However, gunpowder is renewable, and several garbage recycling factories can produce large quantities of nitrate powder every day, and sulfur powder and charcoal powder are not valuable items, and it is much better to use these against Warcraft than to fight with the lives of soldiers.

This is the first time that a new type of weapon, gunpowder, has officially appeared on the battlefield, and even the soldiers who planted the "iron lumps" did not expect it to be so powerful, and the huge explosion made people's ears itch a little from afar.

The soldiers had never seen it before, and those demonic beasts had never seen it, and they didn't know why they were running, when there was a sudden loud bang on the ground, and the clans in front of them flew into the sky, and their bodies were blown apart.

Although the low-level demonic beasts are not easy to use, they also know that they are afraid, but it is useless for them to be afraid, there are countless people of the same kind rushing forward behind them, even if they want to pause, there is no way except to continue to rush.

Originally, when the sea did not recede, the battle line was ten kilometers away from the sea, but as the sea receded, this channel was revealed, and the distance widened again, about 15 to 20 kilometers.

At such a long distance, those human soldiers have already buried an unknown number of "iron lumps" on the battlefield between the passage and the battle line, especially in the middle, which is very dense.

After passing through that passage, the slightly smarter low-level demonic beasts saw that the front was too dangerous, so they scattered to both sides, and only these low-level demonic beasts that were not very strong and had a bad head rushed forward without fear of death.

Although they are low-level magical beasts, most of them are around the fourth or fifth level, which is enough to be worthy of an ordinary full-body equipped demon warrior.

The lower-level Warcraft may have been eaten as food by the higher-level Warcraft last night, but there aren't many.

But even so, there are too many fourth- and fifth-level demonic beasts, and after leaving countless demonic beast corpses at a distance of more than ten kilometers, they are still so dense and black.

The corpse of the demonic beast was not wasted, as long as one of the demonic beasts was blown up and killed, or was pierced by a small piece of iron, it would be torn apart by other demonic beasts immediately, and in an instant, even the bones could not be left, and it entered the stomachs of other demonic beasts that had been hungry for a long time.

The explosions were incessant, and the generals and officers could see the scene in the distance with a telescope, but the ordinary soldiers could not see it yet.

"The gunners are in position, the gunners are in position! Ready to fight, ready to fight!" An officer with a telescope stared intently at the running monster, and when he saw that he was almost seven or eight kilometers away from the battle line, he immediately shouted into the microphone assigned to him.

The lines connected by these loudspeakers on the city walls were in sections of each kilometer, which was about the defensive area of a brigade, and the captain of the army was already a middle-level officer, commanding thousands of men.

And these soldiers in the middle of the city walls are almost all artillery, and they need unified command, so they are also equipped with a microphone.

It's just that this microphone is connected to only three or four megaphones in this kilometer, unlike the microphone in the headquarters that can transmit sound to every corner of the city wall.

For the convenience of command, this microphone is not fixed, but has a long line that can be moved with the officer for more flexible command.

"The first group of heavy artillery is ready! All the monsters in front are there, you can fire the cannons! Ready! Release!"

The officer's order came over the loudspeaker, and the gunners who operated the heavy artillery did not hesitate to release the shells filled with gunpowder.

The heavy artillery is the largest, the heaviest, the farthest, and the corresponding power is also the largest, requiring several tons of steel, even if the Ministry of Industry has obtained several mines in the Iwu Kingdom, there is a steady stream of ore for smelting, and the heavy artillery made during this time is only a thousand.

The main thing is that the technical difficulty is too great, the artillery must be successfully cast at one time, and it also needs various tests, even if it is a little unqualified, it will be scrapped, this is not a joke, in case it explodes when the cannon is fired, it is not Warcraft that dies, but humans.

Moreover, in this era of manpower, it takes one or two hundred people to work together to cast such a gun, and it takes a long time to cast it.

The time for artillery to appear is too short, and the more than 1,000 heavy guns, less than 3,000 medium guns, are already the greatest efforts that the Ministry of Industry can make, and it is also the maximum national strength of the Oskaia Empire.

With the officer's order, heavy artillery every ten meters opened fire at the same time, fortunately, these artillerymen have undergone many times of training at that artillery training ground, and they have a certain immunity to the sound of artillery.

And there are earplugs in the ears that can block the sound well, otherwise, ordinary people will even be stunned by this huge cannon sound.

"Boom, boom, boom, boom, boom......"

More than a thousand heavy artillery pieces fired in unison, thick smoke rose on the city wall, and one cannonball after another whistled out, and it only took a few seconds to cross a distance of five kilometers and explode in the middle of those low-level demonic beasts. Twenty fifty thousand

It is true that even the shells of heavy artillery are much less powerful than those "iron lump" mines buried in the ground, but although they are not as powerful as mines, they cause much greater lethality than mines.

The mine is only a one-time thing, and after it has been blown up, the ground is no longer in danger, but the shells are different, because the shells are fired continuously.

The defense of various races of Warcraft is different, some Warcraft are good at magic, some Warcraft are good at agility, and some Warcraft are good at defense, which is simply rough skin and thick meat.

Don't look at the fourth- and fifth-level Warcraft in the Warcraft Continent, it is considered a low-level Warcraft, and when you come to the Duk Mahon battlefield, you can only serve as cannon fodder, but if you are born in the Oskaia Continent, you can already be considered an intermediate Warcraft, and you need a few ordinary Demon Warriors to deal with it.

Those defensive demonic beasts with rough skin and thick flesh, as long as they don't directly step on the "iron bump", even if they are three or four meters away, even if they are blown up more than ten meters high, they will not necessarily die if they fall, at most they will be injured, and they can continue to rush forward.

But the cannonballs are different, the cannonballs flying from the sky are like raindrops, as long as they are hit by the cannonballs, no matter how strong the defense is, they are directly smashed to the point that the brains burst, the bones are broken, and the tendons are broken, plus a close-range explosion, the life is directly taken by the cannonballs.

The offensive of the entire low-level demonic beasts was stagnant, and they didn't understand why so many shells were falling from the sky, seemingly endlessly, and they were accompanied by violent explosions.

When the explosion on the ground just now, it was bearable, and it would be over after a single explosion, but this shell was endless, some were stoned to death, and some were blown up, leaving corpses everywhere.

To deal with these low-level demonic beasts, it is really easy to use heavy artillery, but it is easy to use, but the consumption is too great.

A single shell weighs fifty or sixty kilograms, and a trolley can carry a maximum of two shells.

Even if it's a magic truck, it's the limit to deliver a hundred shells at most.

From the Ministry of Works through the portal to the battlefield of Dukmahon, and then hoisted to the hundred-meter-high city wall, it requires a lot of people to complete.

Ten shots from a thousand heavy guns are 10,000 shells, and this is only shells from heavy artillery, not counting shells from medium artillery.

At the current rate of fire of heavy artillery, it takes about a minute, less than two minutes to fire one, and ten shells to fire is a matter of ten minutes.

With the development of heavy artillery, there were tens of thousands of people on the inside of the Dukmahon front to help transport shells, and the number of trucks was limited after all, and more of them were wooden wheeled vehicles that could be propelled by one person.

The corpses five kilometers in front of the battle line formed a dividing line, and a large number of low-level demonic beasts died here, but the number of demonic beasts was too large, and there were still many lucky demonic beasts that crossed this death line and continued to rush towards the Duk Mahon battle line.

The closer to the battle line under the city, the denser the "Iron Pimple" mines are buried, and these low-level demonic beasts that rush over are not having a good time, and the higher the forward the demonic beasts, the greater the chance of being killed, purely using their lives to open the way.

The war was very fierce at the beginning, and at least tens of thousands of low-level demonic beasts had already fallen as cannon fodder on the road from the strait passage to the Dukmahon front, especially within five kilometers, covered with corpses of all sizes.

On the city wall, ordinary soldiers were carrying cannonballs, and they didn't have time to look at the city, but those generals saw it really and couldn't help but sigh secretly.

Watching the shells hoarded behind those cannons quickly decrease, and then using the telescope to look at the overwhelming black and oppressive demonic beasts in the distance, I couldn't help but start to worry a little.

At the moment, there is no shortage of shells, but everyone has overlooked one thing.

It was a matter of manpower, the gunners did not have much effort, they were only responsible for correcting the landing point of the artillery shells, but the few soldiers who transported the shells from the rear of the artillery to the artillery were somewhat unbearable.

Each artillery squad has eleven people per squad, one gunner is the leader, and two deputies are responsible for loading the transported shells into the artillery.

The remaining eight members were responsible for transporting shells from the place where the city walls had been stockpiled to the artillery.

When I was training at the artillery training ground, I didn't shoot so quickly, and everyone felt quite relaxed, but when it came time to fight, even the soldiers who had been training were a little unable to withstand this high-intensity physical exertion.

At first, it was fine, but after an hour, in addition to the gunner, who was the captain, the deputy in charge of loading the shells and the team members who transported the shells were already sweating profusely, gasping for breath, and the speed slowed down significantly.

As soon as they slowed down, the firing frequency of the natural heavy artillery also slowed down, and those demonic beasts that were blocked by the cannonballs took the opportunity to surge forward in large numbers.
