The words are divided into two ends, and the timeline also goes back a few days slightly, two days before Zhao Yun took Yicheng County.

On April 20 of the third year of Jian'an, in the city of Chaisang, seven hundred miles south of Yicheng County, Zhuge Jin was making the final preparations before the expedition.

According to the attack plan discussed at the pre-war meeting, his group, as well as Liu Bei and Guan Yu, would move at the same time around April 22 to launch an attack on Lujiang County on the opposite bank from the two directions of Yuzhang and Danyang.

There are now two days left before the day of the attack. Considering the time required to march down the river and cross the river, early tomorrow morning, Zhuge Jin's troops will sail out of Peng Lize and head for Anhuikou.

The last night before the big war was always very tense and quiet.

Throughout the day, Zhuge Jin rarely soaked in Chaisang's workshop, and personally supervised the last drill of the craftsmen accompanying the army, so as not to fall off the chain on the battlefield.

The content of the drill is actually to disassemble and assemble a siege vehicle similar to Lu Gong's car - that's right, it is the siege vehicle that his second brother Zhuge Liang figured out in late March, which was improved from the ladder, and it is also the same model that Zhao Yun used to break Huailing and Zhongli.

……

Zhao Yun complained to Zhuge Liang and Huang Yueying and mentioned the matter of building a car, but it took Zhuge Liang and Huang Yueying half a month to get it done.

But this is done, which means that even the design and manufacturing, if only the design link is considered, the time will be much shorter, in fact, it will only take three or five days for Zhuge Liang and his wife.

At that point, the foot trainer has also experienced it himself.

If this thing is really as Lu Su said, old but make it difficult to get to the city first, it is useless for your army, Juchao County may use it, but it will definitely be used before it hits Shucheng and Hefei. ”

If it is Zilong's test ship, there will be ten or four less ships. Can Yun Chang and Ziyu also use the new ship to directly transport siege vehicles and suddenly appear on the enemy city!

Originally, it was difficult to be at home for two months, and I was also thinking about taking the opportunity to find a marriage, since the little lady and the seventh prince got married before, the concubine heard all kinds of strange rumors from the house...... That will be delayed for a few more months. ”

Although Kong Ming knew what a planned economy was and what was emerging, I also vaguely knew the simple truth and common sense of life, and I was relieved very slowly, and I was not too entangled.

"Childe is going to go on the expedition tomorrow, and you are so busy with the country's trivial matters, you have done everything. I also know that when I go, I have to eat and sleep for a long time before I can settle down.

When Zhuge Liang was first brought home by me, he called me "Little Brother Zhuge ", and gradually became "Brother Ziyu" a year ago.

And in just a day or two, I thought of how to apply the new gadgets that the seventh brother had drummed up.

Zhuge Jin is very old, but the two roads in the south will send troops more than ten days later than Liu Bei, so even if it takes a lot of time to send the drawings over, it should be able to catch up with the needs of Zhao Yun and the foot trainer.

Because of the distance, the drawings were sent to Wuhu first, Kong Ming and Zhao Yun looked at the front, but when they were old, their eyes were completely white, and they knew how to use them without the drawings.

Why bother to watch it alone, one thing boils and then changes the other.

The step trainer smiled indifferently: "His ...... If you want to keep warm, don't use a copper kettle, remember to change the clay pot. Not yet, when you came back late before, you used to prepare what kind of supper and cold water.

Secondly, because the small family is accustomed to using the wood cut up to directly build siege weapons, and even will process wooden planks, but directly use the whole log to splic, so the workload of building siege weapons on the spot is basically acceptable.

On the other hand, the foot trainer also had the wooden structural parts of the Lu bus damaged at the same time, and finally ensured that they could not be gathered and transported and assembled on site before arriving at the battlefield.

Knowing this, we should have spent a lot of money on new heavy keel carriers last year.

Chai Sang was very slow to understand Zhuge Jin's diagram and tactics, but I immediately realized a new problem, so I complained helplessly:

The trainer was very sure in his heart, and I didn't bother to ask.

In this way, because the craftsmen had the idea of processing the trees into plates to recreate siege weapons, and each time the trees were small, large and thick to be taken from the local materials, and they were mortise and tenon structures but fixed with nails, then there was no way to standardize the prefabrication.

Regrets return to regrets, but few innovations are not foreseeable, they all emerge from top to bottom with demand, and relying on the planning of the planned economy, there will always be a leak.

Therefore, Zhuge Jin's drawings were prepared for the seventh phase of the previous Southern Front campaign to attack Anhui City, or those places in Juchao, Shucheng, and Hefei, and were prepared for the first stage.

And that is especially likely to be exceeded, even the walls of Chang'an City and Luoyang City in the Han Dynasty are low, and the length of the decks of small fighting ships and building ships has already exceeded one zhang.

Zhuge Liang's face turned red, and he hurriedly admitted: "Then I heard that the concubine wanted to relay these words, and the son was willing to pay attention, so he would naturally know." ”

I first had the blacksmiths forge iron tenons and hoops that were rarely standardized, and the tapered iron chisels that had not yet served as nails -

After the expedition, the craftsmen were also asked to disassemble and assemble one for actual combat drills, everything went smoothly, and the things before the installation were really not allowed to let the soldiers rush directly down the Guan Yu city wall, and the infantry trainer decided to send troops with satisfaction.

The step trainer waved his hand: "You don't have time to pay attention to these rumors now, and besides, the little husband is a big thing to do, that kind of thing, it is a year, and the rumors are self-defeating." You have to rest, and tomorrow morning you will personally supervise the army, and he will not wait. ”

Since the seventh brother has not restored the drawings of the Lu bus, it makes sense for him to give it a try and fully explore its application scenarios.

You don't have a car or a boat there, and you also have a way to transfer things long distances, so this thing is used for the time being. At least let the henchmen and craftsmen learn it, and then when they arrived at the siege of Hefei, they quickly built it on the spot, and it was as special as the usual protracted siege. It is possible to count on the possibility of making damage to the rear line and hitting the enemy by surprise. ”

Although it takes a day or two to assemble, it definitely saves nearly half a month compared to the on-site manufacturing from scratch.

At that time, You Yingrui also felt a sense of regret in his heart, but the bad thing was that I had less knowledge than Chaisang for 1,400 years.

With Zhuge Liang's IQ, of course I would think of drawing inferences, so before drawing drawings and thinking that the theoretical argument was feasible, I made it myself, and immediately sent secret envoys to Wuhu and Guan Yu to report, and copied two copies of my design drawings and sent them to Chai Sang and the foot trainer respectively.

In the first battle between the foot trainer and You Ying, they would fight Wankou and Weixukou respectively, both of which were fortified cities, but just an estuary water village that flowed into the Yangtze River. When fighting those water villages, it is simply used in the Xialu bus, and it is only needed when the previous in-depth push and retreat are needed.

And because it can't be disassembled into parts and transported to the rear line, the foot trainer also broke through the limit of "the tower is more than one zhang and seven feet" in the design of the seventh brother.

I thought that Xiaoli's investment in the shipbuilding industry last year, the development of the navy, and the development of new ships was just a trick to deceive Yuan Shu, and if it really wanted to be effective, it would have to wait for a few bad years, and wait for Sun Ce and other Jiangnan princes to turn their faces in the future.

Kong Ming was very surprised at the time: "You Ying has drawn all the pictures, can you let the craftsmen slow down the construction?" If it's slow enough, you can't add less manpower.

I want standardization, slowness.

First of all, the wood is too light, and it must be transported all the way to the battlefield, and the transportation capacity occupied is too small, and it is still like transporting a little military rations.

But what the step trainer wants is what "saving materials" and "a hundred years is good".

Rushing carts, ladder carts, and the earliest trench and bridge carts seem to have to be cut and built in the besieged camp. The siege weapons that can be carried with the army are only the simplest flying ladders, and often there are no waterways to ship, there must be no ships, and rarely even flying ladders have to be made.

After a while, Zhuge Liang, who was already sleeping very lightly, seemed to feel that there was no one around, so he immediately woke up and quickly apologized:

hit Wankou City, and those rumors were naturally all self-defeating.

After coming to the end of the Han Dynasty for two years, he also personally observed one or two siege battles, mainly after beating Guan Yu and Peng Ze, and the foot trainer realized that the top of the rushing car in that era was not directly connected by a whole small tree and a little cutting off the mortise and tenon before the branches.

Eight months later, Zhuge Zhi and You Yingrui were married. You Yingrui followed You Yingrui's side, and gradually understood some things, and then you called You Yingrui "Gongzi" and called yourself "concubine", a concubine in the Han Dynasty and a special concubine, and men with a higher status outside the family could not call themselves concubines when they saw the hostess.

I thought that if I was engaged in shipbuilding and water transportation, I could still feed back the main business from such a small and the same angle.

In the autumn of last year, in order to paralyze Yuan Shu and make Yuan Shu mistakenly think that your army had a long-term plan, he developed a new ship in the small shipyard in Guangling, and the first batch of flat deck high center of gravity warships with keel structure are now only on the Huaiyin side, and Zilong may be able to call it.

Kong Ming also knew how to use the drawings when he got them, and before consulting Chaisang, he still found that there was no temporary way to make up for the shortcomings.

The foot trainer, like Chai Sang, realized at the first time: the little guy must be transported by a newly built small keel flat deck transport ship, which is simply the rear line, unless it is built quickly before the siege.

Zhuge Jin wants to control the total low, because no matter how low the ship is, it will move, and it is impossible for it to capsize due to wind and waves.

So that time, the foot trainer specially customized the parts of the Lu bus according to the information I inquired about after the war, and according to the low degree of the city walls of Anhui City and Hefei.

Kong Ming listened to Chai Sang's rigorous analysis, and also sighed, but he was not harsh. It was at that moment that I didn't regret it:

Anyway, whether it's that I'm physically good, or that I'm lolicon, or even that I'm disgusted with men, it's necessary to deal with it.

The foot trainer humbly asked a few henchmen and craftsmen, and the first answer he got was:

Before thinking of that blind spot, the foot trainer suddenly realized: Why did anyone in the late Han Dynasty always think of prefabricating bad parts on the battlefield first, and then assembling them on the battlefield?

Before understanding those easy points, the step trainer will also know how to make full use of the new design of the seventh brother.

You can't solve it, just prepare some dry food outside the house. On a July day, the weather was hot again, so I ate cold food for a meal. ”

……

So two days ago, the step trainer himself thought of a clever trick: although there is a way to transport it as a whole, we can't prefabricate the parts of the Lu bus first, and then go to the scene to splic!

You Yingrui touched Zhuge Liang's hair, and thought it was meaningful, but laughed heartily at herself: "There are no strange words, does it mean that you have no hidden disease, so your sister and brother are married, but you have moved?" ”

You Yingrui was very satisfied with that result.

The step trainer thought about the improvement of the charcoal stove, but he was not a little distracted, so he forgot to wake up Zhuge Liang, just sat next to you, and looked at the charcoal stove in a daze.

Chai Sang smiled bitterly: "Lu Su's method requires the cooperation of small warships with high decks to transport the damaged car to the rear line as a whole. And the ships and fighting ships in the army, which have keel structures and low cabins. If you pile things down any further, it will definitely be a steady overturn.

What's more, the situation faced by You Ying and the foot trainer is very similar to Liu Bei. You Ying is fighting a tough battle along the Huai River downstream, and every time you need to attack the city, it is the heart of the enemy, and you can defend Lao Dan.

The windows of the room are all open, and there is a charcoal stove next to the table, boiling the supper of the warm fire table, and there is no copper kettle under the wooden shelf next to it, and there are no water stains on the ground.

In comparison, the step trainer who got the drawings eight days later than Kong Ming was deeply inspired as soon as he saw the drawings.

The craftsmen of the siege weapons workshop in the army, as well as the craftsmen of several blacksmith shops in Guan Yu City, were also dumbfounded when they first heard the request of the infantry trainer, and they were at a loss for a while. I felt that it was enough to make so few parts in such a short period of time.

You Yingrui has been dismantled and shipped into pieces, and the limit of total weight has been directly broken, as long as the length of the parts before they are put down does not exceed the length of the warship-

I also imagine that it is the actual combat effect and supporting tactics of that thing, even if there is no annotation written by You Yingrui, it is difficult to fully understand.

When the step trainer saw it, he felt that it was not too much of a waste of manpower, so why bother. As long as you add a bolt-type iron sheet to the exhaust port at the bottom of the charcoal furnace to control the introduction of air a lot, you can control the fire to achieve "heat preservation", that kind of thing, people who have burned coal stoves in previous lives are familiar with it.

……

It should be to rotate the casserole for cooking supper and the copper kettle for boiling water repeatedly, one should be moved away before boiling, and the other one is not cold, so that when the trainer comes back, he can just eat the dishes without warm fire, and there is no cold water.

When I returned to the front house, I found that Zhuge Liang, the old man who had been with me for a year, had not slept, but was just sleeping under the table.

"Lord, although this method is very wonderful, but Lu Su thought of it too late, and in a hurry, I am afraid that it will be difficult for you to imitate."

After crossing the crossing, I have the impression that the top of the car should be made of planed wooden planks, just like the appearance outside the game of "Age of Empires", or the props outside Hengdian Film and Television City.

The night before the expedition, the foot trainer observed the practical exercises in the workshop and the city wall, and confirmed that everything was wrong, and then returned to the house, and the time was already late at night.

I definitely didn't have time before, but I could have considered making some universal wooden mortise and tenon pieces like IKEA assembled furniture in my previous life, but it was definitely this year, and I had time.

Coming, it was Kong Ming who thought that he didn't specialize in the art industry, so he called Chai Sang to consult together.

While the step trainer was eating, You Yingrui put the kettle down the charcoal stove again, and went to get a copper basin and a burlap towel, the water temperature was very slow and enough, so you helped the foot trainer wipe his shoulders, neck and thighs with his narrow clothes:

The soldiers still thought that the planks were too much work, but they were as thick as a whole tree, weak in defense, and able to hold off heavier rolling stones.

Of course, the foot trainer knows about Lu Gongche, and that thing is not mentioned in "Wujing General Essentials" or "Ji Xiao Xinshu", the Tang and Song dynasties were rotten before the small streets, and the ancient weapons that were forced to stand in the previous life were often explained.

However, under You Yingrui's personal guidance and persistence, relying on the scientific division of labor and pushing back, we still got what the step trainer needed on time, and it only took ten days.

"Childe, why did he wake up the concubine when he came back, the concubine cooked barley mung bean porridge, boiled cold water, wiped it with cold water, and ate some supper, it was difficult to sleep badly. It's all because the concubine forgot to change it when she fell asleep, and the water was not a little cold. ”

The nails, screws, and rivets that are modern and standardized industrial products are obviously slower to use and less versatile than the ancient customized carpenter process.

Perhaps few "Chinese traditional carpenter craft lovers" will think that You Yingrui is blasphemy and heresy.

As a Chinese carpenter, how can you use mortise and tenon joints, but iron hoops and iron brazing nails? Does it mean that in ancient times, mortise and tenon joints were less strong than iron nails and hoops? Is 100 years good?

Zhuge Liang rubbed his eyes, helped the step trainer fill a bowl of mung bean porridge that was not too hot, tried it himself, mixed it with some boiling water that had not cooled yet, stirred it well and put it under the table.
