Not only did Scott feel that this wave of attacks was not powerful, but even the demons felt that Emperor Shitian's combination punch was nothing at all.

So much so that some demons even ran over excitedly, stepping on the huge meteorite, and kept screaming, as if they didn't care about the high temperature of the meteorite at all, just to release the Emperor of Heaven in one breath.

But at this time, suddenly, all the meteorites exploded violently, as if there were tons of explosives inside, and the terrifying explosion completely destroyed everything within a radius of 100 meters in an instant, even if it was a powerful silver-level demon, it was blown into minced meat on the spot.

The terrifying shock wave even hit a distance of four or five hundred meters, and everything that stood in the way was swept away, many demons were either killed or injured, and many flesh fragments even fell thousands of meters away.

This hundred terrifying explosions directly caused a hundred beautiful mushroom clouds, not only killing all the demons that approached them, but even the buildings were seriously damaged.

Not only were several towers toppled in the explosion, but even many houses were completely destroyed, and even the city wall cast by King Kong was not spared, and it was blown out of gaps several meters deep.

Not only that, but the place where the explosion occurred also left a layer of special features with extremely high temperatures, not only was the ground burned and melted, magma appeared, and even the steel city wall could not withstand the high temperature of tens of thousands of degrees, and gradually began to melt.

Although even if a gap of several meters deep is opened on the huge city wall, it is not a big problem, but the problem is that the hot lava left behind, while melting the steel city wall, also destroys the magic patterns and alchemy runes inside, making the magic resistance of the city wall greatly reduced.

Seeing this scene, everyone present suddenly gasped, none of them expected that this was a compound spell, not only a meteorite technique, but also a meteorite that had fallen, and a lava burst technique was hidden.

It is also a ninth-level spell, and the lava burst has the dual attributes of earth and fire, not only has the terrifying explosive power, but also the blown earth and stone also have the function of shrapnel, which can collapse the demons in the distance.

The most terrifying thing is the layer of magma left in situ after the spell is released, which is the interaction between the terrifying explosion and the earth, under the squeeze of ultra-high pressure and ultra-high temperature, a special high-temperature high-magic substance is produced.

The temperature of this layer of magma is definitely tens of thousands, it can easily melt steel, and the fire magic in it will continue to emit out, so that it can provide heat for a long time, which is difficult to extinguish.

Because of this, even if the steel walls are stained with this thing, they will begin to melt in large areas, thus reducing magic resistance.

Of course, the affected city wall is only a small section, and it does not have a serious impact on the frontal wall, which is often hundreds of kilometers.

But the problem is, this is only the first shelling!

In fact, before the lava burst detonated, Emperor Shitian's second salvo had already been fired.

Just as a hundred mushroom clouds rose into the air, the shells of a hundred heavy artillery shells fell again.

This time, only seventy or eighty cannonballs were stopped by the Demon Tower, and the remaining twenty or thirty cannonballs unexpectedly fell into the Demon Castle under the cover of the mushroom cloud.

At this time, the power of the 500-mm heavy gun can be regarded as fully demonstrated.

First of all, the cannonball, which weighed two and a half tons, fell from the sky at several times the speed of sound, directly penetrating the earth, houses, and even the Demon Tower, and exploded violently inside, and the terrifying explosive force could basically destroy all houses.

Even the Demon Tower, which has a relatively strong defense, was knocked down by an unlucky bombardment, and the explosion from the inside out blew it up in half, basically being scrapped.

Therefore, the next meteorite technique fell on the half-section of the demon tower without any interception, and directly smashed it into ruins.

The next lava burst was basically equivalent to whipping the corpse, and the entire Demon Tower was beaten to the point that there were no bones left, leaving only a large pit burning with magma in its place.

I have to say that Emperor Shi Tian's luck was not bad, 200 shells, only such a single shot accurately hit the Demon Tower, and the result was successfully destroyed.

Don't look at the huge 500-mm shells, it seems that the rate of fire is very slow, but with the help of powerful giants, the reloading speed of the shells is still very fast, so in general, the rate of fire of the 500-mm heavy gun is by no means slow, one shot in ten seconds.

So then, there were waves of salvos, huge cannonballs, slashing through the air with sharp whistling, frantically smashing towards the Demon Castle.

From a distance, the entire Demon Castle was targeted by Hongji's small piece, and the whole was in a state of apocalypse.

Not only was there a constant bombardment of two-and-a-half-ton steel shells, but also a large number of meteorites falling from the sky, combined with the explosions from the bursts of cannonballs and lava, and mushroom clouds, the area was in a state of terrible destruction.

A large number of houses and warehouses were destroyed, and demons running around screaming were killed and blown away, and things like catapults and magic traps were destroyed or detonated from time to time.

Even the steel walls were hit by a lot of shells, blown up into craters, and there was red-hot molten iron everywhere.

However, because the steel walls are so big, they are not only very long, but also more than 100 meters high, and the thickness is about 50 meters.

Such a thick steel wall, even if it is bombarded by 500 mm caliber heavy artillery, is only a small injury, and it is really not so simple to completely destroy it.

Even if the magic resistance of the steel wall was removed, it would be very, very difficult to open a huge gap in the steel and metal wall with such a large chunk of steel and metal wall, enough for the troops to rush in.

Emperor Shi Tian quickly realized this situation, so he frowned and issued a new order.

Immediately afterwards, the operator of the 500-mm heavy gun began to gently raise the angle of fire, no longer bombarding the city wall, but bombarding various buildings behind the city wall.

At the same time, Emperor Shitian's castle was also wide open, and elite troops began to attack one by one.

Since dozens of city gates have been left for a long time, each gate is dozens of meters wide, so although Emperor Shitian's troops are many, the speed of killing is still very fast.

And many troops did not need to go through the city gates, they flew down directly from the city walls.

Among them are a lot of alchemy wagons, all of which are pulled with 250mm heavy guns, as well as exclusive shell transporters.

Under the influence of acceleration magic, the army of more than 3 million sent by Emperor Shakti soon reached a place about 20 kilometers away from the city wall.

Then they began to stand in place and set up defenses, especially the caveman platoon gunners, who had already supported their mortars and were ready to shoot at any time.

As for the 8,000 250-mm guns, they were immediately deployed on the spot, and then immediately thrown into the shelling.

Again, their target was not the city walls, but the large expanses of buildings behind them.

With so many heavy artillery pieces joining the bombardment, the destruction speed of the Demon Castle instantly increased a lot.

250mm heavy artillery, although there is no way to take the city wall, but the buildings inside the demon castle, few can withstand it.

A single salvo of 8,000 cannons smashed 8,000 shells into the interior of the Demon Castle like a torrential rain.

Near the city wall, there was a continuous explosion sound, and immediately the whole person was covered in gunsmoke.

Emperor Shi Tian also let it out this time, and all the fire-based Burning Sun Burst Spells he used were not to kill people at all, but to destroy buildings, especially the Demon Tower.

In the face of such a dense shelling, even the Demon Tower could not support it, and it could not stop many shells at all.

The 8,000 shells were relatively dense, and they were usually deliberately aimed at dozens of targets. And after the Demon Tower is targeted, it is limited to the factor of firing range, and can only deal with it by itself, which is equivalent to facing hundreds of shells at the same time.

Under the harassment of the 500mm heavy artillery, the demon was already miserable, and now with so many 250mm heavy artillery, the demon tower was overstretched in an instant.

After barely resisting it, they were destroyed one after another.

If you are lucky, the Demon Tower will be able to survive for a little longer if you encounter a very low hit rate of your artillery.

The unlucky Demon Tower, when he met a god-level artilleryman, ate more than a dozen 20 rounds of 250mm heavy guns in a row, and he could almost be shattered.

Scott watched the whole scene from a distance, and they couldn't help but feel excited.

Scott couldn't help but say, "It seems that the battle between the Demon Tower and the artillery ended in the complete victory of the artillery. ”

"That's right, the artillery has a long range and high mobility, although the accuracy of the hit is a little worse, but as long as the scale is reached, it can still destroy the Demon Tower from a long distance. ”..

Every time I see them firing cannons, my little heart keeps trembling, where they shoot cannons, it's money at all!"

"Yes, this consumption is too great, I just calculated, 8,000 shells in one salvo, it only destroyed less than ten demon towers. God knows if the price of these ten demon towers is 8,000 rounds of cannonballs. ”

"There should be, right?" said a man next to him uncertainly.

Scott thought for a moment and said, "The alchemy cannonballs on the market, if they are 8,000 rounds, are definitely more expensive than more than a dozen demon towers. But don't forget that these shells are produced by the people themselves, and the cost is probably not as high as the selling price/0, so on the whole, people still make money. ”

"It would be nice if we could make this too!"

"In fact, Emperor Shitian's cannonballs are not expensive, they are only three times the material. Especially in our plane, there is metal everywhere, and metal materials are not worth anything at all. ”

"That's right, although we lost a lot of metal materials, but if we can exchange the entire plane, this loss is nothing. Therefore, no matter how much Emperor Shi Tian wastes, we don't need to talk nonsense, anyway, it's not that we suffer. ”

"That's right!" everyone nodded.
