Although he was in a state of invisibility, Feng Ruo didn't dare to take it lightly at all, because this Fire God Palace was formed by countless majestic and tall palaces from the outside, but when he entered it, he found that it was like a labyrinth, and the most important thing was that the materials for building the Fire God Palace were all composed of an extremely magical spar, which was born to contain infinite flames, just a palm-sized piece, and the stored flames contained in it could cover a radius of three thousand miles, and how many such spars should there be in this entire huge Fire God Palace, and how many pure flames should be stored in it？

"Could it be that this is the legendary Red Flame Cloud Crystal?"

Feng Ruo thought secretly in his heart, this thing has always been rare, and there are very few on the market, basically it is used to make fire attribute immortal runes, because this thing can store a large number of pure flames, and it has powerful lethality in itself, and it is often one of the favorite materials used by those who make immortal runes!

Like that Guan Hong, he had asked Feng Ruo to let him go to the Ghost Dragon Residence to find the ghost dragon to buy him some Red Flame Fire Cloud Crystal, and even it didn't matter if he was willing to spend his share of the Native Immortal Crystal for this reason, because this thing could not be bought elsewhere at all, but Feng Ruo was extremely jealous of the terrifying profiteer Ghost Dragon, so this matter was delayed by him, but he didn't expect to find a whole mountain-like Red Flame Fire Cloud Crystal in this Fire God Palace today, he was sure that as long as he removed a pillar from here casually, taking it back would cause a sensation in the entire Ziyao Immortal Domain！

However, Feng Ruoke would not be so short-sighted, because if the predecessor of the Fire Demon Dragon was really the fire dragon god of the Divine Dragon Clan, then the treasure here would only shock everyone. Because the Shenlong clan is born with the habit and hobby of collecting all kinds of heavenly and earthly treasures, not to mention the supreme dragon god, even if that guy can't reach the cultivation level of the heavenly immortal, but it is at least the level of the Xuanxian level, and the treasures he collects must be extraordinary!

When the Divine Dragon Clan fell before, since Haotian Lao'er got the bodies of the five dragon gods, he naturally got the treasures they stored. This constituted a large amount of Red Flame Fire Cloud Crystals in the Fire God Palace, which must be the inventory of that fire-type dragon god!

At that moment, Feng Ruo also let it go. Unleash all your divine thoughts, and while searching for the way forward, you will rush towards the depths of the Fire God Palace.

And when it comes to a certain depth. Feng Ruo found that the surrounding palace buildings began to become trance-like, constantly swaying like shadows, this is not an illusion, but because the temperature here has begun to reach a very terrifying level, even the effect of releasing water on his body is constantly disappearing, it is estimated that this temperature is Mu Qiubai drilled in, and he had to burn him half to death, and only Feng Ruo could withstand it.

This situation is perfectly normal, because even though the Fire Demon Dragon is controlled by the Haotian Demon Venerable, his habit of liking flames and high temperature environments will not change. Therefore, it can be known that the deeper you go, the higher the temperature will be, and the innermost place with the highest temperature is the place where the Fire Demon Dragon rests every day.

At this time, Feng Ruo remembered another question in his heart. That is the reason why the Fire Demon Dragon was so angry just now, I am afraid one of the reasons is that the Demon Fire River still needs to provide a steady stream of heat to the Fire God Palace.

In this way, the fiery demon dragon had to repair the source of the molten river before it could come back, which was good news for Feng Ruo!

At the moment, Feng Ruo was ruthless, and secretly said that he couldn't give up the child and couldn't trap the wolf. Now this opportunity is rare, and he has to take a risk, so he doesn't care that the effect of the water spirit is disappearing rapidly, as soon as he gritted his teeth, he continued to rush towards the depths of the Fire God Palace, and after rushing forward for a distance, the effect of the water spirit could no longer withstand the high temperature and disappeared directly. ...,

Feng Ruo didn't take the water spirit anymore, because in such a high temperature state, it was useless to take more water spirit, fortunately, he already had the fire rune, the fairy fire vein in his body was running fast, protecting the whole body, and at the same time shrouding the fire rune outside the body, and the fairy water vein was to quickly repair the burned body meridians, in short, he was no longer stealing and sneaking in, but a brazen hard break!

Of course, at this time, Feng Ruo was not too worried that the Fire Demon Dragon would find out about his existence, because now it was only Haotian's divine thoughts that controlled the Fire Demon Dragon, and this method doomed him to not be able to find some small clues, otherwise if he was replaced by the Fire Dragon God, even if it was thousands of miles away, the slightest fluctuation in his lair would not hide from him.

Therefore, Feng Ruo's forcible breakthrough this time is not whether he can be discovered by the Fire Demon Dragon, but whether he can rely on his current strength to break into the depths of the Fire Demon Dragon's true lair?

Facts have proved that Feng Ruo's concern is correct, that is, in just a few hundred zhang distance, the temperature in the Fire God Palace has increased by as much as three times! Such a terrifying temperature, it is a fifth-level earth immortal, can instantly turn into ashes, and Feng Ruo's fire rune has been consumed, but it is very strange that the surrounding palaces and the layout inside are still not deformed, but just swaying like the shadow of a flame, there is no doubt that the material quality of these palaces has reached a very terrifying level.

At this moment, every time Feng Ruo stayed here for a moment, the damage he himself suffered was very amazing, and the consumption of the immortal qi in his body was even more terrifying, if he continued like this, he would have to be burned alive!

However, the place where the fiery demon dragon lived was still far away!

What should I do? If I change to any earth immortal, I am afraid that I will not dare to go deeper, because even if I can enter alive, I will have to die to come out!

But Feng Ruo was really unwilling, he intuitively felt that the place where the fiery demon dragon lived every day had something he needed very much, this feeling was difficult to describe, not greed for material things, but like a key to open some kind of sealed door or the exit of a certain road.

"Fight!"

Feng Ruo has always believed in his feelings, and this time is no exception, at that moment he once again unfolded a fire rune, shrouded around his body, and at the same time urged the purple fire Tiansha on the necklace to absorb this wisp of purple fire Tiansha directly into his immortal fire vein, which is something he doesn't dare to think about at all, because the power of this wisp of purple fire Tiansha is too high, and it is not at all what he can withstand now, but now under the terrifying high temperature of the outside world, the existence of this purple fire Tiansha is like fighting poison with poison.

Without the tandem of the Purple Fire Heavenly Evil, the chain would naturally spread out, and the nine star sands were directly sealed and put away, so far, this chain that could open the Heavenly Immortal Great Array was completely destroyed!

With the protection of the highest level of purple fire and heavenly evil, Feng Ruo was finally able to resist the scorching temperature and continue to fly forward, but the fire demon dragon had cultivated this fire god palace too huge, and his obsession with high temperature was estimated to be perverted, Feng Ruo almost every hundreds of zhang, he had to play a fire rune, because the temperature was actually rising, Rao is he had a fire rune outside, and a purple fire Tiansha protection inside, and at the same time, there was a fairy spirit water vein to recover his injuries, and he couldn't bear it.

Finally, after Feng Ruo rushed forward for about a thousand zhang, he couldn't break through, the purple fire in his body had been exhausted, although this thing was the ultimate in fire attribute power, but the problem was that the number was only one wisp, how could it compete with this large area of high temperature?

What's more, the high temperature in front of him has reached a very terrifying state, Feng Ruo can't even see the range of twenty zhang clearly, and there is no color in his eyes, only a blazing white is left...,

"Oops!"

Feng Ruo thought in his heart, he was still one step behind, should he just go back? A thought flashed through his heart, now without the protection of the Purple Fire Heavenly Evil, his Muhuo Rune alone could no longer defend his body, and then he could see that first his hands and feet, and then his two arms and legs, all disappeared like air, and not even a little fleshy fragrance came out!

To be honest, he was able to break into here, which was enough to be proud, because even an ordinary seventh-level earth immortal would not be able to withstand the high temperature here, of course, this was not to say that Feng Ruo's strength was already comparable to that of a seventh-level earth immortal, but because he used the power of the Purple Fire Heavenly Demon, plus he was an immortal fire vein, and he also had the support of the Muhuo rune, which happened to have the conditions to resist the high temperature here, so he could reach this point!

But that's all!

Feng Ruo sighed, seeing that his entire body was about to melt like ice and snow, he activated the dragon scales on his chest, with the purple water spirit, this is his last means of life-saving, and it is also the second life, even if he is really dead, he can be reborn in an instant!

In an instant, the dragon scales that had accumulated thousands of years of power emitted a dazzling golden light, quickly enveloping Feng Ruo's entire person, and at the same time, the fairy spirit water veins also spread rapidly, and in a blink of an eye, Feng Ruo's dissolved limbs were completely replenished, this dragon scale was the inheritance scale on the body of another dragon god, and the power was not weaker than that fire dragon god, but after it was activated, the protective power emitted could only last for a dozen breaths, and Feng Ruo had to escape from the Fire God Palace again in a dozen breaths.

But at this moment, the dragon scales on Feng Ruo's chest actually flew out automatically and swept towards the depths of the Fire God Palace!

This sudden situation was really frightened, because without the protection of this dragon scale, he would definitely die! But now where does he have any choice, he can only follow the dragon scales and chase after them, so as to bathe himself in the defensive range of the dragon scales, otherwise, if he steps out of this range, it will not take too long, only a breath of time, and his whole person will be wiped out!
