With something on his mind, Zhou Jun got up not long after lying down.
The sky outside was misty and bright, and when I looked up, I could vaguely see the moon and stars in the horizon.
Zhou Jun dressed neatly, walked through the corridor, walked into the study, spread out the rice paper, poured water to grind the ink, took out a chicken pen from the pen holder, dipped it in ink, and used the posture of holding the pen in his previous life to tilt it on the paper.
I scribbled down a line: A plan to make money.
Zhou Dinghai's lawsuit made Nu Yalang's job more and more difficult. Zhou Jun wanted to try to see if he could find another way out.
While reminiscing about his past life, he tried to write down the money-making techniques he knew.
First, Zhou Jun wrote the word glass on the paper.
After hesitating for a long time, Zhou Jun wrote three words uncertainly - "Burning Sand".
How to burn sand?
What chemicals should be added when burning?
When will it be added?
At what temperature is the temperature controlled?
Zhou Jun was a little confused when he looked at the series of questions he had written.
After thinking again and again, he crossed out the word "glass" with a pen.
Then, Zhou Jun wrote the word "mirror".
Mirrors polished with copper and silver were already common in the Tang Dynasty, but it seems that mirrors coated with mercury did not appear until the 14th century?
Zhou Jun tried hard to recall the manufacturing process of mercury mirrors, and soon he discovered that glass also seemed to be used in that thing.
There was no way, the mirror was deleted again.
Later, Zhou Jun wrote about movable type printing.
The movable type seal used in movable type printing seems to use a variety of materials such as lead, copper, zircon, rosin, wax and paper ash. The ink used seems to be particular, and it seems unrealistic to make money from this thing.
Zhou Jun had no choice but to delete the movable type printing again.
After a long time, Zhou Jun looked at the dozen or so deleted and altered technologies from his previous life on the paper, but none of them could be realized. Zhou Jun wanted to cry without tears.
Most of the novels and TV shows that Zhou Jun watched in his previous life emphasized that the Tang Dynasty was backward and had no technology, and that you could get rich by just tinkering with things.
It was only in the Tang Dynasty that Zhou Jun discovered that the truth was not the case at all.
For example, distilled liquor (shochu), many people conclude that distilled liquor (shochu) is based on the sentence "Shochu is not an ancient method, and its method has been created since the Yuan Dynasty..." in Li Shizhen's "Compendium of Materia Medica·Gusi·Shochu"
It only appeared in the Yuan Dynasty.
But in fact, in the literature of the Tang Dynasty, shochu and steamed wine had already appeared.
Li Zhao's "National History Supplement" says: "Wine is like Shaochun in Jiannan" (wine is generally called "Chun" in the southern region of the Tang Dynasty); "Qu Ben Cao" written by Tian Xi says: "Siam wine is known as "Chun".
The shochu is burned twice to add precious and exotic aroma."
If we really want to trace the origin of distilled liquor, then it is possible that the distillation and cooling method of making liquor had already been invented during the Eastern Han Dynasty.
In his previous life, Zhou Jun once visited the Shanghai Museum, where there was an exhibit called a bronze wine steamer from the Eastern Han Dynasty.
After identification by bronze experts, it was a product from the early or mid-Eastern Han Dynasty.
The exhibition hall also used this distiller to conduct distillation experiments, and distilled liquor with an alcohol content of 26.6-30.4.
Another example is salt production. During the Tianbao period of the Tang Dynasty, the basic salt production method of "cultivating the border and pouring it in the sun" was also commonly known as the "five-step salt production method", that is: collecting brine to evaporate, passing it through a basket to remove impurities,
These are the five steps of storing brine, crystallizing and scooping out.
Salt in Chang'an City costs ten yuan per dou, which is slightly more expensive than rice, but ordinary people can afford it, so there is no saying that they cannot eat salt.
There are also those stirrups. Many books say that there is no such thing in the Tang Dynasty. As long as this thing is built to enhance the combat effectiveness of the cavalry in the Tang Dynasty, the saint will be so happy that he can be granted the title of Marquis and Prime Minister.
Unfortunately, stirrups already existed in the Eastern Han Dynasty. By the Tang Dynasty, cavalry were even equipped with black technologies such as combination armor, buckles, and saddles.
There are also other things such as mahjong, hot pot, tofu, hot air balloons, etc., which were all available in the Tang Dynasty.
As for the other "advanced technological products", Zhou Jun was just a police officer who graduated from the police academy in his previous life. Apart from his usual love of reading history books, he had never been exposed to these messy technologies.
Zhou Jun is really doubting now, what are the brains of the protagonists who traveled through ancient times in the past life novels?
Why can you remember so much miscellaneous knowledge?
How dare these people carry encyclopedias with them when they travel through time?
This is totally unrealistic!
Zhou Jun crumpled the rice paper on the table into a ball, threw it against the wall, and yelled a national curse angrily.
Looking up, Zhou Jun realized that it was already bright outside the window.
With a depressed look on his face, he walked out of the study, took a deep breath, then braced himself, and walked towards his parents' wing.
Walking to the door of the wing, Zhou Jun saw Luo Sanniang commanding a group of servants and maids, washing and dressing Zhou Dinghai who had just woken up.
Zhou Dinghai was sitting on the edge of the bed, wearing a pair of underwear. His face was pale because of the hangover, and he looked depressed.
He took the moxa tea brought by the servant, rinsed his mouth, and then weakly asked Luo Sanniang: "What happened last night?"
Luo Sanniang said angrily: "You still have the nerve to ask questions. You drank so much wine and yelled. It must be a joke to the neighbors."
Zhou Dinghai rubbed his forehead and waved his hands helplessly, indicating that he really didn't remember.
Zhou Jun came forward, greeted his parents, and then stood aside.
Seeing Zhou Dinghai's dejected look, Luo Sanniang couldn't bear it. She sat next to him and asked, "Would you like to eat some soup cakes to warm your face?"
Zhou Dinghai shook his head.
Luo Sanniang raised her head, looked around, and said, "Let the others go out first, Jun'er, you stay."
In the blink of an eye, only three members of the Zhou family were left in the wing.
Luo Sanniang asked Zhou Dinghai softly: "But those officials in the city department are giving you a hard time?"
Zhou Dinghai said: "As a woman, you don't care about this..."
Luo Sanniang interrupted him in a deep voice: "I have followed you since I was sixteen, in Saibei, Longyou, and Guanzhong. In every difficult situation, we, husband and wife, did not walk hand in hand and endured it together? Even if the sky fell.
Come down, you can't bear it alone."

Then, he looked at Zhou Jun and said, "Jun'er happens to be here too, so let's talk about what's on our minds as a family."
"Although the county government finally acquitted me of the previous case of selling a good man, as a slave, I can't get away with the city department's record of selling a good man." Zhou Dinghai mentioned this matter and said.
There is endless regret in it: "The city department has the responsibility for Nu Yalang to take the school entrance examination. Those who commit minor offenses will be punished, and those who commit major offenses will be punished."
"It seems that the mistake I made this time will be recorded in the Municipal Department's files, and there will be no possibility of overturning the case."
Zhou Dinghai sighed again: "Originally, I thought it would be easy. If I were on the wrongdoing list, I would just give him a guarantee and let Jun'er take the position of my slave tooth master. Our Zhou family's business will go on as usual."
"But I missed a step after all. The case that put me on a bad book is a small matter, but offending the city officials and colleagues is a big deal."
Zhou Jun and Luo Sanniang looked at each other and realized that this was indeed the case, and Zhou Dinghai was only a belated observer.
Luo Sanniang comforted Zhou Dinghai and said: "Even if the city officials and colleagues don't like it, you have been a slave for many years and have accumulated many regular customers. If they help introduce some slaves, you can still do it."
Zhou Dinghai shook his head and said: "There are indeed regular customers, but it doesn't help."
Luo Sanniang asked curiously: "It won't help the matter?"
Zhou Dinghai: "Even if they are introduced by regular customers, if the buyer knows that my Zhou family has been involved in the case of "short selling of a loved one", most of them will change their dentist in order to avoid trouble."
Luo Sanniang: "If we don't tell the buyer, won't it just end?"
Zhou Dinghai closed his eyes and said: "Zhijian, the city bureau, and the city will all be involved in the slave transaction, and the buyer will know about the case sooner or later."
Zhou Jun said: "In my father's opinion, if we clarify the details of the case in advance and gain the buyer's understanding, is it possible for the slave order to be completed?"
Zhou Dinghai: "Difficult! If I were the buyer, there are thousands of slaves in Chang'an City, why would I choose your Zhou family? Although my case of selling a beloved man for a short while was an unjust case, it is there in the book, and it is irrefutable.
.”
Zhou Jun scratched his head. What Zhou Dinghai said was indeed true. Buyers would not choose Nu Yalang who had a criminal record.
When Zhou Dinghai said this, he paused for a moment and then said: "Unless...the buyer can only choose the Zhou family to buy the slave mark..."
Zhou Jun was stunned and asked Zhou Dinghai: "Can you only choose the Zhou family?"
Zhou Dinghai nodded and said: "The origins of slave orders are: one is the city office, the other is the city hall, and the third is regular customers..."
Zhou Jun nodded while listening, he knew all this.
Zhou Dinghai: "...the fourth is Shen Dan."
Um?
Is there a fourth source of Nudan?
Zhou Jun's eyes widened and he asked: "What is Shen Dan?"
Zhou Dinghai: "The so-called slave teeth and sinking orders, as the name suggests, are the slave orders that no one could do in the past. They are sinking there and no one can touch them."
Zhou Jun: "Why doesn't anyone touch it?"
Zhou Dinghai: "There are many reasons. For example, the buyer is too stingy and the bid is too low; or the buyer has a bad attitude and is extremely difficult to serve; and the buyer's requirements are too high and cannot be met at all."
"Although some slaves tried to do these things, they always came back without success. They accumulated there, and over time, no one dared to touch them, so they were called sunken things."
Zhou Jun became more energetic: "Father, where can I find these Shen Dan?"
Zhou Dinghai: "There are many in the lockers in my study, but..."
Before Zhou Dinghai could finish speaking, Zhou Jun said goodbye to his parents, turned around and walked towards the study.
Watching Zhou Jun leave, Zhou Dinghai was stunned for a moment, and then sighed: "There is no one to do it for Shen Dan. Of course there are reasons for it. I'm afraid Jun'er will suffer a lot."
