It is precisely because of the incomplete reform that although the good and low-in-law marriage in the Song Dynasty was not static, it was basically inherited. Not only did the "Song Zhengtong" promulgated in the early Song Dynasty copy all the provisions on "Tang Law Commentary" about good and low-in-law marriage, but the law was still the same until the late Southern Song Dynasty. In other words, families of all levels could only intermarry with families of the same level. As for the fact that the scholars and commoners did not marry, they were only general. The marriages within the family were still handled by the elders, which was consistent throughout the feudal era in China, and the Song Dynasty had no changes.

Therefore, Zhao Bing still did not have much hope for his marriage, but he still hoped that he could interfere. In his opinion, although marriage cannot be decided by itself, but exists as a political tool, he needs to use it to the extreme. He knew that in order to prevent foreign relatives from interfering in politics, the basic principle of the Song Dynasty was to "raising them with a rich fortune and high title, and not letting them take power and act without any responsibilities."

That is, although the court would grant false titles such as foreign relatives and military governors, they would not give them real power. Among the many foreign relatives, there were only a handful of officials who were powerful ministers. Therefore, from the history of the Song Dynasty, there were not only no foreign relatives and foreign ministers at that time, but foreign relatives could hardly have much impact on the government affairs. In such a social environment, many foreign relatives developed the habit of being indifferent to power, and they were therefore praised as "obtaining the foreign relatives' body."

Zhao Bing wanted to use the principle of "no foreign family holds important positions and does not interfere in political affairs" to eliminate those important officials in the court who want to change, but cannot withdraw, but cannot leave. He can use a marriage to send them home for retirement, and then gradually promote his confidants to the throne, so that they can't fight bloodshed, and naturally complete the transfer of power and the peaceful transition between new and old ministers. But in the current situation, it is difficult to do it because there is no initiative in this matter.

Since there was no way to change, Zhao Bing temporarily left the matter. However, the empress dowager put Yao Liangchen and Wei Tianzhong in prison, which made him feel strange. Was he establishing authority for the sake of mastery or eliminating disasters for himself? But after careful consideration, it was not very similar. According to historical rules, before the young emperor took office, he was a big marriage, indicating that he was an adult, could handle government affairs and manage state affairs.

On the other hand, Zhao Bing considered that the Zhao family had undergone a great transformation and the population was withered, and there were only a few left in the royal family. The descendants of Emperor Ningzong were only himself and Emperor Deyou, Zhao Xian, who was far away in the capital. As far as he knew, he later married a Mongolian princess and became a monk in order to avoid disaster. His descendants wanted to recognize their ancestors and return to their hometowns, and they might not be able to make it into the score because their bloodline was impure. The task of scattering the branches and leaves was given to him. Even if he died, he could leave a man and half a woman, so he could have a root and inherit the great throne and not fall into the family.

However, when Zhao Bing thought of this, he was relieved. At that moment, the Song Dynasty left him a true master. Even if the Empress Dowager wanted to govern the court and live in the recreation of becoming Wu Zetian, the throne would have to be passed on to him sooner or later. If he had an external intention, then someone would write to the Empress Dowager to let him take charge of the government and send him back to the harem. But according to what he saw, the Empress Dowager was not a person who was greedy for power, and things would not reach that point, but he could not guess the hidden truths of it, and he did not want to guess...

Although Zhao Bing made up his mind to stop thinking about affairs in the court and had a few days of leisure, he wandered around this mountain with a big butt in less than two days. He had no literary and artistic cells, and could not express his emotions when he saw the scenery and recited poems and essays. Every day, except following the military soldiers from the guard camp to practice martial arts, he would find a place to catch fish and shrimps by the lake, but he would never think about going down the island to stroll elsewhere.

Now behind Zhao Bing is not only the guards of the Guards, but also the guards of the Guards. Yang Shilong also gathered all the ships on the island in the name of strengthening vigilance, and ordered a regiment of soldiers to strengthen patrol day and night to prevent anyone from smuggling to the island. Of course, he knew that these were measures against him, but he was too lazy to be angry with him. Chen Dun was so angry that he wanted to mobilize the Guards to destroy the first regiment, which clearly saw them as thieves!

"The water wheel is designed very exquisitely!" The Huangting Hall in Yanxiang Garden is a multi-story building that overlooks the entire West Lake area. It is the most important main building in the park and has the best landscape. The hall is also painted with landscape paintings by Xiao Zhao, a famous painter of the dynasty. Zhao Bing climbed the tower to see the scenery today, but did not see what the scenery of West Lake is good. In his eyes, the natural landscape without artificial decoration is the most magnificent. The telescope couldn't help but turn to the farther field. At this time, summer grain is about to be harvested. The farmers are using the water wheel to drain the excess people in the paddy fields. He looked at it and said with a smile.

"The official family is not called a water wheel, but a water mill. It is very common in Jiangnan near the riverside. It is said that it was invented by Zu Chong of the Southern Dynasty. Even the emperors at that time saw it personally. This thing can be used in one fell swoop, one part of the water rotating wheel head, one part of the milling into the surface, two part of the milling into rice, and three part of the milling water is used to irrigate into the rice fields. People around the water have families with water milling, but they will never use rice husks to husks for the rest of their lives." Wang De explained with a smile.

"Oh, it turns out that this thing is a water mill!" Zhao Bing touched his chin and said. He remembered a debate on the Internet in his previous life, which was about whether the water mill invented by Zu Chongzhi was related to the "Thousand Mile Boat".

"Yes, this thing in the official family is very clever. We can go and take a look in the future!" Wang De has been with the little emperor for so many years, so he naturally knows what he likes and said with a smile.

"Wang De, go back to the palace and ask the craftsmen in the craftsman to make a model of a water mill, and move the objects in the studio here." Zhao Bing had his own thoughts, thought of a goal that could pass the time, and turned his head to Wang De and said.

"The empress dowager has an imperial edict, and she will not be allowed to return to the palace without an edict. Besides, Commander Yang is very strict in his guards, so it is not easy to go out!" Wang De said with a difficult face.

"Idiot, then you let him send a message. I will want these things tomorrow, let him take care of them!" Zhao Bing cursed, then turned around and left.

The next morning, as Zhao Bing said, Yang Shilong personally sent what he wanted to the bedroom and kept apologizing. He said that the empress dowager had scolded him fiercely yesterday, scolding him for not understanding his own feelings and asking him to take good care of the little emperor, but how dare he be unreasonable to His Majesty. At the same time, he said that as long as His Majesty did not go down to the island to ask for anything, he would not dare to disobey anyone who wanted to meet him.

Zhao Bing naturally would not care about it because of this. His mind is no longer here. Now everyone knows that the reason why the car and ship must be faster than ordinary wooden oar warships. The first is to analyze from the perspective of human muscle strength. There is a saying that "the arm cannot twist the thigh". From the difference in the strength of the legs and arms, we can see that the car and ship must be faster than the paddle boat. The second is that from the perspective of physical work efficiency, the paddle blades of the car and ship are continuous and have high efficiency, while the wooden oars are resting and have low efficiency.

Therefore, theoretically speaking, sailors of the same number and the same physique drive ships of the same tonnage with paddles and paddle wheels, and sail in the same waters, the speed of paddle wheels is basically twice that of paddle boats. Of course, the situation in actual operation will change due to other factors, but it is certain that the maximum speed of the vehicle and ship should be higher than the fastest paddle boats.

Vehicles and ships appeared very early in Chinese history, and at least during the Southern and Northern Dynasties, it was widely used. And at this time, a Mengchong warship called the "Thousand Mile Ship" suddenly began. Zhao Bing certainly knew that the power sources of ancient ships were only sails, manpower, and power propulsion tools, that is, oars, waterwheel paddle wheels, etc. But from the name of the "Thousand Mile Ship", this high-speed ship is likely to have used a new power source or a new power propulsion method.

Since the Thousand Mile Boat has no physical objects or pictures left, according to historical records, it can be seen that it is an inland river warship. Zhao Bing and others determined that because the inland river and near-shore warships require high maneuverability and cannot be affected by the wind direction and water flow, the sails are not the primary source of power for the warships. From a physical point of view, there is no room for improvement in the work efficiency of holding the oar and oar. Therefore, based on the historical conditions at that time, they judged that the possible improvement was to add an efficient driving force or a paddle-wheel propulsion device that was better than the current warship waterwheel.

Due to the lack of historical materials, people later did not know who invented it, so they had many speculations, thinking that it was invented by Zu Chongzhi. But later generations knew that he was a mathematician and calculated the pi, thinking that this was something that was nothing special. This led to a lot of controversy.

Zhao Bing "studyed" for a while and thought it was really possible. Zu Chongzhi lived in the Liu Song and Southern Qi dynasties. His grandfather Zu Chang was once the master craftsman of Liu Song and was in charge of civil engineering. Zu Chongzhi's father also served as an official in the court. With such a family environment, coupled with his acquired efforts, he made great achievements in mathematics, astronomy, calendar, and mechanical manufacturing. In addition, he had successfully copied the guide car and the water mill, it can also be inferred that Zu Chongzhi had a very profound study of the vehicle and gear structure.

However, Zhao Bing's views were severely criticized, thinking that this was a matter of no connection between cattle and horse. Opponents believed that the development and innovation of technology were not completed overnight, and they were both historically inherited. However, the Tang, Song and Ming dynasties, which had extremely developed ships and ships, did not have the so-called ships traveling thousands of miles a day, and the Song Dynasty, where vehicles and ships were most widely used, did not reach this level. So how did it appear during the Southern and Northern Dynasties?

Zhao Bing was speechless at that time, but some people put forward new ideas, thinking that it was not labor-intensive and not because of Feng Shui, so it could only be animal power. Using animal power as the power of the ship usually occurs when pulling fibers. In addition, there is only another situation left - a cow has been turned on a car and ship in the West. The evidence is that in the world's first painting of a cow pulling paddle ship in the sixth century AD, a cow was used to push the winch on a Roman warship, and then the winch gear drove three pairs of paddle wheels on the side of the ship.

However, some people on the opposing side soon said that this painting was a fake work of later generations, not from the sixth-century painters. Because before this picture, there were no documentary records of vehicles and ships in the West. For a long time, until the Da Vinci era, the vehicles and ships he envisioned were only drawing plans rather than physical objects, and there were no records of vehicles and ships in the West, which made this picture look extremely abrupt. Moreover, the vehicles and ships in the picture were still using the original side rudder rather than the stern rudder, but the power system was the top paddle wheel propulsion device in ancient society, which made people doubt its authenticity.

The water mill has long been lost, and it is something that only heard the name but is not detailed. Zhao Bing can't come up with anything favorable to prove it, so he can only be "willing to give up the disadvantage". However, the water mill has revelated the past. Anyway, it is idle. It is worth it if it can prove that his original argument was correct. Although those netizens don't know it anymore, let them go in a mess! And now I have thought it through, and it is of practical significance to be able to restore such high-speed vehicles and ships. Why not do it!

Zhao Bing now first studied the principle of the water pestle mill. Before the water pestle mill appeared, the grinding and the grinding were separated, and it was rotated by human or animal power for a long time. Zu Chongzhi's invention was to use the "water rotation" wheel axle to promote the "grinding". Then the first digit like Zu Chongzhi calculated the pi value to the seventh decimal place, created the "Da Ming Calendar", invented the timer, especially the great scientist who copied the guide truck that drove copper-made machinery, was very likely to implant the animal power rotation and grinding into the ship's power system, and it was possible to reverse the reversal of the shipbuilding, and use "grinding" to promote the "water rotation" and realize the energy conversion.

At the same time, the machinery invented by Zu Chongzhi was not improved on the basis of his predecessors, but was created based on the name of his predecessors. Therefore, the Thousand Mile Ship is also likely to be a new fast-speed vehicle improved on the Mengchong warship in the late Eastern Jin Dynasty. Perhaps the Thousand Mile Ship is named after a ship driven by a Thousand Mile Horse, because we rarely say that a ship travels a thousand miles a day. Apart from this Thousand Mile Ship, there are only the Thousand Mile Ship of the Song Dynasty that the flying tiger warships of the Tigers travel a thousand miles a day, but Zhao Bing has seen it, and he thinks it is impossible, and he has not found a livestock ship.

Zhao Bing felt that the idea of ​​replacing human power with animal power is not impossible to achieve, and it is of great practical value. The Yangtze River defense line is long. Even if he deploys a large number of troops on this line, it is still far apart. If a war occurs, it is necessary to increase troops in time. The fastest and most effective way is to go on the water route. It is better to go down the flow and maintain a faster speed. It can be traced upwards. If it is against the wind or the river flows quickly, the boating speed will decrease.
