Chang'an City finally welcomed its owner after nearly a month.

Li Shimin, who had been walking around Liangzhou and stayed in the grassland for a few days, then followed the cement road from Liangzhou to Fuqi City and walked to the young Qinghai Road for more than ten days, and then returned to Chang'an City with satisfaction.

"Your Majesty, you're finally back!"

In the Chu King's Mansion, when Li Kuan appeared in everyone's eyes again, everyone felt that life was coming.

When Li Kuan was away, whether it was Cheng Jingwen or Wu Meiniang, he felt that life was missing something.

Now this feeling has finally been recovered.

"Jingwen, Meiniang, thank you for your hard work during this period! I already know the matter of the money house. You have handled it very well! There is nothing to be polite to deal with the Changsun family!"

Li Kuan, regardless of the maids around Qing'er, sat beside him with one hand and held Cheng Jingwen and Wu Meiniang.

"This time, the Changsun family did not get a good deal. Not only did the money house that had been operating for several years completely disappeared, but they also lost a lot of money. It would not be so easy for them to build a money house again in the future."

Although there were a lot of worries in the middle, the result was perfect, so Cheng Jingwen was not talking like Xianglin Sao.

"The Changsun family is jealous of the annual profits of the Tang Dynasty Royal Money House. If we want to make more money, we will let them develop in the opposite direction. Their iron smelting workshops are no longer profitable. If it weren't for the fact that the development of their iron smelting workshops still had some significance to our Tang Dynasty, they would have killed it.

Iron smelting does not make money, money houses have no money to make, and the most profitable thing left is the trade between the grassland and overseas. On the other side of the grassland, if the Northwest trade is put into force, it is a problem for the Changsun family to walk safely on the grassland. As for the sea trade... Haha, if the Changsun family is willing to keep buying ships and accept the ending of the missing ships, then let them do it.

Without these profitable industries, the Changsun family's property will soon be surpassed by other nobles. Now they are still decent, namely the cotton fields in Hedong Road and the newly opened sugarcane garden in Lingnan."

Changsun Chong and his men caused such a thing when Li Kuan left Chang'an City. Even if they were finally hit and bloody, the Chu Prince's Mansion was the winner, and Li Kuan had no intention of just turning things over just like this.

If this is true, I guess the cat and dog will think of challenging the Chu Palace in the future.

"The prince, the cultivation of cotton and sugarcane is related to the grassland plan and the development of Lingnan Road. Let the Changsun family survive in these two fields for a few years."

Cheng Jingwen was afraid that Li Kuan would attack the Changsun family in order to avenge her, but this was not the result she wanted to see.

"I heard that the Changsun family has begun to focus on Shuozhou during this period. Their cotton workshops seem to be updating equipment, which seems to be mysterious and mysterious. It's very much. I'm worried that they don't give up and want to make any more trouble on the cotton."

Wu Meiniang obviously has more resentment towards the Changsun family than Cheng Jingwen.

Wu Meiniang is mainly responsible for the business affairs of the King of Chu Mansion, and Cheng Jingwen doesn’t ask much about it.

The Changsun family started to deal with the Chu Prince's Mansion from business, but in fact it was dealing with Wu Meiniang. Can she not be angry?

"The soldiers come and the generals stop them, and the water comes and the soil covers them. This time, we will completely cut off the profits that the Changsun family has obtained from the grassland and overseas trade, so that they can feel the pain deeply."

It is better to cut one finger than to hurt one finger!

Li Kuan felt that he needed to think carefully about how to deal with the Changsun family!

Not to mention the information I received from Yin Fei, the Changsun family could not spare them just because they were unable to get along with him repeatedly.

In the past, Li Kuan would have left some effort to deal with the Changsun family for the sake of Empress Changsun.

There is no need now!

"Prince, although we completely destroyed the Weishui Money House that was causing trouble this time, the future deposit rules of the Tang Dynasty Royal Money House may have to change."

Although I felt a little sorry for the loss, Wu Meiniang knew very well what to do with the Tang Dynasty Royal Money House at this time.

"Well, the specific plan, Mei Niang, please arrange someone to make it. After I have read it, let the Tang Dynasty Royal Money Bank update the deposit rules. This time I also mentioned the development of the Tang Dynasty financial industry with His Majesty. At that time, the court will authorize the Tang Dynasty Royal Money Bank to manage other money banks and formulate a series of rules for the development of the entire financial industry.

In the future, if other nobles want to set up money houses, they must obtain the dual approval of the Ministry of Revenue and the Tang Dynasty Royal Money Bank; then all money houses must transfer 20% of the money deposited by the depositors into the warehouse of the Tang Dynasty Royal Money Bank, so as not to borrow all the money of the depositors, and once there is a risk, it will cause chaos to Chang'an City."

Li Kuan also told Wu Meiniang about the matter he discussed with Li Shimin.

It can be said that taking this opportunity, the Tang Dynasty Royal Money Bank has completely settled as the number one in the Tang Dynasty's financial industry.

Afterwards, Li Kuan told Cheng Jingwen and Wu Meiniang about something else. He originally thought that he would be better than a new marriage than a new marriage and would have a big sleep together.

However, ideals are full, reality is skinny.

"Prince, it will be Xiao Yumi's sixth birthday soon. She has been asking you when you will be back, fearing that you won't be able to catch up with her birthday. At that time, do you want to prepare a special birthday gift for her?"

After a regular exercise, Cheng Jingwen lay weakly in Li Kuan's arms and said things softly.

"A birthday gift... I'm really thinking about it."

Li Kuan found that he was a little afraid of his birthday and had a headache every time he had gifts.

Although he can also prepare a gift for him at will, Qing'er can definitely prepare a gift that meets the expectations of society.

However, for his close relatives, this method was not what Li Kuan wanted to use.

So every time Li Kuan celebrates his birthday, whether it is Cheng Jingwen, Wu Meiniang, or a few children, he will have a headache.

Fortunately, there are only three children now. If there are too many children, I will have a headache every month and prepare some birthday gifts.

"Little Yumi likes strange things the most. She likes things that others don't have, but only what she has. If you don't know what to prepare, you can ask the mechanical workshop of Guanshishan Academy to make a model for her."

No one knows a girl better than a mother!

Although Xiao Yumi has a weird personality, Cheng Jingwen, the mother, actually knows her very well.

"Let me think about it~"

While playing with the softness in his hands, Li Kuan was thinking about what the most common birthday gift in later generations was.

Bag?

Although there is a saying that "treats all diseases", Xiao corn obviously will not be interested.

Perfumes and cosmetics?

I can make some very special ones myself, but Xiao Mei is only six years old...

Children's toys?

Precocious little corn is not interested in toys played with by ordinary children.

watch……

Li Kuan suddenly stopped the movement in his hand, "Yes, I know what gift to prepare. I will go to the watch workshop tomorrow to meet Lang Qing and ask him to prepare a product according to my requirements."

"Prince, although clocks are very good gifts, it doesn't make any sense to give to Xiao Mei, right? We have already placed clocks in many rooms in our mansion."

Cheng Jingwen was obviously not very satisfied with the gift Li Kuan planned to prepare.

"Don't worry, I understand what you said. When will I ever feel dissatisfied with you?"

Li Kuan said in a pun, then turned around and continued to work hard.

...

Below Guanshishan Academy, there is a watch research institute, whose director is Lang Qing.

Since inventing Big Ben, Lang Qing has gained fame and fortune. Not only has he obtained shares in the watch workshop, he was also appointed as a teacher by Guanshishan Academy of Gewu Academy and also served as the director of the Watch Research Institute.

In recent years, the clocks produced in the watch workshop of the King of Chu Mansion have been improved and have become a must-have item for wealthy merchants.

The stable development of the clock has driven the development of the entire industry.

The workshops in the King of Chu Mansion have begun to abandon the practice of doing everything by themselves. According to the principle of leaving professional things to professionals to do, the parts of the clock are allocated to various workshops for production.

Some of these workshops are subordinate to the King of Chu Mansion itself, but more are other workshops in the workshop city that have no shares with the King of Chu Mansion.

For example, the gears inside the clock were made by Jintai Iron Making Workshop, while the springs were produced by Water Alloy, and the screws used inside were produced by Changan Seiko.

Since Lang Qing was once a student of Guanshishan Academy and is now also a teacher of Guanshishan Academy, the clock he involved was a part supplier and prefers to choose workshops created by students of Guanshishan Academy.

For example, Shui Jun, the founder of Shui Jun Production, performed mediocrely in the academy and had no choice but to compare with geniuses, but his father Shui Ergui, as the largest peach grower in Mitao Village, supported him in starting a business because of his wealth.

However, the unremarkable water jungle in the college, the water jungle production institute we created focuses on the supply of parts in emerging industries, and the various springs we research are very popular. Water jungle has even specially developed a special spring processing equipment. After the scale of the production institute increases in the future, we are planning to study spring steel separately.

And that Chang'an Precision was also founded by Chen Xing, the first student of the Calculation College of Guanshishan Academy.

As the first student to start a business in the School of Calculation, Chen Xing has a good relationship with Liu Yuan, Liu Jie and even Xu Jingzong, and he has a wide connection.

However, he chose screw nut, a very inconspicuous part, as an intervention point for entrepreneurship, and from the beginning to the end, he only studied this type of part.

Of course, this has something to do with Chen Xing's graduation thesis.

Chen Xing, from the School of Calculation, studied the mystery of thread curves, and was successfully published in the journal Science. He also applied for patents on several special thread structures and thread processing techniques from the Royal Patent Office of the Tang Dynasty.

Nowadays, thanks to the rapid development of new workshops such as Mercedes-Benz four-wheeled carriage workshops, permanent bicycle workshops, as well as Langqing Watch Workshops, the demand for screws, bolts and nuts is increasing day by day. This workshop with less than 100 craftsmen is also booming now.

"His Royal Highness, the structure of this timing mechanism is not complicated. Although the layout is much more exquisite, it is still the same as the clock. The main question is whether it can be produced is whether these components can be made. I think several shopkeepers from the relevant workshops may need to be called over to discuss it before further judgment."

In the Watch Institute of Guanshishan Academy, Lang Qing stood respectfully in front of Li Kuan and explained in a schematic diagram.

In order to surprise Xiao Yumi, Li Kuan thought of the once popular pocket watch.

As a product that goes from a clock to a watch, the historical significance of pocket watches cannot be ignored.

Its appearance allows people to finally carry their timing tools with them.

The popularization of timing tools will further promote the development of science and technology and contribute to precise scientific research.

At that time, Li Kuan forced the promotion of length measurement units, weight measurement units, time measurement units, and volume measurement units in Guanshishan Academy, which were all essential preparations for scientific development.

A systematic unit of measurement is definitely an indispensable part of scientific development.

Otherwise, everyone makes different things, everyone's research results are different, and scientific achievements are not replicable at all, so it is too difficult for science and technology to develop.

"Which workshop, watch cover, gear, bracelet, screw, watch needle, which workshop you think can be produced, let their shopkeeper come here immediately, and everyone thinks about it together and take out a sample of a pocket watch as soon as possible."

Generally speaking, Li Kuan will no longer ask who the supplier of each product is, nor will he spend too much energy to guide the technical improvement of a specific workshop.

Unless it is encountered that can improve the overall industrial level of the Tang Dynasty, he has rarely done anything to encourage growth.

Otherwise, Li Yan would not have to work hard in the Steam Engine Research Institute of Guanshishan Academy for several years but had not yet come up with a decent work.

"It is better to use cooked food than raw. I think this pocket watch should be just for the suppliers of the current clock to try making it. It mainly involves the glass workshop of the King of Chu Mansion, Jintai Iron Workshop, Water Jun Workshop, Chang'an Precision Workshop and other workshops. I immediately arranged someone to inform their shopkeepers to come."

"I'll give you five days. No matter what process you use or the processing cost, you must take out a sample within five days. I'll be of great use when the time comes."

Unless Lang Qing and the others can't handle it and take the initiative to ask Li Kuan for guidance, Li Kuan is willing to be a hand-off manager.
