Great Tang princess

Chapter 618 Inspiration for a New Invention
The success of the greenhouse experiment was a gratifying event. Li Yuechen took a photo on the day of harvesting the vegetables, and sent it back to his mother along with a letter, telling her the good news.

Immediately afterwards, he gave an order to the Academy of Engineering and began to study the incubator.

After the Academy of Engineering received the order, it immediately took action without saying a word.

"Your Highness, how to determine the size of this incubator?"

In the farm, a group of craftsmen surrounded Li Yuechen, discussing the size issue.

Everyone was in an empty room that had been vacated, observing the interior space of the room, thinking about how to place it.

Li Yuechen thought for a while: "The incubator should be able to be made layer by layer, just as high as this palace. As for the size, each layer must be able to hold at least a hundred eggs..."

As she spoke, she walked to the corner of the room, raised her hand and gestured: "A box should be placed here first, leaving a space for passage in the middle, and then..."

After listening to her explanation, a craftsman walked to the wall, pulled out a tape measure, measured the distance, and then said, "There should be some distance between the incubator and the wall, so six hundred and five is about the same?"

Ever since Li Yuechen brought the tape measure over after the year, these craftsmen have fallen in love with this thing thoroughly. The craftsmen assigned to it keep holding it with them every day, and take it out to have a look if they have nothing to do.

Now Dongdu is still producing continuously, because the female ruler is there, so the production of the tape measure is handed over to Dongdu, and then it is sent over continuously.

Although they have been taught various units of length, these craftsmen still don't like to say a few meters or a few centimeters, but prefer to use millimeters as the main unit.

The six hundred and five he mentioned just now means 650 millimeters.

Another craftsman shook his head: "For this matter, it's better to go back and take a hundred eggs to measure the specific data. Your Highness once said, don't waste it. We should try to use every inch of space as much as possible."

Li Yuechen really wanted to remind him that when he said not to waste food, he was referring to food, but it is a good thing to have this kind of craftsman spirit of excellence, so he didn't say anything, but nodded appreciatively.

……

Two days later, the reply from the palace came.

Wu Zetian reserved opinions on the system reform proposed by her daughter, and believed that the reform should not be too fast, and it would not be too late to act when the time came.

Later, he expressed his appreciation for the off-season vegetable and fruit experiment in the greenhouse, and decided to promote it in the Royal Farm to increase the supply of some winter vegetables and fruits.

Li Yuechen has no objection to this, and can open another vegetable and fruit shop at that time.

Now, as a princess, she has been involved in quite a few industries, and it's not too late to open such a shop.

Then Geng Yunqiang and other officers were called to discuss the issue of establishing military divisions in Weihai and Dalian.

In the princess' office, Xiaodong made a cup of tea for no one, and lit some incense beside them, so that they could talk about things at ease.

"Okay, this is probably what I think. If you have any opinions, let's talk about it together." Li Yuechen put down his teacup, leaned on the back of the chair, put his left leg on his right, and waited for their opinions.

Everyone looked at each other, and Geng Yunqiang was the first to speak: "Your Highness, these two places are no-man's land. If you want to build a military camp here, you need a lot of people."

This is true. Both Weihai and Dalian are now barren lands that need to be developed from scratch.

Wang Wuqiong next to him had a different opinion: "This subordinate thinks that it is a trivial matter to need manpower, after all, there are quite a few captives here..."

Many things happened in the past few years, and many prisoners were captured. These people are currently in the barracks. Some of them have received a high degree of ideological education and performed well. They have been selected into the logistics force and become formal engineers.The rest are still captives, working as usual without getting paid.

"No, manpower is a big problem. Don't forget that it was originally planned to carry out the telegraph project between Dongdu and Chang'an this year. This will definitely consume a lot of manpower." Geng Yunqiang reminded.

Last year, it was decided to lay telegraphs this year to completely connect Chang'an and Dongdu, so that instant communication between the two places will be possible in the future.

However, Li Yuechen raised his hand at this time: "No, let the Qianniuwei engineers and soldiers do the telegraph project! This is an important weapon of the country, and it must be done by our own internal staff. It is good to send someone from the Engineering Academy to supervise it. Those captives will develop these two places. , what do you think?"

For now, Li Yuechen doesn't want to let outsiders know about the telegraph technology, so this project is going to be done by the army.

"If this is the case, there is no problem in terms of manpower. But Your Highness, how to solve this connection problem?" Geng Yunqiang asked.

An officer next to him asked back: "Isn't there a hang glider?"

"How can it be that simple?" Wang Wuqiong interrupted the other party's words, "The training conditions for pilots are extremely strict, not only the requirements for eyesight are extremely high, but the physical fitness must also meet the standards. people."

Li Yuechen picked up the teacup: "Well, it seems that there is a problem. There needs to be a way to communicate with the three military camps. The message transmission can't be too slow..."

Everyone else nodded, the current problem is still here.

At this time, everyone discovered a problem. Today's army needs to ensure the speed of information transmission, and creatures like horses can no longer keep up with their needs.

Now they all began to instinctively think about problems at a higher level, and no one said anything like riding a horse to deliver a message.

At this time, the officer who had just spoken spoke again: "If you can't fly, how about in the sea?"

"Huh? What do you mean?" Geng Yunqiang said he didn't understand.

The other party replied: "Your Highness can step on a wooden plank and fly across the sea, and the speed is not slow. Can't you use this to pass the news?"

Li Yuechen smiled, and then waved his hand: "You mean surfing? No, the prerequisite is that there must be waves, which is essentially a game... eh? Wait!"

She slapped her head suddenly: "That's right! Why did you forget this..."

No surfboard, you can use windsurfing!
This thing is also simple to say, that is, a sail is added to the surfboard, just like a sailboat, it can glide on the sea with the help of wind, without the need for additional assistance from waves.

Even on a relatively flat sea, it can be driven as long as there is wind.

The speed of this thing is not slow, and the speed can even be more than seventy or eighty per hour.

It doesn’t matter if the seaside freezes in winter, if you install a skate under the board, you can still slide on the ice, and the speed can exceed [-] kilometers per hour!
It's just that whether this thing can be made in this era, I'm afraid we need to do an experiment, but it shouldn't be a big problem. Since the bearing can be made, the most important part of the sailboard should be able to be done.

"Okay, let's go back today, and wait for the results of the experiment to come out in a few days." After speaking, Li Yuechen got up and left, and took Xiaodong to the Engineering Institute.

There is the most important accessory on the sailboard, the universal joint.

As long as this thing can be made, windsurfing can be done, so Li Yuechen plans to let the craftsmen of the Engineering Academy try it first.

Seeing that the princess left just like that, everyone in the office looked at each other in blank dismay, saying that they were here to discuss something, why did they leave without saying a word?
Wang Wuqiong suddenly smiled: "Your Highness is extremely intelligent, I think he has thought of a solution..."

"Well," Geng Yunqiang nodded, "With His Highness's ability, it is estimated that some kind of magical object will be made again."

……

On the other side, Li Yuechen, who came to the Engineering Academy, called all the craftsmen over: "Listen up, there is a very challenging project next, universal joint! Paper and pen!"

The apprentice on the side quickly brought a blank paper and pencil over.

For so many years, every time Li Yuechen made new things, because he couldn't speak clearly, he often had to explain to them while drawing pictures, so the engineering academy also kept pens, ink, paper and inkstones at all times.

But now there is no need for a brush, and Li Yuechen is more used to drawing with a pencil, and it is easier to draw.

"There is a cross shaft in the middle of this object, so it can rotate in multiple directions. Try the material yourself, but in terms of effect..."

While drawing pictures, Li Yuechen talked about the effect she needed to achieve. Although many of the things she said made the apprentices next to her a little confused, but the group of craftsmen who had worked with her for many years understood them all.

"Your Highness, this thing is the same as the bearing, it needs high-precision grinding, and I'm afraid it will be difficult to complete it in a short time..."

This answer did not exceed Li Yuechen's expectations. This thing seems to be quite simple, but in this age when all parts are rubbed by hand, it is indeed very troublesome.

"how long will it takes?"

Wang Gangdan thought for a while: "According to the experience of my subordinates, it should take about ten days."

"Okay, let's try it first, don't worry too much."

Li Yuechen didn't want to put pressure on them either, as long as he was willing to try hard, that's enough, even if he couldn't do it, it would be a big deal to think of other ways.

After confirming that there was nothing wrong with them, Li Yuechen turned around and left. Before leaving, he didn't forget to promise that there would be a reward for making them, so as to mobilize their enthusiasm.

……

Leaving the Academy of Engineering, I happened to see Wang Wuqiong coming over.

"Yo, have they all gone back?"

"Your Highness just left directly, so I will leave first, does Your Highness have other orders?" Wang Wuqiong asked.

Li Yuechen waved his hand: "No, the key still depends on whether this thing can be made."

The two chatted while walking, and after talking about work topics, Li Yuechen couldn't help but gossip.

"You and Nadou Lu Yuanzhong, is the matter settled?"

"It's decided, just choose a suitable date to get married after I go back." Wang Wuqiong nodded and replied, "Also, he also promised me that I can continue to serve as His Royal Highness's guard after marriage."

However, Li Yuechen shook his head: "Forget it as a guard, you, it's better to work in Qianniuwei or the Ministry of War after marriage."

"Dare to ask Your Highness, why is this?" Wang Wuqiong was a little puzzled.

"Warriors eat youth food, and fists are afraid of being young. Especially women like me, who will conceive in October after marriage, and confinement after giving birth. Naturally, their kung fu is not as good as that of young people, so it is better to serve in the army in the future. .”

In fact, what Li Yuechen said was too light. There is no family planning these days. Anyone with good family conditions can have as many children as they can. When Wang Wuqiong gets married in the future, it is impossible to just have one child and finish the job.

If you have a few more births, your kung fu will be wasted in sevens and eighties, and you will no longer be suitable as a guard.

Wang Wuqiong didn't refute this: "It's true, this subordinate can't protect His Highness forever..."

"It's okay, anyway, I'm still working in the army, so it doesn't make much difference whether you want to be my guard or not." Li Yuechen waved his hand, "Where do you want to work at that time, or enter the military academy, it's up to you to choose!"

"Thank you, Your Highness, for your kindness..."

Li Yuechen smiled and waved his hands, no matter what, Wang Wuqiong was considered one of his own, so it was impossible to treat her badly.

The two walked aimlessly while chatting, and walked into the farm after a while.

Looking at the cows in different pens, Wang Wuqiong suddenly asked: "Your Highness, since the hatching room can increase the production of poultry, can this cow..."

Before he finished speaking, he saw Li Yuechen's eyes that seemed to be concerned about children: "How can cows and poultry be considered the same? But it's not your fault, maybe this is the cute side of the ancients..."

"Old man?" Wang Wuqiong was even more confused, and raised her hand to touch her face. Could it be that she looks like someone?

While the two were watching here, the logistical soldier who had just finished feeding the cattle came over to salute and say hello: "I've seen Your Highness!"

"Ah."

Li Yuechen looked into the feed bucket in his hand: "I just saw that you have changed several buckets in a row, and the feed is different?"

"Yes!" The other soldier replied, "Your Highness once said that we can also do our own experiments, so I put these cows in different pens and feed them with different feeds. If a calf is born in one of the pens in the future If it grows more, or if it grows stronger, it can be regarded as a good result..."

"Not bad, young man! Very persistent!" Li Yuechen praised with a smile, "This kind of experiment lasts for a long time, and many people don't have such patience. This state of mind is worth encouraging!"

Being praised by the princess, the other party raised his hand and scratched the back of his head in embarrassment, with a shy expression: "Thank you, Your Highness, for the compliment!"

Li Yuechen thought that he should give this young man a little reward, but princesses usually don't carry any money with them, so go back and tell Xiaodong when it's over.

Wang Wuqiong on the side curiously took out the feed from the bucket to have a look, twisted it with his fingers, and saw a lot of white powder.

"Is this... flour?"

The other party shook his head: "No, no, how can my subordinates be so wasteful? It's just that the logistics often grind beef bones into powder and sprinkle them on the ground as fertilizer. The subordinates are thinking about whether they can be mixed into the feed, maybe they can Let these cattle grow stronger."

Wang Wuqiong nodded slightly: "Well, this kind of idea is not bad, maybe beef can also be used in the future..."

Originally, she was going to praise her, but before she finished speaking, Li Yuechen suddenly turned her head, her usual calm expression became extremely astonished, and her bright black eyes widened!

The usually low and ethereal voice suddenly became extremely high-pitched: "Huh? What is added to this feed?"
