This is a natural karst cave, full of stalactites, in a thousand forms, there are some crystalline gems of various colors on the cave wall, shining brightly, you can see clearly without seeing the realm. The air in the cave is fresh and moist and abundant, and the surface is simply a double realm of ice and fire, revealing a slight chill, the water quality of the underground river is clear, and there are some small transparent silverfish, flashing a little fluorescence in the water, like fireflies in the summer night. There are really such wonders under the Black Wind Mountains of the Hengliang Mountains.

The young man walked towards the place where the aura was strong, and the ground was eroded by the underground river all the year round, forming a round inlet, like a large and small lotus leaf in a pond, some of the inlets were shallow and bottom-seeing, and some of the inlets were dark and deep and several feet deep. The boy sacrificed the demon slaying sword and floated on the water, the young man's sword was like a boat, drifting down the underground river, turning several large caves, and coming to a huge cave, the boy couldn't help frowning.

This cave is about a few zhang high, a hundred zhang in a square circle, the ground is flat, there is a three-layer trapezoidal white jade altar in the center, each layer is three feet high, it is artificially carved, the altar is one zhang high, it is square, there are stone ladders on all sides of the altar, there are stone railings around it. The bottom floor is ten zhang long, the middle floor is eight zhang long, and the top floor is six zhang long. There is a seven-storey cyan stone tower on the top floor, the tower is seven zhang high and almost tops the top of the cave, revealing the deterrent and solemn Taoist atmosphere, the tower lintel is written with three red seal inscriptions 'Demon Suppression Tower', very obvious Taoist atmosphere, I don't know which Tianzun did it. The aura emanated from the altar and converged on the Demon Suppression Tower at the top of the altar, obviously nourishing the Demon Suppression Tower.

The underground river passed along the cave wall, and the young man floated ashore with a strong curiosity, walked towards the altar, stopped at a foot away from the altar, and observed carefully, the altar was carved from the entire white jade, and the railing was carved with simple patterns, and the aura within a radius of dozens of miles gathered from all directions to the bottom of the altar, stored in the middle layer, and then released from the top floor to nourish the demon suppression tower. The bottom layer is a large Spirit Gathering Array, the middle layer is the Spirit Storage Array, and the top layer is the Spirit Release Array.

The young man couldn't help but sigh, it's really ingenious, these three sets of large arrays will continue to support the Demon Suppression Tower, could it be that there are some demons sealed in this tower? Outside is the Ancient Giant Array, and below is the Demon Suppression Tower, it seems that there are thousands of years of time, if you accidentally trigger the mechanism, resulting in the birth of the demon, look at this posture of suppressing the demon, it is far from being able to deal with it. The young man did not recklessly step on the altar, nor did he pinch his fingers to ask about the heavens, this is not something he can covet. Look at the demon slaying sword suspended at his side, let's pull it down, it's just one of Bai Ze's ribs, even if Bai Ze is here, he doesn't dare to act recklessly!

Giving up the exploration of the Demon Suppression Tower, the boy left the central giant cave and continued to drift in the cave, and finally the river came in a larger cave, which was larger than the previous giant cave, but there was no ground, but a huge lake, which operated as if it were nothing, the water was dozens of feet deep, and there was a cave at the bottom that was connected to the outside, and the boy remembered that after the Tiger Roaring Ridge, there was indeed a lake about several miles wide near the Black Wind Mountains, which should be the exit.

——————

After the young man examined the entire cave back and forth, he did not go to the central giant cave, but found a small cave that was relatively flat, sat down cross-legged, and took out the few loot in order to confirm the identity of the killer, the trophies were a flying sword, a bamboo whip, two jade bottles, and two treasure clothes. The flying sword was metallic, summoning gold, and gold looked at the flying sword with a flattering look.

The young man had a bottom in his heart: "Jinzi, look at this flying sword, how is it in condition?"

"This flying sword has average combat power, but it is a tracking flying sword, which can conceal itself and track hundreds of miles without the prey noticing, and the name should be 'Shadowless Sword'. "Kaneko said.

"Is that if you swallow this flying sword, you can also hide yourself?"

"That is, but it can only be used against monks who are not as good as themselves, and I used to devour a higher-level secret spell ten thousand years ago. Jin said proudly.

"Okay, since that's the case, then this sword will be given to you!" The young man directly said that the sword was handed into the mouth of the gold, and the flying sword disappeared in an instant, devouring it completely, as if it disappeared out of thin air, the gold showed a satisfied expression, the young man couldn't help but be a little afraid, if there are any good things in the future, he must think about it, otherwise he will not regret it if he enters the mouth of the gold.

"Kaneko, can you show me the Meteor Sword?" the boy asked.

"Of course, you see, master!" In order to have a stronger metallic treasure devouring in the future, gold must perform well in front of the master, only to see the silver-white villain suddenly disappear, a flying sword appeared out of thin air, it is the meteor sword, the sword body shook, a sword turned into a thousand small swords, the next moment, a thousand small swords all disappeared, the young man quickly opened as if nothing, captured a thousand flying swords shuttling in the cave, and instantly appeared on the stone wall of the largest giant cave, a large humanoid pattern appeared, the pattern was all composed of dense sword points, the next moment the meteor flying sword was suspended in front of the young man, and in the next moment a silver villain stood out of thin air, showing pride。

"Okay, you, Jin Zi didn't see it, the three hundred and sixty flying swords of the clone were actually promoted to one thousand and eighty by you, and the golden hidden characteristics of the shadowless sword were added! The boy was surprised, it was more than he could have imagined.

"Master, you are also amazing, you can count the number of thousands of flying swords in an instant, and you can also catch Jin Yin, you are worthy of being my master. "Gold's kung fu is also first-class.

is worthy of being a killer at the level of the infant, the two flying swords are simply the holy products of the sneak attack, and the person who was assassinated has no luck.

"Come on, there will be something for you to eat in the future, gold, do you see those ancient gods outside, one piece is tens of thousands of catties, all made of immortal iron. The boy asked.

"Of course, but those ancient gods, the sword spirit is long gone, the sword has no soul, and the taste is very ordinary. Jin Zi said with some regret.

"Tens of thousands of weapons don't have souls, so where are those souls?" The young man suddenly thought, if the soul of the sword is destroyed, the sword as the main body will be shattered, since the main body is still there, could it be that the Demon Suppression Tower is the spirit that seals these weapons, could it be that these weapons are all weapons of the demon race? There is such a possibility! This can only be confirmed later.

——————

The boy picked up the bamboo whip again, the bamboo whip has a total of twenty-seven sections, the bottom three sections are polished into handles, there is a kind of bamboo called iron whip bamboo, the pagoda-shaped is divided into eight edges, the middle is solid, there is thickness, a hundred years of a section, three thousand years of talent, into a sword type, tenacity is better than iron, five thousand years into a demon, ten thousand years into a fine. The young man went into the microscopic probe inside, and sure enough, he saw a bamboo spirit asleep, and he didn't know what kind of sword spirit was in this bamboo whip.

Except for the magic weapon of metal, gold has no interest in magic weapons of other attributes. The young man couldn't ask why, so he kept it for the time being and refined it later.

Picking up the porcelain bottle, after opening it, the young man couldn't help but be shocked, could this be the big return pill, after the subtle investigation, there is no doubt that the young man is familiar with the small return pill, and the small return pill contains the power of seeds. And this pill is twice as big as the small pill, and not only is the power of the seed more abundant, but also a restless vitality emanating from it. This killer really has a treasure, maybe it was obtained by killing people and selling more goods, and the other porcelain bottle is also a big pill. The young man suddenly remembered Murong Qiushi, I don't know if this benevolent brother has recovered, the power of the lightning strike is not small, hey, he and Nanhua Palace have become fire and water, even if he goes to Nanhua Palace, he will not be able to see Brother Murong, not to mention that the Nanhua Palace sect is strong, there will always be a cure pill.

In the end, the young man picked up the two magic robes, and he didn't seem to see any doorway, and they were also temporarily stored, after all, this set of river demon armor on his body was made by Sister Su in a hurry, and every scale was polished, the defense effect was good, the style was also exquisite, and there was also a trick to avoid water, which was also a common talent of river demons.

After inspecting the loot, the young man took out the jade slip of the communication, and thinking that there was no information about the killer, he wrote: "An! There is no mention of the information about the karst cave under the volcano and the demon suppression tower, for fear of worrying about the uncle, and also for fear of revealing the heavenly secrets, such a battle to suppress demons is not something that can be touched by the mortal world, and the Three Realms may be shaken, and the flooding of the river Jiaohe River is nothing compared to it.

Soon after, the message from the summoner replied: 'Hostile, do not reveal your whereabouts!'

After seeing the reply, the young man regretted a little, he should not have informed several disciples of the Dai Sect of his whereabouts and purpose, it might harm them. After pondering for a moment, reply: 'Yes'. It seems that it is better to hurry up and find the magma fire spirit in the volcano, and upgrade the magma fire spirit sword to the fire spirit as soon as possible!

——————

The young man sat cross-legged, running as if he had nothing, and entered the Jindan realm, the detection distance has been nearly twenty miles, just enough to cover the entire volcano, in the crater down is a hundred zhang deep volcanic well, thick smoke gushes out from the well and falls around, below the volcanic well, there is a huge magma cave hundreds of zhang wide, there is a magma lake inside, the red magma is churning and flowing, it is the red flame beating on the surface of the lake, and from time to time there are bubbles coming out, bringing out ash and black smoke. Looking into the depths of the magma, sure enough, there were fire spirits swimming in the magma like fish, looking downward, like the deep sea, there was no end, and the color of the magma also turned from red to incandescent white, and the twenty-mile detection distance had come to an end.

Retracting his gaze, the young man was overjoyed, and sure enough, he found the right one, and immediately sacrificed the magma fire spirit sword, blessed the earth escape technique, the nature of the magma fire spirit is stone and fire, and naturally the earth escape attribute can be attached, but the speed is slow, which is also much more secretive than flying into the crater from the air, since he fought with that infant-level killer, the young man had to guard against it.

After an hour of earth escape, the magma fire spirit sword finally escaped to the bottom of the magma lake, back to the birthplace, the fire spirit sword like a fish returning to the sea bird into the mountains and forests, leaving this place for a hundred years, happily swimming in the magma, the young man can clearly feel the joy of the fire spirit!

"Don't just play around, there's a fire spirit in front of you, haha, delicious!" The young man saw that the fire spirit actually had a feeling of hunger in his heart, which was also a feeling connected to the blood of the Fire Spirit Sword.

The Magma Fire Spirit Sword immediately comprehended its master's intentions and quickly moved closer.

The young man's heart was suddenly moved, thinking that the Lingkong Dao Master had said that the ghost demon can only generate a powerful ghost demon by devouring the demon that is slightly weaker than himself, and I don't know how many fire spirits there are here, so that those fire spirits can devour each other and strengthen themselves, and then the fire spirit sword will devour that powerful fire spirit.

As soon as the young man's mind moved, the Fire Spirit Sword immediately understood the master's intentions, and immediately carried out the plan to drive the tiger and devour the wolf, driving the fire spirit to devour each other, and then devour each other.

The detection distance of the young man is limited, and the detection distance of the divine consciousness of the Jindan Realm is only one mile, and it cannot penetrate deep into the scorching magma, otherwise the divine consciousness will be damaged. However, the magma fire spirit sword is infinitely increasing the space for movement, and the sword body quickly falls out of sight with a twist, leaving only a trace of induction to connect with the owner. The boy was no longer able to control it, and relied entirely on the Magma Fire Spirit Sword to complete the devouring of the fire spirit and upgrade to the fire spirit.
