Daming: I, Yang Xian, really govern Yang!

Yang Xian's energy is now more focused on designing new warships. The silver mine in Japan cannot be left there forever, and Xu Da's illness is almost completely cured now.

The imperial court may send troops to attack Japan again at any time.

At this time, Yang Xian proposed a new warship plan to Zhu Biao.

There are two reasons. The first is that the research on steam engines at the Yangzhou Research Institute has finally made some progress these days, and in Yang Xian's opinion, it has completely reached the point of application on ships.

The second point is more important. After the previous battle, Japan is now more prepared for the Ming Dynasty. This time I am afraid that it will not be able to land as easily as the last time. In Yang Xian's view, a naval battle is very likely to occur.

The first large-scale naval battle between China and Japan had special significance in Yang Xian's heart.

In Yang Xian's opinion, this battle must not only be won, but also won beautifully!

It was against this background that Yang Xian chose to build a new type of warship.

As for the imperial court, Zhu Biao and Zhu Yuanzhang expressed their support immediately after learning about Yang Xian's suggestion.

After all, Ming Bank's business is booming now, and the court will not be short of money in the short term. It will not have to rely on coaxing and intimidation to get money from the Shen family like last time.

The requirements for new warships are, first of all, to be more convenient for navigation than existing ships today and to be able to cope with various sudden disasters at sea.

Yang Xian didn't want what happened in the former Yuan Dynasty to happen again in the Ming Dynasty.

Design drawings and so on, although it is most convenient to exchange them from the system and directly hand them over to the arsenal for production.

But in order to improve the capabilities of the designers in his military factory, Yang Xian called his designers over and prepared to let them participate.

Also coming to participate in the discussion on the design of the new warship were Shen Cheng, who now worked in the research institute under Yang Xian, and the twelfth prince Zhu Bai, who came from the capital with Zhu Biao.

Institute conference room.

Yang Xian began to draw the design in front of everyone.

On the huge blackboard, Yang Xian first roughly drew the outline of the new warship, and then began to divide it into details bit by bit based on the sketch of the ship.

Add other functions to the ship bit by bit, as well as the original parts and other parts required for this function.

On the podium, while drawing, Yang Xian explained to everyone present why these functions were added and the specific use of each component.

In order to let everyone understand better, Yang Xian drew the assembly diagram of each branch next to the warship sketch.

Every functional item has a very clear and detailed assembly design.

throughout the research room.

Only the "rustling" sound made by Yang Xian's drawing with chalk and his explanation voice alone.

Zhu Biao found that everyone except him was taking notes seriously.

It's just that the pens used by these researchers at the Yangzhou Research Institute are not calligraphy brushes.

The twelfth prince Zhu Bai, who was also taking notes, also discovered this, because he found that the speed at which he was taking notes was basically at the speed of Yang Xian's explanation. He put down the brush in his hand and looked at Shen Cheng, who was writing at a flying speed. And the long black rod in his hand.

Yang Xian noticed the gazes of Zhu Biao and Zhu Bai, so he could only stop and continue explaining, and said with a smile: "Xiao Cheng, give two pencils to His Royal Highness the Crown Prince and the Twelve Princes."

"Yes, teacher." Shen Cheng took out two graphite strips wrapped in cardboard from his arms and handed them to Zhu Biao and Zhu Bai respectively. Yang Xian said: "This is a writing instrument I recently invented. I named it pencil. It's just that it was invented not long ago and it's not a finished product yet. So it is currently only used by these researchers within the Yangzhou Research Institute. It is convenient for them to record research data on a daily basis.”

From a practical point of view, pencils completely beat brushes.

Whether it’s the speed of daily writing or the convenience of carrying.

Especially for these researchers.

When Yang Xian came to the institute one time and saw that the bodies of low-level researchers were covered in black ink, he thought of this.

Strangely enough, after he inherited this body, he also inherited his original abilities, so he could write with a brush very smoothly on a daily basis. Otherwise, this invention would probably have taken several years.

There were almost no difficulties or barriers to producing pencils in the Ming Dynasty. Graphite is not a rare material. You must know that my country's ink-making technology was already quite mature in the Song Dynasty.

The production method is also very simple. You only need to use graphite powder, add spices, and a little rosin to make spare ink.

Then put the ink into the pre-made circular groove mold, and finally put it into hot sand to disperse the moisture, and the pencil is completed.

Due to time constraints, Shen Cheng and the others just wrapped a piece of cardboard around the graphite strips and started using them.

In the later stage, you only need to ask the workshop to make wooden strips corresponding to the size of the pencil, then cut the wooden strips, and finally wrap the graphite strips and glue them together to create the pencils we will use in future generations.

Pencils have hardly changed since their birth.

Zhu Biao tried to write a few words with the pencil rolled up in the paper in his hand. He found that although the words written with it were not as elegant as writing with a brush, they were extremely simple and easy to use.

Indeed, as Yang Xian said, it is suitable for researchers to use for daily records.

The twelfth prince Zhu Bai on the side is now half a researcher, and he can't put it down every moment.

For researchers like them, no one understands the importance of the pencil more than anything else.

Of course, the role of the pencil is far more than that, but Yang Xian wanted to wait until it was completely produced before promoting it.

This day is not too far away, it should be in the near future.

For now, let’s focus on the warship.

If put together, the design drawings of various functional areas that Yang Xian had previously drawn on the blackboard formed the outline of a huge ship.

If it is just a general civilian or commercial ship, it will be considered complete at this step.

But Yang Xian designed a warship. Since it is a warship, it must have weapons!

Next, the next thing to design is the artillery.

In Yang Xian's view, the existing Ming Dynasty warships still have too few gun ports, which makes it impossible to create the naval battle scene he imagined.

Yang Xian not only wanted to increase the muzzle, but also increase the caliber of the cannon.

The chalk in Yang Xian's hand pointed at the warship drawn on the blackboard, and he looked at everyone and said: "Now our three-masted gunboat, the warship with the most cannons in the Ming Dynasty, has less than ten rows of cannons on both sides. As the main For a combat warship, this kind of firepower is completely insufficient.”

If anyone from the Japanese shogunate heard what Yang Xian said, they would probably have started to sweat. (End of chapter)
