Bauxite is now mainly used as an additive for building city walls, firing city bricks, and as a food additive. Although Xianguo is a big country in jade processing, there are very few jade mines, and they are mainly imported from Changsun Kingdom.

It is not surprising that bauxite appears in the Bengfu jade mine, and jade is, in a sense, an oxide of aluminum, and when bauxite cannot be converted into jade, bauxite and other aluminium compounds are naturally formed.

Bauxite is divided into metallurgy, chemical industry, refractory, grinding, cement and other uses in modern industry due to its difference in content and composition. It is an important industrial raw material for refining pure aluminum, making grinding wheels and refractory high-alumina bricks.

At present, a small number of laboratory samples can be prepared by chemical means, but there are no technical conditions for large-scale industrial production of pure aluminum, but bauxite can be used to manufacture grinding wheels, plane grinding tools, and high-grade refractory high-alumina bricks, which are used to build blast furnaces with larger tonnage, so as to improve steelmaking capacity and provide technology and experience reserves for the future construction of converter steelmaking

If the effect of the holding furnace can be improved, the thermal energy efficiency will be increased, the utilization rate of coke will be higher, and the furnace temperature will be increased to smelt metals with higher melting points.

As he spoke, Jiang Jie came on horseback and interrupted the conversation by entering the room:

"My lord, the eldest lady is here."

"What is she going to do with a big belly?"

"The eldest lady told the lord to return to the mansion quickly."

"Got it."

With Jiang Jie back to the office, three carriages were quietly parked outside the mansion, and Bai Liyan recognized two of them at a glance as carriages from the Xuanting Marquis Mansion.

When they came to the backyard, Jiang Rong, Princess Lanyuan's mother and daughter, and Xuantinghou's father and son were already waiting in the inner house.

"Wei has missed the distance, and I hope that Lord Hou and Mrs. Hou will forgive me."

At this time, Lan Yuan stood up and took a step forward and said:

"Doctor Wei, hurry up and excuse me."

"Mrs. Hou came here late at night, I don't know what is important?"

"This is a lifelong event for the little girl." Saying that, Lan Yuan called his daughter: "Fu'er can't come yet." ”

"Yes, Mother."

Jiang Rong also had a big belly at this time, stepped forward, and pulled Bailiyan to the corner of the house and said:

"It happened suddenly, and I didn't have time to discuss it with you."

"Discuss with me what?" Bai Liyan wondered.

"It's too late to get married, so I want to leave you a seed."

Bai Liyan was dizzy when she heard the news, and hurriedly asked:

"Leave a seed? As for being so pessimistic? ”

"Do you think I'm willing, do you understand that the department store is making money every day."

"What do I know?"

Jiang Rong frowned tightly, looking depressed:

"Why don't you understand, if you have a seed, won't you be able to split up?"

"Split!" Bai Liyan was taken aback: "Who said that they were going to split up!" ”

Jiang Rong poked Bai Liyan with her elbow, and pointed back at Xuan Tinghou and his monkey spirit son, Bai Liyan glanced back, only to see that the eyes of the father and son were particularly abnormal, which was diametrically opposed to Princess Lan Yuan's faint sad look.

Seeing this, Bai Liyan suddenly understood.

Xuanting Hou Bacheng is suspicious that Baili Yan's southern expedition is going and not returning, the huge family business of Wei Mansion will definitely be a golden rice bowl covered by King Xian in the future, not to mention the capital flow of the department store for a year, the ability to catch up with the savings of Xuanting Hou Mansion for seven or eight years, how to turn the technical intellectual property rights of Wei Mansion into a profit-making tool of Xuanting Hou Mansion is obviously an important issue.

But the lord of Xuanting County has not passed the door, it has become a thorny problem, but now it is definitely too late to organize a wedding, so simply come to the door first, cook the raw rice and rice, if there is a case in the future, Bailiyan will pass the door justifiably. The Wei Mansion will be divided in the future, and the Xuanting Marquis Mansion will be divided at least half.

"Now I understand." Jiang Rong whispered.

"Oh...... It turns out that there is still this thing in this. ”

Bai Liyan was thinking in her heart that the father and son of Xuan Tinghou had lost money in their lives, and they knew that it was a fire pit, and they pushed their daughter in.

After a little brewing in his heart, Bai Liyan returned to the main hall, and Lan Yuan held the red-faced Xuanting County Lord, his face did not know whether he was happy or worried, or the pain of making a difficult choice.

"General Wei, the little girl will be entrusted to General Wei from now on, and I hope that General Wei can return to the court as soon as possible in this southern expedition, and renew the relationship between husband and wife with the little girl."

"Wei Xian, thank your mother-in-law."

Bai Liyan changed her words and called her mother-in-law, only the county lord of Xuanting was still hot on his cheeks, squirming and shyly burying his head, blushing and at a loss.

Xuan Tinghou stepped forward at this time, although his face was not about to succeed, but between his eyes, Baili Yan saw the light emitted by gold and silver.

"Virtuous son-in-law, go to the south this time with confidence, Benhou and the princess will definitely remove the worries of the virtuous son-in-law."

"Father-in-law Xie."

Bailiyan bowed and bowed, but she thought again, if she has a case, it is your father and son who have no worries.

After that, Jiang Rong and Lan Yuan took the Xuanting County Lord to bathe and change clothes, and Bailiyan arranged for the Xuanting Marquis and his son to live in the east wing of the mansion, waiting for him to leave. Qiao Cheng whispered:

"Father, did you say that my brother-in-law can come back alive from this southern expedition?"

"For my father, it is more auspicious than lucky, but I heard that the goods other than grain and grass in the south are very expensive, and now this war, it must be even more unreasonable, it is said that a pound of salt is sold for four or five hundred yuan, more than ten times the profit, but it is a pity that the goods of our Xianguo are not able to enter."

"Can't get in? Why can't I get in? ”

"Silly son, can other people's money-making territory allow our goods to enter."

"Father, there is still a shortage of materials in the world, and you are not allowed to sell goods?"

"It's not, if you don't sell the salt of the Hou Hou, sell it to the south at this time, it will be three times more profitable than selling it to Zhiguo, can the Hou not sell it."

"With such a big profit, wouldn't it be over if you let your brother-in-law build a piece of land?"

"Stupid!" Xuanting Hou scoffed: "Is it so easy for the Southern Barbarians to say that they will fight?" Your brother-in-law only has 30,000 horses, how can a copper-headed iron arm be an opponent of 800,000 Nanban. ”

"800,000, there are really a lot of Dingkou in this Nanban, if you can do the business on the territory of Nanban, it will be a great business."

"Just you are shrewd, why have you been in the Central Plains for so many years, isn't it just to rob our land, our silk silk, our rice and sugar. If this business can be done, it will be able to fight a war. ”

"Also to Ha ......"

At this time, Qiao Lian's words changed:

"By the way, what did your mother think about when you told your niece and granddaughter to the Luhou family last time?"

"It's just her, don't be a child. The child should be a beauty like his brother-in-law and sister-in-law, proficient in piano, chess, calligraphy and painting, and look good like his sister......"

"What's the use of being good-looking and not having a family background."

"My brother-in-law doesn't have a family background." Qiao Cheng retorted.

"That's your brother-in-law's genius, how can a woman be like your mother."

Xuan Tinghou blurted out a bad word, and was immediately grabbed by his son:

"Haha, the father said bad things behind his mother's back, and the child went to tell his mother!"

"Hey, you little bunny, betraying your father!"

"Unless the father agrees to marry the child, the child will not tell the mother."

"Okay, well, marry a beautiful woman......"

Qiao Lian agreed very quickly, and his psychology was 10,000 terrified of Princess Lan Yuan.

At this moment, Bailiyan was sitting in the bedroom, playing with the telescope in her hand, but she was thinking about why she hadn't come yet. At this moment, Jiang Rong pushed the door in Xuanting County, and Bai Liyan was also in good spirits, but she couldn't show her extraordinary excitement in front of Jiang Rong.

"Someone sent it to you, don't freak them out."

Jiang Rong said some kind of incision that could not be said and could only be understood, Baili Yan understood it in her heart, forcibly resisted her joy and impulsiveness, and made a serious face:

"Ahem, thank you Madame for mentioning it, you must be careful for your husband, you must be careful."

"Well, Sister Fu'er has to take care of it tonight, adults are not fuel-efficient lamps."

Qiao Fu'er blushed and nodded repeatedly:

"My sister thanked my sister."

When Jiang Rong was young, she withdrew from the dormitory, closed the door of the dormitory, and let the maid who accompanied her stay outside the door to wait.

Under the dim light, Bai Liyan reached out and touched the jade hand with skin like condensed fat, and in an instant, Qiao Fu'er's heart trembled, and she suddenly dodged half a step to the left.

"Fu'er."

"Adult ......"

"Are you afraid of me?"

"Well, a little bit ......" muttered a nod, and Qiao Fu'er sat down on the couch.

Bai Liyan sat on one side, wrapped her in her arms, undressed her with one hand, gently put her down, and stroked the delicate silky skin with both hands. When I was young, the lights in the house flickered, and it was faintly the indulgence and lingering love of men and women.

A few days later, King Xian was promoted to the general of Baili Yan's southern expedition, led an army of 30,000 to the south to conquer Qianyue Mountain, and paid homage to the general at the south gate the next day. King Xian patted Baili Yan on the shoulder and said earnestly:

"Wei Qing should be more careful when he goes, think about retreating when he encounters trouble, and put national affairs and family affairs first."

"Obey orders!"

"But is there anything else I need to explain to the widow?"

"Can the king take a step to speak?"

"Come with the widow."

When the two of them came to the outside of the crowd, Bai Liyan said carefully:

"The king, the minister will return to the south for a short time, and please be cautious about the affairs of the palace."

"What is Wei Qing referring to?"

"The prince, the princess and the prince's favorite concubine are infertility, and the king should deal with it properly as soon as possible, and when necessary, think about the other method and continue the incense."

"At this time, Wei Qing also knows?" King Xian asked rhetorically.

"The minister learned about this from the Marquis of Lu, and has been secretly investigating for a month, but has not found anything abnormal. But the minister can conclude that there must be secrets in it that we have not yet learned, and the king must beware of the other princes of the palace. ”

"Wei Qing wants to say that the Jin people have an unknown method that can make men and women cut off their heirs?"

"Yes, there must be such a law, but the minister has not yet found out. Therefore the king must be careful what he uses, wears, and eats. In addition, there is something that the minister does not know whether to talk about or not. ”

"But it doesn't hurt to say it, the widow is not guilty."

"The king should pay attention to the attitudes of individual families in the salt lords, and don't be understood by the villain."

"Who is Wei Qing referring to? Lu Hou? ”

"It's not." Bai Liyan denied: "Great King, the current situation in Xianguo is delicate, the prince is about to become an adult, according to the rule, there will be three or two years to assist the government." At that time, the salt lord family will begin to prepare for the prince's rule, and the relationship with the king will be estranged, if the matter of the prince's heirs cannot be resolved, even if the minister can protect the prince for forty years, after a hundred years, the hard work of the king and the minister may be in vain. ”

"Wei Qing is saying that there are people around the prince who have secret dealings with the Jin people."

"I'm afraid it's so ......"

Xianwang is forty and three this year, which is in the prime of life by modern standards, but the actual situation is much less satisfactory.

Nowadays, ordinary people live in their fifties without illness or disaster, and those who live to be in their sixties if the conditions are slightly better, and those who live to sixty and seventy are already dying. And the monarch can live past the age of fifty-five or sixty, and he can count it in thirty years.

King Xian is full of calculations and has no problem living for another eleven or twelve years, but he is basically dead for a long time, seventeen or eighteen years longer, and two or three years later, with the prince coming to the court and auxiliary government, the power relationship gradually shifted and changed. The salt lord family, which is attached to the Xian king, will turn to establish a new relationship with the crown prince, and if the prince still has only one child, and the other princes are sterilized, the political situation of the Xian kingdom will fall into an extremely difficult situation.
