Yi Heng found that the aura here was extremely rich, definitely far more than any place he had experienced.

But the cave is full of blood-like rocks, and I don't know how they came to be.

But at this time, it is not the problem of walking back and forth, but the problem of recuperation and healing.

There are also countless small holes in the walls of the four caves, and there is no problem with accommodating one or two people, but there are many monks who come in, and they don't know where they are all teleported.

And how to walk in this secret realm, how to find opportunities?

It is rumored that anyone who is not a monk in the Jindan stage will definitely die, even if it is in the Yuan Infant Stage, the Transformation Stage, or even a higher cultivation.

He carefully observed the ground, and there was no vegetation or dust on the rocks beneath his feet.

The only thing that was there was blood red, and the whole cave was blood red, not the most vivid blood, but as if blood was pouring on the stone, and it was like it was immersed in the stone for a long time.

Dark red, the ubiquitous dark red, makes this silence even more terrifying.

"Could it be that this is the blood stains left by monks entering this place for thousands of years?" he shook his head, no way.

In the whole cave, there were no corpses to be seen, not even a trace of dust, how could it be left by monks?

The liquid was concentrated on the right foot, and I tried to step on it so hard that I didn't move a single bit.

Greatly surprised, he rubbed his right foot hard, and the sound of "zizi" was made, but it was the sound of the soles of his feet rubbing against the rock, and the rock was not damaged at all, not even a little powder.

This made him shocked, and then he stopped worrying about crushing, and gradually increased his strength, and finally, he carried all the spiritual fluid, and the dark red rock under his feet was still undamaged.

He couldn't help but look at the entire hole in front of him, like the old woods, wild vine-like rock nets, his eyes showed a look of horror, could it be that these rattan nets couldn't shake a bit?

From the time he came in to this time, he didn't dare to make any movement except for stepping on the rock at the bottom of the cave with his right foot, and looked at him like a fool.

At this time, his spiritual sense had already been released, and it was roughly the same as here in the range of three hundred miles, no matter before or after.

"Is this not a hole, but a passage?" he immediately wondered, if it was a passage, where would it lead?

And where are the millions of monks who have been teleported in now?

Where is the so-called test, the so-called treasure of heaven and earth?

Since there was no sound, he sat cross-legged and began to heal.

Three days later, the wounds on the broken sternum and internal organs gradually stabilized, and at least he had the strength to fight in the face of danger, and he secretly breathed a sigh of relief.

I just opened my eyes and looked at the passage, not knowing which way to go.

You have to find a secret place and advance to the Jindan period, otherwise, the rumor that you will die if you come in the non-Jindan period has been stuck in his heart, so he doesn't dare to make any moves.

Suddenly, his complexion changed, he prostrated his body, put his ear on the pipe, and felt a sound of "boom, bang" from a long distance.

At the end of the spiritual sense, there was still no figure or movement.

When he raised his head, his face was shocked and frightened, because at this time, he felt that the sound was getting closer and closer to him, and the pipe the size of his feet gradually trembled.

"Monk, fighting method?" He immediately knew in his heart what was going on, and the number of monks who had entered this room was definitely beyond his imagination.

After coming in, I didn't encounter it for the first time, it was already very unexpected, and now there is a monk fighting, which is naturally very normal.

It's just that the monks who came in were almost Jindan monks, and this fight was getting closer and closer, if it was affected, how could it make it better for him?

Thinking of this, he didn't hesitate anymore, since the sound of the fight was ahead, he ran to the back, only hoping that this passage was not too short, and only hoped that their fight would end quickly.

Standing up, patting Qiu Xiyin behind him, unfolded his body, and passed through the chaotic stone and rattan nets.

Under the Dao Yun, in the stone rattan net that blocked the way, although he could not fly quickly, it could not prevent him from passing through quickly.

I saw that his figure was left or right, up or down, constantly passing through the gaps in the rattan net, and sometimes falling directly under the pipe, constantly leaping and leaving quickly.

An hour later, he was already a hundred miles away, but to his horror, the sound of the fight was not over, but was getting closer and closer.

Looking behind him in disbelief, he scanned all the way up, down, left and right, and fell under the pipe, wondering if he could hide under the pipe, but then he was disappointed.

The spiritual sense is swept away, all of them have nothing to hide, there is not even a place to hide here, there are countless large and small stone caves on the cave wall, but what is the use of the stone cave that can even see the bottom with the naked eye?

As a last resort, he turned around and fled again, not daring to stay all the way.

After a few hours, a hint of joy appeared on his face, and five small pipes appeared in front of him diagonally upward, and there were countless stone bars connected between them.

He didn't hesitate, chose one, and immediately rushed up.

However, after a while, he hesitated again, and five forks appeared in front of him, the first one was slightly wider, about three feet, and the back gradually became smaller.

But the smallest one is more than a foot in size, and there is absolutely no problem for two or three people to hide.

After thinking for a moment, the sound of the fight was getting closer and closer, and the sound of spells and magic weapons trying to collide was faintly heard, this should be a fight between monks with little difference in strength, otherwise how could it last so long?

But after a few hours, it has been more than 500 miles away from where I meditated, and I am still fighting, is it because I have encountered some natural treasure and started to fight?

Just looking at this cave, where is it possible to grow any natural treasures?

Gritting his teeth, he turned around and drilled into the penultimate fork hole, not daring to choose the first or the penultimate one, thinking that the two of them would fight here, and they shouldn't just enter his fork.

This penultimate fork hole is not small, it is nearly two zhang wide, even if you enter it with Qiu Xiyin on your back, you can leap forward quickly.

An hour later, he stood above the pipe, his face gloomy.

At this time, in front of him, it was no longer the passage, but the end of the passage, which meant that he had no way out.

Although the spiritual consciousness has known it for a long time, when it is really here, and the fight between the two has not ended, I can't help but feel helpless.

With a "bang", a cloud of sparks appeared in the slightly gloomy passage, but it was he who sacrificed his magic weapon, the purple gold flying sword, and stabbed the sword at the end of the cave wall.

But to his disappointment, the dark red rock on the cave wall had no trace of it except for a cloud of sparks.

Although he had already been mentally prepared after coming in and finding that the walls of the cave and the top of the pipe were extremely smooth, at this time, the facts in front of him still made him desperate.

Turning around, the sound of a fight came from the pipe, and at the end of this passage, it still felt obvious.

The figures of the two monks had already entered the spiritual sense, and at this time, he knew why these two people kept fighting at him.

I'm afraid that at some point before, the blackfriar was already invincible, but he should have vaguely discovered his existence, or deliberately sought out other monks.

Fleeing as he fought, he kept coming towards the passage.

Obviously, they want to cause trouble, or find a helper.

There was a coldness on his face, and he wondered what kind of expression the black-clothed monk would have after seeing that he was just building a foundation and cultivating?

Two hundred miles, one hundred miles.

The blackfriar's face changed drastically, and he was slightly distracted by the scars, and he was even more severely injured.

A whip-like magic weapon passed through the lower abdomen, bringing out a canopy of blood, which instantly fell on the pipe, and quickly disappeared, only to make the dark red on the rock pipe a little bright.

The blackfriar covered his lower abdomen with his right hand, pointed in his direction, cursed in his mouth, jumped up, and drilled into a small hole in the cave wall.

Yi Heng was dumbfounded, how could he hide from that small hole?

But to his shock, the blackfriar disappeared as soon as he entered the small hole in the cave wall.

"Disappeared?" He rubbed his eyes vigorously, in fact, it was just a subconscious movement, more than a hundred miles, invisible to the naked eye at all, in his spiritual sense, the black-clothed monk had indeed disappeared.

The monk who was chasing him also looked in the direction where he was with a fierce face, as if he was thinking for a moment, but then he also rose up and ran towards the small hole where the black-clothed monk had disappeared.

Without warning, it disappeared in an instant.

Shocked, he withdrew his spiritual sense, looked around the place where he was at this time, and found that after reaching the end, there were not many small holes in the cave wall, but there were two or three.

At this time, he knew where all the people who had teleported in had gone.

If these little holes can teleport people to other places, and each little hole can go to one place, how many small holes are there?

Judging from the few hours of running just now, there are countless small holes on the wall of the cave all the way, some are large and some are small, but it is absolutely certain that there are tens of thousands of such holes.

And the place where he ran may only be a small part of this secret realm, which can explain that so many monks have probably entered the small hole in the cave wall.

Perhaps, that test, that heavenly treasure, is in the small hole.

Perhaps the danger of the death of the monk is also in the small hole.

He looked in horror at the wall of the cave in front of him, only a few feet away from him, and couldn't help but take two steps back, because there happened to be a small hole there that could only hold one person.

Fortunately, no matter what happened before, he was the most cautious and did not approach the cave wall, otherwise he would have been teleported to nowhere, wouldn't he have died in an instant?

Turning around and looking at the cave wall at the end, fortunately, there were no such small holes around the cave wall at the end of the road.

Now, although he knew that after teleporting into this small hole, there would definitely be something exciting, but there would be a life-threatening danger, so he naturally didn't dare to trespass without permission.

I can't say it, only when the pill is refined here, and I marry Xi Yin here, and then I think about not being able to enter the small hole.

Suddenly, he remembered something, and with a pat of his left hand on the spirit pet bag, a silver flying insect flew out with a "buzz".

Stretching out his hand, the flying insect half the size of the baby's small fist stopped in the palm of his hand, which was the gold devouring insect.

Attached a trace of spiritual sense to this insect, and then pinched his fingers, and with a "buzz", the silver flying insect flew from the palm of his hand and flew towards the small hole in the cave wall in front of him.

I was a little nervous, and my eyes were fixed on the silver gold-eater, and I saw that it had just flown into the small hole, and suddenly disappeared.

Not only is it invisible to the naked eye, but it can't even feel its spiritual sense, and the trace of spiritual consciousness attached to it is naturally useless.

It's too mysterious, if it's teleportation, but there is no teleportation movement, but it's more like being swallowed up by space, which really frightens him.

Now I don't face this small hole anymore, I don't know if it's a mental effect or it's true, I always feel a trace of attraction from that little hole, and I want to swallow him up.

Turn around and walk towards the end, there is no small hole in the wall of the cave at the end, and it looks like it should be much safer.

took out the futon, put Qiu Xiyin down, lay down against the cave wall at the end, and saw that she looked peaceful and was in a coma, so he whispered to her.

Half an hour later, it was found that it was very remote, and no one came back except for the two monks.

Immediately took out the Dan furnace and spirit charcoal, took out the jade slip given by Gou Youwei, and began to figure out the Dan recipe, preparing to refine the Zihong Spirit Pill.

The Purple Rainbow Elixir can increase the success rate of the elixir by one to five percent, and it is a must-have pill for monks.

Except for the very well qualified, no foundation building monk dares to say that he is 100% sure that he will succeed.

If the qualifications are too poor, such as the three spirit roots and four spirit root cultivators, they need a large number or higher grade Zihong Spirit Pill, otherwise the cultivation will be lost, and the worst will be killed on the spot.

Therefore, many monks are desperately pressing when the foundation is being built

Impulsively, he kept polishing the foundation and suppressing the spiritual fluid, and finally dared to try.

And the five spirit roots, not to mention the knot, even the foundation building is probably very few.

He quietly pondered the information he had been collecting bits and pieces, and secretly calculated in his heart.

With his spiritual root, he has been able to build a foundation to get to the present, not to mention that there is no one in the world of cultivating immortals, but there are absolutely few and very few, and most of them are people with deep opportunities.

And when it comes to the end of the Dan, I am afraid that it is the feather phoenix horn, which is difficult to have one in a million.

But it was nothing, he clenched his fists hard, he not only wanted to tie the Dan, but also to keep going.

Where is the Book of Changes? Where is the way home? If you don't even find the Book of Changes, how can you give up easily?

After a stick of incense, he finally calmed down and carefully studied the Dan Fang, as well as the details paid attention to in the alchemy.

The difficulty of refining the Purple Rainbow Elixir was far greater than that of the Zhuji Dan, and there were as many as one hundred and thirty-one elixirs needed, and they were all medicines that were difficult to find.

But with the support of a large number of spirit stones, he spent 250 million spirit stones to prepare fifty copies of the best elixir, all of which were more than three hundred years old.

But these fifty copies will definitely not be successful, and some hands must be practiced, but fortunately, twenty copies of the elixir that has been practiced for decades or so are also prepared, and it should be about the same for hand training.

Otherwise, if you start directly, you will definitely feel heartache if you use an elixir of more than three hundred years old, a copy of five million spirit stones.

Two hours later, after studying the Danfang, his face was cloudy, and after thinking for a moment, he put the Dan furnace and the spirit charcoal into the storage bag.

It's not that he wants to waste time, but the complexity of alchemy is far beyond his imagination, what pills to put in every step, and to what extent to refine them, are all very strict, and if you make a mistake, you will give up all your efforts.

It is not enough to throw all the elixirs into the Dan furnace, and the requirements for the strength of the soul, the subtlety of the soul control, and the subtlety of the alchemy technique are extremely high.

At this time, his spirit and soul had not recovered to the peak, so he naturally did not dare to open the furnace for alchemy, otherwise it would be a waste of elixir.

And here, if the elixir is wasted, there will be no chance to buy it, so what can you do if you have no spirit stones?

If you really get to that point, I'm afraid you will have to wait for death.

Leaning against the wall of the cave and closing his eyes, although he was in an extremely unfamiliar place, he basically knew that the danger here was in that small hole, and there was no need to worry.

After a while, he gradually fell asleep.

There is no day and night in the cave, five days have passed, this place is indeed extremely remote, and in the five days, except for Qiu Xiyin, who is in a coma and sleeps beside him, everything else is extremely silent.

When he opened his eyes, he suddenly felt extremely energetic, and the villain in the Purple Mansion sat cross-legged on the ground, full and solidified, his hands constantly pinching his fingers, and constantly cultivating the soul technique.

But it seems that cultivation is limited, the size of the villain has not changed, the only thing is that the body is stronger.

The soul power obtained from cultivation was transmitted into the Bagua Plate one by one, replenishing the soul power that had been lacking for a long time.

Stretch your waist, don't think too much, immediately take out the Dan furnace and spiritual charcoal, and start to light the charcoal at a distance from the end of the cave wall, and put the Dan stove on the rack.

With a touch of his left hand, an elixir for refining the purple rainbow elixir appeared on the ground, which was used to practice his hands, and the elixir for about twenty years was worth 500,000 spirit stones.

Generally speaking, no monk would use this elixir to refine the Purple Rainbow Elixir, because there was almost no success rate, the elixir year was too short, and the medicinal properties were not enough at all.

And when such elixir is collected, it can only be used to practice hands.

He swept his eyes, and immediately found the main medicine in it, Zihong Qilian, and gently picked it up with his left hand, this elixir that grew on the snowy mountain and was deeply covered in snow was also very difficult to find.

Looking at the size of this plant in his hand, it is only about twenty years old, but the smell of medicine enters the nostrils, but it feels extremely cool, and the whole body is comfortable, and even the spiritual liquid in the dantian that is about to solidify is slowly fluctuating.

After half a cup of tea, the spirit charcoal began to emit a constant temperature, completely preheating the Dan furnace, and the spiritual sense probed towards the Dan furnace, feeling that the temperature was still not enough, so he could only recall the steps of refining the medicine and wait patiently.

After dozens of breaths, he no longer hesitated, with a flick of his left hand, he immediately threw the Purple Rainbow Qilian into the Dan Furnace, and the spiritual sense tightly wrapped the Purple Rainbow Qilian, so that it would not fall into the bottom of the Dan Furnace, but hang in the middle of the Dan Furnace and slowly temper it.

Time passed slightly, the purple rainbow qi lotus slowly melted into a liquid state, and a strange fragrance wafted out, but he was unmoved, and his spiritual sense wrapped the few drops of the liquid that the purple rainbow qi lotus had turned into, and slowly approached the bottom of the Dan furnace to get a higher temperature.

At this time, it depends on the strength of the soul purification liquid.

The villain in the Purple Mansion was still sitting cross-legged on the ground, slowly opening his small eyes, looking extremely cautious, his hands pinched his fingers slightly, and a soul power slowly left the Purple Mansion and flew towards the medicinal liquid in the Dan furnace.

When the soul power also enveloped the elixir, the villain pinched the finger again, and slowly used the soul power to separate the impurities in the elixir, and the quality of the elixir was determined by the impurities in the elixir.

Generally speaking, if you can't remove fifty percent of impurities, it basically means that this alchemy will not be successful.

Eliminate more than fifty percent and less than seventy percent of impurities, and after success, it is the next grade pill.

Eliminate more than seventy percent and less than eighty percent, and after success, it is a medium-grade pill.

Eliminate more than eighty percent and less than ninety percent and less than five, and after success, it is a high-grade pill.

And if you can remove more than ninety or five impurities, it is very likely to achieve the best elixir.

It's just that this requires a lot of soul strength and flexibility, and it can generally eliminate more than seventy percent and less than eighty percent, and can refine medium-grade pills, which already has a high status in the sect.

If more than eighty percent can be eliminated and a top-grade pill can be refined, I am afraid that the entire sect will respect this alchemist as a guest.

The higher the level of the elixir, the more difficult it is to remove the impurities, after a stick of incense, Zihong Qilian finally finished removing it, he only eliminated sixty percent of the impurities.

It's easy for him, too, but it's hard to keep removing impurities.
