The World of Yellow Sky

Taiye Pond, inside Yangxin Pavilion.

Xu An sat on the seat, and for the first time he knew what it was like to be on pins and needles.

Over the past few years, Yingtian Mansion has been continuously renovated, and now it has become the place where the three government departments and six ministries and hundreds of cabinet officials handle official affairs.
The Shiqu and Tianlu schools located in Yingtian Mansion were moved to the fringe areas, and Yingtian Mansion was no longer suitable for human habitation.

So his residence was also moved to the range of Taiye Pool.

Yan Zhong was ill before, so the Taiye Pool in the east of Yingtianfu became a sanatorium, and the medical school is also near the Taiye Pool.

Many new buildings were built in Taiye Pool, the sanatorium was in the south, and his residence was moved to the north.

Yangxin Pavilion is an attic in the backyard of his residence.

Seeing the curious looking fat man in front of him, Xu An was at a loss for a moment.

Wang Yi, who was still sitting on the side, spoke first.

"In the past, you always quarreled from time to time, asking where your father is."

Wang Yi smiled, bowed slightly, and pushed the little fat man towards Xu An who was sitting beside him.

"Now that your father is in front of you, why are you speechless?"

The little fat man in front of him is Xu An's son.

It's just that the world was changing at that time, and all his thoughts had to be devoted to the Han and Wei Dynasties.

The situation was weird and unpredictable, like walking on a single-plank bridge, if you were a little careless, you would be smashed to pieces, and there was no room for much attention.

Qingzhou changed dramatically, the Han army suddenly made a northern expedition, and the mountains and rain were about to come and the wind filled the building.

He didn't even come to get his name, and he led an army to the east shortly after he was born.

Now the little fat man's name was not really finalized until after the Battle of Fanyang.

The little fat man's name is Xu Feng.

The original meaning of "Feng" only refers to the prosperity of vegetation, and later it was extended to refer to a person's full body and plump appearance.

The first sentence of "The Book of Songs·Zheng Feng·Feng" is "The son's abundance is here, waiting for me."

However, Xu An named him "Feng", more because of the original meaning of the word "Feng", which means lush vegetation and abundant grains.

The world has been decided, and for Shengdou Xiaomin, there is nothing more joyful than a good harvest.

However, it seems that Xu Feng is now changing towards the second meaning of the word Feng, and his body is fat.

Calculating the time, the little fat man will be four years old this year. At this time, the year of birth is considered to be one year old.

He was almost one meter tall. At this time, he was wearing a red satin military uniform, his hair was not long, and he was neatly groomed. A pure white jade pendant and a wooden sword hung from his waist.

There was even a tassel hanging from the hilt of the wooden sword, wrapped with a rope, inserted in the scabbard in a decent manner, and hung on his waist.

However, Xu An keenly noticed that the little fat man's shoes were a little wet, and he probably got them from playing somewhere.

Children in the Han Dynasty did not tie or shave their hair, and their hair drooped naturally, so it was called drooping hair.

In some pictures of later generations, New Year pictures, some children appear with a small tuft of hair, and the surrounding hair is shaved off, which is not in line with Han etiquette.

How can the body, hair and skin be shaved off easily by the parents?
In this era, when they were children, only the nomadic tribes in the north, such as Xianbei and Wuhuan, had the tradition of shaving their hair.

The little fat man's eyes suddenly lit up, and then he bent down seriously, made a passable bow, and shouted.

"I have seen my father."

However, his head just lowered, and soon raised up.

The little fat man's eyes were still fixed on Xu An's body, a pair of shiny black eyes were gurgling, and he didn't know what he was thinking.

Xu An looked at the little fat man in front of him and couldn't help laughing.

He stretched out his hand and stroked the little fat man's head. The little fat man's hair, which was originally neatly arranged by him, was messed up a lot after he fiddled with it.

"A military uniform and a sword, he really looks like a young general."

Xu An picked up the little fat man and let him sit on his lap.

"The sword was given to me by Uncle Liu, and the uniform was made by Auntie."

The blood is connected, and there seems to be some kind of feeling in the dark. Xu An's actions did not make the little fat man feel uncomfortable. On the contrary, he felt that staying next to Xu An was very comfortable. Quickly replied.

"Do you like these things, or?"

Xu An's eyes moved slightly, and the Uncle Liu that the little fat man was talking about was naturally Liu Pi who stayed in Chang'an to supervise the country.

The little fat man was in high spirits, his voice was slightly high, and he was gesticulating with his hands.

"Uncle Liu said, Father is a hero and a man. My obedient book says that heroes and men both wear swords, so I want to wear a sword too!"

"When I grow up, I want to be like my father, to be a hero and a man!"

"Ambition, ambition!"

Xu An looked up to the sky and smiled. He originally thought that he had been fighting abroad all year round, which would delay Xu Feng's education, but he didn't expect that Xu Feng would have such ambition.

"Hahahahaha."

"Feng'er often goes to Shiqu College, and also heard those foreign students talking about current affairs in the pavilion, and some stories told by the lecturers, so they pestered me to keep asking."

Wang Yi's eyes were full of pampering, and he said helplessly.

"After I tell him about you, he will also wear a military uniform and a sword."

"I couldn't beg, so I changed a few clothes for him."

If a child wants to dance with a knife and a gun, ordinary parents, especially mothers, will strongly oppose it, after all, they are worried that the child will be injured.

But Wang Yi is obviously not an ordinary parent. She has been practicing martial arts since she was a child, and she likes to wield knives and guns.

Although she had a helpless expression on her face, she had no objection to Xu Feng's love of martial arts at all, otherwise she would not have changed Xu Feng's clothes with her own hands.

"Long time no see, your female workers have improved a lot."

Xu An laughed and joked.

Speaking of which, Wang Yi's female workers are actually not good, and they seldom sew any clothes.

The inner lining that Xu An is wearing now is sewn by Wang Yi, and it is an orphan in this world.

However, although the stitches are crooked and there are problems in many places, Xu An has always been wearing armor as long as he goes into battle.

A blush appeared on Wang Yi's fair face, and when he heard Xu An's teasing, he rolled his eyes lightly.

Although the two get together less and leave more, their relationship feels a little flat, but in fact it is very strong.

"Feng'er hasn't entered school yet, right?"

Xu An was playing with the wooden sword that was originally hanging on Xu Feng's waist, and asked at the same time.

"If you haven't entered school, it will take two years to meet the age limit before you can enter the Mongolian School. Even if you are admitted exceptionally, you will have to be five years old, and you are not old enough now."

Wang Yili smiled slightly, and replied in a clear voice.

The minimum age for admission to Meng Xuetang is six years old, and the threshold for exceptional admission is also five years old.

If you want to be admitted exceptionally, you must pass the interview of the interviewer, and a Meng school can only have ten places a year at most.

The benefit of exceptional admission is nothing more than entering school one year earlier.

In the current Taipingdao Academy system, outstanding students are allowed to skip grades one after another. There are age requirements for entering Meng Academy, but there is no age requirement for subsequent county studies or Chinese studies.

"However, when Lord Yan was here before, he was enlightened for Feng'er. Lord Yan taught him to speak and know how to read and write."

"After Yan Gong went to Qingzhou, he asked Yan Lun to teach Feng'er."

"Yan Lun..."

Xu An pondered for a moment, his impression of Yan Lun was already a little strange, but it wasn't that he had no impression at all.

Yan Lun is Yan Zhong's nephew. Because of his excellent handling of government affairs, he was later transferred to Taihang Workshop as the owner of the workshop.

Yan Lun is said to be one of the most outstanding young people in the younger generation of the Yan family. Not only has he read the entire book, he is also proficient in arithmetic and artisans.

Being able to become the owner of the Taihang Workshop relied more on his own ability, and the huge Taihang Workshop has never made any mistakes under his management.

After that, it perfectly completed the production task of the new harness, and the craftsmanship and production speed in all aspects were far superior to those of other workshops.

There were originally five workshops such as the Taihang Workshop, but under Yan Lun's management, the development of the Taihang Workshop was faster than other workshops, and the production speed was much faster.

Therefore, the Taihang workshop was also designated as the most important workshop, and the new research and laboratory were also set up in it, and Yan Lun was in charge of it.

Before Taihang Workshop was abolished, Yan Lun had always been the owner of Taihang Workshop.

After the abolition, Xu An transferred Yan Lun to Chang'an City as the owner of the new workshop.

Yan Lun is now in Chang'an City, and is the owner of the most special workshop among the ten workshops - the research workshop.

As the name suggests, the main task of this workshop is not to produce arms and ordnance, but mainly to research and study various things.

The steam engine and gunpowder, as well as the improvement of papermaking are all experimentally researched in this workshop.

The research workshop is right next to Yingtianfu and Taiye Pond, which is also guarded by yellow angels, and all researchers are given corresponding permissions according to their technology and responsibilities.

When they understand the technology to a certain level, they will no longer be able to live with ordinary people, and their personal freedom will be restricted to a certain extent.

The research workshop is very special, quite closed inside, and even has its own market and hospital.

This place is not under the jurisdiction of the Chang'an Governor's Department, nor is it under the jurisdiction of the Chang'an government. The person in charge of its security management is the Yellow Angel, and the research workshop is directly under the jurisdiction of the Taoist government. In other words, they are only responsible for Xu An.

After all, although the Dao government has government orders and divisions, in fact, the entire Taiping Dao today is Xu An's monopoly.

"Yan Lun, he is quite talented."

Xu An nodded slightly, thinking in his heart that the research workshop has made some progress in the research of steam engines, but the lack of airtight materials makes it impossible to make further progress. The fleet to search for rubber has not sailed yet, and the steam engine can only be put on hold temporarily. down.

The proportion of black powder has also been determined by the exhaustive method to determine the approximate optimal ratio, and the trial production of gunpowder weapons is beginning.

Now the focus of the research workshop is mainly on firearms.

The idea of ​​the hydraulic forging hammer was also brought up by Xu An before. After many experiments, the craftsmen in the research workshop have already launched a machine that uses hydraulic power, but it is still in the process of being perfected.

Important infrastructure materials such as cement are also in the scope of trial production, and the improvement of textile machines is also advancing steadily.

The invention of the spinning jenny triggered the first industrial revolution. Xu An naturally remembered that the change in productivity was due to the invention of those machines.

There are many ideas, but the technical difficulties are not easy to break through.

Xu An is not a professional researcher in this area, and he only has a half-knowledge about many things, and he doesn't even know the appearance of many things.

Ordinary people don't take the initiative to understand these things, and they only have a rough outline of them. How can they know all of them and understand the details and principles.

Unless you are a master of science and engineering, you still have a certain amount of research in miscellaneous subjects, and your practical ability is full.

It seems that many people come here as soon as they open their mouths. The ratio of gunpowder is one nitrate, two yellows and three charcoals.

But in fact, those people don't know that the so-called one nitrate, two yellow and three charcoal does not mean the ratio of 1:2:3.

One nitrate refers to one catty of potassium nitrate in the black powder configuration, two yellow refers to two liang of sulfur, and three charcoal refers to three liang of charcoal, which is not a simple 1:2:3.

And even for those who know the true meaning of one nitrate, two yellow and three charcoals, most people definitely don't know whether the "two" of two taels and three taels is calculated according to the ancient sixteen taels a catty, or Now count the current ten taels a catty.

And even if you have mastered all the theoretical knowledge, it is another matter to actually do it.

There are often practical classes in physics and chemistry classes in middle schools in later generations. Many students talk about the theory well, but in practice, they often make many mistakes, so that the experiment fails in the end.

"Yan Lun is currently in the research workshop?"

Xu An raised his eyebrows slightly, he suddenly had a whim.

Wang Yi frowned, her phoenix eyes glistened, how could she not know what Xu An was thinking, now that the world is peaceful, but she still can't take her time as a gentleman, she said helplessly.

"Today is not a holiday. The research workshop is naturally in operation. Now that I am riding a horse, the sun has not yet set. There should be someone on duty in the workshop."

Xu An was about to talk about going to the research workshop, but the conversation stopped at the end.

"It's too late today. The research workshop doesn't have any legs anyway, so I can't run away after all."

Xu An stood up, stretched out his left arm, and hugged the little fat man with one hand,

Wang Yi looked slightly surprised, and there was a bright wave in her phoenix eyes. She could see that Xu An really wanted to go to the research workshop at first, but she was surprised that Xu An actually changed his mind.

Xu An hugged the little fat man with one hand, and stretched out the other hand towards Wang Yi.

"There is no curfew in the past few days, and the east and west cities are brightly lit all night. It's a good time to see and see the grand scene of Chang'an."
