The Demon Dragon Flame was as black as ink, and from the outside, it looked like a sea of pitch-black fire, and from above, it looked like a demon dragon covered with black flames.

The hurricane roared at the rapid riot of this Demon Dragon Flame, Yi Nan was outside the Demon Dragon Flame at this time, and obviously felt the change of this Demon Dragon Flame, obviously because of the entry of Diyang and others, it caused the change of this Demon Dragon Flame, this is a place of creation and also a place of burial!

Yi Nan's expression was solemn, he had the Earth Cold Pearl, but he didn't plan to pass this Demon Dragon Flame directly, but to use this Demon Dragon Flame to temper his body and even let his fire spirit vein grow rapidly, Yi Nan's path was different from ordinary people, because Yi Nan's body was born with two fire spirit veins, one demon spirit vein, and one earth spirit vein!

As for the mad spirit vein Yi Nan, he didn't know what he needed to make it grow rapidly, but for the other spirit vein Yi Nan, he knew how to make it grow rapidly.

The black demon dragon flame was surging rapidly, and ordinary monks did not dare to approach here at all, of course, Diyang and the others were prepared, they were rushing through the demon dragon flame, and at this time, Yi Nan no longer wasted time, he slowly stepped into this demon dragon flame, and as he continued to approach, Yi Nan obviously felt that a terrible blazing aura was rapidly wrapping towards him.

If you are not careful, you will fall into a place of no return, this feeling is very similar to when Yi Nan was refining the earth fire, but Yi Nan has a feeling that this demon dragon flame is stronger than the original earth fire, maybe the original earth fire is not fully formed, but this is enough to explain the horror of this demon dragon flame.

A rare existence in the world of different fires, maybe one day this demon dragon flame can also evolve into a kind of different fire, of course, this will take too long, even if the current Yi Nan has a different fire he can't get it, because the current Yi Nan can't shake the different fire at all, once it comes into contact, he will definitely die!

In this way, for Yi Nan, this Demon Dragon Flame is undoubtedly the best!

Brush Yi Nan looked solemn and gritted his teeth and rushed directly into this demon dragon flame, in an instant, Yi Nan obviously felt a terrible blazing heat and quickly wrapped his body, and it was also at the first time that Yi Nan obviously felt that his body was contracting rapidly, and the blood in his body was surging rapidly, Yi Nan's face turned red instantly at this moment, and his body also appeared scarlet at this moment!

"This is not the right place, I want to enter the core!" Yi Nan said in a deep voice, and then the earth cold bead appeared in his hand, and as soon as this earth cold bead appeared, it quickly emitted a terrifying cold qi that quickly wrapped Yi Nan's body, and at this moment, Yi Nan obviously felt that his body was rapidly recovering.

Brush Yi Nan hurriedly towards the center of the Demon Dragon Flame, at this moment Di Yang and the others did not stop and hurriedly went in the other direction of the Demon Dragon Flame, they wanted to rush through this, the Demon Dragon Flame stepped on the Demon Dragon Ridge to find his own opportunity, about an hour later Yi Nan rushed into the core of the Demon Dragon Flame, an hour made Yi Nan consume a lot of aura, the consumption of this cold bead made Yi Nan also a little surprised, of course, this is enough to reflect the horror of this Demon Dragon Flame.

At the beginning, if Yi Nan, who had the Earth Cold Pearl, could completely refine the Earth Fire, but the opportunity would not come again, this time Yi Nan would not waste such an opportunity, if he could step into the tenth level of the Body Refining Realm in this Demon Dragon Flame, then Yi Nan's combat power would definitely improve by leaps and bounds, and it was even possible to resist Huo Rong.

After spending two hours, Yi Nan finally saw a darker area, all of which were black flames, and vaguely seemed to be able to see that every flame here was in the shape of a dragon, which shocked Yi Nan, but it also made Yi Nan look forward to it, and he rushed into this pitch-black flame.

At the moment when Yi Nan impacted, he felt a more terrifying burning force spreading rapidly throughout his entire body, even Yi Nan, who had the Earth Cold Pearl, obviously felt that his body seemed to be showing signs of dehydration at this moment, which made Yi Nan a little panicked. But Yi Nan still gritted his teeth, and the fire aura in his body burst out rapidly, and the next moment he rushed into the surrounding sea of fire.

But this did not make Yi Nan feel comfortable, on the contrary, Yi Nan's fire aura rushed out of his body, as if communicating with the demon dragon flame here, and suddenly the rapid outbreak of this demon dragon flame directly tore open the cold shield around Yi Nan's body, and instantly directly wrapped Yi Nan's body, and in an instant, Yi Nan felt an incomparably sharp pain that spread throughout his body.

"Damn!" Yi Nan shouted angrily.

The huhu fire storm moved, Yi Nan gritted his teeth and sat in this sea of fire at this moment, but Yi Nan didn't dare to put away the earth cold bead because he was very afraid, once the earth cold bead disappeared, he would probably be swallowed by the demon dragon flame as soon as possible and become flying ashes!

But as time went by, Yi Nan felt that the Earth Cold Bead was rapidly consuming, which Yi Nan didn't expect, but now this is the case, this Earth Cold Bead can't last long, maybe half a day will become slag, so Yi Nan must pinch and adapt to the Demon Dragon Flame here in this half a day.

"Wealth is in danger!" Yi Nan gritted his teeth, and suddenly a strange power around his body burst out, and the next moment a purple-black vortex appeared above Yi Nan's head, this purple-black vortex spun rapidly as soon as it appeared, and the next moment it burst out with terrifying devouring power!

The hurricane roared, and the terrible black flames rushed into Yi Nan's whirlpool, and with the entry of this demon dragon flame, Yi Nan's body began to tremble rapidly, if it can be seen, at this time, some of the meridians in Yi Nan's body are rapidly shrinking, and some bones are cracking, and the blood in Yi Nan's body is constantly evaporating, this qiē is because the demon dragon flame entered Yi Nan's body.

But at this moment, Yi Nan did not stop, he did not seize the opportunity at this time, once the earth cold bead was completely shattered, then it would be the time of his death, the horror of the demon dragon flame was also what Yi Nan did not expect, but now he has a feeling that it is difficult to ride a tiger, of course, the most is that Yi Nan is unwilling to give up such an opportunity.

Chance and danger go hand in hand, Yi Nan naturally knows this truth, so if it is successful, then this is chance, if it is not successful, it is death, Yi Nan's eyes are full of bloodshot at this moment, and a pair of black eyes are also showing a determined color that has never been seen before at this moment.

An hour and a year later, Yi Nan's skin cracked, his blood slowly flowed out, and as soon as it appeared, it was rapidly evaporated, and some of the meridians in his body exploded directly at this moment, and the severe pain made Yi Nan a little unbearable, but he still insisted, he believed that at most two hours, then he could fully adapt to the environment here, and then it was the time for him to really get the opportunity.

Time passed minute by minute, every second here was as difficult as ten years outside, and after two hours, Yi Nan felt his hair drying rapidly, and his teeth were a little loose, which inevitably reminded Yi Nan of what happened in the Wolong Mountains.

When he stepped into the Lingwu Realm, he was hit by the thunder tribulation, and all his hair disappeared, and now the long hair that has finally grown out seems to be about to have a catastrophe again, of course, this is secondary, the most important thing is that Yi Nan's whole body has atrophied at this time, and if it goes on like this, Yi Nan is likely to really die here.

Yi Nan doesn't regret that he didn't adapt to the Demon Dragon Flame outside, because Yi Nan doesn't have so much time to waste now, there are only two months here, Yi Nan doesn't want his two months to be spent in this Demon Dragon Flame, this Demon Dragon Flame is only the first part of the Tyrannosaurus Domain, the Demon Dragon Ridge in the back, the Tyrannosaurus Tomb in the back, and even the last Dragon Corpse Mountain Yi Nan hopes that he can go in and have a look, so Yi Nan definitely doesn't want his two months to be spent here.

Three hours later, Yi Nan seemed to be dozens of years old, and the skin of his entire body was dry and wrinkled, and at this time, there were too many cracks in the bones in Yi Nan's body, as if they would be shattered when touched, but this pain seemed to make Yi Nan get used to it.

It has been five hours since entering the Demon Dragon Flame, and Di Yang and the others have already stepped into the Demon Dragon Ridge, and at this time, Huo Rong looked at the Demon Dragon Flame not far away with a trace of worry in his eyes.

"Sixth brother, I don't know what to do now?" Huo Rong whispered.

Di Yang looked at the Demon Dragon Flame with a frown and whispered: "He can't hold on for long, if he doesn't come out after three days, I will go in to find him, you can enter the Demon Dragon Ridge first." ”

Huo Rong shook her head slightly and said, "I'm with you, it's my carelessness, I'll stay here with you, and I'll go in together in three days." ”

As for the rest of the people, they didn't say anything, they were also a little worried, but now that they are here, Diyang and Huo Rong are guarding here, they are also a lot more relieved, time is half a day in a blink of an eye, and it is also at this moment that the earth cold bead in Yi Nan's hand suddenly made a crisp sound.

Immediately after that, the cold bead in Yi Nan's hand shattered instantly, and suddenly a piece of ice appeared on the ground, and it was also at this moment that Yi Nan's closed eyes suddenly opened, and the next moment Yi Nan's eyes showed an extremely tired look, but at this moment, Yi Nan stood up violently.

But in the next moment, Yi Nan obviously found that his physical condition was too poor and too bad, but what made Yi Nan happy was that he was not instantly killed by this flame at this time, which was a hope and an opportunity.

"Come on!" Yi Nan shouted angrily, and suddenly the aura in the Tongtian Cave suddenly rioted, and it was also at this moment that a huge purple-black vortex suddenly appeared above Yi Nan's head, and then a violent devouring force instantly rushed out of this purple-black vortex, and it was also at this moment that the originally calm Demon Dragon Flame suddenly vibrate.

This scene surprised Diyang and Huo Rong!

"Well, it seems that there is no need to worry, the sixth brother has started!" Seeing this scene, Diyang was immediately overjoyed, and Huo Rong also nodded slightly, of course, if the two of them knew that Yi Nan was at the core of the Demon Dragon Flame at this time, they would definitely be shocked!
