The few pedestrians on the street stopped one after another, and then they were attracted to come, and the tradition of Han onlookers helped them a lot at this time.

After a while, there were already seven or eight men and women, circling around them, asking what they wanted, and one of the eldest ladies said, "Say soap all over the place, do you dare to stain your clothes with mud and wash them with soap?" ”

"Why don't you dare?" The man seemed to be enraged, he took out a piece of gray gauze from his pocket, raised it to the crowd in front of him, and then put it on the ground with residual snow, and stepped on it with his foot, "Look at it! ”

Everyone was laughing, although the snow on the ground had not melted, but when they stepped on the mud with their feet, the gauze was still stained with a lot of mud, especially when they stepped on it, leaving a lot of mud marks.

The man rubbed it with his hand to let the soil fully burrow into the cracks of the cloth, and then gestured to everyone, then threw it at the basin, and said to the man who was close to the basin: "The effect of this soap depends on you now!" ”

"Okay!" The man near the basin agreed, and then took out a paper bag from his arms, peeled off the kraft paper on the outside, and revealed a pale yellow "square brick" inside, the size of a fist, "Everyone, look at it, this is what we call soap!" ”

He first moistened the gauze with water, then rubbed the soap on the gauze, put down the soap, and rubbed it vigorously.

Countless foams suddenly appeared on the gauze, much faster than the soaphorn leaves, and the foam was thicker.

The onlookers were amazed, and the lady, who didn't believe it very much, leaned her head over to see what was going on.

"Don't worry, it'll be fine in a while!" The man rubbed it for a while, and then put the gauze into the clear water, and after another rubbing, the water immediately turned muddy gray, and there was a thick layer of water foam on the surface.

He wrung out the gauze and handed it to the impatient lady, "Look, is there still dirt on the gauze?" ”

The eldest lady took the gauze, looked at the front and back carefully, and unconsciously showed an embarrassed smile, "Hey, it's really clean," and glanced into the basin again, "It turns out that the soil really fell into the wooden basin, this soap...... It's really good......"

There were more and more onlookers, and some people deliberately joked: "It was floating soil just now, if it is dirt on the collar of the clothes, can it be cleaned?" ”

"Of course it can be cleaned, how can there be soap to wash floating soil?" The man glanced left and right, and happened to see a young woman, carrying a basket of cabbage, and I don't know if she had just bought it, or if she was going to sell it in the market, he deliberately looked away, not looking at the woman, "Don't say that the dirt on ordinary clothes, even a woman's dirty clothes and pants, can also be completely washed, I don't believe anyone to try it......"

Everyone knew that he was making fun of the woman, and suddenly there was a burst of laughter, and the woman blushed with shame, gave the man a blank look, and hurriedly left the crowd and disappeared from everyone's sight.

There are too many onlookers, blocking the entire Dongmen Street, pedestrians not to mention patronizing the shops, even the passage is extremely inconvenient, the second child of the opposite shop, then crowded over to protest, "I said you people are really, kind to lend you brooms, but I didn't expect you to have to inch in, actually block the road, and let people not do business?" ”

"Little second brother Hugh is going to be annoyed," the leading man squeezed over and threw his hand at Xiao Eryi, "I'm really sorry," and took out half a piece of soap from his arms and handed it over, "This half of soap should be used as an atonement, and after a while, everyone will disperse, and we will leave immediately!" ”

Xiao Er looked at the half of the yellow and greasy square in front of him and said, "This is what you call soap?" Can you really wash dirt off your clothes? ”

"Definitely, you might as well try, if you have half a lie, you will smash my sign," the leading man smiled, "Little second brother, you are the first person to get soap......"

Xiao Er got something soft, so he got off the donkey down the slope, "I'll try it!" "I went back with a cigarette.

Some people didn't plan to go to the morning market, but they listened to the words of their neighbors and came to see what was going on.

It's a pity that the few men at the square table have a principle: only give away, don't sell!

No matter how much money is paid, people just won't let go, if you wait in line, you can send a small piece.

For three days in a row, Dongmen Street was very lively, and there were uncles and aunts who were greedy and cheap and queued up to receive fat boys, and some families went into battle in order to get a piece of soap the size of a pipe.

In the whole city of Xining, the word "soap" spread all over the city, not only the big girls and little daughters-in-law, but also the old men in their sixties and seventies and seventies and seventies and eighties, all knew that there were new things in Xining City.

But almost all people don't know how soap came to Xining and who produces it.

On October 14, the last day of the soap exhibition on Dongmen Street, John Tong came to the Governor's Mansion.

John Tang asked to see Li Zicheng, naturally not for the sake of soap.

Li Zicheng knew it even better, he heard that Tang Ruowang was visiting, and immediately summoned him in the study of the Central Government.

Tang Ruowang first saluted, and then took out a stack of white sandpaper from his body, "Dadu Governor, this is the technology I have sorted out in the past few days, Dadu Governor will see if it can produce products." ”

Li Zicheng took the white sandpaper and put it on the square table in front of him casually, "Mr. Tang, I can't finish reading these technologies for a while, you can tell me first, what technologies are there!" ”

"Leather shoes, wine, woolen sweaters, cotton and linen carpets, self-striking bells," John Tang paused, and then said: "There may be some techniques, but I can't think of them for a while, and I can't perfect ......them in time."

Li Zicheng nodded, but he was thinking in his heart whether the products produced with these technologies would be marketable in Daming.

Leather shoes, woolen sweaters are good, Xining, Longyou belong to the north, the climate is relatively cold, just can be used, wine, chiming bells should belong to high-end luxury goods, the main market is still on the side of the imperial court, and this cotton and linen carpet, and only high-ranking officials and nobles have spare money to buy.

Li Zicheng originally hoped that in the future, the factory would produce goods mainly for local sales, but now it seems that he is still too anxious, and before the completion of the primitive capital accumulation, the local merchants in Xining will not be able to reduce the price in the form of mass production, and the local people will not have enough purchasing power.

The merchants, like the common people, were short of money.

Li Zicheng smiled bitterly: "These technologies, stay for the time being, I'll take the time to see if I can produce the product." ”

Of course, he will not set up his own factory to produce, and it is better to sell these technologies to businessmen in Xining.

Tang Ruowang saw that Li Zicheng was not very interested, and thought that Li Zicheng couldn't look down on these techniques he had sorted out, so he hesitated and said: "Metropolitan Governor, when I was in Xi'an, I heard that there was a strange person in the local area, named Wang Zheng, who had mastered a lot of strange skills. ”

"Wang Zheng?" Li Zicheng thought for a moment, but it had no effect, at the end of the Ming Dynasty, he knew a Xu Guangqi, "Who is this Wang Zheng?" How did Mr. Tong know about him? ”

"Wang Zheng is a native of Jingyang, Xi'an, a jinshi during the Apocalypse, and he is not very proud of being an official, but he has a lot of research in science," Tang Ruowang said: "He compiled the "Illustration of Strange Instruments in the Far West" in the seventh year of the Apocalypse, which is said to have not only translated the practical techniques of European missionaries, but also had many innovations himself, but unfortunately, I have never seen ......."

"Scientific achievements?" Li Zicheng unconsciously compared him with Xu Guangqi, "How is this person better than Xu Guangqi?" ”

"In the Ming court, Xiang has the title of 'King of Southern Xu and North', which should be as famous as Xu Guangqi."

"Same name?" Li Zi came to be interested when he was established, and the people who can be as famous as Xu Guangqi must not have a bad level of science and technology, and they also have their own scientific and technological works, no wonder he has not made progress in his career, but he has a faint worry, "Since Wang Zheng is an official of the imperial court, he should not come to Xining ......"

John Tang was in high spirits and said, "Governor, this person is also a child of God, and in order to learn science and technology, he has always been associated with missionaries, and he has long been baptized and preached. ”

"Baptism?" Li Zicheng was overjoyed, if Wang Zheng was baptized and enshrined, it could be seen that he was interested in science, and he was not only the pope of Catholicism, but also created many new things in Xining, I don't know if these can attract him, so he said: "Where is Wang Zheng now?" ”

"This ...... I really don't know that when I was in Xi'an that day, he was an official in a foreign country, and his affairs have been widely spread among the imperial court and missionaries," John Tang's blue eyes shook from side to side, "Unfortunately, I only saw him once in the weather year." ”

"Since he is from Jingyang County, Xi'an Prefecture, he should be able to find out his whereabouts," Li Zicheng said: "Is there any way Mr. Tang can let Wang Zheng come to Xining?" ”

Tang Ruowang pondered for a moment and said: "Although Wang Zheng has translated a lot of works and has a lot of originality, his scientific achievements have not been able to impress the world," paused, and said: "Shilin of the Ming Dynasty has always dismissed science as 'strange skills', and Wang Zheng has no ambi......tion in his career."

"I see!" Li Zicheng thought about it for a while, and already had an idea in his heart.

The practical technology that Tang Ruowang brought this time was what Li Zicheng expected, but the Wang Zheng he recommended to Li Zicheng was an unexpected gain.

If Wang Zheng can be found and he is willing to come to Xining, it will be a win-win situation.

For Wang Zheng, most of his life's work can be seen in the world during his lifetime, and it is not in vain, perhaps establishing his position in the history of Chinese science;

For Li Zicheng, the arrival of Wang Zheng can bring a number of advanced technologies, which are the technologies of this era and can be easily transformed into industrial products.

More importantly, Wang Zheng is still a Jinshi, and once he joins the Mandate of Heaven Governor's Mansion, the symbolic meaning is even greater.

Unlike Mei Zhihuan, who was defeated and captured, and involuntarily joined the Mandate of Heaven Governor's Mansion, Li Zicheng would not kidnap Wang Zheng, and whether he would come to Xining or not depends entirely on the attraction of Xining.

After sending Tang Ruowang away, Li Zicheng immediately flew a pigeon to send a message to Wang Anping in Shaanxi, asking him to find Wang Zheng's whereabouts.
