The siege distance of the orc army is still very far, otherwise the dwarf artillery can't only hit the front row before the attack, and in less than ten minutes, the orc army has already come to the bottom of the city wall, you can imagine how fast these orcs run.

"Yaaaa aaagh！！ "When the first ladder was set up on the wall, the orcs' goblin trebuchets were finally launched, some carrying bulk explosives, some with weapons, carrying gliders on their backs to support the orcs who were about to kick the wall, but while they were still looking for a place to attack, the dwarves' helicopters had already aimed their machine guns at them.

The dwarven technologically successful helicopter (ordinary, combat helicopter) is only the size of a trolley, surrounded by four rotors, steam-powered, in addition to the remote control stick in the front cockpit of the aircraft is a rotating machine gun that is not very powerful (low-profile version of the organ cannon, the advantage is that the rate of fire is fast, the reload is more, twenty rounds at a time, the disadvantage is that it does not break the armor, the range is low, the accuracy is not good, and sometimes the pistol in the pilot's arms is not powerful, and it is only suitable for attacking enemies without armor or with a low armor rate. ）

"Bump Bump Tu Tu!" Hundreds of combat helicopters took off directly from the houses around the city walls, four rotors plus steam power, how is it not comparable to this group of shells that attack by gliding, although this suicide attack is extremely accurate, but it can't fall down no matter how high it is, hundreds of helicopters surrounded the city in the air on the inside of the city wall, and kept firing at the flying goblin shells, a helicopter is very expensive, not much less than a steam tank, the reason is in addition to the rotors, In addition, if each dwarf wants to ensure the amount of ammunition, he must carry a storage item so that he can change the ammunition at any time, after all, the space is so large, unlike the steam tank, which can hold a lot of shells.

However, these goblin shells in the air, the consumption is not much, sometimes lucky, a bullet hits the gunpowder on their body, immediately becomes a fireball, bad luck, the bullet has not completely killed the other party, before the bullet is reloaded, the dwarf pilot can only rush up to give a hammer, so although these goblins are temporarily isolated outside the city, but the battle in the air is still chaotic.

"The orcs have landed on the wall! Open the city wall protection!! Fire Dragon Gunner Ready!! "As more and more orcs approached, ladders were set up in the depression of the city wall, and many orcs wanted to climb up directly, but found that the city wall was not built of stone at all, but on the smooth side, except for the flame cannon in the middle of the city wall, there was no support point at all, so they had no choice but to wait in line to go up the ladder.

The dwarves of the city wall immediately stopped their actions after hearing the order, and the last row of thundering gunners immediately jumped to the lower city wall, and saw that everyone had left their places, and the dwarves in the turret position smashed a connecting rod hidden in the turret with a hammer, only to see a row of city wall tiles close to the outside with the sound of mechanical rotation "Click!" A sound rose from the ground of the city wall like a trebuchet, "Smack! The sound of the city wall stuck on the protruding surface of the wall, and immediately raised the wall several meters higher, and at the same time threw out countless explosive bags filled with broken iron and stones.

The all-metal shield that was turned up from the ground of the city wall not only increased the thickness of the city wall, but also added an additional slope of about a meter to the inside of the city wall to block the damage of the enemy's arrows, so the explosive bag that was thrown out before was not stuck far, that is, at the foot of the orc's ladder. In addition to the slope that blocks the enemy's long-range attack, the recess of the city wall is also blocked from above, leaving only the position of a dwarf, although the orc can still climb up, but he will never be able to climb into this hole, if you want to enter the city, sorry, continue to climb up.

The dwarves quickly laid out the missing ground, and the ranged troops on the walls descended two or so rows, replaced by ordinary dwarven warriors and dragon gunners with dragon cannons. As long as there is a ladder to hold the position of the city wall, the thundering gunner is very cooperative to give up the position, the fire dragon gunner holds the metal plate stuck on the city wall with one hand, and the fire dragon cannon with one hand directly adjusts the range to the farthest with one hand stretched out, and pressed the trigger along the ladder, only to see a fire dragon roaring out, and the orcs who climbed half of it were instantly engulfed by the fire, and some orcs saw that the explosive package that had just been thrown out did not explode, and they thought about climbing up the ladder and sending it back, but when they were not proud of their cleverness, they only listened to "Bang!" With a bang, the explosives exploded, and the iron pieces and stones inside immediately became a big killer, and the surrounding five-meter range was immediately emptied, but it was immediately filled again, but at this moment the ladder had also been burned, so I could only stand stupidly and wait for the ladder to come in.

The Dragongunner immediately retreats after firing, and the Thundering Gunner immediately fills up and continues to fire until another ladder is up and then continues to call out to the Dragongunner.

Because the city wall has increased, blocking the sight of many iron dragon gunners in the inner towers of the city wall, there has been a vacuum period for the hunting of giant beasts, taking this opportunity Many giant spiders climbed directly on the city wall, but the dwarves who had been prepared for it in the next second immediately drove them down, and the dwarf sulfur helicopter, because the sky was very chaotic, so after using some small means, Zhang Hao, who had been observing the dwarf defense battle system, did not notice the arrival of these planes slightly larger than the combat helicopter before the sulfur machine fired.

Heavily armored sulfur helicopters, the flight altitude is lower than that of combat helicopters, and the speed is much slower, this is because the proportion of metal in their bodies has exceeded 80%, it can be said that this is a big iron bump, which can spray high-temperature molten armor and sulfur, and has a strong armor-piercing ability. There are flame cannons in the middle of the city wall, iron dragon cannons on the city wall, and sulfur machines in the sky, plus the turrets that can't be hooked and armor-piercing bullets flying from time to time, these giant beasts are really fed up, and some giant beasts can no longer withstand this fierce defense, throw down their weapons and turn around and run, causing great confusion and accidental injuries in an instant.

"What about the number of goblin shells?!" Half an hour after the battle, Bernos leisurely returned to the front line.

"Back to my lord, the number of goblin cannonballs has been reduced by half, and not a single goblin has entered the city so far." The dwarf who replied proudly said.

"Has Prince Li made any moves?" Bernos asked, taking out his eagle eyes as he surveyed the battlefield.

"Is His Royal Highness Prince Li in the city?"

"Perhaps, have the goblin launchers been spotted?" Bernos turned around and didn't see Zhang Hao's figure.

"Yes, my lord, there are seven directions of goblin shells with the most concentration. There are hundreds of goblins flying every time, but today's wind is relatively strong, so many goblins can't fly before they land, otherwise there may be some chaos in the city now. ”

After hearing this, Bernos stretched out his hand into the air and felt it, there was wind, but the wind that could blow the goblin cannonballs away should not be enough. "Maybe a god is helping us, in that case, go tell the Sky Hammer and all the bombers to get ready to go."
