Lin Lingsu's eyes lit up, and he hurriedly asked, "What is that, so important?" ”

"That's an element called iodine. Iodine is added to an appropriate amount of alcohol to produce iodophor, which can prevent wound infection. ”

Zong Shu felt that he couldn't explain it anymore, and if he continued to explain it, it would be bacteria or something, and now he couldn't let Lin Lingsu see it.

"Master, how to extract this, iodine?"

Lin Lingsu usually takes a group of disciples to roast all kinds of substances, and he has also obtained some new substances, such as mercury and the like. I feel that it should not be difficult to extract this element that Zong Shu said.

Zong Shu said honestly: "This is quite difficult, the extraction process is very cumbersome, the equipment used is very exquisite, and every link needs to be very precise. ”

First of all, the dried kelp is roasted in an iron dish to make the kelp completely ashed.

After that, the kelp ashes are poured into a beaker, distilled water is added to boil in turn, and after each boiling, the upper layer is poured out of the upper layer for the night and filtered.

The filtrate and the tertiary leaching solution were combined and an acidic solution was added to the filtrate. Place the flask with water-cooled on the beaker spout.

The resulting iodine sublimates by heating the beaker, and the iodine vapor condenses at the bottom of the flask, becomes crystals, and is retracted.

It's easy to say, but it's hard to do, adding distilled water, acidic solutions, etc., not a drop more, not a little less.

Lin Lingsu asked what a beaker was and what was an acidic solution.

Zong Shu explained again, why is it so difficult. Now I can't make PH test strips or anything like that.

In these years, if you want to engage in science and technology, there are too many aspects involved, and you can't do it if you can't meet any of the conditions.

Zong Shu wanted to make an airplane cannon, but is it possible? Without a complete industrial system and strong scientific research support, it is simply impossible.

Lin Lingsu said with a solemn face, "Master, can you let me give it a try?"

Zong Shu, as a science and engineering man, came to the Song Dynasty to actually want to make a career, for example, the extraction of iodine, if proposed, it would be a big boost to the development of medicine and chemistry in the Great Song Dynasty.

But judging from the current conditions, Zong Shu can't extract it for the time being.

Lin Lingsu actually took the initiative to ask Ying to do this! Zong Shu was about to fall asleep, and Lin Lingsu sent a pillow.

Lin Lingsu has a certain amount of experience in alchemy, and his Taoist disciples will also do it, if they suggest a direction, they may really be able to come up with something good.

Lin Lingsu led his children around to swagger and deceive, which was also forced by life. They have also done some good deeds, such as Lin Lingsu finding the charcoal in Yingtianfu.

As long as they are well guided, these magic sticks can be completely transformed into talents with a scientific spirit.

"In the future, extract the elements, and let your disciples do it, this is called technology, this is art. You follow me, mainly to learn the truth, the scientific truth, this is the Tao. This is Taoism. Without the Tao, the art is not right. Without art, there is no way to prove. Zong Shu said.

Lin Lingsu was greatly impressed when he heard it. In the future, if anyone said that the master was illiterate, he would be the first to refuse.

Thinking of iodophor, Zong Shu immediately thought of Zong Ze. According to historical records, Zong Ze died of a poisonous sore.

The reason why the poisonous sores are becoming more and more poisonous is because the pus is not clean, and the hole is broken, and it is infected inside and out. If iodophor is present, the chance of infection is greatly reduced.

For the sake of Zong Ze, a famous anti-gold general, the iodine element has to be extracted, and the progress has to be accelerated.

There must be a brave man under the heavy reward, Zong Shu took out two silver tickets, a total of 200 taels, and handed them to Lin Lingsu.

Lin Lingsu panicked, how can this be done, it is right to do things for the master, how can he ask for silver?

Zong Shu's face was stunned, your disciple studied this all day long, don't you need to eat? Why do you really want to be an immortal?

"With iodine extracted, there will be other new elements extracted, and there is much more to be done. You don't want money, but what about your disciples? It is only natural to work and get money. Zong Shu said.

Lin Lingsu's Taoist temple is called Tongzhen Palace, which is twenty miles outside the city. Lin Lingsu was going to hand over the matter of extracting the elements to his disciples, and he would complete it in the Tongzhen Palace.

Usually he followed Zong Shu to learn the Tao, and as for the arts, he let his disciples do it.

Zong Shu is very satisfied, this Lin Lingsu is really, very good.

Lin Lingsu asked Master Kong for a bunch of kelp, led a donkey, and went out of the city.

As soon as Lin Lingsu left, Zong Ze and Zong Yi came back with people.

Looking at Zong Ze and Zong Yi's red faces, you know that the gambling house in the capital has closed down again: the Wang family gambling house.

What Zong Shu is most concerned about is how much silver he got back from the Wang Family Gambling House. In the future, when there are more places where the silver is used, the expenses will become larger and larger.

In particular, the mining of coal in Mixian County must have invested a lot in the early stage.

Zong Shu asked Zongyi, who knew that Zongyi couldn't take care of him, but instructed everyone to put away all kinds of calligraphy, paintings, porcelain and other antiques that he pulled back.

There are still people outside the courtyard who carry things inside, it seems that the Wang family gambling house is really bankrupt, the money is gone, and the things are used as collateral.

Zong Shen came over and told Zong Shu that this time the Wang family gambling house gave 700,000 taels of silver. The rest can't afford to pay off, so everyone emptied Wang Youcai's house.

So arrogant? Just get all the money. Zongyi emptied Wang Youcai's house, isn't this equivalent to raiding the house?

It's not Daddy's style! He's always been submissive, how could he?

Could it be that he was too arrogant and deviated from his father's rhythm?

Zong Shen hurriedly said to Zong Shu that when he arrived at the Wang's gambling house, Cai Xiu happened to be there. Seeing that Zong Ze was coming, Cai Xiu was so frightened that he hid.

All the silver tickets and cash of the royal gambling house were taken. That's not all, all the things in the shop and Wang Youcai's house have been moved.

It turned out that it was not the daddy maniac, but the Zongze maniac. Zong Ze really dared to be scared by anyone back then, he died at the age of 68, and he died of illness.

As for Yue Fei, foolish loyalty, to put it bluntly, he was too honest, and finally died tragically by Qin Hui on the "trumped-up" charge.

People are crazy and live long. People are low-key and dead. That's it!

Zong Shu saw that Zongyi was busy before and after, he was quite distressed, and pulled Zongyi and said:

"Dad, how to place things, you can leave it to others. You have to learn to enjoy life! ”

Zong Shu took Zong Yi and Zong Ze to the backyard and asked Master Kong to serve a dish first.

Zong Ze and Zong Yi tasted it, isn't there anything special?

Zong Shu dipped a little white crystal from the porcelain bowl on the table with chopsticks and stirred it in the dish, "Now, how about tasting it again." ”

Didn't you just put salt in it? If you put more salt, wouldn't it be even more salty, can you still eat it?

As soon as they entered, Zong Yi and Zong Ze's eyes widened. What does it smell like? So, special?

"Uncle, Daddy, this is MSG, Master Kong, it's extracted!" Zong Shu became excited, and Master Kong was also rubbing his hands excitedly.

It's true? Zongyi immediately stood up and approached the porcelain bowl to look. It looks like salt, but it definitely doesn't taste like salt.

Zong Ze doesn't know why, isn't it just a seasoning, as for being so excited?

Of course, Zongyi is aware of the business opportunities here, and it seems that it is time to set up a shop specializing in selling MSG.

"Shu'er, we have set up a new shop, what is the price of this?" Zong Shu asked.

"In this porcelain bowl at present, such a little bit will sell for at least one or two pieces of silver!" Zong Shu said.

For a little bit, sell for a tael of silver, which is more expensive than salt. Salt is a government monopoly, and no one else is allowed to touch it. So, salt is more expensive.

And the price set by Zong Shu is too high, right?

Zong Shu said: "MSG, we are a monopoly, of course we have to pay a high price!" Moreover, the MSG market is currently for high-ranking officials and the wealthy, and the price is low, how does it reflect the identity and value? ”

Zong Ze couldn't help sighing, it's just that his younger brother is a businessman, this nephew is more profiteer than a profiteer, how can such a person become a protégé of the Son of Heaven?

The protégé of the Son of Heaven has become a fact, so he should take the opportunity to give more advice to the officials.

"Shu'er, since you are a protégé of the Son of Heaven, you will do something to repay the king. Now that the villains in the court are in charge, they are filthy, you not only have to clean yourself, but you also need to speak up and do a good job. ”

Zong Ze instructed.

Zong Shu promised on his lips, but he was thinking in his heart, what is the point of Qingyi and Qingliu?

Just by moving his mouth, he can kill the villain and drive the golden man away?

Lao Tzu, just speak with strength, don't be a clear stream, and swear to be a big Song mudslide!

What about Cai Jing, Tong Guan, Liang Shicheng, and Li Yan? No one can stop it!
