Seeing the concentrated salt water filtered through layers of cotton cloth, the smart Wu Yuan had already thought of the trick: "Sir, is this method of salt making the same as your method of filtering water?" ”

"Pretty much." Jiang Tian did not pause in his hand, because there was no suitable filter paper, he could only filter it many times: "It's just that the purifier is to remove the impurities in the water, and the salt production is to remove other impurities other than salt." ”

The filtered concentrated brine was packed into a fine porcelain plate, and then Jiang Tian put the plate in the sun and exposed it: "Although it is early autumn, the sun is very strong, and after a while, the water evaporates and only refined salt remains." ”

Huan'er, who had been staying on the side and was silent, finally couldn't help it at this time: "It turns out that this coarse salt becomes refined salt so easily!" So why is there still a shortage of salt in Beijing? ”

Jiang Tian thought to himself, why did this children's version of 100,000 speak again, how can a rich child like you understand the suffering of the people in the market: "It's not that there is a shortage of salt in Beijing, but that the refined salt has been bought. I heard that after the Holy Lord controlled a few salt farms, he made a large number of refined salt to sell in the market, and you also know that there is not much advanced knowledge here, so the price of salt has always been inflated, and the cheap refined salt has hit the stability of the salt market, and lowered the price, which makes it possible for the people now to buy some refined salt for retention. However, most people still don't know the doorway, and the method of preparing refined salt is also a secret method that the imperial court keeps secret, which ensures that although the price of salt has been reduced, it has not affected too much profit. The salt merchants did not expect that just the Mongolian tribes who came to Beijing for the pilgrimage would be able to eat up the reserves on the market with a great appetite, so they were caught off guard, but fortunately, the capital is not far from the salt farm, and a large number of goods will replenish the market in a few days, and the salt shortage will naturally be solved! ”

In fact, Wu Yuan knew better than Jiang Tian that salt was already an important income of the imperial court, and those salt merchants in the south of the Yangtze River were knocked over by this kind of high-quality and low-cost salt at the beginning, and military salt completely replaced private salt, and became the best-selling goods in the north and south of the year. In recent years, due to the purchase of a large amount of overseas grain, the treasury was in urgent need of cash, so it was allowed to allow some Mongolian tribes to come to trade.

"Sir!" Recalling the controversy in the court, Wu Yuan decided to listen to Jiang Tian's opinion: "Most of the Mongols who come here for pilgrimage are small tribes, how can they buy so many things, I think it is nothing more than buying them back and selling them to other tribes, so that those who are hostile to China will be funded?" ”

Jiang Tian nodded: "That's a good question!" But you have to know that even if the country doesn't sell, there will be a large number of profiteers waiting to smuggle it. Rather than this, it is better to open up and let them buy, as long as the price is fair, they will not have the idea of robbery, and even if some tribes who are used to robbing look at it, the army on the border is not as bullied as Qianming. In the long run, as long as this kind of trade can be done for a long time, then the products of the Central Plains will be flooded with grasslands, and those who are accustomed to the tools of the Central Plains and enjoy the milk tea mixed with salt will want to return to the previous days of lack of food and clothing? When they run out of money, they will exchange livestock, horses, and even population, and in the long run, the stronger the stronger, the weaker the weaker. Remember what I said the other day about the tube? Doing business is sometimes more efficient than robbery. ”

The real yàn of salt making is very simple, but Jiang Tian spent a long time with these two brothers to explain what is the scissors difference, the scale effect of the Central Plains makes the cost of the product very low, and selling it to areas with low productivity can earn extremely high added value, the bloody process of this civilized looting method is no less than cutting people with a saber, as long as we can ensure a certain military force so that the other party can not turn the other side, and at the same time ensure that the production cost is always lower than the other party, then this trade surplus will always exist.

As he spoke, the salt water under the scorching sun also crystallized into fine salt grains, Jiang Tian picked some dry salt and put it in his palm, and then rubbed it vigorously: "You see, this is not much better than the best refined salt, right?" ”

Wu Yuan pinched a handful and looked at it carefully for a long time, he had to admit that the method of preparing refined salt, which even he couldn't know, was actually that simple. No wonder the Holy One was able to keep his army running with salt. But he was surprised to find that many of the things that Jiang Tian explained to him were similar to what the Holy Lord said to him in private, including various words that had never been used before. In fact, Jiang Tian's identity not only attracted the attention of the three high-ranking officials and dignitaries, but many people were secretly observing this guy who suddenly appeared, but the methods they used were a little different, and there were very few people like the fake prince who humbly sought advice after all, because others did not have such a big backer as the emperor.

Boss Zhao is ostensibly taking care of the business, in fact, he has been listening carefully to Jiang Tian's explanation of how to prepare refined salt, and seeing that now he is a person who has nothing to do with science and understands, so this stingy old man's mind has moved again, and he has made up his mind to only buy coarse salt in the future, and he can save one or two silver a year. Zhao Zhi was also dumbfounded, he always thought that his master was just able to tell stories, but he didn't expect that casually saying a way was a big deal of daily money, but it was a pity that he had to get permission from the court to sell salt, otherwise he could make a fortune as long as he worked diligently for a few years.

At this time, there was an intermittent sound of silk and bamboo in the red building opposite the door, Jiang Tian didn't need to listen carefully to know that they were rehearsing their new songs, but they hadn't mastered the essentials and seemed very jerky, Wu Yuan also listened to it for a while, don't look at the score was recorded by him, but he was already surprised by the unskilled performance. It turned out that he was also born in Jiangnan, and he was still very familiar with the tunes there, and the small songs he was used to hearing were only slightly modified by Jiang Tian and had been reborn. Although it is not known what the others have prepared, there is a great hope that this piece will win the Oiran. Thinking of this, he stood up and bowed his hand towards Jiang Tian.

"Sir's teaching today has benefited the students a lot, although I don't know why Mr. is not an official, but the imperial court does need a pillar of talent like you, and I hope Mr. will think about it more......"

Looking at the distant backs of the two brothers, Jiang Tian still couldn't figure out what they wanted to do? If Wu Yuan is really the kind of young talent who is thirsty for knowledge, and the various behaviors he shows show that he really likes science, then what is the purpose of his repeated tricks? Thinking of this person's life experience, I am afraid that the purpose of the pervert is the same, that is, someone is eyeing him. In this way, things will be easy to do, Jiang Tian pondered for a while, and then beckoned Zhao Zhi over.

"I'll ask you to do something......"

A few days have passed, and the matter of Jiang Tian's resignation has spread all over the city, and now many people are talking about the first strange person who appeared in this dynasty. Generally speaking, at the beginning of each dynasty, those founding emperors would show that they were eager to seek talent, and repeatedly invited several great Confucians with high folk prestige to come out of the mountain. As for whether the celebrities who were invited to the court can play their due role, this is a matter of opinion. Therefore, Jiang Tian was entrusted with an official position and was also regarded as the vane of the imperial court, after all, he still has a reputation for showing talent, and recently he has a small reputation in Beijing, and the most important thing is that kind of new talent who is good at the study of things. So people don't take Jiang Tian's resignation very seriously, thinking that Zhuge Liang still tossed Liu Bei three times, wouldn't it be underestimated if he didn't put on a good shelf? Besides, the new emperor opened a killing spree to Donglin, and you, the saint's disciple, also have to express it, and then the emperor should sigh that his previous killing was too heavy, so that the virtuous people were unwilling to serve the king, admit their mistakes and make a gesture of reconciliation, and the scholars in the world should do whatever they want. Jiang Tian continued to be an official and the others continued the scientific expedition, and returned to the normal track.

The problem is that although this routine is very good, Jiang Tian is not a player who plays cards according to the routine, just when the Confucian scholars in Beijing were keeping an eye on the follow-up development, before waiting for the new developments of the imperial court, they heard a lot of Jiang Tian scolding the words, and there are rumors that there is a nose and eyes to describe how a madman insulted Yasheng, and admired the pre-Qin pipe thought, so that even Confucius was said to be a deceitful and famous thief who painted a tiger and did not become an anti-dog! This really stabbed the hornet's nest, and the students who were waiting for Confucianism to turn over found out that Jiang Tian was a traitor, if such a person was specially recruited by the imperial court, wouldn't it ruin the foundation of Confucianism for 2,000 years? Not to mention that Song Yingxing didn't dare to squeak, even Wu Yuan didn't dare to come to the door again, they were afraid that people would misunderstand, thinking that the imperial court was going to hire this kind of person to fight Confucianism. Besides, those literati couldn't let such an alien make a big splash, so all kinds of insults and attacks came like a tide, and those who were idle came to him to theorize.

"When you open your mouth and close your mouth, what the saints say, what the saints think, I want to ask you if you have any brains? Can you think of a cause and effect when you encounter something? Whoever prescribes the words of the saints must be correct? Is it smart or foolish for you to let someone from 2,000 years ago rule for you? Since you listen to the words of the sage so much, okay......" Jiang Tian picked up a five-dan bow and pointed out the door: "If any of you can use this bow to shoot a target fifty paces away, and can drive the carriage outside the door around the capital, I will treat you as a real Confucian, and then listen to your high opinions, if you can't do it, you will be a person who sells fame and reputation, and don't come out next time to be embarrassed." ”

There are many people who want to come to scold and fight every day, but Jiang Tian was blocked by Jiang Tian with such a lack of morality without saying a few words, and let these weak scholars open bows and shoot arrows, driving a carriage is definitely a technical job, and it is not good to play this kind of advanced transportation without a few years of driving experience, but among the six arts of the gentleman, driving and archery are among them, if you are not embarrassed to say that you are an authentic Confucian student? Of course, there are also active justifications who don't want to be fooled, saying that in the pre-Qin era, there was no distinction between civil and military, and the skills of control and archery were naturally important, but now there is a difference between civil and military, and scholars no longer need to study martial arts. Generally speaking, Jiang Tian would laugh out loud when he said this, and then asked the other party, since you also know that this time is different from the pre-Qin, there is no unchangeable rule, what is your intention to be so selectively blind?

In short, this is a two-end trap, real smart people such as Tian Xuhai will only walk around and will not step in, but there are so many unsightly people who take the initiative to send to Jiang Tian to brush his reputation, naturally he is also very cooperative with the daily driving trip to swagger through the city, this car is rented by Jiang Tian to Zhao Zhi, every day either to the suburbs or to the workshop to guide Song Yi, or to the opposite door to watch the song and dance, to do a typical wild and uninhibited talent image. If you are in a good mood in the evening, you will make a cameo appearance and perform one or two cross talks, and it seems that the small life is having a good time. But everyone guessed that this kid really didn't plan to be an official, otherwise he wouldn't have done things so desperately, you must know that the civil officials in the court are still mainly Confucian, and even if the emperor wants to use you like this, there will be a lot of officials who oppose it.

"Mr. Liu, the students have something to ask for." In the backyard, Jiang Tian respectfully toasted a cup of tea to the thin old man.

Old man Liu hurriedly took it with both hands, in terms of status, Jiang Tian was above him, don't care about what others ask him to do, at least the etiquette can't be bad: "Son, you're polite, I don't know what to ask for?" ”

Jiang Tian turned his head and shouted, "Come here." ”

Zhao Zhi trotted over to look at him, Jiang Tian nodded and said: "Mr. Liu, I accepted this child but didn't let him apprentice, that's because the student is only shallow in learning, and I can't let him eat this bowl of open rice, and I don't ask Mr. to accept him as an apprentice, as long as he can give him a pointer or two, he can have a skill, and this scholarship will not treat Mr. badly." ”

Old man Liu frowned and made it difficult, to say that even if he accepted a little apprentice, it was nothing, the key was that this kid had already learned a bunch of things from Jiang Tian, of course, Jiang Xiucai could tell the story no matter how he wanted, people just wanted to have fun, not people in this door, but this kid would definitely have to rely on storytelling to eat in the future. If he really accepts him and spreads it out in the future, I'm afraid that his peers will blame him for helping the aliens.

Jiang Tian saw him hesitate, and probably guessed what he was thinking, so he continued to say: "You don't have to worry too much, what you learn and how much you learn are up to you, and in this courtyard, you can not recognize this student when you go out, he will not go on stage to tell a story without your permission, even if it is what I taught him, your reputation will not be damaged." If you agree, the fifty taels of silver will be my thank you gift! ”

As soon as he made a move, it was fifty taels of silver, and the old man's eyes widened. I heard that this kid made a fortune, and when I saw it today, I knew that what he said was true, and now the best paddy fields in the countryside are only a few taels of silver per acre? Even in Beijing, it is enough for a family of three to eat for five or six years. After thinking about it, he was finally moved by the white silver, and the old man nodded slowly and agreed.
