After the kiln and paper mill got the formula, they began to mix the raw materials according to the recipe and prepare for trial production.

There are five kinds of things that Su Jinli has to make, among which the bathtub, flush toilet, pencil and cement have to be made by the porcelain kiln factory, because they need to be fired.

The paper mill only needs to trial produce Yunrou paper, that is, toilet paper, which is naturally much easier.

The owner of the kiln factory had to divide the factory men into four groups, each of which was responsible for the same thing.

Among them, pencils are the easiest to make, so after only two days, the pencil group made a qualified pencil.

Su Jinli only gave a pencil formula, and the pencil lead produced was soft, and it didn't need to be particularly hard when writing, and it was not easy to cut the paper, and the handwriting was still very black.

After trying it out for himself, the owner of the kiln factory quickly understood the advantages of this pencil.

So he decisively found two delicate sandalwood boxes and came out, put the finished pencils neatly in them, and sent someone to send them to Chu Yan and Su Jinli.

Chu Yan had been waiting for the finished product to be made, but he didn't expect it to be so fast, and he was stunned for a moment when he received the pencil.

Chu Xuan was also there at that time, and when he saw that he had received a box, he was so curious that he urged him to open the box and take a look.

Chu Yan glared at him with disgust, and then opened the box and checked the contents inside.

Su Jinli drew a pencil on the recipe, so when he saw the pencil, he wasn't too surprised.

Chu Xuan glanced at it to the side, a little curious: "This is the pencil?" Is it made of lead? ”

Chu Yan had read the recipe and knew that this pencil was made of graphite and clay, so he glared at Chu Xuan with special disgust, and was about to pick up the sharpened pen in the box to practice.

Who knew that Chu Xuan actually took the first step to pick up the pen and scratched it on the paper.

Black lines are instantly drawn on the white paper.

Chu Xuan was a little dumbfounded: "Huh? You can really write! ”

As he spoke, he was going to try writing a few words.

So I habitually adjusted the posture of holding the pen, just like writing with a brush.

However, when Chu Xuan tried to write, he was dumbfounded: "Huh? Why can't you write it? ”

Chu Xuan exclaimed, but he was not stupid, and quickly adjusted the posture of holding the pen.

After a few attempts, he finally found the right posture to hold the pen and wrote smoothly.

It's just that he is used to writing with a soft brush, but now that he has changed to a pencil, he always can't control his strength, and the words he writes are not good enough.

Chu Xuan tried it for a while, and when he saw that the words written were too ugly, he was a little disgusted: "What kind of pencil is not easy to use, it is not as convenient as a brush." ”

Chu Yan snatched the pen in his hand, secretly tried the feel while he was not paying attention, and then tried to write on the paper, and wrote beautiful handwriting at one time.

Chu Yan silently took the words written by Chu Xuan for a while, and felt that his words looked much better, so he said with disgust: "Who said that this pencil is not easy to use?" It's clear that you're too stupid to use it. ”

Chu Xuan was a little unconvinced, but as soon as he saw the words written by Chu Yan, he couldn't refute it.

Chu Yan saw it in his eyes, and was secretly proud in his heart, and then said: "Do you know how much such a pen costs? ”

Chu Xuan was dumbfounded, where did he know this!

Chu Yan continued to taunt his stupid brother, and at the same time showed off a little: "This pencil is made of thin wooden sticks, graphite and clay, and it takes a very short time to make.

The pencils in the box only took two days, and this time it was only an experiment, so there was not much to do, and if the scale was expanded, thousands or even tens of thousands could be made in two days.

What's more, this pencil does not need to be dipped in ink to write, does not need to be polished, and can be written at any time.

You should know that writing requires the four treasures of the study, and pen, ink, paper, and inkstone are also indispensable.

These things cost a lot of money, even the worst pen, ink, paper, and inkstone, and the poor can't afford it.

But with this cheap pencil, even the poorest families can afford it. ”

Chu Xuan was dumbfounded when he heard this, he looked at Chu Yan dumbfounded: "Brother, if this is true, it is a great merit!" All the people of the world have to thank you! ”

Chu Yan laughed proudly and said beautifully: "This pencil was actually thought up by your sister-in-law.

She doesn't know how to grow her little brain, but she can come up with such a wonderful pen! ”

Chu Xuan: "......"

What's going on with the sudden desire to beat the second brother?

The second sister-in-law can come up with delicious dishes, even if she can come up with a pencil!

Father's vision this time is also too good.

Chu Xuan's heart was sour, who knew that Chu Yan was still showing off: "Your sister-in-law has come up with several interesting things recently, but unfortunately only the pencil has been made, and the others are still being trial-produced." When those things are done, the second brother will let you see and understand. ”

When Chu Xuan heard this, his heart became even more sour, and he couldn't help but remind him: "Second brother, she hasn't passed the door yet, it's not appropriate to call her sister-in-law now, right?" ”

"What's inappropriate?" Chu Yan glared at him dissatisfied, and suddenly narrowed his eyes suspiciously, "What do you mean by this?" Do you want to ......"

"Little brother didn't think about anything!" Chu Xuan was so frightened that he hurriedly said, "Second brother, the younger brother is just reminding you that it is important to set the wedding date quickly." ”

"You're right, I'm going to see my father."

After Chu Yan finished speaking, he immediately entered the palace with the box.

Chu Xuan cheekily followed.

……

The Imperial Palace, the Palace of Diligence.

Emperor Yong'an is criticizing the folds again.

He quickly finished reading a book, drew a red cross on the back, threw it away, and picked up a new fold to open it.

Seeing the signature, Emperor Yong'an was stunned for a moment, and muttered to himself: "Su Xin? How did he hand over the fold? Is something going on? ”

Emperor Yong'an opened the fold a little nervously, and when he saw the contents inside, his face instantly darkened.

"Su Xin, bastard!"

He was so angry that he had a bit of a loud voice.

Su Jing stayed outside, and when he heard this, his heart sank instantly.

Something happened to my father?

Su Jing's face turned a little pale.

At this moment, he saw Chu Yan coming over, and he couldn't help but secretly breathe a sigh of relief.

My sister is the fiancée of King Qin, if something really happens to my father, Your Majesty should look at King Qin's face, and he should be open, right?

When Su Jing thought about this, his eyes looked at Chu Yan a little more eagerly.

After Chu Yan noticed it, he immediately became vigilant.

What kind of eyes is Su Jing?

He hadn't heard that Su Jing had a special hobby.

Chu Yanhu walked over suspiciously, saying that he had something important to ask to see Emperor Yong'an.

Soon someone went in to tell you.

Then Chu Yan was called in.

Chu Xuan cheekily followed in.

Emperor Yong'an raised his head, and as soon as he saw Chu Yan, he remembered Su Xin's proposal in the compromise.

So he couldn't help but want to tease his son.

He deliberately asked: "You came just in time, Su Xin handed over the fold, saying that he was sick and wanted to go home to recuperate, and proposed to let you go to military training, what do you think?" ”
