The information in Zhao Bing's hands is very limited now. In addition to a model of a water mill and a picture of a Western cow pulling paddle wheel in his mind that may be a fake. The car and ship are ready-made, but he feels that the hull structure still has many imperfections and needs further improvement. Therefore, it is still a very exhausting job to complete the idea of ​​driving the car and ship in the animal power, and it may just fill the spiritual emptiness.

Zhao Bing felt that it was not the most difficult to design the power source. From that picture, there were three pairs of cows on the top open-air deck, that is, six cows were pulling three pairs of paddle wheels. But he knew that for warships, the top deck was generally a platform for soldiers to fight, and warriors were needed to be arranged and combat weapons were installed. Therefore, when Zu Chongzhi designed the Thousand Mile Boat, the winch should be moved to the next deck to free up space on the top deck for combat needs.

At the same time, Zhao Bing thought that rotating a pair of paddle wheels with animal power was not only very slow, but also the circumference of the winch required a large circumference of the moving space. A deck could not be as dense as accommodating sailors. If a double-layer winch was used, and livestock were arranged on both the upper deck and the lower deck, it would take up more unprecedented amounts. This caused a contradiction, which required redesign and optimization.

When choosing livestock, it also needs to be carefully considered. The magic book "The Heavenly Gong Kaiwu" recorded by Zhao Bing records: Any powerful cow attacks two stones in a day, and a donkey is half a piece. The strong attacks three dou, and the weak is half a piece. This means that the cow has the greatest strength and the longest sustainability. Based on this ratio, a cow can be used by about seven people. But the weakness is obvious. One is slow speed and the other is large in size. Eating more is second, and the space occupied is also large.

Zhao Bing looked through the information of the vehicles and ships that the Song army had equipped. During the Yue Fei pacified the Yangyao Uprising, the largest vehicle was 36 zhang long and 4 zhang wide. The official ruler of the Song Dynasty was about 31 centimeters, with a length of about 110 meters and a width of about 12 meters. The load capacity was 5,000 stone. At least 150 people needed to be stepped on by the cattle. However, in actual combat, there were few wooden ships more than 100 meters. Generally, large vehicles were between 20 and 30 meters. He decided to design them based on this basis, which could be used for combat, or to quickly mobilize troops and transport supplies.

In addition, Zhao Bing found that the ancients had misunderstandings in the use of paddle wheels, thinking that the more paddle wheels, the more power, and the faster the corresponding speed would be. Therefore, not only ten cars, fifteen cars, but also as many as thirty and forty cars. He thought that from the perspective of product manufacturing, large ships needed large paddle wheels to push. In addition to pursuing efficiency, it was also conducive to reducing the components of the ship and making it easier to repair. However, if forty cars were eighty small paddle wheels, the paddle wheels were small in size and large in number, which would be easy to damage.

In addition, if it is forty cars with forty paddle wheels on each side, the boat must be very long. According to the records, only a large ship with a height of more than thirty feet is possible. In addition to the inconvenience of paddle wheels due to the arc and anchor chains, winchs, rudders, etc., the length of the paddle wheels that can be placed is estimated to be around twenty-five meters. The space allocated to each paddle wheel is more than six feet. Subtracting the wheel spacing, it is estimated that the diameter of each paddle wheel is five feet long, while a paddle wheel with a diameter of five feet is too small for a ship with a diameter of more than 100 meters.

In addition, because the paddle wheel is a paddle that is efficient and continuously moving, the too dense wheel spacing will reduce the effectiveness of each wheel, which means that many paddle wheels are just filling in the numbers. Because the paddle wheel in front rotates fast and the water flows fast, the paddle wheel behind does not need to do much work. The water flow is sometimes faster than the paddle wheel behind. Therefore, the paddle wheel spacing cannot accelerate the ship, but instead affects the speed of the ship. The paddle wheels are counteracted with each other. Unless the paddle wheel behind is always faster than the paddle wheel in front, it will not be counteracted.

It can be seen from this that the ancients had inappropriate design views of forty cars with 80 wing wheels. In addition, the rudders of vehicles and ships were mostly designed on the virtual tank, with the tail rudder placed under it and located at the end of the virtual tank. This suspension method increases the load of the rudder, and a four-zone long oar weighs more than 700 kilograms, let alone the rudder? If the weight of the large car suspended at the stern, the rudders on the virtual tank are easily broken during high-speed navigation in water battles due to the tearing torque generated by the huge resistance of the rudder.

Because at this time the rudder is not only affected by the resistance of the water flowing back when the hull advances, which is the resistance of all rudders; it is also affected by the high-speed backward water flow when the stern car rotates. This water flow impacts the rudder rod and rudder surface at a high speed. This is the resistance unique to the rudder with the stern car. These two forces act on the rudder placed at the end of the virtual tank, which is likely to tear the wooden components of the rudder, that is, after the stern car, installing the rudder will cause self-damage to the vehicle and the ship...

Zhao Bing listed the difficulties encountered in the improvement one by one, and then solved them one by one from difficult to easy. However, this process is not easy. It often has to be overturned and re-designed because of a small data error. Of course, the most difficult part is the power source. For this reason, he also sent people to find a few cows and made a simple winch for actual measurement.

In this way, the soldiers in the garden also found fun. They were also idle and uncomfortable in addition to training, duty and cleaning on the island every day. The little emperor not only asked them to measure the shoulder height, weight and length of each cow, but also asked them to pull the winch and drag different heavy objects in circles. They wanted to record the durability of the cows at different speeds, etc., and of course they had to serve their food and drink well. Each data must be accurate and recorded.

However, Zhao Bing was not idle either. He was considering how to maximize the effect of each paddle wheel at constant speed. First, he selected the size of the paddle wheel and wanted to make the paddle wheel at the back equivalent by adjusting the angle or number of blades on each paddle wheel. However, he found that this was too cumbersome, so he thought that each set of paddle wheels could be connected in series through the transmission mechanism, so that all paddle wheels could be driven through two sets of winches, which could also reduce the space occupied by livestock. In addition, using a variable diameter worm can achieve the result of different rotation speeds at constant speed.

After solving the transmission problem, new problems also emerged. Using the tail rudder to control the direction can easily cause damage to the hull, while without the rudder, it has become a problem of choosing one of two, but it is indispensable. Zhao Bing suddenly thought of modern tanks one day. We know that the steering of the tank does not change the driving direction with the front wheel guide like a car, but relies on track difference, that is, the track on one side is fast, and the track on the other side is slow, and the track difference causes the tank to turn.

The formation of track difference is caused by cutting off part of the power of one side of the track and increasing the speed of the track on the other side. This is called separate steering, which is used for fast and small angle steering, and the steering method adopted when moving. Or completely cut off the power, brake one side of the track and the other side of the track, which forms one side of the track does not rotate and the other side of the track is called in-situ steering, which is used for slow and large angle steering, which is the steering method adopted when starting or stopping.

Zhao Bing thinks this idea is feasible. Just by using a switching mechanism, the paddle wheels on both sides of the vehicle can achieve different speeds and steering, that is, the speed difference steering. As for the large-angle slow steering, he retained the single paddle wheel at the stern, and used this to maintain the power of the ship to advance, and then cut off the power on one side to achieve large-angle steering.

One problem was solved, but another problem arose. The car and ship can use the front and rear treadmills of humans to achieve both advance and retreat. However, the cattle are not as good as the humans, and it can be replaced with the lower legs, but the cattle needs to re-fit the shaft to achieve it, which will inevitably delay a lot of time. However, it is not so easy for Zhao Bing to study it with manpower. The car and ship often drive at both ends, so it seems that there must be a rudder on the bow and stern.

Besides, if the rudder is installed at both ends, it will inevitably affect the waterline structure of the bow of the hull and the speed of the ship. At the same time, it will also squeeze the narrow cabin space with the anchor chain winch, increase the complexity of the sailors on the ship, and reduce the overall combat effectiveness of the ship. Fast forward and backward are of practical significance in actual combat, and Zhao Bing believes that it still needs to be retained.

The problems are accumulated and different solutions are needed. Zhao Bing thinks that this is too complicated. It not only increases the difficulty of operation and maintenance, but also requires the number of operators. The method of simplifying the complexity requires the collection of all functions in one place. So the world's first transmission appeared, which can realize the ship's advance, backward, and turn, and has three forward gears to complete all operations during the ship's operation.

After obtaining experimental data and conception, Zhao Bing spent five days drawing the drawings, and then made a 1:100 model in five days, and used clockwork as power to conduct a trial sail, verifying the feasibility of using animal power as the power source. Then, the model production of the gear shifting mechanism and connecting rod mechanism began. At this time, he thought that this was the most difficult part, and the entire mechanism was made of metal, but the current metal material performance was not stable, but he had to try to ensure the normal operation of the entire linkage mechanism in design.

After countless adjustments and solution optimizations, Zhao Bing completed the manufacturing of the model. In order to ensure the durability of the entire mechanism and the accuracy and smooth operation, he felt that there was little room for further improvement under the current technical conditions, so he finally determined the drawings. In addition, in order to ensure the strength of the ship, he also used a large number of metal parts, especially the keel, which used a large number of forging parts.

Zhao Bing knew very well that it would cost tens of thousands of yuan to test the production of a large warship. Once it failed, a large amount of manpower and financial resources would be wasted. So he did not dare to be careless, so he invited several masters from the yard to explain them one by one, so that they could understand and figure it out. This was why they were asked to conduct the trial production and told them if there were any problems, they must tell themselves and never change them without authorization.

After a month, Zhao Bing completed the drawings and model design of the animal carriages and ships, but he was a little confused about why the "Thousand Mile Ship" of the vehicles and ships that were widely used in the Song Dynasty did not appear, which itself did not conform to the laws of historical development. He estimated that it may be because of the long-term lack of horses in the Song Dynasty, which restricted the development of animal carriages in the Song Dynasty. In the meantime, my country's horse carriage development may lag behind the West, but it made the vehicle, which relied entirely on manpower, prosper. It can be said that the prosperous vehicles and ships did not develop, but instead led to the stagnation of technological innovation and a certain degree of regression...

Zhao Bing worked hard for a month and improved the chariots and ships. However, the court was cold. Yao Liangchen and Wei Tianzhong were dismissed from office and seized their posts after being tried by the Three Departments, and all fame and fortune were removed. Yao Liangchen was assigned to the Huguang Xingye Office, and Wei Tianzhong was assigned to the Gaozhou Office. The families of both sides were expelled from Lin'an and sent to their original hometown for custody. The descendants were not allowed to participate in the imperial examinations for three generations.

At the same time, the Empress Dowager issued an order to appoint Cai Wanyi as the prefect of Lin'an, Chen Zeweng as the Minister of Revenue, and Qi Yaqing as the Minister of Works. Deng Wenyuan took over as the Minister of Justice and appointed Pan Fang as the Minister of Maritime War. From the appointment, Zhao Bing could certainly see that these people who entered the ranks of prime ministers were all his own teams, and it can be seen that the Empress Dowager was deliberately eliminating those who had dissent for himself and arranged his confidant into important departments in the court.

According to secret reports from the palace, the empress dowager had aroused his intention to kill Chen Yizhong. He thought that when the young emperor was still the King of Wei, Chen Yizhong repeatedly harmed him. He had just recovered Jiangnan, so he framed the young emperor to dismiss him, and even sent him to assassinate him in the hall at this moment. Therefore, Chen Yizhong was alive and had endless troubles, and he would inevitably rebel again. It would be better to execute him to death and eliminate future troubles forever.

Zhao Bing was moved, and also knew that it was almost impossible to eradicate the rebels. Because as early as the fall of Lin'an ten years ago, the emperor had already determined that the Song Dynasty had been destroyed when he was hunting north, so he said that it was restored, but in fact it was no different from re-establishing a country. People felt that a child who only occupied a corner of Qiongzhou could re-establish a country and become an emperor. In this way, it was not difficult to be an emperor. As long as you have strong strength, you can achieve it. There are also success, kings and defeats. As long as you succeed, you are the emperor. No one will say that your throne is wrong.

Although most of Jiangnan is recovering now, people want to fight for the world, but their hearts to be emperors have not calmed down, and they still want to rebel. As long as they rebel, they can achieve their goals. Let’s look at why there are so many dynasties during the Southern and Northern Dynasties, that is, everyone wants to rebel, and the possibility of success is relatively high. For example, when Chen Sheng and Wu Guang of the Qin Dynasty rebelled, the world flocked, and everyone wants to have the authority of Qin Shihuang. However, because an idiot in the Western Jin Dynasty became the emperor, everyone wants to rebel.

You can imagine that everyone thinks that no matter how I am an emperor, a bastard and a fool. Nowadays, there are also people who think that being an emperor is better than a child, so Zhao Bing feels that he is more dangerous than when he was in Qiongzhou...
