Ye Qing glanced at him sideways, and said lightly: "The trauma medicine has naturally been used."

However, Mrs. Ji's illness is equivalent to a woman giving birth once, so she has to find a way to make up for the loss of qi and blood. ”

"I heard that Mrs. Qian is a disciple of the South China Sea Shenni, and she is so talented and intelligent, the old man really sighs to himself." Dr. Zhong said with emotion.

Even though he had some doubts in his heart, Ye Qing was shocked to have such medical skills at his age.

Ye Qing shook his head solemnly and said, "I didn't say that my master is a South China Sea Shenni.

Because when she taught me medicine, she didn't identify herself. So I hope Dr. Zhong doesn't take this seriously. ”

Doctor Zhong said with great certainty: "The gods of the South China Sea travel all over the world, purifying all sentient beings, and it is common for them not to show their identities outside. The old man believed that Mrs. Qian's medical skills must have been passed down from Shenni. ”

"......" The corners of Ye Qing's mouth curled slightly, seeing that he didn't believe his words, he didn't care about these small details, let them be.

Anyway, I didn't say it myself.

Dr. Zhong hugged his fists and saluted, and proposed to go to visit Mrs. Ji with Qian Junbao.

Qian Junbao glanced at Ye Qing and nodded when he saw that she agreed.

Master Zhou had been standing by and listening to them, and he didn't stop Dr. Zhong's request to see Mrs. Ji.

Although Ye Qing saved his sister, after all, his sister's body has not recovered, and he can't guarantee that his sister's body will be fine.

It's also good to have one more doctor to check it out.

This Dr. Zhong came to the door by himself, and he didn't invite him, so he didn't need to refuse the matter of not spending money to see a doctor.

After waiting for two quarters of an hour, Qian Junbao and Dr. Zhong walked out together.

Dr. Zhong stood in front of Ye Qing again, arched his hand to Ye Qing, and sighed infinitely: "Mrs. Ji is no longer in trouble, and she is recovering quickly."

The old man is really fortunate to be able to meet a master like Mrs. Qian. ”

"Don't dare to be, all this depends on the help of my father-in-law, I just did a small thing."

Ye Qing hurriedly stopped Dr. Zhong's admiration and put the credit on Qian Junbao as much as possible.

"Okay, the three of them don't need to be polite anymore, they will all stay in the house at noon today, and the old man has already asked people to prepare the wine and food." Master Zhou walked over at this time and laughed.

I heard that Dr. Zhong and Qian Junbao also said that their sister was fine, and his old heart could be regarded as landing.

During this time, he was anxious and angry, tossed and half dead, and now he is at ease.

In addition, he has obtained a craft of ice making, which is a big deal, and he has to have a good relationship with Qian Junbao and his wife.

"The old man still has something to go back to the hospital, so he won't bother anymore, so I'll leave." Dr. Zhong politely refused, and Master Zhou was not reluctant.

Ye Qing had to wait for Master Zhou's koi fish, so he stayed with Qian Junbao.

During lunch, Ye Qing kept smiling and listening to Master Zhou's praise in different ways.

She is not arrogant or impatient, which makes Master Zhou happy, and of course, the most important diagnosis fee will naturally not disappoint Ye Qing.

In addition to the 20,000 taels, he actually added another 5,000 taels of silver to Ye Qing, saying that it was for her to use more of the master's magic potion to let her sister completely recover her health.

He had heard Zhou Ying say that Ye Qing had some magical potions that she had never heard of, and they were still in expensive glass bottles.

Soon, Master Zhou asked someone to bring a large box full of silver ingots, and the silver light was so shiny that people were happy to see it.

There is a big harvest again, Ye Qing naturally smiled and took it, very good, very good, she likes such a big family.

After the meal, Mr. Zhou asked someone to bring another clay pot, which contained five koi fish with a healthy physique and bright colors.

In particular, the two red and white koi fish have a ruddy and fresh body color, and the white is white and bright.

The body color of the fish is very pure, thick and oily, and it is very valuable at first glance.

"Mrs. Qian, this old man of koi fish has already been brought here according to your request, I wonder if you want to use this as medicine?

The old man has been trading medicinal herbs for more than ten years, and he has never heard of using this fish as medicinal herbs. ”

Ye Qing didn't plan to tell Zhou Yaozu that she didn't want fish to make medicine.

But she still explained with a light smile: "Master Zhou, in fact, this fish can indeed be used as medicinal materials, in addition to eating, it can also be used as medicine."

It has the effect of opening the spleen and stomach, reducing edema, relieving cough and asthma and milking; There are also treatments for maternal milk deficiency or blood collapse; Fish blood can cure crooked mouth and eyes; Bile can cure red eyes, sore and swollen eyes, etc......"

Master Zhou was stunned, and then smiled: "It really has so many effects, it is really a miracle doctor, the old man has been taught." ”

"I don't dare to take the name of the divine doctor, you should call me Mrs. Qian in the future. It's getting late, and it's time for us to go back. Ye Qing got up and said goodbye.

"I'll send you off." Master Zhou followed and got up.

........................

Coming out of Ji's Mansion, they didn't rush back to Qianfu, Ye Qing went to the market and bought a basket of lard and quicklime back, she wanted to try to make a soap.

After asking Dongyun to help boil all the lard out, she studied it herself for an hour.

In fact, any animal and vegetable oil can be used as soap.

Including vegetable oil, sesame oil, soybean oil, cottonseed oil, lard, mutton fat, butter, coconut oil, and many more.

The same principle is the same for any oil made into soap, that is, the saponification reaction of caustic soda and fatty acids.

As for why Ye Qing chose lard, she also had her considerations.

Water + lard + caustic soda is dissolved, heated, boiled, and then glycerol is separated, the soap base is solidified, and then it is put on hold for more than ten days to complete saponification to obtain soap.

But the most valuable thing is not soap, but glycerin.

Glycerin can be used not only to make beauty and skin care products, to make sweet wine, but also to make explosives.

In fact, the ancients also knew very early on about using plant ash and trona to wash clothes, and people also mixed pig pancreas and lard with natural catalytic to make blocks, called "pancreas".

The kind of fragrant pancreas sold outside now was a luxury, until 1791, when the French chemist Lublin succeeded in making caustic soda cheaply by electrolyzing salt, thus ending the ancient method of producing caustic soda from plant ash.

And now, of course, Ye Qing has no way to make electrolytic caustic soda, so she has to use the soil method to make caustic soda.

The easiest way is to add water with quicklime and then add some salt to get caustic soda.

But salt was not cheap in ancient times, and the price of Jianzhou was suddenly reduced to 30 wen per catty some time ago, and in some places in the north, salt still has to be 100 wen a catty, or even 2 or 300 wen a catty.

Because of this, I heard that many officials in the imperial court had opinions on the price of salt in Jianzhou.

Feeling that this made the imperial court collect a lot less salt tax, the government limited the amount of salt sold to the people in Jianzhou.

It is stipulated that each person in this area of Jianzhou can only buy half a catty of salt a month, and he must also buy it with a salt ticket issued by the government.

Even the imperial court will soon issue a new salt decree to prevent salt merchants from using seawater to dry salt, and the price of salt will rise to the previous 100 wen a catty.
