"The emperor is here!!" The crowd found that Zhu Yuanzhang had arrived, so they stopped the noise, knelt down and worshipped, and then stepped back to make way for Zhu Yuanzhang and several ministers.

"Di'er, what the hell are you doing?" Zhu Yuanzhang asked with a fixed expression.

"Father, the emperor, the sons want to lift this big ding." Zhu Di said confidently, "According to the inscription on the big ding, this tripod weighs two thousand catties, and it was originally in the Jiming Temple, and it was specially transported by the sons of the ministers, just to show everyone the power of physics." In this way, we can tell the people of the world that the physics taught by Mr. Qin is very practical. ”

"Your Majesty, the former Yuan of Jinling Daru Hua Chi Kuangkuo Timur, indulged in Buddhism, often talked with the monks of Jiming Temple about the scriptures, this tripod was cast by the craftsman to Jiming Temple." Gao Qi was well-informed and memorized, and started popular science for Zhu Yuanzhang.

"Zhu Di, are you sure?" Zhu Yuanzhang asked.

"Father, don't worry, the son is completely sure." Zhu Di is full of confidence.

Zhu Yuanzhang turned his head to look and saw that the big tripod was indeed very heavy, and it could not be lifted by human beings, but there was a rope on top of it, and there were several pulleys hanging on the rope.

Zhu Di strode in front of Da Ding, put one hand under the Ding, and pulled the rope with the other.

In the exclamation of the crowd, the two-thousand-pound Dading slowly rose.

"Did King Yan really lift it?"

"It seems to be very relaxed!"

Seeing this, the servants of the Yanwang Mansion all stopped crying one by one, and their eyes were wide open to watch this scene. "King Yan is really amazing!" "King Yan's divine power is world-shattering!" "King Yan is the overlord of the world!"

After stopping crying, there was another burst of touting.

The people who watched nearby, and even some knelt down to worship.

And when the ministers saw this, they were also shocked.

"How is this possible!" Daru Gao Qi said.

"Alright, Di'er, you can put it down." Zhu Yuanzhang said.

"The retainers obey." As soon as Zhu Di let go of his hand, the person dodged out, and with a loud bang, Da Ding fell heavily to the ground.

"Di'er, how the hell did you do that?" Zhu Yuanzhang asked, he had already seen at this time that the key was on the rope and a few pulleys.

"Even if the father doesn't ask, the son will explain it to everyone." Zhu Di stood in place, like a teacher, and popularized science to everyone at the scene, "Fellow villagers, my lords, in fact, it's not my Zhu Di's natural divine power, which can lift a two-thousand-pound tripod." The key to my ability to lift the big tripod is the rope and the pulleys hanging in it. ”

"As we all know, when we get water from the well, there is a wheel at the top, which is also called a pulley. However, it is a fixed pulley, and the fixed pulley does not save effort, but once the pulley is moved into a movable pulley, one can save half of the force...... A fixed pulley and a movable pulley form a pulley group, which not only saves effort but also changes the direction of force. ”

"This method is the principle of movable pulley, and it is also taught to me by Mr. Qin, which is the most superficial physics."

A movable pulley can save half the effort!? The crowd was shocked.

If they could use this method in the future, wouldn't they be able to lift heavy objects with ease?

"His Royal Highness King Yan, can you let the old minister try it." An Ren, the secretary of the Ministry of Works, stepped forward and said.

"Master Shan, please!" Zhu Di said.

Shan Anren stepped forward, grabbed the rope and pulled it hard, and sure enough, he easily pulled up Dading, and became excited: "Great, great!" With this skill taught by Yanwang, it will be much easier for the Ministry of Engineering to construct in the future. ”

"The old minister is a craftsman for the world, thank His Royal Highness King Yan." After speaking, he bowed deeply to Zhu Di.

The Ministry of Industry is responsible for the world's repairs, works, salt ponds, gardens, and water conservancy matters, half of which are major projects. Large-scale projects basically use heavy materials, and if they are simply lifted by manpower, it is not only time-consuming and labor-intensive, but also very dangerous.

Zhu Di's invention can be said to have saved the lives of many craftsmen.

In the past, due to the limitation of manpower, tens of thousands of catties of materials could not be lifted even if there were more people, resulting in some engineering buildings being directly rejected by the Ministry of Industry. If they could use pulley block technology, they could build more magnificent buildings.

Shan Anren's head spun rapidly: the direction of force could be changed with a pulley block, and it would be more convenient to use a chariot to pull the rope underneath...... Then this chariot plus pulleys can be called a 'crane truck'!

immediately turned his head to Zhu Yuanzhang and said: "Your Majesty, this invention of His Royal Highness King Yan has made the world's projects simpler. Many water conservancy projects that could not be done before can also be launched. Therefore, His Royal Highness King Yan's invention is beneficial to the country and the people, and it will be recorded in history, please give your majesty a reward. ”

"Of course we'll give you a reward." Zhu Yuanzhang was full of relieved smiles, "Zhu Di! ”

"The son is here."

"We'll reward you with one hundred taels of gold and five thousand pieces of silk!" Zhu Yuanzhang turned his head to the representative of the scholars, and the great Confucian said, "You scholars, you have read so many sage books and opened your mouth to be the words of a sage, have you ever done such an initiative to benefit the country and the people?" ”

Gao Qi was speechless.

"Thank you, Father!" Zhu Di was in high spirits.

……

"Your Majesty, it's not good, Xu Miaojin broke into the military department and proposed that he wanted to discuss military affairs with the generals of the military department on the sand table." At this time, a eunuch hurriedly came to report to Zhu Yuanzhang.

"She's a woman, and she actually went to the military department to make trouble? Monkey business! Zhu Yuanzhang frowned, "Pass the decree and let her leave quickly." ”

Xu Miaojin is Xu Da's daughter, except for Shangshu Chen Liang, all of them are Xu Da's old subordinates, so she broke in, and no one in the military department dared to stop her, and even treated her very respectfully.

"Your Majesty, the queen is also here." The eunuch said, "The queen seems to be very supportive of Xu Miaojin and fighting with them. ”

"Then forget it." Zhu Yuanzhang said.

Suddenly, Xu Miaojin began to show his military talent? Could it be that Mr. Qin wants to train her to be a talent like Sun Bin and Bai Qi? He wants to train a female general for Daming?

No wonder the girl attaches so much importance to it and goes there in person!

Now the general situation can be seen, the king of Shu will be Lu Buwei in the future, Xu Miaojin will be the daughter of Sun Bin, and the princess of Ningguo may be the first female champion of the Ming Dynasty in the future, the king of Yan...... I can't see it yet, but I have also made great contributions to the Ming Dynasty and the people of the world.

This Mr. Qin is really terrifying!

After teaching so many talents at once, they have only learned from him for less than ten years, and they all began to show their edge.

Shine brightly, and show your edge!

The young generation of Daming has many talents, all of whom were taught by Mr. Qin.

"Let's not go over this matter in person, whatever they do." Zhu Yuanzhang said that he planned to give Queen Ma a face and let her deal with it. Xu Miaojin is the minister's daughter, and Queen Ma is barely a politician in her affairs.
