Considering the possible military adventure of defending the country after the financial turmoil, Bailiyan ordered the artillery workshop to increase molds and sand molds, and increase the production of platinum-based copper-nickel-iron-based alloy guns at any time in case of emergency.

Despite the fact that a platinum-based copper-nickel-iron-based alloy with excellent performance was obtained, trouble continued.

The performance of this alloy and related production technology are too advanced, and the related supporting equipment and technology cannot keep up, especially the lack of core process equipment such as large-scale forging presses, holding furnaces, heat treatment, and cranes, which makes the alloy steel unable to be kept warm and heat treated in time after pouring and forming, resulting in brittle steel after casting and molding, and the performance is greatly reduced.

In order to solve this problem, Yongxing City and the Gonggong team spent half a year and nearly 400,000 Singapore dollars to use the coal pile dewarming method to make the material meet the usable requirements.

This method buries the artillery sand mold under the ground in advance, the sand mold is buried around the sand and is fixed, and then the coarse coal is buried around the sand, and the coarse coal is poured with fuel oil to ignite and heat, and finally the alloy iron is poured into the artillery sand mold to be poured into it and waiting for solidification.

The solidified molten iron is always in a red-hot state under the continuous heating of the peripheral coal, and then waits for the coal to burn out, and finally waits for the artillery to cool down naturally.

At this point, the artillery material has been insulated and basically heat-treated, so that the alloy steel meets the required technical requirements.

The whole dewarming cycle lasts for one month, and it takes a long time to prepare and dig the dewarming pit in advance. Although thankless, the reward is still very cost-effective relative to the effort

In view of the shortage of land for the construction of a large number of smelting and coking workshops in Xicheng, Su Hong proposed to expand Yongxing City to accommodate more factories. Bailiyan considered building a new city south of Yongxing City, upstream of the Yongxing River, and downstream of Wuping.

First, after nearly 20 years of development, Yongxing City is developing from a mixed city to heavy industry, and the secrecy of core industrial technology restricts the migration of factories at will, so the city wall will always be an important obstacle to restricting the land in the city, but without the city wall, it is obviously not possible at the moment.

Second, the land in Yongxing Dongcheng is also very tight, a large amount of land is occupied by housing, private houses, schools, military camps, lecture halls, Yicaotang and the main hall of the Ligong faction, and the land available for the newly built machinery factories and technical departments is very limited, so it is necessary to move away from core educational, residential and non-industrial institutions, and evacuate part of the high-quality population.

It is the general trend to build a new city in the south of Yongxing, located between Wuping, Ruitian and Yongxing, and to move away the mature and high-quality educational resources and prepare for the construction of education, scientific research and technology centers. In addition, as a medical and biopharmaceutical research department, it is not the same thing to open in an industrial pollution center, and it is better to move away sooner or later, and it is better to move early than later.

Yongxing stayed until the third day, and the king of Xian sent people to urge, the reason was that Mooney led the delegation north into the Central Plains, and the national letter of the Jin Xuedi people was transmitted to the tomb through the royal guest.

The intention is very clear, and the purchase of medicinal materials is open to trade.

Bailiyan pondered, most likely because King Xian saw the money again, stared at Jin Xuedi's money bag, and waited for the pie to fall from the sky.

After several days of fermentation, the news of the shortage of gold and silver is spreading from the cabinet to the foreign courts and the magnates, and from the power stratum to the society, and the situation is about to become even more severe.

Just after arriving at the Hou Mansion, there was a jujube red horse tied to the horse stake outside the wall on the right side of the door, and several guards of the Inner Palace Forbidden Army stood on the left and right, which was extremely powerful, and Bai Liyan recognized at a glance that this horse was the mount of Jiang Can, the youngest son of King Xian.

At present, there are more than 60,000 horses in the southern border, and more than 4,000 horses in the Xianguo country are used to transmit news and rewards, and they are forbidden to be sold.

However, the theft of horses and the stealing of breeding have been repeatedly prohibited, in order to keep the horse breed from being stolen, Bailiyan is equipped with an important contraceptive and fed to the domestic health BMW. This drug has few side effects, has a long expiration date, and is very effective.

Jianbao has also found some of its unique points after a long time, this kind of horse is not easy to be irritable during estrus, not easy to be frightened, has strong adaptability to artillery roar, and once tamed, it is dependent on people.

In addition, the sense of smell is very sensitive, stronger than that of other horse breeds, and even stronger than some dogs. The only drawback is that it consumes food, and everything else is stronger, but this is unacceptable.

As soon as I entered the house, the sound of women frolicking was endless, Baili Yan followed the sound to the verandah of the middle courtyard, Xiao Chunyu, Chunrou, and Chunfang sat under the pavilion chatting and laughing, and the children and Jiang Can were playing in the courtyard, without the distance between men and women.

Bai Liyan's family rules have been relaxed a little over the years, and if she wants to see Lord Qiao back then, she has to come out after a long time, how can she let her daughter show up so easily now, and if she spreads it, it will be immoral at best, and at worst, she will have to bear some bad reputation that is not human.

Baili Yan came quietly, the women didn't notice, Xu Bu came to the courtyard, he coughed lightly and said:

"Ahem......"

Xiao Chunyu's three daughters looked overjoyed:

"Master Hou."

Xiao Chunyu stood up, followed by Chunrou and Chunfang.

"Master Hou came back early today." Xiao Chunyu whispered when she heard it, and every time she listened to it, it made people feel like their hearts were about to melt.

"It's so lively today, and the son of the world is also here." Bai Liyan looked at Jiang Can and the others, but they didn't seem to notice the strangeness in the courtyard, and they talked and laughed with the women of Bai Li Xuan.

At this time, Chunrou said:

"The school is on holiday today, and the prince came early in the morning, and it has been until now."

"Oh, I remember, today is the middle of the month, and the school is on holiday."

Sheng Yuan 641 years ago, the school is open every month, every day according to the class time, due to the small content, Erlang School and Juvenile School, basically in the morning, basically out of school in the afternoon.

After 641 years of Shengyuan, all schools adjusted their work and rest, with three days off in the middle of each month and three days off at the end of the month, for a total of six days. There is no winter and summer vacation, only a month off in the first month, classes throughout the year, and today's return to home is just in time for the holiday.

When I was young, the atmosphere in the courtyard changed greatly, and the sharp-eyed children were busy saying:

"Father is back, Brother Chan is going to be unlucky......

It was the ten-year-old Baili Barbarian who spoke, and his tone was quite similar to Tang Tao. Jiang Can was shocked when he heard the news:

"Ha, it's Yongxinghou, it's broken!"

Jiang Can's face changed greatly, he hurriedly put away the smug look just now, looked back and was about to talk to Bai Li Xuan, but suddenly saw Bai Li Xuan and the maid Wei Ningning disappeared. Jiang Can's heart was even more anxious, so he hurriedly dressed up, and stepped forward in a panic to salute:

"Jiang Can has seen Yongxing Hou."

"The prince, please excuse me."

Jiang Can hurriedly accepted the gifts, and then said:

"I don't know if the Marquis of Yongxing returned home, Jiang Can came rashly and rude."

"Hehe, the prince is serious. It's normal for people to go door-to-door, and it's good to walk around more. But you can't always go to the mansion of the Hou, the prince should go to the people more, and knowing more about the people's sufferings is the right way.

At present, although the Xianguo territory is safe, the new land is still dilapidated, and the prince must not be blinded by the wealth of the capital. ”

What Yongxing Hou said, Jiang Can kept it in mind. However, now that the schoolwork is not finished, my father will not let me enter the court, and Jiang Can is also powerless. ”

Jiang Can's eighteen this year, six years to advance the aristocratic Erlang School, because of its good foundation, literacy and literacy, Erlang School only studied in a hurry for two years, and then promoted to the aristocratic juvenile school, two years into the middle school, this year is the third year of middle school.

The aristocratic middle school course has one year longer than the ordinary middle school course, and simple economic and statecraft courses have been added to cultivate the basic understanding of the aristocratic class on governing the country, and the state apparatus cannot be blindly turned into a tool for pure profit, and the people at the bottom are disregarded for life and death.

Jiang Can's grades have always been among the best, and he is outstanding in both exams and theory, but his personality is prodigal and loose, and he has no ideals, and it is reluctant for him to bear the burden of a country.

At this time, the women came forward, and Bailiyan looked left and right and found that Bailifang, Bailixiang, Baili Caiyun, Bailixuan, and Bailiwan were missing

Baili Fang probably didn't know where to go again, Thyme and Baili Caiyun are sixteen, and today is a holiday, so they must have been called by Jiang Rong and Qiao County Lord to go to the department store to help take care of it.

Baili Xuan doesn't like to see people on weekdays, inherits Xiao Chunyu's good character, lives in the boudoir on weekdays, fiddles with some piano, chess, calligraphy and painting, and has been extremely close to Jiang Can since childhood.

As for Bai Liwan, although she was less than five years old, Zhou Kong was not allowed to be idle at all, and most of them were caught by Zhou Kong in the backyard to preach at this time. The rest of the girls are still young, and they usually play together, but they are also harmonious.

Sending Xiao Chunyu, Chunrou, and Chunfang to take their daughters away, Bailiyan and Jiang Can said earnestly:

"Although the prince has not reached the crown this year, but the current situation is turbulent, the prince, as the prince of Xian, should take on the responsibility of the country, and must not let go of the wreckage and disappoint your father."

"But I'm really not interested in politics at all." Jiang Can said bluntly, and said: "The other brothers are all sharing their father's worries, one more than me, no more than me, no less me, what's the matter." ”

"Everyone has their own ambitions, and this marquis will not embarrass His Royal Highness, but the prince is a prince, and he has to do what he can for the country. You can't do nothing, just to be a mediocre person who has children. ”

"Then what does Yongxing Hou think this son can do?"

Jiang Can asked solemnly, Bai Liyan thought for a moment and said:

"What do the sons like besides money, women, famous horses, and sailing?"

Hearing the word "woman", Jiang Can immediately blushed and said:

"That's a lot, I heard that an observatory has been built on Miaotian Mountain, and the telescope is so big. I also heard that in recent years, Yicaotang's medical skills have been superb, and I want to study medicine again, but I think the artillery is very powerful, and there are too many things I like to say, and I don't know how to choose in this life. ”

"Then let's go and study medicine. If a person can do a good job in his life, he is worthy of his heart. If you do two things well, that is called success. Do three or more things well, that's great. The study of medicine is not only the art of hanging the pot to help the world, but also the suffering of the world.

If a man does not know suffering, he does not know what sweetness is. His Royal Highness the Prince was born in the palace, and he doesn't know the time and suffering, and studying medicine can be regarded as a practice of knowing hardships, what does His Royal Highness the Prince think? ”

"Okay, when can I go to Yongxing to study medicine?"

"When His Royal Highness finishes his studies this year, he will first complete one year of study in the palace medical officer's office, and then go to Yongxing to study medicine in two years."
