After receiving the order, the flying legion in the north and south, which had been engaged in the battle with the Warcraft army, and had been assembled in the air because of the withdrawal of the Warcraft, immediately climbed rapidly as a whole, and raised the height by ten meters.

Originally, they had organized their aerial defenses almost parallel to the height of the city walls and fought against the Warcraft army, but now they had increased their height and were already above the Ultimate Mobile City Arrow Tower.

"Eighty meters back," Dragonthirsty ordered again.

The defensive line of the entire ground legion is based on the 80 meters outside the city wall as the defensive camp, because in order to achieve the three-dimensional structure of the air and the ground as an integral defense, the defense circle in the air is naturally 80 meters outward from the arrow tower as the defense range.

Retreating 80 meters now is equivalent to retreating to the sky above the city.

"Prepare for shelling!"

With the dragon's bloodthirsty command again, the holes of the dense arrow towers stretched out a series of black hole cannon muzzles.

Buy NPC Archer? Murong Xiao didn't think about it at all.

That's going to cost a lot of RMB, not to mention, to open the process of buying NPC archers, and to do task drops, Murong Xiaotian has never done it at all, and he doesn't plan to do it.

It's not worth spending money on these low-IQ junk NPC archers.

As an increase in the defense power on the Ultimate Guild's Arrow Tower, he certainly has more powerful weapons, so how could he choose those NPC archers?

Don't forget, the Baksa family's technology in making magic cannons, how could Murong Xiaotian pay him Lang?

When I was on Fengkou Island, I had a battle with this warrior West Asia, and the two of them grabbed half of the manufacturing technology of the Baksa family.

What the warrior Xia got was the shipbuilding technology, while what Murong Xiaotian grabbed was the manufacturing technology of the magic cannon.

After such a long time, do you think Murong Xiaotian will use this magic cannon technique as an ornament? It has been handed over to the builders gathered in the gourd bend for a long time, and the manufacture of magic cannons has begun.

Today's mobile cities in the air have this magic cannon installed in every arrow tower, as well as enough fuel ore.

In the battle of Fengkou Island, facing the warrior West Asia, the three players, the two wild heroes, plus the combined armor pet that Murong Xiaotian saw for the first time.

Although he snatched the artillery-making technology from the hands of the warrior Xia Xia, Murong Xiaotian had to evacuate quickly.

No matter how many members there are, a few heroes, or a few pets, it is a fact that it is you Murong Xiaotian who finally escaped.

Hehe, grandma's, today I will use what I snatched from your warrior Xia to let you taste its power, and it can be regarded as revenge for this arrow.

The attack distance of the magic cannon can reach up to 500 meters, and when the air legions of the 'United Guild of the Great American Alliance' and the 'United Guild of the European Union' flew to a distance of three hundred meters, the Dragonthirsty gave the order to attack.

Within the perforations of the arrow towers on the north and south sides, a stream of fire burst out, covering the arc of the projectile.

"Crackling", exploding in the air legions of the two major alliances.

"Damn it, bastard, order the troops, quickly take to the air!" The warrior Sia roared.

This fierce artillery fire reminded him of the scene on Fengkou Island.

TMD, it's this damn cannon-making technology, my three masters, plus two heroes, an eighth-level pet, and let me be a thief and that bastard snatched this cannon-making technology from his hands.

Not only that, but in the end, you can get out of it all right!

Without this artillery-making technology, I wouldn't have been able to dominate the entire Destiny Sea with a thief's sea fleet.

Now, the siege of the city still has to withstand this heavy shelling.

Think about it, the warrior Sia is a fire in his belly.

The super jazz of the 'EU Joint Guild' is not a pig, and it is also the same that allows the air team to quickly rise to height.

The well-trained artillerymen in the arrow tower fired a magic cannon every two or three seconds, and there was an arrow tower at a distance of two meters.

Countless players have hung back the 'temporary resurrection point'.

By the time they reached the height beyond what the magic cannon could throw, the entire formation was already overwhelmed.

There is no way, it can only regroup the air power, raise the altitude in the air, and cross the projectile height range of the magic cannon to attack the city.

"Adjust the muzzle of the gun, aim it at the ground, the distance, within 100 meters to 300 meters, cover the whole process," and when the ground forces of the two alliances still had twenty meters to rush to the defensive position on the ground, the dragon bloodthirsty spoke again.

The blow of the magic cannon to the enemy's air legion can only be a one-time one, and the second time it will not work, and the other party will suffer a loss, how can it repeat the mistakes of the past?

Raise your flight altitude and fly over your Arrow Tower to attack your guild castle as well.

But in this way, the magic cannon can carry out fierce attacks on the ground enemies without hindrance.

Because the opponent's air legion has raised the height to a height that is more than a few dozen meters higher than the arrow tower, then, if the air power on his side is quickly blocked, there will naturally be no matter if the magic cannon accidentally injures his own people.

There was no need for the dragon's bloodthirsty mouth to speak, the long sky without wind in charge of the north, and the celebrity Absolute Wind in charge of the south had already commanded the air team that had retreated earlier and quickly met it.

In an instant, there was another exchange of fire in the air, although the aerial battlefield was raised to a height of nearly 100 meters from the ground, within a range of 80 meters from the castle of the 'First Thief Guild in the World', it was still firmly controlled by the air legion of the 'First Thief in the World', and the three-dimensional defensive structure was still effective.

This prevented the enemy from suddenly descending and carrying out an air-to-ground strike on the ground defense forces of the 'first thief in the world'.

"Boom, boom, boom......"

The ground legions of the two alliances, under the heavy artillery attack, let alone breaking through the defense line of the 'No. 1 Thief Guild in the World', can't even do a decent attack.

You think, the forward position of the 'First Thief Guild in the World' is at a distance of eighty meters, and the range covered by the magic cannon is between 100 and three hundred meters.

By the time you rush to the front, how many mages with fragile health will be left?

Although, there is the protection of the nurse who is responsible for adding blood.

It's not nice to say, a really awesome summoner, the one who doesn't have a flying pet? It is estimated that they have already joined the ranks of the air team.

And the summoners in the ground forces are estimated to be the weaker summoners in the entire force.

In the face of such a fierce magic cannon attack, they are afraid that they will not be able to protect themselves, right?

And when those warrior knights rushed to the front, they had to face the oncoming warriors, and they had to be careful of the fierce stabbing of the knights' spears behind the warriors.

At the same time, there are also patches of various magical attacks flying down overhead, how can you fight this battle?
