Three days later, in a col somewhere near the Western Wilderness, Wei Wuxian sat cross-legged in a dry cave, just now he had just finished warming the flame bird that was resting on his chest.

The eggs are only the size of chickens, and they are not in the way when they are placed in their arms, and he has to use his heart fire to warm them once every morning, noon and evening, and he has not been interrupted since he came out of Snake Mountain.

It was less than a mile away from the Ten Thousand Ghost Caves, and even in the middle of the day, he could see that the sky in the distance was black and gray, which was the reason why the earth's evil yin qi was extremely strong.

He didn't rush over there, just when he was warming the Yan Sparrow eggs before, two people passed by the cave where he was hiding, and they saw that they were monks from the Xuanyue Sect.

The 'ghost control technique' he got was in the hands of Xia Min, a true disciple of the Xuanyue Sect, during the Tianshui Sect's Hundred Fruit Festival, not only the Xuanyue Sect, but also the true disciples of several major sects in the Central Plains had suffered under him, and it could be said that he had lost face, and the people of these sects would not be kind to him.

It is normal for the people of the Xuanyue Sect to come to the Ten Thousand Ghost Cave, what they practice is the art of yin ghosts, and the two monks of the Xuanyue Sect are both cultivators of the ninth layer of the Qi refining period, and there is no danger to him, but when they passed by, they said that they had asked a senior to come over, and that senior must be a monk of the foundation building period, so I don't know if it is a monk of the Xuanyue Sect or a monk from another sect.

Wei Wuxian waited for the two of them to leave for a while, and followed curiously, with his cultivation as a guide, the two of them in front of him didn't know that someone was following them, and they talked about things to themselves.

"Senior Brother Yan, you said that after that senior achieved his goal this time, he promised to give us something and wouldn't repay the debt, right?"

Senior Brother Yan on the side made a silent gesture, and then glanced around before saying, "Senior Brother Zeng, you are too reckless, how dare you say such things casually outside, if you let that senior know, you and I can't afford to be guilty." ”

Senior Brother Zeng glanced left and right and said, "There is no one in these four places, what are you and my senior brother afraid of?"

Senior Brother Yan said: "Be cautious, you must know that trouble comes from the mouth, Senior Brother Huang just said something behind his back that shouldn't be said, and you don't know what will happen now." ”

"Alright, I got it. It's still early, and that senior must not have come yet, so let's go down there and wait here. Senior Brother Zeng looked at a cave not far away that was only a dozen zhang wide.

"Let's just look for something on the side, don't let the small be lost. ”

"Well, there's been a lot of people in this area, there's nothing good about it. ”

The two walked towards the giant cave as they spoke, looking for some local specialty materials in the surrounding area.

Wei Wuxian probably understood the other party's intentions, so he ignored the two of them and quietly entered the Ten Thousand Ghost Cave from the other side.

The entrance to the Ten Thousand Ghost Caves is not large, but the bottom is extremely large, the terrain is extremely complex, and countless passages are connected like spider webs to build a strange world independent of the outside.

Wei Wuxian didn't dare to be careless, and found a path down at random, and there were wandering spirits everywhere along the way, these spirits had no intelligence, and they were wandering and looking for food in it.

The food of the geist is the remnant soul and the yin qi in the cave, the remnant soul can make them strengthen the divine soul, and the yin evil qi can nourish the divine soul. However, they prefer to devour remnants more than the sinister spirits. The speed at which the Yin Qi nourishes the Divine Soul is relatively slow, not as fast as the Devouring Remnant Soul.

If ordinary people fall inside, they will rely on their natural ability to sense the soul of the god to burrow into the human body and devour the soul hidden inside, and there will also be a war between them, devouring each other in order to become stronger, and this is how the yin ghost is formed.

Yin ghosts are low-level ghosts after the geist opens up their spiritual intelligence, and they also rely on devouring geys and absorbing yin evil qi to enhance their own strength, so you will hardly see two Yin ghosts of unequal strength staying together, they will both hide from being discovered by their more powerful kind.

There are many yin things in the Ten Thousand Ghost Caves, and they are also very scattered, and no one knows where they came from or why they have not been exhausted for thousands of years. Some people say that there is another world connected below, which is the world of ghosts, but this has not been confirmed, because the yin and evil aura below is so strong that even the Jindan monks dare not set foot in it.

Wei Wuxian only moved within a depth of about fifty zhang above, and the publisher of this mission had explained that the Yin Soul Stone would generally appear at this depth, and of course, the further down, the more and better the quantity and quality of the Yin Soul Stone.

However, the task publisher clearly pointed out that it is best for monks to move within 50 zhang at the beginning of the foundation building period, monks can go down another 50 zhang in the middle of foundation building, and in the later stage of foundation building, they can reach the deepest place of 150 zhang to find the Yin Soul Stone.

He is a cautious person, it is better to put a little more effort on it than to take risks, the depth of thirty zhang is just right, not to mention that he has something that others don't have to help, that is, the 'Soul Eater Beast'.

From the moment he entered the Ten Thousand Ghost Cave, the Soul Eater Beast in the Soul Bottle on his body sent out a strong will to think of it.

Wei Wuxian didn't let it out for the time being, and first searched for it below, the Yin Soul Stone was a crystalline body condensed by the condensation of the remnant soul and the Yin Evil Qi, indicating that it was black and brown, different in size, and the spar structure contained an extremely strong Yin and Evil Qi, which was the best material for refining the Horcrux, and the Soul Bell in his storage bag was made of the Yin Soul Stone as the main material.

After searching for about an hour, he found a ghost stone the size of a thumb cover, and the weight was about two dollars, and to complete the task of ten catties, he had to find five hundred materials of this size, no wonder the task publisher would mark the reward of one thousand merit points, according to the current situation, it is not possible to collect the required clinker in a place fifty zhang deep, these places have been searched countless times, leaving only some scattered small pieces of materials.

There are more Yin Soul Stones below than above, but you need to take a lot of risks to go down, which is the main reason for the high merit reward.

Wei Wuxian stopped looking, took out the soul bottle, opened the ban and released the soul devouring beast.

This guy came out of it looking very excited, and circled around, and was actually caught by it and swallowed by seven or eight geismos.

Wei Wuxian summoned it to his face, pointed to the Yin Soul Stone in his hand and said a few words, and then the Soul Eater turned into a cloud of black smoke and disappeared at the end of the passage.

Wei Wuxian waited in place with peace of mind, and pondered the 'ghost control technique' when he had nothing to do.

The ghost art is the secret of the Xuanyue Sect, and through this method, the hundred ghosts can be used to serve their lives, and the end is extremely mysterious.

What's even more valuable is that in addition to the method of envoy hundred ghosts, there is also a method of refining soul silk. The aura of Ruijin that he has condensed has played a wonderful role in many battles, and the Soul Thread is not inferior to the Soul Silk, and it is a more distinctive weapon, since he has obtained this refining method, of course he wants to condense the Soul Thread and use it as a killer weapon against the enemy.

Both techniques are extremely mysterious, and it took a lot of effort before and after he could understand it thoroughly, and now he is in the Ten Thousand Ghost Cave, which can just be verified whether it is correct.

His eyes were slightly closed, and he stared ahead, sensing through his divine sense that a yin ghost was hovering nearby.

This Yin Ghost couldn't see through the depth of his cultivation, so he didn't dare to get too close to the ground, and he was always in danger in the Ten Thousand Ghost Cave, and since it had not turned on its spiritual wisdom at that time, it was born to know how to hide itself from being devoured by its own kind or other creatures.

However, it never expected that its every move was under Wei Wuxian's nose, and the reason why it didn't move it was because it didn't find a suitable opportunity.

His hands were like wheels to spell out one spell after another, and immediately the yin wind in front of him agitated, and the yin ghost who was snooping in the distance only felt a huge suction force pulling it towards the person, and his heart immediately panicked, struggling to get rid of this suction, but how could it resist the spell of a foundation building period monk with its strength, and was instantly attracted to Wei Wuxian's front, and his whole body was already uncontrollable, stiff and frozen in place.

Wei Wuxian succeeded in casting the spell for the first time, and he was also happy in his heart, he looked at the yin ghost in front of him, and found that it was formed by a cloud of gray energy, and the appearance of a person, his facial features and everything were very blurred.

"You can understand what I'm saying!"

He tried to communicate with the ghost.

The ghost nodded with difficulty.

"Very well, it seems that you are a ghost who is more aware of current affairs. Wei Wuxian quipped, then stretched out two fingers and said, "Two choices, one is to serve me from now on, I will do whatever I ask you to do, without the slightest violation, and the other is to throw my Soul Eater Beast as a snack, presumably it should be happy." ”

The one who had just arrived and hadn't seen the Soul Eater Beast, otherwise he wouldn't have dared to stay where he was and snoop, and he would have been scared away. However, it could understand the meaning of Wei Wuxian's words, as a ghost, there was never any dignity to speak of, and survival was their biggest and only choice.

So it quickly nodded and agreed to become Wei Wuxian's ghost slave, swearing allegiance to this new master, who seemed to be unusually powerful.

Wei Wuxian said: "Very good, your choice is very wise, but just in case, I need you to sign the ghost contract, if you dare to break the oath, then you will immediately be scattered, and you can't even do the ghost."

After that, he opened his mouth and spewed out a ball of essence, and then tore a ball of divine soul on the yin ghost's body, mixed together, and turned into a palm-sized black paper, and a golden rune appeared on one of his words every year.

"Put a mudra on it!"

With a flick of his fingers, the page full of runes floated to the Yin Ghost.

The Yin Ghost was completely stunned now, and it wasn't until Wei Wuxian spoke that he realized what he was going to do.

As soon as its hand landed on it, the ghost contract seemed to come alive, twisting into a slender black line and burrowing into the Yin Ghost's fingers.

The Yin Ghost's whole body trembled, his eyes flashed with golden light, and he had established an indescribable connection with Wei Wuxian, so he also felt his terror and strength even more, and bowed humbly and said, "The ghost slave Ah Cai has seen the master. ”

"Okay, this name is good, it's a good luck!" Wei Wuxian nodded with satisfaction, this little yin ghost is a little weak, but it is still quite well-behaved.

At this moment, suddenly the Yin Ghost Ah Cai on the opposite side trembled like a sifting chaff, but his legs couldn't take a step anyway.

Wei Wuxian turned to look, only to see a black smoke coming from that side, and when it came closer, it condensed into a ball, and it turned out to be the Soul Eater Beast coming back.

The Soul Eater saw the Yin Ghost Ah Cai at first sight, and it was born to devour Yin Things, and it immediately suppressed the Yin Ghost with coercion and prevented it from escaping.

"Don't touch it, he's my ghost slave!" Wei Wuxian relieved the pressure from the Soul Eater for the Yin Ghost Ah Cai, and although the Soul Eater was a little reluctant, it still ran to him very obediently, and then spit out a bunch of Yin Soul Stones from its mouth.

Wei Wuxian took a cursory look, there were at least two or three catties in front of him, and this was a lot of effort, and the Soul Eater Beast had brought him such a big surprise, he smiled and put them into the storage bag, looked at the Soul Eater Beast with a bitter face, hesitated, and took out some of it and threw it to it.

The Soul Eater immediately showed an anthropomorphic smile on its face, and sucked them all into its stomach in one gulp, burping comfortably, but when it saw the Yin Ghost Ah Cai on the side, it showed a posture of swallowing saliva and grinding its teeth from time to time, which made the lovely Yin Ghost Ah Cai have a split liver (if any), and he didn't dare to look at the monster in front of him.

Wei Wuxian said: "These are not enough, is there anything else below?"

The Soul Eater couldn't speak, but through his mental sense, he understood what it meant, and it had gone down to a hundred zhang deep before, and there were many of them, but there were many of them that even it feared, and they didn't dare to stay down for a long time.

Wei Wuxian secretly laughed to himself, this guy also knows that he is afraid? He has not studied the Soul Eater Beast, but the current strength of the Soul Eater Beast is equivalent to the existence of white eyes and black demons, and there will be gray eyes and black demons in a hundred zhang deep below, which is equivalent to the existence of a monk in the middle stage of foundation building, and it is not something it can deal with.

Yin ghost Ah Cai spoke at this time: "Does the master want this crystal?"

Wei Wuxian's eyes lit up, this guy is a native of this place, how could he forget it.

"You know where it is?"

"There are a lot of things not far from here, and we can't devour them directly, but there was once a human monk like the master who came here and brought a lot of them from below, and the people died, and the things were left there.

Wei Wuxian didn't expect such a thing, and said, "Is there a danger over there?"

"Nope. ”

"Alright, you can take us over there. ”

His interest has increased greatly, and the monk who can go down to a deeper place is definitely not an ordinary person, you must know that because of the strong yin and evil aura here, the temperature is quite low, and with his strength, he can reach a place at most one hundred and fifty deep, and then go down without anything else to do it, and he will be frozen by the yin and evil qi.

The Yin Ghost Ah Cai led the way in front, and he and the Soul Eater followed behind, and the combination of a ghost, a beast and a person walked through the thousands of passages under the Ten Thousand Ghost Cave.

Wei Wuxian felt that the concept of 'not far away' that the yin ghost Ah Cai said had to be repositioned.

They had been walking down for an hour before they came to the location it said it was, in front of a huge cavern.

There was water here, black water, and there was no ice on it, and you could vaguely see something swimming inside.

The Yin Ghost Ah Cai was just about to speak, but was grabbed by Wei Wuxian and put into the soul bottle along with the Soul Eater Beast.

In the cave opposite, there were three people who seemed to be arranging magic circles, and two of them he had seen were the two Qi Refining Stage cultivators of the Xuanyue Sect before. The other person is a fresh face, but the other party's cultivation can be seen at a glance, and he is a monk in the middle stage of foundation building.

The three of them were engrossed in setting up the magic circle, and they didn't notice that anyone was nearby.

The mid-foundation monk looked to be in his forties, with a thick beard and a very decent appearance.

The clothes on his body are also the Taoist clothes of the Xuanyue Sect, and at this time he is planting a formation flag on the ground, there are forty-nine such array flags, and this is the last one.

There was a moonstone on each side of the cave, so Wei Wuxian could see the situation inside very clearly. According to the array flag currently arranged by the other party, it turned out to be the 'Soul Devouring Array'!

Wei Wuxian was very puzzled, how could this Xuanyue Sect's foundation-building cultivator understand the 'Soul Devouring Array' of the Fallen Soul Sect? Also, who was he arranging the 'Soul Devouring Array' here for? All kinds of suspicious things made him unable to understand.

The two Qi Refining Stage monks walked up to the mid-foundation building stage monk and said, "Senior, we have already finished the things you have explained, you see, we can leave first now." ”

The mid-foundation building monk smiled and said, "Don't worry, I'll talk about it when that guy comes." I need your help here. ”

The senior brother said, "Didn't the senior say that as long as we help you finish arranging the magic circle?"

A smile froze on the face of the mid-foundation building monk: "What, don't you want to help me?"

Senior Brother Yan was so frightened that he hurriedly stepped forward and waved his hand: "No, Senior Brother Zeng doesn't mean that, we just do everything according to the instructions of our predecessors." After that, he turned his head and glanced at his junior brother.

Senior Brother Zeng was not a stupid person, so he said helplessly: "The younger generation should follow the instructions of the seniors." ”

"Don't worry, what I said before will be given to you after this is done, if not more. The sharp-beaked monkey-cheeked mid-foundation monk laughed.

The men took off the moonstones that had been placed around them and hid in the darkness.

Time passed slowly, and before I knew it, half a day had passed. Just as Wei Wuxian was considering whether to continue waiting, the yin wind around him suddenly became fierce, and there was a ghostly roar from the surrounding passages, and Wei Wuxian inexplicably felt an unspeakable crisis coming from the opposite side.

He was ready to meet the enemy, but a gust of wind passed by the opposite side and swooped directly into the cave in front of him.

Immediately there were bursts of roars in the cave, and several rays of light flashed, and he saw a monster that looked like a human but not a human, a ghost and not a ghost appeared inside.

At this time, the mid-foundation building monk also came out, and smiled at the monster: "Xu Yinghua, you finally can't help but come out of it, this time I will see how you escaped from the palm of my hand!"

The monster known as Xu Yinghua said loudly: "Liu Peide, you are a beast-faced thing, if you don't come to me, I will also go to the Fallen Soul Sect to find you." ”

"Just by you, you are the one who has cultivated the 'Yin Soul Dafa', what can you do with me, in the Falling Soul Sect, I am the son-in-law of the sect master, the personal disciple of the Great Elder, no matter how much you toss, you can't make much waves. Also, I'm tired of playing with your woman, and now I've made a good pair of yin corpse puppets; by the way, you should have also received a piece of her skin, and your name is still embroidered on it! I will kill you again today to make a pair of yin and yang corpses, how about it, you should be very happy and excited to hear it!"

Liu Peide laughed, and his words revealed extremely despicable humiliation.

Not to mention the 'monster' known as Xu Yinghua, even Wei Wuxian, who was spying outside, couldn't help but go up and slap Liu Peide a few times.

"You..." Xu Yinghua was so angry by Liu Peide's words that he couldn't speak, he had hidden for many years, just so that he could one day get his beloved wife back, but now that his beloved wife is dead, and he has been made into a yin corpse by the other party, the hatred in his heart has reached the extreme, and he can't care about it, so he rushes directly to the enemy opposite.

Wei Wuxian knew that this guy would definitely fall for Liu Peide's tricks, but if he were himself, I'm afraid it would be the same! He didn't rush to point it out, the situation was unclear, and he still needed to wait and see what happened.
