Powerful Song Dynasty

Chapter 1131 Looking Glass

"That's natural. The two lenses are flat, so there's nothing novel about it." Li Changsheng was already shaking with laughter, full of self-entertaining humor.

Feng Yuan's face was already flushed, and he glared at Li Changsheng fiercely. This guy obviously saw that he was making a fool of himself, and even led him into a misunderstanding, and he was not a son of man.

Lin Silang hurriedly picked up a lens on the table, handed it over and said, "Fourth brother, this is a convex lens, it is used with a telescope, it can see farther and bigger."

Feng Yuan took it and looked at it suspiciously, then looked at Li Changsheng who was smiling, and looked at it hesitantly.I don’t know if I don’t look at it. I was startled when I saw it. The whole mirror came into my eyes. It was Li Changsheng’s big bloody mouth, and the two rows of big white teeth opened and closed right in front of his eyes, which really scared him. Jump.

He hurriedly put down the lens, and hurriedly said: "This is... oh, this is a convex mirror. Could it be that you use the principle of concave and convex mirrors to magnify?"

Since he followed Wang Xiu, he naturally knew physics, not to mention the not-too-advanced principles of optics, so he knew better what the appearance of this thing meant.

"Exactly." Zhang Ling said with a smile, that fat face is full of pride, don't underestimate the mere lenses, the knowledge in them is huge, just the focal length and the quality of the lenses cost them a lot of energy .

"Third brother's mouth can hold a bucket of rice." Now that Feng Yuan understood, he joked.

The brothers laughed again, and Zhao Feixiao burst into tears, and hurriedly said: "If the third brother can't eat a bucket of rice, how can he win the champion of martial arts?"

"I have to add a sheep." Zhang Ling made a joke on a rare occasion, but he still had a serious face. Coupled with that chubby image, it really made people laugh.

Li Changsheng rolled his eyes and said, "You also ate a bucket of rice and swallowed a sheep, and see if you can get the number one scholar."

"If I want to be able to do that, I would have already become a marshal." Zhao Fei laughed.

Feng Yuan rolled his eyes, how can he be so easy to be a marshal?Liu Guangshi just happened by chance, relying on his seniority and the balance of the court, he became a privy secretary and joined the army.

"This thing is good. The vast sea stretches as far as the eye can see. Soldiers hold this thing on the mast and look far away. They can detect movement dozens of miles away, and we can preemptively strike." Li Changsheng said confidently, this thing is a good thing!

The guard water army has thousands of warships. Looking at the whole world, there is no power to contend with it. There are only a few countries in Shendu, West Java, and Dashi, who can confront the expedition fleet of the Song Dynasty, and can detect the enemy in advance. Naval battles have wonderful boosts.

I think that before the enemy finds you, you can plan against the enemy and make deployments that are beneficial to your own side, which is of great significance in naval battles.Because, whether it is the current or the wind direction, it is extremely difficult for the sea comrades to have a certain combat mode, change the formation or temporarily turn.The benefits of preemptive strikes are self-evident.

"Have you developed it to the final level?" Feng Yuan was more pragmatic, grasping the core of the problem in an instant.

"Although it is not perfect, it is already practical, but the processing of the lens is very difficult." Zhao Fei said indifferently, he presided over the development, so he naturally has the right to speak.

"Oh, tell me in detail." Feng Yuan became curious.

"We named it a telescope, which is made of glass." Zhao Fei looked a little excited, and said loudly: "The front mirror of the telescope is thick and long, and the lens behind the telescope is thin and short. The front mirror comes from a distance The light of the scene converges into an inverted and reduced real image, which is equivalent to moving the distant scene closer to the imaging place. The inverted image of the scene happens to fall on the front focus of the eyepiece. It seems to be magnified, and the distant scenery seems to be close to the eyes. However, judging from the current quality, the craftsmanship is not satisfactory, and it is barely usable."

"I'm ashamed to say that glass production is not easy, and the convex-concave mirror technology requirements are quite high. There is no room for mistakes, and all defects will be spent."

Li Changsheng frowned, and said with a faint smile: "If you can improve the quality of glass and form a large-scale production, you can make a lot of money."

Feng Yuan glanced at Li Changsheng, said with a smirk: "Third brother has been away for a few years, but he has learned a lot about business management."

"We were also forced to rely on ourselves for everything. We can't be like you. We just need to concentrate on fighting. Everything is provided by the imperial court. We are very miserable." Li Changsheng said very playfully, but revealed a deep sense of helplessness.

Feng Yuan nodded silently. He was the one who led the army and knew the hardships of wartime. Even if there were sufficient logistics supplies, defeating the opponent was not an easy task.

The expeditionary fleet of the bodyguard water army is fighting alone in a foreign land. It is impossible to do whatever you want with manpower and materials. Everyone is precious. Every piece of armor must be carefully maintained. Every battle must be carefully calculated. It is ten times harder for him to be self-reliant and support the war by fighting, which makes it impossible to refute.

Zhang Ling didn't have the concept of Feng Yuan, and said to himself: "This is true, the king of Hangzhou, Yan Chou, came because of his diligence."

"Oh, it seems that the Hangzhou Pangzong is interested?" Li Changsheng, as Wang Xiu's disciple, naturally attributed himself to the Wang family.

Zhao Fei smiled disdainfully, the branches of the Wang family in Hangzhou and Wenzhou are really good at business.Just a few years ago, the Yuquanshan Research Institute launched an improved glass, which is still translucent, adding various metals to create various colored glasses.The two offshoot family heads came to the door immediately, and got the production rights without any suspense, and the Shi family was defeated.

That was a huge amount of income, enough to make people murder with envy. For this reason, the Shi family was still indignant, and there were rumors that the king's business was for the benefit of the public.

Of course, the research institute and those people also received considerable fees, and the money belonging to the research institute was invested in glass improvement.

The reason for rushing to the line is that the body frame of the telescope is made by Zhongshan Academy, which is also close to the major yamen of the Imperial Army, so it is convenient for testing.

Li Changsheng didn't care. Whoever gets it doesn't matter. This is not what he cares about. Whether it can be produced in large quantities is the most important thing. He calmly said: "These are side details. When will I get this thing out?"

Zhao Fei glanced at Li Changsheng contemptuously, and said in a long voice, "It still takes a lot of work, I can't eat hot tofu in a hurry, third brother, don't be impatient."

"By the way, the telescope is also suitable for the Ma Bujun." Lin Silang said.

"If you don't say it, you'll forget it. When the Tianwu army comes back, I don't know where the fourth brother is going. Should he return to Shushu or Liudianqian?" Zhao Fei said suddenly.

"Maybe I will resign, I don't know where I will go." Feng Yuan replied honestly, with some reluctance.
