Three Kingdoms, at the beginning of the game, recognize the thief as the father, hit the spectacle,

Leaving aside the fact that cement is afraid of fire, once it is exposed to high temperatures, it will cause calcium silicate crystals to dehydrate. Even if there is no such thing, it is not a sensible act to use cement to cast artillery.

Perhaps this material is much easier to shape than metal, but due to the lack of ductility of the crystal, as long as the cannon made of this cement is fired, the cannon body will be immediately affected by the violent fluctuations caused by the explosion. crumble.

But then again, when God closes a door for you, he often opens a window.

Although the material of cement cannot bring any inspiration to the members of the Science and Technology Department in the manufacture of artillery, it is like the shell of the thunderbolt, and there are some similar things...

As long as you have a flexible mind, you can still imagine the use of things like cement.

For example, since it cannot be used to make the artillery itself, can it be used to make the base of the artillery, or even to defend against the attack of the artillery?

You must know that although the current Lujiang River is obviously ahead of other players in the Huaxia region in terms of military technology, Lujiang itself is also a part of Huaxia.

The same script is used here as in North China, Jingnan, even Shuchuan, and the Western Regions, and the languages ​​are not much different.

This is not like the relationship between the Han Dynasty and the Western Regions or the Fusang Kingdom in the east. When everyone speaks the same language and uses the same script, it is almost difficult to guarantee that the technical secrets will not be leaked, let alone achieve it with others. There will be a huge gap like a technical barrier in later generations.

Although the current artillery has not officially appeared on the battlefield in China, both Zhang Yan himself and the group of generals under him can be sure that once the artillery appears on the frontal battlefield, those people of insight will be the first After receiving this news, those powerful rulers such as Yizhou Mu Liu Yan and others will also conduct experiments in this area within their own territories.

Don't look at the artillery, which looks quite amazing, but to be honest, if those large Chinese warlords want to imitate it, it's not too difficult.

Maybe one day, the weapon Zhang Yan invented in China will fall back on his own head.

As for if it really comes to that time... He has to find a way to face it anyway, right?

……

All in all, whether it is Zhang Yan or the group of people below, in fact, after getting the cannon, the king of war whose power is far superior to all contemporary weapons, they subconsciously raised their imaginary enemy to more than one level.

This kind of thought was out of control in their minds, and some of them even went to visit Lu Su in the barracks.

As for Lu Su... He was originally a warrior with a mind full of "gesturing and gestures". After hearing the alarmist words of those lunatics in the technology department, he actually believed a lot. He simply waved his hand and commanded Lujiang soldiers The company's trip was delayed for another two days.

These two days were just enough time for them to use the weapons of Lujiang Bingmasi to test the cement building materials.

If you talk about the most powerful one among the three armies in Lujiang, it is without a doubt the Lujiang Military and Horse Command, which was established the earliest among the three armies.

On the one hand, the predecessor of the Lujiang Bingmasi was Zhang Yan's direct army, and he traveled with him for more than a year, but also experienced a lot of battles.

On the other hand, because the metal output in Lujiang is still limited, and the Huainan Industrial Zone has not yet been fully completed, nine of the ten cannons currently cast in Lujiang are limited to this one. The strongest army.

As for the highlight of everyone's testing of cement this time, it is to use cement to build semi-permanent fortifications, and to test the defense performance of such fortifications in the face of attacks from various weapons.

From the simplest chopping with swords, to stabbing with spears, and shooting with bows and arrows.

From crashing cars, the direct impact of battering rams, to long-range projections using thunderbolts - aka trebuchets.

The results of these tests will be recorded by the Lujiang Science and Technology Department and appear on Zhang Yan's desk as reference data.

At the end of the experiment, the so-called anti-strike ability in the most extreme state naturally refers to the bombardment of the entire fortification with the existing Type [-] artillery.

I have to say, these people are really a bunch of lunatics.

……

Time passed, and when the sun gradually rose, all the people present were almost there.

Seeing that everyone was seated one after another, the researcher in charge of the experiment today glanced back at Ma Jun, exchanged winks with him, then turned around and announced to everyone that the experiment will begin immediately from now on.

……

To be honest, compared with the previous experiments, this experiment is much better than before in terms of scale, process, and even the number of control groups.

Moreover, the venue this time is also more spacious than before. There are more than a hundred people staying here before and after, and it doesn't feel crowded at all.

What was very careful was that since the highly dangerous equipment such as artillery was going to be used this time, on the school grounds, everyone also temporarily built a terrace, which was specially used by Zhang Yan and other officials of various departments in Lujiang.

It can be seen that on the terrace, there are even special viewing seats and waiters, and the view of everyone is better than that on the flat ground.

A large number of cement and concrete fortifications arranged in advance are located on the opposite side of the terrace, and in front of the terrace, with their backs facing everyone, is a row of artillery arrays covered by red cloth.

The previous tests are all things that have been tested, such as the ability to withstand pressure and strength. Although Zhang Yan also knows that these data are very important, they are all things that have been played after all, and they are not very interesting to Zhang Yan.

During the whole morning of the experiment, Zhang Yan sat on the built terrace, looking a little drowsy.

But soon, after having lunch at noon, this test officially entered the topic: that is the test of the resistance of cement fortifications to the weapons of the Chinese Army today.

Chapter 48 Tears of the Times

The first to appear is the cold weapon.

Swords, chain hammers, bows and arrows, and even the battering hammer used by Zhang Yan and Jian Shuo when they were singled out, these are all very common weapons on the battlefield of China.

However, in this experiment, these weapons that could cause huge casualties to the soldiers obviously did not have any significant effect on the inanimate substance like cement.

Whether it is chopping with knives and swords, or organizing large-scale archers to shoot salvos, these metal weapons hit the solid walls of the cement fortifications, just like those walls made of stones, they can only cut out one after another. Blinding sparks come out.

Even if the soldiers wielding their weapons use too much force, the best blade will quickly blunt or even roll when it is cut on the cement, and what is left on the cement wall is only a light white mark.

Among the many cold weapons, the only one that played a little role was the battering hammer that Zhang Yan had used.

……

"preparation--"

"Smash!"

……

Following the order of the experimenter, an extremely burly soldier swung a battering hammer, and smashed it against the concrete wall with his head covered.

Although most of the infantry in Lujiang's current array of soldiers use one-handed knives and round shields, just like siege vehicles, battering rams are only used during the siege of the troops. A city-breaking weapon distributed by troops to front-line soldiers.

And this kind of weapon is often only qualified to be used by extremely strong people like the soldier just now.

……

"drink!!!"

"boom--"

……

Accompanied by the soldier's roar, the hammer head made of pure metal slammed into the concrete wall not far away with lightning speed.

The dull sound from the collision between the two made many soldiers on the front line near the experiment site tremble, and focused their attention on the direction the soldier attacked just now.

It's just a pity that although the hammer was powerful and scattered a lot of cement debris, when the smoke and dust gradually dissipated, there was only a shallow pit left on the scene.

……

"Ugh……"

……

Seeing the result of that hammer, many soldiers present sighed subconsciously.

You know, what the battering hammer can do just now is already the strongest destructive force that infantry like them can do, and this is just a small hole left on the concrete wall. .

No, maybe you can put it another way.

……

"The two-handed hammer successfully destroyed the concrete wall and left a mark on it that could not heal."

"Before this, whether it was a sword or a crossbow, they couldn't even leave traces."

……

Different from the infantry who were tested on the front line, after the results of the first round of cold weapon tests came out, a faint smile appeared on Lu Su's face at the rear, and he even had a tendency to spread further.

You must know that regardless of whether this kind of fortification is effective for higher-level damage, the fact that it is almost invincible to cold weapons alone has already proved its value.

Imagine that if an army is fighting another army in the field, the two sides should have killed you and me, and it would be a [-]-[-] encounter.

But at this moment, one of the two soldiers suddenly used a magical material to build the city overnight.After one night, the city rises from the ground, and the battle between the two sides is no longer a level.

In the case of little difference in troop strength, the side with fortification cover is almost invincible.

Not to mention that Lu Su is still thinking about what kind of changes such a thing can bring to future wars. Behind those arrayed soldiers, another group of people is already eager to try.

Compared with ordinary array soldiers, their attack methods are more diverse and complex, and their lethality is far more than that.

In the eyes of these people, it is obvious that the cement wall not far away is completely the standard of a city wall. If you want to deal with the city wall, you must use their method.

The soldiers before this group were all longbow soldiers, and they were also noble arms that could kill each other before the battle between the two armies.

But now, there were no professional archers in Lujiang.

They are still the strongest in the entire army formation, and they are also the team with the fiercest firepower projection.

Now, their name is Artillery.

……

They didn't use their "big treasure" as soon as they came up. The artillery battalion under the command of Lujiang Bingmasi, like those ordinary soldiers, first used the ordinary siege weapons assigned to them by Zhang Yan to conduct a test.

It is said to be a siege weapon, but it is actually something like a battering ram or a crashing car.

The results of the test were not unexpected. Although the overall force of the crash was greater than that of the two-handed hammer, the large area of ​​the crash caused the force to be scattered everywhere and not concentrated together, which did not have any effective effect on the cement fortifications. harm.

As for the battering ram... that's even more nonsense.

This thing was originally used to break the bolts of the city gates. Now everyone is using it to hit the cement and concrete fortifications whose strength is comparable to that of a stone city wall, but it's just for fun.

If you really want to pose a threat to this kind of cement fortification, you have to use a long-range weapon with a large mass projection.

It's not the cannon, it's you, Thunderbolt.

The catapult, also called thunderbolt chariot, is a kind of siege equipment that has been active in the front line of war since the urbanization construction intensified in the Han Dynasty.

Before the appearance of gunpowder weapons, the thunderbolt chariot was the strongest firepower that the Chinese army could output, and how to improve and improve the thunderbolt chariot was also a matter of painstaking consideration by Chinese craftsmen of all ages.

Although in this world line, as soon as Zhang Yan came to Lujiang, he directly produced the top-ranked substitute product of the thunderbolt car - the artillery, which completely strangled the future development of this kind of kinetic energy weapon, but it cannot be denied that the thunderbolt The car itself still plays a pivotal role in the history of China's weapon development.

Even compared with the early artillery, although the accuracy of the thunderbolt car is much worse, as long as it hits the target, the actual power will not be much different.

"preparation--"

……

"put!"

……
