Black Rock City, this is a gray dwarf city in the underground world, the entire city is built by obsidian, the city wall up to more than ten meters has a huge defensive capacity, the obsidian itself magic resistance attributes, plus the rune magic attached by the gray dwarf on the city wall, it can be regarded as an impenetrable fortress.

The city walls alone could not stop the large number of players gathered outside the city, and what stopped everyone was the high-level dual-purpose rune rapid-fire gun on the city wall, the rune wizard tower standing behind the city wall, and the rune bombs and other runic weapons thrown by the gray dwarves defending the city.

Add to that the number of fourth-order rune mages who have not yet been fully detected, plus fourth-order dwarven priests who can regenerate health, rune warriors who can operate rune weapons, and rune craftsmen who can repair rune weapons.

With such a sturdy and huge fortress city, Blackstone City is naturally the core formation base of the Underground World Formation.

At this time, there were four groups of players gathered outside Black Rock City, the east and west were all players organized by the Grand Guild, although their respective numbers were not the largest among the four groups, but their strength was the strongest among the four groups of players, the east was the members of the True Dragon's Eye Society, and the west was the members of the Endless Dragon Palace.

Occupying the south side is a group of players united by several clubs; The north side is full of scattered players, although the number of scattered players is the largest among the four groups, but the strength is uneven, and although they are united, they are indeed the most disunited of several groups of players, and no one is convinced, dare to eat with the top club of the school, how can they listen to other players.

Now it's just a temporary union, and as for entering the city, they will naturally fight separately, and whether they can get the opportunity depends on their luck.

As for going against the big guild, anyway, in the game world, it won't really die, of course, if you don't accept it, you just do it, after all, people who have the guts to snatch food from the big guild, when facing the real interests of themselves, who will care who they are, and whether they can get the harvest is of course to know if they have been beaten.

And Long Zehao and Menglan also stood among the scattered players, as time passed, the lead of the two of them had gradually disappeared, and this time they encountered a large number of players who entered the underground world from another entrance.

With the appearance of the agreed attack signal, the four groups of players sent their respective troops together, among which the True Dragon's Eye and the Endless Dragon Palace were the most regular, and the heavy shield defense class, the long-range attack class, the auxiliary magic class and the flying class in the sky, under the command of the command system professional players, slowly pressed towards the Black Rock City.

Although the club alliance has a distinction between the troop occupations, the formation is much more scattered, but at least one formation exists.

And the scattered players can't look at it, the formation lined up before the battle, before entering the siege distance, they have already scattered first, and each directly commands their respective troops to fly forward quickly, but the scattered side is the first of the four players to enter the battle state.

It's not that the scattered players are brave, but the cannon fodder classes are used now, who uses defensive troops in the process of starting a war, who carries out assault missions, who uses ranged troops, etc. Before the war, there was no way to talk about it, so there was no way to simply use cannon fodder troops, ready to directly rely on the number of people to directly force in.

In fact, the best way is to use the battle contribution to settle, and finally everyone distributes the final harvest according to the battle contribution, but there are a large number of scattered players and each has its own small plan, and there are three other groups of organized players attacking the city, and they will not make any combat contributions with the scattered players.

Because there is no command, the scattered players have chosen the most direct method, which is to summon all the flying troops, and everyone will directly participate in it after the battle begins, and don't divide it into the main team, defense team, auxiliary team, reserve team or something.

Unlike the other groups that fought steadily, on the side of the casual players, when the war started, they saw countless flying classes flying towards the head of the Black Stone City Wall, including giant dragons, true dragons, dragon-blooded winged people, and ......other flying classes such as eye demons, flying monsters, flying cavalry, etc.

The first to attack was the defender of the city, Blackstone City, the entire body of the rune tower built behind the city wall lit up with bright light, and the spires of the black towers built of obsidian gathered powerful magic power, and then a series of magic rays directly attacked the player's troops.

The powerful city defense rune tower, each magic ray can penetrate nearly ten troops, of which the first two or three are directly killed, and then directly enter the residual blood state, and slowly reach the last half-blood state.

Although the power of the rune tower is great, fortunately, the attack speed is not very fast, and it will soon enter the range of long-range troops.

Compared to the rune tower, which has huge damage from a single target, the threat of the high-level rapid-fire rune gun on the wall is even greater for the player.

Because the number of rune rapid-fire guns is even larger, only one rune warrior can operate it, and more than a dozen magic ray attacks per second, only to see that the sky is full of traces left by magic ray attacks, intertwining the entire sky into a magic net of death.

Fortunately, the power of the rune rapid-fire gun is only relative to the skill attack of the same level of troops, although the power is large, but it is not comparable to the rune tower, if the magic ray of the rune tower is as thick as an arm, the magic ray shot by the rune rapid-fire gun is only the thickness of chopsticks, and the attack of the rune rapid-fire gun can neither second the player's troops, nor the ability to penetrate and attack other classes behind the attack.

Compared to the attack of the gray dwarf troops defending the city, the player's side is much more scattered, fireballs, lightning, wind blades, dragon breath, arrows, etc., and the long-range attacks that can appear have basically all appeared in the player's troops.

As the siege forces advanced, the defenders of Blackstone City behind the walls joined the siege forces, and endless ranged attacks appeared between the sky and the ground.

One by one, the flying units lost their lives on the way forward, falling from a height of more than ten meters, and on the road to Blackstone City, along the way were the soldiers of the player unit who were attacked and killed.

The gray dwarf troops, which were attacked by the player's miscellaneous units, also had a rune warrior who operated a rune rapid-fire gun lose his life from time to time, and just fell to the side of the weapon.

The walls that were attacked left traces of the Dao, a wall of venom on the left and a wall of fire on the right...... As long as you enter the attack range of these skills, you will take damage over time.

It's just that under the order of the hero defending the city, a rune warrior rushed out of the hidden army room on the city wall, and they quickly came to the side of the dead rune warrior, directly operated the rune rapid-fire gun crooked to the side, and re-launched the attack on the player troops approaching from afar.

There are also rune craftsmen who come to the side of the rune rapid-fire guns that have been attacked and damaged by the durability of the rune guns, and take out parts from the craftsmen's pockets one by one to repair those broken weapons.

Hidden inside the rune tower behind the city walls are dwarven priests and rune mages.

The rune warrior who fights before the Dwarven Priest releases a healing spell to heal him.

Some rune mages operate rune towers to perform mana ray attacks, while others release life-enhancing spells such as Dao Defense Enhancement, Mage Shield, Virtual Life, and Life Regeneration to the rune warriors who are fighting in front.
