The nobles rushed to buy Zhang Chao's soap, and they were very generous, and they would always ask for 100 or 50 yuan. However, these people were either men or marquis, and they did have money. They were either old and wealthy families or military scholars, and what they didn't lack was money.

No matter how expensive is soap, how expensive can it be?

Moreover, today there are all nobles here. Looking at Liu Hongji, Cheng Yaojin, the two guys, would have to pay a hundred yuan if they opened their mouths, and the others refused to lose face in this occasion.

Zhang Chao was very happy when he looked at these people's generous appearance.

The cost of soap is actually not high. There is not much soap. The trial model No. 1 that has been used up by the princes is only three taels, which is only about 125 grams. The main materials are lard, vegetable oil residue, and water, which account for a large proportion. Secondly, although the cost is not low, the amount is very small.

After all, Zhang Chao's soap eliminates the technical cost issue. The actual material cost is only about a hundred cents, which is really cheap. Of course, the material cost of 100 cents does not mean that Zhang Chao is planning to sell a article.

He knew that the prices of bath beans, fragrant medicines and facial fat sold in the medicine shop were very high and amazingly high. The things were like those cosmetics from later generations, and all kinds of extracts, beauty, etc. were very expensive. In short, those cosmetics from later generations were not small, only a few hundred or thousands.

The bath beans, fragrant medicines, and facial fats these days are the same. They are not products for ordinary people at all. They are specially supplied to wealthy families. Therefore, a bath bean made of more than a dozen medicinal materials does not even have half a liang, but can be sold for hundreds of cents. A piece of facial fat of about one liang, because of the precious materials such as pearls and jade shavings, they can be sold for a few cents per yuan.

In short, you can't afford to buy something that you think is expensive, and those who can afford it will not consider it expensive.

Even if you compare the price of fat on the market, you can buy a piece of soap of five jin per piece. Moreover, the reactions that everyone has so strongly after using it are, it is more popular than facial fat.

Zhang Chao decided to set the price higher, otherwise, he would be sorry for such a good product.

For these generous princes and marquis, Zhang Chao directly regarded them as his VIP guests, and he would be his own financial backers in the future. How could he make money by selling yellow buns?

"Dear Dukes, Dukes, Dukes, Marquis, Uncles, and officials, don't worry. Sanlang Soap is now accepting reservations from everyone, but the soap requires various rare materials and is not easy to make. Therefore, it is not easy to meet everyone's needs for the time being. You can register and book first."

Zhang Chao played hunger marketing once last time selling yellow buns, and the effect was very good. Therefore, he planned to do it again this time. The more rare it is, the more precious the soap is.

"Whoever booked, I will first provide two soap and five trial packs with different fragrances."

Adding different flavors to soap will have different fragrances. In fact, it is a very simple thing, but it can be sold as five products. It is really easy to make money.

If the conditions were not limited, there were too many ways to play with soap.

Refining caustic soda can be much easier than refining and processing surface alkali. However, the current restrictions on purchasing raw materials for alkalite have made Zhang Chao a little helpless. It is obviously a good project to make money, but it is impossible to start it with all its strength.

Zhang Chao learned how to make handmade soaps by himself from a computer, and it is not difficult to do it by himself, and it is difficult for others to learn it. The key to this soap is not all kinds of medicinal materials and spices, but hot alkali. This is purified from alkite stone. Nowadays, alkite stone is only used for medicinal purposes, or it is a Taoist priest alchemy, and there are few other uses to develop.

Moreover, there are several steps to refine the soda stone into caustic soda, and there is also caustication reaction with lime in the middle. People who have not learned chemistry will definitely not. It is estimated that only some alchemists may do it. Ge Hong's alchemy recipe in the Jin Dynasty has prescriptions for refining these things, but they are not very pure, and the refining process is more complicated and the cost is very high.

As long as Zhang Chao keeps the secret recipe for refining hot alkali, he believes that this soap transaction can always be exclusively monopolized.

Monopoly is the most profitable.

For a piece of soap, the alkali content only accounts for 40% of the alkali, the most is vegetable oil residue, accounting for 47%, nearly half, the second is clear water, accounting for 33%, and then lard, accounting for 4%, rosin accounts for 2%, and salt accounts for only 50,000.

Water is expensive, vegetable oil residue is very cheap, soybean oil costs only a hundred pounds, and oil residue is much cheaper. Lard is a little more expensive, and not much is available. Rosin, salt, and essence are more expensive, but the amount is not much used.

Only four percent of the alkali is the core, but the cost of a liter of alkali is only one thousand now. A piece of soap is only three taels, and using only five grams of alkali is only more than five grams. In fact, the alkali used for a piece of soap is only five or six cents.

If you can press the cost of essences and rosin, the cost of a piece of soap can be reduced a lot.

Refining one liter of alkali can process nearly two hundred pieces of soap. Although the supply of soda stone is insufficient now, it is still OK to extract a little to make soap.

After doing this, Zhang Chao thought this was really a good deal.

After Cheng Yaojin washed his face with soap, he kept touching his face and was not tired of touching it.

"Sanlang, I don't care about what you limit or not. I'm your uncle. If the family doesn't say two words, I don't care about others' purchases of one or two yuan. You have to give at least one hundred yuan."

"Uncle Shi, this is really difficult. You see, you are all my elder uncles. I can't favor one or the other." Zhang Chao said with a smile.

"Fifty, give it fifty first." Cheng Yaojin took a step back.

"This is a bit embarrassing. I'll give you fifty dollars, so it's not easy for the other uncles to satisfy you."

"Then let's get twenty yuan first."

"Uncle, do you think you can give ten yuan first? This means you are my uncle, otherwise you can't do it."

Cheng Yaojin rubbed his face and then called the butler, "Uncle Fu, what is the price of the fat we purchased in our family?"

"Let me, we bought it from Dejitang in the East City. Dejitang is the most famous pharmacy in Chang'an. The ones we bought are the best facial fat in their store. Their facial fat is one or two yuan per piece, and the purchase price is 1,500 yuan."

Cheng Yaojin nodded, one or two thousand five, and Zhang Chao's one piece was three or three.

"Sanlang, you also heard that Dejitang is one or two pieces, one piece is one thousand five. Uncle doesn't take advantage of you. I know that your soap is better, so it's six thousand one piece, how about it?"

This price is one-third more expensive than Dejitang's facial fat.

Six guans of soap is very good, not worse than Zhang Chao expected.

"I'll listen to my uncle."

"Then I agreed that I have to give my twenty dollars first."

Liu Hongji and others were unhappy. Why could Cheng Yaojin get twenty yuan, but they could only purchase two yuan? He is the Duke of the State, so I am not the Duke of the State? In terms of official positions, I am still the General of Zuo Xiaowei.

After being surrounded by a group of princes and marquis, Zhang Chao surrendered.

"Uncles and uncles, each company costs twenty yuan, no more, so you have to book in advance and wait for shipment."

As for the price, of course, it is as much as six cents of each yuan as Cheng Yaojin said.

In a corner of the living room, there was a group of officials standing there, and the people in the hall were a little out of place. These people were just coming from other halls. They were all civil officials, or officials from Shandong gentry.

Cui Shanfu is here. Although his official position is Ku Zhen, he is actually more of a staff member.

"That's the adopted son Zhang Chao and Zhang Wenyuan, whom Shubao's newly acquired?"

One person asked with a smile.

"Well, it's him, not a simple young man." Choi Sun-fu replied.

"It's better to meet than to be famous. When we meet today, it's really eye-opening. This man with more than 50 surnames nodded and smiled.

After a pause, he said again, "Are you really planning to marry Yingying to him?"

"Zhang Wenyuan is a good person." Cui Shanfu just replied simply.

"You are Yingying's father. Your father is the decision of your daughter's marriage. I, as an uncle, have nothing to interfere with."

This man in his fifties is the brother of Cui Shanfu's deceased wife, Zheng Shanguo of Xingyang Zheng family. Zheng Shanguo, where Zheng Shanguo is located, is the Zheng family of Xingyang, which has five surnames and seven sects, and the leader of the Shandong gentry.

Zheng Shanguo's father was the Duke of Kaifeng County during the Northern Zhou Dynasty. He died in battle when he was nine years old. Zheng Shanguo inherited his title at the age of nine, and was promoted to the Duke of Wude County at the age of twelve, and was appointed as the governor of Yizhou at the age of fourteen.

The Zheng family in Xingyang was quite prominent in the Northern Zhou and Sui Dynasty, especially in the early Sui Dynasty, when Zheng Shanguo's uncle was Zheng Yi, who helped Yang Jian usurp the throne successfully. With the relationship between his family and his uncle, Zheng Shanguo's official career was successful in the Sui Dynasty, especially when he later married the Cui family and married the Cui family.

At the end of the Sui Dynasty, he followed Yang Guang to visit Jiangdu. After being killed by Yu Wenji, he was appointed as the Minister of the Ministry of Civil Affairs. He followed Yu Wenji and went to Liaocheng. He was captured by Dou Jiande and was almost killed. Later, he was spared from death and surrendered to Chang'an.

Now he is the crown prince’s left sanctioned son and is granted the title of Duke of Xingyang County.

Zheng Shanguo had previously been an official in Li Shimin's Qin Palace, but he transferred to the Eastern Palace to be an official because the Crown Princess Zheng Guanyin was his niece, and Zheng Guanyin's grandfather Zheng Chen, Duke of Wushan County, Northern Qi, was his uncle.

The Choi-Jung family has also been married for generations. Zheng Shanguo's mother is Choi Shanfu's aunt, and Choi Shanfu's ex-wife is Zheng Shanguo's sister.

Although Cui Shanfu's ex-wife died early, the relationship between the two families is still quite close. However, Cui Yingying is a member of the Cui family after all, and Zheng Shanguo is not easy to interfere too much. This time he heard that Cui Shanfu was going to marry his niece to a poor family who was nothing, and he was very dissatisfied at the beginning.

But today, Zhang Sanlang, whom he saw in Cheng’s mansion, had a different feeling.

"A peasant child can talk to a group of nobles and princes in the hall of the Duke's Mansion, neither humble nor arrogant, and even take the initiative. This boy is indeed extraordinary. It is not surprising that you were cheated by him for 100 taels of gold last time."

When Cui Shanfu heard about it, he couldn't help but smile bitterly. That incident really made him feel angry for a few days, but now the yellow buns in Fumanlou are very popular, and Fumanlou uses the noodle alkali bought from Zhang Chao to take advantage of the opportunity to launch a lot of new noodles and noodles, which has won many new customers for Fumanlou, but it is not a loss.

"No wonder Qin Shubaoqing's eyes were added together and adopted son." Zheng Shanguo nodded and watched Zhang Chao happily make a deal with a group of princes from afar!
