Three days, in a flash.

For Yu Zhiqian, the daily action is to go to the palace to say goodbye to the queen mother, and then little by little to implement his plan to empty the palace, so far a palace has not been completely emptied, if calculated according to the progress of the game, Yu Zhiqian's current progress is about to move a 10% palace, and there may be hundreds of thousands or millions of dollars away from the entire palace emptying, and there is a long way to go!

In addition, Yu Zhiqian just went to the Whampoa Military Academy to train the students, Yu Zhiqian underestimated the military level of the Yu Tang Empire, especially these 500 captains are still the elite of the elite in the army, except that they will be a little uncomfortable on the first day.

In the next two days, the adaptability of this group of captains has rarely made mistakes, every word and deed, every sitting and standing, they all begin to have a bit of that taste, and the obedience is very high, Yu Zhiqian was worried that this group of people would complain that these things are useless, but it is obvious that this group of captains obviously knows the importance of these things.

A strong army, discipline is the top priority, since ancient times, everyone knows, so everyone endured Yu Zhiqian's training methods, not to mention that Yu Zhiqian's teaching this time is not only so, but also various celebrities will teach experience.

Compared with the peace of the Whampoa Military Academy, Tsinghua Park is a crowd of chickens and dogs, a group of students are full of interest at first, but when they start the test, it becomes worse than death, and the data that comes out of each test is different.

"Li Bai, you just use the test, how about it? Is it tested? ”

Li Bai returned to his seat with a haggard face, and someone next to him immediately came to say hello, Li Bai glanced at Lu Su, and wanted to cry: "Brother Lu doesn't know, this water has no normality, and it can't ......be measured at all."

“……”

After Yu Zhiqian finished breakfast, he came to Tsinghua Garden with his lesson plan, and he was full of expectations that this group of guys would be able to come up with some results.

When Yu Zhiqian walked into the classroom, all he saw was a group of weak faces, Yu Zhiqian's face turned cold, this group of people didn't finish the homework they assigned......

Thinking of this, Yu Zhiqian suddenly realized a problem again, as if he had a new invention, it is estimated that he may be hated by tens of thousands of students in the future, homework is not available in this era, but he seems to be careless......

Yu Zhiqian looked up at the ceiling, fortunately there were no historians around, so he shouldn't have recorded this matter, otherwise......

"Ahem, ahem!"

coughed lightly, and all the students didn't dare to speak, but got up and saluted Yu Zhiqian: "I've seen His Royal Highness the Prince!" ”

"Excuse me, how are you doing?"

After hearing Yu Zhiqian's words, all the students, you look at me, I look at you, all lowered their heads, and did not dare to speak, after Yu Zhiqian glanced at it, only Lu Su looked confident.

"You don't all have measurements, do you?"

"Your Highness, we've all measured!"

"Then turn in your homework, you, what's your name from!"

"Your Highness, ...... of humble duties"

"Just say it here!"

"Your Highness, my name is Shen Kuo!"

"Poof!"

Yu Zhiqian almost didn't squirt out a mouthful of water, and looked at this guy, Shen Kuo? Mengxi pen talk seems to be this guy's work.

"That Shen Kuo, have you measured it?"

"Your Highness, it's been measured!"

After Shen Kuo finished speaking, he took a fold book, and his movements were twisted and pinched, Yu Zhiqian was stunned for a moment after reading it, a cubic meter of iron was only a thousand catties? Yu Zhiqian glanced at this guy after reading it: "You tested it yourself?" ”

"Yes!"

Shen Kuo was about to cry, this data was indeed tested by him.

"What about yours?"

Shen Kuo's rest of the data Yu Zhiqian didn't look at it, and directly skipped it, none of the data in it was right, if the difference was close, Yu Zhiqian could bear it, but it was too far behind......

"Lu Su, bring it!"

"Whoa!"

Yu Zhiqian, the excerpt sent by Lu Su, glanced at it, not to mention anything else, this guy's head is still relatively smart, and the things tested are good, mud, sand and other things that are easy to measure, Yu Zhiqian glanced at it, the data is still far behind, but it is not as outrageous as Shen Kuo.

"Li Bai, what about yours?"

Li Bai stood up with a twist, and after Yu Zhiqian glanced at it, he almost made a move on Li Bai, a liter of water is almost a catty, but Li Bai measured this data, a liter of water is about ten catties, I don't know what kind of water Li Bai uses? Ten times the mass of water?

"Forget it, this time it's just a test of your hands-on ability, and it's also my problem, I didn't teach you some measurement standards, today I'll talk to you about some basic concepts, cubes, squares, liters, grams, kilograms and so on!"

After finishing speaking, Yu Zhiqian took out the things he had prepared before, all of which were made by Zhu Youxiao, and the conversion method of the Yu Tang Empire was probably the decimal method, so this group of students could also accept simple decimal things.

However, the more troublesome are some units of measurement that are not commonly used, such as grams and liters.

"The volume of an object is in cubes, and the volume of water is in liters!"

"Your Highness, then why is 500 grams a catty?"

"Because everyone is used to it now, it will be slowly changed in the future, but it will take decades!"

"Your Highness, so a liter of rice, rice is also a liquid?"

"This is a way of being used by the people, do you understand scientific research now? These data are for scientific rigor! ”

"Okay, I'll give you some simple measurement methods now, Li Bai, you listen to me, one liter of water is roughly equal to five hundred grams, that is, the water ......"

After today's class, Yu Zhiqian can be said to have a dry mouth and a rising temper, and finally understood why he was beaten by the teacher when he was a child, it was really because he was too naughty, and he loved to ask questions blindly when he had nothing to do, and it was strange not to be beaten!

However, on the whole, Yu Zhiqian is still quite satisfied today, at least some things have been passed on, this group of students can go back and continue to measure, for the meaning of measurement, Yu Zhiqian is not clear, but he can get some basic data, in order to play a mobile role in future research.

In a month's time, Yu Zhiqian's plan to empty the palace is still being implemented, but the goal is still far away, and the construction of the East Palace is also proceeding rapidly.

"Which of you can lift this stone?"

Yu Zhiqian pointed to a large stone in the open space not far away.

"Your Highness, the volume of this stone seems to be at least two cubic meters, or even more, according to the quality tested by some common stones, it must weigh at least four or five tons, I'm afraid this is not something that a person can lift, right?"

Cheng Chumo walked in front of the stone, looked at it carefully, and came to a conclusion, Yu Zhiqian nodded, the teaching results during this period of time still look good, at least Cheng Chumo knows how to analyze.

Li Bai and the others also circled around the stone twice, and came to a conclusion similar to Cheng Chumo's, Yu Zhiqian breathed a sigh of relief, it was good if he couldn't lift it, he had seen Cheng Xiang and others explode in force before, and he had always suspected that this era was a high-martial world, such as the mythical version of the Three Kingdoms, but now it seems that it is not.

"Then now I'm going to test you again, how can you lift this stone, in any way!"

Hearing Yu Zhiqian's inquiry, everyone began to think, and after Cheng Chumo walked around the stone for half a circle, he slowly spoke: "I think my sister Cheng Xiang should be able to lift it!" ”

"Shut up!"

Yu Zhiqian couldn't wait to slap this guy away, Cheng Xiang was already pregnant, and he actually wanted Cheng Xiang to move this stone, this guy didn't know how to write the word death, right?

"There it is!"

At this time, Yu Chi Yulin's eyes lit up, and then he walked in front of the stone, moved it vigorously, the stone stood still, Yu Chi Yulin acquiesced to Cheng Chu, and signaled to come over to help.

The two of them used their strength to eat, one on one side, not to mention anything else, but they really began to shake, Yu Chi Yulin shouted: "Chu Mo, come on, move!" ”

"Good!"

The two of them used all their strength to keep moving, Yu Zhiqian patted his head vigorously, he just praised them twice, and these two fools got carried away.

"Okay, stop, you guys are learning from this palace now, you have to use your brains, not work hard, and use your brains to do things!"

Cheng Chumo and Yu Chi Yulin looked at the big stone in front of them and muttered to each other: "You kid definitely didn't use his strength!" ”

"You didn't exert yourself!"

"Didn't you say you could lift a thousand pounds?"

"That's four or five thousand pounds!"

Yu Zhiqian decided not to care about these two fools anymore, let them go, there is no help, how to play how you like, let out a long sigh, and looked at the rest of the people: "Have you thought of any good ways?" ”

"Your Highness, I think we can dig some drainage troughs underneath, and then set up a raft, and then dig another river, and it's ......"

Yu Zhiqian nodded after hearing this: "You can indeed carry the stone away in this way, but do you not consider the cost of doing so, and how much labor you pay?" ”

Hearing Yu Zhiqian's words, Lu Su also closed his mouth and continued to think, at this time, Li Bai's eyes suddenly lit up: "Your Highness, when the grass people were in Chengdu, they saw someone hanging a giant tree with a rope, we can also use a rope to tie the wood, and then find a few wrestlers to spread a rolling log in front of ......"

These methods are good, Yu Zhiqian nodded with satisfaction: "Very good, at least compared to those two guys, you know how to use your brains, but your methods are not the most labor-saving methods, let me show you how this palace lifted this stone by one person today!" ”

After Yu Zhiqian finished speaking, he asked Zhang Zhan to take out the pulley set that had been prepared long ago, and then began to install it, this set of equipment Yu Zhiqian has been studying for a while, and the construction of the East Palace encountered some problems two days ago, Yu Zhiqian remembered.

A group of students watched Yu Zhiqian take out round things and was busy, and many people from the Ministry of Engineering also came to check and see how the prince solved the problem of this stone.

This stone just blocks some of the things in the construction of the East Palace, and if it is not demolished, it will not be built well according to Yu Zhiqian's plan, and it is just right to teach this group of students a lesson, so that they can know that science and technology are the primary productive forces.

More than ten minutes later, Yu Zhiqian watched the pulley sets be assembled one by one, and finally nodded with satisfaction, grabbing the rope with one hand and looking at the rest of the students.

"Do you think Hongu can pull this stone up with one hand? Think you can pay five, you can't pay ten, bet or not? ”

This group of students looked at each other, no one dared to bet, Yu Zhiqian had won a lot of their money during this time, they didn't dare to bet easily, Yu Zhiqian waved his hand: "Since you don't bet, then look at it, how did this palace do it!" ”

After finishing speaking, Yu Zhiqian pulled hard with his hand, and the rope began to operate through the pulley, and then the stone was slowly and little by little shaking and finally pulled up, Yu Zhiqian was also a little difficult when he pulled, no way, the equipment was still a little flawed, and the friction was a little big.

But even so, it was already very remarkable, and many people watched with wide eyes as Yu Zhiqian easily pulled the stone up.

In ancient times, there were actually pulleys, but this kind of pulley was a single pulley, and it was not made into a pulley group like Yu Zhiqian, and Yu Zhiqian's doing so was also an innovative invention.

Yu Zhiqian pulled up the stone about half a meter from the ground, and immediately someone filled the rolling wood underneath, ready to remove the stone.

After the rolling wood was loaded, Yu Zhiqian glanced at the stunned students: "Now can you understand the importance of the things that this palace handed over to you?" ”

Many people's eyes lit up, and they nodded slowly, Cheng Chumo watched the stone being placed on the rolling wood, went up and moved it again, but found that he still couldn't move, and then came to Yu Zhiqian, pulled the rope on the wheel group with his hand, and easily moved the stone.

"How is this possible?"

"It's amazing!" Lu Su opened his mouth wide and looked at the stone that was lifted, before he had time to try it himself, Lao Qi didn't know where it came from, and he pulled it up hard, and recently this product also ran to Yu Zhiqian's side from time to time to listen, as if the invention of the steam engine had encountered some bottleneck.

"With this thing, it will be much faster to repair the house or something in the future!"

This is true not only of the craftsmen around the students, who are pulling dozens of people together, but now it seems that only one person or a few people will be needed in the future.

Yu Zhiqian looked at the group of students with a smile and waved his hand: "Let's go, go back to the school, and the palace will assign homework to you!" ”

There are actually a lot of things that can be taught, but there are not many things that Yu Zhiqian can teach and understand, and he can only teach with a hoe in the east and a mallet in the west.

However, Yu Zhiqian believes that as long as he continues to teach, he will one day blossom and bear fruit.

"However, if you continue to teach like this, I think the possibility of playing with your phone before you die is a little low!"

Yu Zhiqian looked at a group of students who were whispering in a low voice, and sighed in a low voice, Yu Zhiqian's ambition is not big, unlike the guy called Ling Ran who wants a bumblebee or change the world, he just wants to play with his mobile phone once before he dies, even if it is just a game of snake.

ps: I went for a preoperative check-up today and had surgery on Monday, which is a little tired! ~
