"Back to His Royal Highness, Caomin's father used to be a craftsman in a shipyard, and Caomin followed his father when he was a child, and at that time he was determined to be a shipbuilder and a shipbuilder. Yun Shou respectfully returned to the Dao.

"A boat?" Li Su wondered.

Du Zhiping explained: "Your Highness, in fact, it is the kind of ship model you brought, and it is also because of the model of this ship, I asked him to try it, but I didn't expect him to really have some ability." ”

"Let me see!" Li Su is interested, and there is really no shortage of talents among the people, and they can even make models.

Du Zhiping called a boatman and said a few words to him, and the boatman ran back to the shipyard, and after a while came out with a few small ship models, obviously this is the model made by Yun Shou himself.

"It's not easy!" Li Su took the model in his hand and played with a little surprised, Yun Shou made the ship model is also a kind of large ship, some similar to the Tang Dynasty building ship, although not as exquisite as the modern ship model, but it is also a look, out of the sail, what surprised Li Su is that on both sides of the ship is actually a paddle wheel, this new type of wood pulp is recorded in the Tang Dynasty Tianbao period was only revealed, this is what makes Li Su feel incredible.

Li Su opened his mouth to praise, and Yun Shou also showed a smile on his face, it was precisely because he was unwilling to accept his fate that he took the risk of taking his ship model to find Du Zhiping, hoping to join the shipyard to realize his dream since childhood.

"What is this thing for?" Li Su pointed to the bright wheel and deliberately pretended not to know and asked.

Yun Shou was a little embarrassed and said: "Your Highness, this is something that the grass people think wildly, because I saw the people in the village treading water with this kind of thing, so I thought that if I put this kind of thing on the boat, then I can paddle the water, and then I can let the boat go just like the wood pulp." ”

Li Su nodded, it all shows that it comes from life, this Yunshou is really smart, this bright wheel is not the same as the water wheel that takes water.

"Zhiping. Let's take him into Taoyuan to learn shipbuilding skills! Such talents are hard to come by, and Li Su plans to focus on cultivating.

Du Zhiping is an expert in steam engines, but not an expert in shipbuilding, although there are many craftsmen in the shipyard, but there are really not many outstanding craftsmen, after taking over the production of treasure ships, he is a first two big, fortunately with the help of Yunshou. Otherwise, he really didn't have the confidence to finish on time, although he learned some shipbuilding knowledge in Taoyuan, but he always felt that the steam engine was much simpler than shipbuilding, this time Li Su let Yun Shou enter Taoyuan to learn shipbuilding technology, he could finally be freed.

"Yes, Your Highness!" Du Zhiping said excitedly.

Li Hui has never said a word since he came down. Li Su looked at him as if Grandma Liu had entered the Grand View Garden, and was frightened stupid by the behemoths built by these five ships.

Although he was surprised that Yun Shou knew the paddle wheel, Li Su did not plan to use this old drive technology, since he had an advanced steam engine, he simply used the propeller as a driving device, and the treasure ship was also very suitable for large ships to be equipped with propellers, but he did not plan to give up the paddle steamer. He doesn't use it, but he can produce it and sell it to other merchants.

After inspecting the shipyard, Li Su took Li Hui back to Yizhou City, Li Hui was silent all the way, and he said to Li Su halfway: "Liulang, I will report to the college today." ”

In the past two days, all kinds of things in Yizhou have stimulated him too much, and he deeply feels that he is a frog at the bottom of the well, and at first he was dissatisfied with Li Xiaogong sending him to Yizhou. But now he finally understands his father's vision, and Li Xiaogong has many old friends in Yizhou, and it is these old friends who told Li Xiaogong about the changes in Yizhou when he visited him in Chang'an.

Li Su squinted at him, this is not Li Hui's character, if it was before, he would definitely have had enough of those fireworks before he went to do something serious, he really surprised Li Su by saying this.

"You're taking the wrong medicine!" Li Su stared at Li Hui and said.

Li Hui said: "Liulang can turn back as a prodigal son, and so can I!" ”

Li Su was speechless for a moment.

Li Hui and Li Su said goodbye and went directly to the Military Academy. Li Su showed a smug smile on his face, these places were deliberately taken by Li Xu, although Li Hui was smug, he was a very strong person. Li Su deliberately stimulated him, since Li Hui was his own retainer, Li Su didn't want a second ancestor to stay by his side to make trouble for him all day long, even if he agreed, those people under him probably wouldn't agree, it was difficult to accommodate him, Chengdu Palace didn't need people who were idle in mobile games.

Back at the palace, Li Su sent someone to call Tong Nian over, and I don't know how he negotiated with those wealthy families about the matter of this well salt.

Tong Nian was still tired on his face, obviously he didn't sleep well last night.

"How? Did they say yes? Li Su asked.

Tong Nian handed over a stack of contracts to Li Su, and said: "At first, they were still a little hesitant, they all wanted to sell by themselves, it was nothing more than thinking about speculation, but how could they be able to beat the Shengtang Chamber of Commerce, after all, the salt well is in our hands, and selling the well salt directly to the Shengtang Chamber of Commerce also saves them from finding their own sales channels."

Li Su nodded, he played the salt well card, these salt wells basically do not cost anything to Li Su, but for them it definitely takes a lot of time and money to play, and now Li Su sells the ready-made salt wells to them at almost half the price, which is equivalent to reducing the time for them to return their funds, and they can also see the benefits immediately, why don't they do it.

And Li Su is now equivalent to opening a business, but the business provides land, and he provides salt wells, these wealthy families are equivalent to the construction team, Li Su is completely empty gloves white wolf business, the hardest and most tiring work is done by the wealthy people, labor, transportation, and workshops are all their own way, Li Su only buys and sells, earns the largest profit in the middle, it is simply a million profits, as for sales and transportation, does the Tang Chamber of Commerce need to worry? This steamer is not an ornament.

Tong Nian had to admire Li Su, if the Shengtang Chamber of Commerce mined the salt wells alone, it would take a lot of costs to come to this labor, transportation, and construction itself, and now these costs have all been saved.

After the participation of the Hao family, the output of this well salt must increase by multiples, if Li Su's mining capacity is one, then the overall mining capacity is now one hundred, as a total sales, Li Su earns more money than his own mining, and at the same time saves a lot of management costs, and can make the Hao people only prosperous Tang Chamber of Commerce Ma is Zhan.

Of course, these wealthy families are not stupid, no matter how hard and tired the construction team is, it is also profitable, although the profit is not as good as the business, but it is enough to make a bulging pocket.

Li Su also considered that in order to be able to regulate the price of salt, like the specialty store, the Shengtang Chamber of Commerce set the retail price of goods to avoid merchants from raising or lowering prices at will, causing malicious competition.

After looking at the contracts for a while, these contracts are the requirements of both parties for their respective rights and obligations, but in fact, they are just Li Su's overlord clauses: "You and Shangguanyi discuss that these salt wells will be included in the management of the salt well supervisor, and you must accurately grasp the salt production of each salt well, put an end to smuggling, and handle and recover their salt wells according to law for those wealthy families who smuggle salt from the wells." ”

Tong Nian nodded emphatically, this salt industry is not a joke, for this reason, the Shengtang Chamber of Commerce has also set up a special salt industry department responsible for the purchase and sales of well salt.

and discussed some details with Tong Nian, Tong Nian got up and went to Shangguanyi, although these things are operated by the Tang Chamber of Commerce, but after all, they are in the name of official salt, and some things have to be cooperated with by Shangguanyi.

After several discussions, the well salt industry finally came up with a general policy, and the vigorous salt industry movement officially began in Chengdu Prefecture, and some businessmen with capital began to buy salt wells from the Tang Chamber of Commerce, and workshops were erected around the salt wells.

After inspecting the demand for well salt, the Shengtang Chamber of Commerce is ready to sell 1,000 salt wells, and then continue to develop according to market demand, after all, the Shengtang Chamber of Commerce bears the risk of sales, and the sale of this thousand salt wells has made Li Su make a lot of money.

At the same time, the sweet potato exhibition also officially began in Yizhou, and businessmen from all over the Tang Dynasty tasted this new delicacy for the first time.

As for the peanuts Li Su did not sell directly, but built an oil extraction workshop, ready to use these peanuts to produce vegetable oil, once this batch of vegetable oil is produced, Yizhou's catering industry will have revolutionary changes, now, Li Su is more and more keen to popularize all kinds of new things in Yizhou, which makes him have a sense of pleasure in playing a strategic game, watching Yizhou in his own hands little by little changes, this mood is really indescribable.

And when Li Su was complacent about his achievements, the eyes of the entire Tang Dynasty were once again focused on Chengdu Mansion, but this time it was not for the potatoes in Yizhou, nor for the sweet potatoes in Yizhou, but in Songzhou, another place in Chengdu Mansion.

In October of the eighth year of Zhenguan, Tuyuhun attacked Songzhou, at this time in history, Tuyuhun attacked Shanzhou in Qinghai region, since Li Yuanwude's Tuyuhun raided the Tang Dynasty has not stopped, the peace between the two sides has never been more than half a year, and Li Shimin succeeded to the throne, although this attack has decreased, but it is still continuing.

"Tuyuhun chose to attack Songzhou because His Royal Highness had just taken over Chengdu Mansion, and the foundation was unstable, and there were few soldiers and generals in Chengdu Mansion, and they were still very rich. Zhu Youzhi said with a deep groan.

"Don't talk about this yet, this Tuyuhun is too shameless, His Majesty agreed to marry the princess to his son, it was his son who pretended to be sick and didn't want His Majesty Xià to cancel the marriage, they now say that we don't talk about it, such a scoundrel doesn't teach him how to do it." Qin Huaiyu shouted.

As soon as his words fell, a scout on horseback stopped in front of the palace gate and hurriedly entered the main hall, "Your Highness, Tuyuhun is known as an army of 80,000 and has set up camp outside Songzhou City. ”
