Three Kingdoms

Although most of Fei Qian's territories are inland, Fei Qian has not relaxed his research on ship technology because of this.

The technological branch of ship technology is not a separate branch. In fact, there are many aspects that are interrelated with other technologies, such as metallurgy and architecture.

Let alone metallurgy, how can architecture be connected with ship technology?

Indeed there is.

A combined display structure of metallurgy, architecture, and ship technology is the dock.

Whether it is a new ship building or a ship repair and maintenance, a dock is required.

After a war on the water, ships will inevitably be damaged. If the basic structure is intact, it's just that too many holes have been opened on the deck of the ship, and some places are burned out, making it impossible to continue sailing. When the waves bump, water pours straight into it.

Are such ships discarded or repaired?

The answer is that I can cultivate it and I will try my best to cultivate it.

As long as the basic structure is intact and important components such as the keel are not damaged, it will be repaired.

If you only need to build ships, you often choose a natural port and directly build a simple wooden frame or other type of "natural dock". However, natural docks are often restricted by terrain. If you want to build a new one and repair it at the same time, you have to Faced with the need to temporarily build or add a dock.

What Cai He saw in front of him was such a semi-dry dock built with cement...

There is no water in a dry dock. The so-called semi-dry dock, of course, means that half of it has water and the other half has no water.

In fact, according to the needs of future generations for building and repairing ships, dry dock will naturally be better. It's just that the watertight materials of this era are not up to standard, and some water will still seep in. So there is still a little water in some places, so if it doesn't get in the way, don't worry about it.

Ma Jun also came up with the idea of ​​excavating a simple dock directly on the Yellow River, digging a long, wide and deep canal, and then building stone walls on the surface of the canal to glue it. After the canal is built, the water will be introduced, and the ship can follow the canal to the repair place. Then the water will be drained, and the ship can be repaired in this dock without water. After repair, the water will be put in , the ship can sail away.

Such a dock can naturally also be used to build new ships.

This plan was rejected because the investment was estimated to be too large. Mainly because without Lan Xiang's assistance, the amount of earth and stone was really a problem that could only be piled up by manpower, and the development of the Sanfu area in Guanzhong did not require manpower. of?

Later, under the joint discussion of Huang Chengyan, it was changed to another alternative plan currently adopted.

Easy slide.

The simple slide uses a wooden slide and a large amount of grease to replace the upper and lower piers between the water surface and the slipway. The advantage of this thing is that the equipment is simple and easy to operate, and there are not many requirements for the hardness of the rocks and soil on the shore. It is just that it cannot carry too heavy a ship. If Fei Qian really takes out the ironclad ship one day in the future, I'm afraid I just can't pull it anymore.

When facing a wooden building ship, this simple slideway similar to a semi-dry dock is quite good. Just level the original ground, add appropriate gravel and ballast, roll it flat, and pour cement. That’s it. And because of its simple structure, it is easy to disassemble and assemble. If you need to relocate, most of the equipment can be dismantled and moved to a new location.

Fei Qian took Cai He to see this dock to see the modification of old ships and the launch of new ships.

A layman looks at the excitement, an expert looks at the door.

Cai He is not a very good general. If he is allowed to go into battle to kill the enemy, he may not achieve much results, but his understanding of ships is better than many other generals.

Everyone has their own strengths, isn’t that surprising?

Except for the weirdo Fei Qian, he seems to know a little bit about everything.

It is precisely because of this that many people in Dahan admire Fei Qian very much. These people can't figure out why Fei Potential can do this. How many books do you need to read and how much knowledge do you need to master to do this?

In the end, in order to explain this point, it could only be attributed to Cai's collection of books. Then there were rumors that Cai's collection might contain Mohist treasure books from the Spring and Autumn Period, and there might even be unpublished books left over from ancient times. secret……

When Cai He saw the scene in front of him, his jaw had been drooping, and he couldn't close it properly.

Dahan's current natural resources are relatively abundant, so the wood needed for the shipyard here can still be guaranteed. With the addition of cement, a powerful weapon, although there is no such brutal model as E or F in later generations, At least it's close to C, which is pretty good.

At the same time, the development of metallurgy also allows Fei Qian to use part of the steel without hesitation, instead of having to select all the precious ironwood, saving part of the tree resources. The use of the boom pulley also makes manual towing relatively labor-saving. Concrete is poured into the steel pipe, and the bearings are lubricated with animal grease, so that the winch can withstand larger moments. Although it is not easy to deal with wooden ships, it is not easy. , but at least it’s not too strenuous.

It is mainly a wooden boat and has little weight. If you are not worried that iron will rust too easily, you can just use cast iron.

Cai He looked to the left, touched to the right, and almost surrendered to Fei Qian's entrenched attitude in the dock. Because he saw that some of the wood was high-grade wood that could be used as palace beams, and it had been dried in the shade!

What does this mean?

This shows that before this piece of 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 an extremely unusual arrangement on the building ship in the dock...

He was very curious, and he also realized that the special empty space might be a big killer, but he didn't dare to ask.

That empty space is reserved for artillery.

When attacking a city, artillery with insufficient gunpowder yield is actually not as intimidating and threatening as a kerosene catapult, unless the defenders on the city are willing to let Fei Qian put the artillery into the city gate and conduct direct fire to bombard the city gate.

Even if the city gate is directly bombarded, there are still ways to block the stone and sand to fight.

Therefore, what can make the artillery emit 100%, or even 200%, of its power is actually on the water.

In this era when ships are basically made of wood, the emergence of artillery is almost equivalent to a dimensionality reduction strike. It only takes one shot to directly send the opposite ship back to the port to take advantage of the barrel. It is not an impossible task.

There are gun ports on both sides of the large building ship.

Cai He watched and swallowed.

The side panel of the running position adopts a loose-leaf model, which can be pushed open and usually put down.

The position of the gun is fixed in the cabin to lower the ship's center of gravity.

In Fei Qian's eyes, those artillery pieces seemed a bit crude, bulky, even dangerous and inaccurate, but in this era, they were indeed products that transcended time and space.

Improved version of front-loading smoothbore.

Fei Qian smiled and took Cai He around without going into details. Anyway, he just let Cai He take a look and show off his strength.

It is not that easy for time-travelers to turn their knowledge into productivity.

A simple dock seems to be extremely crude compared to later generations.

But it’s actually not easy anymore.

Just like the various items on the building ships, at this stage, of course, paint is used as the main anti-corrosion method. This is also common sense that time travelers basically know, but should we use raw paint or cooked paint?

Some people say that it is better to use raw lacquer, while others say that it is best to use cooked lacquer, but Fei Qian knows that neither of these is good.

It should be anti-rust paint.

It's a pity that it is not available now...

All Feiqian ships can sail in fresh water areas, but once they sail into sea water areas, the life of the ships will be greatly reduced. Many ships that can be used in fresh water areas for more than ten years will not last more than ten years in sea water. It will corrode in five years. The reason is that Fei Qian could not come up with the kind of special anti-rust and anti-corrosion paint used on the bottom of ships in later generations.

Similarly, there are artillery. Fei Qian also knows that rifling is very important, but the problem is that materials science has not progressed enough. Even if materials science has progressed, processing technology must also be improved...

Fortunately, the steelmaking method of the Han Dynasty was already very good. The blast furnace and other things had already taken shape. Feiqian just added the research and development of refractory bricks and the converter plan, which made Feiqian's current steel output and quality both outstanding. Already standing at the pinnacle of this era.

Similarly, the technological development of refractory bricks has also further improved the technology of coal coking.

In the early days of Pingyang, Fei Qian used charcoal to make iron and steel.

Later, coal from the Luliang Mountains was used, but the impurities in the coal were troubled for a long time. Finally, a method similar to making charcoal was used to make coke, and for a time, local methods were used to make coke.

Although the local coking method can provide a large amount of coke at one time, the qualification rate is too low, and the related coking by-products, such as various oils, cannot be collected...

The development of refractory bricks makes it possible to use new furnace-type coking. Except for a few parts that require iron sheets, the basic materials are bricks and refractory bricks. The entire coking process takes about ten days, and the qualification rate of coking coal has also improved a lot. Of course, it is still far from the kind of later generations, but it is already very difficult. Going forward may require in-depth participation from the chemical engineering discipline.

The new coke oven can also use the gas generated by coking to circulate and heat the furnace body, and at the same time, it can recover part of the coal tar. The tar, which is cooled and recycled with water, will be collected into clay pots and sealed, and become kerosene, or other fuels, lubricants that replace animal fats, or some basic chemical raw materials.

The service life of iron cannons is relatively low due to their natural tendency to rust, and maintenance is more troublesome, but for Fei Qian, it has become a better choice.

After all, copper coins are still money today...

Cai He was so frightened that he was almost blinded by Fei Qian's aura. He immediately lowered his original expectations again and again, almost holding Fei Qian's thigh and crying and praying...

If Cai He is left in Chang'an for the time being, and he turns around and starts flipping the map to see the future opponents of Fei Qian and other buildings and ships in Jiangdong, he will find that Emperor Sun is actually very sad at the moment.

Emperor Sun's sadness was that he discovered that the situation in Jiangdong had become significantly better without him in power...

This is quite embarrassing.

Sun Quan actually wanted to carry out a series of reforms in Jiangdong.

If the powerful nobles of the Han Dynasty have influenced the court in many places, then in Jiangdong these powerful nobles and local gentry have not only influenced, but even determined various strategies of Jiangdong.

Sun Quan attempted to get rid of these Jiangdong clans, and then divide the counties and counties into separate systems, open up channels of speech, exercise the rule of law, and handle local affairs in accordance with the laws of the country instead of being controlled by the clans in the countryside. There is actually nothing wrong with this series of actions. If Sun Quan really does it, Jiangdong will become rich and powerful.

But Sun Quan was too impatient and immediately took over the land and military power.

Sun Quan rectified the land affairs, sent poor people 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 of Jiangdong, but they would seriously infringe on the interests of local nobles.

As a result, inevitable conflicts broke out.

Jiangdong suddenly became chaotic, rebels were everywhere, and South Vietnamese were causing trouble everywhere. These Jiangdong nobles owned land, population, wealth, and private soldiers. When these things were brought together, they formed a very powerful force that was enough to overturn the Sun family's foundation.

There was originally a rift in the Sun family...

In fact, no matter what Sun Quan did, it was useless to defeat Liu Biao or Cao Cao, because the people in Jiangdong would not give in because of certain achievements. Just like the Chu State in history, they once had a huge land. , once ruled the king and hegemony, but under the obstruction of the big nobles in the country, the reformers of Chu State did not end well. They were murdered and exiled. Basically, they all ended in tragedy.

If Mrs. Wu had not died, Sun Quan felt that he still had support, and there would have been a huge dispute in Jiangdong...

Sun Quan knew that although Zhou Yu usually talked about it and even despised his own stupidity and short-sightedness, he would still sacrifice himself as long as he really encountered any danger.

As for Zhang Zhao, Zhang Hong and others, they are just outsiders, so as long as Sun Quan has the support of his mother, then the Wu family relatives represented by his mother will naturally be basically on his side. In this way, as long as When the Sun family's foundation is really in danger, Mrs. Wu and Zhou Yu will join forces and go on a killing spree...

Therefore, Sun Quan is not afraid.

Children with mothers are bold.

Because he knows there are still people who love him.

After his mother died, Sun Quan became afraid.

When there are parents, brothers are brothers, and they still have a unified place of origin. When there are no parents, brothers may not be brothers, because they only have different destinations. This may be true between brothers, let alone other relatives of the Wu family who don't have much family ties?

The ruthlessness and tolerance in the Sun family made Sun Quan make an important decision. It was also the decision that made him look the most timid, but also the smartest. He handed over the political power and divided it into two. The military power was given to Zhou Yu. Government affairs were given to Zhang Zhao.

Then Jiangdong stabilized instantly...

With Zhou Yu and a group of uncle-level veterans sitting in charge, swinging big sticks around, no one in Jiangdong dared to move rashly.

Zhang Zhao on the other side was responsible for dividing the carrots, and discussed the contents originally formulated by Sun Quan that made the Jiangdong nobles feel uncomfortable. Most of them were overturned, and a few were left. Of course, more were still in place. A face-saving project...

For example, private soldiers.

Now it is clearly stated that "private soldiers" are not allowed.

But there is no rule against having "housekeepers".

My "servants" like to wear armor and carry swords and guns. I'm happy with that. Is there any problem?

It is stipulated that no more than 500 armed people are allowed in a manor, so that means 499 people in each manor...

Zhang Zhao laughed and everyone laughed.

Sit in rows and eat fruits.

In such a peaceful and peaceful atmosphere, Jiangdong's economic development is surprising. The rebellious people who had been summoned before returned to the fields again. Agriculture has recovered, handicrafts have also recovered, and the economy has improved. Jiangdong's fiscal deficit has also been greatly alleviated. As long as nothing unexpected happens, Jiangdong will be able to It’s sure to be a good year.

Sometimes things are so weird. Sun Quan desperately wanted to control Jiangdong, but Jiangdong was in chaos. But now that Sun Quan has let it go, Jiangdong has developed agriculture and mulberry trees, and the economy has prospered.

I don’t know if it’s because the Kodong nobles want to explain something through this current situation. Anyway, the current momentum of Kodong is simply extremely good...

Under such a good situation, Yujiang visited Sun Quan.

Sun Quan was on the mountainside, keeping filial piety for Mrs. Wu.

There are soldiers of the Sun family at the foot of the mountain and on the surrounding mountaintops, but they will not come up to this mountain unless there are special circumstances, because the entire mountain is the tomb of Mrs. Wu, and in Mrs. Wu’s grave Next to the tombstone is Sun Quan's temporary residence, a simple courtyard.

A simple wooden house, a small courtyard with not too flat soil, surrounded by a simple and rough fence as a fence.

There are some vegetables grown in the courtyard.

Sun Quan was like an old farmer, wearing linen clothes stained with mud.

Zhou Yu first paid homage in front of Mrs. Wu's tombstone, and then went to Sun Quan's courtyard and sat on the wooden floor in the front hall of the wooden house. "My lord, this place is quite clean..."

Sun Quan nodded slightly. There was no hatred, no anxiety, no resentment in his eyes, but they were not numb, just like a calm mountain pool, deep and deep.

Sun Quan now moves less, laughs less, and cries less. Except for going to Mrs. Wu's tomb regularly in the morning and evening every day, he seems to be in a daze the rest of the time.

Watching the sky clear, watching the sky cloudy, watching the clouds rolling and relaxing, watching the rain stop and the clouds disappear.

Watching the rain fall from the branches, watching the leaves wither with the cold wind.

Ever since he ascended to the position of Lord of Jiangdong, he has never stopped, and now that he is far away from the hustle and bustle, he can really look at everything around him.

Zhou Yu looked at Sun Quan, and finally saw that Sun Quan no longer had any hairiness, but began to look like a sword in a scabbard, with no brilliance exposed, but hidden sharpness.

Zhou Yu sat next to Sun Quan and slowly described the current situation in Jiangdong.

Zhou Yu is not showing off, but just describing.

Sun Quan listened silently, with neither anger nor sadness on his face.

After Zhou Yu finished speaking, he stood up and said he would come back next month. He did not ask Sun Quan for his opinion, nor did he express his desire to hear Sun Quan's thoughts.

Sun Quan also got up and sent Zhou Yu off.

Outside the fence of the small courtyard, Zhou Yu paused briefly and said goodbye to Sun Quan.

Sun Quan nodded, and then said when Zhou Yu turned around to leave: "I see that the governor's hair is slightly gray on his temples. Please take care of yourself and don't overwork yourself..."

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 model of "governing by doing nothing" happened to be in line with the prototype of "governing by decentralization", 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 turbulent undercurrent hidden.
