In the past month or so, Sima Pianpian has basically gone to the science and technology area every day to study several minerals with Xing and others, and these minerals are all with unknown marks, and researchers can't study how to use these minerals anyway, and it's useless to bask in the sun like varnish, Sima Pianpian hasn't had any major events recently, and she also went to help them find a way, she also wants to know what these substances are, maybe they can be processed with energy, like a light bulb, how practical is it?

And after many practical years, she finally gained the use of two substances.

One of them is a kind of black spar, which is a small diamond shape with a regular side length of 1 cm, which is also Sima Pianpian found from a remote underground cave a year ago and handed it over to the scientific research team for research.

This substance has also gone through many different realities and has not reacted. After Sima Pianpian passed, he guessed that the biggest possibility of a substance like this is that it is a special substance that can only be processed with energy, and as long as you find the excitation process of natural energy such as sunlight on varnish, you can use it.

This substance is stimulated by ice and snow, and it takes more than ten days to bury it in ice and snow, and the researchers have tried, the ice in the ice warehouse is not good, and it must be used in nature, it is because of such harsh conditions, so the previous real yàn will not have any effect, the season has not arrived!

In snow and ice, the substance emits a rainbow-like luster, which also means that it is activated.

Sima Pianpian named it color ink, incorporated it into the warehouse, and after the spatial analysis of "energy processing", it was concluded that the recommended uses were - calligraphy and painting. As soon as she heard about this purpose, she knew that it should be similar to the function of a pen.

After learning about the products that have been manufactured. She named it "magic pen", and at the same time couldn't help but sigh to herself, this is really, a stroke in hand. Don't worry about writing......

The shape of the magic pen is a black stick with the thickness of a pen barrel, 18 centimeters long, and the outside is the same as a light bulb, which seems to be wrapped in a layer of invisible spiritual energy, a thin layer. There is also a sense of touch, it is impossible for people's hands to directly contact the substance inside, this magic pen is of course not Ma Liang's, and it does not have such a magical function, but it has a very practical function, that is, you can switch the pen you want at will, the same as the light bulb, as long as there is energy, there are points. It can be used forever without worrying about running out of ink and without damage.

It's used in a similar way to a light bulb, and it's also used for recharge time, but its price settings will be different, different pens, different prices, and it even includes an eraser, which can be used for 1 point at a time. Wipe it off.

There are a total of seven kinds of pens inside, pencils, pens, brushes, chalk, crayons, watercolor pens, and highlighters, most of which are at different prices.

Pencil. The cheapest price is 1 point for 10 minutes, and only 6 points for an hour is enough, and the school children's own points account should be enough, and no matter how long it takes, no matter who writes. The marks left by the pencil can be erased with an eraser, while most other pens will have limitations.

Fountain pen, the price is 3 minutes and 1 point, after writing, it can only be erased by the pen that is written, and other pens are not good, and the time is not limited.

Brushes and crayons, the price is 1 point per minute, and they can only be erased by the pen within the day of writing, and they cannot be used after the time is exceeded.

Chalk, the price is 3 minutes and 1 credit, and the way to erase it is the same as that of a pencil.

The watercolor pen, the price is 1 minute and 2 points, and it can only be erased by the pen within an hour of writing, and it cannot be written beyond the time.

Highlighter, the price is 5 credits for 1 minute, and it is erased in the same way as a watercolor pen.

Since you can switch the type of pen, of course, some of its characteristics will also change with these pens, for example, the pen cannot write on the rough stone wall, the chalk can draw lines on the cloth, the words written with the highlighter will shine, and so on.

The best thing about the magic pen is not only the switching of these pens, but also the following three points:

First, all pens can be arbitrarily selected in color, and it comes with a color module, which is very rich in color like the "Paint" function in the system.

Second, the color transparency can be adjusted, from completely transparent to completely opaque.

Third, you can adjust the size of the refill and grasp the thickness of the pen.

The main thing is that these are free!

When using the magic pen, every time you switch, the magic pen will show a different shape, but the real change is the pen head, it will change the pencil head, brush head, chalk head and so on, and the shape of the pen will not change, but it will change the color with the change of color, and the touch is the same, cool, slightly elastic, so the change should be the role of the outer layer of spiritual energy, it is a simple little illusion.

The same magic pen is automatically memorized and saved for switching, that is to say, if the time of the pencil is charged this time, it has not been used up and switched to the pen, then the next time it is switched, the time is still saved, and the magic pen can also be turned off, after it is closed, it has become such a black inconspicuous stick again, and the next time it is opened, it will automatically display the pen type when it was closed last time.

After that, Sima Pianpian went to the cave again, and got a lot of this kind of resource back, these caves she wrote down before, and then she made tens of thousands of magic pens out, this time she didn't dare to send them all, only sent them to the children, and other people who need to use pens at work, the previous hundreds of thousands of light bulbs have accounted for a lot of her energy, she doesn't know if there are more practical products in the back, this is just a little bit first.

With this pen, the clansmen will write much more conveniently, but also beautiful, the previous carbon ink pen is the same as a brush, how many years did primitive people learn to write? It doesn't look good to write it at all, and it wastes paper, and she has also had the heart to find a stone mill before, and wants to make a zuò pencil to see, but she has not found it, so she can only regret it until now, and now it has finally been solved.

The reason why this kind of mineral appeared in the other world, she thought about it, either that force had controlled this planet for too long, and many mineral resources had mutated in the direction of spiritual energy, or maybe this planet was born to use spiritual energy to develop......
