Rebirth of Zhu Di's son

Chapter 90
After the three people retreated.

Zhu Gaoxu sat quietly in the study for a moment, thinking about tomorrow's itinerary.

After a while, he felt a little stuffy, so he raised his head and looked towards the corridor entrance on the right side of the study. He saw Kang Ping, who was sweating profusely, waving a cattail leaf fan and instructing several servants to turn the handle hard and drive the fan machine to create a cool breeze. .

"Kang Ping, come here."

Zhu Gaoxu called Kang Ping to the table and asked: "The Ministry of Industry has made a simple spring chain device out of fine steel, why not replace it with a new combination fan cart?"

At present, the fan wheel used by Kangping's chamberlain is a relatively traditional vertical fan in history. Its shape is similar to that of a spinning wheel, but its size is larger than that of a spinning wheel, hence the name fan wheel.

The structure of this fan truck is relatively simple. It is equivalent to installing a rotating shaft on a bracket. Five or six long wood chips are embedded on the rotating shaft and spread out radially to form a circle of fan blades. A crank is connected to each side of the rotating shaft. As long as you hold the handle with your hands and keep turning it, it will drive the rotating shaft, causing the wooden fan blades to rotate continuously, causing the air to flow and forming a cool breeze.

The "new combination fan cart" Zhu Gaoxu mentioned uses an elastic metal chain to coil seven hand-operated fans on a long shaft, and then one person pulls the running device at the end of the elastic chain, which can be used by tightening and loosening it. The elasticity of the metal chain allows the seven-sided fans to rotate simultaneously, creating a cool breeze throughout the room.

The new combination fan truck greatly saves labor costs, improves the efficiency of artificial cooling, and is many times less noisy than the traditional fan truck.

Zhu Gaoxu asked this question when he saw that Kang Ping was sweating profusely from exhaustion.

"Your Highness, your Majesty, I did go to the Ministry of Works two days ago to pick up a new fan cart." Kang Ping said respectfully.

Zhu Gaoxu asked coldly: "Why not?"

Kang Ping knelt down and said, "Your Highness, please, my slave—"

"Go and receive ten strokes of the cane, and then come and report!"

Zhu Gaoxu interrupted Kang Ping mercilessly and punished Kang Ping in an unquestionable tone.

"Slaves take orders!"

Kang Ping kowtowed, then retreated and received ten strokes of the cane.

Zhu Gaoxu listened to Kang Ping's howling outside, and sat on the chair with an expressionless expression, waiting quietly.

Not long after, Kang Ping, who had received ten strokes of the cane, walked in unsteadily and knelt down again five steps away from Zhu Gaoxu's desk.

He touched his head to the ground and said in a trembling voice: "Your Highness, please, when I went to the Ministry of Industry to get a new fan cart, I saw that Wenyuan Pavilion sent two new fan carts with stuck chains. I was afraid of the new fan carts. It malfunctioned during use and made His Highness unhappy, so he took the initiative to put it into the warehouse without using it."

"Do you know where you went wrong?"

Zhu Gaoxu looked down at Kang Ping with a majestic look on his face and asked coldly.

Upon hearing this, Kang Ping knew that Zhu Gaoxu had forgiven him, and immediately responded respectfully: "This slave should not put the new fan cart into the warehouse without using it."

"Go and receive ten strokes of the cane. If you still can't figure out what's wrong, you don't have to think about it anymore!"

Zhu Gaoxu frowned.

Kang Ping suddenly remembered that under Zhu Gaoxu's humble and kind appearance, he hid his military experience of leading troops in battle, charging into battle, and killing Tartars.
In other words, the prince he served was the same as his current majesty. He seemed to be kind and gentle, but in his heart he was ruthless, decisive and arbitrary. He hated his subordinates acting without authority.

"This slave will receive your punishment."

After Kang Ping figured it out, he bowed and retreated again to receive the cane punishment.

In Zhu Gaoxu's view, since Kang Ping was his childhood companion, he took the decision without permission this time and did not use the new fan carriage. Next time, he might give orders for him without permission on the grounds of "for the sake of His Highness the Crown Prince."

And this is absolutely prohibited by him!

In addition, there is another important reason.If Kang Ping received the new fan cart and never used it, it would likely delay Zhu Gaoxu's discovery of the shortcomings of the new fan cart.

This will naturally delay Zhu Gaoxu's intention to improve the fan car through the Ministry of Industry, thereby improving the practicality of the elastic metal chain in equipment.

If the Ministry of Industry solves the problem of the stuck elastic metal chain of the new fan truck, it will inevitably conduct a series of research on the braking, stopping, control strength, wear prevention, and maintenance of the elastic metal chain.

If the Ministry of Industry has matured research on elastic chains, it will naturally use its elastic power to improve other equipment, which will further improve the application experience of elastic chains in equipment.

Given time, Zhu Gaoxu could order the Ministry of Industry to combine the elastic metal chain with the escapement used in the water transport instrument platform of the Song Dynasty, and then create a mechanical clock after experiments!

Once the mechanical clock came out, its positive impact on the military, economy, education and other aspects of the Ming Dynasty can not be summarized in a few words.

In other words, Kang Ping's well-intentioned usurpation of power is likely to delay the advent of the Ming Dynasty mechanical clock. How can Zhu Gaoxu not be angry?
After a while.

Kang Ping bowed to the study again and knelt down again.

He kowtowed first, then bowed his head and said respectfully: "Your Highness, this servant made the mistake of not taking the fan cart into the warehouse without authorization. Instead, he had to strictly follow His Highness's order to take the fan cart back and use it normally. Only Your Highness can decide to use the fan cart." The power or not. It is the duty of a slave to work for His Highness, and a slave should not monopolize power."

Zhu Gaoxu said "hmm" first, and then said: "This is a small punishment as a warning."

The implication of his words is that Kang Ping should take a warning when dealing with this matter, and there will be no next time.

If Kang Ping does not have a long memory and commits the crime again in the future, Zhu Gaoxu will not kill Kang Ping, but he will definitely send him away.

"My slave, I thank you for your grace!"

Kang Ping said with great respect.

He had been tortured with a cane twenty times. Logically speaking, he should have been excruciatingly painful. However, everyone in the palace knew that he was His Highness the Prince's childhood companion and was now His Highness's confidant. How could he dare to do something harsh?

Zhu Gaoxu took another look at the traditional fan car in the corridor on the right, and couldn't help but feel a little helpless.

As the saying goes, "A nine-story tower rises from tired soil." The improvement of a country's scientific and technological level is never achieved overnight.

"Go and pass on my instructions and tell the Ministry of Industry to start improving the chain device of the new combined fan cart. If you can build the improved fan cart before the end of the month, you will be rewarded heavily!"

Zhu Gaoxu felt a little uncomfortable when he thought that his mother, Queen Xu, Wang Qihong and their two children were still suffering from the noise of the traditional fan.

He and Zhu Di were both rough-skinned and thick-skinned men. They could tolerate noise and get through it, but women and children could not tolerate it.

Moreover, according to what he knew in his previous life, noise can affect the development of babies.

Of course, Zhu Gaoxu knew that it was also possible to use an ordinary cattail leaf fan to extract wind manually, but he still hoped that Queen Xu and others could use the advanced new fan machine as soon as possible.

"Remember, the sooner the better! Let the skilled craftsmen of the Ministry of Industry take turns to study for twelve hours, and we must improve the new fan machine as soon as possible, and strive to let my mother use the new fan machine with low noise and fewer faults as soon as possible! Do you understand me?"

Zhu Gaoxu felt that for the Ministry of Industry, only when there was pressure would there be motivation, so he decided to let the skilled craftsmen of the Ministry of Industry work hard all night to achieve results as soon as possible.

"My servant heard clearly. Your Highness, don't worry. I will go to the Ministry of Works to convey the message."

Kang Ping kowtowed, then bowed, endured the pain in his buttocks, and stepped back quickly.

Zhu Gaoxu looked at the three sentences covering tomorrow's plan on the paper on his desk, and then he added a fourth sentence at the end - "Inventing things, focusing on talents."
