People in Datang have been expelled from school

Chapter 478: Kong Yingda's Visit
The big dog sat down again wagging its tail, apparently calmed down.

The first trial of the fireworks was not very successful. After the magnesium was exploded by the high temperature of the gunpowder, the burned fireworks were very small, and there was a feeling that they could not be scattered, with only sporadic points.

However, since the test can be successfully released, the next step is to adjust the ratio of gunpowder to magnesium.

Think of Li Shimin's gift again.

One Shang, one respect, the meaning of which is already very clear.

Li Shimin likes obedient courtiers, and most of them say that the emperor likes obedient courtiers.

Especially capable and obedient courtiers.

Li Shimin wanted such a courtier.

Many people like to regard the word loyalty and filial piety as a sign.

Some people have even become foolish and loyal.

In his heart, Li Zheng didn't like people who completely entrusted their lives to an emperor.

Treat the emperor as someone more important than his own family?
A person can do everything for his family, for his relatives, parents and children, this is the most basic human nature.

As an emperor, he needs absolute loyalty from his subjects.

Even Xu Jingzong and Li Yifu, these two people have followed him for so long.

In fact, they also have Xiao Jiujiu in their hearts, and following themselves is only for the benefit of the two of them.

On the contrary, people like Li Yifu and Xu Jingzong lived very realistically and clearly.

After pouring himself a cup of tea, Li Zheng looked towards the eastern sky, waiting for the dawn of the next day.

Early the next morning, Li Tai got up early and went to court.

After breakfast, Li Zheng handed Dahu a list.

"According to what I wrote above, go and collect some."

Dui took a look at the items on the list and put them away.

"Don't use too much, and don't attract too much attention." Li Zheng warned.

"Understood." Dui turned over, got on a horse and left.

It was very windy in late autumn, and Li Zheng picked up a thick coat, which was a bit like the military coats of later generations, with mink fleece on the collar.

After boiling a pot of water and making a cup of hot tea, Li Zheng spread out the paper and began to outline the appearance of the fireworks tube.

Xu Hui came with the account book and saw Li Zheng sitting by the horse pen from a distance.

With a hair crown, Li Zheng looked much more energetic and dignified than before.

In the past, Li Zheng always wore a ponytail and his hair was not neat.

Now that he combed his hair, Li Zheng's face was much cleaner.

It looks so comfortable.

Some of the buns that were swayed casually still look like they used to be casual.

As the cold wind blew, Xu Hui realized that she had been looking at it for a long time.

A little blush flashed across her face, Xu Hui stepped forward in small steps and said, "Chang'an Ling, this is the account book for this month."

Recently, the business in Fangshi has been much less than before.

Li Zheng looked at the account book and nodded. Once the soap is out of novelty, it becomes a daily necessities.

Everyone will not buy in large quantities.

Although braised pork is the only one in Jingyangfang City, the business has not improved much compared to before.

Xu Hui said in a low voice: "Chang'an Ling, the little girl has an idea, I don't know if I should say it or not."

After taking a sip of tea, Li Zheng said, "Tell me first."

Xu Hui said: "Why not increase the number of shops? For example, go to another place to open one."

"You mean opening a branch?"

Xu Hui nodded, "It should mean branch."

"I don't have that idea yet."

After reading the account book, Li Zheng said to Xu Hui: "How does the new road in Jingyang compare with the old official road in Chang'an?"

Xu Hui thought for a while, "Now more and more people are taking our Jingyang New Road, but there are few people walking on the official road."

"Pay attention these days, how many merchants pass by our Jingyang."

"understood."

Seeing that Xu Hui hadn't left yet, Li Zheng put away his pen and said, "Is there anything else?"

Xu Hui said with some coyness: "Congratulations to Chang'an Ling Jiaguan as an adult."

After speaking, Xu Hui took the account book and left quickly.

"Why is this little girl acting weird today?" Li Zheng muttered.

After calming down again, looking at the design in front of me, I have seen the appearance of fireworks in later generations, but doing it by myself is another matter.

"Xu Hui is a good girl."

The abrupt voice startled the spirit, Li Zheng looked back and saw Li Jiangshan.

"Sister Killer, can you stop suddenly appearing behind me?" Li Zheng said.

"The queen asked me to bring you a message."

"Go ahead."

Li Zheng picked up his cup and took a sip of tea.

Li Jiangshan held the horizontal knife and said: "The queen asked someone to tell you that you should prepare early for the matter of marrying the princess."

Li Zheng wondered: "What else do I need to prepare for marrying the princess?"

As he said it, he thought in his heart that the business of buying and selling weapons gave Li Shimin more than [-] yuan a month, and his annual income was comparable to the annual tax of the Tang Dynasty.

"I don't know what to prepare, but that's what I said."

"that's it?"

Li Jiangshan nodded.

Li Zheng: "I have received the queen's words."

Glancing at Li Jiangshan again, Li Zheng said again: "Sister Killer, when did you come?"

Li Jiangshan said with a cool face: "When I came, Xu Hui was watching you over there."

Li Zheng glanced at the direction Li Jiangshan was looking at, and then glanced at Li Jiangshan strangely.

Li Jiangshan turned his head and said: "You look quite comfortable wearing a hair crown."

Li Zheng said melancholy: "Is there anything else for Sister Killer?"

"No."

"The killer sister, please go ahead."

Li Zheng continued to ponder the drawings of the fireworks, and the barrels of the fireworks needed to be firm.

The material of the gun barrel can be replaced by bamboo tube, which is the most trouble-free way.

Not long after Li Jiangshan left, Li Yifu came.

"Chang'an Order, old master Kong Yingda is here."

"Please come in."

Kong Yingda came to the stables, looked around and said, "I haven't been here for a long time, the changes in Jingyang are really upside down."

"Old Master Kong Yingda is a rare visitor, why do you have the time to come to my place today?"

Li Zheng enthusiastically poured Kong Yingda a cup of hot tea.

Kong Yingda smiled and said, "Yesterday you became an adult with the crown, and there were many affairs in the court and the old man didn't have time to congratulate you."

"Old Master, you were a great Confucian at that time, and you dare not let the Old Master care about you."

Looking at the drawing on the paper on the table, Kong Yingda asked curiously, "This is?"

"This is the blueprint."

"The blueprint?" Kong Yingda looked at it carefully, "Your blueprint is really novel."

"This is a new way of drawing drawings in our Jingyang." Li Zheng pointed to the dotted line on the drawing and said, "Look, this mark is the diameter, this is the radius, and this height."

Kong Yingda smiled bitterly, "Li Zheng, all your new knowledge is being given to your children in Jingyang."

"of course."

"And the science that teaches you to speak."

"Yes, there are some mathematics and physics."

"Apart from these?"
