Due to the proximity to the magma, Su Chen even felt a slight tingling in his skin.

"Did Lothar really lead the human army to fight the orcs in the Blackstone Tower?" Su Chen couldn't help but have some doubts about this in his heart.

The black stone tower was built on the magma of this crater, and it was in high temperatures all year round, and ordinary people couldn't get close to it at all, even if it was orcs, not all tribes could tolerate the heat.

Moreover, Su Chen really couldn't see anything worth fighting for in such a magma-filled place, not to mention that even those dwarves knew that under this blackstone mountain was the lair of the Flame King Ragnaros, and humans and orcs should also know that staying on this blackstone mountain was equivalent to facing the wrath of the Flame King at any time.

A large part of the reason why the Black Dragon Legion chose to establish the Black Wing Lair in Blackstone Mountain today is that no other powerful force can afford it.

"There may be other reasons for the battle of the Blackstone Tower back then...... Su Chen thought secretly in his heart, but he soon saw a large number of Blackstone Orcs above his head rushing from the Blackstone Tower to the Blackstone Abyss along the huge iron chain, obviously these orcs coming down from the Blackstone Tower were indeed far inferior to Onexia.

After these orcs entrenched in the Black Stone Tower were absorbed by the Black Dragon Legion, they had already become slaves and cannon fodder of the Black Dragon Legion.

However, after receiving the weapons and equipment provided by the Black Dragon Legion, the combat effectiveness of these Black Stone Orcs has also increased a lot.

Such a huge movement had naturally alarmed the Black Iron Dwarves, and immediately many Dwarves had rushed out of the Black Stone Abyss below.

Fortunately, the place where Su Chen and Onexia were located was relatively hidden, so they were not discovered by those black iron dwarves.

It was the first time Su Chen had seen the black iron dwarves, these swarthy dwarves looked very brave, they had no fear in the face of those tall orcs, and even dared to rush to the iron chain that lay across the magma to face those orcs head-on.

The battle broke out directly on the huge chain!

The roars and roars of both sides resounded throughout the interior of the Black Rock Mountain, and in the screeching sound of the staggered weapons, people continued to scream and fall from the chains, including orcs and black iron dwarves.

"These dwarves just rushed out to fight?" Onexia, who had already transformed into a human, was also a little surprised by this, apparently she did not expect the Black Iron Dwarf to dare to rush into the chain.

However, the combat effectiveness of those dwarves is still not as good as that of the black stone orcs after all, or these dwarves who rushed out are probably not the elite of the black iron dwarves, and they were soon gradually suppressed by the orcs, and more and more orcs began to roar and rush through the iron chains, stepping on the scorching rock.

"Let's go in first." Onexia smiled at Su Chen as she spoke, and then her figure disappeared in front of Su Chen.

"It's ...... Incognito? As soon as Su Chen showed his shocked face, Zhi Brain had already provided a true vision through the detection of energy fluctuations...... Onexia was still standing in front of him.

"yes, aren't you also incognito, let's go in quietly." Onexia's voice whispered beside her.

"Aren't you going to fight?" Su Chen couldn't help but be a little speechless about this, but he quickly turned on his stealth ability.

"What am I going to do in battle, if I rush to the front and spend money to raise these orcs, let them fight with those dwarves, we will follow and watch, and by the way find the treasure troves of those dwarves, it is said that those dwarves are experts in treasure hunting, and they are also masters of treasure hunting." Onexia also seemed to know Su Chen's position after sneaking, so she grabbed him casually, and then dragged him into a cave.

Being held by Onexia so closely, although Su Chen had some strange feelings in his heart, he didn't resist, and it was also a very pleasant thing to go shopping with such a beautiful dragon woman, of course...... This time, we visited the Black Stone Abyss, which is deep underground!

As Onexia walked through the cave for a while, it dawned on him.

The Blackstone Abyss is huge!

This was Su Chen's first impression of this.

This is supposed to be a naturally formed volcanic cavern, so empty and tall that it can even allow Onexia to fly underground in the form of a black dragon, and only some of it has been processed by the black iron dwarves.

"Well, isn't this place beautiful, and I'm going to make it my new home in the future." Onexia said with some smugness, ignoring the fact that the blackstone orcs behind him were still desperately fighting the dwarves.

Su Chen nodded slightly, although he was still on the periphery of the Black Stone Abyss, he had to admit that this place was far better than Onexia's lair in the Dust Swamp, but he had to occupy this Black Stone Abyss first......

The resistance of the Black Iron Dwarves is very tenacious, and the troops that have rushed out have become more and more combative, and there are even a large number of musketeers, constantly using the terrain to stop those orcs.

However, the blackstone orcs look extremely crazy, they can't help but be well-equipped, and there are a large number of orc mages and shamans in the team, and even a lot of ogres and trolls, and their comprehensive combat power is quite strong, even if they are resisted by the black iron dwarves, they are still marching forward step by step.

Su Chen couldn't help but be a little surprised by the strength of these Blackstone Orcs, these Orcs entrenched in Blackstone Mountain looked even more powerful than those Orcs under Sal!

At this moment, he suddenly felt a slight tremor in the soles of his feet, and the next moment he saw a tall red monster rushing out from the depths of the ground...... That's a huge fire elemental!

This huge fire elemental looked very angry, and as soon as it appeared on the battlefield, it continued to release all kinds of fire magic to those orcs, causing great damage.

"This is the army under Ragnaros, it is very combative, and it is composed of fire and magma, and it is not afraid of siege, and it took us a lot of effort to catch a few of them before and go back to study." Onexia whispered, but it still sounded a little smug.

Zhi Brain was already rapidly analyzing the combat power of this fire element, and Su Chen was also thinking carefully about how to deal with this elemental monster that was covered in flames.

Ordinary soldiers must not be able to fight this fire element at all, and they can't even get close, even if the paladins have the blessing of the power of holy light, they can resist the scorching temperature, but if they want to attack it, they will definitely not be able to attack it, ordinary weapons are estimated to have melted as soon as they come into contact with this fire element!

Su Chen had to secretly sigh at the weakness of the human race, and if he wanted to effectively deal with this fire element, it seemed that the best way was for the mages to carry out long-range attacks, while the paladins had to get some equipment with flame resistance. (To be continued.) )
