Although most of Feiqin's territory is inland, Feiqin did not relax the research on ship technology.
The technological branch of ship technology is not a single bare branch. In fact, many aspects are related to other technologies, such as metallurgy and architecture.
冶金就不提了,建筑学怎么可能和舰船技术联系到一起?
There is indeed.
Metallurgy and architecture, plus a comprehensive display structure of ship technology, is the dock.
Whether it is a newly built ship or a repair and preparation of ships, a dock is required.
After a war on the water surface, the ship will inevitably be damaged. If the basic structure is intact, it is just that there are too many holes on the deck of the ship, and some places are burned out and cannot continue sailing. When the waves bump, the water will pour straight into it.
Such a ship is just discarded or repaired?
The answer is that you can practice it and you will try your best to practice it.
As long as the basic structure is complete and important components such as keels are not broken, they will be repaired.
If you only need to build a ship, you often choose a natural port to directly build a simple wooden frame and other "natural docks". However, natural docks often have limited terrain. If you want to build a new ship and repair it, you have to face the need for temporary construction or additional docks.
What Cai He saw was such a semi-dry dock built of cement...
There is no water in the dry dock. The so-called half dry one is of course half has water and the other half has no water.
In fact, according to the needs of later generations to build and repair ships, it would be better to dry the dock. However, the water-tight materials of this era were not up to standard, and some water would still penetrate into it. There was still a little water in some places, so it would not be too much of a problem.
Ma Jun also proposed an idea, directly digging a simple dock at the Yellow River, digging out a long, wide and deep canal, and then building stone walls on the surface of the canal and plastered with glue. After the canal is built, the water can be introduced, and the boat can go along the canal to the repair place, and then drain the water. The boat can repair it in this dock without water. After the repair is completed, the water can be put in, and the boat can sail away.
Such a dock can naturally be used to build new ships.
This plan was rejected because the estimated investment was too large, mainly because without Lan Xiang's assistance, the amount of earth and stone was a problem of only manpower being used. Where does the development of the Sanfu area in Guanzhong do not require manpower?
Later, after Huang Chengyan's discussion, it changed to another alternative solution that is currently adopted.
Simple slide.
A simple slide is to use wooden slides and a large amount of grease to replace the upper pier and drainage between the water surface and the ship's platform. The advantage of this thing is that the equipment is simple, easy to operate, and there are no requirements for the hardness of the rocks on the shore, but it cannot carry too heavy ships. If Fei Qian really takes out the iron-clad ship that day in the future, he may not be able to pull it.
When facing wooden stairs, this simple slide similar to a semi-dry dock is quite good. Just level the original ground, add gravel, slurry, roll flat, and pour cement. Moreover, because the structure is simple, it is very convenient to disassemble and assemble. If you need to relocate, you can also remove most of the equipment and change it to a new place.
Fei Qian took Cai He to come to see the dock and see the modification of the old ship and the launch of the new ship.
A layman watches the excitement, while an expert sees the tricks.
Cai He is not a very excellent general. If he is allowed to fight the enemy, he may not have much success, but his understanding of ships is better than that of many other generals.
Is each of them good? It's not surprising.
Except for the freak Fei Qian, he seemed to know a little about everything.
It is precisely because of this that many people in the Han Dynasty admire Fei Qian very much. These people can’t understand why Fei Qian can do this. How many books do you need to read and how much knowledge do you master?
Finally, in order to explain this, it can only be attributed to the Cai family's collection, and then there are rumors that the Cai family's collection may include the Mohist books from the Spring and Autumn Period, and may even have the secret left over from ancient times...
When Cai He saw the scene in front of him, his chin was always drooping and he couldn't fit well.
The current natural resources of the Han Dynasty are relatively large, so the wood required for the dock here can be guaranteed. With the addition of cement, this weapon does not have the brutal model of E or F in later generations, but at least it is close to C, which is quite good.
At the same time, the development of metallurgy has also enabled Feiqian to use some of the steel without hesitation without having to choose all the precious iron and wood, saving some of the tree resources. The use of boom pulleys has also made it relatively labor-saving when dragging by manpower. By filling concrete in the steel pipes and lubrication with bearings and animal grease, the winch can withstand a large torque. Although it is not easy to deal with wooden ships, it is at least not too difficult.
It is mainly a wooden boat, which has little weight. If you are not worried that the iron is too easy to rust, you can only use cast iron.
Cai He looked left and right, and he almost wanted to be impressed by the richness shown in Fei's potential dock. Because he saw that some of the woods were high-quality woods that could be used as palace beams, and they were treated with dark dryness!
What does this mean?
This shows that before this wood was cut down, no, to be precise, before such a tree was cut down, perhaps Fei Qian was planning everything in front of him!
This made Cai He even more humble.
And Cai He saw extremely unusual arrangements on the building ship in the dock...
He was very curious and realized that the special vacancy was probably a big killing weapon, but he didn't dare to ask.
That space is left for the artillery.
Attacking a city, the cannon with insufficient gunpowder equivalent is actually less effective than the intimidation and threatening of turbulent oil casting cars, unless the defenders on the city are willing to let Fei Qian pass the cannon into the city gate and directly shoot and bombard the city gate.
Even if it directly bombards the city gate, there are ways to congested stone strips and sand to fight.
So what can make the cannon emit 100% or even 200% of its power is actually on the water.
In this era when they were basically wooden ships, the emergence of artillery was almost equivalent to a dimensionality reduction strike. Just one shot could directly get the opposite ship back to the port to eat a barrel, which was not an impossible task.
On both sides of the large building ship, there are muzzles left.
Cai He looked and swallowed.
The side panels for running positions are loose-leaf mode, which can be pushed away and put down normally.
The position of the artillery is fixed in the cabin to reduce the center of gravity of the ship.
In Fei Qian's eyes, those artillery that seemed a bit crude, bulky, even dangerous and inaccurate were indeed products that transcend time and space in this era.
Improved version of front-mounted smoothbore.
Fei Qian smiled and took Cai He around, without saying anything in detail. Anyway, let Cai He see and show his strength.
It is not that easy for time travelers to transform their knowledge into productivity.
A simple dock seems to be extremely simple compared to later generations.
But it is actually not easy.
Just like the various items on the building boat, at this stage, of course, paint is the main anti-corrosion and corrosion prevention method. This is also common knowledge that time travelers basically know, but should we use raw paint or cooked paint?
Some people say that it is better to use raw paint, while others say that it is better to use cooked paint, but Fei Qian knows that neither of these are good.
It should be anti-rust paint.
Unfortunately, there is no...
All ships in Feiqian can sail in the freshwater area. Once they enter the seawater area, the lifespan of the ship will be greatly reduced. Many ships that can be used in the freshwater area for more than ten years will be corroded after no more than five years in the seawater. The reason is that Feiqian cannot produce the paint that specializes in the anti-rust and corrosion-proof paint used in the bottom of the ship in later generations.
Similarly, there is artillery, Fei Qian also knows that rifling is very important, but the problem is that materials science has not made enough progress. Even if materials science has progressed, processing technology must be improved...
Fortunately, the steelmaking method in the Han Dynasty was already very good, and blast furnaces and other things have already taken shape. Feiqian only added the research and development of refractory bricks and the converter plan, which made Feiqian's current steel production and quality stand at the peak of this era.
Similarly, the technological development of refractory bricks has further improved the technology of coal coking.
In Pingyang, Fei Qian used charcoal to smeltet iron forging steel.
Later, the coal in Luliang Mountain was used, but he was also troubled by the impurities in the coal for a long time. Finally, he used a method similar to making charcoal to make coke, and once used the soil method to make coke.
Although the local coking can provide a large amount of coke at one time, the pass rate is too low and it is impossible to collect related coking by-products, such as various oils...
The development of refractory bricks has enabled new furnace-type coking. In addition to a few parts that require iron sheets, the basic materials are bricks and refractory bricks. The entire coking process is about ten days, and the passing rate of coking coal has also increased a lot. Of course, there is still a big gap with the later generations, but it is already very difficult. Going up further may require in-depth participation of the chemical engineering discipline.
The new coking oven can also use the gas generated by coking to heat the furnace body, and at the same time, it can recover some of the coal tar. The tar after cooling with water will be collected and sealed in the clay pot and become tincture oil, or other fuel, lubricants that replace animal oils, or become some basic chemical raw materials.
The lifespan of the iron cannon is relatively low due to natural rust, and it is also troublesome to maintain, but for Feiqian, it has become a better choice.
After all, copper coins are still money at the moment...
Cai He was trembling and almost blinded by Fei Qian's tyranny. He immediately reduced his original expectations again and again, almost holding Fei Qian's thighs and crying and begging...
If Cai He is temporarily left in Chang'an and ignore it, turn around and start to move the map to check the future rivals of Feiqian and other tower ships, when in Jiangdong, you will find that Emperor Sun is actually very sad at the moment.
Emperor Sun's sorrow was that when he found out that Jiangdong had not been in power, the situation in Jiangdong had obviously become better...
This is quite embarrassing.
Sun Quan actually wanted to carry out a series of reforms to Jiangdong.
If the Han gentry and gentry had influenced the court in many places, then the local gentry and gentry in Jiangdong had not only influenced, but also determined the various strategies of Jiangdong.
Sun Quan attempted to get rid of these Jiangdong clans, then divide the counties and counties, open up the rules of law, and handle local affairs in accordance with the laws of the country, rather than being controlled by the clans in the country. This series of actions was actually nothing wrong. If Sun Quan was really done, Jiangdong would become rich and powerful.
But Sun Quan was too anxious and immediately moved to the land and military power.
Sun Quan rectified Tian Zheng, sent poor families and clerks to various places to check the amount of land, and began to limit the number of private soldiers. Such measures were obviously beneficial to the overall situation in Jiangdong, but they would seriously infringe on the interests of local gentry.
As a result, inevitable contradictions broke out.
The Jiangdong gentry suddenly became chaotic, with rebels everywhere, and Nanyue in chaos everywhere. These Jiangdong gentry had land, population, wealth, private soldiers, and when these things were gathered together, they formed a very huge force, enough to subvert the Sun family's foundation.
In addition, there were originally cracks in the Sun family...
In fact, no matter what Sun Quan did, it would be useless to defeat Liu Biao or Cao Cao, because Jiangdong and others would not surrender because of some achievements. Just like the Chu State in history, they once owned huge land and once dominated the king. However, under the obstruction of the great nobles in the country, the reformers of Chu State had no good ending. Those who were murdered and those who were exiled were basically a tragic end.
If Mrs. Wu was not dead, Sun Quan felt that he still had support, and he might have a huge dispute in Jiangdong...
Sun Quan knew that although Zhou Yu was always muttering and even despising his stupidity and short-sightedness, he would still devote himself to Yu Jiang as long as he really encountered some danger.
As for Zhang Zhao and Zhang Hong, they are fence-bearers, so as long as Sun Quan gets the support of his mother, the Wu relatives represented by his mother will naturally basically stand on his side. In this way, whenever there is a real danger of the Sun family's foundation, it is when Mrs. Wu and Zhou Yu will unite to start a massacre...
Therefore, Sun Quan is not afraid.
Children with mothers are bold.
Because he knew that someone loved him.
After his mother died, Sun Quan was scared.
When there are parents, brothers are brothers, and there is still a unified source. When there are no parents, brothers may not be brothers, because only their own different places are left. This may be true between brothers, let alone other Wu relatives who do not have much affection?
The ruthlessness and tolerance in the Sun family made Sun Quan make an important decision, which also made him look the most cowardly but also the smartest decision. He handed over the regime, divided it into two, gave military power to Zhou Yu and government affairs to Zhang Zhao.
Then Jiangdong stabilized instantly...
Zhou Yu and a group of veterans from his uncles were in charge, swaying around with big sticks, and no one in Jiangdong dared to move.
On the other hand, Zhang Zhao was responsible for dividing carrots and took out the content originally formulated by Sun Quan that made the Jiangdong gentry feel uncomfortable one by one. Most of them were overturned, leaving a small part behind, and of course, more of them were projects on the face...
For example, private soldiers.
Now it is explicitly stipulated that "private soldiers" are not allowed.
However, there is no regulation that there are no "housekeepers".
My "housekeeper" likes to wear armor and swords and guns for them. I am happy, are there any problems?
It is stipulated that more than 500 armed people are not allowed in a manor, so that each manor is 499 people...
Zhang Zhao smiled, and everyone was also smiling.
Sitting in a row and eating fruits.
In such a peaceful and peaceful atmosphere, Jiangdong's economic development was surprising. Those who were summoned to cause trouble again returned to the fields, agriculture was restored, handicrafts were restored, and the economy was circulated. Jiangdong's fiscal deficit was greatly alleviated. As long as nothing unexpected happens, Jiangdong will definitely be a bumper year this year.
Sometimes things are so weird. Sun Quan tried his best to deal with Jiangdong, but Jiangdong was in chaos. Now Sun Quan stopped doing it. Instead, Jiangdong had developed agriculture and sericulture and its economy became prosperous.
I don’t know if the Jiangdong gentry wanted to explain something through this situation. Anyway, the momentum in Jiangdong is simply very good...
Under such a good situation, Yu Jiang visited Sun Quan.
Sun Quan was on the mountainside and mourned for Mrs. Wu.
There are soldiers from the Sun family at the foot of the mountain and above the surrounding mountain tops, but unless they are in special circumstances, they will not come up to this mountain, because the entire mountain is the tomb of Mrs. Wu, and next to Mrs. Wu's tombstone is Sun Quan's temporary residence and a simple courtyard.
A simple wooden house, a small courtyard with not too flat soil, and a simple and rough fence is surrounded by a wall.
There are some vegetables grown in the courtyard.
Sun Quan was like an old farmer, wearing hemp clothes and stained with soil.
Zhou Yu first worshiped in front of Mrs. Wu's tombstone, and then arrived in Sun Quan's courtyard and sat on the wooden floor in the front hall in front of the wooden house. "The lord is quite quiet here..."
Sun Quan nodded slightly. There was no hatred, no anxiety, no resentment in his eyes, but it was not numb, like a peaceful mountain pond, deep.
Sun Quan now moves less, laughs less, and cries less. Except for going to Mrs. Wu’s grave regularly in the morning and evening, he seems to be in a daze for the rest of the time.
Looking at the clear sky, looking at the clouds, watching the clouds roll and unfold, and watching the rain stop and disappear.
Watch the rain slide down the branches and watch the leaves wither withering with the cold wind.
Since he ascended to the position of the Lord of Jiangdong, he has never stopped. Now that he has been away from the hustle and bustle, he has truly watched everything around him.
Zhou Yu looked at Sun Quan and finally couldn't see any frigidity on Sun Quan. Instead, he began to look like a sword contained in the scabbard, with no light exposed, but hidden sharpness.
Zhou Yu sat on the side of Sun Quan and slowly talked about the current situation in Jiangdong.
Zhou Yu is not showing off, but just narration.
Sun Quan listened silently, with neither anger nor sadness on his face.
After Zhou Yu finished speaking, he stood up and said that he would come back next month. He did not ask Sun Quan if he had any opinions, nor did he express that he wanted to listen to Sun Quan's thoughts.
Sun Quan also stood up and sent Zhou Yu.
Outside the fence of the small courtyard, Zhou Yu paused for a moment and bid farewell to Sun Quan.
Sun Quan nodded, and then said as Zhou Yu turned around and left: "Seeing that the governor's temples were slightly white, please take care of his body, don't be too tired..."
Zhou Yu nodded, smiled and left.
Sun Quan stood on the mountainside and watched Zhou Yu go away. He didn't know that Jiangdong's "rule by inaction" model coincided with the prototype of "decentralization and governance", so it showed temporary prosperity.
However, the current political model of Jiangdong is not mature.
Sun Quan just understood that under the temporary prosperity on the surface, there was still a surging undercurrent.
