Great Qin Shi Empress

==·Power Generation·==

Lin Qian doesn't know what happened in the Western Regions, she is worrying about another matter now——

It's not a big deal, isn't the weather getting colder after the Chinese New Year?Because the only edible oil used by the common people today is animal fat, which directly leads to the fact that when the weather is cold, the street stalls will not be able to open because the fat is easy to solidify.

Lin Qian hadn't noticed this before.

After all, she has to work every day, and she can let the royal chef in the palace make whatever she wants to eat, so there is really no need to pay attention to those street stalls.

But sometimes, when people eat, they eat the atmosphere.

So even if the taste of the street stalls is not as good as that made by Yuchu, Lin Qian will occasionally ask someone or himself to buy some skewers from the stalls to eat when he thinks about it.

Just treat it as a snack to satisfy your hunger.

But when she went out today, she was hungry, and for some reason, she suddenly wanted to eat skewers, so she thought of going to a small stall to grill a few skewers.

then……

Lin Qian wandered the food street from beginning to end, but didn't see a single stall.

Wang Qiang was puzzled: "What are you looking for?"

Lin Qian didn't want to hide her thoughts, and said directly: "Suddenly want to eat skewers, why hasn't the family seen it?"

Wang Qiang suddenly realized, and then quickly explained: "It's winter, and the lard and mutton oil used for grilling skewers has just been removed from the oven, and it will solidify after a while, and the fat dyed by the seasoning is like mud. If you stick it on the food, you will lose your appetite, so those who sell skewers have changed to boiled in winter."

"If it is boiled, there is soup, and it will be warm when eaten, and it will take longer to cool down."

Lin Qian paused: "Is there no vegetable oil?"

Wang Qiang was at a loss: "What is vegetable oil? Can plants still produce oil?"

Lin Qian raised his forehead, never expecting that he would forget such an important thing.

She sighed, and then explained: "The fruit of some plants has a lot of oil content, which can be extracted by machine, and the most common one is soybean."

In addition to soybeans, rapeseed, peanuts, and even corn can also be used to extract oil.

These are not very difficult to obtain.

but……

Maybe animal fat tastes better?Lin Qian was in a daze for such a long time and didn't expect to get the vegetable oil out.

She was not in the mood to eat outside, so she hurried back to Xianyang Palace with Wang Qiang.

Seeing her, Ying Zheng quickly asked, "Why didn't you come back until now? Have you ever had lunch?"

Lin Qian shook her head: "But don't worry, I have something to ask you."

Ying Zheng frowned: "Is it urgent?"

Lin Qian was stunned for a moment, then shook her head: "It's not a day or two away..."

"Then let's eat first."

Ying Zheng called the waiter directly and asked him to go to the kitchen to order food.

Seeing the servant trotting to order food with his own eyes, Lin Qian looked at him helplessly: "There is no need to be so anxious, isn't there a lot of snacks in this palace? It doesn't hurt me to eat some padding."

After saying that, he got up and went to get some snacks such as candies and biscuits.

While Lin Qian was eating, Ying Zheng was watching.

She looked a little uncomfortable, so she simply talked about the business: "I came back from going out today, and I wanted to buy some skewers on the street. Only then did I know that the lard is very easy to solidify when the weather turns cold, so I remembered Oil can be extracted from plants."

Ying Zheng was stunned: "Extract oil from plants?"

Lin Qian was about to explain. After thinking about it, she simply found the modern host and asked her to help find a copy of the evolution process of oil extraction machines from ancient times to the present.

Because of the lessons learned from the past, Lin Qian chose to read the things himself after getting the things this time, and then handed them over to Ying Zheng——

After all, she was really worried that the people on the modern host side would carry private goods.

After reading it, he was sure that there was no problem, so Lin Qian handed the machine to Ying Zheng: "This is a machine for extracting oil from plants. Although the efficiency of extracting oil from plants is not very high, crops such as soybeans are more common and cheaper after all. , not as rare and expensive as animal fat."

Ying Zheng was also aware of the problem that the common people had difficulty eating oil, so after looking at the blueprint, he directly called the Mohist Juzi and handed it over to the other party.

The Mohist Juzi hadn't entered the palace for a while, and he was a little excited to see Ying Zheng and Lin Qian.

But the attention of Lin Qian and Ying Zheng did not fall on Juzi——

The Mo family's giant son entered the palace this time, and he brought Mo Shu with him.

Ying Zheng glanced at the young man who had grown up and was tall and straight like a little Bai Yang, and asked, "You brought Mo Shu into the palace, but what's the matter?"

Juzi subconsciously wanted to answer, but changed his tone at the last moment: "Your Majesty's matters are more important. I don't know about His Majesty's call this time, but is there anything that I need my servant to do?"

Yingzheng didn't hold back, and directly handed over the blueprint to Juzi: "This machine is said to be able to extract oil from plants. You can use it to study it. It's best to reproduce it as soon as possible."

Juzi took a cursory glance and nodded his head and replied: "Don't worry, Your Majesty, this machine has a simple structure and can be easily built according to the blueprint. In less than five days, I will definitely make this oil press machine for you to see."

Ying Zheng and Lin Qian looked at each other, but they didn't feel that Juzi was talking big.

After all, Juzi himself is very talented. He has done the thing of reproducing the machine on the blueprint a long time ago. This time, it is not difficult at all; in addition, he has learned a lot of modern scientific knowledge during this period, and his own strength has long been beyond his reach. On the same day, it is really very simple to reproduce the oil press.

but……

Looking at Juzi, the two felt that his attitude towards the oil press was a little careless.

Juzi noticed the scrutiny in the eyes of the two people, he was stunned for a moment, and quickly explained: "Your Majesty and Marquis Gu Feng summoned the minister today just for this oil press?"

Ying Zheng frowned, looking at Juzi with dissatisfaction.

Oil is related to people's lives, and it is the most important livelihood issue that needs attention. Juzi's tone when talking about the oil press makes him very disliked.

Even so, Ying Zheng nodded: "I planned to have someone hand over the drawings to you directly, but remembering that you and I have not seen each other for a long time, so I simply called you into the palace to ask, where have you been in the Mo family recently?" What is the workshop researching?"

Although the Mohist Juzi had a special status in the Qin State, he did not hold a serious official position, and he had nothing to be responsible for except weapons and scientific research, so the Mohist Juzi had very free time.

At least other officials must go to court every day, but if the Mohist giant has something to do, he can ask for leave directly.

And Ying Zheng said that the two hadn't seen each other for a long time, because the Mo family giant had found Ying Zheng some time ago, and took a full month's leave. After a month, he disappeared again, and asked someone to enter the palace to take half a month's leave.

Juzi of the Mo family had never taken such a long leave before.

And even if he asks for leave, he has always only entered the palace to find Ying Zheng himself, but there has never been a precedent for asking someone else to enter the palace to ask for leave.

Unexpectedly, when Juzi heard this, a smile immediately appeared on his face: "Your Majesty is concerned, and I don't want to miss the court meeting, but the recent research is too important, and I have to ask His Majesty for leave. The court meeting is over."

Lin Qian became interested in an instant: "I don't know if Juzi can tell you, what have you been researching recently?"

Since Lin Qian traded research materials and teaching materials from Sally's world and the modern world, the frequency of her visits to the Mohist workshop has been greatly reduced, from going to the Mohist workshop several times in the previous month to not seeing each other in a year Had to go two or three times.

When Lin Qianzhi went out to work on water conservancy projects, she hadn't even been there for several years.

It's not that there is nothing for the Mohists to study, but that this group of people immediately immersed themselves in the new knowledge, and then immediately verified the knowledge they had learned with the knowledge they had mastered before, and the research invented many things. Less good stuff.

Things like kaleidoscopes, cameras, etc. were independently developed by the Mohists relying on the knowledge in books, and have almost nothing to do with Lin Qian.

Seeing this, Lin Qian was worried that if she frequently gave them modern scientific and technological products for research, it would not only disturb their research ideas, but also hinder their progress, so she did not go to Mojia Juzi again unless it was necessary.

Because of this, she doesn't know much about the things recently researched by the Mohist Workshop.

Juzi laughed loudly: "I brought Mo Shu into the palace today, and there are mainly two happy events that I want to report to Your Majesty. One of them is that the idea of ​​combining steam engines and ships that Mo Shu mentioned before was finally approved by us." Achieved!"

"The second one is that Mo Shu recently created a machine that can generate electricity based on the magnetic induction phenomenon in the book!"

"Power generation?!"

==·ship·==

Lin Qian finally figured out why the Mohist Juzi brought Mo Shu into the palace, and why he was so indifferent after seeing the blueprint of the oil press——

Because he has more important things in his hands!

Lin Qian looked at Mo Shu in disbelief: "Is what Juzi said true? You really made the generator through the electromagnetic induction phenomenon recorded in the book?"

As he grows older, Mo Shu's temperament has become a lot calmer.

He paused for a moment and said seriously: "It can indeed generate electricity, but it should not be considered a machine, it can only be regarded as a device that can generate electricity."

After finishing speaking, he took a careful look at Juzi of the Mo family.

Juzi smiled and nodded, encouraging him to explain himself.

Then Mo Shu opened his mouth and said: "The principle of this device is very simple. It is designed through the electromagnetic induction phenomenon in textbooks, so the structure of the entire generator is very simple, even crude. But we did use this mechanical structure, Convert mechanical energy into electrical current."

Lin Qian got up instantly: "Can we go and see the generator you are talking about?"

Mo Shu was stunned for a moment, and said with a smile: "Of course, but there is just one problem... Although I have researched myself a machine that can generate electricity, there is no device or object that uses electricity as energy around me, and I have never researched a machine that can generate electricity. Objects that can store power."

Lin Qian was stunned, her eyes somewhat disappointed.

But after thinking about it, it is already very powerful that Moshu can research the power generation device through the textbooks. The reason why there are no objects that store electricity or use electricity after researching all the generators is mainly in the On Lin Qian.

Because the knowledge researched by others is directly brought into the world without going through the intermediate development stage, so many things need to be studied from scratch,

Unless, Lin Qian can make up for those things.

This is not too difficult.

but……

Lin Qian believed that with the presence of Juzi and Mo Shu of the Mo School, those things would be researched and invented by them sooner or later.

So she was fine.

Ying Zheng wanted Lin Qian to show drawings of objects that could store electricity and objects that used electricity, but he noticed Lin Qian's expression, and he paused for a moment, but he didn't speak.

He smiled: "The power generation device is temporarily useless, isn't there a ship combined with a steam engine?"

Juzi of the Mo family took a look at Mo Shu, saw that he was not depressed, and immediately smiled and said: "After all, I am not as smart as Mo Shu. After studying with many disciples for so many years, I finally made a decent one." Ships. If Your Majesty doesn’t mind, please visit the workshop.”

Lin Qian looked at Ying Zheng sharply.

Ying Zheng laughed, and stood up decisively under her gaze: "In that case, let's go over now."

……

A group of people soon arrived at the Mohist Workshop.

After entering the door, Juzi took the lead to take people to see the "power generation device" that Mo Shu talked about.

To be honest, it is indeed very simple, even simpler than the Faraday disc generator in Lin Qian's memory, and it looks disorganized. Some people believe that it is a child's randomly placed toys.

But Lin Qian went forward to try it himself, and the device could indeed sense a weak current after it was moved.

It's just that, and this device still needs to be further improved.

……

After looking at the power generation device, Juzi led the people directly to the small lake——

In order to build weapons better and faster, the Mohist workshop dug a very large artificial lake directly beside the open space inside the workshop.

Lin Qian looked around, and sure enough, he saw a wooden boat as tall as two people docked by the river.

When he walked up to the wooden boat, Juzi said, "Since there is a risk of falling into the water on the boat, I will not invite His Majesty and Marquis Gu Feng to experience it on board."

"Mo Shu," Juzi turned his head, "Go up and drive a boat around the lake."

Mo Shu's eyes lit up, and he got off the board immediately and walked into the cabin quickly.

I don't know how he did it, everyone only heard a "boom boom boom" sound, and the boat suddenly moved without anyone rowing or raising the sails.

The ship drew a half circle in place at first, then turned around and chugs away in another direction.

Lin Qian kept looking at the ship, and immediately saw the propeller at the stern.

Should the propeller be driven by a steam engine, and then drive the ship forward?

She looked back at Juzi, and couldn't stop admiring in her heart——

[Juzi and the others are really geniuses! 】

Ying Zheng paused, then glanced lightly at Juzi of the Mo family, his eyes flickered.

Juzi suddenly felt a chill: "???"

Lin Qian didn't take his eyes off the boat: the boat looked good in everything, but the material was still wood, and it was as slow as the first train, and it couldn't compare with the speed of a sailboat at all. .

Juzi seemed to have noticed Lin Qian's thoughts, and introduced with a smile: "Because this ship is made of wood, we must be more careful when using the steam engine, and the fire should not burn too much. But we have already thought about using steel to replace it." It is wood, and I have made a very small iron boat before, which can completely float on the lake. It’s just that the lake is too small and the buoyancy is not enough, so I can’t do related experiments for the time being.”

After hearing this, Ying Zheng nodded and said, "You can be allowed to experiment on the moat outside the city."

Juzi Mo's eyes lit up: "Thank you, Your Majesty!"

……

At this time, Mo Shu drove the wooden boat back to the original point. After parking the boat, he immediately put down the wooden board and got off the boat.

Lin Qian looked at the wooden boat and couldn't help but tugged at the corner of Ying Zheng's clothes: "Can you swim?"

Ying Zheng paused, followed her gaze to look at the ship: "..."

He was a little amused: "The widow has learned how to swim, but... can you drive this boat?"

Lin Qian was stunned for a moment, and sighed in disappointment: "I really don't know."

As soon as the words were finished, Ying Zheng led her directly to the boat.

Lin Qian was startled, grabbed Ying Zheng's hand with his backhand, and stopped him on the spot: "What are you doing?"

Ying Zheng glanced at her: "What else can I do? Try what it's like to take a boat."

Lin Qian's eyes lit up, and he immediately stepped up.

It is still very memorable to have taken the world's first steamship.

Seeing this, Juzi chased after him in two or three steps, and then entered the cabin.
