"Zhang Zhong, Zhang Zhong, come quickly."

"Here, sir, what are your instructions?"

The butler Zhang Zhong ran out quickly.

This word "Loyalty" was a word, in ancient big families, only the most trusted servant could receive the letter from the master.

Therefore, just like Chen Yu's mansion when he transformed into Ye Gong, the old servant Chen Zhong was the old housekeeper.

The name of the housekeeper of this Zhang Mansion is also Zhang Zhong.

"Hurry, go to the kitchen and get some carbon."

"Ah, master, what do you want carbon to do? I'm afraid that the miscellaneous items will pollute your study."

"Take it as a pen and go quickly."

"Yes...but, sir, do you want wood carbon or stone carbon?"

"This..." Zhang Sengyou turned his head and looked at Chen Yu.

Chen Yu was stunned. He didn't know what kind of carbon should be used as a pen in this ancient times, but when he recalled the refills in modern pencils seemed to be stone carbon?

"Stone Carbon."

After a while, Butler Zhang brought stone carbon. Zhang Sengyou didn't mind being dirty. He stepped forward and grabbed a slightly thin-sized stone carbon as a pen, took it to the desk and started to try to draw.

Sure enough, this test made him look exquisite.

"It's the extreme, it's the extreme, it's indeed the most suitable for drawing sketches as a stone carbon brush."

"But, this thing is too dirty, do you have a good idea?"

Chen Yu smiled, but didn't stop him, and spoke out how to make the pencil.

After hearing this, Zhang Sengyou shook his head and said.

"With stone carbon as the core, wrapped in fine wooden sticks to make a pen? So that's it..."

"This method is not a vulgar, and it is very difficult to make without skillful craftsmen."

"However, no matter how difficult it is to be controlled, it must be controlled."

After saying that, Zhang Sengyou excitedly threw away the stone carbon in his hand and hurried out.

With the ancient craftsmanship level, it is naturally extremely difficult to make a pencil of modern craftsmanship. The refill core, pen body, and how to combine the two are all difficult.

But if you really have to do it seriously, you can do it.

You can't underestimate the manual skills of ancient craftsmen.

Just three days later, Zhang Sengyou was already holding the first hand-made pencil of an ancient craftsman in his hand.

No, it should be said to be a stone carbon pen.

However, this stone carbon pen is extremely large, and it is actually three fingers wide. The refill in the middle is also outrageous, and it is actually as thick as a thumb!

It can be seen how rough this ancient stone carbon pen is.

"Chen Yu, Mr. Chen Yu, you are right. As expected, this stone carbon pen is the most suitable for sketching."

Zhang Sengyou held this large stone carbon pen and looked excited like a child who had just got a toy, dancing and painting.

"And, using this stone carbon pen to paint has a stronger texture, and it is easier to control the importance and urgency. The only bad thing is that the stone carbon pen core is too brittle and will break if you are not careful."

"Come on, how do you see this?"

Chen Yu said the truth:

“It’s big.”

"Big?"

"No, the smaller the stone carbon pen, the better"

"At least the thickness of the little finger is appropriate. The refill is about the size of a Wushu... No, no, no, the tongue is wrong. I mean the toothpick size is good, otherwise it is too big and not controlled."

"The pen body has a thumb, the size of the toothpick in the refill core...what is the toothpick?"

This made Chen Yu ask. He had obviously used toothpicks in the Zhang Mansion.

"That's it, it's the thing I used when I picked my teeth that day. Isn't that toothpick?"

"That's a tooth pick...but it's appropriate to say it's called a toothpick."

Ancient knowledge: Lu Yun, a writer of the Jin Dynasty, said in a letter to "Book of Brother Pingyuan" that when he was reviewing "Cao Gong's artifacts", he saw something like crowns, combs, teeth picking fibers, etc.

"Cao Gong" refers to Cao Cao at the end of the Han Dynasty;

"Fiber" means "tie", "tie-clearing fiber", which means toothie-clearing stick.

"But I think it's already usable at this size."

Chen Yu shook his head and said, "Master Zhang, you think it is suitable because your painting skills are extraordinary. You can control such a large pen, but ordinary people cannot. Not to mention drawing sketches, it is probably very difficult to even hold it tightly."

Zhang Sengyou was stunned when he heard this, and thought that this was indeed the case. With his painting function, this stone carbon brush is difficult, and most people will definitely not use it well.

But who is Zhang Sengyou? He is a fool who loves painting. He gritted his teeth and nodded.

"I see."

"Chen Yu, continue practicing calligraphy."

After saying that, he left with a stone carbon pen.

Chen Yu asked curiously:

"Sir Zhang, what are you going to do?"

"I want to learn how to make pens by Sun Dajiang. I want to improve the production of stone carbon pens."

"You said that the smaller the stone carbon pen, the better. Then I want to make a toothpick-sized stone carbon pen."

Yes, Zhang Sengyou also worked hard to draw.

Chen Yu doesn't care about this, just keep practicing calligraphy.

Time passed day by day, and Chen Yu stayed at the Zhang Mansion gate every day without leaving, and did not step into the two gates, just practiced calligraphy.

Every three or five days, Zhang Sengyou would come and take a look, give him some of his calligraphy skills, and take out the latest stone carbon pen.

With intention, the stone carbon pen made by Zhang Sengyou became thinner and thinner, and the refill core gradually approached the size of a Wu flag, oh! It was the size of a toothpick.

Chen Yu had to accept the ability of skilled craftsmen in ancient times. In just two months, Zhang Sengyou worked hard to invite the master craftsman who made the pen, and actually made a stone carbon pen close to the size of a modern pencil by hand.

But the price paid is high enough. Such a stone carbon pen, including the manual fee, costs at least ten taels of silver.

This is the result of the low status of ancient craftsmen and meager salary.

Such a stone carbon pen is a consumable and it won't take long, but it's expensive.

Although Zhang Sengyou is famous, he is no longer an official. The income and expenditure in the mansion was originally only more than ten taels of silver per month, but now it is almost double the expenses, but it is a bit tight.

Although the family's wealth and wealth that I left behind were still large, they could not lose like this day and month.

Even Butler Zhang looked at Chen Yu with a bad look.

After all, in the eyes of Butler Zhang, Chen Yu was a fake monk who came to Zhang's house to cheat for food and drink, and he had a lot of complaints about him.

After Chen Yu learned about this, he also felt that it was not good to live in Zhang Mansion for free and eat, so he had to pay a little rent.

After all, we are the protagonist of a time traveler. If a servant treats him like this, his face is not good-looking.

So on this day, he took the initiative to find Zhang Sengyou.

"What? Are you going to sell paintings on the street?"

"No, you haven't achieved practicing calligraphy yet. What qualifications are you qualified to sell paintings and finish the finishing touch? Don't you want to learn it?"

Chen Yu said firmly:

"Of course I still have to practice the words."

"If you sell paintings, I will only draw three sketches outside the Zhang Mansion every afternoon, one or two silver coins."

"You want to sell sketch portraits? This... you are qualified to portray people with your sketching skills."

"Well, you mean it, and I don't want to persuade you."

Chen Yu shook his head and left with satisfaction.

This is a matter of killing two birds with one stone. One is to relax and rest, and the other is to earn some living expenses.

Let Zhang Zhong see, we are not the ones who cheat people of eating and drinking.

Then ten taels of silver were thrown into his hands and said that this was the monthly rent and living expenses of his mother. What else would he say?

After Chen Yu left, Zhang Sengyou shook his head funny. Zhang Zhong's mouth was broken. He knew it, but he didn't expect Chen Yu to react like this.

"I don't want to be a person with a temperament, whether it's a person who has the finale, but I don't want to give the finishing touch. "
