As soon as the spider tanks approached, they immediately condensed the wind element, and then one by one the wind balls flew over. The wind ball slammed into the city wall, erupting with countless wind blades.

Although these wind signals are not very strong in attack power and have a short range, there is no way to adjust the angle to attack the top of the city wall. But their attacks are real elemental attacks, and the consumption of this kind of magic barrier is really terrifying.

The wind element and the earth element are originally restrained from each other, and this wall is protected by the earth elemental barrier. When encountering the attack of the wind elemental, the mana consumption rate is at least twice as fast as before.

"Damn, don't let those spider tanks continue to attack, our magic furnace is running out of hand. ”

When the commander above noticed that something was wrong, he immediately ordered an attack. It's just that at this angle, the alchemy cannon behind them has no way to attack these spider tanks, so they can only use other methods.

As a result, the two magic towers, which had been silent all along, lit up. Immediately after, the ground in front of him shook, and thorns stabbed out of the ground. The ground spike pierced a spider tank and exploded. Countless fragments scattered in all directions, smashing the other two spider tanks around them into a sieve on the spot.

The other approaching Spider Tanks, although not damaged, were not lightly injured. There was also a spider tank that had a broken leg and would not move. But after the leg was broken, the muzzle of the gun was aimed upward.

So every time the condensation wind cannon can attack the city wall above.

Several archers who were running out to attack were blown away by the wind cannon on the spot. Relying on their strong strength, several people did not die, but they were also injured. Now, no one dares to run forward.

The distance is close, the alchemy cannon misses, and it is necessary to suppress the pneumatic cannon in the distance. So the ballista carts, which had not moved, were also moved. One by one, the bolts flew out, not very far, but they could hit the tank.

The previous weapon of defending the city can now only be turned into an auxiliary tool, which makes the soldiers defending the city here feel an inexplicable loss in their hearts.

But even so, the offensive on the opposite side still did not stop, constantly rushing forward, as if they didn't care about life at all. No, it should be said that these things don't kill at all.

"Damn, these plant weapons don't have the concept of life at all, they are just plants, and they won't feel distressed if they die. Have you come up with a solution, my men will die if they continue like this? ”

In the rear, the Maro Border Command, where the commander is roaring wildly. Once upon a time, they attacked all the way to capture Rusyala's territory. At the beginning, because he was left here to guard the city, he was very angry.

Later, however, he found that few of the attackers had returned alive, and his heart turned to rejoicing. But fortunately, it hasn't been a few months since the other party called. Now it is the autumn harvest season, and the opposite side is not busy harvesting grain, but actually brazenly attacking, causing them to have no time to harvest grain.

A lot of the grain is rotting in the ground, and because of this, the logistics are even more difficult. Looking at the report every day, his heart was full of sorrow, and he would rather not have the power to defend the city on the border.

An old mage next to him said quietly: "Aren't we experimenting little by little, and this kind of thing can't be figured out immediately." And this wall was not intended to be defended in the first place, was it? ”

"Damn, you bastards, it's not you who died, you're still not Imperial Mages. ”

"Hehe, we're sent by the Mage Guild to help you, if not...... Hmph, all in all, if you don't want to help, it's the same if we change people. ”

At this point, the commander closed his mouth. They all knew that these people were sent by the Mage Guild.

The reason, of course, is to retaliate for what Chi Nan did to their Mage Association branch. Of course, on the surface, they wouldn't say that, after all, the Mage Guild is a neutral organization.

Once the attitude of neutrality is broken, then the Mage Guild will be questioned by everyone, and they will not have to develop in the future. The Mage Guild is, after all, a loose federation, not a well-structured state.

Nominally, these people joined the Maro Kingdom in their private names to temporarily help them fight. On the surface, no matter what problems arise with them, they have nothing to do with the Mage Association. However, the intensity of covert support is very large. This old mage is not an ordinary person, he is a rare gold-level mage.

"Then please ask the master to solve it as soon as possible, if the time drags on for too long, it will not benefit either of us. ”

The old mage still didn't care and said, "Isn't there still a flying boat, it's coming soon, it's better to use these flying boats to test it." If the air power can be absolutely suppressed, the Holy Tree Collar is nothing. ”

"Hmph, if you can suppress it, those people won't ...... Well, that's the end of this kind of thing. ”

The commander didn't want to continue, after all, the people of the Holy Dragon Empire behind him were not something they could talk about casually. If they heard what they shouldn't say, their Maro Kingdom clan wouldn't be able to hold on.

And at this moment, a soldier suddenly ran in and said loudly: "Report, Commander, the city wall, the city wall is about to lose its hold." We're almost running out of shards. ”

"What? Damn, didn't you say that those magic crystals could last at least half a month, not even for a day. ”

"Commander, their attack was so fierce, we didn't expect them to have such heavy artillery fire before. ”

Indeed, according to their attacks on those weapons they had seen before, they could indeed last half a month. But who would have thought that the cannonballs made of explosive mushrooms were fully equipped on the side of Chi Nan, which increased the destructive power by more than ten times.

The anti-aircraft guns that were originally used to deal with airships were useless at this time, because the airships were just watching from a distance and did not come at all. Otherwise, their walls would have lasted even shorter.

From morning to evening, the soldiers on the Chinan side were in good spirits. There is a lot of pressure from the constant dead people on the other side, but here there is only the loss of some plants, and there is no pressure at all.

"Look, there's a crack in the wall, and our attack has worked. A soldier's sharp eye spotted a crack in the distant city wall, and all of a sudden, everyone's emotions were aroused.

As a result, the firepower of the offensive side increased, which led to more pressure on the soldiers defending the city. "Oh no, the walls are about to collapse. ”
