In the face of such a tall wall, the Spider Tank and the Bush Warriors could not climb it, so they could only destroy the wall by attacking first. Otherwise, if you have to take a detour, you don't know how far it will be.

And this place, the enemy can attack at any time. To enter the Maro Kingdom, you must either borrow the path from the nearby Karimsi Kingdom, or you can only rush through the valley in front of you.

The last time the Maro Kingdom was able to come to Rusyala to intervene, it was because of the passage from Karimsi.

But now, Karimsi is facing his powerful neighbor, and it is absolutely impossible to use it for himself. However, because of the last extermination of the undead, the remaining remnants of Karimsi still have a little connection with the Holy Light Empire.

Even I heard that Karimsi had secretly taken refuge in the Holy Light Empire, and with the Holy Light Empire in its cover, Chi Nan couldn't destroy it now. If it had been the people of the Holy Light Empire, God knows what would have happened. Compared to the Holy Dragon Empire, the people of the Holy Light Empire are more like religious madmen, and their current strength Chi Nan doesn't want to provoke them.

So on the one hand, it developed in the rear, and the war in front could only be done through an upright attack.

"I'm going to let the pneumatic cannon go forward, and when I reach the shelling position, fire the shell at me. In addition, the Wind Cannon Spider Tank is also ready, and when the time comes, it will rush directly over and consume the defense of the city wall at close range. ”

In the rear, Holm and Moiru, as commanders-in-chief, were negotiating the battle situation. The headquarters is also a plant fortress. This plant fortress is very thick and uses a special shell that has been newly manufactured.

The blue and white painted trees are also on the ground, and the thickness is comparable to that of the city wall. With a hard shell of this thickness, even if several gold masters join forces to attack, they won't even want to break it for a while.

The order was given, and the plant weapons in front slowly dispersed, leaving only these two weapons suitable for breaking the city and began to move forward.

Today's pneumatic cannons are no longer the pneumatic cannons that needed to be pulled by horse-drawn carriages and humans. Each pneumatic cannon was fitted with a self-propelling device, which was a full sixteen thick thighs.

But even so, the large pneumatic cannon is still very slow to move. The shells fired by these pneumatic guns are not the shells of ordinary Spider tanks, but are larger.

Just looking at this bloated appearance, it may not be long before other types of weapons are upgraded, and this pneumatic cannon may have to withdraw from the stage of history.

Although he couldn't see it, Chi Nan could still imagine that kind of situation. A moment later, there was the sound of artillery fire ahead. At this time, even the reporter's voice could not be heard clearly.

All civilians turned pale when they heard these sounds, and they could also know the intensity of the fighting on the front line at this time.

Just now, the pneumatic cannon had already entered the firing range, but what I didn't expect was that the opponent's alchemy cannon also included it in the firing range. As a result, both sides opened fire almost simultaneously. A huge air explosion of the pneumatic cannon sounded, and countless shells streaked through the air and flew towards the opposite side, some falling on the city walls, some behind the walls.

These shells are no longer the original fire oil bombs or poison gas bombs, but the flowering shells of the original season.

It is equipped with bronze-level explosive mushrooms, and they are also large-scale compressed. Every time it explodes, it can produce a huge impact force, this power is very close to the destruction of the silver peak, and the range is huge.

Each explosion would weaken the light fluctuations on the opponent's city wall, and after a round of shelling, the entire city wall dimmed a lot. It was only in the next moment that the light above the city walls was restored.

There is not only one microphone in this place in Chi Nan, but two, one is connected to the reporter, and the other is a secret report dedicated to transmitting news to himself, which makes Chi Nan and others know more about the front line.

"Looking at the way they looked, they were really well prepared. The frontline city wall circle has a really large reserve of magic crystals. We don't have a large magic crystal mine in this place, so these ......"

Chi Nan's eyes narrowed slightly, and Romigala said even more disdainfully: "The Maro Kingdom is not so wealthy, this is definitely because there are people behind them to support them." Hmph, if it weren't for that bastard leaning on those people behind him, how could they possibly get into position. ”

Romelia gently pulled her sister's arm and soothed her sister's emotions. When these things happened, Romilia was young, and even now she is not very old, and she is not sensible at all. I don't understand why my sister is so angry, isn't her life very good now? As for what happened before, Romilia doesn't even think about it.

At the same time, the alchemy cannon on the opposite side also fired. But these alchemy cannons are not the pure energy cannons that Chi Nan has seen before. Come to think of it, it's also because the energy cannon consumes too much, so I can't afford to use it.

This kind of non-pure alchemy cannon is more capable of forming a numerical advantage. The news has already told Chi Nan that this kind of proximity cannon only uses the power of the magic crystal as a kind of thruster, which is similar to the compressed air of the pneumatic cannon.

And the cannonballs that come out are not special items, they are just ordinary iron balls. It's just that there are some strange runes on the surface of the iron balls, and these iron balls are actually blessed with fire-type magic. Whenever the iron ball hits the ground, the fire element will burst out, creating a huge impact in place.

The damage that this kind of cannonball can cause is actually not weaker than his own explosive mushroom cannonball, these alchemists are really not so simple, Chi Nan thought silently in his heart.

Because the front line was too dangerous, Chi Nan didn't know if the Holy Dragon Empire would specifically assassinate him, so this time Chi Nan didn't go to the front line at all, and could only listen to the radio in his room.

The chaotic explosions on the opposite side also fully illustrated the fierceness of the battle. With each attack, there will be air cannons that will be blown up, and there will also be spider tanks that will be blown up. And the other side is also uncomfortable.

Because the attack on this side will not only weaken the magic array, but every time it explodes, many soldiers will be blown away, and even the corpses will not be able to be put together. The bombs that fell behind blew up a lot of hidden alchemy cannons to pieces. These plant weapons don't cost much, on the contrary, the cost of those alchemy cannons is not simple.

It seems that the losses of the attacker far exceed that of the other party, but it is obvious that the people of the Maro Kingdom are even more distressed. And at this time, a part of the spider tanks finally broke through the blockade and approached the opponent's city walls.
