I am a child of Daqin Xiong, who supervises the country at the age of eight

Chapter 423 Inspection

After saying this.

He didn't dare to be negligent in the slightest, and dealt with it directly according to Ying Changsheng's instructions.

As for Ying Changsheng, he was also idle when he was idle, so he followed them together, watching how the charcoal was burning.

Speaking of which, burning charcoal is actually not difficult.

This is actually a relatively simple operation.

Only after some simple operations, the charcoal can be fired successfully.

I saw that this craftsman, according to Ying Changsheng's instructions, prepared a dozen long wooden sticks, and then took these long wooden sticks, lit them, and spread them on the wet turf, and began to let him perform shade burn.

In this situation.

White smoke billowed from the turf.

After a while, the craftsman made an appointment, and he said to Ying Changsheng that it was about time.

"Young Master Nineteen, it's almost ready now, why don't you open it and have a look?"

"well!"

Ying Changsheng nodded in satisfaction.

Immediately, seeing that Ying Changsheng had said so, the craftsman directly opened the turf in front of him without hesitation, only to see that there were a few wooden sticks that had been burnt into charcoal underneath!

Seeing Ying Changsheng, he was very satisfied, and he ordered people to quickly destroy these burning sticks, and then let them cool down.

Take out one, about the same length and thickness, and scratch it on the prepared paper aside.

Suddenly, there was only a clear and visible black mark left on the paper.

Seeing that Ying Changsheng was very satisfied, he couldn't help but nodded and said.

"Good, good, pretty good!"

"With this thing, you can successfully draw blueprints!"

With that said, Ying Changsheng began to perform simple processing on this charcoal pencil.

The processing method is actually very simple.

That is, on top of the charcoal pencil, roll it up with paper, so as not to get black charcoal dust on your hands when you use it.

Second thing.

What Ying Changsheng did next.

It's also very simple.

That is, sharpen the bottom of this charcoal pencil.

This scene was watched by Gongshu Shangzao, who was very curious, but after witnessing Ying Changsheng's operation.

Gongshu Shangzao was shocked.

He never imagined that there would be such an operation in this world.

At the same time, after successfully making a charcoal pencil.

Ying Changsheng didn't hesitate, he directly used the sharpened charcoal pencil on the white paper prepared in advance on the table beside him, and then started to draw.

All I saw was that the charcoal pencil was moving quickly in Ying Changsheng's hand, and within a short while, a perfect blueprint appeared on the white paper.

After seeing this drawing.

For a moment, Gongshu Shangzao next to him couldn't help being extremely shocked.

the reason is simple.

The drawings drawn with charcoal pens are not ordinary, and the drawings drawn with brushes can be compared.

At this time, looking at this extremely fine drawing, there is no slightest mistake on it.

For a moment, Gongshu Shangzao couldn't help but gasped, and said to Ying Changsheng in admiration.

"Young Master Nineteen is amazing, this charcoal pencil will definitely be of great use to my Great Qin!"

Saying that, Gongshu Shangzao carefully looked at Ying Changsheng, and asked Ying Changsheng.

"Also, Young Master Nineteen, can you let me take this charcoal pencil and give it a try?"

"of course!"

After hearing Gongshu Shangzao's questioning.

Ying Changsheng was very magnanimous, he opened his mouth and said with a smile.

"Okay, if you want to try, then try it!"

"Okay, I thank the nineteenth son, thank the nineteenth son!"

For a moment, Gongshu Shangzao's face flashed with ecstasy.

He nodded again and again, and then took the charcoal pen that Ying Changsheng handed over. After taking the charcoal pen, Gongshu Shangzao began to do simple drawing on the white paper beside him.

For a while, he undoubtedly found out.

This charcoal, when drawing on paper.

Can clearly and clearly draw the pattern that needs to be drawn successfully.

At this moment, he nodded in satisfaction and said to Ying Changsheng.

"Yes, yes, the nineteenth son is amazing. This charcoal pen, I ordered the craftsmen to make more, and then distributed it to the craftsmen under him. In this way, it can be easily drawn. It used to cost a lot. It takes a lot of time, a lot of work, to draw the blueprint!"

"Hahahaha, that's true!"

Ying Changsheng nodded in agreement.

After saying this.

But suddenly, he changed the topic and made a speech towards Gongshu.

"Okay, let's talk about the pen later, let's take a look at the blueprint I drew first!"

As he said that, Ying Changsheng pushed the successfully drawn blueprint in his hand to Gongshu Shangzao, and he looked at it.

The moment I saw this drawing.

Gongshu Shangzao couldn't help raising his eyebrows.

The blueprint drawn by Ying Changsheng is naturally impossible to be an ordinary blueprint, it is a three-dimensional three-dimensional blueprint.

However, looking at the conceptual drawing of the marine propeller above, Gongshu Shangzao looked surprised, and asked Ying Changsheng cautiously.

"Young Master Nineteen, is this propeller really as powerful as you said?"

"Such a small thing, installed at the bottom of the ship, can really push the ship to sail?"

"Why do you think it's unbelievable?"

"Haha, what you are worried about is indeed reasonable!"

Ying Changsheng nodded in agreement, but immediately, he changed the topic and said.

"However, in my opinion, it's purely groundless worry. If you don't believe me, you can try it back and see if the power provided by the marine propeller installed under this boat is more abundant, or the power provided by the huge paddle wheel more abundant..."

"This, how to try this..."

For a moment, Gongshu Shangzao said in embarrassment.

Well, he doesn't know how to try yet.

But Ying Changsheng has a way, he said with a smile.

"Of course the method is much simpler!"

"You can prepare two ships of the same size first!"

"Then, on these two ships, install the same transmission mechanism, and then, on the top of one ship, use a paddle wheel to propel it, and on the other ship, install the marine propeller at the bottom, and then send a strong man to the two ships respectively. One boat, to drive two boats to sail, so that when the time comes, see which boat runs faster during the sailing process, don’t you know?”

"This one……"

Hearing this, Gongshu Shangzao's eyes lit up immediately.

This, he realized, was an excellent solution.

After all, it would definitely be impossible to achieve this goal through other means.

However, this method is absolutely possible.
