After Cao Sanxi, Cao Huachun, Wei Zhongxian and others who were responsible for Zhuangzi's economic operation retired, Zhu Youdong sent someone to invite Xu Guangqi in.

Apart from Zhu Youdong, no one can control the overall situation of Honghe Village. Those in charge of operations cannot control technology, and those in charge of technology cannot control security. And Li Shizhong cannot intervene in anything except security.

"Mr. Xu, let's get started? Which masters should we invite in first?"

"Your Highness is pressed for time. He will have to return to Xinghua Palace later to prepare for tomorrow's homework, so I think it is better to do the difficult things first and then the easy ones."

"Okay, let's invite Master Huang and Master Huo to come in first."

Huang and Huo are the leaders from the porcelain group and the iron group, and they have the heaviest tasks.

"Master Huang, tell me about the situation here."

"Yes, Your Highness, Mr. Xu. In the past year, the little old man has mainly followed His Highness's instructions to make bone china. Due to the use of thermometers, we can now more effectively control the heat after opening the furnace. We have developed a

I made various types of porcelain containing 25%, 30%, and 40% bone powder. I also fully mastered all kinds of coloring. But, uh... Your Highness, I live very comfortably in Honghe Villa, and my family is also very satisfied.

, I have absolutely no intention of leaving. It’s just that there are very few clay sources near the capital, and the quality is still very poor. In addition, our Zhuangzi’s bone meal is mainly based on pig bones... Therefore, although this bone china is not easy to break

It has many advantages, but it is still a little short of completely surpassing the top quality porcelain in Jingdezhen.”

"Hehehe, Master Huang still sticks to his profession. Well, as for this bone china, it's enough to achieve this level. What I'm interested in is, how is the development of this glass?"

"Reporting back to Your Highness, according to the three methods of heat preservation taught by Mr. Xu (actually several methods of physical heat transfer in junior high school), the young man and several masters rebuilt the crucible kiln. This temperature can be guaranteed, quartz, soda ash and so on.

It can also melt. The little old man also ordered the strong young man in the village to stir continuously (to release bubbles). But the fired glass still feels not completely transparent."

"Has Mr. Xu gone to see it?"

"I have visited many times. The masters are really working hard. However, the fired glass always feels slightly reddish, and after it is shaped into a flat plate, there are obviously some impurities inside, and it is also very brittle.

It broke accidentally."

"Reddish? Oops, why did you forget this section?" Zhu Youdong patted his head: "Mr. Xu, Master Huang. This should be because other metal impurities in the minerals have not been removed."

"Your Highness is wise!" When Xu Guangqi heard this, he jumped up: "I actually think this is the case recently. Well, Master Huang, do you know what to do next?"

"Don't worry, Mr. Xu, I'll leave this matter to the little old man." After saying this, Old Man Huang turned around and left. Finally, after walking a few steps, he suddenly remembered and turned around quickly: "Your Highness, forgive me! Little old man...

...Young people, I’m so rude.”

"Hahaha, it doesn't matter, Master Huang, go quickly." As a time traveler, when facing technical workers, he likes this kind of technical nerd. The kind of guy who thinks too much about things other than technology in his head, he

I don't feel confident using it.

Oh, glass, as long as large pieces of flat glass can be produced stably, I can use silver to make mirrors! That is a real money-making tool!

Zhu Youdong was in such a good mood that he couldn't help but laugh out loud. When Huo, the leader of the blacksmith team behind him, came in and saw Zhu Youdong's silly look, he couldn't help but wonder: With such a silly look, he was probably mentally retarded, right?

"Haha, this is Master Huo, right? Come on, sit down. Master Huang just solved a production problem, so he got a little carried away. Master Huo, how are you doing during this period? Your family and children are doing well.

Bar?"

"Thanks to His Highness, everything is very good. I have nothing to be dissatisfied with. I just feel that our group has brought out too little, and I may be unworthy of Your Highness's kindness!"

"Well, tell me, what has your iron group produced recently?"

"Reporting to Your Highness, for the past six months, we have been grinding this screw every day according to the weights and measures set by Your Highness. After seven or eight months, we have only polished three screws." Seeing that Xu Guangqi next to him didn't look very good, Lao Huo hurriedly

Continuing: "Your Highness, Mr. Xu, I have not been lazy at all in the past few months. The worn screw is worth three hundred if not five hundred."

"Huh? Master Huo, those three screws, do you think they are successful?"

"Yes, Your Highness. I am ashamed that I received such a great favor from His Highness, and only got three of them..."

"Bring them to me to see."

"The three small screws have all been brought... Your Highness, please see, this one is centimeter-level, and the spacing between each thread is one centimeter. This one is five millimeter-level, and the spacing between each thread is

It is five millimeters. For these two screws, we have ground nine threads. It can indeed ensure that the spacing between each thread is exactly the same. The last one is millimeter-level, but the villain waits for time and

My skills are limited and I can only grind out three threads..."

"Okay! Okay! Okay! Master Huo, all the masters in your group have worked hard!" Standing up, Zhu Youdong instinctively wanted to pat Lao Huo's shoulder, but after stretching out his hand, he remembered that his body was still weak at the moment.

Less than six years old.

Withdrawing his hand in embarrassment, Zhu Youdong said to Xu Guangqi: "Mr. Xu, these masters have done a great job! I will give them a heavy reward!"

"I don't quite understand what Your Highness means."

Speaking of which, Xu Guangqi's current job is to be a concubine of the Hanlin Academy. This is a relatively leisurely official position that focuses on observing political affairs. After being invited to teach under Zhu Youdong, the engineering man spent more time in Honghe Village.

.

Over the past six months, the craftsmen arranged by Zhu Youdong, under the unified command of Xu Guangqi, have been working on various topics designated by Zhu Youdong. Speaking of which, the blacksmith group cost the most, but achieved the least results. Unexpectedly, it was already making money for Honghe Village.

The porcelain group did not get the praise, but the blacksmith group who was not optimistic about it got it?

He was confused, but Zhu Youdong was happy: "Master Huo, the nine-grain screw is enough. With nine-grain, eighteen-grain, twenty-seven-grain... Once you have the mold, you can have as many grains as you want.

Mr. Xu, don’t underestimate this screw. With the screw, there are fixings, actuators, and future rifling!"

"What His Highness said, I seem to have touched something, but it's not very clear yet."

"Hehehe, well, you will know the wonderful use of the screws after they take out the actual objects. Master Huo, you will go to Master Huang later and ask them to bake molds for you and make more copies of this set of screws.

.And I have a few sets of drawings here. After you take a look at them, you will naturally know what the screw can be used for!"

"Yes, I would like to thank Your Highness for your generosity. I will continue to work hard and come up with something practical to repay Your Highness as soon as possible."

"These three screws are amazing things. The huge reward I just mentioned is really not a joke."

The research and development of the porcelain group and iron group is considered the heaviest at this stage. The cloth group, carpenter group, and leatherwork group are relatively easy.

After many repeated trials, the fabric team has come up with what Zhu Youdong needs: denim. It is very wear-resistant and relatively soft. This kind of fabric is not only used as a soldier's coat, but also as a canvas.

.

During this period, the carpenter team has built various molds according to Zhu Youdong's drawings. As a non-engineering time traveler, many of the sketches made by Zhu Youdong are actually full of errors. However, in line with the principle that "practice is the only criterion for testing truth"

In principle, Zhu Youdong also asked them to use various molds to make various things in the next time.

In fact, the biggest contribution of the carpenter team during this period was the creation of all kinds of strange water conservancy machinery. Now, not to mention the land along the river, the entire village of Honghe Village is irrigated by river water. The work in the workshop originally required a lot of manpower.

, have also begun to be replaced by machinery. The only problem is that although carpenters are extremely capable and intelligent. However, no matter how precise the mortise and tenon structure is, it is still difficult to last under the action of long-term and huge stress - and

This will be solved quickly with the advent of screws.

During this time, the cobbler team produced a variety of leather boots, leather jackets, leather jackets and other items. These items will become the basic equipment of the Ming army soldiers in the future. Some of them are fine leather jackets made according to the shapes of Zhu Youdong and later generations of clothing.

Leather boots, leather bags, etc. are high-end goods that he gives away.

(Sailboats in ancient China were all hard sails. Of course, hard sails are extremely adaptable to the sea conditions of the South China Sea, and the wind-receiving area is larger. In fact, after the Portuguese settled in Macau, in order to better adapt to the conditions of the South China Sea,

The wind direction and speed changed all the soft sails to hard sails. But after the time traveler took charge of the Ming Dynasty, if China was to enter the era of large-scale navigation, the high-mast system would be necessary. At that time, large-area soft sails would still be
