Although there is a jade slip to introduce the situation of the cave, because of the collapse of the secret realm, the cave has a lava eruption, and the landscape has changed greatly.

Niu Lao Mo walked briskly in a rather spacious cave passage, the walls of the passage were made of gray rocks, with their knowledge, they naturally knew the Broken Dragon Stone, but they didn't know the refining effect of the Broken Dragon Stone.

It was precisely because they recognized the Broken Dragon Stone Passage that they judged their position and frowned overjoyed.

There is a clear record in the jade slip that after the end of the Broken Dragon Stone Passage, it is the deepest part of the cave, and the pure true demon water is there.

The Broken Dragon Stone is made of hard material, and it does not have the slightest transmission effect on any mana and magic power, and the rock passage formed by it can naturally block the divine sense.

Everyone was in an anxious mood, and after another seventy or eighty breaths, the eyes suddenly opened up.

Entering their field of vision was a vast space, about the size of dozens of zhang, and there were two rock paths in the cave, in the shape of a cross, and in the four directions of the cave, that is, where the cross road was not covered, were lava fire pools.

It seems that the temperature of the lava here is much higher than that outside, and the old demons can keenly sense that the lava pools around the cave have been emitting a strong demonic energy.

And all of this demonic qi surged towards the middle of the cross passage.

There, there is an extremely eye-catching silver and gray two-color light curtain, through the forbidden light curtain, the three of them can completely see the scene inside.

To the left of the light curtain is a square pool of water that is one zhang long and wide, filled with a deep purple mist.

Around the square pool, various intricate runes are carved, and many lines are connected to its right, where a very delicate white jade basin is placed, which contains half a basin of pure black liquid.

"Purple-black demonic energy, true demonic energy! That's right, that's the real demonic pool water!"

"In the jade basin next to it, is it the pure true demon water?"

"There are so many!"

Everyone was directly attracted by the scene inside the light curtain, and even without the guidance of the jade slip, they could judge that what appeared in front of them was exactly what all the Demon Cultivators dreamed of.

Old Devil Niu coughed lightly and said: "Two, time is pressing, let's find a way to deal with the ban in front of us, that old guy just came here at the beginning, and there was no temptation at all." ”

Leng Feiyan was eager to try: "The environment here is very suitable for the flame demon blade of the concubine's body, so let the concubine try this forbidden light curtain." ”

The old demon and the masked man naturally had no opinions.

The magic power in Leng Feiyan's body surged, and a dark red meniscus knife flew out of her body, this flame demon blade was clear, and there was a faint black flame in it, which was her natal magic weapon.

This well-known Demon Flame Fairy in Xizhou pinched it, and a pitch-black flame immediately emerged from the Flame Demon Blade, and it seemed to feel its surroundings, mixed with a joyful chirp, and blasted towards the forbidden light curtain in front of it.

With a "boom", the Flame Demon Blade struck the silver and gray shield, and at the same time, a jet-black demonic flame poured out from the Demon Blade, enveloping the forbidden light curtain.

Leng Feiyan seemed to sense something, her face was a little ugly, and she summoned the Flame Demon Blade back and levitated in front of her.

The forbidden light curtain in front of him did not change after being attacked.

Seeing this, the other two's faces changed, although Leng Feiyan's blow just now did not use all his strength, but it was blessed with the Demon Flame Divine Power, and the attack power was not weak at all, but the aura of this light curtain actually showed no signs of weakening.

Leng Feiyan frowned and said: "Old Demon Niu, this prohibition is extremely powerful, it seems to be far beyond the level of the Yudan stage, even if it is a shield that can resist the attack of the Yuan Infant Stage, under the effect of my attack, it is impossible to change without change." ”

The old demon muttered, "No wonder the Molten Demon Crocodile didn't covet that pure true demon water, it was protected by such a powerful prohibition, but it shouldn't be......"

The old demon couldn't help but walk around in place, as if he was bothered by the question.

The masked man also spoke up: "It's indeed a bit strange, as far as I know, every time in the secret realm, there are demon cultivators who have obtained the true demon water, and not all of them have obtained it from the Ancient Demon Cultivation Cave Mansion. ”

Leng Feiyan's eyes lit up: "What does Sha Daoyou mean is that there is a demon cultivator who has taken the pure true demon water from a similar prohibition in front of us?"

The masked man nodded and said, "There are some records in this sect, saying that there are many true demon pools in the secret realm, and along with the true demon pools, there are purified true demon water. ”

"The three major demon sects are extremely powerful, and every time the secret realm is over, there are demon cultivators who have entered the Yuan Infant Stage, they must know the location of one or two true demon pools, and they have a way to penetrate this forbidden light curtain. ”

Leng Feiyan muttered: "Then what kind of means is it, the strength of the Blood Refining Sect is at the top of the three sects because of the Pang Old Demon and the Blood Demon Skill, but the comprehensive strength of the other two sects is not much different, so this method must be shared by the three sects." ”

Hearing this, an electric light flashed in the mind of the old demon who was pacing in place, and he said with a happy face:

"Two fellow Daoists, the strength of this prohibition exceeds the level of the Yuan Infant Stage, in the secret realm, we have also encountered a forbidden light curtain, which is also impossible for the Yuan Infant Stage monks to break, and we have also passed the prohibition together. ”

Leng Feiyan and the masked man blurted out after this reminder: "One yuan jade pendant!"

Niu Lao Mo laughed and said: "That's right, although this forbidden light curtain looks different from the outside, the silver luster inside is very similar, we can try it with a one-yuan jade pendant." ”

Leng Feiyan hesitated a little and said, "But what if we are teleported away like the prohibition outside the secret territory?"

Niu Lao Mo had already taken out a jade pendant at this time, and he walked forward: "Hehe, if you don't worry, let Lao Niu give it a try." ”

As he spoke, Old Demon Niu began to inject magic power into the one-yuan jade pendant, and after a while, the one-yuan jade pendant bloomed with a soft white aura, and he looked slightly expectant and leaned forward the white aura.

As a result, the silver-gray prohibition immediately changed, and the forbidden light curtain immediately dissipated half of it after it came into contact with the jade pendant aura, but then there were no other changes.

"It worked!" the three of them looked happy.

"Attack again!"

Leng Feiyan struck out her Flame Demon Blade again, bombarding the weakened light curtain, but although the forbidden aura weakened, it was still helpless for a cultivator like them.

When the masked man saw this scene, his exposed green eyes lit up: "Will it take two one-yuan jade pendants to work together?"

"Sha Daoyou is reasonable. ”

"A quarter of an hour has passed, Sha Daoyou, you and I will break the formation together, and we still have time to escape after obtaining the True Demon Water. ”

But just as the masked man took out a jade pendant, the lava pool in one corner of the cave suddenly boiled, which made everyone who was nervous look startled, and they all stopped their movements and looked at the lava pool vigilantly.

As the magma in the lava pool boiled, it seemed that a figure appeared under the lava and swam towards the rocks at the edge of the pool.

"It could be a molten demon crocodile!

Leng Feiyan's eyes narrowed, the flame demon blade in front of her exuded an amazing coercion, and shot towards the black shadow, her magic weapon was not afraid of lava, even if she entered the magma, the power would not be reduced in the slightest, it was very suitable for her to take the lead in attacking.

There was a loud bang, and the lava pool was hit by the power of the magic blade, and a large amount of magma splashed out.

Then the three of Niu Lao Mo seemed to have seen something incredible, their pupils dilated, their mouths slightly open, and they looked in the direction of the lava pool in disbelief.

I saw a thick arm stretched out from the lava pool by the edge of the lava pool, and there was still a little lava left on it.

Although it looked similar to an ordinary human arm, everyone clearly felt a majestic coercion appearing on it, and there was a faint treasure light emerging from this arm, and it seemed to be a top-notch magic weapon.

And Leng Feiyan's Flame Demon Blade was being grabbed by the thick palm at the front of the arm, and the sharp blade only cut through the skin on the fingers, as if there was nothing to do about this palm.

From the slightly trembling blade, everyone even heard a trace of wailing.
