Damn it, I'm in the garbage book I wrote

Chapter 211 Plate Knight
For this new thing, of course, we need to try and make mistakes bit by bit. There is almost no experiment in the world that can produce results the first time.

This three-layer plate armor is the first test result. Its protective capability is quite good and it can defend against almost all current mainstream long-range weapons within 30 meters.

The exception is the bed crossbow. Being hit by a bullet from that thing within thirty meters is basically no different from being hit by a fully loaded, speeding semi-trailer.

But therein lies the problem. The filling is not good. When it is hit by a blunt object, the nail surface will be dented and the asbestos inside will be squeezed out.

The cushioning provided by this is not enough. Of course, the ceramic pieces inside are still very powerful. Even if a heavy hammer hits it, it will break the ceramics inside and disperse the impact force. However, the animal skin on the bottom is not so good and cannot withstand the impact and the fragments caused by the impact.

change!
Because a lot of ceramic plates were made in the previous batch, the second round of improvements began soon. The plan after this improvement was to replace the base plate with paper armor, and then fill the gap between the face armor and the middle ceramic layer with a mixture of asbestos and cement slurry.

This can ensure strength and minimize the damage of asbestos. However, this solution also has a problem, that is, it is too heavy... After the cement is poured into the armor, the weight is even heavier than that of an all-iron armor, and the cement inside will shrink after drying. It is fine when it is left there, but it becomes shaky when running.

However, the protective power is really amazing. After adding asbestos fiber to the cement, it becomes extremely strong. A heavy hammer can cause it to crack but cannot break it. Coupled with the protection of the ceramic plate at the back and the cushioning of the bottom plate, it can be said that the protective effect has reached the ceiling level.

It was just the weight and shrinkage issues that forced us to keep changing the plan.

This third version of the plan cancels the grouting and instead uses directly cast plates to fit the ceramic plate in the middle. In order to reduce the weight, the weight of the asbestos plate is also reduced, but hundreds of ceramic supports shaped like go pieces are placed on its surface before it dries. This can maximize the striking surface and distribute the force more evenly to the surrounding area.

This third version of the plan was undoubtedly successful. After the four layers of plates were joined together, the overall thickness was similar to that of conventional armor, but it was nearly one-third lighter and more resistant to impact. Moreover, because it could be disassembled, the logistical pressure was much less.

But where there are advantages, there are disadvantages. The disadvantage is that such armor is more troublesome to wear and is easier to fall off.

But Xiao Xia couldn't concentrate on this now. After all, the Spring Examination would be held in a month, and he still had to predict the questions for the students in the academy.

The third day before the beginning of summer is the day of the spring examination. After Xia Lin came out of the workshop, he devoted himself to the academy. Compared with developing new products, giving students test questions is obviously more difficult. Even Xia Lin has a headache until midnight every night, and he has to go out to swim in the sea of ​​questions with students early the next morning.

The tactic of doing a lot of questions is to go through all the possible questions. Even if you can't get the answer right, at least you can have a general idea of ​​how to solve the problem.

"Now A holds three liters of millet, B holds three liters of coarse rice, and C holds three liters of coarse rice. We want to add them together and divide them. How much do they get?" Xia Lin said in front of the book, holding the book, "This problem in the Nine Chapters on the Mathematical Art is very typical, and the solution is very clear. We can't just calculate it, we need to have a concept..."

When he was explaining the solution to the problem to the students, a head suddenly popped out from outside: "Master Xia, come here."

Xia Lin glanced at the person who came, put the book on the table and walked out: "What's the matter?"

"An imperial decree has come from above, asking you to go to Hongdu Prefecture on the sixth day of June." The person who came was a young eunuch. It seemed that his position was not very high, so he looked timid.

"What to do?"

"Hehe... good news. His Majesty has granted you a marriage with Princess Changle, and you will be the groom."

Xia Lin was stunned for a moment: "Who is Princess Changle?"

"Oh, it's Princess Changchun... Her Highness has been promoted, and now we all have to call her Princess Changle."

I…fuck…

Xia Lin was stunned for a long time: "So... the marriage is granted?"

"Well, the Zongzheng Temple and the Ministry of Rites have sent people to Hongdu Prefecture to make preparations. His Majesty knows that you are busy, so you can just go and participate when the time comes. Arrive two days in advance and go through the procedures."

"Then I have become the imperial concubine?"

"Don't worry, after your majesty discussed with the Ministry of Rites and the Ministry of Personnel, from now on there will no longer be the position of the imperial concubine's son-in-law. The imperial concubine is the imperial concubine."

My goodness, the old man really cared about this. Even Xia Lin felt that this was an unprecedented grace. Not to mention that he upgraded his wife to the eldest princess, he also changed the ancestral law specifically for him. This is really... Otherwise, the old man can rely on his personal charm to freeze the country that is about to fall apart. This is not just the empire's mender, this is simply the empire's universal glue.

Now that things have come to this, Xia Lin can forget about rebelling. Even if he has some connection with the rebels, he will be classified as a traitor in history books.

Come on, old man, this is all you can do. There's nothing much to say. Just accept the order and thank the teacher. After returning to the classroom, what they just said was actually heard by the students below. How could these 15-16, 17-year-old boys have the heart to attend the class? The noises of booing continued, causing Xia Lin to bang his head on the table.

"That's about it. Do you still want to take the exam?"

However, not long after the class resumed, one of the workers in the workshop suddenly rushed over, came to the door breathlessly and said: "Master Xia! The baseboard is ready!"

When Xia Lin heard this, he slammed the book on the table and said, "Study on your own."

After saying that, he followed the man all the way to the workshop. When he got there, he just happened to see the master craftsman in the workshop shooting at the composite board in front of him with a powerful crossbow, but even the crossbow could not penetrate that thin layer of board.

Xia Lin walked over and took it in his hand and felt that it was much lighter than before. But when he saw the thing at the back, he felt it was a bit strange.

"what is this?"

"Tung oil paper." The master carpenter beside him smiled and said, "Umbrella paper is stacked one by one, repeatedly beaten, tanned and dried. It is light, thin and strong. I tried using water, but it was too heavy. Oil is the best. It is light, thin and dense, strong and powerful. It cannot be cut by a knife, pierced by an arrow and weakened by a hammer."

"Good good."

Xia Lin took a close look at the layer of oil-paper armor. It was truly the result of the wisdom of the working people. It was definitely the final result after many tests. At this stage, there was almost nothing better than this.

After this series of improvements, the overall weight has been reduced from 62 kilograms to 39 kilograms while the helmet, arm armor and hand armor remain unchanged. The protective capability has hardly decreased and has even been significantly improved compared to the previous ability to resist blunt objects.

If the same solution is applied to horse armor, the weight of the entire suit will be reduced from two hundred kilograms to one hundred and thirty or forty kilograms. This will not only greatly improve the agility but also greatly increase the lifespan of the horse.

Of course, the more important thing is that such plates can be manufactured in large quantities and can even be used as shields or temporary fortifications, which makes them more widely applicable than simple iron armor.

The cost has also been greatly reduced, more than half the price of the original armor, and it may be even cheaper if produced in large quantities.

Original armor: cast from fine steel and hammered by hand.

Today's armor: mold assembly, mass production in workshops.

They say knowledge is power, isn't this a perfect reflection of that?

Originally, it took skilled craftsmen half a year to make armor, but now it only takes four or five workshops working together to produce a large batch in half a month. Even women can make the base plate at home. If they can make an umbrella, they can also make armor.

It is no exaggeration to say that this is a small step for Xia Lin but a big step for the heavy cavalry.

The next step was to really test the intensity. Xia Lin took out the few shotgun bullets for high-intensity testing.

The first round of tests was shooting within thirty meters. The "composite armor" could resist lead shotgun shells but not slugs, and iron filings were like tickles to it.

The second round of testing was shooting within ten meters. The lead bullet could penetrate two layers, but after breaking the third layer of ceramic, it lost its strength and was blocked by the fourth layer of cardboard.

The third round was hit on the chest... Well, this one penetrated through, but a serious person would not use lead bullets to hit heavy armor, and the single-headed bullet still had a strong killing power.

After this kind of high-intensity test, ordinary attack tests are no longer necessary, conventional weapons are ineffective, and overall, Fuliang's technology tree is much higher than that of the outside world.

After all, no one can swing an 2-jin hammer on a real battlefield. Usually, the weight of a bone fragment ranges from 5 to jin, so as long as it does not hit a vital part, it will not kill the enemy in one blow.

Of course we do not rule out those with amazing arm strength, but they are few in number after all.

But it's different here. The cavalry can be equipped with a flintlock or a shotgun, and fire a shot in the face. When targeting the same heavy cavalry, it is like a palm thunder. Even if the person does not fall down, the horse will probably be frightened.

The only things that can restrain heavy cavalry are heavy cavalry and machine guns. Without machine guns, there is only heavy cavalry left. And the heavy cavalry here is equipped with shotguns, so won’t the opponent be beaten like dogs?
However, Xia Lin was no fool. He did not rush into mass production, but asked the workshop to make fifty sets to try. After all, the equipment needed to be tested to know whether it was useful. If problems were found during the drill, they could be improved. But if problems occurred on the battlefield, what would happen if he fell off the horse would not only cost his life, but also silver that was heavier than his weight.
