Zhao Huan's dowry to Master Li was not five thousand taels of silver, he gave Master Li a recipe for emulsifying wool.

The original wool on the sheep's body, in the Great Song Dynasty, was useless.

When sheep were slaughtered, wool was a discarded thing in the Great Song Dynasty.

This is due to the fact that the wool is raw wool, mixed with various physiological impurities and dirt in the living environment, which is dry, hard and smelly, and cannot be directly woolen.

Wash wool twice, the first is soaphorn, wool is not alkali resistant, soaphorn can wash off lanolin.

But the wool at this time is still unusable.

There is no shortage of smart people in the Great Song Dynasty, and it is not that no one has thought of using wool, but most of them have stopped at this point, because the wool at this time is not pure in color, and the broken leaves of the grass thorn leaves are left in the wool, and they still cannot be spun.

Pulling out the leaves of the grass thorns, the wool is strained, and the process is complicated, and the labor cost is high.

Abandon it, naturally there is a reason to abandon it, not that the Great Song Dynasty people did not think that wool can keep out the cold.

This second, most critical process is the use of a sulfuric acid solution to carbonize these leaves and grass thorns.

And sulfuric acid can be obtained by calcining alum, and the alum oil obtained is sulfuric acid.

Alchemists used green alum as an ingredient in the elixir of life, which gradually evolved into medicinal use.

But its biggest role is the basis of chemical industry, sulfuric acid in three acids and two alkalis.

Master Li read the letter and saw that Fang Zi was still confused, and after thinking about it for a long time, she suddenly realized the purpose of this recipe.

However, Master Li still didn't speak, and finally sighed and said to Zhao Ying: "The trouble is all known to go back to the official's house, and the master knows what to do." Do things for the official family, and the concubines will do their best. ”

Master Li knew the meaning of the official family, that is, this emulsified wool and the products after it were all business in the palace, and from now on, she would be an imperial businessman.

Zhao Ying left the inn in a daze, Cui Kui'er's answer to Zhao Ying was that she refused to enter the palace, and Zhao Ying did not twist the melon, so she rushed back to the palace to resume her life.

Zhao Huan heard Zhao Ying's report, the pen in his hand paused, and said: "A maid refused to enter the palace as a singer, doesn't she know that she can get out of prostitution if she enters the palace as a singer?" ”

Zhao Ying filled the official's family with tea and said: "The minister said, she defected to Li Xuanyi before and entered the prostitution, if she enters the palace to be a palace maid, she can get rid of the prostitution, the minister has also seen it, she is a chick." ”

"But Cui Kuier said that Li Xuanyi has a great kindness to her, and she will not give up in this life."

"It's a good person who knows how to repay his kindness." Zhao Huan nodded, but he immediately realized something, and asked: "Zhao Duzhi, your eyes are quite poisonous, you can see that someone is a chick." ”

"The ministers and the previous flowers and birds made to learn, there are not many eunuchs under the official family, and the responsibilities of the flowers and birds have been borne by the ministers since the official family ascended the throne, and they have learned a hand. The official family, everyone Li is also a chick. No, now it should be called Li Shanggong. Zhao Yingle continued.

Lee: Everyone? Li Qingzhao?

Zhao Huan finally put down the pen in his hand, when Zhu Lian asked for Li Qingzhao to enter the palace to talk to her, he felt that something was not right.

The word Gong Yan, where can you say that you can enter and enter?

At that time, the war situation was urgent, and Zhao Huan was in a hurry to go on the expedition without thinking much about it. Now that I think about it, there is a problem.

"Does Concubine Zhu also know about this?" Zhao Huan asked.

Zhu Guifei asked the old palace maid of the Queen Mother. Zhu Guifei also asked the minister to mention this matter in front of the official family. Concubine Zhu thought that the official family had some prejudice against Li Shanggong. Zhao Ying replied.

He deliberately provoked this remark, and the purpose was to pass on the word to Zhu Lian.

"I see." Zhao Huan picked up the pen in his hand, but he didn't approve the notebook, he wanted to ask the system about this.

"System! Is Zhao Ying reliable for this? Zhao Huan waited for the system's response.

[This feature is not loaded, is it listed as a post-upgrade loading feature?] 】

The system's answer was not unexpected by Zhao Huan, he was used to the uselessness of the system.

"No! Not! Not! I can't load it without a function that I use. What do you say you want you to do? Not even a eunuch. Zhao Huan scolded with a smile, ready to continue to review the notebook, this matter is not in a hurry, and he will always know it slowly.

[According to historical data, Zhao Mingcheng had no children in his life. In the "Tales of Yuyin Cong" written by the Song people, it was said that Zhao had no heir, and Li was even more married. And the author of this codex is Hu Zai, one of Zhao Mingcheng's few friends, which can be slightly corroborated. 】

[The system is neither male nor female, not eunuch, please know the host. 】

Zhao Huan was silent for a moment and asked, "Then what are you?" ”

……

Master Li continued to go south with Zhao Huan's zizi, and when she arrived in Huaibei, she did not pause, and actually went straight to Huainan.

Next to Huaishui, Master Li's car stopped in an extremely well-located place, where a lonely grave stood alone.

This is the grave of Cui Kui'er's parents, Cui Kui'er was originally a branch of the Cui family in Huainan.

Her father failed the exam many times, and her mother sold her property to support her father's exam, and as a result, Cui Kuier's father died on the way to Bianjing.

Cui Kui'er's mother was still extremely young at the time, and the eldest son in the clan drank high, intending to desecrate Cui Kui'er's mother.

Cui Kuier was not young at the time, she deeply remembered how the eldest son of the Cui family, who was in the heavy rain that day, with the smell of alcohol on her body, her eyes were full of madness, and her hideous face was how she bullied her mother.

Then her mother hanged herself in tears, and the young Cui Kuier stepped on the chair on the table, only to cut it with scissors and put her mother, who had already died, on the ground.

Cui Kuier dragged her mother's body and went to the Yamen of the Bozhou prefect to sue the official, but the Cui family, whose clan law was greater than the national law, chose to deal with it with family law.

Of course, it was not the eldest son who disposed of the lineage, but drove Cui Kuier out of the lintel of Cui's house.

At that time, Master Li, who followed Zhao Ji Nanxun, was in the prime of jasper and turned eight, and when he saw Cui Kuier crying in the heavy rain, he accepted Cui Kuier as a maid.

After burying Cui Kui'er's mother, Master Li also relied on his own favor to let Zhao Ji help his maid vent his anger!

Where does Zhao Ji dare or not?

It's just that what made Cui Kui'er even more devastated was that Cui Fu naturally obeyed the emperor's order, so he ordered the eldest prince to go to the grave to deduct his head and apologize.

After all, it was a family affair of Cui Mansion, and Cui Kui'er's mother committed suicide.

The eldest prince honestly went to kowtow, but what made Cui Kui'er's eyes tear was that the eldest prince took his mother's dirty clothes and burned them in front of the grave.

The eldest prince said in a weird way that he wanted to be pretty, he was filial, and even his clothes were white, and he didn't hold it, so he forgave him for being rude.

Cui Kuier will never forget that scene, the evil smile and banter on the face of the eldest son.

Cui Kui'er has not come to sweep the tomb for five or six years, and this time Master Li entered Huaibei without stopping, and came directly to Huainan, just because Cui Kui'er wanted to give her parents a pillar of incense.

"The Cui family is gone, all the doors are beheaded, and all of them are completely dead, and there are only a few remnants left in the Jin Kingdom!"

"Father, Mother, you can look at it!" Cui Kui'er cried loudly, and Master Li hugged Cui Kui'er's head, and two lines of tears flowed down.

How many women like them have not had such a bitter background?

"Don't cry, the wicked have their own harvest! The official family has already avenged you, don't cry. Everything will be fine. Master Li coaxed Cui Kui'er.

"Aoi Er knows. Aoi Er knows. Cui Kuier still cried non-stop.

When Fan Ruwei captured Huainan, the Cui family in Huainan was surrounded, relying on the fierce resistance of the soil fort, Fan Ruwei killed countless family children, so he left a few long houses and sent them to Bianjing.

And there is also ironclad evidence that the Cui family collaborated with the enemy and betrayed the country and colluded with the Jin people.

It's no wonder that Zhao Huan can spare them.

Cui Kui'er's case didn't even have a criminal record, and she was also expelled from the lintel, so she naturally escaped the royal order of beheading.

"Everything will be fine!" Cui Kui'er nodded vigorously and said.
