With iodine, wounded on the battlefield, timely disinfection, will significantly reduce the mortality rate of fighters.

In modern society, medical conditions are complete, and wounds in general areas are fine.

However, in ancient times, the medical system was not perfect, and it was okay to treat chronic diseases and recuperate physically and mentally, but there were not many ways to deal with external injuries, and the effect was not good. The possibility of death from trauma is very high.

In the Song Dynasty, there was the Tai Hospital in the center, which was dedicated to serving the royal family and high-ranking officials of the imperial court.

It was not until after the Jingkang Revolution that medical hospitals were set up in various places, which were military hospitals in the true sense.

Along with the movement of the army, there are also military doctors.

At this time, the military doctors were basically all veterinarians.

Because in the Northern Song Dynasty, the lives of sergeants were sometimes really inferior to horses.

After the loss of important horse-producing areas such as Yanyun Sixteen Prefectures, it became extremely difficult for the cavalry of the Song Dynasty to supply horses, and the Song Dynasty even opened up horse markets and other special markets to supply the cavalry.

The horses themselves cost a lot of money, and the outbreak of horse disease caused a large number of deaths in horses, so the Song Dynasty established a special institution in charge of veterinarians.

In the event of war, the military doctors would also go with the team, and their main task was to treat the wounded horses and save the sergeants by the way.

It can also be said that if a sergeant does not receive good medical care on the battlefield, he will naturally not fight hard or fight to the death.

This is also an important reason why the other Great Song armies are weak except for the "Seed Army".

At the beginning, I had the idea of escaping and retreating and letting others take over, how could I win?

Therefore, in order to enhance the combat effectiveness of the armed forces, propaganda and mobilization are of course very important, but they must be guaranteed by sufficient material conditions.

Now, Zong Shu only has twenty-nine sergeants in his hands, including Niu Gao.

This amount of strength is equivalent to two squads, not even a platoon. But on some special occasions, more troops is not always better.

There are not many soldiers, but refinement.

Zong Shu had high hopes for Niu Gao and the other 28 sergeants, which was his capital to save his life, his family, and even the country in the future.

To solve their medical problems, it is not possible to bring military doctors, and it is difficult to find specialized military doctors, and even if they do, they will affect the overall operation because of their low military quality.

Therefore, the best thing to do is to equip each sergeant with a battlefield first aid kit.

Put bandages, cotton balls, iodophor and penicillin in the first aid kit. With these, the warrior was wounded, at least not afraid of infection.

Therefore, it is most important to get iodophor and penicillin out now.

Lin Lingsu brought a few Taoist priests, and Zong Shu let them live in the courtyard of the Zong family to analyze, study and experiment together.

In order to increase the speed, Zong Shu specially pumped Master Kong over and asked him to be responsible for the extraction of alcohol.

Zong Shu specially told Steward Qiao that no one was allowed to approach near the small building in his study, including Daddy Zongyi.

Master Kong has quite experience in extracting MSG from kelp, but this time the pure alcohol extracted from rice wine is different.

Zong Shu asked Master Kong's people to build a distillation pot outside the study, and used the method of boiling wine at low temperatures, evaporating the alcohol from the water, and then guiding it to another glassware to cool it with a porcelain tube.

Because alcohol volatilizes from a liquid into a gas, it takes fifty to sixty degrees.

It's just that there is no thermometer yet, so it can't be measured accurately. Therefore, the temperature can only be measured by feeling.

Fortunately, the rice wine of this era is not expensive, and there is nothing to waste at all.

As for the production of thermometers, this is again a special project, which requires the establishment of a special research team.

If you want to engage in science and technology, you must have a complete and rigorous system, and now, you are basically starting from scratch.

Finally, there was half the alcohol in the glass, and the purity was quite good.

In the process of Zong Shu instructing Master Kong to purify alcohol, Lin Lingsu also took several Taoist priests to observe and learn on the spot.

Unexpectedly, Zong Shu made half a glass of water through the method of steaming, guiding, and cooling, of course, this glass of water is the alcohol that Zong Shu has been talking about.

Zong Shu handed the cup to everyone and let everyone smell it.

As soon as you smell it, everyone feels a strong pungent taste, which is the taste of sake. However, it is much more choking than ordinary rice wine.

Master Kong took another sip and immediately felt a fire in his throat.

Immediately, regardless of his age, Master Kong jumped up like a child: "Young Master, you are too powerful, this is another way to make money!" ”

Lin Lingsu tasted it again, and felt that the name given by Zong Shu was too appropriate, alcohol, isn't it the essence of wine?

This wine was the thickest and purest he had ever tasted.

After drinking alcohol, I will drink rice wine or something in the future, and I will not taste at all.

"Young master, we can make this kind of wine and sell it soon!"

Master Kong knew that since the young master asked him to purify the alcohol, he would definitely hand over this money-making business to him to be in charge.

"From now on, you will be in charge of making and selling wine. In the past few days, it will be purified first and handed over to the spirit element. He has a greater use. ”

The oranges in Zong Shu's study are rotting, but the degree of mildew is not enough, and they need to wait a little longer.

With alcohol, coupled with the iodine element that Lin Lingsu has extracted, iodophor can come out.

As long as there are raw materials, the preparation is simple, no more than one percent of iodine is mixed with 99% alcohol, and it is done.

After a while, Lin Lingsu prepared the dark brown iodine, that's it!

"Master, according to what you said, alcohol and iodophor can be disinfected, so why not just use alcohol?" Lin Lingsu asked a question.

This is the rigorous attitude that scientific and technological workers should have, Zong Shu glanced at Lin Lingsu with satisfaction and said:

"Alcohol is characterized by being volatile and unbearable when in contact with wounds. The irritation and pain caused by iodophor are mild, and it is relatively non-volatile, low toxicity and non-corrosive. ”

Zong Shu also confessed to Lin Lingsu that the formula of iodophor was kept strictly secret, and the business of iodophor was also handed over to the Great Song Academy of Sciences.

In this way, we can ensure the integration of production, learning, research and marketing, and promote the faster transformation of science and technology into economic benefits.

And good economic benefits will promote the faster development of science and technology.

In this way, Da Song's science and technology can embark on the track of a virtuous circle.

Zong Shu called Lin Lingsu to the study and asked him to observe the mildew of oranges with the Taoist priests.

Now there are only a few mildew spots on oranges, and when the mildew expands and darkens, and the color turns cyan, you can use a knife to carefully scrape off the cyan mold ash and collect it.

These cyan mold ashes are Penicillium and need to be placed in a laboratory vessel as a culture medium.

At the current study temperature, distilled water can be added to stir to become Penicillium fermentation broth.

Penicillium fermentation broth is heated and cooled, filtered and added with an acidic extract extracted from plant ash, and finally added as a salt agent, which is penicillin after azeotropic distillation.

The process was very complicated, and Lin Lingsu's apprentices also used sharpened charcoal pens to write them down word for word.

If penicillin is made, then other drugs, Lin Lingsu will also follow the cat's example.

Of course, the most important thing is to let Lin Lingsu know the principle through this process.

After explaining this matter, Zong Shu, accompanied by Li Shaoyan, traveled almost all over Bianliang City, going in and out of scissors shops, cloth shops, tailor shops, blacksmith shops and other shops, busy.

In order to save time, Zong Shu and Li Shaoyan both rode small donkeys. These days, it can really be described as a donkey's non-stop.

It's a pity that there are no horses now!

Without a horse, he can't even catch a little thief, how can he save the breeder Dao and Wu Jue?

Zong Shu couldn't help but have a headache.
