"If the clear and turbid are not distinguished, the Song Dynasty will be in danger! If the corrupt officials are not eliminated, the Song Dynasty will be in danger!"

"Guangyan Road! Reduce taxes! Suppress mergers!"

Zhao Xingde stood by the wall, listening with his ears in his ears, and the noisy sound could be heard.&&After a while, the parade gradually became far away and the quiet outside the wall was restored. Zhao Xingde sighed and sat down. From Ezhou, to various prefectures and counties, to the royal family, the prime minister, to the common people, were all churning in this oil pan at this time. Although the mansion of Wuchang Hou was quiet, he could also feel the blazing temperature outside.

The rights of the great etiquette law, the prime minister, the six ministries, prefectures and counties and ordinary scholars are clearly written, and it is precisely so that every aspect does its best to use their rights. The unproper parts of the great etiquette discussion are suddenly exposed. For example, the rights of scholars to discuss, march, and are fully utilized by the students in various places. Once the yamen intervenes, they will be detained for the crime of slandering and even intend to rebel.

According to Zhao Huan, the Ezhou business is still good. In some places, Qingliu is in power and imposes severe punishments on the people of the people, which makes it difficult for Qingliu to be the gentry, the wealthy families are suffering and even flee to other places. In other places, the gentry maintains the government and uses the Qingliu method to deal with the people of the Qingliu. A large number of Qingliu scholars who have committed minor crimes are brought to prison and punish a small number of death row prisoners sent to Ezhou. Armed battles broke out among the people in other places, with as many as 10,000 participants. The local government did not dare to call local regiments, so they could only ask the court to transfer official troops from foreign counties to suppress the rebellion.

In the chaotic current situation, the Wuchang Hou Mansion was stagnant. Zhao Xingde had to work hard every day, but he could only read his writing and chat with Zhao Huan from time to time to relieve his boredom. In addition to writing articles about the "Gentleman's Way", he drew out some mechanical patterns he remembered in his previous life, bound the articles and patterns into books in a category. He also made various small models according to his understanding of current technology, and calculated and inferred various parameters. Zhao Huan was most afraid of what he had to do. Seeing Zhao Xingde use this to relieve his feelings, he not only did not think that he was not doing his job properly, but instead summoned various craftsmen to accompany him in an interest.

At this time, the stone table in front of Zhao Xingde was flat with a square rectangular wooden board, flat white paper, and a boat was painted with four or five masts, various square or triangular sails of all sizes, and gun windows were opened on both sides of the hull.-In the vertical section of the middle of the hull, there was a huge cabin at the bottom of the ship, which was installed like an upside-down bamboo dragonfly. Next to the largest drawing, there were also drawings for various purposes such as the hull contour.

"What is this?" Zhao Huan held his cuff and pointed curiously at the bamboo dragonfly-like thing.

"Rolling." Zhao Xingde explained, "Some people call it "propeller". I think "rotating" is more appropriate. It is always under the water, and its working style is more like a slalom. In traditional places where there are no slaloms, it is called a trouser shirt, trouser legs and cuffs tied with ropes, and one is drawn from a stack of patterns. This picture is an enlarged picture of the structure of the propeller components. There are hundreds of boarding pedals in the bottom cabin. The two rows of "rotating" mounted on the bottom of the ship are rotated through the gear set and the slender screws.

"Hey, I feel like I'm putting down the wheels on both sides of the car and ship and putting them on the stern of the boat." Zhao Huan gestured in circles with both hands, pressed them on the side of the hull, and said in confusion: "Then the wheels will be bigger, so there will be no more." After seeing all the strange things Zhao Xingde drew, she went to the Ministry of Works to find patterns for reference, which made her a lot of insight.

"In that case, the paddles will waste a lot of effort when entering and exiting the water." Zhao Xingde pointed to rows of square grids on both sides of the hull and explained, "And gun windows must be arranged on both sides of the hull." He pointed to the mast and sailing path. "Sea boats mainly rely on wind power, but when there is no wind or war, the warships will have much better power if they have their own power. For example, the vehicles and boats in Shu and the galloping and sailing ships in Western Yi are all like this."

Huan thought something and then smiled, "If the navy had such a warship, it would be able to drive out the pirates."

"Just talk about it in vain." Zhao Xingde shook his head, "It can't be created without the experiment."

Huan nodded. She had a deep understanding of what Zhao Xingde said about "experiment".

As for the hull, Zhao Xingde first used the sea ships in Song and Western Yi sea ships he had seen as references to make wooden models. Through the comparison experiments in flowing water, he believed that the sea ships in Song were better. With this experiment as the foundation, he specially chose some related to the center of gravity of the hull, the center of the hull, the displacement, and the dimension parameters of the outer contour of the ship, to calculate the resistance, the buoyancy, and the resistant performance of the two ship types in the water. Finally, based on the sea ships in Song, it optimized its size, and finally made a wooden model according to this size. Compared with the original model, it was obviously much better. After learning that the pirates of Dashi invaded the coast, Zhao Xingde handed the optimized sea ship model to the Ministry of War together with the size ratio.

In addition, because ordinary wooden boats could not bear the power of the cannon, Zhao Xingde considered using an iron-bone floating box to build a gunship. The keels, hull ribs, and even the longitudinal truss beams under several layers of decks were all cast iron to form a mesh iron-shaped iron-bone ship frame, covering the iron bones with thick wooden boards to form the hull profile. Important components such as artillery gun mounts, masts, rudders, and rudders are also connected to the iron bones. The cabins are all floating box structures of different shapes. The floating boxes are fixed to the iron bones, and even if some cabins are penetrated and leaked, it will not cause the sea ship to sink immediately. However, there are many other improvements in this iron-bone floating box ship because it cannot be carried out for reliable experiments, and just like the placement of this "rodders", it only exists in the drawings.

Zhao Huan could not hand over these strange things to the Ministry of War with Zhao Xingde on his back. Just as she didn't believe that small "rotary oars" could replace the big "wheels", but she would not argue about it. While helping to collect the patterns, she said casually: "The patterns given to the Ministry of War were handed over to the shipbuilding business. The shipbuilding business said that they only control the shipbuilding yard. In fact, the shipbuilding yard was in charge of the shipbuilding department, and then transferred the patterns to the transport department. Later, there was no result. The Ministry of Justice is now strictly investigating the iron nail case. The Transporting Department has been imprisoned for more than 20 officials, and everyone else is in danger. They probably don't care about the new shipbuilding example."

Xingde's face was not disappointed, but instead asked, "Iron Nail Case?"

"Well. The official in Nanhai reported that the construction of official ships in Jianghuai is easy to break, and it is difficult to resist the strong storms in the South China Sea. It is recommended that the official ship yard be set up in the South China Sea after that, and all ships in the South China Sea are built locally by Guangnan Road or Nanhai. Mr. Chen sent this message to the Transportation Department to ask the Transportation Department to discuss whether it is feasible? As a result, the JAC ship yard was very opposed and insisted that the JAC ship had been in the South China Sea for more than a hundred years and had never had any problems. The official in Nanhai was purely a matter of nothing. The two sides had a relationship of writing and ink, and Mr. Chen sent the Censor Xu Xiaoyun to Jianghuai to find out who is right and who is wrong. However, the Censor Xu was a disciple of Wu Shang."

Zhao Xingde's face showed a strange look, and Zhao Huan explained: "When Mr. Chen sent him there, no one else said anything."

"So that's it." Zhao Xingde nodded, with appreciation in his eyes. Zhao Huan's pink cheeks were slightly red, and he smiled and said, "The corrupt officials in the boat yard prepared everything for the materials and manual books. They thought they were smart, and they all chose to defend themselves. If there is no real evidence, they could not torture them. Who knew that this Yushi Xu, like his mentor, was an absolute madman. I heard that he actually started with the most difficult iron nails to check. But I can't understand why the iron nails on the boat are the most difficult to check. Do you know?"

Zhao Huan kept silent and looked at Zhao Xingde with a smile, as if he was going to take the exam. After entering the mansion for a long time, the couple was not like a couple, and friends were not like friends. After getting along for a long time, she gradually let go of her mind and was not so restricted by Zhao Xingde, but became casual. I don’t know when she called her “husband” and gradually became a habit.

"I have seen the iron nails of sea boats when I was in Liaodong, which are indeed the most difficult to check." Zhao Xingde explained, "Iron is most likely to rust when subjected to moisture. Not only will the iron nails rust, but it will also erode the surrounding wooden boards, causing the wood to form hollows. Over time, the ship will be destroyed. Therefore, when building ships, in order to prevent the iron nails from rusting, craftsmen not only have to knock the iron nails into the wooden boards together, but also use putty material to add lumps to fill the nail holes, and cover them all with concave holes to seal them. Therefore, once the sea boat is built, it is extremely difficult to check the length of the nails."

"So that's it," Zhao Huan smiled slightly, "I asked several people, but I didn't know what was going on. My husband was more knowledgeable. In this way, the way Xu Jingshi's approach made sense. After he arrived in Jianghuai, he first asked the account books for materials used in various shipyards, and then asked the major shipyards to send a new newly built ship to Hangzhou Prefecture, and then a fire burned all the new ships of all sizes."

"Ah?" Zhao Xingde frowned and listened to Zhao Huan continue: "Xu Jingshi reported a shipyard to each yard, and the iron material used for ships had already been piled up next to it. He dug out the iron material from the burned skeleton, which was less than half the weight it should have. It is said that at that time, the officials of the major yards of Jianghuai were frightened. Xu Xiaoyun sacrificed the Qingliu Law on the spot and took down all the officials in the yard. That night, the court impeached the court and asked the Ministry of Justice to investigate the case. Later, the Ministry of Justice followed up on the case, jailed and interrogated the relevant people, and investigated many other corruption matters. However, among the students in the southeast prefectures and counties, Xu Jingshi's official voice suddenly rose."
