"Oh! How many times have I told you, it's written in the book. Once someone else is sick, you should be more careful and don't be intimate with them. Tell me, are you being unruly?" Wang Yang was in a bad mood.

"I didn't! I also paid attention and didn't do anything with them." The man looked innocent.

Hearing what he said, Wang Yang had no choice but to do it. It seemed that this was the worst case scenario, and he was accidentally infected.

"Are any of you seriously injured?" Wang Yang wasn't sure whether it was a simple cold or something else.

"One is dead," the man said.

Wang Yang patted his forehead, feeling that the sun was too strong today and he felt a little dizzy.

"Then why are you back now? It's been so long and you haven't recovered yet?"

"It's not that we didn't. We felt better for a few days, and then we felt bad again. Over and over again, we just couldn't get better." The man sniffed his nose at the right time, wiped it with a handkerchief, and put it back in his pocket.

.

"How can you put it back in your pocket? Wash it in the water quickly, and then dry it in the sun. Forget it, there is no need to dry it. All the clothes you have worn during this time have been burned. I will have someone give them to you.

Send me some new clothes."

After speaking, Wang Yang told Zhang San on the side: "Place them up, each in a room, and isolate them all to avoid repeated infections."

"Also, for the recent diet, give them something light to eat, drink more boiled water, dispose of excrement as early as possible, don't have too much contact with others, and let them run and sweat every day." Wang Yang could think of something.

That's all.

After giving the instructions, Wang Yang still felt restless. Why did he get involved in such a thing? It was really a headache.

He came to the science laboratory and found the scientists. As soon as he came in, he said: "Is there any progress in the drug I asked you to study?"

Wang Yang asked these scientists to study drugs. And it was a drug that could treat many diseases, penicillin.

If you want to understand penicillin, you need to understand what penicillium is. Thanks to the guy who discovered penicillium in his previous life, he found it from a rotten orange.

When oranges rot, green or white mold will grow, which contains penicillin.

And this kind of penicillium will not only grow on oranges. If the flour is left out for a long time, it will also grow. White hairs will grow on it, and other fruits will also grow on it.

"There is no progress, we don't know how to get it." Scientists are simply at a loss. They have no way to study this kind of thing.

They took Wang Yang into a backyard. There were pots of paste in a sunny area. The paste was very thick. About two centimeters of white hair grew on the surface.

A sour and festery smell hit Wang Yang's nose directly.

Historically, as early as the Tang Dynasty, some people actually discovered the effects of penicillin. They also took batter and left it for a period of time, then cut off the white hair on it and used it to treat diseases.

But this prescription is a folk prescription. What is a folk prescription? It is a dangerous prescription that has not been approved. It may kill people.

Wang Yang stepped forward and touched the white hair. He felt that it was very soft. The hair contained penicillin.

But if it is used to treat diseases, eight out of ten will die, because the ingredients in this hair are not pure and contain many deadly germs.

"We conducted experiments on many animals, especially those that were destined to be slaughtered or came back from hunting with large wounds. We covered their wounds with white hair, and the results were that the animals that survived were ten years old.

Less than one.”

In modern times, penicillin is very likely to be given when you have a fever, but it is also an anti-inflammatory drug. You can try applying it to the wound (one of the methods, not recommended).

Therefore, it can be said that if penicillin can be developed, there will be medicine for wounds, colds and fevers.

Infection of wounds is the biggest cause of injury and death in this era.

The problem now is how to separate the damn penicillin from these bacteria.

Just such a problem stumped everyone.

"Continue to do experiments, such as trying the tip of the white hair to see which part has the highest success rate."

Treating a dead horse as a live doctor, this is the current situation, although Wang Yang also knows that it is of no use.

But as long as there is a glimmer of hope, it is worth trying. Anyway, he said he would never give up.

"Also, you go and study how to ferment, ferment and make wine for me, and make alcohol!" Wang Yang gave an order, and these scientists designated a direction.

If you can't get penicillin, first get some medical alcohol that can reduce inflammation and kill viruses.

The dozen or so people who were sick did not know whether they really had a cold, so they were isolated by Wang Yang. They had to open their rooms to ventilate them and drink boiling water every day.

When I was confused, I had to run and sweat, and I had to use only one pair of bowls and chopsticks to eat, so I couldn't eat with others.

The people who came to take care of them also had a new tool on their faces unknowingly, a mask...

Everyone knows that they are patients, and they also know that it has been written in the books that they should stay away from patients, especially when the cause of the disease is not sure.

They feel isolated, very lonely, and anxious to recover from their illness.

On this day, Wang Yang came. He also wore a mask and asked several people to sit down while they took their pulses.

He doesn't know how to take pulses, nor can he, but he can learn to feel their pulses carefully for five minutes.

Then I checked the pulses of other healthy people, and it was still obvious that one was weak and the other was strong.

But that's all. There are dozens of pulse conditions, and he hasn't figured out the specific feeling yet.

He wrote down what he felt on his phone very seriously, and then he frantically took everyone's pulse like he was possessed, but no one knew why.

Ask him: "Why are you touching your wrist?"

Wang Yang said: "There is a pulse in your hand, and you can feel it from here whether you are healthy or not."

Not only that, he also looked at people's tongue coating and pupils, doing it desperately, like a madman.

Unfortunately, the experience summed up is very little. I guess the talent for studying medicine is not good, and there is no one to give guidance, so there are not many useful things written down.

But no matter what, he still tried his best to learn on his own, and he was able to distinguish a few things.

Most of those people have recovered from their colds and are in good health. There are two others who have not recovered. These two are new people. They have been frozen for a long time in the past. They may have suffered from severe cold diseases. In addition, their bodies are not strong enough and their immunity is too weak.

.

With these two people, Wang Yang really had no choice but to describe their illnesses and use pictures to ask them about their feelings.

The two of them were very touched and excited. Good guy, the architecture of this place was really an eye-opener for them, and seeing Wang Yang caring about them so much, even though they didn't know who Wang Yang was, they were still very moved.

After I came out, I felt that time was running out and I had to put medicine into practice as soon as possible.

And the matter of finding someone seemed very urgent.

On this day, he brought a few people to the forest, intending to look for any medicinal materials he knew. No matter what kind of plants they were, as long as they looked strange, he would dig them all.

Watching the birds flying back and forth in the sky at extremely fast speeds, soaring in the sky and jumping on the branches, Wang Yang sighed.

"It's better to be a small bird. When traveling between two places, you don't need to be blocked by mountains and rivers. They fly in a straight line. They don't need to go uphill and downhill. They can travel over a hundred kilometers of mountainous terrain quickly."

Fly over."

"If people can travel back and forth unhindered like birds, even if they build a station every month, what do they have to worry about?"

Wang Yang was helpless in wanting to come here. It seemed that the history he had learned did not bring much help to him.

In ancient times, inns were also used as temporary communication points to forward communications. There were well-raised horses in the inns, so that they could travel eight hundred miles a day, which was the so-called eight hundred mile express.

It's a pity that their roads have been built. Of course, it's impossible to build the roads myself. How much time will it take?

Is there no other way to communicate in ancient times? Wang Yang thought about it for a moment, then suddenly he blurted out: "Flying pigeons send messages!"

In ancient times, information was not only transmitted through people, but also through pigeons. This is the famous flying pigeon to convey messages.

However, everyone has heard that it seems that it is not possible to use it on a large scale.

So what is not used on a large scale? Flying pigeons are obviously good for delivering messages, because pigeons take the way of heaven, not waterways, nor roads.

People's "air force" has no obstacles in the sky, can't it shorten the distance? Moreover, pigeons fly very fast, and pigeons with good physical strength can fly a long distance in a day.

It should be said that using pigeons to convey messages is a matter of getting twice the result with half the effort and has many benefits.

Moreover, pigeons naturally have extremely strong magnetic field induction, as if they have a compass inside their bodies, and they have a very good sense of direction.

Since it was not used on a large scale in ancient times, does it mean that there are still flaws in using flying pigeons to deliver messages?

Or, it may have happened, but it still failed.

Wang Yang didn't want to think about the ancient reasons. Now he only had this idea. If he used flying pigeons to deliver messages, would it be...

Once this thought arose, he could no longer suppress it. He glanced around and glanced at the birds with burning eyes.

There are countless animals like pigeons, which can be found all over the world. He is not afraid of not finding them. In this case, he has an opportunity to take advantage of them.

You can try it out.

On this day, he picked a lot of unknown plants, and immediately after returning home, he had people label and name these plants.

Then he took a plant that might be a medicine, separated the leaves and roots, made a bowl of soup each, and brought it to the two patients.

"Life and death are destiny, wealth and honor are in heaven. I don't think you two will be well for a while. If you want to drink, you can try it."
