In the end, Lu Fan still couldn't resist the temptation and walked into the dark hole.

And as Lu Fan advanced, the impact sound no longer sounded, everything seemed to be calm, not only in the passage where Lu Fan was, but even the volcano gushing outside began to slowly calm down, as if it was about to stop erupting.

And the figures and beasts waiting in the buildings around the volcano began to move.

Lu Fan was a little surprised to find that this hole was not vertical, but stretched downward obliquely, which also made Lu Fan confirm his previous guess, if he was lucky, he could really enter the ancient hall unconsciously.

But if they're unlucky, if the magma pours into this channel, they won't have a chance to survive, and they won't even have time to run.

But after Lu Fan came down, Bai Zhi still followed very firmly, I don't know when it started, there was already such a tacit understanding between the two.

The passage is very dark, even a little cold, and the temperature is lower than outside, obviously, not only has there been no eruption here all year round, but even the isolation has been done very well, which also makes Lu Fan more at ease.

The walls of the passage are smooth, and the passage looks a little empty except for some debris left by a volcanic eruption that I don't know how many years ago.

Taking out the queen crystal nucleus and injecting energy, Lu Fan's mind once again appeared on the three-dimensional map, and he could even feel a trace of the burning sensation of the volcano on the opposite side from the map, as well as the energy fluctuations of those people and energy beasts waiting in the complex.

But this passage was unexpectedly calm, as if this was really just a volcano that had not erupted all year round, and even made Lu Fan doubt his judgment.

After realizing that there was no danger in the passage, the two slowly increased their speed, but after a quarter of an hour, they still found nothing.

And in a quarter of an hour, although the horizontal advance distance between the two would be closer because of the downward slope of the passage, but for such a long time, Lu Fan guessed that they should have reached the foot of the erupting volcano.

But not only did they not feel the scorching heat of the volcanic rock, they didn't even feel the slightest tremor, this eerie silence made both of them a little nervous, sometimes, quiet is really not a good thing.

At this time, Lu Fan had no hope for his conjecture, but after walking for so long, it was impossible for him to give up like this, if he went back like this, Lu Fan would not be willing.

At this moment, a ray of light came from the front, Lu Fan's spirit was shocked, his speed slowed down a little, and he walked forward cautiously.

As Lu Fan advanced, the glimmer of light became more and more obvious, and there was no longer any need for the flame in Lu Fan's hand, and it was no longer dark in the passage.

Suddenly, Lu Fan took a step forward again, as if he had walked into a new world, and the front was as bright as day.

And the scene in this space made Lu Fan's mouth open wide, this is a circular space, in which all kinds of fiery red lines emit dazzling light, almost covering the entire space, like a spider web, densely packed.

And the reason why this space is so bright is also because of these lines, unlike the spider web, these lines did not make Lu Fan and the others feel frightened, and they did not seem to be dangerous.

And on these lines, there are obviously energy fluctuations, and they are even very powerful, but his queen crystal nucleus does not have the slightest sense of this, which also makes Lu Fan understand that the queen ant crystal nucleus is not omnipotent.

But looking forward, Lu Fan's face began to turn a little pale, because, on the opposite side of this circular space, there was red magma, and at this time, these magma were like waves crashing against this circular space, through the magma, Lu Fan even saw the ancient temple he had seen before sinking and floating in the magma.

But fortunately, this circular space seems to be indestructible, and those magma can't break through the blockade, almost subconsciously, Lu Fan is about to retreat.

However, it's easy to get in, but hard to get out!

Lu Fan's retreating footsteps were directly blocked, as if there was a wall behind him, and he had obviously come in from here before.

Turning his head to look, Lu Fan could only see the dark passage behind him, but he couldn't go back anyway.

Bai Zhi obviously also discovered this problem, and the blue water sword in his hand was unsheathed and stabbed fiercely into the void in front of him.

However, the blue water sword that can pierce the shell of the gold-eating ant is like wood encountering King Kong, the invisible barrier that blocks them has no reaction at all, but the blue water sword cannot advance a bit.

Lu Fan was also a little anxious, although the magma on the opposite side was blocked, but who knows how long this space could last, if the magma came over, the two of them could only be the outlaw mandarin ducks.

The energy cone quickly took shape, Lu Fan did not attack immediately, but continued to accumulate strength, his cultivation has grown rapidly for more than a month, and the power of the energy cone is also not what it used to be.

Boom......

A dull impact sounded, and the energy cone dissipated in front of Lu Fan and the others, except for a muffled sound, the energy cone did not play any other role.

Reaching forward, the invisible barrier was still firmly in front of the two of them.

Lu Fan didn't continue to attack, if the invisible barrier in front of him shook a little, he would also have a glimmer of hope in his heart, but at this time, he couldn't see half a bit of hope at all, and naturally he wouldn't do a senseless struggle, it was better to save his strength and look for opportunities.

This circular space is very large, with a radius of at least fifty meters, no, it should be said that it is a spherical space, and the invisible barrier is obviously a closed sphere, so that the energy cone that Lu Fan blasted up is also useless.

Boom......

Listening to the sound of the energy cone hitting the barrier, Lu Fan's mind suddenly remembered the sound he had heard outside before, and then pulled Bai Zhi back a few steps, his back tightly against the invisible barrier.

He knew that the sound of the impact just now was obviously coming from here, and that dull sound was similar to the sound of his energy cone colliding with the invisible barrier.

It's just that his attack obviously doesn't have the kind of power that shakes the whole world, and thinking that he has been affected from so far away, he really can't imagine how strong the other party's strength is.

But he was sure that the other party must still be here, which was why Lu Fan was vigilant.

"The young man is alert."

Just as Lu Fan was looking around, two figures appeared in front of Lu Fan, an old man and a young girl.

Lu Fan looked at the two of them with some surprise, he didn't know how the two appeared out of thin air, and what surprised him even more was that he actually knew these two people.

These two people were the old man and the girl he and Qiu Ying met when they first came out of the Flame Swamp.

It's just that at this time, the old man looked a little embarrassed, he was covered in smoke and fire, as if he had just crawled out of the fire scene, and the pale and haggard face told Lu Fan that this old man was probably already at the end of his crossbow.

Although the girl was in a slightly better state, she also looked panicked, obviously well protected by the old man, but she was a greenhouse flower who had not experienced the world.
