The direct shooting distance of the Magic Crystal Hand Cannon is one kilometer, and the extreme shooting distance is ten kilometers. However, at this distance, whether you hit the target or not depends entirely on luck.

Three kilometers is a relatively suitable distance. Apart from the same magic crystal cannon and forbidden spell, there is no other attack method to attack so far.

The God of War structure advanced to a three-kilometer position. No. 11 raised his arm and pointed at the sky diagonally. The position of the elbow expanded, enlarging the internal space of the Magic Crystal Hand Cannon. At the position of the wrist muzzle, a dazzling energy ball is rapidly forming.

A few seconds later, the position of the muzzle suddenly lit up, and No. 11's body shook. A dazzling ray of light passed through the air and followed the perfect parabola and cut into the ground more than a hundred meters away in front of the city wall.

Failed to shoot, the humans who were watching this scene with breath and calmly let out a sigh of regret. On the other hand, there were warm cheers on the side of the Black Iron City.

This is just a test shot, what's there to cheer? Rob felt a little confused. Can't even see the situation clearly in the savages in the Black Iron City? Without the defense of the energy shield, the Black Iron City cannot defend against energy attacks and magic attacks at all. Even if they fail to hit one time, they will always hit the next one. At this time, they are still on the city wall. Could it be that they are looking for death?

Through a test shot, Rob had already calibrated the target, and then the muzzle of No. 11 raised a little height. At the same time, all the God of War components lined up with No. 11 also raised their magic crystal hand cannons at the same time. They kept the same distance as No. 11 and aimed at the city walls in the distance.

The effect of the ten-cannon volley was very dazzling. When the pressure of the energy cannon ejected from the bore was collectively expanded, a frenzied airflow was stirred up by the components, and a large amount of dust was rolled up.

Ten dazzling lights passed through the air like lightning, instantly illuminating the dark sky.

The barbarians on the city wall could no longer laugh. They watched the light pass by in horror, and then their eyes lit up. At that last moment, they could only see themselves and their companions around them, split into pieces in the strong light.

It almost formed a huge explosion, and the area of ​​the city wall was completely engulfed by strong light, flames, and plasma.

Many humans have seen the power of magic crystal cannons, but they have never seen so many magic crystal cannons fire at the same time. Even if they are four or five kilometers apart, all humans can still clearly feel the power of the cannon fire, and the entire earth is trembling.

Sure enough, the power of the magic crystal cannon is not something that matter can withstand. Without the protection of the energy shield, the city wall will be knocked down soon.

The power of the magic crystal cannon volley shocked humans and frightened the barbarians. The barbarians in other areas were stunned for a while after seeing the situation here, and almost turned around and ran under the city wall.

"This... this is simply a moving magic crystal turret... "Fulisuo, who intuitively observed the changes in the entire battlefield through magic projection, couldn't help but sigh. Although the name is called the Magic Crystal ‘Hand’ cannon, this ‘Hand’ is all ‘Hand’ of the God of War structure six or seven meters high. Its size is not smaller than that of the magic crystal cannon used by humans, and its power is naturally not inferior.

Moreover, the technology of the magic crystal hand cannon is imitated by goblins, and its power is greater than that used by humans. It is naturally normal to scare humans silly.

Taking this opportunity, Audrey called out the names of several officers. The officer who was called out immediately rode back to his team. Not long after, several large square formations began to slowly press towards Black Iron City.

The launch of the Magic Crystal Hand Cannon continued. After the front row of the God of War components fired, the back row of the goblin structure also raised its arms, maintaining the same angle as the front row of the structure and firing it volley.

The previous wave of strong light plasma had not dissipated yet, and the next wave of shells shot again, and the even more dazzling explosion swallowed the city wall again.

The explosion shattered the huge stone bricks on the city wall and exploded away. Even the city walls that were not directly hit by energy bombs on both sides for the time being, the stone bricks were shattered and fell off, revealing the gray-brown iron wall core under the stone bricks.

The reason why Black Iron City can be called a strong city is that a small part of it is "hard". In this world with highly developed magic civilization, the city walls made of bricks and stones are simply fragile. A ground-sinking technique traps a pit under the city wall. The natural weight of the city wall alone can crush the entire city wall.

In order to make the city wall stronger, the construction of the city wall must adopt a more effective method, among which the stone iron core is the most commonly used method. First, the stone fire-resistant brick and stone sun carved magic runes, built two stone walls, leaving a middle position. Then cast iron water in the middle position to fill the gap between the stone walls.

In this way, the iron core is cast. After being cast one after another, the iron core of the city wall is formed into a string. The runes carved from the stone bricks are carved onto the top after the iron core solidifies, which is equivalent to another anti-demon treatment.

Then another layer is wrapped outside the stone bricks, and then the hollow position is filled with iron sand, gravel, etc. to prevent the magic.

The city walls built through so many processes can withstand the bombardment of magic below level seven. If combined with the energy barrier opened by the magic tower in the city, as long as the number of defenders is not too small, or the commander is too idiotic, it is impossible to fall.

Unfortunately, fortresses are often broken from the inside.

Now, the energy barrier in the city has been destroyed in advance by Audrey when she retreated, and the city wall is directly facing the bombardment of the Magic Crystal Hand Cannon.

The seemingly indestructible iron core is constantly distorted, deformed and melted under the constant bombardment of energy cannons.

The city wall has been treated with anti-demons, but the magic crystal cannon is not a magic attack, but an energy attack. A large number of elements gather into energy groups, releasing huge impact and high temperatures at the moment of collision. Almost nothing can be immune to the destructive power generated.

After ten rounds of alternating volleys of the God of War and the Goblin structure, the next wave of volleys actually shot through the location of the city wall and hit the building behind the city wall.

No.7, where Rob is located, immediately raised his arm to signal. Seeing his gesture, the goblin structure in the back row immediately stopped shooting. Before that, the God of War structure in the front row had stopped. Their souls had a deep connection with Rob and accepted orders faster than anyone else.

The strong light, plasma, and flames dissipated. The section where the city wall was bombarded was as if it was chewed in an invisible mouth and completely disappeared.
