The emergence of paper will provide a convenient carrier for the dissemination of knowledge, as long as the process of papermaking is gradually improved, the education of Xia Kingdom will have a blowout development.

The first kind of paper manufactured, although rough, but this paper naturally has its uses, this kind of straw paper is a very good choice to use as toilet paper, after all, as a modern Wang Lang, every time he uses wooden sticks and leaves to wipe his buttocks, he has long endured enough.

After ordering the Ministry of Industry to make a batch of this straw paper and deliver it to his residence, Wang Lang left here.

On Wang Lang's return from the Ministry of Industry, he saw a lot of people gathered in front of the Daxia Medical Hall, and out of curiosity, he followed the guards over.

When the people saw Wang Lang coming, they consciously got out of the way.

Walking into the infirmary, Wang Lang saw several wizards treating a wounded man who had been pierced in the arm by a wooden thorn.

Wang Lang didn't disturb the work of these wizards, just stood quietly aside.

The two wizards carefully removed the wooden spike from the patient's arm, fortunately, the wooden thorn did not hurt the bone, but according to the usual experience, with such a severe injury, he would basically die within a few days.

People are curious to see what these wizards will do to save these people's lives, and if they succeed, they will be able to survive if they are injured in the future.

Although the injured person had fainted in pain at this time, and there was no heart-rending scream, the process of pulling out the wood thorns still made everyone worry about it.

After pulling out the wooden thorns, the wizards carefully cleaned the wounds with a high degree of height in a clay pot, and this method of alcohol disinfection was taught to them by Wang Lang.

Although the wound was cleaned, but the wound was still bleeding, a wizard took an unknown weed from the cabinet containing the herbs, crushed it in a clay bowl, applied it to the wound, and carefully bandaged the wound with a boiled linen.

Wang Lang finished reading their treatment methods, and nodded again and again, although this time may not be able to save this person's life, but these wizards' treatment methods are still relatively professional, although disinfection can prevent wound infection to a certain extent, but the effect is not very ideal, thinking of this, Wang Lang called over a wizard and asked, "Where is Qiyan?" ”

"Back to Your Majesty, Qiyan is in the backyard." The wizard replied.

Wang Lang nodded and glanced at the injured man, whether he could survive or not depended on his luck.

With the escort through a door, Wang Lang came to the backyard of the Great Xia Medical Hall, where the wizards lived every day, and in this small courtyard, a young man was carefully observing the animals in the cage, not noticing Wang Lang's arrival at all.

Next to Wang Lang's cages, he saw that these animals had more or less some wounds on their bodies, and most of the animals on their hands were languishing, looking like they wouldn't live long.

"Are these animals used for testing?"

The sudden voice startled Qi Yan, and when he saw that it was Wang Lang, he said: "That's right, these are all animals used to test Penicillium, and you have also seen them, they will die soon." ”

"How do you use those penicillium?" Wang Lang asked.

"I just smeared Penicillium from rotten fruit on the wounds of these animals, but it didn't do much to do so, most of the animals still festered and died, these are increasing the dosage, although it has a little effect, it only delays their death, can this kind of thing you say really save the wounded?"

After experimenting for so long, there was no progress at all, and Qi Yan was a little skeptical that Wang Lang was fooling himself with this kind of thing and letting himself do something meaningless here.

"Don't worry, this thing will definitely work." Looking at these animals that were about to die, he thought for a while and said, "You also said just now, these things can delay the speed of wound festering, it can be seen that this thing is useful, it's just that you haven't found the right way to use it, why don't you change your thinking." ”

"Change your thinking, how do you change it?" Qi Yan asked suspiciously.

"For example, you can try to dissolve Penicillium, maybe something in Penicillium can prevent the wound from festering, you can try all kinds of ways to find out which thing is working, the process may be boring and long, but as long as you succeed, you can do a great work, and it is a great credit to the living." Wang Lang said slowly. Qi Yan touched his chin and thought carefully about Wang Lang's words, he was not interested in any credit, but he was still very interested in specializing in magical witchcraft.

"I'll try as much as I can!" Qi Yan nodded.

"For Penicillium, you can use boiled rice milk to cultivate, just take a little Penicillium and put it in, and after a while it will produce a lot of Penicillium, so that you don't have to bother to find rotten fruits." Wang Lang suggested based on his shallow biological knowledge.

Qi Yan nodded, indicating that he would consider this matter.

For whether penicillin can be isolated, Wang Lang basically does not have much hope, this kind of extremely difficult thing, want to rely on the existing technology to get out, the odds can be compared with winning the lottery.

But even if there was only a 1 in 10,000 chance, he didn't want to give up, after all, penicillin is too important for humans.

As long as penicillin is available, the chances of a soldier surviving in a war will be increased countless times, and as long as he does not die immediately on the battlefield, it is possible to save him, which is very significant for a country with a small population.

Faced with the threat of dinosaur people, Wang Lang racked his brains to improve the odds of his side.

He didn't know how far the dinosaur people had developed in this world, whether the dinosaur people coexisted with humans on other continents, or if they were the only one.

If it is to coexist with human beings, then it proves that the water of human civilization there will not be too low, and if it is the latter, then it means that it is the last hope of human beings here.

Faced with the worst possible situation, he had to frantically click on Xia Guo's technology tree, even if this tree now looked a little malnourished and had a weak foundation, but as long as there was a glimmer of life, Wang Lang was unwilling to give up.

The lack of population, technology to make up for it, is the only way it can think of now.

In addition to this small courtyard, the onlookers have dispersed, and the injured man has also left here, with a glimmer of life given to him by the wizards, and he is tenacious to live.

After inquiring about the treatment of the wizards, Wang Lang left here, he can deal with the affairs of industry and agriculture, but the medical matter, for him, is just a little more knowledgeable than these people, and even in the use of herbs, it is not as good as these wizards, therefore, the medical development of Xia Guo, he completely let go, and handed it over to these people to study slowly, as long as he provides the greatest support.
