Zhao Bing knew that with the changes in the situation between the Song and Mongolian countries, wars would become more and more frequent, and the more affected areas would be more and more. He even faced several battlefields at the same time. He could not fight in person as before. Now the army has been rectified and expanded many times, and the middle and senior officers have been eliminated in continuous actual combat and learning, and the rest have all grown into generals who can stand alone. They are familiar with the use and marshalling of firearms and can independently command army and division-scale battles.

But what made Zhao Bing worried was that after capturing Jiangnan, Song and Meng only broke out some local battles, which were short and mostly small-scale battles at division and regiment level. Although military-level exercises are held every year to train troops and be familiar with the synthetic command of various types of troops, he still has no idea.

Today, Zhao Bing suddenly wanted to "steal" horses, not only to solve the problem of lack of war horses, but also to test the troops' actual combat capabilities and commander level. Although the First Marine Division is under the command of various departments of the Navy, he has always used them as fast-response troops. Therefore, the Marine Corps is the unit with the highest combat readiness and fastest reaction speed among all armies.

Furthermore, the Marine Corps, as one of the naval combat forces of the naval army, also shoulders the functions of landing and seizing important places. It can be said that it has the advantages of both water and infantry. This requires them to be familiar with the two types of combat methods of water and infantry, and the commanders must also have the command ability of a combined military branch. Today's battle happens to be a joint combat between various military branches. Even if the scale is small, it can be tested for the actual combat command ability.

In addition, from a political perspective, peace between the Song and Yuan dynasties, even if it was short, was not in line with the interests of the Song Dynasty. This not only would be the slackness of the military and civilians, but also would also make some groups feel lucky and have the idea of ​​sitting in a corner. Only constant wars can keep the court and the country alert, knowing that the war is not far away, so that they dare not have the intention to neglect it.

The goal, purpose and direction of the battle are now clear. Zhao Bing granted Zheng Yi full authority to command, which can mobilize the forces of various troops. He and the generals are just bystanders and will not interfere with their command without extraordinary circumstances. The result he wants is that he must see the war horses appear on Chongming Island tomorrow. As for the process and what tactics they use, they will not ask about it.

Zheng Yi was suddenly ordered, and the pressure was imaginable, but he also knew that the Holy Order was difficult. After receiving the order, he did not dare to neglect it. He immediately summoned his staff to formulate a more detailed combat plan. He knew that the key to winning the battle was to be fast, so he should not use too much troops. After several discussions, he decided to organize a marine regiment, a cavalry regiment, a naval transport detachment and two baggage battalions into a synthetic brigade. In order to facilitate the collection of horses, he also dispatched a squadron of the Imperial Horse Battalion to assist.

Time was tight, and Zheng Yi immediately submitted a memorial after the combat plan was formulated. Zhao Bing knew that a good combat plan meant that the battle had been won. After reviewing it, he issued military talismans to mobilize the troops and launch an action. After Zheng Yi was authorized, he did not dare to neglect it, and immediately ordered the generals to announce an edict, issue combat orders, issue tasks, and carry out pre-war preparations. After dark, all the troops entered the combat position...

The battle to seize the horse has begun, but Zhao Bing became the manager of the hand. In order to ensure his safety, he returned to the imperial ship to spend the night under the persuasion of the generals. Although he said he was delegating power, he was still worried and couldn't sleep, so he went to the deck again. At this time, the lights had been lit on the imperial ship, reflecting the bright moon in the air, and waves were shining on the river surface, and everything was exposed to the moonlight. In theory, this was not the best time to smuggle.

However, Zhao Bing was not worried. There were many ways to solve this problem. The smuggling troops could swim by swimming, or send water ghosts to cross the river to clear the posts, or take advantage of the fog of the river as a cover to complete a small-scale smuggling. He saw that the island was also busy now, and the supplies camp responsible for building bridges quietly transported the required materials to the river bank with the help of the protection of the woods, and once they received the order, they could be deployed immediately.

‘Bang, bang…’ At this time, a rhythmic knocking sound attracted Zhao Bing’s attention again. He looked down and found that a group of sailors on the boat gathered on the river to wash clothes. The sound was the sound of the hammer hitting the clothes.

The army requires the military to be clean and the clothes should naturally be cleaned regularly. The Sheji is the emperor's boat, so sailors must pay more attention. However, the weather is hot now, and they are not active, and their clothes are full of sweat and smell. Moreover, they have to run boats and sails. Their bodies are wet and wet, and they can only wash clothes every day and keep them clean.

But Zhao Bing knew that from ancient times to the present, washing clothes was a housework that was difficult to escape. The most beautiful description of washing clothes was "Xi Shi washing yarn". When the beautiful Xi Shi was washing yarn by the river, the fish forgot to swim and sink to the bottom of the river when she saw her reflection, so Xi Shi had the synonym for "sinking fish". But the reality is that before the appearance of washing machines, for many people, it was not as fun as described in pastoral poetry.

Nowadays, these sailors use the power of the river to wash clothes with their hands and the impact of sticks. It can be seen how time-consuming and laborious physical labor is to wash clothes at this time. Hand rub, stick hit, erode, and slam... These repeated simple physical labor often leave people with the feeling of being: hard work.

It is said that the pounding pestle was invented by people living by the water for the convenience of washing, while those living far away from the water invented the washboard. The pounding pestle is made of wood and has a similar shape to a baseball bat. It relies on the power of the pounding pestle to make clothes and uses water to bring out the dirt. In order to clean it, some cleaning agents are often added.

Modern people know that to wash clothes, water, agitation and surfactant are needed. The dust sticks to the fibers and rinses with water, you can rinse it clean, but in order to clean up the yellow stains on the collar, you need to use surfactant to deal with it. Surfactant is a compound, and the molecules that make it look a bit like extremely small magnetic particles. One pole of this "magnetic particle" molecule attracts dust, and the other pole is attracted by water. The pole of the vacuum-sucking absorbs the oil of the clothes, the pole of the water makes the oil loose from the cotton fabric and hangs it up, and then rub it hard, and the dust will be washed away.

Naturally, there were no chemical synthetic agents such as laundry detergents widely used in later generations. However, Zhao Bing knew that there were substitutes in this era, and the most common one was wood ash, because the potassium carbonate in wood ash could remove oil stains. In order to make the silk soft and white, the ancients wet the silk with wood ash water, put it in the ash made of shells, and soak it in water to react, producing a strong alkali - potassium hydroxide.

Generally, the dirty substances on clothes are mainly oils, and most of the oils are oils. Under alkaline conditions, the degree of hydrolysis intensifies, resulting in high-grade fatty acid salts and glycerols that are easily soluble in water. The main components of wood ash are strong alkali and weak acid salts, and their aqueous solution is alkaline due to the hydrolysis of carbonate ions. In addition, during this period, in addition to wood ash, people also used animal oil, vegetable oil, soap beans, and alkali salts to clean clothes. At present, the most popular thing in Lin'an City is the "soap ball", which uses soap powder to make orange-sized round balls, and put them in water to foam and remove dirt. He thought that the name of soap in later generations may have been inherited from this.

With surfactants such as water and wood ash, people's clothes are much cleaner, but washing clothes is very hard whether they use pounding and scrubbing or rubbing with their hands. Is there any effort-saving way to wash clothes? Yes. Zhao Bing knew that these sailors did not always use pounding and pounding to clean clothes on weekdays, but they would also be "lazy". During the boat sailing, they stuffed dirty clothes into a cloth bag, tied them to the boat with one end of the rope, and threw the cloth bag into the sea. During the sailing, they let the water flow stir, pat the clothes, and the clothes were washed.

Thinking of this, Zhao Bing suddenly had an idea. Westerners were inspired by the "sea laundry". In the 17th century, someone invented a washing device, which used a device composed of wheels and cylinders to squeeze the water flow and imitate the effect of washing the sea. This device is the prototype of modern laundry machinery. So why can't he "invent" one and liberate the people of the Song Dynasty from this labor?

Once Zhao Bing had this idea in his mind, he couldn't sit still. He didn't have anything to do with him and couldn't sleep well. It would be better to just have a washing machine to play with it. On a whim, he did it as soon as he said he could do it. He immediately came to the studio on the boat. First, he tried his best to recall the development history of washing machines in the world so that he could learn from it.

As Zhao Bing knows, the first washing machine was born in the United States in the 19th century. Its main part is a round barrel, which contains a straight shaft with paddle-shaped leaves, and the shaft rotates by shaking and cranking it. However, this washing machine is laborious and damaged clothes, so it is not widely used, but this marks the beginning of washing machine with machine laundry. Later, a washing machine with a pounding pestle as a mixer appeared in Germany. When the pounding pestle was stirred, wooden nails equipped with springs were continuously hitting the clothes.

By the end of the 19th century, the washing machine had developed into an octagonal washing machine that rotated with a handle. When washing, hot soapy water was placed in the tank, and the clothes could be squeezed into the clothes after washing. Then the Americans invented a wooden hand-crank washing machine, which had a very simple structure, which was to install six blades in the wooden tube and drive it with handles and gears to flip the clothes in the tube, thereby achieving the purpose of washing.

Later, steam washing machines appeared in the United States, and steam power began to replace manpower, greatly reducing people's physical labor. France has appeared steam washing buckets that are small, easy to carry and suitable for housewives. Steam washing machines have made a qualitative leap in efficiency compared to hand washing. In various steam laundry shops on the streets and alleys, steam washing machines are used handily, and laundry shops have also flourished.

Afterwards, hydraulic washing machines and internal combustion engine washing machines also appeared one after another. Hydraulic washing machines are an upgraded version of "Sea Laundry" and are set on the boat. The washing machine has inlet and outlet holes, a power source on the shell, and a clothes inlet hole on the washing tube. Its import is equipped with a sealing cover. The washing machine is connected to the boat through a connecting piece. It only requires natural river water to wash clothes, and it is much cleaner than "Sea Laundry".

As for the subsequent electric washing machine, he was no longer considered by Zhao Bing. He could design it himself, but he could only stay on paper, which could not be achieved under the existing conditions. In his memory, several sketches of manual washing machines from various periods had been drawn on paper. After several comparisons, he felt unsatisfied. He was either too "backward" or the laundry effect was not good.

"Why am I so stupid?" After thinking for a moment, Zhao Bing suddenly slapped his head and murmured. He was so stubborn that he was in a stubborn state. When he was a child in his previous life, the most advanced one was the large-pull twin-cylinder washing machine. It was improved and the best design was obtained after several improvements. It was not eliminated until the fully automatic washing machine was put into use on a large scale.

At present, he doesn't have to consider timing, water saving and other issues. He just designs based on its mechanical structure and changes power to manpower operations. Thinking of this, Zhao Bing immediately started designing it. After discarding the messy multi-functions, the main body of the washing machine is a square wooden barrel and a large pulsator. This is a piece of cake for him, and it doesn't even require detailed drawings to create it.

However, Zhao Bing considered the reality, he still separated the washing bucket and the dry bucket and adopted a split design. He originally planned to adopt a more durable gear transmission structure, replaced it with belt transmission, and changed manual drive to foot-stepping drive. This not only facilitates manufacturing, reduces costs, but also saves more effort, and is also conducive to promotion.

"Your Majesty, the first land warfare regiment has successfully smuggled. The Navy Transportation Detachment also used the tactic of direct rushing to the beach to send the cavalry brigade directly to the beach. It has been launched now!" Tan Fei came in and reported.

"Road directly to the beach!" Zhao Bing frowned and said in surprise. He was not surprised by the successful smuggling of the Marines from the front, but he felt that it was inappropriate to use a transport ship to directly to the beach to transport the landing troops. This not only changed the combat plan previously formulated, but also the warships directly grabbed the beach without the help of modern power machinery, and it was almost impossible to retreat back to the sea. This is different from losing watermelons and picking sesame seeds.

"Your Majesty, is there anything wrong?" Seeing that the little emperor's expression was wrong, Tan Fei was a little nervous and asked hurriedly.

"Oh, nothing. Go and ask the craftsmen on the boat to wait for me on the deck!" Zhao Bing thought for a moment and waved his hand, and ordered. At this time, he had figured it out and understood Zheng Yi's intention. He was to use the characteristics of flat sand boats to directly rush to the beach in shallows, so that it would not damage the hull. Then, using the opportunity of high tide to get rid of the beach and return to the sea. It can be said that this is not only a very smart approach, but also to promote this tactic in various departments.
