Plague does not distinguish between men, women, old and young, nor east, west, nor west, but this thing likes chaos. The more chaotic and disorderly it is, the easier it is to spread.
Symptoms of the plague also appeared here in Cao's army. Some soldiers fell ill and died. However, what was different from the chaos in Jiangdong was that when Man Chong discovered the problem, he took out a "cheat sheet".
"Clear all feces and urine around the camp! Zhang Tuen, I leave this matter to you. I will give you fifty civilians. It must be cleaned up today!"
Zhang Tuen Chang received the order with a sad face. This job is the dirtiest and most tiring, but it is a military order and must be done.
"Leader Li, I will give you 50 civilians to go to the county to recruit and burn mirage charcoal. You must pay at least five carts within three days! If you are short of a cart, you are the only one to ask!"
Mirage is quicklime.
It is not an easy job to do this thing. Fortunately, Xiapi Guangling is close to the seaside, otherwise it would be really not easy to get shells for a while. Although he knew it was not easy, Captain Li had no choice but to accept the order.
Other jobs are actually not easy either.
"From today onwards, all civilians will form formations, select team leaders, and implement continuous sitting!"
"Bodies of those who died of illness must be burned and buried without delay!"
"Dead fish, shrimps, rats, and other dead things must not be eaten!"
"Dig a ditch in the shack area and introduce live water into it! All houses and shacks, starting from the leeward point, will be flooded!"
"Open a new hospital camp, build additional huts, lay charcoal, and set up fences!"
"The clothes and utensils of those who died of illness must be burned and buried!"
Man Chong explained one by one, but then his eyes dropped slightly and fell on the table. He checked it again and found that there were no mistakes. Then he said in a deep voice: "Everyone performs your duties and works together to prevent this plague."
, it will be destroyed soon! Go away!"
The large and small generals in the Chinese army's tent responded with a bang, and then went out to take action. There was a burst of people shouting and neighing in the camp, but it did not appear to be chaotic. On the contrary, under the leadership of the generals at all levels, they gradually began to
Entered into an orderly process.
Man Chong exhaled slowly.
He also did not expect to encounter the plague.
But Man Chong's advantage was the "cheat sheet" in front of him, a copy of the regulations that came from Guo Jia regarding the three assistants in Guanzhong's response to the Tongguan plague and the accommodation of refugees.
In fact, the symptoms of plague are not difficult to distinguish. Vomiting and diarrhea can quickly cause death and are contagious, so it can basically be determined to be a plague. Although Man Chong is not clear about it, no one will even understand these plagues for a long time.
Where did it come from and why did it become infected, but this does not prevent Manchong from taking countermeasures based on this "cheat sheet".
In the current Han Dynasty, the most important thing when facing 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. The only effective measure is to establish isolation zones, such as separating mountains and forests.
It's like a bare isolation belt is opened inside. Even if a certain area is burned out, as long as it doesn't burn to other places, in the end, as long as the fire in the burned area slowly extinguishes, the fire will be over.
This method is somewhat helpless, but it is also the best coping strategy at the moment.
As long as the peasants or refugees are given a certain amount of food, these peasants and refugees will not catch those mice or eat those dead objects, thereby reducing the chance of being infected by the plague and avoiding the scope of continued illness.
continues to expand.
A whole set of "cheat sheets" for recruiting refugees, providing disaster relief, and preventing disasters. In fact, every item is concise and concise. Guo Jia specially brought it out from the three assistants in Guanzhong, and then also got the backup in the political upper class around Cao Cao...
In fact, before Guo Jia's cheat sheet, Lao Cao had some reference to the various health regulations in the Hussars. There were really no "health regulations" these days, not only ordinary people, but also the children of the gentry.
Exception. Even in the Jin Dynasty, weren't there many noblemen who even thought it was elegant to catch lice with their bare chests exposed after knocking off the Five Stone Powder?
At first, many nobles, including Man Chong, did not take these things seriously, and did not think that these "cheat sheets" had any practical value. However, the issue of the refugees in Jingzhou was indeed reflected in the faces of the Cao family and Man Chong.
Baji slapped him loudly.
Especially Cao Zhen. He came back with his face covered.
It was from that time that Cao Jun began to implement these health regulations.
For the same reason, Man Chong and other talents pay special attention to these "cheat sheets" for preventing and controlling the plague, and even carry them with them...
"Husband..." Manchong slowly touched the cheat sheets spread out on the table, then grunted something from his throat, which eventually turned into a gentle sigh.
……(?д?)……
When the plague was spreading between Qingxu and Qingxu, Fei Qian took a group of his men to the Xuanwu Pond outside Chang'an City to review the latest ship construction status.
In ancient times, if you wanted to transport things well, wheels and legs were indispensable.
Four legs run on the ground, and boats float on the water.
For Fei Qian, if he wants to control a large area, cavalry is very important, but the navy is equally important, and among the navy, the most important thing is the ship.
Different ships, different sails, different technical requirements, and different channel adaptations.
Before Feiqian, the Han Dynasty's demand for ships was large, comprehensive, and beautiful.
In other words, the guiding ideology of ship manufacturing was still the same until the Ming Dynasty.
If a small one is easy to turn over, then make a big one.
If the wind power of a single mast is small, then use three masts. If that doesn't work, use five or nine masts...
It seems that there are many, but in fact the difference in technical content or variety is not very big. Some are simply the difference between one size smaller or one size larger.
The history of Chinese shipbuilding was already on a large scale as early as the Pre-Qin Dynasty.
Because after Qin Shihuang used force to end the hundreds of years of melee between the feudal Chu princes since the Spring and Autumn Period and the Warring States Period, in order to consolidate his rule and deter the remaining old aristocratic forces of the six countries, Qin Shihuang began to tour the territory of Qin. During Qin Shihuang’s fifth tour
, brought a huge patrol team to Yunmeng Daze, looked at Jiuyi Mountain in the distance, and after offering sacrifices to Yu Shun, they floated down the river, passed Danyang, went to Qiantang, crossed the Qiantang River, went up to Kuaiji Mountain, offered sacrifices to Xia Yu, and then
Returning to the land of Wu, he then took a sea-going ship and sailed north along the eastern coast of Qin to Langye. This was considered the earliest large-scale national coastal cruise.
Later, Qin Shihuang's patrol team landed at Zhifu, where they carved stones to record their achievements. This was Qin Shihuang's last patrol. It took several months for him to change from car to boat, from inland river to sailing.
It is conceivable that without the emperor's royal fleet with complete navigation equipment and good navigation performance at that time, Qin Shihuang would not have been able to conduct multiple long-term patrols in the rivers, lakes and seas, let alone cruise on the sea.
Of course, in fact, when Qin Shihuang visited the East, some of them were motivated by the desire to obtain the so-called "elixir" of the sea gods...
After all, most of the land at that time was conquered by Qin Shihuang, and the only thing that was not controlled by Qin Shihuang was the sea.
It's a pity that Qin Shihuang waited until his soul was gone and still didn't hear the news about the Immortal Mountain in the East China Sea.
In fact, at that time, if Qin Shihuang was like Fei Qian and claimed not personal immortality but immortality, but that there were mountains of gold and silver in the East China Sea, there were countless gold and silver everywhere, and rivers of precious stones, it would have been impossible to say that there would have been ships of the Qin Empire long ago.
We set foot on Yamatai.
The time when China clearly set foot in the "East China Sea" was earlier than what many ordinary people in later generations thought. Chen Shou of the Jin Dynasty used a considerable space in the "Three Kingdoms" to introduce some situations of the Eastern Japan. It shows that at least
During the Three Kingdoms period, he had already gone to sea and landed in Eastern Japan.
And Sun Quan might have used river boats to go out to sea...
Fei Qian is currently in Xuanwu Pond, and his main purpose is to point out some technology trees of ships first, and then build a transportation hub that connects the east, west, north, and south.
After all, there were nine galloping roads in the pre-Qin Dynasty. It makes no sense that they have degenerated in the Han Dynasty for three to four hundred years.
The previous flywheel was just the legs that Fei Qian put on the ship, but now the jib will become the ship's brand new wings.
In this era when there is no basis for steam engines, it is self-evident how important sails are to a ship. It can even be said that after the jib is hung on the mast of the ship, the technology tree of wind sailboats is basically the same.
An overall outline has been highlighted, and the rest is to add some details.
It's very windy today.
The wind is strong to facilitate testing. However, although it is generally considered a southerly wind, I don't know whether it is due to the Qinling Mountains or some other factors that cause the southerly wind direction. It is somewhat erratic and it is difficult to ensure the specific direction.
This caused great trouble for the navigation of ships.
However, this is also closer to the actual situation. After all, in rivers, lakes and seas, anything can happen.
The new type of ship is a large ship with three masts, a large quadrilateral sail and two large triangle sails.
The building ships built by Ma Jun before used horizontal sails.
The horizontal and vertical here does not look at the horizontal and vertical of the sail, but the relationship between the sail and the ship.
A square sail, mostly a square sail, is basically a fixed sail. When it is pulled up with the wind, the effect is better than that of the fore-and-aft sail. When it is lowered against the wind, it runs by manpower or other power, so the effect of the fore-and-aft sail is worse than that of the fore-and-aft sail against the wind.
, a multi-purpose jib is a sail that can rotate back and forth. It is easy to operate and can be used in both downwind and upwind. It is less affected by the wind direction. It is not as good as a square sail when going downwind, but it has strong sailing ability against the wind.
A necessary condition for using a longitudinal sail is a rudder that can flexibly adjust the direction of the ship's bow. In China, the rudder was invented very early and has always maintained its leading position in the world. In the West, it was not until AD
In the 12th century, ship rudders were introduced.
This is not to say that there were no fore-and-aft sails in the Han Dynasty. The prototype of fore-and-aft sails had already appeared as early as the Warring States Period. In the Han Dynasty, balanced fore-and-aft sails also appeared, which can rotate the sail and move the center of wind pressure to the back of the mast.
It is very close to the mast, so it takes less effort to rotate the sail. But after all, Ma Jun is not a shipbuilding professional, so it is normal that he did not understand the technique of balancing the longitudinal sail when he first copied the building ship.
Now, this shortcoming has been made up for.
With the jib, schooner, and rudder, basically the ship can take advantage of the wind in all directions. As for the subsequent addition of smaller auxiliary sails, such as the small sail of the sprit, the top of the main sail,
Sail and so on, that is the subsequent evolution.
Here, the reason why Fei Qian does not use all square sails or trapezoidal sails is because of the size of the ship. Although everyone knows that a ship will run faster with more sails, but the wind blowing on the upper part of the sailboat will not only produce horizontal waves.
In addition to thrust, upward lift will also be generated. When the lift is relatively small, it is helpful for the ship to sail quickly close to the water. However, if there are too many sails, the ship is too small, and the upward lift is too large, it will easily cause the ship to capsize.
Therefore, if the ship allows it, using a combination of jib and quadrilateral sails can ensure safe sailing regardless of whether the wind is strong or weak, tailwind or headwind.
As for building larger ships, that will have to wait.
What Fei Qian needs now is inland river vessels that are relatively safe in the inland river environment, adaptable to various wind directions, faster, and more convenient for transshipment, rather than large warships that go to sea.
At the edge of Xuanwu Pond in the distance, Ma Jun was very excited.
Fei Qian had come to review the newly built cars and ships before, but at that time there were no fore-and-aft sails, that is, the crossbars of the sails were basically immobile. But now that the new sails have been adopted, the ship's ability to sail is almost the best.
Unparalleled in this world.
And Ma Jun himself will also become famous in one fell swoop. Of course, the majority of the credit goes to General Fei Qian, but isn't it a good thing to be able to fill in his name in the credit book?
"Cheer up, everyone! Check again!" Ma Jun yelled at the sailors and craftsmen on the ship, "If the trial voyage is successful, in addition to the hussar reward, I will also pay for you to have a good meal and a drink! There will be wine.
Meat, steamed stuffed buns are enough!』
"Oh oh oh..."
"Do not worry!"
"Ma Dajiang is so heroic!"
The sailors and craftsmen on the ship responded all at once.
If it comes to understanding ships and being familiar with wood, ten Fei Qian may not be as good as one Ma Jun. But if it comes to choosing the direction of research, or choosing the best one among many options, maybe even
It's the big man. Now, all the people put together can't compare to Fei Qian.
This is not to say that Fei Qian is smarter than everyone in the Han Dynasty, but that Fei Qian has experienced the information explosion of later generations, and the information Fei Qian possesses is accumulated by his predecessors after countless painstaking efforts and countless life and death experiments.
What came down was slowly tempered by countless successes and failures...
This is the power of knowledge.
The first trial voyage has begun.
Test the speed first.
Because there is no very sophisticated timing tool, we can only use the reference object mode. Next to the new ship, there is a standard manned stern, which will become the reference standard for the new ship.
Neither vessel had suspended sails.
The stern boat relies on oars, but the new boat relies on the turbine.
With an order, the red flag waved, and the two ships started moving almost at the same time. The boat was small and started very quickly. With the sound of the rower's trumpet, the uniform wood pulp caused the boat to break apart quickly.
He rushed forward through the water, and in the blink of an eye the new boat was thrown two hulls away.
Pang Tong, who was standing next to Fei Qian, raised his eyebrows slightly, then glanced at Fei Qian. Seeing Fei Qian's calm appearance, he continued to look down with his sleeves tucked away...
The new ship is larger, and of course it takes more time to go from stationary to moving. But when the huge wheel starts to rotate, and the rolling water splashes appear from under the cover, the speed of the new ship slowly increases.
, and then getting faster and faster. Although there is still a long way to go with the cockroach, the speed it showed surprised everyone who was watching the ceremony.
Although Xuanwu Pond is large, the distance is limited after all.
In the end, the new ship failed to catch up with Xuanwu, but the speed and power it displayed far exceeded everyone's expectations. When Xuanwu arrived at the other end of Xuanwu Pond and started to turn around, the new ship also arrived at the other end.
At one end, it began to rotate and turn around. Overall, it was only about 70% of the speed of the stern, but this speed was already quite impressive for such a relatively large ship.
In a battle on the water, a large ship that is close to a large ship has a speed that is close to 60 to 70% of that of a more flexible stern. Anyone who knows a little bit about water fighting will know how powerful it is!
Especially its acceleration and turning flexibility make people almost think that what they see in front of them is not a large-scale modified ship, but a medium-sized fighting ship...
The subsequent test of the second project made more people widen their eyes and open their mouths, looking at everything in front of them in disbelief.
Headwind sailing test.
In everyone's mind, the only way to move against the wind is to rely on oars and manpower. Therefore, when the new ship is like a flexible fat man in the headwind, it pulls up the triangular sail, and then uses the rudder and wheel to
When the paddle stirred up splashes of water on Xuanwu Lake, everyone present couldn't help but let out all kinds of uncontrollable sighs!
Compared with the balanced fore-and-aft quadrilateral sail, the jib sail is more convenient in headwind conditions. After all, the quadrilateral sail has a large area. When it is turned, the wind volume will increase and decrease, causing the ship to become unstable, while the jib sail will cause instability to the ship.
Because of the characteristics of the sail itself, when changing the direction of the sail, it will hardly have a big impact on the stability of the ship. Coupled with the role of the rudder, the ship is like a flexible water bird.
, advancing in left and right arcs on the water, and the sailing speed is not bad!
Even in the second half of the trip, the new boat stopped its propellers and just relied on the sails to sail against the wind. This completely shattered the previous concept of "it is not feasible to fight against the wind"!
A group of officials, big and small, who were watching the ceremony, all praised loudly...
"God bless the man! This is a weapon for water warfare, a war of nations!"
"With such a strong ship, there is no place in the Han River that cannot be moved!"
"In ancient times, who said a river was wide and a reed hung across it! Now, who says a river is broad and a boat can cross it?"
"The river is surging, but now there are strong boats, which can make it clear!"
"A boat can cross the sea and break the waves, and it can travel to the Shenzhou in the wind and clouds!"
