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

Although the money didn't seem like much, it was the first time selling vegetables, and many villagers were still observing, so the amount of vegetables collected was not much.

Secondly, even a strong laborer could earn about the same amount of money working in town for a day, and they only spent a morning doing so, so it's already pretty good.

Sure enough, on their second trip to sell vegetables, they bought more than 70 eggs and over 80 jin of vegetables. Liu Nanjia started calculating on the way, and after deducting some losses, they estimated they could earn about 40 wen that day.

As she predicted, six eggs broke this time.

The straw wasn't very effective at securing the eggs; they kept wobbling around in the basket and ended up bumping into each other.

So, after selling her vegetables today, Liu Nanjia didn't rush to leave. Instead, she found a carpenter's shop in town and prepared to have something made.

When they arrived at the shop, they were greeted by a young boy. After hearing that they were not buying anything but ordering something custom-made, the boy led them into the shop to find the carpenter.

Liu Nanjia described what he wanted to make. Actually, it wasn't anything special; it was just an egg tray, much like the racks in refrigerators in later generations specifically for storing eggs.

Drill several holes in a wooden board that are slightly smaller than the diameter of an egg. When drilling the holes, bend the cut edge slightly so that the egg can be held in place and not fall down. There is a groove at each of the four corners.

Four more legs are attached to the bottom of the board, fitting perfectly into the grooves of the next layer to prevent them from wobbling. The height of the legs is determined by the height of the eggs, ensuring that the eggs won't touch the board when stacked layer by layer, but without leaving too many gaps either.

This design was devised by Liu Nanjia using her limited brainpower. Although it is still not as good as the egg trays of later generations, it would be too difficult for her to describe the shape, and the production difficulty would be much higher.

Let's start with a simplified version.

However, what seemed like a rather simple design to Liu Nanjia actually piqued the interest of the carpenter.

Fearing she might not be able to explain herself clearly, Liu Nanjia found a piece of paper and roughly drew a picture.

The carpenter's surname is Fang, and he is actually the owner of this shop. The boy just now was his son.

Liu Nanjia took out the blueprints, and both father and son gathered around to study them, marveling at her good idea, saying it was quite interesting.

The egg tray is actually a small item, and they won't make much money from it, but because of the novel idea, they agreed to make it for them, and they can pick it up this afternoon.

Liu Nanjia thought for a moment, then asked the carpenter for a charcoal pencil and started drawing on the paper.

This time, she drew a crutch under the armpit, which was prepared for Song Chen. His foot injury would take more than 20 days to heal, and during this time, he could not put weight on his injured foot, so he would have to stay in bed.

At this moment, Liu Nanjia felt sorry for him, wondering if he had a cell phone to pass the time. So she thought of this thing and decided to do it out of kindness!

Armpit crutches aren't difficult to make with blueprints, and carpenter Fang readily agreed. However, his gaze towards Liu Nanjia became even more eager: "You may look young, but you have plenty of ideas. If you ever have anything new or interesting, come to me again, and I'll make sure to make it for you."

"No problem, as long as your work is good, I'll definitely come back to you." Liu Nanjia smiled and said, she was worried that people wouldn't like these little things and wouldn't be willing to put in the effort to make them.

She didn't leave immediately. After the carpenter finished making an egg tray, he showed it to her and, very satisfied, ordered four more.

One layer of egg tray can hold 20 eggs, so 5 layers can hold 100 eggs, which is enough for them for now.

Then they stopped waiting there and went to the bookstore, planning to come back later to get it.

Liu Yanxi hasn't started teaching yet, so he's been relatively free these past few days. He's finished copying the two books that Manager Wu from the bookstore gave him last time, and he'll hand them in today and take some more back with him.

Shopkeeper Wu looked at the books he had copied and was very satisfied: "Not bad, I knew I hadn't misjudged you. Take a few more back today, no need to rush, take your time copying them."

As she spoke, she settled the wages for the two books with him, which amounted to more than 50 coins.

Since there was still time, Liu Nanjia led her younger sister to continue exploring the town, where they bought some rice, flour, and meat.

The reason is simple: having gotten used to refined grains, even Liu Yanxi, who doesn't care much about food, doesn't really want to eat coarse grains anymore, let alone Liu Nanjia. Before, when she ate coarse grains, she had to force herself to swallow them.

As for the meat, Liu Nanjia said that they were still growing and needed nutrition. How could they grow taller without protein?

Although Liu Yanxi didn't understand what his sister meant by protein, he was indeed provoked by Song Chen and was afraid that he would stop growing, so he agreed to buy meat.

Needless to say, Liu Sirou was also quite happy. Although she was a bit precocious, she was only 5 years old after all. She knew that buying meat meant good food, so of course she was happy.

After they had walked around and picked up the finished products from the carpenter's shop, Song Chen had been waiting for quite some time when they returned to the clinic. Although he wasn't impatient, he was indeed curious about what they had been doing and why it had taken so long.

Liu Nanjia gave a brief explanation, then pointed to the crutch and said, "Here, I had this custom-made for you. Try it on."

Then I explained how to use this thing.

Dr. Bai happened to have some free time at the moment, and watched with great interest, urging Song Chen to try it quickly.

Song Chen was somewhat surprised. Was this made especially for him? Heaven knows how bored he was lying in bed, and how easily he would overthink, remembering his parents and those unpleasant things.

But he was staying at someone else's house, and the Liu siblings had already taken good care of him, so he didn't want to trouble them any further.

Song Chen obediently took the crutches and used them to stand up. His other leg was fine, and following Liu Nanjia's instructions, he took a few steps with the crutches.

Well, to be precise, I should say I hopped a few steps.

"How does it feel? It's too tiring and dangerous for you to hop on one leg all the time. That's when I thought of this thing. It should be better than those canes, right?"

Liu Nanjia couldn't wait to know how he felt; this was probably the first piece of modern technology she had brought with her.

Song Chen nodded. "With this supporting me, it saves a lot of effort. Thank you."

Although his expression didn't change much while he spoke, the pursed corners of his lips revealed that he was not at peace.

Liu Nanjia waved her hand again: "No need to thank me. With this, you can walk a few steps on your own, and it will be convenient for you to go wherever you want. My brother won't have to keep supporting you. It's a win-win situation."

After saying that, he was a little embarrassed, "Actually, it's best to use two of these together, one on each side, so you can exert more force. We don't have much money right now, so we only made one for you. But there are only about 20 days left, so you can make do with it for now."

Song Chen shook his head: "I'm already very grateful that you made this for me."

Dr. Bai interrupted their pleasantries, picked up the armpit crutches and examined them closely. He even pulled Song Chen to walk a few more steps, clearly very interested in the thing.
