Jia Cong priced two taels of a box of arsenic vanamin, which contained enough doses for several injections, which was enough to cure patients in the early and mid-stage range.

It is packed in a small glass bottle, plus a glass syringe, so the price is slightly higher, and it is reduced to one or two or five dollars during the promotion period.

The purchasing power of the currency of the world of Red Mansions, Xue Baochai said when governing the Grand View Garden, that is, "Min Tan Chun Xing Xing Li removes the disadvantages of the night, and knows Baochai Xiaohui in general" This time, eight hundred taels of silver can see a few rented houses and add a few acres of thin land.

Even if we use the highest conversion of 600 yuan for one tael of silver, then the maximum of a few acres of land and a few houses in the capital is only 480,000 yuan, and in this embryonic period of feudal capital, it is normal for handicraft producers and laborers to have an annual salary of five to eight taels of silver.

Therefore, it is absolutely affordable for patients in the early and intermediate stages.

Jia Cong, who can't afford it, won't be a good person for free, because they have invested a lot of manpower, material and financial resources, and there is no patent protection in this era, he can protect the formula for a while, but it is not certain that it can be protected permanently, which is unrealistic.

Moreover, Jia Cong also gave up the profiteering practice of only selling to the middle class and above, taking into account the interests of more low-level people, in fact, this is also what he wants to maximize the profits, although only selling to the middle class makes money quickly, but the customers are too thin, the target group is small, and the final benefit will not be too big.

It is a tacit matter for the powerful to secretly do big business, in history, Wang Shizhen's privately operated money village has a huge profit of 300,000 taels every year, and so on, and so on, when the people of the faction of Prince Zhongshun have done this for a long time, Jia Cong is not afraid of this at all, everyone is not clean, and if they want to pull it out, they will finish playing together.

The second more important thing is research, the ancient bookstore wrote gods and demons, the market, are called to hire writers to go to the market to investigate the preferences of customers, and then study, other operations are similar, modern research is an indispensable part, it plays an important role in the correct decision-making, the prevention of future risks, how much to buy and how much to sell, and so on.

Queen Qianxiang gave him the feeling that she was also a good partner in business, and she also knew a lot about those clean products, and Jia Cong immediately called Zheng Yeliao and Luo Gaocai of Shanhai Bookstore to take a look at the market research report they asked someone to collect.

Generally speaking, the ancient clean products are pig pancreas and honey locusts are indispensable, and other materials have different formulas, Jia Cong's list comparison, no matter what, his soap is the most affordable, it can do more than most of the same kind, and will not eat away all the same kind, because the good supplies in ancient times also have their advantages; Secondly, Jia Cong's soap must be continuously improved to adapt to a wider market, remove fishy smells, hurt hands, etc., which undoubtedly increases production costs and improves production technology.

But it's worth doing.

After Jia Cong was busy with this, he was ready to go to Xue Zhen and Xue Baoqin to see the situation.

……

The two princes of Ning Guo and Rong Guo on the ancestors of the Jia family are two of the eight dukes, and the mansions of the other four kings and six dukes are quite far from the second mansion of Ning Rong, and the exchanges are not very close, separated by several streets and alleys.

Although most of these princes and aristocratic families did not participate in supporting Jia Cong's medicine workshop, the people led by Niu Jizong, the grandson of Zhenguo Niu Qing and the first-class earl, were still secretly investigating the sales of Jia Cong's arsenic vanamin.

Because Niu Jizong and the others are still the Han generals in the Jinyi Guard, they are quite close to Zhao Kang's faction, and Zhao Kang ordered them to be the master of ceremonies.

When he came back from work on this day, Niu Jizong walked into the courtyard of the Zhenguo Mansion, and together with several brothers from the family, they were all dressed in red python clothes, flying fish suits, black gauze hats, and belts, which were majestic.

Niu Jizong, Liu Fang, Chen Ruiwen, Ma Shang, and Hou Xiaokang are all tall and slender, all because of their extraordinary family background and resources, they are all majestic and majestic in terms of face and figure, not to mention that Chen Ruiwen and Ma Shang are like Jia Zhen of Ningguo Mansion who was killed by Jia Cong, one is General Sanpin Weizhen, and the other is General Sanpin Weiyuan, all of whom are the patriarchs of the family, and Jia Zhen was General Sanpin Weilie before his death. Niu Jizong, Liu Fang, and Hou Xiaokang all have titles, the former is a first-class uncle, and the latter two are first-class sons.

However, the two knew that their titles were coming to an end, because like the second duke of Ning Rong, the dukes in the eighth duke's family were all dead, and the children and grandchildren were just waiting for the decreasing lords, and sooner or later they would become commoners, and even if they were liquidated, they would not even be as good as civilians.

Therefore, there are people in every family who are anxious to find a way.

"Shi Guangzhu is now without power and position, and the Duke of Xuguo is about to exist in name only, my subordinates have reported that Shi Guangzhu's cronies have to operate in Nancheng, and it is roughly estimated that the profit from the promotion and sale of their Nancheng family should be four or five thousand taels in a month." Liu Fang waved her belt, stood up and picked up the tea and drank it, panting, unwilling and envious.

Four or five thousand taels a month is indeed a lot, according to this, it should not be difficult for Shi Guangzhu to invest back and make a profit, that kind of medicine has been generally confirmed, although some side effects are better than the original medicine, too the hospital can not refute it.

Chen Ruiwen's eyes were cold: "This matter has made Zhao Gonggong, who is in charge of the palm seal, dissatisfied, saying that for some reason, the emperor has also lost his bad attitude towards Jia and Xue, which undoubtedly makes Jia Cong like a tiger, Zhao Gonggong is just in power, Jinyiwei is under his control, and we have to stand in line." Wouldn't it be okay for us to secretly buy in batches to change hands? And the people of the Three Princes' faction won't look at Jia Cong and they lie down to make money, right? ”

Niu Jizong said gloomily and resentfully: "Damn it! It seems that my people are restricted from buying in batches, and unless they are involved in financing, they are never allowed to buy more than 50 boxes at a time. ”

Hou Xiaokang pondered and sighed: "Oh no, Dingcheng Houfu Xie Whale is a guerrilla in the Beijing camp, and Qiu Liang of Jingtian Houfu is a general of the Five Cities Soldiers and Horses, they must have manpower in the city to fight back against us." ”

Everyone secretly hated it.

Time and time again, it seems that Jia Cong is about to be in danger.

He just has the means to turn defeat into victory, he will curry favor with the emperor, he will win over the camp, he will be an official, he will be able to write Bagu Wen, he will go to the sea to fight, and he will invent and create, is this still something that people can do?

is also a child of the Xungui family, and they are still sisters-in-law, but Jia Cong is a concubine, and he has to learn to protect himself since he was a child.

Thinking about it like this, they couldn't help but feel ashamed, and Niu Jizong finally said: "But a few people from the Hou Mansion, we are still the Princess, what are you afraid of them?" By the way, I have a trick, those foreign devils know the formula, I don't think they may be willing to be imprisoned by Jia Cong for a lifetime, let's find a way to get them out. ”

"It works." The three of them were overjoyed, and their eyes were full of brilliance, once this task was completed for Zhao Gonggong, they would naturally follow the rising tide, and the real power would increase, and the revitalization of their respective families would be expected.

Liu Fang also said: "My people also found out that Jia Cong's private soap is also expanding the workshop, this thing has long been sold to the Yangzhou branch, I have used it, it is not as good as the best clean recipe, but it is cheaper, better than soap, the market is very broad, and it is better to steal it out." ”

"Damn, why did he take all the good things!" Chen Ruiwen became more and more jealous, everyone was red, and they all agreed to get Jia Cong's formula, everyone made money together, and Jia Cong was not allowed to eat alone, they discussed it with confidence, and they didn't feel that it was stealing or robbing at all.

The emperor's trust in Zhao Kang is much higher than that of Jia Cong, after all, Zhao Kang is a slave who has accompanied the royal family since childhood, and this intimate trust in Jia Cong is far from comparable, so they don't feel that they are afraid of Jia Cong.
