The "lucky" low-level demonic beast that was not killed by heavy artillery shells on the five-kilometer dividing line before was unlucky enough to become a minewalker when charging towards the battle line, and was blown up by the densely buried "iron lump" mines in front of the city wall, and it became a blood mist in the sky without even screaming.

It's just that in this way, because there are relatively few low-level demonic beasts that can come over, it makes the range lethality of the "iron lump" useless, and the explosion of "boom" only blew up a few magical beasts that survived the artillery fire, and the power of a single mine that can kill and injure dozens of hundreds of demonic beasts is much smaller.

After the firing frequency of the artillery decreased, a large number of low-level demonic beasts began to pour towards the city wall, because more than half of the mines had been detonated, and they became somewhat unimpeded.

The second emperor's uncle, Asa, has also come to the city wall, he is the commander-in-chief of the Duk Mahon front, so he naturally wants to go to the battlefield in person, of course, except for some generals, almost all of the people around him are great magicians.

Seeing that the pre-buried mines near the city were a bit "wasteful", he frowned and ordered the generals beside him: "Order, the Demon Source Cannon is ready, and when these Demon Beasts attack the city, use fire-based magic." ”

"Yes!" a herald next to him immediately walked from the main station into a makeshift command room below, picked up a telephone set prepared here, and dialed it.

In the past, it took several heralds to shuttle back and forth between the city walls, and it took a long time to convey orders to officers in various sections, but now it is convenient for him to have a telephone, and the speed of delivering orders is much faster.

It's only three or five kilometers, and the speed at which the demonic beasts run is only about ten minutes, and this is still the demonic beasts that run too fast and are a little frightened by the explosion of the mine, otherwise the speed will be faster.

With a sound of explosions, the low-level demonic beasts covered the land directly in front of the Duk Mahon battlefield like a tidal wave, and the soldiers were finally able to clearly see the appearance of the demonic beasts.

These demonic beasts are probably composed of more than a dozen races, with different shapes, and their body size is not huge, the highest is five or six meters high, standing on the wall of nearly a hundred meters and looking down, it is not so scary.

When it was close, the heavy artillery lost its advantage, and Asa simply ordered the gunners to take a break, he had already seen from the main platform that the gunners were too tired to do anything, and if they continued to persevere, they were afraid that there would be an accident.

The reason why Warcraft are called Warcraft is because they can cast magic, and most of the offensive magic of humans is earth, fire, water, and wind, and order and chaos are auxiliary magic talents.

Order magic can also spawn psychic magic, while chaos magic doesn't have any powerful and lethal skills except for combining with other types of magic.

As for special magical talents such as life, plants, and undead, it is not included, because there are too few people who can have special magical talents, and they are just an exception, and they cannot cover the majority.

However, the magic of Warcraft is strange, they do not have their own cultivation system, and they rely entirely on their talent and environment to obtain the ability to use magic.

Even though the original human mages were inspired by the magic that Warcraft could perform, there were still too many weird and unbelievable magic that appeared on Warcraft.

For example, some poisonous magic humans can't refer to it at all, such as magic lizards and demon scorpions, which either live in a natural world full of poisons, and over time naturally have this talent, or their own species are born with the ability to secrete toxins.

Of course, human beings can't secrete toxins on their own, and if they go to that kind of place full of toxins to cultivate, it is estimated that they will be poisoned to death in a short time, so there have been no poisonous magicians since ancient times.

Of course, there are quite a few masters of using poison, but most of them are alchemists.

When the demonic beasts approached the walls of the Dukmahon front, all kinds of magic began to show, in addition to the four offensive magics of earth, fire, water, and wind, there were also power-type demonic beasts that relied on their bodies to be strong and hit with their bodies, and even many demonic beasts tried to climb up from the city walls.

"The Demon Source Cannon is ready to attack!"

"The Demon Source Cannon is ready to attack!"

"The Demon Source Cannon is ready to attack!"

......

Seeing that the demonic beasts had already arrived in the city, the officers in each section immediately ordered the demonic source cannon to start accumulating energy.

In the past, when humans were guarding the Duk Mahon front and fighting against Warcraft, in addition to the attack of the magician, the most powerful weapon was the Demon Source Cannon. Nuwa Library

But at that time, the magic source cannon also needed a magician to control, because ordinary soldiers had no mental power, and there was no way to activate the magic device on the magic source cannon.

It's just that the magicians who came to control the magic source cannon were all relatively low-strength, but now they are very different.

Ever since Flandy invented the magic activator, ordinary people have been able to use magic weapons and equipment, and they have become demon warriors.

Since both magic weapons and magic equipment can be used by ordinary people, this magic source cannon, which is also a magic device, can naturally be slightly modified to allow them to use it to perform magic.

However, the Demon Source Cannon is too precious, there are only a few hundred of them on the battlefield of Okmahon for hundreds of years, and even these hundreds of Demon Source Cannons can only be used intermittently during battle, because each Demon Source Cannon needs to consume a large amount of magic essence to perform a spell.

But these two bottlenecks have now been solved by Flandie, first of all, the magic essentia, Vice Dean Gavin asked Flandi for a lot of magic seeds to make elemental collectors, and the magic seeds contributed by Flandi are also a small part, and those old monster-level great magicians of the magic academy have also contributed a lot.

Even Teacher Algernon contributed hundreds of his water magic seeds, and Vice Dean Gavin himself was a top wind magician, so naturally he would not be stingy, and he also contributed a lot.

Therefore, although the essence of magic cannot be said to have become a big road commodity now, it is far less precious than before, especially on the battlefield, and it is completely possible to use magic without considering the cost.

The second is, of course, the number of magic source cannons, although there are hundreds of such expensive magic devices, but they are very rare when they are allocated to the nearly 100-kilometer defense line of Dukmahon, and they can only be used in a centralized manner.

Some time ago, the large piece of the best magic crystal that Flandi found directly increased the number by nearly half, and because it was the best magic crystal used, the power was much greater than that of these magic source cannons with high-grade magic crystals, although the corresponding consumption of magic essence was also doubled, but now magic essence is no longer a problem.

It's just a pity that in addition to the need for high-grade magic crystals, the magic source cannon also needs a lot of other precious materials, even if there is no shortage of high-grade magic crystals, there are a lot of other materials, otherwise, just the large piece of the best magic crystal that was distributed to Vice President Gavin is cut, and it is not a problem to make tens of thousands of magic source cannons.

In the past, many of the magic inside the magic source cannon were the third-level magic of "Burning the Plain", because the high-level magic crystal was placed in the magic seed of the great magician, so even if the power of the magic was not as good as that of the great magician himself, it was not too much, and the power was much greater than that of ordinary magicians.

These newly created magic cannons directly increased the magic that could be cast by two levels, turning them into fifth-level magic "Fire Sea Magic" and "Storm Magic". The power has been greatly improved compared to the previous Demon Source Cannon.

It's because of the huge power, so it needs to be stored for a period of time before use, no way, the magic source cannon uses the magic seed of the great magician, if it is used by the great magician himself, the magic seed absorbs the magic elements of nature, and it can be instantaneous.

Almost all magic devices cannot directly use natural magic seeds, because natural magic seeds are too active and can easily cause damage to magic devices.

However, the magic elements in the magic essentia are inert, and they can only wait for a while for the magic seeds in the magic crystal to absorb and arrange the inert magic essentia before it can be cast.

However, the time to store energy is not long, that is, between ten seconds and half a minute, that is, the new magic source cannon will take longer because it is more powerful.

The red light of the fire system, the blue light of the water system, and the yellow light of the wind system shone on the three or four hundred magic source cannons in the middle of the battle line, and then a large area of magic took shape in the open space outside the city.

Although the Demon Source Cannon is called a cannon, it has no cannon holes, and of course there are no cannonballs, but a solid metal column composed of various magical metals.

Casting magic does not have the earth-shattering sound of artillery, only by listening carefully can you hear a buzzing sound, this buzzing sound will slowly increase as the magic continues to be cast, until it reaches a certain level, which proves that this magic source cannon has reached its limit and must stop magic.

All kinds of magic began to rage outside the city wall, starting from the foot of the city wall and extending to about three kilometers, all of which were shrouded in magic.

The flames on the ground soared up more than a meter high, this is the Flame Burning Plain, with the blessing of the multiple wind blade techniques of wind magic, these low-level demonic beasts have nowhere to escape, and can only rely on their bodies to carry them.

However, the magic cast by the magic source cannon is continuous, as long as the cannon itself can withstand it, and the magic source can be supplied, the magic can be continued.

Burned and cut by the ubiquitous blades of wind, the monsters felt as if they were going to hell, and the roars caused by all kinds of pain were terrible.

In just a few seconds, there were many low-level demonic beasts that were swallowed by the sea of fire, and when those demonic beasts with relatively high magic resistance were struggling, the real "sea of fire" came.

The fifth-level magic "Sea of Fire" itself is an upgraded version of the third-level magic "Burning Plain", which is more powerful and has a higher temperature, and the flames that emerge have changed from red to white, and the flames have changed from more than one meter to about four meters.
