Of course, Grimg also knew the power of the dwarven artillery, so the first and even second rows of siege towers were all to help the Behemoth units resist the damage of the artillery.

"Boom!" The time for the dwarves to reload a cannonball is definitely shorter than that of the human artillery, and the second round of firing will sound again after five or six seconds after the first round, but this second round of artillery is not aimed at the giant beasts that have fallen out of the orc warriors at all, the target is still the siege tower, the sound of wood bursting is endless, and at least more than a hundred siege towers will be destroyed by an artillery attack on the periphery of the city.

"Buzz!! Airplanes!!! Airplanes!!! When the giant beast was still more than 20 steps away from the city wall (the pace of the giant beast), the dwarf officer in the city gave an order, and the heavy crossbowmen in the city shot out the crossbow arrows with thick arms in their hands at an angle of 45 degrees, and the heavy crossbow that covered the sky and the sun made a buzzing sound in the air, and directly covered the originally yellowed earth with a layer of black cloth from top to bottom. The dwarves do not worry about ammunition, and once they start, they do not stop and they will shoot at a set rhythm.

"Bang! Bang! Bang!! "There are a lot of orcs, and there are also small goblins and goblins mixed in them, and the heavy crossbow can only play a role in slowing down their charge, but not in terms of real lethality, so after two steps further, the thundering spearmen and organ cannons on the city wall began to wield their might, targeting not only ordinary orcs but also giant beasts who were about to reach the city wall.

Organ cannon, is the design prototype of the Imperial hell-level cannon, eight small cannonballs at a time, fast loading speed, long range, excellent armor-piercing ability, the giant beasts were hit by the organ cannon for the first time, blood was pouring all over their bodies, all kinds of strange screams of pain, and the orc warriors after dodging the heavy crossbow, in the face of this defense system composed of bullets, the loss instantly increased geometrically, although the heavy crossbow is strong, but the speed after ejection is not as fast as the bullet, and the shooting of the rest of the body will only cause temporary difficulties in action and hinder the effect of hindering the follow-up troops' actions, As long as you dodge this area or protect your key parts before the next time, then you can still continue to attack, who will make the orcs not feel pain.

But the bullets with accurate heads are different, on the spacious city wall, five rows of Lei Ming gunners, one shot for a row can basically ensure that the barrage is uninterrupted, and condescending, it is easier to shoot heads, not that the orcs will not block or they do not have a shield, but the power of the firearm is too great, piercing a palm is the same as playing, and the simple shield can only delay their death time, if they are swept by the organ cannon, then there is nothing to say, even the shield with the beast, fall apart together.

The three-layer defense system still failed to prevent the approach of the giant beast units, the rough skin and thick flesh were covered from time to time, coupled with the dense orcs approaching frantically, it was impossible to concentrate all the firepower on them, so about five minutes after the start of the battle, the first batch of giant beast units were already close at hand, and their task was not only to rush to the city wall (giant spider), but also to open the strong city gate or knock on the city wall (giants, trolls), after all, seven or eight hundred thousand orcs, can not rely on those tens of thousands of ladders to climb into the city.

"Iron Dragon Gunner!! Priority Araknari Spider!! Flame Cannon! Free Fire !! "According to the proximity of the giant beast units, the commanders of the four gates successively issued the order to attack the fourth layer of defense system. The Troll's Hammer Rocket Launcher is the highest military technology of the dwarves, and it is also a weapon that Zhang Hao has long coveted. The portable launcher can only be loaded with one five-meter-long conical shell at a time, and if two people work together, it can be fired once in about ten seconds, and it will take about 15 seconds for one person.

The next second that the impatient iron dragon gunner, who was standing on the high platform and waiting, heard the order, he aimed the iron dragon cannon that had been prepared at the target that had already been found, and shot out, only to hear a "hiss" sound, dragging the conical iron dragon cannon with a long tail "Bang!" A sound shot into the giant spider that crawled to the bottom of the city wall, only to see that the huge body just wanted to pounce on the city wall, the iron dragon cannon instantly entered the body from its mouth that lifted its body, only to see the giant spider's body stunning, the abdomen sank, and the next second the giant spider's whole body was about to stand up in pain, a few legs trembled violently in the air, and after a while, he directly turned over and died on his back. The iron dragon cannonball is not just a big metal stick, from the middle of it to the back, more than a dozen layers of barbs and six bloodletting grooves, either can not be penetrated, as long as it is hit, the cannonball goes wherever it is destroyed, as long as you have flesh and blood, then one shot is enough to give you most of your life, and the slightly unlucky one will be taken away directly in a wave, the disadvantage is that because of the weight of the cannonball, the range is short, the falling speed is fast, and the loading speed is slow when a person is alone.

When the iron dragon gunners began to hunt the giant beast frantically, dozens of square holes suddenly opened on the city wall three heads taller than the giant, and only to see a red door and a cannon with a flat barrel was pushed out of the hole and thrown away. The flame cannon, at the city and want to climb the city wall of the giant beast sprayed a huge temperature of flames, the giant beasts suddenly turned into a huge fireball, howling in pain, struggling on the ground, rolling, trying to extinguish these flames, but all in vain, only the burned essence light of this flame will stop, because the fire is lit only in the southern continent of the fire oil, the lethality is extremely high, but also one of the highest military technology of the dwarves, the disadvantage is that the accidental injury rate is high, the range is short, the fire oil material is precious, flammable and explosive, It can only be isolated in a separate room in the city for defensive purposes. There are only two cities in all dwarven cities that have this thing, one is the capital of Eternal Peak, and the other is this Arsenal Fort.

The behemoths covered in fire have become a major obstacle to the attack of the orcs, and the corpses of the orcs lying at the base of the city wall are burning with raging fire, where is this ladder set up, and the slightly smarter orcs will find a way to find a gap, and the stupid ones will directly want to climb onto the giant beasts and build a ladder, and the result will be burning together and turning gray together.

"Boom! Boom!! Boom!!! "The giant who was not killed by the iron dragon gunner knocked on the city gate with a big stick and mallet, but the city gate did not move at all except for a dull sound, not that the giant's power was too small, but that all the city gates had already been re-watered with molten iron for the first time, and after rapid cooling, they merged with the whole city again, and it was strange that you could knock on it with a big wooden mallet.
