Under a certain pillar of heaven on the second level of the dungeon, there is an unusually majestic city.

The city is actually not big, it is only more than 20 kilometers in circumference, and the reason why it is majestic is because the walls of the city are actually cast out of black cast iron, 50 meters high and 12 meters wide, God knows how many materials are used!

Even in the underground world, iron ore is the most important thing, but smelting iron ore into steel also requires a lot of manpower and material resources, so most of the underground world lords can only use stone to build city walls.

And the lord who is rich enough to build such a majestic wall with steel cannot be said to be none, but there are absolutely few pitiful.

It is also worth mentioning that the city is not only amazing in terms of walls, but also in the moat, because in the moat more than 100 meters wide outside the city walls, it is not clear river water, but red magma, which flows slowly and bubbles from time to time.

From the top down, the whole city is roughly divided into two parts, left and right, on the left is a huge magma lake, and the magma in the moat flows out of the magma lake and finally into the magma lake.

As for the right side of the city, it is a normal city, that is, the houses are taller, usually thirty or fifty meters high, and the inhabitants inside, except for the dwarves who are slaves, are mainly humanoids with giant blood, red giants and yellow giants.

The red giant is actually a giant of the fire attribute, the skin is red, as if it can burn at any time, their height is generally about ten meters, in addition to the rough skin and thick flesh, the strength is infinite, but also can spew flames from the mouth, directly covering the range of tens or hundreds of meters, very terrifying.

The yellow giant is actually an earth-attribute giant, and the surface of his skin is like dry earth, born with a crack, as if it can crack at any time.

They are slightly lower in height than the Red Giant, but they are a thick circle, like a Humpty Dumpty, and their strength and defense are more than a step above the Red Giant.

In addition, the Yellow Giant is also a natural earth summoner, and can summon earth elements to fight side by side with him anytime and anywhere, usually 8 to 10 at a time.

Although the combat effectiveness of these younger brothers is that they are black iron or bronze, they can contain the enemy, and they can summon them continuously, and they are not afraid of loss at all, which is equivalent to an extra cannon fodder army.

The most important thing is that after the Yellow Giant is injured, he can even recover his injuries by devouring the earth element, which is equivalent to an extra blood bottle that can never be used up.

So in general, the combat power of the Yellow Giant far exceeds that of the Red Giant, but the number is relatively small, and together they constitute the main class of the Lava Giant Lord Rockburst.

It is also worth mentioning that both the Yellow Giant and the Red Giant are capable of appearing Shamans, who are able to unleash shamanic spells that are suitable for the main element, and they are extremely powerful.

Of course, the price to be paid is to halve the power of the shamanic spells of other disciplines.

But despite this, the strength of these two giants is also very fierce, and the young man is at the level of the bronze upper position, and with a little serious cultivation, he can reach the silver level in adulthood.

They can even further purify their bloodlines and become even more powerful beings.

With these two giant classes, as well as two or three hundred thousand dwarven slaves, the city itself has a lot of combat power, plus the steel walls and the magma moat, it is simply impregnable.

Anyway, the city has not been harassed since it was founded, and it's not that no one wants to attack it, but after coming here to see the walls and moats, the other party basically gave up, and they didn't have the courage to attack this place at all.

The long period of peace has naturally made the people here unusually loose, because they do not believe that anyone would dare to offend this great and impregnable city.

Until this day, disaster struck suddenly.

I saw that in the originally peaceful city, there were suddenly more than 20 explosions, all of which were in the direction of the city, and each explosion completely destroyed everything on the surface, and at the same time exposed a huge hole twenty or thirty meters square.

Then, before the smoke from the explosion dissipated, powerful troops began to gush out of the hole.

In some places there were orc wolf cavalrymen, who shimmered with the brilliance of magic all over their bodies, wearing exquisite battle armor, but holding alchemical guns in their hands, riding on the back of the war wolf, screaming while spilling a series of bullets on all enemies in sight.

The dwarven slaves on the street were taken by surprise on the spot, either by bullets and with no skin, or simply trampled to death by the wolf cavalry.

In addition to the wolf cavalry, you can also see a variety of other cavalry units, such as the lizardman archer unit riding a lizard, the minotaur warrior riding an earth-walking dragon, and of course, the human warrior riding a demonized war horse.

In short, there are various types of cavalry, to say the least, there are more than a dozen.

But these cavalry also have one thing in common, that is, they have all given up the melee weapons they are good at using, and instead hold alchemy guns and keep strafing.

Moreover, when they were marching, they would throw two grenades from time to time, and the small group of defenders who had finally gathered together would be blown up directly, which was unbearable.

In the face of such a fully armed and modern army, the Red Giant basically has little room to play.

Even if they spewed out a breath of fire, they couldn't blow away all the magical protection on the cavalry, at most they just blew a hot air on others.

But the next counterattack is not something that the red giant can withstand.

Maybe the red giant can resist the direct fire of small-caliber machine gun bullets, but when people take out bazookas, these big guys can only kneel on the spot, and those who are lucky not to die don't dare to fight anymore, and directly hug their heads and run away.

The 107 bazooka, that is definitely a big killer, especially after being equipped with frost that specializes in restraining the red giant, and after the rocket launcher, it is even more tragic for the red giant.

On the street, but the red giants who still dare to jump out will be immediately targeted by several bazookas, such a close distance, such a big target, I'm afraid it is impossible for a blind person to hit crookedly!

If it was only two or three frost rocket launchers, the red giant could still carry it, even if it was an ice spell that specifically restrained them, it would at most beat them to frost, and they would directly change from a red giant to a white giant.

Of course, the cold frost mana would invade the Red Giant's body, draining the power of his flames, making his body stiff and brittle, making him extremely vulnerable to injury.

In this case, the Red Giant's combat strength is not ten percent left, and he can't even spray flames, so how can he fight against a large group of knights like wolves and tigers?

They are lucky enough to be able to escape, and the Red Giants who can't escape are usually broken on the spot.

As for the Yellow Giant, it's much better, these guys' defensive capabilities are at least two grades higher than the Red Giant, especially when they can recruit a bunch of cannon fodder anytime and anywhere, the little brother is in front, even if it is rocket artillery, they can't hit him, they are all blocked by the earth element he summons.

However, Princess Claire came prepared after all, and they had already inquired about the advantages and disadvantages of the two giants in advance, and they must have prepared measures to deal with them.

I saw a yellow giant on the street rushing up with his little brother in a menacing manner, but before they could make a move, two or three rocket launchers came over at the other side.

Accompanied by a dull explosion, gray-white magical light filled the area within a radius of several tens of meters, and all the earth elements were illuminated by this magical light, crumbling and disappearing without a trace.

This is a spell invented specifically for summoned creatures, the exorcism, which actually did not kill them, but only sent them back to their original earth elemental plane.

And without these cannon fodder in the way, there is only one yellow giant left, and it is not a threat at all.

First of all, use ice spells to slow down, so that the Yellow Giant's already inferior movement power becomes lower, and then there are grenades, rocket artillery, no matter how tired you are, you will definitely not be able to bear it.

In this case, the whole city was thrown into chaos in an instant, and a large number of knights scurried back and forth through the streets of the city, frenzied slaughterers, and all the citizens they met.

And several of the most powerful knight troops have a purposeful attack on the most important points of the city, one is the city lord's mansion, and the other is the military camp station.

Only these two places, there are also formed giants and dwarven warriors, capable of fighting the invaders.

As for the stragglers in other places, they were basically strangled by the cavalry troops.

Unless it is a super master above gold, otherwise, against the army with firearms alone, it is basically a kneeling, and it is luck to escape!

Soon, the battle of the city lord's mansion and the two military camps began.

Needless to say, the city lord's mansion itself has a very strong defense, plus there are the most elite giant troops inside, which is not at all something that one or two thousand cavalry can solve.

The cavalry troops, who originally wanted to pick up cheap, opened the gate of the city lord's mansion with rocket artillery, and rushed in excitedly, and the powerful firearms gave them the confidence that they could do anything.

But unfortunately, this kind of self-confidence is not the real strength, after entering the City Lord's Mansion, they will soon be besieged by the ambushed giants, and the flames of the fire giants keep spewing down, layered on top of each other, and no amount of protective magic can be carried.

The most annoying thing is the yellow giant, who directly summons the earth element to the middle of the knights, so that the knights don't dare to use rocket artillery at will, for fear of accidentally injuring their own people.

But the enemy didn't care about the life and death of the earth elemental, so the red giant continued to fire, and the yellow giant kept throwing all kinds of weapons or simply furniture, and directly wiped out all the cavalry that rushed in.

In the same way, the cavalry attacking the barracks also suffered heavy losses, and although they took advantage of it outside, as soon as they attacked it, they would be surrounded and annihilated.
