My whole family is in the book, I'm cheating, the female supporting role in the control group i

Qin Yan finally understood: "So, if I just exchange things, it will be very cheap, but if I exchange the production method of something, it will be more expensive. For example, if I want to exchange the hybrid seed technology now, it will be more expensive."

Xiaojun: "Yes, and this kind of thing will only appear in the mall if you, the host, bring it up. If you don't bring it up, there won't be these things in the mall, and you won't be able to see them."

“Most of the things that appear in the mall are real objects.”

Qin Yan understood.

So, this system mall is keeping up with the times.

Give her whatever she needs.

In fact, this is quite good.

Qin Yan: "But why can't these technologies appear directly in the system mall?"

Wouldn't it be better to let her choose for herself?

After all, sometimes, if she didn't see it, she might not even remember whether such technology existed.

Xiaojun: "This is mainly to prevent things from appearing beyond your cognition, and to prevent the world from evolving too quickly. If this happens, the world will still collapse."

Qin Yan didn't quite understand: "What do you mean by something beyond cognition?"

Xiaojun: "To put it simply, in ancient times, there was no such thing as a telephone. They believed that only gods could communicate with people thousands of miles away. For them, mobile phones were beyond their cognition."

"It's something they can't imagine out of thin air."

"The reason why I found you in your world is because the level of technological development in your world is acceptable to this world. In other words, if you want to introduce technology from that world into this world, it will generally not reach the point where it causes this world to collapse."

"But if all the things in the mall that belong to the main world are put out, then there will be things beyond your cognition. Many of the things and technologies in the main world have exceeded the limit that this world can bear."

Hearing this, Qin Yan seemed to understand a little bit.

She seemed to understand, but also seemed not to understand so well.

Xiaojun: "So, in order to prevent the appearance of things beyond your knowledge, these technical things will not appear directly in the mall."

"After all, this world is just a small world that is about to take shape, but it may collapse at any time. They cannot afford the technology of the main world."

Qin Yan: "So according to what you mean, the world I came from is actually of a very low level."

Xiaojun: "Actually, it's about the same, just a little more advanced than this world."

Xiaojun's voice sounded somewhat helpless: "If it weren't for the fact that we were not trying to ensure that the technology capabilities that this world could withstand would not appear, in fact, if we were looking for a host of a higher world level, the mission in this world would not be so difficult to complete."

Qin Yan: “…”

So, sometimes it’s a good thing that our world level is low!

Qin Yan: "Then what is the technological capability that this world cannot bear?"

Xiaojun: "As long as you can think of it, it is within the range that this world can bear."

Qin Yan: “…”

Oh, she suddenly isn't very happy!

Forget it, she decided to give up talking to Xiaojun.

If she continued talking, she was afraid that her heart would be filled with a thousand horses galloping, all of them like alpaca!

"Sister, do you have anything else?"

Mi Qingxue stared at her sleeve curiously.

She felt that her sister definitely had a magic trick up her sleeve.

Otherwise, why did she take things out of that sleeve every time?

"No more, no more. If there's anything you need, you can tell me. If I have it, I'll bring it to you." Qin Yan quickly covered his sleeves.

She was afraid that Mi Qingxue would pounce on her and flip her over.

Every time this girl shows this kind of look, she almost always intends to rob something.

She was afraid of this girl.

When she was a child, this girl often took away some of her things.

At that time she was very depressed, wondering why her sister was so naughty.

But as she grew older, her relationship with Mi Qingxue became better and better.

Especially, her sister, she really is like her most loyal servant...

It has been many years since she saw Mi Qingxue look at her like this.

But now that she has seen it, she should be on guard.

"Oh, I see! All right then..."

There was a hint of disappointment in Mi Qingxue's eyes.

Seeing this, Qin Yan finally breathed a sigh of relief.

It looked like she wouldn't rush over and roll up her sleeves.

"It's like this, sister. After coming to this world, I feel that my skin is not very good. Can you get me a set of skin care products?" Mi Qingxue said, touching her face.

"I like and am satisfied with my own face in this world, and I hope it can last longer."

In her previous life, she looked like an ordinary person, but her sister Qin Yan was very beautiful.

Generally speaking, she is more like her dad, and her sister is more like their mom.

Yes, that’s right, back then, their dad was able to trick their mom back home simply by relying on his talent!

Fu Rong in this life is actually quite good looking.

If their mother were to come into this world, she would definitely be very satisfied with their father's new image.

Qin Yan looked at her now delicate skin and was silent for a moment: "At your age, you probably don't need any maintenance."

"No, no, no, sister, you don't understand this. I've lived two lives, and I know very well that if you want to maintain your appearance, you must start from a young age. If you really get wrinkles or something like that, it will be too late."

Mi Qingxue said seriously: "Even those Chinese medicines that regulate the body's condition cannot restore a person's condition to the original state. They can only make wrinkles grow a little slower. It is absolutely impossible to eliminate wrinkles that have already appeared."

"So, in order to prevent my wrinkles from appearing so quickly, I have to start preventive maintenance early."

Qin Yan was a little surprised: "Is that so? I thought I had to wait until I was older before I could start taking care of myself!"

"Of course not. If that's the case, it's too late." Mi Qingxue was very sure: "Sister, after all, you haven't lived to a very old age. It's normal that you don't know this."

Qin Yan nodded: "That's true."

She now has the mental state of an eighteen-year-old.
