Even though they were several kilometers away, the roar was so penetrating that it shook my heart, and everyone else was taken aback, because I had told them that Xu Yu and I had eliminated the three demon dragons lurking in the Yin Lake. But that roar just now was as good as the three demon dragons.

I immediately turned my head to Xu Yu and asked, "Senior Xu Yan, is there another three-headed demon dragon in this ghost place?" ”

But he didn't answer me, his piercing eyes staring in the direction of the fortress, as if thinking about something. At this time, the fire was still flickering, and I couldn't help but worry a little, because the fortress was still garrisoned by thousands of slaves, and I didn't know if the gas explosion would hurt them.

I was pondering in my heart, and I said as if to myself, "Could it be the Fire Demon?" ”

I hurriedly asked, "What fire demon?" ”

Xu Yu took a deep breath and said: "The Flame Demon is one of the ten major demonic beasts of hell, and there are raging flames burning all over the body, which is extremely difficult to deal with. ”

As soon as Xu Yu said this, Wen Qingshan on the side immediately took his words and said, "Could it be that this underground Yin Lake is the Yin Lake used to suppress the Flame Demon?" ”

Xu Yu nodded: "This Yin Lake is very hidden, and only a few Heavenly Gods know its location. The old man can't be sure, but if that thing is really a fire demon, then it means that it is this yin lake, and the fire demon may have broken through the seal. ”

When I heard this, my mind suddenly jumped to think of the secret project, where the slaves had not known why they had to dig a huge passage into the depths of the earth, and I had thought that the demons were trying to open a passage to hell. But now that you think about it, the owl monster and the human wolf beast originally came from hell, which means that the passage to hell has always existed, so they must have another purpose in digging this passage, and this purpose is likely to release the legendary fire demon!

Thinking of this, I immediately spoke: "You say, could the secret project carried out by the demon be to release the fire demon sealed in the depths of the earth? ”

My point of view was immediately agreed by the others, and Wen Qingshan hurriedly asked Xu Yan, "Senior Xu Yan, if it is really a fire demon, what is the way to deal with it?" ”

Su Yu said with a solemn expression: "If it is really a fire demon, even if the old man's strength is fully restored, I am afraid it will be difficult to subdue it, and when it completely breaks through the seal, this place will be completely reduced to purgatory." ”

Hearing Xu Yu say this, everyone was in an uproar, and Xu Yu changed his words, and said: "But a qiē is still just the old man's speculation, if you want to know what's going on, wait for the old man to investigate first." ”

As soon as I heard this, I immediately said, "I'll go with you!" ”

Xu Yu turned his head to look at me, thought for a moment, nodded and said, "You know how to resist fire, it's good to go with the old man." ”

As soon as his voice fell, he suddenly flew up, soared into the air, and quickly turned into a green dragon, seeing this, everyone was shocked and speechless. And I didn't expect Xu Yu to actually turn into a dragon in front of everyone, so I had to explain to everyone that Xu Yan's cultivation has entered the realm of transformation, and he knows the art of transformation, and he can transform into a dragon.

The green dragon circled in mid-air, slowly landed in front of me, and leaned down so that I could sit on its back.

I was about to ride up, but suddenly I thought of something, turned to Long Yi, Wen Qingshan and the others and said, "You guys take Professor Dong and them away first, and I'll go there with Senior Xu Yu to have a look!" ”

"But if it's really a fire demon, how can you two deal with it? Or let's go over together. "Wen Qingshan built yì road.

As soon as he finished speaking, Xu Yu said in a majestic voice: "Ordinary people are not able to resist the flame demon at all, if you go, not only will you not be able to help, I am afraid that you will also cause trouble." ”

"But ......" Wen Qingshan wanted to say something more, but I hurriedly interrupted him and said, "Boss Wen, don't worry, even if it is a fire demon, we will definitely be able to get out." If there are too many people going, the seniors will still be attentive to take care of it. Why don't you leave with the others first, and then make plans when we figure out what's going on. ”

The dragon on the side nodded: "Shi Yu is right, let's do it." He turned to the slave leaders who had sent us out and said, "You'd better be prepared to evacuate, for if it's as the Sudai seniors said, then the Flame Demon can turn this place into purgatory, and he won't be able to stay in this place anymore." ”

Several slave leaders listened to Long Yi's words, and their expressions were solemn, they were not willing to give up their homeland like this, but they could also see that they were afraid of the legendary fire demon.

Without further ado, as soon as the dragon led the group, he prepared to leave, fearing that they would encounter man-eating monitor lizards and giant rats in the intricate caverns, and might even encounter the remnants of demons who had fled inside, so I summoned Dustless and asked him to lead them away.

After the arrangements were made, the green dragon carried me and flew away in the direction of the fortress.

Although it was seven or eight miles away, the speed of the green dragon was extremely fast, and it didn't take long for us to fly to the top of the fortress, I glanced down and couldn't help but be surprised, at this time inside the fortress, in addition to the towering city gate, the canyon had already become a sea of fire, and many people gathered above the city gate, shouting in horror and despair.

Seeing this, I hurriedly said, "Senior Xu, go and help them!" ”

The green dragon let out a deafening groan, and after circling in mid-air, it swooped down and flew above the canyon, opened its big mouth, and exhaled a cloud of soft white aura towards the sea of fire.

The soft white aura instantly extinguished the flames in the canyon, the green dragon slowly fell from mid-air, and I came down from its back, and it also turned into a whisker.

I looked around, and the scene before me was simply shocking, and there were many charred corpses lying in the canyon, presumably slaves who had not had time to escape, burned alive. It is enough to see that this fire came quite urgently.

There was also a very pungent smell in the canyon, which smelled very similar to the smell of sulfur, which made me feel a little surprised, because if it was a natural gas explosion, it should be filled with the smell of natural gas, how could it be such a strong sulfur smell. I thought it was strange, but I didn't think much of it.

Because the smell was so bad, I hurriedly held my breath. However, Qinglong didn't seem to reject this smell, instead raised his nose and smelled it deliberately, and then said, "It seems that this evil fire is really related to the fire demon. ”

"Why?" I hurriedly asked.

"Because there's the smell of fire around here."

"The smell of the firefiend?" I was slightly stunned in my heart, and said secretly: Could it be that the smell of sulfur is the smell emitted by the fire demon?

Thinking of this, I couldn't help but be a little nervous, and hurriedly secretly urged the fire dragon qi in my body, but then I thought that since the fire demon is a fire demonic beast, I am afraid that using the fire dragon qi will not have any effect on it at all, and if I want to deal with it, I am afraid that I will have to rely on the dragon crystal sword qi in my body, but unfortunately now I can't urge this supreme divine sword at all.

I had to pull out the dragon tooth and hold it in my hand, in fact, against this level of demonic beast, the dragon tooth can't play any role at all, and I just want to feel at ease by holding the dragon tooth in my hand.

I was wondering what the Fire Demon would look like, and I said again, "However, judging from the scale of this fire, it may not be the Fire Demon. ”

"Didn't you just say that there was a smell of fire demons here, and now why do you say that it's not a fire demon?" I was a little dazed.

Su Yu explained: "That's right! This smell is indeed related to the Fire Demon, but it is not necessarily the Fire Demon, if it is really the Fire Demon breaking the seal, I am afraid it is enough to cause a volcanic eruption. ”

Hearing him say this, I couldn't help but be shocked: "Damn! Is this monster so powerful? ”

Xu Yu nodded: "The ten demons of hell, in addition to the god of hell - the nine demon dragons and the night demon, the fire demon is the most powerful, it is not an ordinary flame burning around it, but a hell demon fire that can burn all things in heaven and earth, if it is really a fire demon, I am afraid that the cold mist spewed out by the old man will not be so easy to extinguish the fire." ”

"If it wasn't for the Fire Demon, what would it be?"

"It's supposed to be a fire beast!"

"Flame beasts? What the hell? ”

"The flame beast is the minions of the fire demon, and there are also raging flames burning around it, since the fire demon was sealed, the fire beast has also disappeared with a piece, and it has not appeared in the world for thousands of years, so some people think that the fire beast is actually the companion of the fire demon."

"Is this flame beast easy to deal with?"

"The flame beast is not difficult to deal with, but ......" Before he could finish speaking, suddenly a deafening roar came from a cave next to the cliff wall of the canyon, and I hurriedly turned my head and followed the sound, only to see that there was a fire shining out of the cave, and the fire swayed back and forth, as if something that could move was burning.

I didn't dare to be careless, so I hurriedly put the dragon's teeth across my chest, but Xu Yu said, "Don't be nervous, it's just a fire demon, it can't hurt you, you can use the fire control technique to extinguish the flames around it." ”

Hearing this, I hurriedly recited the fire prevention trick silently. At this moment, a large burst of fire rushed out of the cave.

I fixed my eyes and couldn't help but be taken aback, in this burning flame, there was actually a hideous demonic beast, this demonic beast was huge, more than two meters tall, more than three meters long, and the flames burning around its body were fiery red, it stood there, and the rocks on the ground were even burned red, which showed that the temperature of the flames was not ordinarily high.
