Since this is the case, then the 'medicine' that Zhang Jingyi tossed here is useful.

Tinkering with this medicine was actually the first thought that flashed through Zhang Jingyi when she came to this world.

Because, even if he came to the end of the Ming Dynasty, even if he really built a slave to enter the customs like history, then he could at least jump for nearly twenty years.

But the level of medical care in this era is life-threatening.

Think about it, any minor illness may be a terminal illness, that is, the emperor and those dignitaries and nobles cannot ensure that their children have a survival rate of eighty percent, if he is in this era, not to mention, there is no vaccine, that is to say, any illness, for him, it is a ghost gate.

In such an environment, he has a huge sense of crisis.

Therefore, Zhang Jingyi has been tinkering with pharmaceuticals.

At present, with this limited condition, the only thing that can be tried is to use the soil method to extract penicillin.

You know, when penicillin was first born, it was almost equivalent to a panacea, and in later generations, this medicine could solve at least seventy or eighty percent of diseases.

If he can toss this, Zhang Jingyi will almost have a layer of protection in this era, unless he encounters an incurable disease or a cancer that makes people talk about tiger discoloration.

However, the local method of extracting penicillin is actually a very risky thing, although the principle is very simple.

First of all, for ordinary moldy things, such as fruits, vegetables, etc., of course, this thing is unreliable, Zhang Jingyi first tried, put the orange peel in a moist place, and waited for the orange peel to slowly rot, giving birth to green hair, this so-called green hair, in fact, is the legendary Penicillium.

Of course, it is obviously wishful thinking to directly expect such a thing to cure the disease.

The next thing you need to do is to carefully collect the Penicillium and make sure that it doesn't become contaminated.

The best way is to spend a sky-high price to buy a crystal container, crystal is very expensive, and to make a vessel as transparent as glass with crystal, the price is even more expensive.

Of course, Zhang Jingyi still has some financial resources today.

After that, it is time to build a culture medium, which is made from the juice of taro boiled and mixed with rice juice, and then the collected Penicillium is planted.

In this way, these penicillium are equivalent to rats falling into the rice jar, just waiting for them to reproduce.

After a week, more and more Penicillium had multiplied in the medium.

And then the most difficult part is the extraction of Penicillium.

After all, this Penicillium is mixed with the juice, and how to purify it is not an easy task.

Therefore, the first thing to do is to use a funnel to filter out the rice residue in the culture medium, and then pour vegetable oil into the liquid, then stir well, then add toner, and continue to stir.

These toners will be absorbed by Penicillium, which will be dissolved in distilled water, and then acidic water made of vinegar, which is a weak acid and will not be dissolved in acidic water, so Penicillium will be dissolved in the toner.

That's the way it is, in theory.

Of course, it's hard to do.

Every process must be careful and careful.

Just half a month ago, after a series of inversions, Zhang Jingyi finally got some penicillin.

Of course...... It's not the hardest way to get penicillin out of this way.

The most difficult thing is how to ensure the safety of these penicillins.

Because of this home-grown penicillin, you can't be sure if they've been contaminated during the refining process.

Even Zhang Jingyi couldn't confirm whether it was Penicillium that could cure the disease.

After all...... There is no microscope.

God knows how many impurities there are in it, penicillin needs to be injected, just such a thing of unknown origin, injected into the human body, just afraid that the disease has not tortured people to death, this thing has killed people several times.

So...... The most difficult thing is to experiment with the soil method.

And so these young doctors came in.

Zhang Jingyi asked them to do only one thing.

That's looking for rabbits.

Hurt the rabbit first, then trigger their inflammation.

Finally, a syringe is made to inject a small dose of penicillin into the rabbit's body.

This has two benefits, if the drug is effective, then the effect of different doses can be tested.

If this drug is a bad deal, at least there is stewed rabbit meat to eat at night.

It turned out that Zhang Jingyi was lucky, extracted penicillin, effective.

At least...... The inflammation heals quickly, and the side effects are not obvious.

Of course, this is mainly due to Zhang Jingyi's best efforts to reduce the dose to the minimum, otherwise if he uses the same dose as in later generations, Zhang Jingyi guarantees that everyone will have four meals of rabbit meat every day.

After confirming that the medicinal properties were effective for rabbits, it was time to find someone to try it.

Zhang Jingyi does not like such experiments, because people are people, rabbits are rabbits, rabbits can stew soup, and people are priceless.

There are many people in the capital who are seriously ill but have no way to treat them, and in the past few days, there are such patients, after promising that the medicine will be free of charge, and if there is any accident, they will make a large amount of compensation, it seems that some people also take the initiative to ask for help.

After all, they could have died in the first place.

At least there is still a glimmer of hope to live, and even if he dies, he can still leave a large amount of compensation to his family.

These little doctors, who were recruited at first, were very speechless.

The most important thing for doctors is to find someone to see a doctor, and the more patients they see, when their beard grows again, and even the beard will slowly turn gray in the future, and from then on, they will be able to enter the door independently.

But Zhang Jingyi locked them in the hospital every day and tested the medicine again and again, which made them suspect that this Zhang Baihu must be doing something evil.

It wasn't until a dose of penicillin was injected into a patient with severe lung disease as it had been on rabbits, and a few days later, the patient, who was almost dying, was able to start jumping up and down all at once...... The young doctors were excited.

Is...... Miracle medicine.

To know...... How many people have to rely on their bodies to carry such a disease, if they can't resist it, their condition deteriorates, and they can only wait for death.

But this medicine has a great effect.

The doctors began to get emotional.

What doctor doesn't want to be able to carry a miracle medicine on his body to treat people?

So they gave medicine to many patients again and again, and then recorded various data according to Zhang Jingyi's method, and observed the different reactions of patients according to different doses.

It wasn't until Zhang Jingyi came to the door this time that he left with some penicillin.

In fact, every time Zhang Jing comes, it is an opportunity for young doctors.

At first, when he came, everyone was nervous and silent to each other, as if they were passers-by.

But now, there are many young doctors rushing over, some report data, and some are asking if this medicine can cure what diseases, in their opinion, Zhang Baihu, who made this medicine, is simply a miracle doctor in the world, such a special medicine, only in legends have been seen.

Zhang Jingyi was too lazy to pay attention to them.

I'll tell you everything, so what will I eat in the future?

Church apprentice, starve to death master, do you really think that I, Zhang Jingyi, am two and don't leave a hand?

In fact, I just use you as a tool, and I will talk about other things later.

With penicillin in his hand, and a doctor's standard medicine box, oh yes, and the list that has been revealed.

As soon as Zhang Jing arrived at the noon gate, he then asked for an audience.

Immediately, Zhang Jingyi was sent to the warm pavilion.

Emperor Tianqi actually doesn't usually like to come to the Warm Pavilion, which has long been in disrepair, and he prefers to stay in the Qinzheng Hall in Xiyuan.

And now, Wei Zhongxian has already run to the Emperor of the Apocalypse and began to add fuel and vinegar.

There was another person who came with him, Huo Weihua, the right attendant of the military department.

Huo Weihua is the guy who gave Wei Zhongxian the "Spirit Dew Drink" that kind of elixir, although he is a squire in the military department, but he claims that he has a family history, a whole room of medical books at home, and an ancestral secret recipe.

In fact, Huo Weihua in history, when the Emperor of the Apocalypse was sick, he also took this 'Linglu Drink', and then ...... Then this Huo Shilang killed the Emperor of the Apocalypse after falling into the water and getting sick.

Only now, he is ruling the Holy Lady Hakka.

In a sense, the Hakka family is now sick like this, and Zhang Jingyi is responsible. It was because of Zhang Jingyi's timely rescue that the Emperor of the Apocalypse did not fall ill because of falling into the water, and Huo Weihua's immortal medicine naturally did not give the Emperor of the Apocalypse to eat, he did not kill the Emperor of the Apocalypse, and naturally maintained the character of holding the immortal medicine, if it were not for this, he would not have had the opportunity to sacrifice the immortal medicine after the Hakka family fell ill this time.

Now Huo Weihua heard that Ke's condition was aggravated, and he was very anxious, and he originally wanted to make a good contribution with the immortal medicine, but where did he think that he might have to carry the black pot!

So he found Wei Zhongxian again, saying that this must be that the dose of the immortal medicine is not enough, and the dose needs to be increased, and his father-in-law must not look for those who are not indiscriminate to treat the disease.

Wei Zhongxian was also a little hesitant, so he reported the matter to the Emperor of the Apocalypse.

"Zhang Qing's family has unveiled the list?" The Emperor of the Apocalypse was so surprised that his eyes were about to fall off.

Isn't this full and holding on?

"Your Majesty, this Zhang Jingyi is a Jinyi guard, what does he know how to save people? Their Zhang family has no family history, and Your Majesty must not mistake people's words. Huo Weihua took the opportunity to say.

The Emperor of the Apocalypse was already irritable, and in the early morning, Mrs. Fengsheng coughed up blood, and if she continued like this, she was afraid that her life would not be long.

Originally, I thought that Zhang Bang was seeking talent, and he could find a reliable person to come, but who knew that the doctor who was serious had not been recruited, Zhang Jingyi actually came to join in the fun, and he was afraid that he had not yet understood the matter of treatment!

At this moment, a small eunuch cautiously came in and reported: "Your Majesty, Zhang Baihu is here." ”

"Just speaking of him, call him here." When the Emperor of the Apocalypse heard Zhang Jing coming, although he was anxious, he was also in a calmer mood.
