Beijing, Changchun Palace

The topic of Zhu Youzhen's brothers returned to the boat.

After discussion, Zhu Youzhen found that Zhu Youxiao was not considering the Song boat model at all. His series of questions revolve around the real Song boat. Zhu Youxiao seems to want to copy Song Chuan. Then the amount of work will be huge.

In order to dispel Zhu Youxiao's thoughts, Zhu Youzhen greatly refuted his views from the material.

Zhu Youxiao's understanding of materials is still stuck in the palace materials, and he has not yet taken into account the particularity of marine materials.

Although Zhu Youzhen is not proficient in marine materials, he still knows a little general common sense.

The boat is soaked in water. This is destined to be a much stricter choice of marine materials than other buildings.

Marine timber is a primary concern for decay in humid environments.

Zhu Youxiao just ignored this point, and was greatly ridiculed by Zhu Youzhen.

In the face of Zhu Youxiao, Zhu Youjian can only have a slight upper hand in materials now. In other respects, in the face of the genius carpenter emperor, he is not an opponent at all.

The sky was dark, and Zhu Youzhen returned to Ciqing Hall tiredly. It's too late, it's not very convenient to get out of the palace, let's stay here.

Well, I'll admit that the main thing is that I'm too tired and don't want to move anymore at all. Lying on the bed, Zhu Youzhen thought silently.

Big Brother Carpenter is terrifying, he's just a technical controller, no, a technical maniac. It's too tiring to argue with him.

However, after discussing with Zhu Youxiao, Zhu Youzhen felt that he still learned a lot of assembly skills for large-scale models. The assembly speed of future models will definitely be greatly improved.

It's not in vain.

No, in order to maintain his little self-esteem, he won't be destroyed too much by his big brother. Zhu Youzhen came to this era and took the initiative to learn for the first time.

"Oh my God?" For the first time in more than a year, Zhu Youzhen did not call his naval auxiliary system for the purpose of redeeming.

"God is there for you." The system God still responded to the call without hurry.

"I want to systematically learn the various basic materials required by the ship, is there a way?" Zhu Youzhen asked a little apprehensively.

"Yes." God replied crisply.

"You can authorize the teaching mode to be turned on. In this mode, you can study the basic discipline of the Navy, materials science. God added.

"It's that simple?" Zhu Youzhen asked in disbelief, "Just need to authorize the opening of the teaching mode?" ”

"Yes." God still answered simply.

"......", Zhu Youzhen thought for a long time and didn't find anything that violated common sense.

Ruthless, Zhu Youzhen gritted his teeth and said: "Authorize God to open the teaching mode." ”

"Yes." God simply agreed, and there was no sound.

In this regard, Zhu Youzhen has experience, which is a necessary situation for the system to load new modules. For some reason, Zhu Youzhen always felt a little chill in the back of his head.

Without waiting for the system to be updated, Zhu Youzhen fell asleep.

It was late at night, and the tired Zhu Youzhen dreamed for the first time in two years.

He had a beautiful dream.

In his dream, he was standing on an aircraft carrier, with planes flying overhead, and the Ming Sun and Moon Flag planted on every continent in the world. The official language of the world is Chinese.

What the hell is English? Let's play while we go.

Fanbang foreigners, welcome to take the Chinese language test level 9.

Zhu Youzhen, who was asleep, showed a sweet smile.

The sun was shining all over the Ciqing Palace, and Zhu Youzhen was lazy and didn't want to get up. It's so good to wake up naturally from sleep, especially when you dream and wake up naturally.

In a state of dreaming, the attraction of the bed becomes so great!

Thinking of last night's dream, Zhu Youzhen still forced himself to get up. You must be diligent, otherwise the dream will not come true, and the nightmare will wait for you in the near future.

Patting his cheek, Zhu Youzhen cheered himself up: "Come on, young man." If you want to sleep lazy, let's wait for the Manchu Qing to be swept away. ”

"Wang mix, find the best gem craftsman for Lone, and then find some large pieces of transparent crystal for Lone."

As soon as he replied to the palace, Zhu Youzhen shouted loudly, since the telescope is a voyeur artifact, since he thinks of it, he must do it immediately. Voyeur artifact!

In this era when there is no colorless glass, natural crystals can only be used to polish telescope lenses. This requires a skilled lapidary to do well.

Gem craftsmen and crystals, Wang Chengen soon delivered.

"Do you have a problem grinding it in this shape?" Zhu Youzhen drew the shape of a convex lens on paper and showed it to the lapidary.

"What is only needed is this kind of lens that is thick in the middle and thin around the perimeter, and it should be excessively uniform, and there should not be any uneven thickness." Zhu Youzhen repeatedly emphasized.

"Don't worry, the villain will never make a mistake." The lapidary is an old man in his 50s, an old craftsman who has been working on gemstone polishing and setting all his life, and he does not pay attention to this little work at all.

Zhu Youzhen, who was not at ease, couldn't help but advise again: "You must ensure that the center is the thickest." ”

"Don't worry, if there is a mistake, you can play the villain's board." The old craftsman was angered by Zhu Youzhen's repeated admonitions, and his speech became hard.

"Hehe, if the master can satisfy Lone, Lone will not hesitate to reward him." Zhu Youzhen added embarrassedly. For the rest, he can only hope for the craftsmanship of the old craftsman.

Still have to find a place to make glass, Zhu Youzhen secretly decided.

Glass was called glaze in ancient China, and it belonged to the decorative category. For a long time, glaze was strongly suppressed by porcelain because of its low cost performance, and it was only a niche commodity in ancient China.

Whether it's glass or glass, Zhu Youzhen really can't make it. However, Zhu Youzhen is not worried. The history of the existence of glass in China is not short, but it has not made efforts to universal application.

I believe that it should be no problem to find a craftsman who makes glass. For Zhu Youzhen, as long as there is a technology to make glass, it is easier to improve the application than to invent.

However, if the glass can't be found for a while, it will have to rely on the crystal for emergency.

"Well, the crystals themselves are also valuable, and they are worth looking for."

In his previous life, Zhu Youzhen had heard of the land of glass and the land of crystal.

Isn't glass the predecessor of glass?

In the previous life, the hometown of glass was in the impression of Zibo, Shandong, right?

The hometown of crystals is probably Lianyungang, Jiangsu, right?

Where these places are in the Ming Dynasty now, Zhu Youzhen is not clear.

Check the map, right?

Looking at the most detailed map of Daming in his hand, Zhu Youzhen shook his head helplessly. In this day and age, even maps are blurry. It's really like traditional Chinese philosophy, where everything is chaotic and ambiguous.

The most detailed map in Zhu Youzhen's hand only has simple landscapes and administrative divisions, and the proportions of the map seem to be a little out of balance.

"This kind of freehand map can also command a war?" Zhu Youzhen expressed strong doubts. "No wonder the Ming army can't defeat Houjin."

Civilian commanders would never have been on the front line in person, directing battles according to such a map? Dizzy, is there still a reason for this to lose?
