"Launch!"

With a loud roar, a massive steel chariot emitted white light from its thick cannon muzzle and shot fiercely towards the swarthy wall in front of it.

The light was so bright that it was almost impossible for everyone's eyes to look directly, and in the dark space, the damage of the light was even more obvious.

Seeing this light coming, the defenders on the wall of the Black Iron Pass were obviously panicked, and many people ran away from the battlements one after another, finding a hidden place to hide in.

There was a loud bang, and the pillar of light did not shoot down the city wall, but shot into a brilliant light curtain. But even though the pillar of light was blocked by the light curtain, the shock wave of the explosion still caused the defenders on the city wall to tremble.

Seeing that the defensive magic array was blocking the laser attack of the gray dwarf chariot, a poison-eyed officer on the city wall wiped a handful of sweat from his head with his tentacles and shouted to the soldiers next to him to prepare for a counterattack.

Not far from the steel chariot, two gray dwarves were watching the lightning cannons bombard the walls of the Black Iron Pass.

"Their defensive magic array is still a lot better than Helmark. ”

Said a gray dwarf clad in full-body scale armor.

Another gray dwarf wearing a horned helmet nodded and said, "Yes." However, if we continue to attack like this, we will definitely be able to shatter their defensive barriers, and at that time, this place will not be able to stop our artillery fire. ”

"However, they must have other means of fighting back. ”

The gray dwarf in full scale armor was a little worried, and as soon as he finished speaking, he saw a magic shoot from the distant city wall, and the target was obviously a steel chariot.

"Oh no! their magicians are fighting back!"

The gray dwarf in scale armor was shocked.

Seeing the appearance of this magic, it is obviously a thunderbolt magic, and the steel on the steel chariot has excellent electrical conductivity. If it is allowed to hit, those warriors inside the iron house will definitely be hit hard. The defenders above the Black Iron Pass were obviously sharp-eyed, and they discovered the weakness of these steel behemoths in the shortest possible time, and launched a counterattack.

"It doesn't matter. ”

His compatriots laughed.

His companion's words were clearly beyond the expectations of the scaly-clad gray dwarf, and he couldn't help but be stunned for a moment, and at this time, the thunderstorm spell that kept exploding had already crashed into a steel chariot that had just finished firing rays. He only heard a loud noise, and the scaly gray dwarf screamed in his heart, but then he was stunned, it turned out that the appearance of the swarthy steel chariot suddenly glowed with a light, blocking the thunderstorm technique from the outside of the steel chariot. When the thunderstorm passed, the steel chariot did not lose a single cent, and after a while it continued to fire.

"Hmph, they think they have a defensive magic array, don't we have one?"

And at this moment, the gray dwarf with horned steel helmet sneered.

It turned out that since Sun Licheng smashed the two steel chariots with the magic crystal cannon, the gray dwarves had a careful analysis with the dark elves, and finally came to the conclusion that the steel chariots must strengthen their defensive forces, especially the kind of magic that can be transmitted into the vehicles, such as flames and lightning strikes, must be strictly guarded.

In the end, they came up with a plan to have the Dark Elf mages engrave a lot of magic runes on all the steel chariots, and when the chariots were attacked by ranged magic, they could activate the defensive magic array to defend them. At this time, this magic defense magic array began to work under the attack of the army of Zerata City.

Seeing the effect of the defensive magic array of the steel chariot, the morale of the gray dwarves next to them immediately skyrocketed, and they began to frantically add the energy generated by the magic furnace to the lightning cannon, and fired at the black iron gate with all their might.

The gray dwarfs were greatly emboldened, and when the Black Iron Pass saw that the magic attack did not work, the defenders immediately fell silent, and many felt that a large stone was pressing on their hearts. It is difficult to destroy the opponent's long-range attack with a counterattack on his side, if he can only be beaten passively like this, in the long run, even if the city wall is tall, how long can the Black Iron Pass last?

Just when everyone was worried, they suddenly heard another officer shouting: "Launch!"

With his order, several loud roars rang out at the head of the Black Iron Pass. The roar was so loud that the unprepared defenders immediately covered their ears like thunder.

Some of the powerful warriors were not affected by the roar, and they hurried to look and found that it was three large iron balls flying towards the enemy's position.

"What's that?"

Seeing something coming out of nowhere, many gray dwarves had questions in their minds.

The iron ball seemed to be very slow, but in fact it was far faster than the galloping horse, and in a short time it smashed into the body of a steel chariot. This time, the defensive magic array suddenly flashed again, but the huge impact still caused the entire magic array to shake violently.

"New magic?"

Seeing the steel chariot hit by something powerful, the two gray dwarves just now were immediately shocked. At this time, the artillery on the head of the Black Iron Pass City rang out again.

With the roar, countless large iron balls rained down on the heavy equipment of the gray dwarves, even if the defensive magic array successfully intercepted these iron balls, but everyone could clearly see that the brilliance of the defensive magic array on the chariot had dimmed, and everyone estimated that if it continued like this, the defensive magic array would definitely not be able to support it for a long time.

How could they have so many mages?, looking at the number of lights on the walls and the iron bullets flying in, the gray dwarven officer was horrified.

Seeing that the artillery given by Sun Licheng had an effect, the defenders on the wall of the Black Iron Pass immediately cheered, and the two magic apprentices also made persistent efforts and began to shoot magic into the distance.

In this way, with the help of firearms, Black Iron Pass actually fought with the gray dwarves with long-range weapons, making the gray dwarf army full of confidence disgraced.

Three days later, in Helmark, the city lord's palace, Ardabisiah sat on his throne with a frown, and beside him were a group of dark elves and gray dwarf officers.

"Augusta's offensive was frustrated. I don't know where Zerata City got a powerful weapon that can shoot large iron balls far away and cause huge damage, and the magic array on those steel chariots can't resist it. Under the bombardment of the huge kinetic energy of those iron balls, the magic array will not last long before it will fail, and the steel chariot exposed under the iron balls is very fragile in the face of the magic and iron balls on the black iron gate, and it will be destroyed and killed if it can't hold on for a few times. ”

In the middle of the hall, there stood a gray dwarf soldier, who was reporting loudly to everyone.

"When did those creatures in the dungeon have such powerful weapons?"

A Dark Elf officer asked in surprise.

The others nodded after hearing this, in the underground world, the dungeon creatures and the dungeon creatures have been facing each other for countless years, and the two sides can say that they know the roots, what weapons the other party has, and what kind of solution there is after encountering it is very clear. But this kind of sudden appearance, the device that can launch the iron ball is neither a trebuchet nor magic, the iron ball is very heavy, the trebuchet can't be launched that far, and the power will not be great, and magic needs a lot of mana to support, although Zerata City is a dungeon with good strength, it is obviously not so much mana to waste.

"It can't be reinforcements from the Mage Country, right?"

An officer said.

"No, if the people of the Mage Country arrived, then the city of Zerata would have sent troops to fight back, and that Amartyago is not a good man and a woman. ”

But immediately there were rebuttals that dispelled the speculation.

Hearing the discussion of his subordinates, Adabisiah had a bad guess in his mind.

"Could it be that Sun Licheng did it?"

He sighed in his heart.

"Well, since you're so powerful, then I can't use the same methods as before. ”

Thinking of this, he waved his hand and said, "In any case, the pressure in the direction of the Black Iron Pass must be strengthened, pass on my order, and exclude another thousand people and ten mages." ”

And in Zerata City, hearing the report from the front, the soldiers and civilians of the dungeon were extremely happy. And Amatiago immediately ordered his subordinates: "Go, ask His Majesty Sun Licheng to come over, I want to see if I can get more artillery." ”
