When he first arrived, Tang Feng still decided to make plans for the situation on his side first, and he had consumed most of his qi just now, and he needed to recover, so he didn't hesitate at the moment, and his body flew back lightly.

After exiting thirty miles all the way, Tang Feng stopped, although the heat here is still there, but it can't be compared with the place just now, but you can meditate and recover.

Sitting cross-legged, while running impermanence, Tang Feng was also paying close attention to the dynamics and changes dozens of miles away. After waiting for about half a stick of incense, a pitch-black flame flashed in the sky, and it fell down like the two lines just now.

After the black flame landed on the ground, Tang Feng clearly saw that the sea of fire on the ground, which originally covered an area of only a few dozen zhang in a radius, had expanded a little. It seems that as the black flames in the sky fall, the scope of this sea of fire will become larger and larger.

But that's not right! If this is the case, then this radius of hundreds of miles should have been full of flames a long time ago, after all, the situation here has lasted for an unknown number of years, and the black flames in the sky have not known how many mortals have fallen, and they did not start when they came here.

Could it be that when the scope of the sea of fire covers a certain extent, it will disappear? Tang Feng could only think of this possibility. However, this is just speculation, and what the situation will be is still to be verified.

For the rest of the time, Tang Feng had been calculating the frequency and time of the black flame falling from the sky, but unfortunately, it didn't seem to have any rules at all. Sometimes two black sè flames fell in succession, and there was not much interval at all, sometimes it was half an hour apart, about an hour, and the longest time was that it took two hours for the second black sè flame to fall.

Every time the black flame descends, the sea of fire there grows stronger.

At the end of the day, the scope of the sea of fire had expanded to a radius of more than ten miles, and the sky was burned red by the raging flames, and the whole earth was as hot as a steamer.

Tang Feng has always maintained the realm of the middle grade of the spirit level, borrowing the corpse to return hún needs to consume a lot of Gang Qi, and resisting this unbearable scorching heat requires a large amount of Gang Qi, if it is not for the fact that he has a bad armor, and has cultivated the spirit technique, the ability of the impermanence formula has been doubled, and I am afraid that I will not be able to make ends meet.

Aside from the unbearable heat, there was not much danger in staying here, which made Tang Feng particularly reassured.

The situation of black flames falling from the sky lasted for three whole days, and the sea of fire on the ground had expanded to more than dozens of times its original size, but the further it went, the larger the area occupied by the sea of fire, the more difficult it was to expand, so now it seems that the area of the sea of fire is about thirty miles in a radius, and the scene is very magnificent and spectacular.

In three days, Tang Feng's patience was almost wiped out. Although the treasure in the center of the sea of fire is valuable, if this sea of fire does not disperse, Tang Feng will have no problem with it, and it will only be a waste of time to continue to stay here.

Wait another day, if things don't turn around after a day, you will leave! Anyway, no one in the White Emperor's secret territory can come in for the time being, this treasure is equivalent to his own if he has time in the future, and it is not too late to explore it again if he has time in the future.

I don't know if there is a providence in the dark, Tang Feng has just made this decision for less than an hour, and things have changed.

It has been more than two hours since the black sè flame has fallen from the sky, and in the past three days, Tang Feng has observed that the longest time for the black sè flame to fall is only two hours apart, just when Tang Feng estimated that the time was almost up, suddenly a muffled sound came from afar.

This voice was extremely dull, as if the heart was beating, and it was not loud, but it reached the depths of Tang Feng's heart.

With the appearance of this voice, the fire aura between heaven and earth also shook violently.

"Pounding ......" sounded again, and this time, the amplitude of the fire spirit qi was significantly larger.

"Pounding ......" is like a person coming back from the dead, and the heart that has stopped beating is rejuvenated, and this muffled sound is becoming more and more frequent and powerful.

The fire elemental became irritable, centered on the sea of fire, and quickly spread out in all directions, rolling up a red storm that swept overwhelmingly towards the periphery.

This is not an aura storm, but in terms of power and lethality, it is not inferior to the aura storm at the entrance, and the fire aura visible to the flesh eye spreads its teeth and claws, wreaking havoc on everything within their reach.

As soon as Tang Feng saw it, his face changed. If this was the aura storm at the entrance, he would probably be able to survive it with his current realm of the middle grade of the spirit rank, but the lethality of the fire aura here was too great, and he didn't dare to take risks at all.

Without any hesitation, Tang Feng unfolded his body and quickly retreated outward, the storm formed by the fire aura was like a maggot on the tarsal bone, biting tightly behind Tang Feng's buttocks, and the speed was extremely fast, even if Tang Feng did it with all his might, it was gradually narrowed closer, and in less than ten breaths, the fire aura was only about thirty zhang away from Tang Feng, as long as it took a while, Tang Feng would be bō.

Xìng's life is at stake, Tang Feng has used all his strength to eat, but it still doesn't help.

Seeing that the fire aura was about to cover itself, Tang Feng hurriedly transported out the talisman qi, hoping to resist it for a while, and at this moment, another muffled sound came from afar.

This muffled sound was stronger and more powerful than any previous one, and when the muffled sound came, Tang Feng even felt that his eardrums trembled slightly.

The heat in the sky suddenly disappeared, and the fire aura that was biting the back of his ass seemed to be attracted by something, and rolled back with a bang.

Tang Feng paused, turned his head to look at this vision, the speed of the fire aura was even faster than just now, and everywhere he passed along the road, everything related to fire was absorbed cleanly, and the clusters of small flames on the ground were instantly extinguished.

Under the divine sense, it seems that there is no such thing as fire aura in the entire heaven and earth.

After only a brief hesitation, Tang Feng immediately turned around and rushed after the fire aura.

This is definitely an opportunity! He wanted to know what treasure was hidden in the center of the sea of fire, and if he could take it himself, this was probably the only chance.

The current vision made Tang Feng eighty percent sure that his previous guess was right. When the sea of fire in this land expands to a certain scale, it will disappear, and what he sees in front of him is a sign of the disappearance of the sea of fire, and the disappearance of the sea of fire is a good time for him to do it.

Chasing after him all the way, Tang Feng no longer had to worry about the flames and flames that responded to the people. Because these things have all disappeared, turning into fire and aura gathering in one place.

The body was like electricity, leaving a long afterimage along the road, disappearing from this point to appearing at the next point, without the slightest stop. The distance of dozens of miles, under the explosion of Tang Feng's spiritual level mid-grade realm and speed, it only took half a cup of tea to arrive.

With a gentle breath, Tang Feng hurriedly searched for this vast area.

The fire aura has all disappeared, including the sea of fire that originally occupied a radius of dozens of miles, and now the entire heaven and earth are empty, only one ravine after another is presented in front of you.

A pitch-black dead tree imprinted into Tang Feng's eyes, and Tang Feng's figure flashed in front of it.

Tang Feng suppressed the jī movement in his heart, three days ago, at that shocking glance, Tang Feng saw this section of the dead tree, it was burned black, like charcoal, without any branches, it was just a black wood, but this black wood stuck straight into the ground had withstood the baptism of endless black flames without damage.

Is this a naturally generated divine weapon? Tang Feng's eyes flashed with a hint of fanatical color, and he was about to reach out to touch it, but his eyes couldn't help but aim at something next to the dead tree.

Tang Feng almost didn't bite off his tongue.

He had known that something was next to the dead tree, but he didn't know what it was. But now that I look at it, this thing turned out to be an oval egg!

A big egg with the same face as a dead tree, with a trace of black gas on it!

This egg is oval-shaped, only about half a child's height, and it is about the same size as the reclaimed stone in the phantom space, but the black gas on it makes Tang Feng feel a little worried in his heart.

This trace of black qi gives people a feeling of evil yīn sen, which is very bad.

What kind of egg is this? Tang Feng frowned and looked at it, but he didn't know it at all. Is the egg of a spirit animal left here, and is it still alive under the baptism of the black flame?

Stunned, Tang Feng released his divine sense, and couldn't help but be shocked to find that there was really a faint vitality surging in this egg.

I had the courage to reach out and touch it, and there was nothing out of the ordinary.

Weird, how can there be an egg here?

I don't know, Tang Feng didn't bother to think about it, it took several days to finally wait for this opportunity, no matter what this dead tree and black egg were, take it away first.

"Huhu ......" Before Tang Feng could start, this terrifying sound came from the sky again, and when he looked up, he saw that a black flame in the sky had already formed, and it was about to be split.

Tang Feng hugged the dead tree as fast as he could in his life, pulled it out with all his strength, and threw it directly into the phantom space, and then threw the black egg into it as well, and began to flee for his life as soon as he turned around.

But as he ran, Tang Feng discovered a strange thing, the black flame in the sky was gone, and it did not fall as before.

Involuntarily, Tang Feng slowed down his pace, looked up and observed for a long time, and only then did he breathe a sigh of relief after making sure that the black flame had disappeared for no reason.

Turning his head and looking around, this range of thousands of miles is simply barren land, probably related to the existence of the black flame for many years, but now there is no fire aura here, originally Tang Feng was still thinking that if anyone wanted to practice fire exercises in the future, he would definitely be able to get twice the result with half the effort when he came to this place, but this idea seemed useless now, and after recognizing the direction, Tang Feng walked towards the swamp along the road he came. @。
