As he moved forward, the air was already filled with the smell of scorching, and even Lu Fan, who had been in the depths of the Flame Swamp, felt that every inhale he took was like inhaling a flame, making him feel that his entire internal organs were burning.

Boom......

The dull impact sound sounded again, Lu Fan and the two of them stumbled, and almost fell to the ground, it seemed that because of the proximity, this time the feeling of hitting Lu Fan and the two was particularly strong, as if it was a hammer on his heart, making him feel like his heart was stopping.

When the aftermath of the impact dissipated, Lu Fan and the others began to move on, and in front of them was no longer a flat plain of flames, but volcanoes that erupted or fell silent, and their vision was greatly hindered.

The two climbed a silent volcano with some difficulty, hoping to see the scene ahead and see the road ahead.

When the two of them reached the top of the mountain, both of them looked at the picture in front of them a little sluggishly, and they were both stunned.

For, in front of them, there appeared an endless group of buildings, all of which were ancient Greek buildings, all of which were magnificent and rigid pillar stone buildings.

The most surprising thing is that this ancient complex is actually surrounded by a huge volcano, which is currently blazing in the sky, and endless magma is spewing and boiling in the crater pass, staining the entire half of the sky red.

And in this crater, a magnificent ancient temple with a crystal whole body, is rising and falling in the magma, popping up from time to time, it is brilliant, there is a breath of time flowing, and at the same time there are a stream of gods in circulation.

Boom......

I don't know how long it took for Lu Fan and the two of them to wake up from the impact that shook the heavens and the earth, and this time, the two of them heard it very clearly, and they also clearly felt that this dull sound actually came from the inside of the volcano.

It's like there's a giant hiding inside a volcano, and this giant is constantly hammering the volcano, as if it's hammering the whole world of flames.

At this time, in the ancient buildings around the volcano, there are figures standing on the roofs of these buildings, looking at the ancient halls that rise and fall on the volcano, but they dare not step forward.

And they are not the only existence here, in these buildings, there are also nearly one or twenty figures of capable beasts, these powerful beasts are all extraordinary, and they are not afraid of those figures standing on the roof, but are eager to try.

If there was no ancient temple on the volcano, Lu Fan had no doubt that these capable beasts would make a move on these figures, but at this time, they were all afraid of each other, but no one acted rashly.

Because the distance is too far, Lu Fan can't see whether there is Liu Fei in those figures, for Liu Fei, this girl who is always full of vitality, Lu Fan still likes it very much, of course, it is just the kind of love for his sister.

After staring a little, Lu Fan did not hesitate, and prepared to walk directly towards the ancient complex, although they could now see the volcano, but as the saying goes, Wangshan runs a dead horse, which is the best interpretation of the situation at this time.

It will take a long time for Lu Fan and the others to reach that ancient building complex, and that crystal ancient hall, just by looking at it, you can know that it is extraordinary, if there are no treasures in it, Lu Fan will never believe it.

Boom......

There was another rapid crash, and with this crash, the magma gushing from the volcano in the distance also became even more turbulent, and the huge ancient temple seemed to be about to be thrown out.

And Lu Fan was not only excited by this, but his heart was full of doubts, because they were awakened by the sound of impact just now.

And all this, only a few tens of seconds have passed, and according to the law, the next impact should be sounded at least ten minutes later.

This impact sound gave Lu Fan the feeling that someone was using this sound to get his attention and ask him for help, although this feeling appeared a little inexplicable, but Lu Fan felt so real.

Lu Fan couldn't help but have a picture in his mind, in a long corridor, there were lattices on both sides of the corridor, and he was walking in the corridor at this time, and the corridor echoed from time to time with the sound of someone knocking on the door.

And as he passed a door, the knock suddenly became urgent, and the man inside wanted to tell him that he was behind the door.

Lu Fan was a spirit, he even felt that he had fallen into an illusion, the picture that appeared in his mind just now was too weird, but this picture seemed to be deeply engraved in his mind, making him think of it involuntarily.

Then a thought came to his mind out of thin air, and as soon as this thought appeared, it grew like a weed, so that Lu Fan didn't even rush to the volcano in the first place.

Bai Zhi obviously also noticed that Lu Fan was wrong, she looked at Lu Fan with a little frown, but she didn't rush forward, she just thought that Lu Fan had discovered something.

Turning his head, Lu Fan looked at the crater of this extinct volcano, but because this volcano has not erupted for many years, the crater is full of gray volcanic rock, and the black and dark cave mouth makes people look a little creepy.

Boom......

When Lu Fan looked at the black and swarthy hole, the dull crashing sound sounded again, but this time, the voice was obviously a lot weaker, and it didn't even make Lu Fan and the two shake again.

But Lu Fan understood the meaning of this impact, and he became more and more sure of the conjecture in his heart.

But do you want to go in or not?

Looking at the black and dark entrance of the cave, Lu Fan fell into deep thought this time, he was now very sure that the impact sound was attracting him to pass, even if it wasn't before, when he arrived at this volcano, it would definitely be.

"What did you find?"

Bai Zhi saw Lu Fan looking at the black cave in a daze, and finally couldn't help but ask.

"The crashing sound seems to be coming from here, and there may be something in there."

Lu Fan looked at the entrance of the cave and said with a tangled face.

"But didn't the crash sound sound inside the erupting volcano?"

Bai Zhi asked with some puzzlement, she still believed Lu Fan's judgment, but in the face of the facts, she couldn't help but be a little suspicious.

"I see, the two volcanoes are connected, and the thing that hit is in this passage, just because it's blocked by something, so the sound looks like it's coming from the other volcano."

Hearing Bai Zhi's words, Lu Fan suddenly brightened, looked at the black and dark hole, and became more sure of his guess in his heart.

It's just that what is the creature that hits in this passage?

And the impact sound didn't sound again, and I don't know if it was because he had no strength anymore, or because he didn't want to cause a sense of urging oppression to Lu Fan.
