In view of the great movement of the guns and cannons, the king of Xian was disturbed, and Bailiyan stuffed two balls of cotton into it.

The first thing to carry out was artillery shooting, fifty thirty-six-pound cannons fired six salvos of grenade shotguns, bombarding 10,000 clustered targets ten miles away, only six salvos, 10,000 preset targets were wiped out, drowning in the overwhelming rain of bullets and disappearing, which made Lu Gao so shocked that he broke out in a cold sweat and felt cold in his feet, and he finally understood why Baili Yan wanted to leak the news to attract the guards.

Lu Gao's previous observation of the 36-pound cannon was fired with solid bullets, and he didn't know that there were also howitzers, but now he should use howitzers, and a kill is a large area, only 50 cannons, hundreds of artillery pieces are lined up, and they don't even use the river at all, and the large battalions arranged by the guards along the river will be wiped out.

The 36-pound cannon was followed by a salvo of 100 24-pound cannons in six rounds, which also fired a howitzer shotgun, which was slightly more effective than the 36-pound cannon, so as to show the difference in power under different calibers.

Then there are five 40-pound unconscionable cannons, which will target a hundred live pigs in the enclosure.

Five conscienceless cannons fired a salvo, only to hear an earth-shattering loud noise, the fence was filled with smoke, and when it dispersed one after another, not a hundred pigs were standing, and the death was very miserable. Or the body is broken, or the skin and flesh are dying, and the best end is the seven orifices bleeding to death, the power is huge, the killing is amazing, far above the thirty-six pound cannon.

Ten 649 80 millimeters (about 72 mm) mortars were used as rapid-fire weapons, and finally came out in the finale, bombarding wooden buildings and earthen wall bunkers two miles away, and 20 salvos of 20 rounds in one minute fired 200 shells, accurately hitting the target, all of them were destroyed, and the lethal effect far exceeded all other artillery, and it deserved to be the great killer weapon of the moment.

Lu Gao, Jiao Muhua and others who saw this scene were shocked, and their faces turned pale, and Jiao Muhua couldn't help but sigh and said:

"That's a lot of power!"

Lu Gao nodded in agreement:

"Yes, I'm afraid that the guards will suffer a lot this time. Yongxing Hou, how many pieces of this cannon are there, and how far can it shoot at the maximum? ”

Bai Liyan thought for a moment and said:

"Only thirty-seven of these cannons have been built so far, and they can be doubled by July and August. However, the cannon is easy to make, but the shells and sighting equipment are not easy, so the production is not very large in the short term. Its maximum range is one thousand and one hundred steps, and the minimum is one hundred steps. ”

Mortar is the most easy to produce rapid-fire weapon in addition to gun grenades and grenade launches, which is convenient to manufacture and simple in production technology, and is suitable for a large number of military personnel with a certain amount of middle and low education.

At present, due to the constraints of production capacity, the production of optical sights for mortars lags behind, and the production and assembly of artillery shells must keep up with the installation of mortars.

Each mortar needs to have at least five or more base ammunition in reserve before it can be used in wartime, one base is about forty-five rounds, and a little less is forty rounds.

The five base numbers are 200 to 225 rounds, and even this amount, if the continuous shelling is released, it is basically only eight to 12 minutes of firing.

However, due to the limited power of the propellant, the firing range of the mortar of 80 milli caliber is only equivalent to the range of the 60 millimeter artillery gun, and this is still the firing range on the basis of increasing the firing chamber and strengthening the tail projectile body, and if the conventional charge is used, the firing range will not exceed 800 steps.

A team of 3,000 men consisting of rifles, shotguns, and sporadic short-barreled grenade launchers lined up in four rows from south to north and closely interdepended on each other, and continued to fire at an earthen wall 300 steps long and one zhang high and one zhang thick 70 paces away for five minutes.

At this time, King Xian said with anticipation:

"Aiqing, this is the new army of the widow in the future?"

"Yes, the king, these 3,000 people are veterans who have been training for two years, and more than 40,000 new weapons of various types have been produced, and more than 60,000 people have been equipped before August.

If the situation deteriorates rapidly, Yongxing can fully switch to the manufacture and production of new weapons, and with next year's production capacity, it is estimated that it will be fully transferred to the production of such new weapons, and the production of more than 100,000 such new weapons a year will be more than enough. If it is another three years, it is possible to produce two or three hundred thousand birds per year. At that time, not only the whole army can be distributed, but also local auxiliaries and county soldiers can be distributed. ”

"Oh...... This is ...... years later."

King Xian didn't dare to think about it again, and the more he thought about it, the more positive the answer was. But Bai Liyan still took the words, he lowered his voice and stepped forward and said:

"If there were no armpit people, the minister originally planned to launch two major wars in ten to twelve years after the minister was fifty years old, first to destroy the Jin state, and then sweep away the eldest grandson, and lay the situation of Xian State dominating the world in one fell swoop within 20 years, and then use eight to ten years to consolidate the country.

After a hundred years, the minister hopes that the new monarch can rule the internal affairs for ten or fifteen years, and as for whether he can sweep the world, it depends on the children and grandchildren of the king, and this is all the minister can do. ”

King Xian was very encouraged when he heard the news, smiled lightly, grabbed Bai Liyan's hand excitedly and said:

"Aiqing, don't worry, the widow's descendants will definitely get Aiqing's wish as Qing said."

While the two were talking, Jiao Muhua, who was sitting in the back row, saw some clues, and he hurriedly asked Lu Gao:

"General Lu, have you noticed that these guns can only shoot directly but not into the sky, and they seem to be closer."

Lu Gao shook his head and said:

"Otherwise, as far as Yongxing Hou knows, this gun can actually shoot into the sky like a bow and arrow, but the effect is indeed not as effective as a bow and crossbow. In addition, one of these firearms can still be seriously injured and killed after hitting a human body from 250 paces away, so it is far more powerful than a bow and arrow.

In addition, there is also a small cannon, which can hit more than 200 steps at a distance, inserted into the infantry to enhance its power, and if it is used intensively, the effect is not inferior to that of artillery. ”

In most cases, guns and bullets are fired with direct aiming, and rarely use the unconventional shooting of "beyond the firing boundary"[Note 1] to indirectly attack the enemy.

At the same time, the rate of fire of the bullet is higher than that of the bow and arrow, which is not conducive to observation, and the machine gun can still observe the landing point of the barrage, but the rifle is far worse, so the rifle rarely fires beyond the firing range, let alone the smoothbore gun.

Because of this, bows and arrows still have the advantage of attacking beyond the top compared to rifles, especially large crossbows, which are densely covered by formations, and the lethality is very considerable.

But there are two main reasons why the bow and crossbow were eventually replaced by the gun.

First, the manufacturing cycle of bows and crossbows is long, and it consumes valuable resources such as wood, and a good bow can be made by a bowsmith three to four a year, and a little worse than six or seven. Second, it takes a lot of physical effort to open a bow, especially a crossbow, so the fire output is not sustainable.

The disadvantage of the bow and crossbow is precisely the advantage of firearms, the production of firearms is only affected by the industrial scale and the number of technicians, so it can be produced in batches and standardized scale, and at the same time shooting and loading do not need to consume a lot of physical strength, and the firepower output is long-lasting, and the kinetic energy of the projectile is dozens of times that of ordinary bows and arrows, or even higher, so it is an inevitable trend for hot weapons to replace bows and crossbows.

But compared with the current firearms, although the range is a step up from the strong bow, the power is even more incomparable, but Zhiguo's Chaotian crossbow is still a huge hidden danger, and at the same time, the formation of the bow and arrow has a strategic vertical and personnel distance, so against the rifle, the rifle is still suspected of suffering.

To this end, Bailiyan has specially developed a short-barreled grenade launcher for individual soldiers, which can be loaded with 45 millimeters of grenades at a time and has a maximum range of more than 300 meters.

At the same time, the infantry formed a dense and compact formation of four rows with a unit of 1,000 people, or 3,000 people, so as to reduce the thickness of the instigal inflection, so that the coverage of the arrow array was large, and the area of the infantry line was small, and the arrow clusters could not all be poured into one line.

In this way, the long and short weapons are fired alternately forward, with guns and grenades in the distance, and shotguns and bayonets in the near distance, so that the rear follows other lines to advance alternately, and it is not even excluded that the traditional cold weapon army and cavalry formation are interspersed with the cover of the formation, so as to facilitate the transition to the hot weapon combat mode.

Despite the many benefits of firearms, there is no escaping the human resources and industrial base, as well as military tactics and technical concepts, without which guns are simply not talked.

From the beginning of the reform in 627 to the return of Baili Yan to Xianguo in 634, two things were done in seven or eight years, one was to engage in agriculture, and the other was to pilot basic education and train basic technicians in Yongxing.

In the past six years, mathematics has been promoted, standardization has been formulated, secondary education has been piloted, talents have been recruited, and power machinery and primary metal cutting equipment have been built, so as to continue to expand the scope of basic education and promote the upgrading of talents.

With the foundation laid in the first thirteen years, from 641 to this year, the industry has entered a rapid development, the talent has exploded, the scale of basic industry has grown rapidly, and the production capacity has soared.

What is more important is that the enlightenment of King Xian has directly contributed to the fact that it is today, and it is not possible for any other vassal state to do so.

After the infantry shooting drill was completed, the queue was inspected by King Xian, and King Xian also personally fired two shots, because the caliber of the rifle was large, and the recoil was greater, Bailiyan had to help King Xian to complete the shooting of two bullets, and he was addicted.

When he saw the revolver, King Xian didn't feel anything unusual, but Lu Gao was extremely sensitive and was startled:

"Da Si Nong, this gun can actually hold six bullets, and the ammunition is not soaked in water!"

"Not only can it hold six rounds without being soaked in water, but it can also automatically turn the wheel and shoot six rounds in a row."

"Shhh...... It's so powerful! Wouldn't it be more convenient to make a short gun instead of a long gun? ”

Bai Liyan shook his head and said:

"I'm afraid this is not good, unlike the rifle, the gunpowder gas of the revolver will leak, if it is made into a long gun, because there is a groove engraved in the barrel, the speed of the projectile is extremely high, and the longer the barrel, the faster the speed, the longer the projectile stays in the barrel, so the pressure of the gunpowder gas is eliminated later, so it is very easy to cause explosion, so the revolver generally does not make a long gun, unless the bullet is changed to a very small one, the gun can be made stronger, but in this way, the power is much smaller."

When the words fell, Jiao Muhua said:

"Then if the revolver can be shelled with copper skin, why can't these spears?"

Yongxing City spent three years to solve the problem of production, and the longer the copper shell, the larger the outer circle, the more difficult it is to make, and the current is still exploring the way to make, at present, there is no solution for the time being.

But don't worry, the big copper shell is not easy to make, and the small copper shell is enough. Yongxing City is developing more powerful firearms, and in a year or two, there will be a major breakthrough, when a gun can fire three to five hundred such bullets in one minute, and it will not be difficult. ”

As soon as Bai Liyan said this, Lu and Jiao looked at each other, and Lu Gao said:

"According to this, the Yongxing rifle has just come out, and it is lagging behind again!"

Bai Liyan nodded in affirmation:

"Yes, not only guns, but also artillery in the next three years is expected to be renewed, when it can be reloaded from the back of the gun, ten or fifteen rounds a minute."

[Note 1] Shooting beyond the firing range means firing the gun at a certain elevation angle, or a small elevation angle, or a large elevation angle. Shoot the gun directly at the target beyond the shooting distance, and use the principle that the higher the parabolic elevation angle, the longer the range, to indirectly hit the target.

Since the bullet is affected by both gravity and kinetic energy after being discharged, the bullet slowly falls in a low and deep trajectory, so to shoot longer distances, it is necessary to use a ruler to raise the vertical distance between the muzzle and the notch of the ruler.

If you don't have a ruler, you can only rely on experience to raise the muzzle of the gun, so that the bullet intersects with the target.

In addition, light machine guns and heavy machine guns are long-range suppressive firepower, and attacking distant targets are all muzzle-raising fire.

During World War I, rifles and Maxim heavy machine guns were widely used, raising the muzzle to a 40-degree elevation angle, covering targets two thousand meters away, and using high-pitch trajectory to increase the relative distance of a straight line.

Of course, the effect of this kind of shooting beyond the firing range is not good, and in most cases it can only rely on character, so it has been rarely used in the middle and late stages of World War I, and it is basically impossible to rely on the transcendence of firearms to hit targets in modern times, unless there is a ballistic calculation computer, such as a remote-controlled machine gun on the main battle tank.
