Three Kingdoms.

  Chapter 2405 New Technology

   Plague does not distinguish between men, women, young and old, nor east, west, north, south, east, west, but this thing likes chaos, and the more chaotic and disorderly it is, the better it will spread.

  Cao Jun also showed the symptoms of the plague here, and some soldiers fell ill and died. However, the difference from the chaos in Jiangdong is that when Man Chong discovered this problem, he took out the "cheat sheet".

  『Clear all feces and urine around the camp! Zhang Tunchang, this matter is entrusted to you, and I will give you fifty civilians. It must be cleaned up today! 』

  Tun Zhang Zhang accepted the order with a sad face. This job is the dirtiest and most tiring, but it is a military order that cannot be ignored.

  『Leader Li, I will give you fifty civilians to go to the county town to recruit and burn mirage. At least five vehicles must be paid within three days! One less car only you are asking! 』

   Mirage is quicklime.

   It is not an easy job to do this thing. Fortunately, Xiapi and Guangling are close to the sea, otherwise it would not be easy to make shells all of a sudden. Although he knew it was not easy, Captain Li could only take orders.

  Other jobs are actually not easy.

  『From today onwards, all civil servants form teams, select team rates, and implement continuous sitting! 』

  『The corpses of the dead should be burned and buried without delay! 』

  『Dead fish, shrimp, rats, and many other dead things are not to be eaten! 』

  『Dig out the canals in the shed area and bring running water in! All houses and sheds start from the downwind place, so let's get rid of it! 』

  『A new sick camp was opened, another hut was built, mirage was laid, and fences were set up! 』

  『The clothing and utensils of those who died of illness shall be burned and buried! 』

Man Chong explained one by one, then his eyes drooped slightly, he landed on the table, checked it again, and found that there was nothing wrong, so he said in a deep voice: "Everyone perform their duties and work together, this plague , Immortal! go! 』

All the generals and schools in the large tent of the Chinese army responded with a bang, and then they went out to take action one after another. There was a burst of people shouting and screaming in the camp, but it didn't appear to be chaotic. On the contrary, under the leadership of the generals and schools at all levels, they gradually started into an orderly process.

   Man Chong exhaled slowly.

  He didn't expect to encounter the plague either.

  But Manchong's advantage is the "cheat sheet" in front of him, a copy of the relevant regulations about the Guanzhong Sanfu's response to the Tongguan Plague and the shelter of refugees from Guo Jia.

The symptoms of the plague are actually not difficult to distinguish. Vomiting and diarrhea can cause death quickly and are contagious, so it can basically be judged to be a plague. Although Man Chong is not clear, no one will even figure out these plagues for a long time Where did it come from, and why did it spread, but it did not prevent Man Chong from making countermeasures based on this "cheat sheet".

  At present, the most important thing in the face of the plague is not to save people, but to defend. Because of the limited and rudimentary medical environment, it is impossible to treat infected patients at all. The only effective measure is to establish an isolation zone, like opening a bare isolation zone in the mountain forest. Even if a certain area is burned, As long as the fire does not spread to other places, it is fine. In the end, as long as the fire in the burned place is slowly extinguished, the fire will pass.

  This method is somewhat helpless, but it is also the best coping strategy at the moment.

You only need to give people or refugees a certain amount of food, and these people and refugees will not catch those rats or eat those dead things, thereby reducing the chance of infection from the plague, and avoiding the scope of continued illness continued to expand.

  A complete set of "cheat sheets" for gathering refugees, disaster relief and prevention, in fact, each of them is concise and to the point. Guo Jia deliberately brought it out of Guanzhong Sanfu, and then got a backup from the political upper circle around Cao Cao...

In fact, before Guo Jia’s cheat sheet, Lao Cao’s classmate had some references to the various health regulations in the Hussars. There were really no “health regulations” these days, not only ordinary people, but even the children of the gentry. exception. Even in the Jin Dynasty, didn't many gentry children take it as elegant to catch lice with their chests exposed even after they smashed the five stone powder?

At first, including Man Chong, many children of the gentry did not take these things seriously, and they did not think that these "cheat sheets" had any practical value. However, the matter of the refugees in Jingzhou was indeed on the faces of the Cao family and Man Chong. He slapped loudly.

  Especially Cao Zhen. He came back covering his face.

  It was from that time that Cao Jun paid attention to implementing these health regulations.

   For the same reason, Man Chong and other talents pay special attention to these "cheat sheets" for epidemic prevention and control, and even carry them with them...

  『Hussars...』Man Chong slowly touched the cheat sheets spread out on the table, then grunted something from his throat, which eventually became a soft sigh.

  …(д)…

  Between Qing and Xu, when the plague spread, Fei Qian took a group of his men to the Xuanwu Pool outside Chang'an City to inspect the latest ship construction.

   In ancient times, if you wanted to transport well, wheels and legs were indispensable.

  Run on the ground with four legs, while the boat floats on the water with wheels.

  For Fei Qian, cavalry is very important in order to control a huge area, but the navy is equally important, and the core of the navy is the ship.

  Different ships, different sails, different technical requirements, and different channel adaptations.

  Before Fei Qian, Dahan’s ship requirements were large and complete, complete and beautiful.

  In other words, until the Ming Dynasty, the guiding ideology of ship manufacturing was still the same.

   Small ones are easy to flip, so make big ones.

  The wind power of a single mast is small, then install three, if not five, nine...

  舸, boat, flat boat, canoe, boat, boat, Ge boat, bridge boat, 艨艟, fighting boat, building boat!

   It seems that there are many, but in fact the technical content or the difference in varieties is not very big, and some are simply the difference between a smaller size or a larger size.

  The history of Huaxia shipbuilding was already on a large scale even before the former Qin Dynasty.

  Because after Qin Shihuang used force to end the hundreds of years of feudal Chuhou melee since the Spring and Autumn and Warring States period, in order to consolidate the rule and deter the remaining old aristocratic forces of the six countries, Qin Shihuang began to tour the territory of the Great Qin. During Qin Shihuang's fifth inspection tour, he brought a huge parade team to Yunmeng Daze. After worshiping Yu Shun at Jiuyi Mountain, he floated down the river, passed Danyang, arrived at Qiantang, crossed Qiantang River, and went up Kuaiji Mountain, offering sacrifices to Xia Yu, then returning to Wudi, and then sailing northward by sea boat, sailing north along the eastern coast of Qin State to Langye, is the earliest large-scale national coastal cruise.

   Later, Qin Shihuang's parade team landed at Zhifu, where they carved stones to record their achievements. This was Qin Shihuang's last tour. He changed from car to boat along the way, from inland rivers to sailing, and it took several months.

   It is conceivable that if there was no emperor fleet with complete navigation equipment and good navigation performance, Qin Shihuang would not have been able to conduct multiple long-term cruises in the rivers, lakes and seas, let alone cruise on the sea.

  Of course, in fact, during Qin Shihuang’s eastward tour, some of them wanted to obtain the so-called "elixir" of the sea gods, which was driving...

  After all, most of the land was conquered by Qin Shihuang at that time, and the only thing that had not been controlled by Qin Shihuang was the sea.

   It's a pity that Qin Shihuang waited until his soul was gone, but he still didn't wait for the news of the fairy mountain in the East China Sea.

In fact, at that time, if Qin Shihuang, like Fei Qian, claimed that he was not claiming personal immortality and longevity, but that there were mountains of gold and silver in the East China Sea, countless gold and silver everywhere, and rivers of precious stones, there would have been ships of the Great Qin Empire long ago. Set foot on Yamatai.

  The time when Huaxia clearly set foot in the "East China Sea" was earlier than many ordinary people in later generations believed. Chen Shou of the Jin Dynasty used a considerable amount of space in "Three Kingdoms" to introduce some situations of the Eastern Japanese. It shows that at least during the period of the Three Kingdoms, they have already gone to sea and landed in Dongbo.

   Moreover, Sun Quan may have used the sea from the riverboat...

  Fei Qian is currently in Xuanwu Pond, the main purpose is to point out some technology trees of the ship first, and then build a transportation hub that runs through the east, west, north, south.

  After all, in the pre-Qin period, there were nine ways to go. It makes no sense that the Han Dynasty, which lasted for three or four hundred years, degenerated instead.

  The previous flywheel was just the legs that Feiqian put on the ship, but now the triangular sail will become the brand new wings of the ship.

  In this era when there was no steam engine foundation, it is self-evident how important sails are to a ship. It can even be said that when the triangle sail is hung on the mast of the ship, the technology tree of the wind sailing ship is basically outlined as a whole, and the rest is supplemented with some details.

  It is very windy today.

  The wind is strong to facilitate testing, but although it is generally regarded as a southerly wind, I don’t know whether it is because of the Qinling Mountains or other factors that cause the southerly wind direction, but it is a bit erratic, and it is difficult to ensure a specific direction.

   This caused great trouble to the navigation of the ship.

  However, this is closer to the actual situation. After all, anything can happen on rivers, lakes and seas.

  The new type of ship is a big ship with three masts, a big four-corner sail, and two big triangle sails.

  The building boat built by Ma Jun before used horizontal sails.

  The horizontal and vertical here does not depend on the horizontal and vertical of the sail, but on the relationship between the sail and the ship.

Horizontal sails, multi-purpose square sails, are basically a fixed sail. When pulled up with the wind, the effect is better than that of the vertical sail. When the wind is lowered, it is driven by manpower or other power. , multi-purpose jib sail, is a kind of sail that can be rotated back and forth, easy to operate, can be used in both downwind and upwind, and is less affected by the wind direction.

   A necessary condition for using a schooner is to have a rudder that can flexibly adjust the direction of the bow. In China, the rudder was invented very early, and it has always maintained a leading position in the world. The West did not have a rudder until the 12th century AD.

It is not to say that there were no vertical sails in the Han Dynasty. As early as the Warring States period, the prototype of the vertical sail appeared. In the Han Dynasty, the balanced vertical sail also appeared. The sail can be rotated to move the center of wind pressure to the rear of the mast, and It is very close to the mast, so the turning of the sail is less labor-intensive. But Ma Jun is not a professional shipbuilder after all, so it is normal that he did not understand the technique of balancing the schooner when imitating the building ship at the beginning.

   Now, this short board has been filled.

   With the jib, schooner, and rudder, basically the boat can take advantage of the wind from all directions. As for the follow-up, such as adding smaller auxiliary sails, such as the small sail of the gaff, the top sail on the main sail, etc., that is the follow-up evolution.

  Here, the reason why Fei Qian does not all use four-corner sails or trapezoidal sails is because of the size of the boat. Although everyone knows that ships with more sails can run faster, the wind blowing on the upper part of the sailboat will not only generate horizontal thrust, but also generate upward lift. When the lift force is relatively small, it is conducive to the fast sailing of the ship close to the water surface, but if there are too many sails, the ship is too small, and the upward lift force is too large, it is easy to cause the ship to capsize.

   Therefore, if the ship allows, the combination of the triangle sail and the square sail can be used to ensure safe sailing no matter the wind is strong or the wind is small, and the wind is against the wind.

   As for making bigger ships, we still need to wait.

   What Fei Qian needs now is an inland river vessel that is relatively safe in the inland river environment, adapts to various wind directions, is faster, and is more convenient for transshipment, rather than a large warship that goes out to sea.

  By the Xuanwu Pool in the distance, Ma Jun was very excited.

Fei Qian came to inspect the new vehicles and boats before, but at that time there were no vertical sails, that is, the crossbars of the sails were basically stationary, but now that the new sails are adopted, the sailing ability of the ships is almost the highest. Peerless.

   And Ma Jun himself will become famous in one fell swoop. Of course, Hussar General Fei Qian deserved the most credit, but wouldn't it be a good thing to be able to fill in his name in the credit book?

  『Everyone cheer up! Check it out again! Ma Jun yelled at the sailors and craftsmen on the ship, "If the sea trial is successful, in addition to the hussar rewards, I will pay for you to have a good meal!" There is wine and meat, and the buns are full! 』

  『Oh oh oh…』

"Do not worry! 』

  『Ma Dajiang is proud! 』

  The sailor craftsmen on the ship responded in a hurry.

If it is about the understanding of ships and the familiarity with wood, ten Fei Qian may not be as good as one Ma Jun, but if it is about choosing the direction of research, or choosing the best one among many choices, it may be even It's the big man who combined all the people at the moment can't compare to Fei Qian.

This is not to say that Fei Qian is smarter than everyone in the big man, but that Fei Qian has experienced the information explosion of later generations, and the information that Fei Qian has mastered is the result of countless painstaking efforts and life-and-death experiments of predecessors. What came down was tempered slowly by countless successes and failures...

   This is the power of knowledge.

  The first trial voyage begins.

  Test speed first.

  Because there is no very delicate timing tool, it can only be a mode of using reference objects. Next to the new ships there is a standard manned barge which will be the reference for the new ships.

   Neither vessel had sails.

  艨艟 naturally rely on oars, while new ships rely on turbines.

   Following an order, the red flag was waved, and the two ships moved almost simultaneously. The boat is small, and the speed of starting is very fast. With the sound of the oarsman's chant, the uniform wooden pulp makes the boat break through the water quickly, rushing forward, and the new boat is thrown away by two in a blink of an eye. distance of the hull.

  Pang Tong, who was standing next to Fei Qian, raised his eyebrows slightly, and then glanced at Fei Qian. Seeing that Fei Qian was stable as usual, he continued to look down with his sleeves on...

The new ship is bigger, and of course it will take more time to go from stationary to moving, but after the huge wheel starts to spin, and the tumbling water splashes out from under the shutter, the speed of the new ship will slowly increase. , and then getting faster and faster. Although there is still a long distance from the scorpion, the speed it showed surprised everyone present at the ceremony.

   Although the Xuanwu Pool is large, the distance is limited after all.

  The new ship still failed to catch up with the warship in the end, but the speed and strength displayed far exceeded everyone's expectations. When the warship arrived at the other end of the Xuanwu Pool and started to turn around halfway, the new ship also arrived at the other end and began to turn around. Overall, it was only about 70% of the speed of the warship, but this speed, for such a relatively large ship Speaking of which, it's pretty good.

   In the battle on the water, a large ship with a body shape close to that of a large ship has a speed close to 60 to 70% of a more flexible warship. Anyone who knows a little bit about water warfare knows how powerful it is!

   Especially its acceleration and turning flexibility, people almost think that what is in front of them is not a large ship modified from a large ship, but a medium-sized fighting ship...

  The next experiment of the second project is to make more people stare wide-eyed, open their mouths wide, and look at everything in front of them in disbelief.

   Headwind sailing test.

In people's minds, headwinds can only be done by oars and manpower. Therefore, when the new ship is like a flexible fat man in the headwind situation, it pulls up the triangular schooner, and then uses the rudder and wheels Paddle, when there were splashes of water on Xuanwu Lake, everyone present couldn't help but let out all kinds of irresistible sighs!

Compared with the balanced schooner and square sail, it is more convenient in the case of headwinds. After all, the square sail has a large area. Because of the characteristics of the sail itself, when changing the direction of the sail, it will hardly have a great impact on the stability of the ship. Coupled with the role of the rudder, the ship is like a flexible water bird. , advancing in a left and right circular arc on the water surface, the speed of sailing is not bad!

  Even in the second half of the trip, the new ship stopped the paddles and just relied on the sails to go against the wind, which completely shattered the previous concept of "the wind is not feasible"!

   A group of officials, big and small, who watched the ceremony, praised loudly...

  『God bless the man! This is a sharp weapon of water warfare, a war of nations! 』

  『With such a strong ship, where can the Dahan River not go! 』

  『Who in ancient times called He Guang, a Wei Hang! Today, who says that the river is broad, and it can be crossed in a boat! 』

  『The big river is surging, and now there are strong boats, which can be used as a passage! 』

  『Cross-sea buildings and boats can break the waves, and the wind and clouds can move and travel to Shenzhou! 』

  『...Well, uh, Hussar Wansheng! Victory! 』
