Daming: Old Zhu, we agreed not to rush!

Chapter 191 Pulley Block!Children are strongmen too!

"Woke up!"

"Woke up!"

"Really woke up!"

……

In front of Fengtian Hall, cheers resounded one after another.

No one expected that the three princes could actually lift this big copper tripod weighing more than 700 jin.

This is nothing short of a miracle!
"Fourth brother, put it down and replace me!"

Zhu Xi came to Zhu Di's side and said excitedly.

"it is good."

Zhu Di nodded, and then slowly sent the rope up.

Bang!
The big bronze tripod fell to the ground with a crisp sound.

"hey-hey!"

Zhu Xi grabbed the rope with excitement on his face.

With the pulling of the rope, the big bronze tripod was lifted into the air again.

Even after watching it again, the people around were still dumbfounded.

Zhu Xi is older than Zhu Di, but he is only a teenager.

Such a large copper tripod is like a very light object.

If it wasn't for the crisp and heavy sound when it landed, someone might suspect that the copper tripod is fake.

"Third brother, come and try."

After Zhu Xing finished the test, he turned to look at Zhu Xing.

"Okay, second brother."

Zhu Bian nodded, compared to Zhu Bian, he was more excited.

Because he is the main person in charge, it can be said that he is the backbone of the tripod.

After Zhu Yan finished pulling, even Lao Liu and Lao Qi, who were watching from the side, were very excited and wanted to try their hand.

It was Zhu Yuanzhang who spoke and stopped the two of them.

Zhu Yuanzhang knew the danger before.

Zhu Zhen and Zhu Wei are still too young.

"Royal Father." X3
The three of Zhu Xun, Zhu Xun, and Zhu Di came to Zhu Yuanzhang, very excited.

"Good good!"

Zhu Yuanzhang nodded, looking at his three sons, he was quite satisfied.

Not only because they completed the tasks they set, but also because of the solidarity and cooperation of the three.

They are all brothers and sisters, as it should be.

After Zhu Biao ascended the throne, his younger brothers were his most solid support.

Mu Ying looked at them and nodded towards them directly behind Zhu Yuanzhang, the admiration in her eyes was very obvious.

"Father, the sons and servants have completed the mission of the father, and it is time for the father to fulfill his promise."

Zhu Xi was the biggest, and said directly to Zhu Yuanzhang.

Zhu Yuanzhang nodded and said, "Well, I will not forget what I promised you."

"It's just that three of you completed this task, but there is only one promise. Have you decided what you want?"

At that time, Zhu Yuanzhang said that whoever finishes first will make a promise.

Now that the three of them have completed it, it doesn't mean three promises.

Zhu Xi immediately said: "Father, my sons and ministers have discussed it a long time ago, and we still want to listen to Mr. Su's class again."

Su Jing's class!

As early as when it was reasonable to make leverage, the three of Zhu Xi had already discussed it.

The lessons that Su Jing taught them during the Mid-Autumn Festival have given them endless aftertaste until now.

Of course, the main thing is to compare.

The teachers in Damoto Hall teach the Four Books and Five Classics every day, either by rote memorization or by rote memorization.

They experienced Su Jing's teaching method once, and they couldn't stop it.

More importantly, the three of them were also clear, or in other words, Zhu Yan knew what kind of request would satisfy Zhu Yuanzhang the most.

"Oh, is this what you want?"

Zhu Yuanzhang was a little surprised.

At least, this guy Zhu Xi shouldn't want this.

"Yes, Royal Father, please fulfill your request!"

The three nodded in unison.

Zhu Yuanzhang waved his hand and said, "Okay, I promise you, but not now."

"Thank you, Father!" X3
The three of Zhu Xing immediately thanked each other.

Although Zhu Yuanzhang did not specify a specific time, but in front of Fengtian Temple, it will definitely be fulfilled.

"Today I will allow you not to go to class."

Zhu Yuanzhang said very happily.

Being able to lift the cauldron with his own strength, the performance of these three people has already satisfied him quite a lot.

"really?"

Zhu Xi was the most excited and asked excitedly.

For him, it is really painful for him to attend class, but it is a pleasure not to attend class.

Zhu Yan and Zhu Di seemed calmer.

"Second, it seems that you don't really want to go to class."

Zhu Yuanzhang looked at Zhu Xi and said, "Since that's the case, why do you want Su Jing to teach you?"

Suddenly asked by Zhu Yuanzhang, Zhu Xi didn't know how to answer for a while.

He could only lower his head, faltering, unable to say one, two, three, four, five.

Su Jing's class is indeed very interesting, but for Zhu Xi, it is only compared with the class in the main hall.

He is happiest if he can skip class and read books.

"Father, it's all my son's idea."

The third child, Zhu Yan, stepped forward and said, "I proposed to use this promise of my father to consult Mr. Su."

This time the tripod was lifted, Zhu Yan was in control of the whole process.

Although Zhu Xi is the second child, he also knows who did it.

Without him, the third child, Zhu Yan, can do just as well.

He is not smart, and his reading is average, but he is not stupid.

"Third brother, it seems that you really admire Su Jing."

Zhu Yuanzhang looked at Zhu Fen and said.

Among these sons, Zhu Yan was indeed quick-witted and quite outstanding.

But, does Su Jing really have such a high status in Zhu Bian's heart?
Zhu Wei replied: "Reporting to my father, in fact, it is thanks to Mr. Su that I was able to complete today's work."

Ok?
Zhu Yuanzhang's words made Zhu Yuanzhang stunned.

Zhu Yuanzhang and the three of them have been trying to find a way to lift the tripod here these days, and Zhu Yuanzhang is concerned about the daily situation.

Su Jing stayed in Lishui County well, and couldn't teach them.

"What does this have to do with Su Jing?"

Zhu Yuanzhang asked.

Zhu Wei replied: "Last time, my eldest brother was going to teach us on behalf of Mr. Su, and my son learned a set of methods to solve problems."

"It is precisely by this method that the emperor's order can be fulfilled."

"And this set of methods was actually taught to my elder brother by Mr. Su."

Zhu Yan's class is really serious.

What has been learned can also be remembered and used.

Zhu Yuanzhang frowned and said, "The solution to the problem? Has Su Jing taught this?"

Zhu Wei immediately replied: "Yes, the main core is to find the main problem, disassemble the problem, and then solve it."

"For example, if the emperor asked us to lift the tripod, it is definitely not possible to rely on our own strength."

"In the case of not relying on other people's strength, you can only use equipment, and lifting the tripod can be converted into lifting heavy objects. Naturally, Erchen thought of the Ministry of Industry."

"The Ministry of Industry is responsible for the construction, so there must be equipment and methods for lifting heavy objects. Erchen found the blueprints and some books in the Ministry of Industry."

"According to the method in the blueprints and books, I finally succeeded in lifting the cauldron."

Zhu Yan clearly explained the steps and ideas to solve the problem.

It is not the principle of leverage, but how to think about solving problems when they encounter problems.

In fact, this is just the solution to all problems mentioned by Su Jing when teaching Zhu Biao and Zhu Wei.

Disassemble the problem, find the core, and then solve it step by step.

After all, it is a guiding method.

Zhu Biao briefly mentioned it when he was teaching on behalf of his younger brothers.

At that time, Zhu Yan carefully wrote down and implemented it.

Facts have proved that with the guidance method, the efficiency of problem solving will be greatly improved.

Listening to Zhu Yuanzhang's description, Zhu Yuanzhang also nodded unconsciously and said, "Not bad, old three, you've done a pretty good job."

Although Lao Zhu had known for a long time, the success of this matter was mainly due to the credit of the third son Zhu Yan.

But I was very satisfied when I heard Zhu Yan explain his thoughts on how to solve this problem.

Even Mu Ying who was on the side couldn't help admiring: "Brother Yang has a clear mind and acts decisively, it's really amazing!"

What does it mean to have a brain? This is what it means to have a brain!

"Father praised it absurdly. Everything is due to Mr. Su."

Zhu Yan turned to Zhu Yuanzhang and said, "By the way, just now I heard from brother Mu Ying that he just learned a set of methods of lifting a tripod from him, and I am very curious."

Just now Mu Ying offered to help them, but because they had to do it by themselves, Mu Ying just watched from the sidelines.

"Ying'er, then you can give them a demonstration."

Zhu Yuanzhang looked at Mu Yingdao who was on the side.

Zhu Yuanzhang is also very curious about how Zhu Biao raised the alchemy furnace.

Now that Zhu Yan mentioned that the equipment on the scene is also complete, and everything is just right.

"Yes, Father."

Mu Ying nodded, and then took out a few movable pulleys from the backpack behind her.

According to what Zhu Biao taught him, the movable pulley was assembled into a pulley block.

The rest is to basically follow the leverage made by Zhu Yan.

The people next to him looked a little strange, but they still observed patiently.

In a short while, everything was assembled.

"Brother Zhen, come and try."

Mu Ying said to Zhu Zhen, the sixth child who was standing in the distance.

Let Zhu Zhen try it!
This stunned all the people present, and the danger was not so much to worry about.

After all, Zhu Yan, Zhu Fan and Zhu Di have tried it, and there is no major problem.

But how old is Zhu Zhen, this strength is far from Zhu Xi and the others.

I'm afraid I can't pull the rope at all, right?

Could Mu Ying be joking?

"Brother Muying, can I really do it?"

Zhu Zhen was very excited, but still asked.

Mu Ying smiled and said: "Try it and you'll know, but according to what the prince said, your strength is enough."

The movable pulley block is actually a combination of multiple labor-saving levers. The levers just now can already allow Zhu Di to pull the big tripod.

Now that the pulley block is added, it is not impossible for Zhu Zhen.

Zhu Zhen was still a little timid, and turned to look at Zhu Yuanzhang.

After receiving Zhu Yuanzhang's nod, Zhu Zhen came to Mu Ying's side, holding the rope with two small hands.

"Hold on, and just run back."

Mu Ying instructed.

"Well, I see."

Zhu Zhen nodded, grabbed the rope and started running.

The rope kept moving backwards, and the pulley block also rotated rapidly.

The power was transmitted, and the big bronze tripod on the other end of the lever actually rose slowly.

It was like a miracle!
Obviously, I have watched it three times in a row, but this time, everyone's eyes are full of disbelief!

Even Zhu Zhen himself was dumbfounded.

How is this possible?
A child who is only seven years old can lift a big tripod of seven hundred catties.

It’s too shocking!

Even Zhu Yuanzhang's brain was buzzing.

Mu Ying was very careful, under his control, the rope retracted little by little, and let the cauldron down.

"Brother Muying, how did you do this?"

Zhu Yan came to Mu Ying and asked him.

Obviously, the operation of the sliding pulley block was still completely unknown in Zhu's eyes.

On the other hand, Kaos, who was not far away, was shocked.

Pulley block!

Although Te has never uttered a word to help these princes these days, he has seen all of Zhu Yan's search for information and blueprints.

Originally, he thought that Daming should not have a pulley.

After all, this is the Imperial Palace, and the Ministry of Industry is the organization that manages the entire Daming Royal Project.

There is no movable pulley here, so Daming should not have one.

Unexpectedly, an exquisite movable pulley block appeared in front of my eyes.

It has to be Su Jing!
In Kaos' heart, he became more and more curious about this Mr. Su.

Mu Ying patiently explained the application of this pulley block to Zhu Fen, but he was not very clear about the reason why it saves effort.

Mu Ying, who has never studied mechanics, had only a half-knowledge when she listened to Zhu Biao's explanation.

"Probably so."

Mu Ying said.

Zhu Fen looked at the pulley block, and his doubts did not disappear, because Mu Ying only explained how to use it, but he didn't know why.

But he also heard it, that's all Mu Ying knew.

"Ying'er, what did you call this thing?"

Zhu Yuanzhang asked.

Mu Ying replied: "A single piece is called a moving pulley, and a combination is called a moving pulley block. It can amplify the power of one piece many times. Some heavy objects that are difficult for ordinary people to lift can also be easily lifted. It is very practical."

"Father also saw that even if he is only brother Zhen, he can become like a strong man."

"Mr. Su's ability is truly earth-shattering, and it's not an exaggeration."

When introducing the pulley, Mu Ying did not forget to praise Su Jing.

Just because this pulley block is indeed too powerful.

A device that can save such labor can be said to be very versatile.

Especially in the Ming Dynasty, there were no large equipment such as cranes and forklifts, and many things could only be done by manpower.

Something like a moving pulley block can already be regarded as an advanced tool.

"Moving pulley block? This thing is so magical, Su Jing surprised me again!"

Zhu Yuanzhang picked up a movable pulley and looked at it carefully in his hand, feeling quite emotional in his heart.

But as the king of a country, it is not easy for him to be too excited.

Zhu Yan said: "Father, if the project of the Ministry of Industry can use this thing, it will save a lot of manpower and greatly reduce the expenditure."

"The movable pulley created by Mr. Su is really beneficial to Daming!"

Zhu Yan was quite far-sighted, and he hit Zhu Yuanzhang's heart right away.

In the current Ming Dynasty, all kinds of construction are very necessary.

But there is also a lot of demand for food, and manpower is very important.

The movable pulley is so labor-saving, it can indeed reduce the application of a lot of manpower.

Good for the country!

"Third brother, that's right, then I will give you a task, and you will teach the Ministry of Industry how to move the pulley."

Zhu Yuanzhang looked at Zhu Yan and said.

Zhu Yan immediately said: "Yes, father!"
