I have to say that in the face of a group of powerful teams who are determined to come to 'slay the dragon', the black iron dwarves in front of them are really not enough.

Perhaps in this Burning Plains, they can occupy a lot of territory with their indestructible black iron towers and *weapons, and become one of the right-hand men of the Tier 2 Fire Dragon. But once they encountered Grim and the others, the fate of the Black Iron Dwarves came to an end!

Without even Grim's own intervention, Mary took Winliel and Soros into vampire bats and slipped through the firing port of the Black Iron Tower, followed by a brutal and wanton slaughter.

Knowing the fighting methods of the Black Iron Dwarves, the three vampires naturally would not give them any more chances. Either kill them instantly as soon as they meet, or quickly escape from the blast zone when they find out that the other person is ignited*......

Grim stood in front of the Black Iron Tower, and heard only the desperate and painful cries and roars of the Black Iron Dwarves inside. From the bottom floor, there are sporadic explosions. Looking at the thick tongue of fire spewed out from the lookout and the shooting port, listening to the crisp sound of the musket like popping beans inside, the bloody slaughter extended from the bottom of the tower all the way to the top, and the weak black iron dwarf finally despaired and collapsed in the face of three terrifying killers who were like ghosts......

The door to the Black Iron Tower was opened again, but this time by the Goblin Ripper!

It can be seen that the gray face of making trouble in front of a group of weak chickens just now also made Tigul a little embarrassed, so he also had the intention to kill on a large scale to wash away the previous humiliation.

Unfortunately, when the tower gate was opened, no black iron dwarves escaped inside. The entire hall on the first floor was filled with strangely shaped corpses, and of course, the corpses of dwarves that had been blown beyond recognition.

On the stone spiral staircase on one side of the hall, corpses lay upside down, all of them still clutching the smoke of broken muskets. And the pungent black blood flowed down the stone staircase, and it had gathered into a black lake in the corner of the hall.

The Black Iron Tower was built quite high, and due to the rapid killing of the vampires, the battlefield had extended to the upper floors of the tower, so the continuous crisp sound of popping beans could no longer be heard in the hall on the first floor. However, the power of the black iron * is still not small, and the entire black iron tower is still trembling constantly, and the dust and iron powder above the head are falling, making this place also full of a strange atmosphere of fierce and dangerous battles.

The high-level Black Iron Dwarves have also tried to blow up the spiral stone ladder with * to block the enemy's attack, but unfortunately this trick may work against ordinary enemies, but it would be a bit self-digging to use it against wizards.

If you can't walk the stone stairs, then go outside the tower!

The vampires rushed out of the tower, then flew to the upper floor, and then rushed in through the ubiquitous lookouts and shooting ports. This time, the black iron dwarf even blocked his only way to escape, and he could only be killed. Many of the Black Iron Dwarves were forced to roar and ignite the * bound to their bodies, and then burst into despair as the other party quickly moved away.

You can't beat it, you can't blow it up!

The remaining Black Iron Dwarves were in utter despair, and before the vampires could kill them, they jumped off the tower one by one. With their small size, they have no ability to fly, no deceleration mechanism, and can only snap around the tower and fall into a mass of meat sauce.

Finally, twenty minutes later, the steel tower, which was three hundred meters high and had more than 400 black iron dwarves, was completely silent.

A quick search of the entire tower revealed rows of neatly stacked iron ingots, steel ingots, and other special metals in the Black Iron Dwarves' supply warehouse. Among them, rare resources such as mythril, pure gold, dirt copper, and magic iron are naturally indispensable, as well as some valuable magic gems.

The Black Iron Dwarves hoarded these things, naturally to pay tribute to the Fire Dragon Lord, but now they are all cheaper than Grim and the others. Seeing this, all the members of the dragon slaying team appropriately collected some gems and resources that they could, and the rest were all packed up and taken away by Grim.

As for the huge amount of ordinary metal, it can only be thrown in place.

Although Grim had also resealed the storehouse and imposed a simple seal, it was impossible to waste such a high-quality dwelling in the wilderness. As soon as they left, the place would be occupied by other natives who had heard the news.

At that time, it will also become a lair of the new regional hegemon.

Therefore, no amount of seals can be put in vain!

…………

After passing through the Black Iron Tower, it is the territory of the Firethroat Dragonmen.

In this red, scorched land, there is no space and environment for foreigners to live and reproduce.

Walking on the fiery red and hot rock slabs, the leather boots under your feet will make a strange sound of frying the skin and meat as soon as they touch the ground. As a last resort, all wizards can only release some elemental particles to protect the leather boots under their feet, otherwise they will not be able to walk half a mile, and they will only be able to walk barefoot.

The arrival of Grim and his party has obviously alarmed the fire-throated dragons here.

In the distance, the humble camp roared and roared, and groups of fire-throated dragonmen gathered and were desperately advancing in the direction of the Black Iron Tower.

Truth be told, as soon as Grim and his party stepped into the Burning Plains, the leader of the Firethroat Dragonmen had already gotten the news.

It's just that at that time, this group of aliens was only operating on the periphery of the Burning Plains, and did not show any intention of invading. Therefore, the leader of the fire throat only drank to ask the peripheral vassal forces to pay attention to the movements of this group of aliens, but he did not really get nervous.

After all, Lance belongs to the private plane of pure-blooded dragons, and the possibility of war between dragon lords is very low. Even if two dragons fight each other, it will only be their vassal dragonmen or indigenous forces who will fight back and forth, and the bad incident of directly going into battle and directly smashing the lair of the opposing dragon lord will almost never happen.

Therefore, the leader of the fire throat just ordered his subordinates to maintain general vigilance, which is already a sign of extreme vigilance!

It's a pity that it can't be calculated even if it is calculated, and this group of outsiders will be so decisive and so fast.

Almost the day before yesterday, I received news that a group of outsiders had broken into the Burning Plains, and the next day they found that they had crossed the Angolo volcano and their whereabouts were unknown. By the time the leader of the Throat suddenly became alert and looked around to find out the whereabouts of the group of outsiders, the direction of the Black Iron Tower in the distance had already lit up with thick smoke calling for help.

At this moment, the leader of the fire throat, who was originally at peace, could no longer sit still!

While sending people to the fire dragon's lair to warn, it frantically summoned the dragonmen scattered around it, gathered a team and rushed to the Black Iron Tower.

Unfortunately, it is still a step slower!

I'm afraid no one would have imagined that it would take less than twenty minutes for this group of outsiders to wipe out the entire Black Iron Dwarf, and then leisurely cross the Black Iron Tower, bypass the Fire Throat Camp, and approach the Fire Dragon's Lair step by step.

Therefore, when the leader of the Throat of Fire hurried to the Black Iron Tower, all he saw was a dead place full of dwarven corpses, and the enemy was long gone.

If you were an ordinary fool, you'd have to scatter your men and search for traces of the enemy near the tower. However, this fire throat leader was very experienced, and when he saw this situation, his heart sank, and he immediately led people to run wildly in the direction of the fire dragon's lair without hesitation.

It is 120 miles from the Throat Camp to the Black Iron Tower, and another 170 miles from the Black Iron Tower to the Dragon's Lair. Even with the strong physique of the Fire-throated Dragonman, running nearly 300 miles in one breath, it is still a rhythm that makes people vomit blood!

However, while the Firethroat Dragons were running wildly across the scorched land, Grim and his party had already arrived at the Dragon's Lair and joined up with the Blood Knight who had been crouching there.

…………

In the middle of the burning plain, there is a narrow fissure zone that stretches for more than ten miles.

Standing on the edge of the rift valley and looking down, you can see the dark river of magma rushing and surging thousands of meters below. The steaming heat wave and the strong pungent smell of sulfur make this place a forbidden place for life.

Anyone who gets too close to the Rift, even if they don't get roasted by the heat, will be killed by the harsh air here.

"My lord, I've been waiting here for twenty days, and I've never seen that fire dragon come out......," the Blood Knight, who was in charge of guarding the place, reported respectfully to Grim with his hand on his chest.

It can be seen that he has suffered a lot here these days.

Not only were the clothes on his body softened by the red of baking, but even his body was covered with scorched black burns.

Being able to leave such a visible scar on a Tier 2 Blood Knight also fully illustrates the harshness of the environment here and the scarcity of flesh and blood creatures. Although there are fire-throated dragons everywhere, in order to avoid startling the snakes, the blood knights do not dare to attack them.

"Well, I've already taken credit for your work, now I'll go back to the team first. Grim simply praised two words, and then turned back to the crowd: "The fire dragon's lair is below, let's go down!"

With that, Grim was the first to take the lead and jump out of the rift canyon.

Waves of scorching fire gushed up from below, but were blocked by the flame barrier around Grim's body.

Fire and fire collided, burning the flame barrier red, with a violent crackling sound.

Grim ignored this, and swept around the dark red rock walls on either side as he fell.

Finally, after descending less than 200 meters from the magma undercurrent, Grim scanned the rock wall on the north side of the rock wall to see a circular platform that protruded outward, on which the glow of magic runes could be faintly seen.

There it is!

As soon as Grim's gaze, whose body was still falling rapidly, the flame jump was already activated.

In the next second, there was a flash of fire on the circular platform, and Grim's tall body had quietly emerged.

The entrance to the dragon's lair has finally arrived!
