Yun Wu raised her finger and poked Yun Dai's head gently: "What a black heart, just a small bag of things, a thin piece. It would be strange if you can sell them."

Yun Dai smiled and said, "My sister, you only look at the small things. Do you know how high the cost here is? We don't have latex trees here, and we all rely on merchant ships to get them from very far islands. I won't talk about the cost along the way. The production I came back is also time-consuming and labor-intensive. I chose young and clean women. I definitely can't treat them badly when I go out to work. The wages are a lot. I don't sell them expensively, so are I selling them to make fun of it?"

"Look, I just said something, she had so many words to block me." Yun Wu cursed, "Then I ask you, twenty taels of silver per box, can anyone buy it?"

"Of course." Yun Dai pressed his chin towards Hongdou, "Don't she just want to buy it? Do you think my time-consuming and laborious birth condom is to sell it to ordinary people?"

Ordinary people think that there are many children and many blessings. They will be born when they are pregnant, and generally they will not think of contraception.

Even if you really have too many births and can't afford to raise them, just use fish bladder and sheep intestines.

Yun Dai made this kind of thing for himself, and sold it with it to those who really need it.

One reason is that the yield is too low. Another reason is that it is still the era of manual work, and manpower is productivity. If ordinary people are contraceptive and not having children, who will farm, who will work, and who will join the army to fight in the future?

The court would not want to see this scene.

Therefore, Yun Dai did not intend to sell it to ordinary people.

The price of twenty taels of silver is no longer high.

As for whether the sales are good or not, she doesn't care.

Yun Wu asked Hongdou: "Are you really planning to buy it?"

Hongdou smiled with a red face, "Although I'm not very rich, I can still afford twenty taels of silver."

Yun Dai smiled wickedly: "Hongdou, are you willing to spend twenty taels of silver to buy a box every month?"

"ah?"

"What a fool." Yun Wu also smiled with her lips pursed.

Hongdou looked confused: "Why do you have to spend twenty taels of silver every month?"

"Because that thing is a one-time thing," Yun Dai smiled, "only use one at a time, throw it away after using it."

Hongdou suddenly realized and blushed.

She really didn't know, and she thought she could wash and use it...

Yundai laughed.

Hongdou's beautiful face was filled with red clouds: "The Empress likes to tease people and make fun of people."

"Okay, don't laugh." Yun Dai smiled for a long time, stopped slowly, and said seriously: "With Jin Lan's love for you, a box per month is probably not enough, right? Besides, Jin Lan is young and is in full swing."

Hongdou was so embarrassed that she couldn't do anything, so she simply turned cold: "I'll be annoyed if the empress makes fun of her."

Yun Wu said, "I'm sorry, Dai'er, you're almost the same, don't tease her anymore."

Yun Dai smiled and said, "These are all serious and practical things. How about making fun of it? Don't worry about money. As long as you need it, send someone to the shop to collect it. Can I still charge you? I will say hello to Gu Chengan."

"That won't work. You have to pay." Hongdou said, "Buy as much as you have. If you don't have enough, you can't help it. You have to ask him to go to the east yard."

Yun Dai said: "How much money do you have in a month now? Is it enough?"
