The flames that were just one meter high were not too threatening for those demonic beasts that were five or six meters tall, and as soon as the "Sea of Fire" magic appeared, even the bodies of the tallest "Earth Bear" demonic beasts were wrapped in flames in an instant.

Similarly, the storm technique is also several times stronger than the multiple wind blade technique, and the fire borrows the wind, and the wind helps the fire, and the storm makes the temperature of the "sea of fire" magic even higher, and the magic beasts with high magic resistance are beginning to be unable to withstand it.

Since the sea of fire was together, those demonic beasts three kilometers away were stopped from charging forward, although the intelligence of low-level demonic beasts was not high, but they also knew the danger ahead, and no demonic beast would automatically come into the sea of fire formed by magic.

Many water-based magical beasts stood in front, and various water-based magic began to spray into the sea of fire, and when the two magics collided together, a large amount of mist emerged.

The temperature of these fogs is also extremely high, and ordinary people can't bear it at all, but the demonic beasts don't care much, although they are a little obscured from view, but they still rush forward while opening the way with water-based magic.

It's just that what they didn't expect was that the two magics of the Sea of Fire and the Storm Spell would last so long that they seemed to be going to be used forever.

It is impossible for the magic beasts themselves to last too long, a magic can last for a few minutes, of course, this is also related to the strength of their level, and the magic cast by high-level monsters will of course take a little longer.

However, the magic source cannon is different, in the past, when the magic source essence was lacking, no one was willing to use it like this, but now that the magic source essence is not lacking, it is time to test the limit of what the magic source cannon itself can bear.

For about half an hour, the "sea of fire" continued, but the old magic source cannons that used the "Blazing Plains" had already found a very loud "buzzing" sound, and the officers could only stop using them.

Although there is no "Burning Plain", the "Sea of Fire" is a fifth-level magic, and the power has not decreased much, but because of the quantity, the coverage has been somewhat reduced.

It's September now, and it's just entered autumn, but the residual temperature of summer hasn't dissipated, even if the soldiers are standing on the nearly 100-meter-high city wall, the temperature of the sea of fire below still makes them miserable, everyone is sweating profusely, but they can't retreat, they can only suffer here.

As soon as the Demon Source Cannon of the "Flame Burning Plains" stopped being used, the demonic beasts began to attack forward again in the gap between the sea of fire, and the demonic beasts that had just attacked were almost dead, but the group of black-pressed low-level demonic beasts in the rear still had no end in sight.

"Change the magic, let the sea of fire stop casting first, and give the magic source cannon a little time to recover. Asa was also covered in sweat from the heat emitted by the magic below on the high platform, and seeing that the new Demon Source Cannon was a little difficult to support, he simply stopped insisting and let the second echelon of the Demon Source Cannon start to attack.

The most suitable magic for the Demon Source Cannon to attack is fire magic, followed by wind magic, and then ice magic.

Earth-based magic focuses on defense and is not suitable for making magic cannons, so it is not made.

And fire magic and wind magic are enough to coexist, but they are counterproductive with ice magic, therefore, the first echelon of magic source cannons are wind and fire, and these two types of magic source cannons are used to a certain extent, and they are replaced by ice magic magic

This was also planned before the war, and it was done before, but the two spells were used alternately for a relatively short period of time, and a single cast like this would make the battlefield burn for half an hour.

The power of pure water-based magic is not too great, but the combination of water-based magic and chaos magic-ice-type magic, is very different.

Chaos magic is a panacea, and it will have different effects when added to the magic of any department, like the pseudo "thunder and lightning" magic created by Mr. Algernon before, which is a combination of wind, water, and chaos.

Those who can practice ice magic, of course, must also have the magic talents of water and chaos, and according to their own talents, they also have a certain bias towards the cultivation of ice magic.

For example, if you have a high talent in water-type magic, you will practice magic such as "Ice Arrow", "Hail", and "Ice Armor", while if you have a good Chaos magic talent, you will practice "Ice Blessing" and "Absolute Zero", which are magics that use temperature as the main means of attack.

And these ice-based magic cannons are the "Frozen World", a large-scale ice-type magic that is slightly more chaotic.

This magic is filled with water elements, and then the chaos element regulates the temperature, which is not as violent as fire magic, and the damage to the enemy is not too heavy, but it has a great effect on delaying the enemy's attack.

The order was delivered, and the attacks of the last few demon source cannons of fire and wind magic came to an abrupt end, and the demonic beasts saw that the flames had finally dissipated, and despite the high temperature of the ground that had been burned to some crystallization, they began to rush towards the city wall again. bar

But as soon as they rushed to the base of the city wall, suddenly the air was hazy, a large amount of water vapor appeared for no reason, and then the temperature dropped rapidly, and the ground that had been burned and crystallized before began to crack in a large area, forming deep trenches one after another.

The water vapor was condensed into fine ice particles in the air and fell, more and more, more and more, as if it were snowing, and gradually, the ground began to accumulate and turn white.

From extreme heat to extreme cold, even those rough-skinned and thick-skinned demonic beasts were a little unbearable, and the inside of the body accumulated a lot of heat when it was roasted by fire, but under the sudden drop in temperature on the outside, under the internal and external attacks, it was extremely painful, and I truly realized what is called the two heavens of ice and fire.

And as the temperature continues to drop, the body becomes more and more disobedient, and the already not very bright brain seems to be frozen, and it is even more sluggish.

This was just the beginning, and the offensive of the Warcraft seemed to be slowed down several times, and as time passed, the fifth-level magic of "Frozen Heaven and Earth" began to truly show its power.

The fine Xiaoice grains formed by water vapor have become a thick layer on the ground, and the small body and low magic resistance of the magic beasts have been completely frozen in place, and they cannot move forward an inch, only those who are relatively large in size, or have relatively high magic resistance, are still struggling to move their limbs forward, but the speed is already much slower than just now.

The vitality of the Warcraft is extremely strong, don't look at being frozen in place, but it will not die for a while and a half, just can't act, some fire Warcraft began to use flames to resist the cold, but they are only able to melt a small part of the surrounding Xiaoice particles, which has little impact on the entire battlefield.

Since the ice magic and fire magic are relatively mild, they have lasted a lot longer, and the first magical beasts under the shroud of magic have already been frozen to the point that they can only stand in place, and more magical beasts in the rear are stepping into range.

As a result, the low-level demonic beasts gathered more and more, and they had reached the point where there were no gaps, and these demonic beasts were not able to attack, and they ran slower and slower in the middle of just three kilometers, until they were completely frozen and could not move.

An hour has passed, and the ice-type demonic source cannon has almost reached its limit, making a buzzing sound, and Asa saw that the demonic beasts had almost gathered, so he ordered again: "Change the fire-type magic again, this time you can burn a lot of demonic beasts!"

"Hahaha" The generals and archmages who were protecting him next to him burst out laughing.

The magicians on the human side haven't made a move yet, but with the power of the cannon and the magic source cannon alone, they have killed and injured tens of thousands of low-level demonic beasts, which makes everyone very happy.

Of course, I am happy, but it is also distressing enough, the shells of those heavy cannons have not been replenished so far, and the magic essence used by the magic source cannon is also being consumed in large quantities, and the glass tank containing the magic source essence has dropped by nearly a centimeter.

The capacity of one essentia jar is roughly equivalent to a hundred essentia ampoules, and the magic essentia of this jar is equivalent to the storage of ten essentia jars.

That is to say, half an hour of fire-based magic and one hour of ice-based magic, but in this hour and a half, the magic essence equivalent to more than a dozen essentia ampoules was consumed.

Now there are more than 1,000 Demon Source Cannons on the battlefield of Dukemahon, and each Demon Source Cannon consumes more than a dozen essentia ampoules, how much is this?

That is, the soldiers who controlled the magic source cannon did not know how precious the magic essence was at the beginning, if it was controlled by a magician, even if they already knew that the magic source essence was now extremely abundant, but the habits they had developed over the years would still make them tie their hands and feet, and they were reluctant to use it without scruples.

After an hour of recovery, the fire-based magic source cannon was almost intact, and after being pushed to the pass of the city wall again to connect to the magic essentia, the raging flames once again appeared within three kilometers of the Dukmahon battle line.

The damage caused to the demonic beasts this time was much greater than the first use, and although those demonic beasts were not dead, they were frozen to the point that their bodies had suffered a lot of injuries, and they couldn't even move a step, and could only watch the flames several meters high drown themselves along with their surrounding clans.

A large amount of water vapor rose into the air again, and the dense demonic beast had no longer any resistance, and could only let out a last miserable howl in the flames, and it was reduced to ashes.

I don't know if the low-level demonic beasts behind were frightened, or if they received some orders, although they gathered more and more, they no longer dared to step within three kilometers of the battle line wall.

They didn't dare to advance, but the heavy artillery began to fire again. After nearly two hours of more than 10,000 people replenishing the city walls, the shells of the heavy artillery have returned to their pre-war numbers.

And the members of the artillery squad have almost recovered their strength, so the sound of "boom boom" resumes.

The heavy artillery shells can hit five kilometers away, and those demonic beasts dare not advance, so they can only stack in the rear, and this shelling, I don't know how many demonic beasts died in this way.
