In fact, Zhang Jingyi was not calm either. He was in a state of turmoil all day.

In fact, he himself could not ensure whether the penicillin extracted by the local method was effective.

After all, in order to prevent accidents, Zhang Jingyi gave a very low dose.

Of course, low dose may not be ineffective.

People in this era have hardly used similar drugs and have not developed resistance. To some extent, this dose is already very strong.

The reason why Zhang Jingyi judged that Keshi was only suffering from pneumonia caused by a common cold was actually because he was also confused. After all, he could not perform the test.

The only thing that can be confirmed is that Keshi should not have any incurable symptoms, otherwise how could she jump around in history until after Chongzhen ascended the throne!

The only explanation is that this is just a common cold, and in the end, the condition was delayed because of the wrong medicine, and it was so straight to the point where it was out of control.

Nowadays, a sign of the Qingpingfang Inspection Department is hung outside the Hundred Houses.

The Jinyiwei now has two waist-baring brands, one is the Jinyiwei brand, and the other is the inspection brand. In this way, if the people in Qingpingfang are officials, peddlers, or merchants find suspicious or committing crimes, as long as they are trained by these new recruits and all big and round waists stop them, there will always be a brand suitable for you.

Of course, now Zhang Jingyi proposed to repair the streets, and at the same time, he also asked his father to buy food everywhere.

The money came from the treasure. Lu Xiangsheng personally took people to dig the treasure, and then bought a deserted farm outside, hid the treasure, and then began to sell those miscellaneous valuables.

This treasure is of high value, with a total of 70,000 to 80,000 taels of silver. In this era, a lot of food can be purchased.

The current price of grain is roughly about two taels per stone, and one stone was equal to one hundred dou in the Ming Dynasty, which is about one hundred and eighty kilograms.

The grain harvest last year was actually pretty good. Although there were local disasters, it was not as strong as the world was in ruins. In addition, spring plowing is about to begin, and many gentry families store a large amount of old grain in their barns. Many people hope to sell the old grain from last year before the autumn harvest.

The 70,000 to 80,000 taels of silver, plus the Chen family began to sell the second batch of shops, and the Zhang family tried every means to borrow some money, Zhang Jing could use 130,000 taels of silver to purchase 65,000 stones of grain.

This amount is terrible. It almost emptied the family's six wallets and owed more than 10,000 taels of silver!

And 65,000 stones of grain, this is one million.2 million kilograms of grain, which is definitely an astronomical figure. If ordinary people only eat one kilogram of rice per person, it will be enough to make millions of people full for a day.

But Zhang Tianlun doesn't think so.

It’s not that he didn’t know the importance of food. In this year, food is as important as land, but he emptied his family’s assets and owed debts, but he just kept hoarding food. This was not a good thing in his opinion.

Because grain requires storage costs, and as the grain is stored for a longer time, even if it will not rot for the time being, the price of aged grain is often lower.

He was worried about this, so he came to the hundred households early in the morning and looked at Zhang Jing earnestly and said, "Son, Dad, you know that you are a business person, but what should you do for buying so much food? When the grain is harvested this autumn, the grain will be stored year by year, and the people in our Zhang family are not enough to eat. Speaking of this, I remembered your third uncle again..."

Hearing this familiar name, Zhang Jingyi immediately cheered up: "Ah... Uncle San, how did he die this time?"

Zhang Tianlun: “…”

Looking at Zhang Jingyi's curious baby's appearance, Zhang Tianlun sighed: "It's a long story. Your third uncle was doing business in the capital, but he actually hoarded some sandalwood. He said he would definitely make a fortune. The result... It was a terrible thing, and he lost all his money. Later... in order to avoid debt, he slipped out of the capital, not knowing whether it was death or life."

Zhang Jing nodded: "Uncle San is really a talent."

Zhang Tianlun said, "Don't learn from him."

"It's just a matter of buying food, and you still need your father..."

"What do you want to buy? Can my father still stop you? This is the money you earn. I just hope you don't repeat the mistakes of my third uncle." Zhang Tianlun continued worriedly: "However, buying rice is the most cost-effective at this time. There are many rice merchants in the capital. Many people want to ship and emptie their own rice warehouses. When it comes to the autumn harvest, buy new rice and walk more for your father. Don't think that this thousand households are useless, but you still have a face."

Zhang Jingyi could only nod.

After seeing off Zhang Tianlun, Zhang Jing started reading books boredly. It is beneficial to read more books from this era. At least you can know the preferences of scholars from this era.

At noon, an eunuch hurried over: "Where is Zhang Baihu? Your Majesty summoned him, Your Majesty summoned him, please..."

At this time... Zhang Jing understood that Keshi's disease had a result.

It was fake to say that he was not nervous, so he quickly asked, "How is it, is Madam okay?"

The eunuch was obviously very anxious to ask Zhang Jingyi to enter the palace quickly and said anxiously: "Let's enter the palace first."

So Zhang Jingyi quickly followed the eunuch into the palace.

It was only then that I realized that the medicine had taken miraculous effects.

The journey was smooth, and as soon as Zhang Jing arrived at Cining Palace.

In this bedroom, when Emperor Tianqi saw Zhang Jingyi coming, he immediately said happily: "Zhang Qing, Zhang Qing... Come quickly... Come..."

Wei Zhongxian also said: "Yes, Zhang Baihu, come and have a follow-up visit, see your sister-in-law... see how our wife is sick."

Every time Wei Zhongxian makes a mistake, he hates himself deeply, as if he has been washed by someone's head, and can always say some inappropriate words.

Zhang Jing nodded slightly and immediately entered the bedroom. Then he saw Ke Shi, who was refreshed at this time, lying halfway against the head of the bed.

Keshi has already drunk a bowl of porridge and two osmanthus cakes.

The whole person's spirit began to rejuvenate, and his face became much better visible to the naked eye.

She heard that it turned out that a hundred households named Zhang Jingyi saved her. When she saw Zhang Jingyi coming to her, she was so young. Her first thought was, has this kid got married?

Under the attention of countless people, Zhang Jingyi began to take the pulse of Keshi.

However, he didn't know how to take the pulse, but he still had to pretend. In fact, in this case, the disease should be developing in the direction of cure.

Of course... Zhang Jingyi rescued Keshi, not because his bones were itchy, so he had to find someone to refine medicine.

But... he planned to fetch the wool.

Keshi is a very strange person.

She is not only the emperor's spiritual support, but also the person in the harem who stomps his feet and makes people tremble.

And the most interesting thing is that during the entire Age of Qi Dynasty, everyone wanted to pull her wool.

Just say that Wei Zhongxian, the nine thousand years old, climbed her to this day.

Even Huo Weihua, who gave the immortal medicine, actually wanted to take the opportunity to grab it. After all, although the immortal medicine is not reliable, what if it can really cure the disease?

The same is true for Zhang Jingyi, he has very important things to do.

"Well..." Zhang Jing took Ke Shi's pulse as if nothing had happened, and nodded with a hint of relief: "This disease has been cured, at least his life has been saved."

Zhang Jingyi's words now... are still quite authoritative.

Emperor Tianqi was overjoyed, staring at Zhang Jingyi as if he was emitting light, and said gratefully: "If it weren't for Zhang Qing's family, the wet nurse would be afraid... if there was an accident, Zhang Qing would still see a doctor?"

Zhang Jing started talking nonsense: "I met a master who learned a few skills, but..."

He couldn't say it...

Everyone's hearts were in their throats again.

Especially Keshi, she walked through the gates of hell, and she had a strong desire to survive at this time. Zhang Jingyi's words made her almost faint.

Wei Zhongxian said anxiously: "Brother Zhang, what's going on?"

At this time, I couldn't even care about the problem with the title.

Zhang Jingyi said seriously: "Brother Wei, I don't know whether to say something or not. My sister-in-law's symptom is a strange disease. Now I just rely on this magic medicine to temporarily stabilize the condition, but I can't cure it. It's like... leeks... leeks?"

"Leeks?" Emperor Tianqi and Wei Zhongxian looked at each other.

Is it related to illness and leeks?

Zhang Jing said: "This leek... After you cut one crop, it will grow another crop, endlessly and endlessly!"

"Oh." As smart as Emperor Tianqi, he nodded quickly: "This... I understand, I understand, but what does this have to do with illness?"

"The same is true for this disease. Now it has suppressed a certain disease in the body. But after a few months, if you don't use medicine, you may have to grow again. At that time, you are afraid that your life will be in danger and it will be difficult for the gods to save you."

This is really scary.

Keshi almost fainted.

Emperor Aoki couldn't help but say, "What should I do?"

Zhang Jingyi said: "In fact, it's easy to deal with. After a few months, you can just use the medicine. As long as you take the medicine on time, it will definitely not recur."

Emperor Apocalypse: “…”

Zhang Jingyi obviously planned to use Keshi as a leek.

As for giving her injections every now and then, of course, she did not use penicillin in the medicine, but just ordinary distilled water. Even Zhang Jingyi planned to make glucose in the future, just to treat it as a nourishing person. If she is sick, she can strengthen her body even if she is not sick.

Of course, one of the reasons why he claimed that the disease would last forever was that Zhang Jing wanted to buy himself a talisman first.

Aren’t you Wei Zhongxian very capable? Come on, you have a gossip to beat me, a fool. If you Wei Zhongxian doesn’t want Keshi to die, you don’t want to kill me.

On the other hand, Zhang Jingyi has other plans.

At this time, everyone couldn't help but breathe a sigh of relief after hearing Zhang Jingyi's words. After all, although it was troublesome to continue taking medicine, as long as they didn't die, it would be a great joy." But... "Zhang Jingyi immediately became embarrassed.
