Left the public to lose on the side of the building.

Win Changsheng thought of another thing.

This thing is nothing else, that is, now, he can't think of one thing.

The charcoal pen that I researched before.

It has been proven in practice and is very suitable for today's use.

There may be some artistry when writing with a brush, but its use is very constant, and it is very easy to cause in the process of using this brush.

Dysgraphia.

In addition, the area occupied by the paper when writing is also a bit large.

In addition to this, when writing with a brush.

It's also slow.

And writing is more laborious, because the brush is in the process of writing, the hand is suspended and held all the time.

When writing in such a situation, it must be quite laborious, and writing a few hundred words can make your wrist painful.

As a writing instrument in such cases.

The brush is not very conducive to development, not very conducive to writing, and not very conducive to the spread of culture.

Although this thing is a culture in its own right in later generations.

But even so.

The truth should be said when it should be said.

Win immortality at this time.

I think the brush is a very bad writing tool.

The cost of learning is too high to use, and the writing is too slow, in other words, it is not conducive to the current cultural promotion, let alone the current Great Qin, and the universal education of the empire is not conducive to the needs of the many writers in the Great Qin Empire.

In such cases, a charcoal pen is a great alternative.

But after thinking about it carefully, Ying Changsheng broke this idea again.

Charcoal pen even good.

But he also has a fatal flaw.

That is a charcoal pen made from charcoal.

If it is used for writing, it can easily lead to a problem.

The problem is that the written handwriting is easy to fall off, easy to be smeared, and easy to read clearly.

Therefore, Ying Changsheng felt that he had to invent a writing pen that could replace the brush for use, and this kind of pen must meet two requirements, that is.

First, use a hard pen to write.

Second, you don't have to use it once to dip the ink in the process of use.

And these requirements are said to be the easiest to meet with a pen, that is, a fountain pen.

But the crux of the problem is that the Great Qin Empire has not yet been born at this time, and the pen is there.

And the technical difficulty of making a fountain pen is not low.

Thinking of winning Changsheng here, he inevitably frowned.

But it soon dawned on him that he had an alternative.

This alternative is nothing else.

It is to make a simple fountain pen.

A more primitive fountain pen.

At this time, he said that he would do it to win immortality, and then he took action.

First of all, you need to make this thing, you need a piece of appropriate thickness, the thickness of the bamboo, you must control it, after preparing such a bamboo.

Ying Changsheng used alcohol and lit an alcohol lamp.

Alcohol was not a rare thing in the Great Qin Empire at this time.

The reason is simple, many raw materials such as sweet potatoes and sugarcane can be used to make wine.

Alcohol is such a thing.

In this way, how could the Great Qin Empire be short of alcohol at this time, after having alcohol, he could successfully ignite the alcohol, and then heat it to heat the bamboo.

I saw only the alcohol lamp, under the burning flames.

The moisture in this bamboo is quickly dried.

There was even a cyan liquid dripping out of one end of the bamboo.

This may be the sweat in the hands of literati and ink writers.

At this time, as these liquids are gradually evaporated into the air, the water is removed from the bamboo, and the surface of the bamboo is also carbonized to a certain extent.

It makes the bamboo a little stronger.

In such a situation.

Win Changsheng also started the next step, he used a small saw to slowly cut off the bamboo, and then after selecting it properly, he carefully opened the top of the bamboo, drilled the hole, and quickly expanded.

Immediately, after cleaning.

Win Changsheng, took out another branch that had been prepared in advance, made a wooden plug of a suitable size, and then stuffed it in, tried it, and it could indeed be completely sealed.

He subsequently.

Use a small drill bit at the bottom of this bamboo.

A small opening was made.

In this way, the most important thing needs to be made.

That's what you use to make nibs.

Speaking of which, the best way to make it is to use a hollow iron pipe, a hollow thin iron needle, the tip is directly smooth, and the thickness is well controlled.

You can control the ink, slowly flow down the iron pipe, and then write, but the problem is that the technology to make such an iron pipe is too difficult.

So, after thinking about it, Ying Changsheng decided to make a simple nib.

It is to use wood to carve out a pen tip similar to a fountain pen, and draw a thin groove on it, so that the ink can flow out.

Of course, such a nib is actually not very durable.

Probably, after using it for a while, you have to replace it!

But it's not impossible.

I had no choice but to use such a method.

At this time, he only saw Win Changsheng, and he acted quickly.

It didn't take much time.

With a few simple wooden nibs, it was successfully made.

Then, Ying Changsheng carefully put the nib of the pen on, and then he quickly poured some of the most delicate black ink into the barrel, and then stuffed the top of it with a wooden stopper.

Win Changsheng, on the desktop next to him, writing.

The simple fountain pen, although the production is extremely simple, but his use is also very convenient, and the effect is quite good.

I saw that after Ying Changsheng finished making this simple fountain pen.

On the side, dozens of words were written in one breath, and there were no accidents.

This scene made Ying Changsheng smile with satisfaction, and said with frequent bows.

"Yes, yes, with this thing, it will be much easier to write in the future!"

Win Changsheng's voice, the moment it fell.

He immediately used the cap made from thicker bamboo in advance to put up this simple fountain pen.

A pen made from this bamboo.

After putting it in my arms.

For a while, Ying Changsheng got up quickly, and immediately planned to take this pen to meet Brother Zheng, and then, recommend this pen to Brother Zheng's old man, so that his old man can realize the usefulness of this thing.

Inside the Zhangtai Palace.

At this time, Brother Zheng was reviewing the recital.

At this moment, Ying Changsheng strode in.

When Ying Zheng saw the latter come in, he couldn't help but smile, then put down the brush in his hand, and by the way, moved his wrist again.

Well, review the folds.

It's really tiring.
