Lu Dynasty

Chapter 441 Compass

As soon as Cao's words came out, everyone in the conference hall was dumbfounded!Cheng Yu and the others looked at each other, not knowing what to say.Cao glanced at Cheng Yu and the others and said with a smile: "What's the matter, what I mean is that from today onwards, we must broaden our horizons and not just think about making the Han people eat and clothe themselves, but also let them eat well and dress well! Really! No, we'll just arrest Lu Feng and preside over the reform!"

Jiang Ji and Dong Zhao breathed a sigh of relief. Since Cao is not pessimistic, there is still hope.They just thought that what Cao thought was too beautiful.Capturing Lu Feng alive is something only Cao dares to think about!Xun Yu and Cheng Yu were not as at ease as Dong Zhao and Jiang Ji. They knew that my coal stove once again hit Cao's confidence.Especially when the shopkeeper said that, he was so proud that Cao felt that he had failed.Because Cao can see that the shopkeeper's love for me comes from the heart, and there may be people under Cao's command who love him like the shopkeeper loves me, but they will never love him like a small person, and Jimin Restaurant The shopkeeper is precisely the smallest person under my command who can't be smaller!
Cheng Yu understood Cao's thoughts, and he said with a smile, "Master, the shopkeepers of Jimin Restaurant were all adopted by Lu Feng since childhood, just like Lu Feng's sons. They love Lu Feng just like their own father. Children will think that their father is the best. Besides, Lu Feng is indeed no less than your master! Master still needs to work hard, we must not lose to him!"

"I understand! Zhongde don't have to worry! Tomorrow I will ask someone to install a coal stove for His Majesty. Wen Ruo, I will leave this matter to you! As for Lu Feng's briquette, you take five thousand gold to the shopkeeper and let him First send [-] pieces, and after delivery, give Lu Feng [-] gold!" Cao still really wants to use my coal stove.The ratio of gold to silver in the Han Dynasty was about one to ten, so Cao's calculation ability is still good.

"My lord, is one hundred thousand too many?" Xun Yu didn't want to have anything to do with me from the bottom of his heart.Because Xun You wrote to tell Xun Yu that he was forced to stay by me.Xun You also said that if he didn't stay, I would attack Yingchuan and slaughter the Xun family.In Xun Yu's eyes, I am an executioner and butcher who disrespects imperial power and indiscriminately punishes and kills!Although I also have the title of scholar, I am worthless in Xun Yu's eyes!

Cao shook his head and said, "I have no fewer generals and counselors than Lu Feng, so I can't use the coal stove by myself but not let my subordinates use it! Since it was installed by Liu Xie, the other clan members will naturally also install it! Sometimes, I’m afraid it’s not enough!” Cao really didn’t want to care about those officials who disagreed with him every day, but he couldn’t be like me, just slaughter anyone who didn’t like it.Because my army is in my own hands, and most of the troops under Cao's command are in the hands of the aristocratic family!For example, Chen Deng in Guangling, Cao Bao in Xuzhou, Chen Qun in Xuchang, and the Xun family in Yingchuan, Cao would not dare to offend them.If it were me, if any aristocratic family dared not cooperate with my policy, let's ask Lu Bu to talk to him directly!

Cao's business is doing well, and Yuan Shao's business is also doing well.Yuan Shao was even more fooled than Cao, and actually bought me a carbon for one gold.Yuan Shao also said that only people like me who came from a businessman would occupy a high position and want to do business.That being the case, let Yuan Shao reward me!Well, let's not argue with Yuan Shao, only by muffled can we make a fortune!

We feel at ease for having blackmailed Yuan Shao and Cao!Taking advantage of my comfort, Ma Jun ran over to me and said, "My lord, I remember that there was a kind of compass car recorded in ancient books, and I want to try to make it! That thing is very good for knowing the way when marching and fighting!"

"Did the keel water wheel come out?" I asked Ma Jun to make the water wheel, and now he wants to make the guide wheel, I am really speechless!
"Not yet! It's just..." Ma Jun scratched his head in embarrassment and said, "Pu Yuan said that there are pictures of finished products, so I don't need to develop them, just let him make them! Now Xiao Yuanzi has More than half of it was created, so I naturally can't take his credit, so I want to find another research thing, of course, this thing must be practical!"

"Go and get two iron needles, a piece of thread, a bowl of water, a piece of paper, and a magnet!" The compass is such a simple thing. In modern times, kindergarten children can make a few simple ones. Why study that old-fashioned compass car?When that thing is on the battlefield, it needs to be pushed by a special person. When encountering a rough place, maybe one person is not enough to push the cart!

"My lord wants needles and threads to mend clothes? What are the water, paper, and magnets for?" Ma Jun didn't know what I was going to do, and felt a little puzzled.Still, he brought the things as I ordered.

I picked up two needles and rubbed vigorously along the needles, of course only in one direction.After rubbing until the two needles became magnetic, I tied one of the needles with a thread and hung it up, and the other needle passed through the torn paper and threw it into the water bowl.When the two needles were still, I pointed to the two simple compasses and said, "Look for yourself, one end is facing south and the other is north. Turn around and paint the two ends of the needles with different colors to mark north and south. This is a simple compass." !"

Ma Jun looked at me dumbfounded and asked, "Master, why do you know how to make a compass? What is its principle?"

"Okay, let me tell you briefly, but the following words are not allowed to be circulated, you just know it!" Seeing Ma Jun nodding, I took the paper left over from making the compass just now, drew a ball on it and said: "Actually We humans live on a big ball, I call it the earth! The earth itself has a kind of suction, which attracts people to it. And this kind of suction becomes stronger as it goes to the two ends of the earth, and the magnet is the most sensitive This kind of attraction. You should have also discovered that when two long magnets are put together, sometimes they repel each other, and sometimes they attract each other. In fact, what repels each other is the magnetic force of the same sex, and what attracts each other is the magnetic force of the opposite sex. The earth is It is equivalent to a giant magnet, and all magnets will always face south and north without external force! What we need to do is to reduce the influence of external force on the magnet, so that we can make a compass!"

Ma Jun finally put his chin on the ground, I really doubt whether his mouth will be able to close in the future.Ma Jun hugged me and said, "My lord, tell me what else you know! How about I worship you as my teacher?" Ma Jun was about to kneel down in front of me to worship my teacher!
