne, you will be more beautiful than you!"

Then he rushed back to the East Palace in anger.
