I traveled back to ancient times, but I was able to lie down and relax.

After selling all the vegetables, Liu Nanjia happily went to find Carpenter Fang to ask him to make a few more egg racks.

If all goes well, we might even be able to negotiate a collaboration!

Upon arriving at the carpenter's shop, they discovered Mr. Fang's son. Young Mr. Fang was overjoyed to see them and called out, "Dad, Miss Liu and the others are here!"

Liu Nanjia and Liu Yanxi exchanged a glance, both somewhat puzzled. Did they see them so happy?

Just then, Carpenter Fang hurriedly came out from inside: "Miss Liu, you've arrived! Come, come, please come in. I thought you would come to town today, and I was planning to go to the market to find you."

We chatted about them selling vegetables at the market last time we were waiting here.

Liu Nanjia was even more puzzled, but since she really needed to find Carpenter Fang, she led her brother and sister inside.

Carpenter Fang was even more enthusiastic than last time: "Miss Liu, tell me about your business first. What new and interesting ideas have you come up with this time?"

Liu Nanjia scratched his head: "No this time, it's still the same egg rack. When I was selling vegetables today, someone saw it and bought a few, so I came to ask you to make some more."

“No problem, that’s easy to arrange,” Carpenter Fang readily agreed.

Liu Nanjia thought for a moment and decided to make 10 this time; there was no need to make too many.

Then I thought I should ask the carpenter what he wanted before discussing their collaboration.

"Master Fang, you just said you were coming to see us, is there something you need?"

The carpenter, Fang, seemed a little embarrassed. "Hey, you guys made a crutches for me last time, right? Someone probably saw it and found out about me from Doctor Bai, and they want to buy one too. I just wanted to ask you, can I sell that thing to someone else? How about this, I'll pay for it and buy the blueprints from you, okay?"

Liu Nanjia was somewhat surprised. Did people in ancient times have such a strong sense of copyright?

In modern times, when something appears, there are often imitations or even pirated versions, and there are countless cases of plagiarism.

Surprisingly, here, someone actually bought such a simple design drawing.

Come to think of it, people at that time valued inheritance more. Any special recipes or techniques were usually passed down from generation to generation and would not be easily revealed to outsiders.

However, this is also because Fang the carpenter is a good person. If it were someone else, they might not necessarily ask for her permission and might have just sold it directly.

In that case, the collaboration she was thinking of should be achievable.

“Oh, so that’s what it is. That’s easy to discuss. You can sell the armpit crutches, but you don’t need to buy the blueprints. We can cooperate in another way. That’s why I came here today to talk to you.”

When Fang the carpenter heard that he could sell it, he was naturally happy. He was also very curious about what Liu Nanjia would talk to him about, so he gestured for Liu Nanjia to continue.

"Today, while we were selling vegetables, we noticed that quite a few people were interested in these egg racks, and some even bought them on the spot. I thought, since we were able to sell three today, is it possible that we can sell more in the future?"

“If there are always customers, then I will definitely keep hiring you for a long time. In that case, we can cooperate. I sell it for 20 coins today, and you can sell this egg rack for the same price. But since I designed it, you have to give me 5 coins for every one you sell.”

"It's like we split the profits. For each egg rack, you get 15 coins, the same price as the eggs you sell them to me, so you don't lose money, while I get 5 coins. Even if I contribute the design fee, I can still be responsible for promoting the eggs when I sell them."

After thinking for a moment, Fang the carpenter realized that he would sell egg racks at both Liu Nanjia's and his own stall, earning 15 coins for each rack and 5 coins for each one.

"So, for that armpit crutches, you're saying we don't need to buy blueprints, and we'll just divide them using the same method?" Carpenter Fang's reaction was quite quick.

“That’s right!” Liu Nanjia nodded.

Carpenter Fang agreed to Liu Nanjia's suggestion without much consideration. To be honest, if he really had to pay for the blueprints for the armpit crutches, he didn't know how much to pay, or how many he could sell after buying the blueprints, or whether he could make back the money for the blueprints. This way, he would take on less risk.

"Sure, but I have one condition."

Liu Nanjia suddenly felt that Fang the carpenter's smile seemed a little... a little cunning?

But since the cooperation was about to be finalized, she had to listen to whatever the conditions were.

"You say."

Carpenter Fang cleared his throat: "My condition is that if Miss Liu has any ideas or new drawings in the future, she should come to me for them, and she should give me priority consideration for new collaborations."

Liu Nanjia breathed a sigh of relief. She thought there would be some conditions. As for the armpit crutches, the fact that Fang the carpenter took the initiative to ask for her consent before selling them showed that he was a trustworthy person, so there was no problem with long-term cooperation.

But with just two little things, how can he be so confident that he can come up with even more ideas?

"No problem," Liu Nanjia readily agreed.

Then, in a serious manner, she asked both parties to draw up a written agreement, writing down all the agreed-upon matters, and then pushed Liu Yanxi forward to write it.

Carpenter Fang was somewhat surprised. How could a little girl from the village know about writing down an agreement?

Seeing Liu Yanxi's handwriting made me even more surprised.

However, they accepted it when they learned that their father was a scholar. No wonder they were so resourceful; they were the children of a scholar.

Well, in this era, and in a relatively remote place like Anping Town, a scholar was already considered a very learned person.

Liu Nanjia was happy to pin the blame on her deceased father, otherwise she really wouldn't know where these novel things came from.

Finally, both parties agreed on a price of 20 coins per egg rack, with Liu Nanjia and his group receiving 5 coins, since they had already sold them at this price and it was not appropriate to change it.

The profits from future collaborations will be split 20/80, as this involves materials, and different types of wood will have different prices, so a profit-sharing arrangement is more appropriate.

Then, Liu Nanjia came up with another idea. He took Fang the carpenter to the clinic and left his son, Master Fang, to make the egg racks they were going to take away that day, and also to watch the shop.

The purpose of going to the clinic is to discuss a collaboration with Dr. Bai. After all, only injured people need to use armpit crutches.

Of course, the clinics have the most injured people. If Dr. Bai introduces the benefits and uses of armpit crutches to those people, some patients should be willing to buy them.

Dr. Bai readily agreed, because not everyone with a leg injury can afford a wheelchair. Axillary crutches allow them to move around on their own, and the price isn't too expensive, which is a benefit to patients.

As they talked, Liu Nanjia came up with another idea: they could rent out armpit crutches to patients under the name of the clinic. For example, if someone sprains their ankle or breaks their bone, they can recover after a period of rest, so armpit crutches would be useless.

Renting with a deposit and receiving a partial refund upon return is more cost-effective than buying directly. If the crutches are not returned by the due date, the deposit is forfeited, essentially meaning the clinic has essentially bought the crutches, so they don't lose out.

This idea prompted Carpenter Fang and Doctor Bai to repeatedly praise Liu Nanjia for her cleverness, making her feel embarrassed. She thought to herself, "Ah, this is all the wisdom of our ancestors."

Hmm, for them, it should be the wisdom of later generations?
