"Who is talking?" Zhou Tianlong and the others were suddenly shocked, never dreaming that in such a terrifying place, there would be human beings.

"What should we do now?" Yu Feilin's palms were covered with sweat, holding Zhou Tianlong's hand tightly, and a pair of beautiful eyes were also staring at Zhou Tianlong's face. She is basically in chaos now, and Zhou Tianlong is her backbone at this moment.

I saw that Zhou Tianlong's face was extremely solemn, and after thinking for a long time, he said to Yu Feilin: "Let's go to the deepest part of this cave to see who is here!"

Yu Feilin just nodded mechanically, she has no idea at all now, and now that Zhou Tianlong decides, she will listen to what she will follow.

Zhou Tianlong had his own plans in his heart. He knew that even if the two of them could escape from this cave, they would never be able to leave this tunnel, and the result would be that the two of them would most likely be trapped here, and if they went to the deepest part of this cave and met the person who spoke just now, there might be a glimmer of hope for survival. Of course, if that person really wants to be unfavorable to himself, then he can only blame himself for being unlucky.

Although this cave is extremely terrifying, with hundreds of powerful bones, he is now protected by the dragon's roar, and he is not afraid of those bones.

At that moment, Zhou Tianlong dragged Yu Feilin and walked towards the depths of the cave step by step, although now all the bones were crawling on the ground, but they still added 120,000 points of caution, and did not dare to be careless.

Clear and loud dragon moans continued to come out from Zhou Tianlong's back, and all the bones lying on the ground were trembling violently, as if they were extremely afraid of the dragon moan.

"This dragon groan is really powerful, the strength of these bones is basically equivalent to the human emperor martial realm, but under this dragon groan, they don't even dare to move!" Zhou Tianlong was very shocked, and he didn't understand how this mere dragon groan could make so many powerful bones afraid of being like this.

"The strength of this True Dragon Quenching Technique and the Saint Martial Heavenly Dragon Technique is really far beyond my imagination!" Zhou Tianlong walked forward, looking at the trembling bones on the ground, and his heart was secretly shocked by the strength of the True Dragon Quenching Technique and the Saint Martial Heavenly Dragon Technique.

looked back at Yu Feilin, and saw that Yu Feilin's hands were tightly blocked in his ears, for fear of being affected by the dragon's groan. Zhou Tianlong couldn't help but feel very funny when he saw her funny appearance, and suddenly stretched out his hand and gently scratched her Qiong's nose.

Yu Feilin saw that Zhou Tianlong was still thinking about making trouble at this time, and couldn't help but feel very speechless. At the moment, his life is in danger at any time, and he can still talk and laugh, this kind of courage is really not something that ordinary people can have.

At that moment, Yu Feilin didn't have the heart to mess around with him, but just blocked his ears, and Zhou Tianlong's hand was around Yu Feilin's slender waist, and the two of them walked forward step by step.

And as the two of them gradually went deeper into the cave, Zhou Tianlong clearly heard the sound of the unjust soul crying more and more intensely, and it was faintly about to cover his own dragon groan. Just now, he had been focusing on those bones, and he hadn't listened carefully to those voices, but now that he heard it again, he felt even more hairy standing on end.

And as the two of them went deeper, the blue light became more and more intense, and Zhou Tianlong found that there were still blue flames around them that were constantly passing by the two of them, flying towards the entrance of the cave.

"If my prediction is correct, that strong blue light should be the source of this blue flame!" Zhou Tianlong nodded secretly.

The two of them went all the way to the deepest point, and they were shocked to find a huge blue flame there. The flame was suspended in mid-air, and I didn't know why it could burn all the time, as if it hadn't been extinguished for thousands of years. Blue flames flew out of the huge flames one after another, and swept towards the outside of the cave.

"What is this flame?" Zhou Tianlong and Yu Feilin were both shocked. This flame is several feet huge, and such a huge flame is the first time they have seen it in their lives. The most important thing is that at this moment, the two of them are very close to this flame, but they don't feel any high temperature, and there is even a faint feeling of coldness, emanating from the flame.

Zhou Tianlong looked around, this was indeed the deepest part of the entire cave entrance. Behind the great flames was a black earthen wall, and it was clear that there was no road ahead.

It's just that Zhou Tianlong can clearly hear that the sound of the crying soul is coming from behind the black earthen wall, and he doesn't know what terrible place is in the road.

"It's strange!" Zhou Tianlong frowned slightly: "Along the way, I didn't see half a figure at all, and the person who spoke just now didn't know where he was hiding?"

At that moment, Zhou Tianlong strengthened his courage and said loudly: "Senior, Zhou Tianlong, a disciple of the Heavenly Rain Sect, please show up and see you!"

"Haha

Zhou Tianlong was taken aback, and hurriedly looked around, but he didn't see anyone at all.

"Tens of millions of years?" Zhou Tianlong was secretly surprised, not knowing what kind of master Lu Dao was, who could survive for so long. As far as he knew, even a master of the Immortal Martial Realm, even a Divine Martial Realm, would never be able to live in the World Martial Realm for such a long time.

At this moment, a heavy sigh suddenly came, only to hear the voice say again: "It's a pity, neither of you is a fire attribute, otherwise, you may be able to fulfill my wish and help me recover that evil obstacle!"

"Senior, where are you, please show up!" Zhou Tianlong really couldn't find this person, so he asked aloud again.

"Boy, you really don't know Tarzan with eyes, I'm right in front of you, can't you see it?" the voice came again.

"Right in front of me?" Zhou Tianlong's face changed instantly, and then he carefully identified the direction from which the voice came.

"Could it be ......" A thick look of shock appeared on Zhou Tianlong's face, staring at the huge blue flame in front of him. For upon his recognition he felt that the voice seemed to come from the flame, and that the voice said that he was in front of him, but in front of him there was only this flame.

"Why, only you humans are allowed to speak, and we flames can't speak?" the voice came again.

"Sure enough!" Zhou Tianlong and Yu Feilin couldn't help but take several steps back, staring at the huge blue flame in front of them in amazement, and the shock in their hearts could not be described in words. Flames can talk about such a thing, not to mention that they have seen it, or they have not even heard of it, and they will not be able to accept it at all for a while.

"Who are you?" Zhou Tianlong's voice became trembling, and the shock in his heart was indescribable. But just after he finished asking, he seemed to feel that something was wrong, and hurriedly changed his words: "What kind of fire are you?"

Everything in this tunnel has completely subverted Zhou Tianlong's cognition. A tunnel more than 500 zhang long, hundreds of bones with great strength, and a talking flame.

"Little doll, I know you two, we met a few days ago!" The vicissitudes of life and a long-lasting voice came out of the flame again.

"What?" Zhou Tianlong and Yu Feilin only felt as if they were in a dream, and they couldn't understand what this flame was saying at all. When they had come to this tunnel, and when had they seen this talking flame, it was nonsense.

"I said, this flame senior, have you lived for tens of millions of years, and your memory is not very good! How can we meet each other?" Zhou Tianlong asked rhetorically.

"A month ago, in the Red Flame Valley, those two little dolls who came to spy on me, weren't they the two of you?" the flame asked rhetorically.

"A month ago, the Red Flame Valley was ...... Are you a fire demon?" Zhou Tianlong and Yu Feilin were so shocked that they couldn't speak at this moment, their eyes were wide open, and they felt that what happened today was really too weird, completely beyond their cognition.

According to this flame, a month ago in the Red Flame Valley, the only thing the two of them spied on was the Flame Demon. However, why did the Flame Demon appear here again? Why did its appearance be so different from that in the Red Flame Valley? Moreover, the Flame Demon had been sealed in the Red Flame Valley, so how could it be possible to escape? Zhou Tianlong and Yu Feilin's hearts were filled with too many questions, and they couldn't believe what the flame said at all.

"Almost, you humans call it the 'Fire Demon'! I am the same body as your so-called 'Fire Demon', it was born from my body, and then escaped from here and entered the world of your human beings. So what it can see, I can see, and I know you two dolls!" said the flame.

"There is such a thing!" Zhou Tianlong and Yu Feilin's faces were extremely solemn, this flame was full of truth, and it seemed that it was impossible to talk nonsense.

"Wait!" Zhou Tianlong seemed to suddenly remember something, and asked again: "According to legend, the fire demon was formed by the yin fire under the Nine Shadows, could it be that you are the Yin Fire under the Nine Shadows?"

"yes, isn't it?" the flame laughed.

"If that's the case!" Hearing the flame's words, Zhou Tianlong's face changed drastically in an instant, and his voice trembled: "So what kind of place is this? Could it be that this is under the Nine Shadows, which is the so-called 'Underworld'?"
