In order to promote the increase of the literacy rate of Dajin, Zhao Ruxi tried to reduce the cost of production.

Moreover, no matter what, these technical things are brought by her and Xiao Lingyan from modern times, and they don't want to give people easy copycats.

So when they do it, they will make the technology grow to a certain extent, and the same is true of this little charcoal.

Although the charcoal pen she produced uses graphite as the core, it is still made of fine bamboo, and the natural grooves of the fine bamboo are used to clamp the graphite strips, and then wrap them around the line.

Such a pen is not sharpened like a modern pencil. When you can't use the pen, you have to untie the winding thread and push the graphite strip forward before you can continue to use it.

Although this is a bit troublesome, it is much more time-saving and labor-saving than grinding ink. If you don't write a lot of words and only use it for simple shorthand, you can use a piece of pen for a long time.

Anyway, in this era, soft pen calligraphy is still admired, and readers still use a brush to write. The selling point of charcoal is that it is convenient and cheap.

Because of the low profit, Zhou Chun said that the same charcoal appeared on the market, and she was still very surprised.

She looked at the charcoal pen handed over by Zhou Chun and found that the core inside was graphite, and even the hardness of graphite was about the same, so she knew that there was an inner ghost on Zhuangzi.

This cottage charcoal can't change the core, so work the appearance. The carved sandalwood is used to make the pen barrel, and the thread wound at both ends is also colored silk thread, which makes the charcoal pen go up a grade, and the selling price has also increased several times.

In this capital, where luxury and status are highlighted, there is also a market for such pens.

It's not difficult to check the ghosts and copycats, but doesn't Zhao Ruxi want to send points to the system? So I just used it.

As soon as the system heard it, it knew that 1,000 points was the news of the three systems just now; One hundred points is to inquire about this.

It follows Zhao Ruxi all day long, and of course it knows how capable Zhao Ruxi is now. Zhou Chun, the guys in the shop, and a few Chinese people can help her inquire about a lot of things, not to mention Xiao Lingyan.

Zhao Ruxi made money, except for keeping one percent for himself, all the others were given to Xiao Lingyan. Xiao Lingyan collected intelligence for Xiao Lingpu, and the intelligence network was spread very wide. Putting aside the friendship of the fellow villagers, as a collaborator, it is not too much for Zhao Ruxi to ask Xiao Lingyan to help check the news, and there is no problem of using or not using it, and not calling it. Judging from the exchange of interests, Zhao Ruxi is still the one who suffers.

The system thought about it and felt that judging from the degree of the host's slashing, this news could give it 100 points, which was very good.

Zhao Ruxi didn't pick the door, it didn't bargain anymore, and said happily: "No problem." ”

Then it was silent for a while, and when Zhao Ruxi finished practicing the words, it opened its mouth and told Zhao Ruxi the name of a Zhuang servant, as well as the name of Guo Jitong, the left attendant of the household department.

Zhao Ruxi wrote down these two names.

After remembering her name, she sighed, as if talking to herself: "I really want to know what kind of system those two are, whether they are the same as mine." ”

She propped her chin and looked at the scenery outside the window: "A thousand points for a message." ”

The system was very impressed to hear it.

It said, "One thousand five." ”

It didn't dare to ask for a price. Every time it asks for a sky-high price, it is returned to the floor by Zhao Ruxi.

So it also learned smartly, it only rose by five hundred, and it was ready for Zhao Ruxi to kill one thousand in one bite.

But I didn't want Zhao Ruxi to be very happy this time, so he said directly: "Deal." ”

"It's the old way." System Channel. Now it finally knows how to exploit the loopholes.

After discussing it with one person and one system, it was decided to write Zhao Ruyu first, and then write Xiao Lingyan.

Zhao Ruxi called Qingfeng in again and wrote the word "mentally retarded" first.

System: "......" I have a saying that MMP doesn't know whether to talk about it or not.

Seeing that it didn't speak for a long time, Zhao Ruxi tilted his head, stretched out his pen to the inkstone and dipped it, as if he was going to write it down, but there was a sound of feet stomping on the floor in his head.

Zhao Ruxi stopped his movements, twisted his eyebrows and thought for a while, then picked up his pen and wrote a line of words on the paper: "Wisdom makes you embark on a happy life (barrier-free) system." ”

Qingfeng read this line of words according to Zhao Ruxi's request, and then raised his eyes to look at Zhao Ruxi, his face full of doubts.

The girl is really strange today.

Zhao Ruxi didn't have time to pay attention to Qingfeng, but concentrated on feeling the movement of the system.

This time, the system didn't make a sound for a long time.

Zhao Ruxi looked at the line of words on the paper, and his face gradually became difficult to see.

She bit her lip and wrote two more words without giving up: "Storage." ”

As soon as Qingfeng finished reading it this time, the system quickly responded: "She's so stupid." ”

"Planting." Zhao Ruxi wrote two more words.

"She's so stupid."

Zhao Ruxi gritted his teeth and rewrote the first line of "Wisdom Makes You Embark on a Happy Life (Barrier-free) System" again. When Qingfeng finished reading, the system didn't respond again.

Zhao Ruxi slammed the pen on the table with a "snap".

Qing Feng was startled when he saw that his girl seemed to be very angry, and he didn't know if he had done something wrong just now. She hurriedly lowered her head and stood next to her and didn't dare to breathe.

She has been following the girl for so long, and she has never seen the girl so angry, and her face is blue.

It took a long time for her to see that the girl had recovered her strength, picked up the pen again, and dipped the ink in the inkstone. She quickly removed the paper that had just been soiled and laid a new sheet of paper on it.

This time, it was Xiao Lingyan's system that was asked.

Zhao Ruxi wrote the sentence just now, and the system immediately responded: "She's so stupid." ”

Zhao Ruxi's face softened slightly, and then continued to write: "Wisdom allows you to embark on a happy life (part of the obstacle) system. ”

As soon as Qingfeng finished reading, the system immediately connected: "She's so stupid." ”

Zhao Ruxi was stunned for a moment, his spirit suddenly lifted up, and he wrote the word "storage".

The system was silent again.

After thinking about it, Zhao Ruxi continued to write the word "planting". The system's "she's so stupid" continues to keep up.

Next, Zhao Ruxi wrote all the system properties she had seen in her previous life, what "counterattack system" and "plane system" were written, until the voice of the system became impatient. She just stopped the game.

It seems that Xiao Lingyan's system cannot be called a system, but should be space, only for storage.

But that's good. At least the weapons that Xiao Lingyan made could be transported to the border without realizing it. It's just that Xiao Lingyan is a prince, and it is more difficult to go out of Beijing.

Thinking back to Zhao Ruyu's system, Zhao Ruxi's heart still sank.

She asked in her mind, "Does Zhao Ruyu have the same time as me?" One thousand points. ”
