"For example, when I am in the palace, I have to spend half an hour memorizing the book every morning and then half an hour to visit each palace to greet you. If I memorize the book first and then to greet you, it will take an hour in total. If I memorize the book on the way to greet you, and when my greetings are over, the book will be almost finished, and it will take only half an hour to put it together."

"This is the simplest project coordination." Zhu Cixuan explained: "I mentioned the flat car and wheel rails to the front, and arranged trial production of different types of Sugang steel and the construction of gantry crane models. It is precisely because the human resources required by these three can be spread out in parallel.

"After solving the problem of fit between Taiping Car and wooden rails, the different types of Sugang Steel should also achieve something, and it just happened to test the steel rails. Using the experimental data of the different types of Sugang Steel can also provide material support for the construction of gantry cranes.

"When the rail trial production is successful, the gantry crane should also be installed, which just solves the problems of large-scale unloading and transportation of goods. Finally, the purpose of improving loading and unloading efficiency and saving manpower is achieved."

Coordination is an interdisciplinary between mathematics and social sciences, complex and sophisticated. Zhu Cixuan's team in his previous life had specialized talents responsible for this area, which belongs to a highly professional field. However, once the requirements are lowered, even if there is only the conceptual idea of ​​coordination, it will be much better than just a single eyebrow and beard.

In this magical era of late Ming Dynasty, Eastern and Western cultures collided and blended like never before. The scholars and officials were not as stubborn and xenophobic as written in textbooks. It was just that because of the different nature and social environment, the intellectual elites had different focus. Once someone pierced the layer of paper, the scholars and craftsmen of the Ming Dynasty would burst out with amazing creativity.

From Franc to Lumi guns, although they are all foreign objects, the Ming Dynasty can quickly imitate and improve it to make its performance better than the original objects. This is the solid productivity at work, so Zhu Cixuan sometimes feels that what the Ming Dynasty lacks is not technology, but ideas.

As long as you have a proper idea, you can ignite three thousand years of accumulation and explode an unprecedented spark of civilization.

"If it is not a project that directly affects our army's combat capabilities, I hope to try my best to use this time-saving coordination model." Zhu Cixuan said: "Now we have sufficient money and materials, and what we lack the most is time and manpower."

"Your Highness." Wang Zheng came back to his senses from this concept of coordination. "The theory of coordination is indeed unique. It is better to open a new course of coordination to broaden the eyes of the people."

"I may not be able to start classes recently." Zhu Cixuan was really unable to do anything. After thinking about it, he said: "In this way, I will write a booklet as soon as possible, just like to make a splash. If I want to study this coordinatedly, I am afraid that it will take several generations to do it."

Wang Zheng nodded slightly, and he really admired the prince who came out of the deep palace. Not only could he see what others could not see, but he also had the patience to accommodate a hundred years of wasted time. It was really a blessing for the emperor. When this meeting happened, how could he not do his best to do his best?

"My minister Song Yingxing asked to see His Highness the Crown Prince!"

A sudden call for a lookout came from outside the house.

Zhu Cilang was really surprised and happy when he heard this. He couldn't help but push the door out in two steps. He saw an old man in his sixties, pressing his gray hair and pressing his hands on the shoulders of two tall guards. He jumped up and visited the room from between them.

If he hadn't been wearing the official uniform of a fifth-rank civil servant, the two guards would have already slashed on them.

"Is it Song Fengxin who wrote "The Work of Heaven"?!" Zhu Cixuan shouted loudly and walked down a step.

"Your Highness!" Song Yingxing shouted: "It is the empress! I respect the new Song Yingxing!"

"I have written several letters to you, why have you never seen you reply?" Zhu Cilang was overjoyed and hurriedly stepped forward and separated the left and right guards, holding Song Yingxing's arms.

Song Yingxing looked stunned: "Your Highness only needs a letter of order, and the empress will naturally go north to Shenjing to pay homage to His Highness."

How could Zhu Cixuan have an affair with the ministers at that time? And it was because of such "strange skills and lewd skills". If his father, who was obsessed with classics, would he not even be able to do small physics experiments in the palace in the future. What's more, a prince who had never left the palace, summoned an insignificant teacher in a county in Jiangxi, how should he explain to the Ministry of Personnel and the emperor? Could it be that he dreamed of it?

"After I received the book "The Work of Heaven" I admired Mr. Jiangxi many times and wrote letters to him. But I never received a reply." Zhu Cixuan did not say that he was anonymous, but Wang Zheng, who came out, knew the inside story and was confused.

In Wang Zheng's opinion: as long as you have insights in studying matters, even if you are a common man in a white body, this Mr. Song will travel thousands of miles to a while.

"Uh... When did Your Highness get this book?" Song Yingxing was stunned.

"I just got out of the box in the spring of the eleventh year of Chongzhen and found that there were people selling this book on the market, so I bought one." Zhu Cixuan said.

"Oh..." Song Yingxing dragged his voice long, feeling quite regretful: "This book was engraved in the early tenth year of Chongzhen. Your Highness got this book in the spring of the eleventh year. It can be said that the Weishi's luck." Song Yingxing paused and said: "It's just... In the eleventh year of Chongzhen, Weishi's re-elected the Tingzhou Promotion Officer in Fujian, and he has left Fenyi."

Song Yingxing was just a teacher without grade in Fenyi. Zhu Cixuan used a private message sent by Jingzhongjiao. Naturally, the foot delivery would not be chased to Fujian, and Jiangxi could not travel thousands of miles to curry favor with a small official. So Zhu Cixuan's letters were like stones sinking to the sea, and he even doubted whether this naturalist was still alive.

I really didn't expect that I actually met it in Laizhou!

"The old minister also read "The Art of Heaven" and was amazed. Later, he learned that Brother Song had arrived in Laizhou and specially invited him to be a professor." Wang Zheng also walked down the steps and said to Zhu Cilang with a smile.

Zhu Cilang was really smiling: "It's God's will! Today, no one can compare to Mr. Wang by learning theories of the East and the West; no one can surpass Mr. Song by learning theories of the past and the present! There are two gentlemen in charge of supervising, so why worry about not having a powerful weapon to restore the world!"

"Your Highness." Song Yingxing also came back to his senses from the greetings and pulled out a roll of paper from his sleeve: "Your Highness! I am going to present a weapon to restore the Shenjing!"

"Oh!" Zhu Cixuan took the paper roll and spread it out in the light. He found that it was a long scroll, which was depicted on it with a "divine weapon" that exceeded Zhu Cixuan's imagination.

"This is the flying weapon that I have drawn by Your Highness!" Song Yingxingchao, who had stopped him before, made a move: "Why are you so blind? Let Your Highness hold it up?"

The two guards didn't know whether they should listen to the orders of this crazy old man. Lu Suyao and Min Ziruo, who were following Zhu Cilang, had already stepped forward and divided the left and right to decide for Zhu Cilang.

"Please look at your highness!" Song Yingxing took out another magnifying glass with exquisite workmanship and silver-handled gilded frame from his sleeve, pointing to the picture: "This is an airbag, with the outer layer wrapped in silk, the inner layer lined with cotton cloth, and the heat is ignited below to lift the hanging basket into the air. Everything is like a Kongming lantern."

"This...is a little different..." Zhu Cilan stared at the diagram, feeling dry.

The development of the hot air balloon was specially taken care of by Wang Zheng alone and promoted it as soon as possible. The purpose was to strengthen the viewing distance on the plains and detect the advancement of large enemy troops as soon as possible.

What Song Yingxing said is indeed the basic principle of hot air balloon lifting off.

However, what is drawn on this drawing is not just an airbag with a hanging basket.

It's simply a pod!

"This hanging basket should be able to carry five people," said Song Yingxing. "If you want to move forward after you take off, you must control the wind, so I added sails around this hanging basket."

Zhu Cilang saw that the mast of the sail was pierced diagonally above, and no matter which direction the wind came, he could use force to push it.

If this were the case, Zhu Cilang would not have been shocked and his mouth was dry.

"What if you want to go against the wind? Or turn in the air, what should you do?" Zhu Cixuan asked.

"Then it depends on these small cannons." Song Yingxing pointed to a circle of black protrusions outside the hanging basket.

Zhu Cilang's heart trembled: It's indeed a cannon!

"Your Highness's book also said that force has positive and negative forces, and its power is mutually reunited. Look at the military cannons, and it is indeed pushing the cannons backwards when they are fired, and their power is very great! I want to use gunpowder to push the spaceship against the wind." Song Yingxing smiled and said, "I think wind and water are similar, and the hanging basket should be a ship shape, just like walking in water, or it may have miraculous effects."

"Ahem," Zhu Cixuan cleared his throat again, "Your idea is very good. But this airship...Ahem, the same is true for the spaceship. When flying in the sky, the wind is endless, and gunpowder is just an impact force and cannot last. How to solve this problem?"

Song Yingxing had obviously thought for a long time and said bluntly: "What I think of now is to use anchoring the wind, and wait until the wind stops before urging the steering with gunpowder."

"Why not use a bellows?" Wang Zheng looked aside and suddenly said.

"The officials also thought about it." Song Yingxing said: "It's just that the hanging basket is small and the load is limited, so it can only be blown by manpower. This wind is probably not enough to make the spaceship go against the wind."

"Um..." Wang Zheng pondered: "I thought I could use the wind."

"Wind?" Song Yingxing passed by: "Are you adding a group of windmills in front and back? The car in front is driven by the wind and drives the lever shaft, and the car in the back is blowing and running?"

"That's right!" Wang Zhengdao.

"Old sir... hahaha!" Song Yingxing suddenly laughed: "If you add a turntable under the pod, place the wind-powered bellows on the turntable and respond with the wind, wouldn't this be especially good?"

"Not bad." Wang Zheng nodded repeatedly: "I'm afraid this thing is too heavy and cannot fly."

"It's okay, you can increase the air chamber and stove to create heat with a strong fire." Song Yingxing gestured on the drawing: "If there is insufficient airbag, it can create five, and be arranged in plum blossom style... Well, the hot air duct of the stove must also be divided into five strands and sent into it..."

Zhu Cilang was excluded unknowingly and said to himself: I just want a hot air balloon. It would be fine if you get me a hot air boat, but now you have to be an air fortress? Even if I am really too MSI, the emperor's grandson, God will not give me face to let this thing fly! (To be continued...)
