Thousands of feet in the sky.

A thousand-foot-long fierce wind swept through quickly, just in time to meet the colorful sky feathers that were speeding at high speed.

Ping!

There was a crisp sound like a jade falling to the ground.

The sharp wind collided with the treasure light of the colorful sky feathers, and instantly shattered into thousands of sharp wind blades, reflecting colorful light under the reflection of the slanting sun, looking at it from a distance, it was very bright.

Zhang Mu sat on the colorful empty feather, but he had no intention of appreciating this gorgeous scene, and his face was still frowning.

The reason for this was that the speed at which he was now crossing the aura with all his strength was just enough to maintain the rapid flight of the Colorful Sky Feather in the sky.

The consumption of stimulating the treasure light to resist the fierce gang wind is the aura stored before, if it only encounters one or two gang winds, it is naturally completely sufficient.

However, tens of thousands of miles away, there will definitely not be only a few encounters.

If you don't want to increase the speed of the spiritual energy crossing, and when the spiritual energy stored in the Colorful Escape Sky Feather is completely consumed, you can no longer stimulate the treasure light to resist the fierce wind, then it is almost no different from seeking death in the sky.

When Zhang Mu was contemplating and thinking, another wind struck, and after holding up the treasure light and shattering it, he silently estimated that the aura stored in the Colorful Sky Feather was less than two percent of the original.

At this time, the boundary mountain, which was tens of thousands of miles away, had only flown half the distance.

Zhang Mu weighed it in his heart for a moment, and made a decision that no one else dared to think of, taking the initiative to loosen the seal on the aura primordial dragon and increase the speed of aura overflow, so as to increase the amount of aura transmission.

After Zhang Mu made a choice, he separated a wisp of his mind and sank into the dantian, carefully controlling the three ever-changing Ganges Golden Sands Array formations, making them speed up the absorption of overflowing spiritual energy.

After the original delicate balance was destroyed, the speed at which the aura primordial dragon overflowed with aura suddenly increased a lot.

This was maintained for a while, until the speed at which the aura Yuan Dragon overflowed reached about twice as fast as before, and then it slowly stopped.

After Zhang Mu did all this, he shook his head silently, the formation base that could originally store ten days of overflowing spiritual energy had been reduced to less than five days at this time.

However, there is a gain if there is a loss, but there is no need to worry about the problem of the Colorful Sky Feather consuming aura.

A few days later.

Zhang Mu looked at the mountains in front of him that gradually flattened out, and his nervous mind began to gradually relax, and finally crossed the land of Lingzhou safely.

Immediately concealed all the brilliance on the body of the colorful Sky Feather Treasure, made it turn gray again, fell into the air thousands of feet high, discerned the direction, and began to accelerate the flight.

After two more days, he finally came to the realm where the Bloodthirsty Demon Palace was located.

Look out from the sky.

The Bloodthirsty Demon Palace, which was once built on the mountain, is now eighty percent of the buildings in ruins, and the remaining two percent are also full of holes and look crumbling.

The entire mountain has collapsed to a scale of six or seven percent, and countless ravines and deep pits are all over it.

Zhang Mu harnessed the colorful sky feathers and carefully circled in the sky, confirming that there was no danger here for the time being, before slowly descending on a ruin.

Looking around, sparkling white bones can be seen everywhere, dry blood stains are everywhere, and there are countless phosphorus fires in the distance, floating with the wind, faintly exuding a cold feeling.

Zhang Mu identified the location, and according to the direction in his memory, he began to fly towards the Demon Cultivation Cave.

Along the way, in addition to the white bones of the disciples of the Demon Palace and the corpse demons, there were also many corpses dressed in Lingzhou Daomen costumes.

Zhang Mu saw these corpses in the air, and secretly thought that when many monks from Lingzhou Daomen came to ransack the Bloodthirsty Demon Palace, they must have experienced an extremely tragic battle.

As he saw more and more corpses, he couldn't help but sigh lightly.

In the Bloodthirsty Demon Palace back then, although there was no Bloodthirsty Daoist, the Upper Realm Demon Cultivator, there were still many extremely powerful characters, and it was rumored that some of these people had even reached the terrifying Yuan Infant Realm.

With these people residing in the Demon Palace, the many monks of the Lingzhou Dao Sect who want to swallow the Bloodthirsty Demon Palace must suffer heavy damage.

Now, with the complete destruction of the Bloodthirsty Demon Palace, these terrifying existences have long disappeared without a trace.

Zhang Mu flew in the air for a short time and came to the back mountain of the Bloodthirsty Demon Palace.

Seeing the once formidable back mountain, Deng Shi remembered the scenes when he escaped from the Bloodthirsty Demon Palace, and sighed that life experiences were really ethereal.

Looking around, this place is also full of devastation now, the pits and scorch marks left by various powerful spells abound, and the cave that once hid the reincarnation array of reincarnation can not find any traces of existence, and even the huge mountain rock covering above has collapsed by a third.

Zhang Mu paused for a moment and flew towards a low ridge to the west.

At the foot of this ridge there is an extremely narrow cave gap, hundreds of zhang long, seven or eight zhang high.

Gusts of mountain wind blew through it, emitting a series of piercing low sounds, and the terrifying sound would make people's hairs stand upside down and their scalps tingle as long as they listened to it.

The place where this cave crack leads is the demon cultivation cave that even everyone in the Demon Palace talks about!

Zhang Mu came to him and saw that there was not much damage here, guessing that it should be the people of Lingzhou Daomen who saw that there was nothing worth looting in the demon cave, so they didn't make a big deal here.

Jumping in, he flew diagonally for a while, and came to the first floor of the Demon Cultivation Cave.

Looking up, clusters of faint fluorescent moss clinged to the rock walls of the cave scattered and scattered, like dotted stars, extending to the depths of the invisible.

The overall trend of the demon cave is similar to the topography of the hills, in the form of steps, extending downward layer by layer, and there is an extremely obvious horizontal cliff between the layers, and the drop difference varies from hundreds to thousands of zhang.

The space of each floor is extremely vast, the area of the first floor alone is not less than hundreds of thousands of hectares, and each floor will be several times larger than the previous floor.

Due to the special topography of the Demon Raising Cave, the strength of the corpse demon in it is also gradually becoming stronger with the continuous progression of the number of layers.

In the first layer, most of them are some low-level corpse demons with rotten flesh hanging on the ground, and ordinary strong men with wooden sticks can knock down several heads.

In the second layer, the flesh and bones of the corpse demon began to gradually become hard, and it was no longer something that ordinary people could deal with.

In the third layer, the strength of the corpse demon tends to be between innate and qi refining, and Zhang Mu was in this layer to kill the corpse demon tempered himself.

In the fourth layer, there have been occasional iron-smelting corpse demons, and ordinary foundation building monks must turn around and run away when they see it, otherwise they will most likely die under their demon claws.

Further down, there are fifth, sixth, seventh, and so on, which seem to be endless, leading straight to the depths of the nine shades underground.

Zhang Mu watched for a moment on the first floor, and when he saw a few weak corpse demons still wearing ordinary clothes, he couldn't help but show a trace of sympathy in his eyes.

The corpse demon in the demon cave is not created out of thin air, but needs to be put into it and slowly cultivated, which is why it is called the demon cave.

As for why corpses can be converted into corpse demons in the Demon Cultivation Cave, this question is unknown to the entire Bloodthirsty Demon Palace.

Once, in order to raise a large number of corpse demons, the demon cultivators of the Bloodthirsty Demon Palace kept capturing the living and putting them in the demon cultivation cave, and after the brutal slaughter, they turned them into corpse demons.

It is precisely for this reason that Zhang Mu was caught in the Bloodthirsty Demon Palace, and then because of his good qualifications, he took the initiative to become a Dinglu boy, and then survived with difficulty for five years.

Zhang Mushun killed these weak corpse demons, saving them from a miserable end that would not be peaceful after death.

Then, according to the route in memory, he flew on the rugged first layer for a while, came to the edge of the cliff, and slowly fell to the second layer close to the cliff wall nearly a thousand feet high.

It's wider and darker than the first floor.

Zhang Mu relied on the foundation building and cultivation, his eyes were like day, and he looked at it for a while, and did not find any danger, and began to fly carefully to the cliff of the third layer.

After most of the day, it finally landed on the third layer of potholes.

After Zhang Mu came here, the expression on his face became cautious, and there were almost no corpse demons on the first two floors.

But not far from this level, some scattered red dots began to move, and they were the eyes of those ordinary corpses.

Although Zhang Mu was not afraid of these ordinary corpse demons, the purpose of his trip was only to take away the sword weapon that had been hidden here, so he didn't want to add too many changes, so he hid his breath, cautiously avoided the ordinary corpse demons in the distance, and slowly flew towards the location where the sword weapon was buried.

After flying cautiously for half a moment, he came to a sunken ravine, removed a few boulders, and revealed a narrow cavern more than three feet high.

When Zhang Mu killed the corpse demon on the third layer to temper himself, he hid here.

Leaned in, traveled dozens of zhang, and came to a small cave of three or four zhang in size, looking at the dark and damp environment here, his face showed a touch of nostalgia.

Then, in front of a rock wall in the cave, he picked up the gravel in the corner and lifted a stone slab, revealing a silver-white sword weapon overflowing with cold light.

Zhang Mu picked up the sword weapon and gently stroked the sword body, and a familiar high-spirited sword intent slowly emanated from the sword.

Zhang Mu felt this clean and pure sword intent, and in his thoughts, all the experiences he had experienced after coming to this world were flashed in his heart.

Gradually, Zhang Mu's dark eyes flashed with a terrifying light, and he said word by word.

"In the future, hundreds of millions of dangers and obstacles, I will smooth them out with a sword!"

After speaking, he put the silver and white sword weapon into the storage jade ring, and leaned over and walked out of the cave.

Come to the outer room.

Zhang Muju looked at the extreme distance of the third layer.

When he was trapped in the Bloodthirsty Demon Palace, he had never been to the fourth layer of the Demon Cultivation Cave, but now that he had returned to the Demon Cultivation Cave, the sword weapon had also been retrieved, and he immediately decided to go to the fourth layer to see how the scene of the fourth layer was different from the previous three layers.

Zhang Mu flew for a moment, came to the edge of the cliff on the third floor, and slowly floated down.

The difference between the third and fourth floors is much higher than the previous floors, about 1,500 zhang.

After Zhang Mu landed on the fourth layer of the ravines, he suddenly felt a cold envelope all over his body, and he condensed for a moment, and said to himself.

"The fourth layer actually contains evil energy!"
