The eunuch was invited to the king of Hejian County.

Li Xiaogong, the king of Hejian County, walked into the hall and saluted Li Shimin, "Your Majesty." ”

Li Shimin said to the eunuch on the side: "Serve tea to the king of Hejian County and brew it with tea leaves." ”

Put a few tea leaves in a porcelain bowl and pour boiling water.

Since the Midyear Festival, His Majesty has inexplicably liked this way of drinking fried tea and water.

Li Xiaogong carefully took the tea bowl, the aroma of the tea was very good, took a small sip, and savored it.

Li Shimin finally stopped writing, raised his eyes and said: "Those guys from the Imperial Medical Department said that drinking alcohol all day is not good for the body, but it is better to drink tea occasionally. ”

"Thank you, Your Majesty for tea." Li Xiao bowed respectfully, constantly pondering the voiceover of these words in his heart.

Li Shimin stood up and said, "I heard that the group of envoys from the post house last night were making trouble again. ”

Li Xiaogong bowed his head and waited for Li Shimin's next sentence.

The hall was quiet for a long time, and the voice came again.

"Now that the DPRK and China are employing people, Fang Xuanling and they all wear many hats, and they can't get rid of them, and the affairs of the post house envoy are supposed to be taken care of by the Ministry of Rites."

Sighing again, Li Shimin said worriedly, "Those old guys in the Ministry of Rites were all people who followed their father back then, they only talked about etiquette, they only talked about the way of a gentleman, and they couldn't suppress the envoys, and the people of the Central Plains knew the way of a gentleman." But those outsiders have never read the books of the Central Plains. ”

Seeing that Li Shimin was about to talk about the Ministry of Rites, Li Xiaogong hurriedly cleared his throat, "Your Majesty, in fact, the minister has not read for a few years. ”

"What? As soon as I talk about the Ministry of Rites, you push and procrastinate, we have a few brothers, only you can see it a little more pleasantly. Li Shimin said distressedly: "Those old guys in the Ministry of Rites can't suppress those people from the Western Regions. ”

Li Xiaogong let out a long sigh, "If Your Majesty has a will, the minister will definitely receive the order!" Go to the soup and go to the fire. ”

Li Shimin waved his hand and said, "You can go to the Ministry of Rites to take up your post now, the position of the secretary of the Ministry of Rites has been vacant for so long." ”

"The minister commands."

After saying that, Li Xiaogong left the Ministry of Rites.

Li Shimin sat down again, looking at these recitals in front of him and was distraught, there was a shortage of people, there was a shortage of people in the court today, Li Xiaogong was a rough man, didn't he know how many words he knew?

It's not because there are no trustworthy people.

Li Shimin was in a bad mood and asked, "What is Qingque doing these days?" ”

The eunuch replied, "His Royal Highness King Wei has been going to Guozi every day these days to listen to the class. ”

Hearing this, Li Shimin felt a little more comfortable, and there was a shortage of talents at the moment, especially young talents who could be cultivated.

When Li Xiaogong arrived at the Ministry of Rites, he took over the reception of envoys from various countries, and unexpectedly found that the recent affairs between the envoys were related to a Japanese monk.

Listening to the officers and soldiers of the post house, Li Xiaogong said suspiciously: "This thing is too strange. ”

Li Xiaogong took over the affairs of the Ministry of Rites, and also had to deal with the contradictions between the countries, and in another month, the envoys of various countries would enter the court and pay tribute, and they still needed to prepare at the moment, not to mention the other six ministries in the court.

I also have to deal with those old guys in the court.

The affairs of the clan were also sent to the Ministry of Rites, and things were piled up in front of him, Li Xiaogong was a head or two, decadently sitting in the Ministry of Rites, homesick, wanting to go back to his hometown, returning to his hometown to farm, and he didn't want to do it.

The New Year is approaching, and Chang'an City is still cloudy today, and it looks like it will continue to snow.

Pedestrians on the streets hastened their pace home.

Zhang Yang went to the market again to buy some meat and vegetables and came back.

Li Yue was making Kong Ming lanterns in the courtyard.

This time, the specifications of the Kong Ming lantern are much larger.

There were still some stones hanging under the lamp, and the heart said that the little daughter-in-law was still thinking about the hot air balloon.

Li Yue took his small notebook, "I calculated a few important factors that made Kong Ming Lantern fly with things. ”

Zhang Yang put sulfur, saltpeter, rosin and other things in the corner of the courtyard wall, and began to wash the meat and vegetables to prepare for cooking, listening to Li Yue talk.

Zhang Yangdian continued to wash the vegetables and said, "I bought fresh duck blood today and some offal, which can be used to make soup." ”

Li Yue lit the Kong Ming lantern, and watched the Kong Ming lantern fly higher and higher, flying towards the distance.

Treat the duck blood, and when it coagulates, you can cook and eat.

It's great that the little daughter-in-law doesn't come to the kitchen, light a fire, wash the pot and cut vegetables in one go.

was stir-frying, Zhang Yang felt a pair of resentful eyes looking at him.

The movement of the spatula in his hand did not stop.

The resentful eyes were a little closer.

Zhang glanced at Li Yue, looked at her a little aggrieved and asked, "What's wrong?" ”

Li Yue said: "I have a question for you. ”

"Say."

Li Yue frowned and said, "If the Kong Ming lantern is bigger, the weight will be greater, and the greater the gravity, isn't this counterproductive?" ”

"It seems like that's the case."

"Is there a way to crack that?"

"I don't know."

Hearing the reply, Li Yue stood in place with her mouth pursed, looked at Zhang Yang's expression for a while, and stomped her little feet and walked back to the house.

Zhang Yang tasted the taste of duck blood soup, "Well, it's not salty enough." ”

With the meal, Li Yue was already sitting at the dinner table with a depressed face.

Put bowls of food on the table, and say in my heart that those formulas and theorems appeared in the annals of history in advance, and Datang's mathematics and science were a thousand years ahead?

And it is also the achievement of his own daughter-in-law.

The seniors in the textbooks don't blame me?

Li Yue looked at it and said, "Why do you look weak-hearted." ”

Zhang Yang sighed: "I don't know what's going on lately, and I always feel uneasy about my conscience." ”

Li Yue sat upright with a solemn expression, "The greater the weight, the greater the gravity?" Isn't this an endless loop that can't be broken? It is impossible for Kong Ming Lantern to take people to the sky. ”

Zhang Yang said with emotion: "It's amazing to be able to find this." ”

"It's amazing...... Li Yue muttered in a low voice, her little face turned black and glared at me with anger: "Are you deliberately angry with me?" ”

Life between husband and wife will not always be peaceful, there will always be a bit of twists and turns.

Quarrels are inevitable.

Zhang Yang picked up the rice bowl and saw that she hadn't moved her chopsticks yet, so he said: "Why don't you think about changing some structures, changing the influence of these constants by changing the structure." ”

Hearing this, Li Yue was stunned.

"Gravity is a fixed constant, and we can only start from the material of Kong Ming lanterns, and we must increase the area affected by heat to determine the utilization rate of combustion."

The research direction is correct, and the little daughter-in-law can go from doing theoretical problems to practicing and inventing.

Zhang Yang said in a low voice: "This progress is really one day at a time, and it is too fast to master, it is really incredible." ”

Li Yue's expression finally swept away the previous haze, and he smiled playfully and ate the meal in front of him.

While eating, I saw an old couple passing by in front of their courtyard.

The door is deserted, and there are hardly any pedestrians to be seen on weekdays.

Today, a living person passed by his door......
