Loose on the outside and tight on the inside, this is the current state of the Great Song Dynasty, although the whole country is preparing for the coming battle of Liao, but the people who really know about it are limited to a few, even those soldiers who were transferred to Hebei, they only know that they are ordered to change the guard, and they don't know that they are about to participate in a major event that changes history.

Li Zhang, as the behind-the-scenes promoter of this matter, during this time, in addition to taking care of Qingzhi at home and Miao Yuan outside the home, most of the time was also spent on medical school, mainly because he didn't dare to enter the palace to see Zhao Zhen, for fear that he would be too weak and show abnormalities, plus the medical school has officially opened, he, the mountain chief, naturally has a bunch of things to deal with.

"Mountain Chief, can these really work?" Zhou Zheng looked at the bottle of moldy liquid in front of him and asked with a sad face.

"Not now, because I can't purify these things, but someone has to do these things in front of me, maybe someone will be able to think of a way to purify them in the future, and then there will be a life-saving medicine in this world." At this time, Li Zhang straightened up and looked at these cultivation channels in front of him.

Although he knew that penicillin was a good antibiotic and had a good therapeutic effect on diseases caused by many kinds of bacteria, he did not know how to purify it, and penicillin should not be taken orally, so it could only be purified and injected, which was too difficult for Li Zhang.

Zhou Zheng still didn't understand Li Zhang's words, because he really couldn't see how these moldy things could cure diseases? But since Li Zhang said it, he can also choose to believe it.

In fact, Li Zhang also sighed a little secretly at this time, because the microscope he developed had not yet succeeded, and the glass had already been burned out, and after adding lead, the transparency had also been reached, and the polished lenses were quite good, and the principle of the microscope was not complicated, but it would take time to make it, otherwise he could let Zhou Zheng see the microscopic world.

However, even with a microscope, it still did not help much for the practicality of penicillin, and I remember that it took more than ten years from the discovery of penicillin to the real practical use in later generations, and the basic science of this era was so poor that he couldn't start purifying penicillin, which was one of the main reasons why he planned to promote education.

At this moment, I suddenly heard a rush of footsteps outside, and then I saw a teaching assistant shouting with surprise on his face, "Mountain Chief, wake up, that prisoner is awake!" ”

"Great, let's go check it out!" Li Zhang and Zhou Zheng also showed excited expressions when they heard this, and immediately followed the teaching assistant out of the room quickly, and then came to a large courtyard behind the college, which was changed by Li Zhang to look like a hospital, and some medical research was also carried out here.

At that moment, Li Zhang and Zhou Zheng rushed into a ward, only to see a bald man lying on the bed, although the skeleton is very large, but he is yellow and thin, and he looks half-dead, but at least now he is awake, and at this time he also looked around with his eyes open, and when he saw Li Zhang rushing in, he showed a look of fear, even if his limbs were tied, he began to struggle desperately at this time, it seemed that Li Zhang was like a demon in his eyes.

"Be honest, I'll have to help you sew it up again after breaking open the wound!" Li Zhang saw the appearance of the other party and immediately scolded, this bald head is a murderous Jiangyang thief, there are no less than twenty lives in his hands alone, and he has already been sentenced to be beheaded by the Autumn Queen, but Li Zhang asked him to come over as an experimental material.

The reason why this guy was chosen was not just because he was a death row prisoner, but because this guy was already sick, and it was also an intestinal carbuncle, that is, appendicitis, although it was chronic, but it also tossed this guy half dead, in line with the principle of waste utilization, Li Zhang asked him to come to do experiments, a few days ago he removed his appendix, and used all measures that can reduce inflammation, but this guy's life was quite hard, and he woke up after two days in a coma.

Hearing Li Zhang's words, the bald thief immediately didn't dare to struggle anymore, because when Li Zhang operated on him before, it may have been that he gave less anesthetic, or it may be that this guy's drug is relatively strong, but he woke up halfway through the operation, and he also saw Li Zhang cut open his stomach, and took out something from it, and finally sewed his stomach back, which is like walking in hell for the bald thief, and Li Zhang is a demon who digs people's hearts and eats human flesh.

Li Zhang didn't care what happened to this death row inmate, anyway, even if he was cured, this guy would eventually be pulled to Dongshikou and slashed, so he walked quickly to the death row inmate, lifted the quilt and looked at his wound, and found that there was no sign of inflammation in the stitched area, which made him also relieved.

"Miracles! What a miracle! Mountain Chief, you actually cured his intestinal carbuncle, this is a terminal disease! Zhou Zheng also stepped forward to look at the other party's wound at this time, and then shouted in surprise, although Li Zhang had also done some surgery on animals before, but in their opinion, animals are animals after all, completely different from people, and this case made them more confident in the operation.

"This is nothing, we still need to do more surgeries, sort out a set of experience and systems, so as to ensure the success rate of the operation, in addition, you also have to practice more, and you can be the main surgeon when you have the opportunity in the future!" Li Zhang also smiled at this time.

In fact, Li Zhang is not modest, this time when he operated on the bald thief, he felt that he was still not fully prepared in many aspects, just to show Zhou Zheng and others the effect of the operation, so he forcibly did the operation, Li Zhang was ready to fail, but he didn't expect that although this thief had been tortured by illness for so long, the foundation was still there, and it was his luck to survive.

Zhou Zheng They don't think that this is Li Zhang's luck, they only think that Li Zhang is modest, and with the living examples in front of them, they have a greater enthusiasm for surgery, and even can't wait to have the opportunity to operate as soon as possible, after all, surgery and treatment generally only exist in legends, and it is also the unique skill of the divine doctor Hua Tuo, but they didn't expect that they would also have the opportunity to learn.

At that moment, Li Zhang was about to do a detailed examination of the bald thief to see how he recovered, but at this moment, someone suddenly came to the palace, and it turned out to be Zhao Zhen who summoned him into the palace, which made Li Zhang suddenly feel a little weak, after all, as time went by, Miao Yuan's belly also grew bigger day by day, and this kind of thing would be known by Zhao Zhen sooner or later, and he would call himself into the palace now, wouldn't he already know about it?
