After Li Yuanba left, only Wu Shun and the little maid Yingxiang were left in the middle courtyard.

Seeing that her young lady was still looking like she was frowning, Xiao Yingxiang suddenly became a little puzzled and asked, "Miss, what's wrong with you, are you still worried about the prince?" ”

Wu Shun bowed slightly, and said: "Although the husband is said to be a prince, but this qiē is given by His Majesty, if the prince is bewitched by Nada Suge and wants to make ......"

"Make what? Miss, does that Tibetan minister want to harm the prince? The little maid asked with some panic.

"With the wisdom of the husband, I will definitely not be bewitched by Dasug, I am just worried that someone will go to your majesty to stab the knife, even if your majesty will not really blame the husband, but after all, it will cause a burst of reprimand, which is always inappropriate!"

Wu Shun stared at the sky, and the worry in his voice could not be concealed.

……

Shenji House, Ministry of Industry.

Accompanied by the director of the Ministry of Industry, Li Yuanba visited the internal facilities of the Ministry of Industry.

"Mansion Master, what drawings did you leave before, in addition to the powerful firearms, there are many exquisite things, during this period of time, not only has there been a breakthrough in the development of firearms, but even those exquisite things have also made progress!"

The man who spoke was a middle-aged man who looked to be in his forties, with strange curly hair, dressed in a dark red robe, and his figure was not strong, but there was an indescribable momentum in his body.

This guy's name is Lu Zhengming, it is said that he is a descendant of Lu Ban, and he has a very high attainment in process design and manufacturing, so he is also the director of the Ministry of Industry.

"Lord Wang, the thing you designed is simply amazing, just a small tube, just two thin so-called lenses, you can see so far, and it is so clear, amazing. It's amazing! ”

At the mention of one of these things, Lu Zhengming's face flushed with excitement, as if he had given birth to a child himself.

Li Yuanba was slightly stunned when he heard this, and said, "Lens, a small tube?" ”

"yes!" Lu Zhengming nodded, and at the same time said while gesturing with both hands: "It's one section at a time, you can zoom it, and then put two small lenses on it, and you can adjust the distance one by one!" ”

"Damn, isn't that a monocular?"

Li Yuanba figured it out. The emotional telescope has been developed, you know, the lens of the telescope is the key, I didn't expect them to break through this difficulty, it's really incredible.

"Quick, take a look at this king!" Li Yuanba was too lazy to be hypocritical, and directly begged Lu Zhengming for it.

"Wait a minute, Lord Wang!" Lu Zhengming answered, called a small servant, and ordered him to hold his warrant. Go to the warehouse and pick up a few of those delicate knick-knacks.

After the time when there was no tea, the little guy came back with a small tray.

"Lord Wang, please look!" Lu Zhengming handed the tray to Li Yuanba with some pride, and asked him to take a closer look.

I saw two things in the tray, both of which looked quite novel. One is something like a thin bamboo pole, except the length of the fist, but it looks like it can be scaled; As for the second one, it's a crystal thing.

Pinch the one that looks like a clear crystal. Li Yuanba knocked lightly and said, "Glass? ”

"Exactly!" Lu Zhengming said a little proudly: "Lord Wang, since you left the method of making this glass. Our Ministry of Industry sent a special person to study day and night, and finally made a breakthrough in the first two days, although the glass making technology is not yet mature, but like this kind of glass, it can still be mass-produced! ”

Glass, which is formed by the melting of sand and other chemicals, is mainly produced from soda ash, limestone and quartz.

In the smelting method left by Li Yuanba, it was not written so clearly, after all, he was a liberal arts student, and he was born with a science dementia, so he could only point out a general method to the people of the Shenji Mansion, but fortunately, there were too many skilled craftsmen in the Shenji Mansion, and after all, they were allowed to develop the glass.

"Good! All right! ”

Feeling the touch of some unevenness on the glass in his hand, Li Yuanba said with emotion: "You do your best to perfect the method of making glass, and when this thing can be mass-produced, this king will ask Your Majesty for credit!" ”

No one knows the importance of glass better than Li Yuanba, this thing was a household name in his previous life, and everyone must have it!

"Lord Wang, look at this again!" Lu Zhengming didn't answer Li Yuanba's words, and directly picked up the bamboo tube that was only the size of a fist.

Li Yuanba understood what was going on as soon as he saw this thing, isn't this a telescope?

Stretched out his hand to take the bamboo tube, but he didn't expect it to sink into his hand, it turned out to be metal, but it was painted with a layer of paint like a yellow bamboo pole on the outside.

"Iron? It's kind of interesting! ”

Li Yuanba muttered to himself, gently unscrewed the lens on the front of the bamboo tube, and then threw it down slightly, 'brushed' the ground, and three bamboo tubes appeared in front of Li Yuanba.

"It's quite cleverly designed!"

Li Yuanba lifted the four monoculars and put them in front of him, and suddenly a hundred feet away.

Twist the lens back for a section, and 100 zhang becomes 75 zhang, and then twist it back, and the distance immediately shrinks from 75 zhang to 50 zhang...... And so he went back and forth, until by the last quarter there were only twenty-five feet left.

Although this thing is not as good as the high-powered telescope in Li Yuanba's previous life, this distance of nearly a hundred battles has an incredible effect on wartime.

"Not bad, not bad!" Li Yuanba put down the monocular in his hand, patted Lu Zhengming's shoulder, and said, "Can this thing be made in large quantities?" ”

Lu Zhengming, who was still full of arrogance before, heard Li Yuanba's words, but his face collapsed in an instant.

Seeing Lu Zhengming's face-changing stunt, Li Yuanba was stunned and said, "What? Can't it be mass-produced? Haven't you already cracked the lens problem above? Isn't it okay to use glass? ”

"In fact...... Not really! ”

Lu Zhengming shook his head with a dejected face, and said: "The lens used in this monocular is made of transparent crystal, which is repeatedly tried and carved, and transparent crystals are rare even in our Datang. In order to make this monocular, at least one-third of the transparent crystal in the secret store of the Divine Machine Mansion has been used! ”

Li Yuanba's eyes widened suddenly, he pointed to the monocular in his hand incredulously, and said, "You mean to say that the remaining transparent crystals in the secret vault can only make two more telescopes?" ”

"No, no!"

Lu Zhengming hurriedly waved his hand and said: "Actually, after making the lens on this telescope, our technology is already very mature, and the remaining transparent crystal can still make ten monoculars!" ”

"Good! Ten is enough for the time being! Li Yuanba nodded and said, "It's still the same sentence, you continue to make glass at night, and after you have achieved something, Your Majesty will lower the reward!" ”

"Thank you, Lord Wang!"

In fact, for these scientific research maniacs, it doesn't matter whether they are rewarded or not, the important thing is to keep studying those interesting things, which is more important than their lives.

"Okay, this monocular will be taken away first! By the way, you'll take me to the storehouse later, and I don't know if any new firearms have been developed recently! Li Yuanba put away the monoculars and walked outside the Ministry of Industry.

Just after leaving the gate of the Ministry of Industry, Li Yuanba bumped into the burly black gold.

"Black Elder?" Li Yuanba said in surprise.

"Oh, lord!"

Hei Jin saw that Li Yuanba was obviously flustered, but then there was ecstasy, he didn't say a word, he picked up Li Yuanba, and was about to walk to his small courtyard in the southeast of Shenji Mansion.

"Alas, I said Hei Lao, what are you doing?" Lu Zhengming chased closely behind Heijin, trying to hold Li Yuanba.

"Xiao Lu, come over if you want! By the way, bring those little apprentices of Lao Tzu! "The black gold in front of him is running like flying, and with Lu Zhengming's small speed, he can't catch up with it.

Li Yuanba turned his head and glanced at Lu Zhengming, who was running closely behind him, and said to Hei Jin, who was walking like a fly in front of him: "I said, Hei Lao, what are you doing here?" ”

Hei Jin said with an anxious face: "Lord Wang, didn't you ask Lao Hei to build a monument to the soldiers who died before, and design all the surrounding houses and buildings?" Lao Hei worked day and night to paint during this time, and the painting was finally completed this morning. I was going to ask the little babies from the Ministry of Work to help Lao Hei take a look, but I didn't expect to meet the prince. Just right, please go to my little courtyard to see if there is anything missing. ”

"Oh? Finished the blueprints so quickly? ”

Li Yuanba couldn't help but snort, this old man is quite efficient, but our master is the supervisor of this matter, so he naturally wants to check it out.

……

"Lord Wang, please come in!"

ran the entire Shenji Mansion, and finally came to Heijin's small courtyard, Heijin politely pushed open the door and invited Li Yuanba into the courtyard.

Not to mention, there are really a lot of people in the small courtyard of Heijin, or old men with white hair, or people with white temples who are not confused, and there are more young people who are sturdy and energetic.

Looking at their appearance, they are rushing back and forth between these square inches, and they all seem to be very busy.

"Lord Wang, these little babies are either Lao Hei's apprentices or Lao Hei's apprentices, they are all here to help Lao Hei!" Heijin led the way, walked to a large and long scroll, and said, "Lord Wang, please see, this is the monument and the architectural drawings around the monument......"

Hei Jin's face was full of pride, and it could be seen that he was very confident in his design drawings.

"Well, let's take a look at this king first!"

Li Yuanba nodded, took a few steps forward directly, and looked at the long design of this pair carefully. (To be continued......)
