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

But since her sister said that she also had skills for other weapons, she felt relieved.

Wait until she goes back to try them out and find a weapon she likes best.

"But sister? I remember you didn't understand these before! Why can you come up with so many martial arts secrets now?" Mi Qingxue asked curiously.

"Maybe it's because I died saving people in my previous life, so this is a reward from this world."

Qin Yan had already fooled his father, so he had no psychological burden at all to fool his sister now.

"You can think of it as my golden finger."

Mi Qingxue suddenly understood.

That's it!

Just say it!

Why is it that they are clearly in a world in a book, and the heroine in this world should be Ye Liuwei, but her sister knows so much about Ye Liuwei.

Now it seems that her sister is the new heroine of this book, or maybe her sister was chosen to save the world.

And those who also appear here should be here to help my sister.

So, can we now say that her sister is the new heroine of this book?

I have to say that Mi Qingxue is worthy of the fact that she has read quite a few novels in the past.

This speculation is very close to the truth.

Unfortunately, she guessed one thing wrong.

That is, Qin Yan is not yet the heroine of this world. The heroine of this world is still Ye Liuwei.

However, the halo of the heroine above her head is fading little by little.

As a result, many things in this world will be changed.

There have been many people who were selected before, but they all ended up in miserable defeat.

All I can say is that the heroine in this world is not fixed, and there is no so-called heroine in this world.

It is a world where the self exists independently. When people make different choices, the world will also become different...

Of course, the essence of her guess was correct.

Qin Yan’s mission is indeed to save this world that is about to be destroyed by the heroine.

"Sister, does your golden finger have other uses? Like flying?" Mi Qingxue asked curiously.

"No, but I can give you this."

Qin Yan took out a package from his sleeve and motioned Mi Qingxue to open it.

Mi Qingxue took the package curiously and opened it. When she saw what was inside, she couldn't help but cheered: "Ah, sister, thank you so much, how did you know I needed this so much?"

Sanitary napkin!

God knows, as a girl, after being accustomed to the convenient era in my previous life, after coming to this world, what I can't stand the most is actually the sanitary conditions here.

Especially during her menstrual period every month, she feels really uncomfortable.

Even though she was a princess, she only used the best.

But it is still not as good as the things used in the previous life.

Unexpectedly, her sister actually had sanitary napkins.

This is really great news!

Mi Qingxue was almost dying of excitement.

Actually, over the years, she also made some simple sanitary napkins by herself, but her hands-on ability was so poor that they definitely did not sell as well as those merchants in her previous life.

I didn’t expect it! I didn’t expect it!

Excited and happy, Mi Qingxue even wanted to spin in circles excitedly!

As expected, her sister was the only one who understood her best, and she was so excited.

Seeing Mi Qingxue's happy expression, Qin Yan couldn't help but smile and took out another small metal box.

"This is for you too."

"This is……"

Looking at the familiar metal box, Mi Qingxue opened her mouth uncertainly.

"Is that what I think?"

"Yes, it's what you think!"

Mi Qingxue cheered, took the metal box, opened it and saw that the contents were indeed a set of brand new scalpels of various styles and sizes.

In fact, many details were more advanced and delicate than the scalpels she used in her previous life.

There is still a lot of room for improvement in the technology used to build this world.

It took countless skilled craftsmen to make her set of silver needles.

However, the requirements for the scalpel she needed were too high, and the craftsmen in this world were really unable to make it for the time being.

did not expect……

Isn’t it here?

Moreover, it even looked more high-end and detailed than what she needed!

Seeing Mi Qingxue's happy expression, Qin Yan was also in a very good mood.

She has more points now, so it should be no problem for her to exchange some of these things.

What's more, the points for small items like this in the mall are particularly good.

For example, for sanitary napkins, one point can be exchanged for a lot of them.

This was just what she exchanged for 0.01 points.

The main thing is that if she changes too many at once, it would be a bit excessive for her to take them out, and they would not be able to be stored.

Her system has not yet evolved to the point where it can have storage space.

Xiaojun just told her that she could make purchases based on a few tenths of a point.

And this set of scalpels only cost her five points in total.

Xiaojun: "These things are not very valuable to the mall, because they were really too common in our time."

The world in which this system is designed must be a more high-tech world.

That’s why we can interfere with the cause and effect of other worlds.

It can also be called the main world.

This main world may be a divine world like the one for cultivating immortals, which has the ability to create. It may also be a world that has the ability to create when technology develops to a certain level.

In fact, in some ways, the two are connected.

The main world that Xiaojun came from is the main world developed by science and technology.

Therefore, things like martial arts secrets will require more points, while things like products of the technological world will require very few points.

Moreover, the technological world is the technological world, so there will be martial arts secrets and the like, but there will not be things like cultivation techniques.

Qin Yan: "That means if I want to exchange points for something in the future, this kind of thing is actually very cheap."

Xiaojun: "That's right. Besides, some food and other things will be cheaper."

When Qin Yan heard this, he curiously went to check the mall page.

you do not say!

Only one point is needed to buy 500 kilograms of rice, which is a terrifying amount.

You have to know that in ancient times when productivity was low, even a county government office might not be able to store so much grain.

Xiaojun: "And things that can change the productivity of an era will be more expensive."

After a pause, it said, "For example, the method of making glass that you exchanged last time is one of them."
