I trade in both worlds

"Yes, this is a learning machine. It contains all the courses from elementary school to high school." Xu Xu explained, "It is taught by professors from the best universities in the country. You can learn a lot of knowledge here in the future."

"Wow, thank you, sister." Xu Jin happily held the learning machine and asked, "Sister, how do I use this?"

Xu Xu smiled and opened the tutorial link provided by the seller, and demonstrated to the twins how to use the learning machine. She patiently taught them how to turn it on and off, how to enter the learning interface, how to choose courses, etc.

"Look, this is the learning interface. You can choose the corresponding courses according to your needs." Xu Xu said, pointing to the icons on the screen.

"Wow, there are so many courses here, including painting." Xu Zhun exclaimed, "Sister, can I learn painting?"

"Of course, you can take all the courses here." Xu Xu replied with a smile.

The twins and Xu Qiwei couldn't wait to start trying the learning machine.

Xu Tiantian also joined in the fun and crawled over to her uncles, staring at the learning machine curiously, and occasionally stretching out her little finger to press a few times.

Xu Qiwei looked at the learning machine with envy and said to Xu Xu, "Mom, I want a learning machine too."

Xu Xu squatted down and gently touched Xu Qiwei's head: "Weiwei, you are still young now. When you grow up a little bit, mother will buy you a learning machine, okay?"

"But I want it now." Xu Qiwei pursed his lips and looked at Xu Xu aggrievedly.

Xu Xu looked at him helplessly, thought for a moment and said, "You can buy it, but after buying a learning machine, you have to go to class after school, and you can't watch TV or play with the tablet anymore."

"Why?" Xu Qiwei looked at Xu Xu in disbelief.

"Aren't you going to buy a learning machine? Learning machines are used to attend classes and learn knowledge. Now that you have bought it, you must study with it." Xu Xu looked at him seriously.

Xu Qiwei looked at Xu Xu, then at the twins, thought for a moment and said, "Then let's not buy it for now. If I need it, I'll just use my uncle's."

Xu Xu was a little disappointed when she heard that he didn't want to buy it. She patted his head and said, "Okay."

After buying the learning machine, Xu Xu didn't pay too much attention to the twins' studies. Firstly, she herself didn't understand a lot of the knowledge, so she didn't want to cause trouble.

Second, the two children are quite self-disciplined. They get up in the morning and recite books for an hour before eating breakfast.

The first thing I do after school is to complete the homework assigned by the teacher, and then I will take a half-hour nap at noon.

I watch TV after finishing my homework in the evening, and start online classes after dinner. My time is well organized.

When Xu Ziqing saw this by chance, she was full of admiration. Although she was an adult, she was not as self-disciplined as Xu Jin.

Sometimes Xu Zhun didn't want to learn, but when he saw Xu Jin working hard, he would consciously follow along.

Both of them have their schedules fully scheduled, and only Xu Qiwei begins to feel lonely. His uncle used to play with him, but now he is studying all the time.

As soon as he came closer, Xu Jin treated Xu Qiwei as a student and started to teach him, which frightened Xu Qiwei so much that he was unwilling to come closer to them.

After the children started school, the family’s monthly expenses increased a lot, although some things can be bought nowadays.

However, Xu Xu still chose to buy pens and ink from Dayunchao. She always felt that modern pens and ink were not as good as those from Dayunchao.

Time passed while the children were busy studying. In October, Xu Ziqi's training was over and he wanted to go to the capital of Dayun Dynasty again.

This time, he mainly went to the medical clinic in the capital to exchange and learn. Doctor He wrote him a letter of introduction, so he could study directly with the doctors in the Rende Hall in the capital.

Xu Ziqing will also go along this time. Xu Xu thinks that if the children want to take the imperial examinations in the future, it will cost a lot of money.

Taking advantage of Xu Ziqing's return, Xu Xu discussed with her whether it was possible to buy a batch of goods in modern times and sell them in Dayun Dynasty.

"Sister Qing, when you go to the capital this time, do you want to bring some things to sell?" Xu Xu asked proactively.

Xu Ziqing looked at Xu Xu in surprise: "Why do you suddenly want to tinker with things from ancient times?"

Xu Xu smiled helplessly and said, "If the children want to take the imperial examinations in the future, they will need a lot of money."

Xu Ziqing nodded in understanding: "Indeed, studying in your place is really expensive. The road to the imperial examination requires not only talent, but also financial support. So, what do you want to bring with you?"

Xu Xu picked up a book about ancient life from the table, turned to the page introducing daily necessities and handed it to Xu Ziqing.

Said: "I think we can bring some things that Dayun Dynasty doesn't have, such as glass teapots, mirrors, pepper, etc. These things are very common in modern times, but they are rare treasures in Dayun Dynasty, and they should be able to sell for a high price."

Xu Ziqing took the book and looked at it carefully, with a hint of excitement in his eyes: "Last time my brother went there, he wanted to sell glass, but unfortunately I didn't go. This time, if possible, I would like to take a little of everything. But don't take too much, otherwise it will be worthless."

"Then how much do you think we should bring?" Xu Xu asked, feeling both excited and nervous.

Xu Ziqing thought for a moment and said, "We can test the waters first. Bringing about 20 pieces of each type of goods should be enough."

"This ensures the rarity of the goods while avoiding attracting too much attention. In addition, we have to pay attention to packaging and transportation to ensure that these things will not be damaged during transportation."

Xu Xu pondered for a while and said, "We can find some unused thin quilts. This way we can wrap it tightly and it won't get torn."

Hearing this, Xu Ziqing's eyes lit up and he said, "That's a good idea. I'll buy some thin quilts online later."

"So we have to take glass and pepper with us?" Xu Xu asked.

Xu Ziqing thought for a moment and said, "We can bring some exquisite glass teapots and some small mirrors. These mirrors can be made into various shapes and patterns, which should attract the attention of many women."

"Also, pepper is a good choice. In the Dayun Dynasty, pepper should be a very precious condiment that only the nobility can enjoy. We can bring some high-quality pepper over, and it should be able to sell for a good price."

Xu Xu smiled and said, "Then let's decide. We'll bring glass teapots, mirrors, and pepper. We'll bring ten different styles of glass teapots and mirrors, two sets of each style, and fifty kilograms of pepper. That should be enough."

"There are many kinds of pepper. In your Dayun Dynasty, the most expensive one is white pepper or black pepper?" Xu Ziqing suddenly asked.

Xu Xu thought for a moment and said, "White pepper. Dayun Dynasty probably doesn't have black pepper yet."

Xu Ziqing nodded: "Then bring white pepper, ten kilograms of white pepper."
