Kaifeng, the imperial city of the Great Song Dynasty. In the vertical arch hall, Zhao Kuangyin summoned Fan Ruoshui. Of course, Zhao Kuangyin changed his name and is now called Fan Zhigu. The ministers who attended together were only King Jin, Yin Zhao Guangyi of Kaifeng Prefecture and Lu Duoxun, the governor of the Council.

"A few days ago, the minister sent someone to the quarry rock, and saw that the stone towers were all complete, and there were no traces of destruction. That Tang Jiang Guogong only depicted the bells and whistles on the cliff wall, and what the following ministers saw, it seemed to prevent others from carving words on the cliff wall again, so that a poem and a word of poetry would be unique on the stone wall. ”

"The Li family is a family of poets. The poem on this cliff is not enough, this word should be a first-class good word. Zhao Kuangyin snorted coldly. However, several people heard the sour meaning from it. Zhao Kuangyin boasted that he did not lose to any of the emperors of the previous dynasty, but compared the poems with the two or three demons of Li Yu's family, everyone responded to it in their hearts.

It was inconvenient for everyone to agree, and Zhao Kuangyin said to Fan Ruoshui: "In this way, you will go to Jingnan and supervise the construction of the bamboo raft." The required raft should be built within a few months. After that, he waited for orders in Jingnan. ”

"Obey." Fan Ruoshui's heart was excited, knowing that the matter of fighting Tang had been started. When the time comes, the pontoon bridge will be completed on the quarrying Yangtze River, and he will make a great contribution. At that time, the so-called self-reference is just Zhao Kuangyin's words of "horse bones in the golden city", so he will be put to rest; In this way, it can truly stand on the court of the Great Song Dynasty.

By July, it was already a scorching summer in Jiangnan.

Shi Taichu, the head of the Shi family in Wuyue Xiuzhou, ignored the hot weather and came to Xuancheng via Huzhou.

In June, the fishermen of Taihu Lake rebelled, affecting Xiuzhou, and then the Suzhou sailors entered Taihu Lake, and the remaining water villages of Taihu Lake were also quite disrespectful. Xiuzhou and Suzhou did not want to repeat the incident, so they expelled the Suzhou sailors from Taihu Lake. Let Li Congyi wait to see the good show of Wuyue Taihu Lake, and the idea of taking the opportunity to recruit some more Taihu Lake fishermen fell through.

When he first heard about the Taihu Kou rebellion, Shi Taichu was also shocked. Worried that Jiang Guogong would have an accident in Taihu Lake, triggering the Wu-Tang War. But when Shi Shi talked about the Taihu Lake process and no longer covered up Qian Hailu's matter, Shi Taichu was shocked and felt something keenly.

It's not that Wu and Tang will change because of a princess, but I think that Qian Hailu and Jiang Guogong's unbridled creativity in business are too similar. How old is Qian Hailu, and she is a woman, so come to think of it, many things are afraid that it is not the idea of this Jiang Guogong? If this is the case, even if this Tang State is annexed by the Song Dynasty, I am afraid that this Jiang Guogong will be able to stand still. With such a character, Shi Taichu naturally wanted to see him.

When Shi Tai first arrived in Xuancheng, he lived in the Jiangguo Mansion. Shi Junbi was originally a nephew of a distant house, but he excelled in his studies, Shi Taichu had only met him a few times, but he was not familiar with it, but because of his relationship with Jiang Guogong, he also brought it this time.

Jiang Guogong was busy with affairs, so he asked Wen Fangfei to receive him on his behalf. After Shi Taichu and the others settled down, they only rested in the room for their own identity. Shi Junbi walked around in the courtyard. But I saw a man under the shade of the tree, wearing a short shirt on his shirt, shorts on his lower body, a table and chairs, and he was writing hard.

There are people in the Jiangguo Mansion who are dressed like this, which is insulting. Shi Junbi said secretly, but he also had to admit that the other party's dress should look quite cool.

Shi Junbi walked behind the man, just to see what he was writing. At first glance, I was stunned.

It turned out that Chen Dong didn't want to learn those poems, so he just caused trouble in Jinling, and Chen Qiao was also afraid that he would be like Sun Yongning, so that his old man Sun Yanxiang would be "never at peace", so he sent Chen Dong to Li Congyi. Chen Qiao's move may have several meanings behind it, but there is no need to ask, and no one will say it.

When Chen Dong arrived in Xuanzhou, he was thrown into the barracks by Li Congyi for a month, but Chen Dong was the grandson of Wenchen after all, and after a month of hardship, Li Congyi transferred him back. Chen Dong likes military camp life very much, and only told Li Congyi that military camp life is really a subject that men must experience, and one month is a bit too short, which makes Li Congyi cry and laugh. Li Congyi didn't let him be idle, and asked him to teach in Guogongfu Primary School, Chen Dong was reluctant at first, but after he went, he became obsessed with this mathematics.

The current mathematics curriculum of Guogongfu Primary School is mainly that Li Congyi has made significant changes on the basis of nine chapters of arithmetic, introduced Arabic numerals, listed the ninety-nine multiplication table, and supplemented the calculation of area and volume. Of course, several teachers who were invited to teach mathematics in the later period also made more modifications on this basis to form the mathematics teaching book of Guogongfu Primary School from the first grade to the fifth grade. And Chen Dong spent a few days, almost hungry and thirsty to finish the five teaching books, and then looked for Li Congyi again. Li Congyi took some encounter problems, chase problems, flow problems, and economic problems, and asked Chen Dong to supplement them to enrich the content of the teaching book; He also told him some concepts such as multivariate multiple equations, surface area and volume of cylindrical conical circles, probability, linear algebra, etc., which Li Congyi also forgot, so he just wanted to talk about it and asked Chen Dong to help write middle school mathematics textbooks.

Chen Dong is now writing a middle school mathematics textbook. I was so engrossed in writing for a while, I didn't notice Shi Junbi; But Shi Junbi was shocked when he saw it. I can't imagine that any sloppy young man in the Jiangguo Mansion has such attainments. Chen Dong wrote a section, and he was a little stuck, so he was about to drink saliva, only to find Shi Junbi at this time, and he was startled.

Shi Junbi humbly asked for advice, and Chen Dong was also quite useful, so he chatted with Shi Junbi about this mathematics, saying that this is the key curriculum of Guogongfu Primary School, and anyone who cannot pass cannot graduate; It was also mentioned that the primary schools of Guogongfu used simplified Chinese characters for teaching Chinese, and the Arabic numerals were used for mathematics. Shi Junbi had never heard of these topics, so he followed Chen Dong to the Guogongfu Primary School next door to audit a few classes.

Shi Junbi said that he went to the yard to relax, but the person was gone. Shi Taichu waited for a while, then ignored him, and went out with Wen Fangfei, Xu Shiming and others to Xuanzhou Commerce and Trade and Xuanzhou Construction for inspection.

In the evening, when Li Congyi returned home, he asked Wen Fangfei, Xu Shiming, Xu Meilan and others to accompany Shi Taichu and Shi Junbi.

sent Shi Taichu back to the room, and several people discussed the matter together. Shi Taichu came over deliberately, and the main appeal was one: refined salt production method. If the chips given by Xiuzhou Shi are big enough, it is not impossible to give out the refined salt method, but what can Xiuzhou Shi come up with? This is precisely the reason why Shi Taichu came to Xuancheng in person, and he wanted Jiang Guogong to give Wen Fangfei's mother family some face.

On the morning of the second day, Li Congyi invited Shi Taichu to tea in the lounge, accompanied by Xu Shiming.

"The Shi family is certainly attached to the five major families in maritime trade, but there are also merchant ships that have been to the land of Japan. Although Japan is an island country, the island is quite large, and there are many people in the country, and many silk porcelain and other things are sold in Japan, often at ten times the price! "What Shi Taichu took out was the benefits of sea trade.

However, Qian Hailu is planning the Qiantang sea trade, and the Shi family is not strong in the sea trade, which is not very attractive.

Looking at Li Congyi's face, Shi Taichu understood that what he said just now could not fool people, so he could only show sincerity.

"The price of this refined salt is high, and it can only be sold to dignitaries at present; At the same time, it can only be sold to dignitaries and nobles in order to sell at a high price. This refined salt production really can't be as high as coarse salt, so as to maintain the price of refined salt at a high level. However, if the production of refined salt is too low, or if the initial price of coarse salt is too high, the total profit will be limited. Shi Taichu said, "The Shi family also has a salt field in Xiuzhou, but there is not much left after deducting the official salt; However, in Xiuzhou, private salt is at least 200,000 stone per year, and with the influence of my Shi family, it is not a problem to buy 50,000 stone. With 50,000 stone of private salt to make refined salt, the cost of coarse salt is extremely low, and the refined salt produced is not much, but it can be marketed in the Song, Tang and Wu Kingdoms. ”

"Shi is willing to cooperate with Xuanzhou Commerce and Trade to set up a company, specializing in this matter, Xuanzhou Commerce and Trade only need to use the refined salt method to buy shares, Shi Shi to pay money and people out of the venue, and the two sides each account for half of the shares. Sold in various shops and trades, the proceeds are equally divided. ”

Li Congyi also had to admit that he must not underestimate the wisdom of the world. Shi Taichu's idea is that Li Congyi will come out with technology, Shi Taichu will come out with manpower and get the raw materials, and the two will make a big one together, anyway, the market space is also large, and after the cost of raw materials is reduced and the output is increased, Li Congyi's absolute income will only be more and not less.

"This suggestion of the shopkeeper of Shida, it seems that my father has no reason to refuse." Li Congyi couldn't help but be authentic.

Zhou Zhihui made refined salt in the mountainous areas, so he could only boil salt, and he needed to cut down a lot of trees. And Xu Leshui's paper company is now beginning to enter the stage of large-scale production, and it also needs to cut down a large number of trees to make wood pulp. Therefore, Li Congyi rejected Xu Leshui's idea of taking out a loan from Jiangnan Bank and going to Xuancheng to build a second pulp and paper factory, and asked him to go to Jing County to build it, also thinking of dispersing it and putting less pressure on the environment. Anyway, there is also a Qingyi River in Jing County, and there is no big problem with waterwheel power.

When you arrive in Xiuzhou, you can dry salt.

After listening to Li Congyi's lecture on the method of drying salt, Shi Taichu was also shocked, this Jiang Guogong is omniscient. However, I think Jiang Guogong can actually make refined salt, and it is estimated that there is a lot of research on this salt drying method, so I must try this salt drying method when I go back. If it can be achieved, the cost of coarse salt can be reduced by a large margin, and the output can probably be increased, after all, under the boiling salt method, it is the seaside fuelwood that restricts the output of coarse salt.

At that time, the diffusion of technology was extremely slow, and Li Congyi was not worried that the salt drying method would quickly spread to Huainan, which would lead to a large increase in the production of sea salt in the Song Kingdom, thus making Zhao Song's finances more abundant.

Since the two sides agreed, Li Congyi called Zhou Zhihui over. Zhou Zhihui's two sons, Zhou Yuanying is now also the battalion commander, with more than 300 people under his hands, and Zhou Yuanqing is also the head of a division, and he is currently expanding his manpower.

Although he was reluctant in his heart, Zhou Zhihui also agreed happily, and was willing to lead more than a dozen villagers who had mastered the key links to move their families to Xiuzhou. For the time being, the village of Menkeng will be in charge of continuing production by his brothers, and it may also be relocated to Wuthering Heights in the future.

Shi Taichu and Zhou Zhihui also met and discussed many details, Shi Taichu wanted to return to Xiuzhou to prepare, and considered rehousing the menkeng people. Unexpectedly, Shi Junbi said that he wanted to stay in Xuancheng for a while longer, and what probability problem he wanted to study. Shi Taichu couldn't understand it for a while, so he didn't care about him and went back to Xiuzhou first.
