"Master, is it difficult to set up the Yin-Yang Guixu Formation you mentioned?"

Ye Yang asked, a hint of urgency in his eyes.

He has also done some research on the Yin-Yang Guixu Formation since Gu Xuan mentioned it last time.

Guixu is also written as "Guixu". According to legend, it is a bottomless valley in the sea where all waters converge.

It is recorded in ancient books: Outside the East China Sea there is a big ravine called Guixu, into which all the water in the world and even the water in the entire Milky Way flows.

This formation integrates the five elements and eight trigrams. It not only contains the principle of the mutual conversion of yin and yang, but also contains the mystery of the interaction between yin and yang and feng shui between heaven and earth.

The name Guixu shows how lofty its intention was.

It’s just that it’s difficult to set up the formation, and it requires the purest yin and yang energies in the world to be successful.

"This formation is extremely powerful. Once it is activated, it requires 365 warrior-level cultivators to be deployed in various places to operate it. The amount of spirit stones consumed is also a number of days."

Ye Yang pondered for a moment. If the 365 warrior-level cultivators were included in the subordinate families and sects of Feitian Sect, the whole group could be made up.

Even relying solely on the current number of people in Feitianmen, it is impossible to gather so many monks.

Gu Xuan spoke again.

"I got this mountain protection formation by accident. If there weren't 365 warrior monks, 108 warrior monks working together could barely keep the formation running."

Ye Yang breathed a sigh of relief when he heard that.

One hundred and eight cultivators at the warrior level is a considerable number.

However, in comparison, it is not difficult for Feitianmen to gather enough.

"Nowadays, there are so many people in the sect, so it is not difficult to gather the strength of the entire sect to set it up. The real difficulty is that this formation covers the changes of the mutual integration of yin and yang, and the things needed for the center of the formation are extremely rare."

"The best ones among them are the Yin-Yang Dao Stone and the Yang-Yang Dao Stone. These two spiritual materials, one is extremely Yin and the other is extremely Yang. They are extremely rare in the world. If we want to set up this formation, we must first find these two spiritual materials."

"As far as I know, the most recent place where Yin-Yang Dao Stone appeared was deep in the Nether Mountain Range in southern Xinjiang. It is shrouded in fog all year round and is extremely dangerous. Only once in thousands of years will a piece of Yin-Yang Dao Stone appear."

"As for the Anode Dao Stone, it is hidden in the heart of the Flame Mountain in the Western Region. It is extremely hot there, with flames covering the sky. It is not easy to obtain it."

"In that case, can we buy it with Spiritual Stones?"

Hearing Ye Yang say this, Gu Xuan shook his head.

"These treasures are extremely valuable, and most of them are treasures that are not passed on to others. It would be very difficult to exchange them with ordinary spirit stones."

"I originally thought that the Yang Infant and Yin Infant born from the two gourds contained the Yin and Yang energy of heaven and earth, and that they complemented each other and could be used to set up formations. However, they took on new shapes and became babies like living creatures. If they were refined, it would certainly harm the harmony of nature."

In fact, the two babies were born from the essence of plants and trees, possessed special physiques, and possessed the qualifications of ancient powerful beings.

Whether it is the Solar Dao Body or the Taiyin Dao Body, the potential for cultivation is enormous.

Accept them as disciples and use them for the sect. No other consideration is given as long as they can break through to the realm of true person.

It is far more useful than refining a mountain protection formation.

There was a hint of loneliness in Gu Xuan's eyes, and it was obvious that he felt a little regretful.

After a pause, he seemed to have thought of something, and a hint of joy flashed in his eyes.

"Both the Southern Border and the Western Region are too far away. The situation is critical now. We don't know when the Netherworld and the countless monsters will attack us. It's not worth it to go there."

"However, apart from these two places, there should be another place where there is a treasure that can generate yin and yang, or vice versa."

Such twists and turns were somewhat unimaginable to Ye Yang.

“Don’t know where it is?”

Gu Xuan nodded, and his eyes became firm in an instant.
"Do you know the Black Mountain Demon?"

Ye Yang naturally knew that according to legend, there was a black mountain in the extreme north of Yalongling, which was shrouded in black fog all year round.

The Black Mountain is rich in Shoushan Xuanhuang, an excellent spiritual object for casting defensive formations and magical instruments.

It was also a good place in the minds of many independent cultivators before.

However, since then an old demon came and occupied the Black Mountain, he monopolized all the resources in the Black Mountain and never sold them to anyone else.

Even the Shoushan Xuanhuang used in the Five Elements Annihilation Cloud Formation was seized from the headquarters of the Red Lantern Society when Feitianmen later wiped out the group.

This old demon not only has unfathomable cultivation, but also controls many evil techniques. Even many masters dare not provoke him easily.

"The Black Mountain Old Demon..." Ye Yang murmured, with a hint of solemnity in his eyes.

"This person is secretive and ruthless. I have never heard of him leaving Black Mountain. However, once a foreign cultivator enters Black Mountain, it will be a bloody storm, and few can come out."

However, he reacted soon after.

Although the Black Mountain Old Demon is quite powerful, the Feitian Sect is also no less formidable nowadays.

He is no longer the A'mon of Wu.

It can be obtained through various means.

Moreover, the place where the Black Mountain Old Demon is located is not far from Feitian Gate.

There are also countless monsters and demons in the Black Mountain. This time, monsters are rioting in various places, and it is difficult to guarantee that there will be no problems anywhere.

If anything happens to attack Feitianmen in the future, it will still be a hidden danger.

In this case, it is better to take the initiative and clean it up first.

The two looked at each other. After years of cooperation, they could often know each other's inner thoughts with just a glance, so they made up their minds quickly.

Feitianmen announced a major event these days.

The first is to call on all the cultivators in the sect to eliminate the monsters. Any cultivator who kills the monsters within the influence of Feitianmen can go to Feitianmen to obtain corresponding rewards.

The second is that Feitian Sect will hold a disciple ascension conference one year later. The one thousand disciples recruited this time will be open to all eligible cultivators in the world, and the secret manuals of immortality will be taught to help them practice the supreme way.

This news has just been released.

This caused a huge uproar among the many monks.

"It seems that within this year, we will not only be busy dealing with the monsters, but also have to prepare well and strive to stand out in the Ascension Conference."

Many independent cultivators in Feitian Gate were discussing with each other, looking at the Feitian Gate hidden in the clouds in the distance, shining with colorful rainbow light, with determined eyes, and they all wanted to seize the opportunity.

“If I can achieve good results in the Ascension Conference and be accepted into the Feitian Sect, my life will be worthwhile!”

"It's strange. I don't know why, but during this period of time, these monsters have become very ferocious. They all seem to be desperate and have been attacking many small families and independent cultivators crazily."

"In this case, these monsters are a great opportunity for us. If we can stand out in the process of killing monsters and be noticed by Feitian Sect and become their disciple, we will make a fortune."

"Without further delay, we should unite and act quickly. The Feitian Sect released these two pieces of news together this time. I'm afraid it was also for this purpose. They want to select some truly good talents from the chaos caused by the monsters."

Soon, most of the cultivators within the Feitian Sect's sphere of influence were quickly mobilized.

Prepare to respond to the call of Feitianmen and go to various places to kill monsters.

And at the same time.

A huge spiritual ship slowly crossed the sky and shuttled through the clouds.

The huge body of the Tongtian Spirit Ship was carrying hundreds of elite disciples, breaking through the air. From towering mountains to deep canyons, the scenery along the way slowly unfolded like a picture scroll.

On both sides of the Tongtian Spirit Ship were two huge dragons, covered in lightning and thunder, about ten feet long, and they were traveling all the way, accompanied by wind and rain.

The purple scales were surrounded by dazzling electric sparks and emitted a deafening roar, which was awe-inspiring.

The spirit ship passed through layers of clouds and mist and finally arrived at a vast plain.

In the center of the plain stood a huge black mountain.

At this moment, the mountain was covered with black fog. There was no grass or trees on the mountain, and nothing could be seen clearly, but the thick fog covered the sky and the earth.

At first glance, it seems extremely weird and eerie, like a giant beast lying quietly in the center, emitting an unsettling aura, making it seem even more mysterious.

"Is this where the Black Mountain Demon is?"

On the Tongtian Spiritual Ship, Ye Yang stood at the bow and asked.

As soon as Ye Yang finished speaking, the entire Black Mountain began to tremble violently as if driven by some force.

The black fog rolled, and the originally blurred outline became more and more obvious.

At the same time, bursts of roars came from the depths of the Black Mountains. The sound was full of anger and mania, which was terrifying.

"Everyone get ready!"

As soon as Ye Yang gave an order, there were bursts of wind and thunder on the Tongtian Spirit Ship, the lightning dragon roared incessantly, and the colorful light of the magic spell instantly illuminated the dark sky.

However, he did not take action immediately.

The black fog ahead was still swirling. As the black fog continued to condense, a human face gradually appeared on the huge black mountain.

The outlines of his facial features gradually became clear, with a huge head, a stern face, eyes like lightning, and a powerful aura emanating from his whole body.

"Who are you? Why are you trespassing on my territory?"

The black-faced man's voice resounded through the sky, shocking everyone's hearts.

"This is where the Black Mountain Patriarch is. If you want to stay alive, leave quickly and don't provoke him."

"If not, I will definitely let you know how powerful our ancestor is!"

Before the voice faded, a dark vortex suddenly formed in the air, and several black rays of light shot out from it, heading straight for the spirit ship.

Seeing this, Ye Yang hadn't taken any action yet. Gu Xuanlue on the side waved his hand, and the eight-armed evil dragon's light of sin was activated, forming a transparent barrier around the spirit ship.

The black lights hit the barrier, making a deafening sound, but failed to penetrate at all.

The black face on the Black Mountain was silent for a moment, and then a sneer was heard.

"Interesting, it seems that the person I met this time is not an unknown person. Tell me your name, so that I can see who is so rampant here?"

Ye Yang took a step forward and replied in a deep voice,
"Excuse me, are you the Black Mountain Demon?"

"Black Mountain Old Demon? No one has mentioned this name for a long time. Others call me Black Mountain Old Ancestor."

"Who are you?"

"and many more"

The man seemed to have suddenly thought of something. Looking at the huge spiritual ship, his pupils contracted and a hint of nervousness appeared in his eyes.

"Could this be the Feitian Sect's Tongtian Spiritual Ship? Are you from the Feitian Sect?"

After saying this, a hint of human fear appeared on this huge face.

"good."

Ye Yang nodded.

"Hey, the Lord is here. I am the Black Mountain Demon, and I am definitely not an arrogant person. Why did you suddenly come to visit me in Black Mountain today? Could it be that you are Ye Yang, the master of both swords and knives?"

"It's that killer."

Halfway through his words, he hesitated and immediately changed the subject.

"What killer star? Look at my mouth. It turns out that I am a lucky star."

The Black Mountain Old Demon's voice was trembling, as if even the air had solidified a little.

"Fellow Daoist, Senior, I dare not call me an old demon in front of you. I am the Black Mountain Demon. I am by no means an arrogant and domineering person. I am actually a kind person."

"Why, you came to visit my Black Mountain today without informing me in advance? If I had known you were coming, I would have put on red makeup and welcomed you a hundred miles in advance."

Its face was already full of tears.

Ye Yang smiled slightly, walked slowly down from the spirit ship, and swept his eyes over the faces on the huge black mountain.

"You are too polite, Daoist. Since you have heard of my name, you must know that we at Feitian Sect have always acted in an upright manner, valued peace, and never made enemies without reason."

"I came here this time because I have something to trouble you, fellow Taoist."

After hearing this, the Black Mountain Demon's eyes behind the mask became even more frightened, but he still tried his best to calm himself.

I thought to myself.

"What do you mean by peace is precious? That's just your own excuse. This guy just entered the realm of a real person and he dared to kill Zhan Hongyi from the Haitian Chamber of Commerce."

'Then he took the Tongtian Spirit Ship and directly destroyed the Red Moon Mountain, destroying the Taoist sect. None of the three real people survived. Then he attacked the Dragon Taming Sect of the Dayun Dynasty and destroyed them. Together with the two demons, he killed the two generals of the Nisha Sect and forced the Holy Maiden Huangyuan to flee thousands of miles away.'

'Recently, together with the Jiutian Sect, they captured the killer Three-Eyed True Lord alive.
'Wherever he goes, he kills people and destroys sects, directly destroying the Taoist tradition. He is also very strong in both sword and knife cultivation. From today's perspective, my Black Mountain is in danger.'

When I think about it this way, I don’t know why.

There was a sudden sense of horror coming from the Black Mountain, and the mountain began to tremble in fear.

"Your Excellency is too kind. I have always respected Feitian Sect. If there is anything I can do for you, please let me know."

"very good."

Ye Yang and Gu Xuan looked at each other, nodded, and their tone calmed down.

"To be honest, we came here to look for the Anode Dao Stone and the Cathode Dao Stone. We heard that you have these treasures, so we wanted to ask if we could borrow them temporarily."

"hiss!"

Hearing this, Black Mountain felt a pang of heartache.

This is a treasure that he treasures.

He also knew that it was called a loan but in fact it was given for free, but seeing that the other party was coming with such a strong momentum today, he could not refuse no matter what.

Otherwise, I am afraid that Black Mountain will disappear into the world just like the Red Moon Sect and the Dragon Controlling Sect.

"Easy to say, easy to say."

The man on the Black Mountain's face changed slightly, and a faint green light shone from his deep eye sockets.

But the light flickered.

At this moment, he was obviously feeling extremely uneasy.

"The patriarch is here. It's not that I don't want to give them up, but the positive pole Dao Stone and the negative pole Dao Stone are not ordinary things. They contain the purest yin and yang power in the world. Even if ordinary cultivators get them, they can't control them."

The Black Mountain Demon's voice was deep and powerful.

"I don't know what the sect needs these things for. Moreover, if these two stones fall into the hands of unscrupulous people, it may cause unpredictable disasters."

There was still a hint of evasion in his words.

Ye Yang and Gu Xuan looked at each other, looked at the Black Mountain Old Demon, and then spoke.

"This is not something you should think about."

"As for how to use these two stones, we have made proper arrangements, so don't worry."

"Well, since the Lord has said so, I am willing to contribute to him."

Ye Yang and Gu Xuan looked at each other. They both didn't expect that the Black Mountain Old Demon would be so easy to talk to.

It is rumored in the cultivation world that the Black Mountain Old Demon is an unrivaled old demon, vicious and stubborn, cruel and ruthless, and he alone controls the production of Xuanshan Shouhuang.

Few people who go against him can survive.

Now it seems that this rumor is not entirely true.

But soon.

They then figured out the key to the matter. It was true that the Black Mountain Demon was vicious, but it depended on who he was targeting.

The Feitian Gate of today is no longer what it used to be. Even such a notorious old demon does not dare to act presumptuously under the Feitian Gate's spirit ship.

"Please follow me, Master. It's not easy for you to come here. I have already prepared some light wine and tea. I hope you can come and sit down."

The voice of the Black Mountain Demon sounded again, and this time it seemed to sound more sincere.

Following the guidance of the Black Mountain Old Demon, the two men got off the spirit ship and passed through a dense forest. Suddenly, the view in front of them opened up. They saw an exquisite pavilion sitting on a green lawn on the bare Black Mountain.

The surrounding area is filled with various exotic flowers and plants, emitting bursts of fragrance.

In the pavilion, the Black Mountain Old Demon had been waiting for a long time. He waved his hand and motioned for the two to take a seat. Then several maids brought fragrant tea and delicacies.

Ye Yang had heard before that the true form of the Black Mountain Demon was a huge rock located at the border of the cultivation world and the underworld.

Later, after being washed by the water of the Yellow Spring for countless years, he was born with intelligence and became a giant.

The Black Mountain Old Demon did not show his true form, but appeared as a wooden puppet wearing a black robe, sitting on the ground with Ye Yang and others.

"My two Taoist friends, please look, this is what you call the positive pole Dao stone and the negative pole Dao stone."

After he finished speaking, he stretched out his hand and the ground shook. After a while, two stones, one white and one black, grew out of the ground.

White stone is as smooth as jade, as if it can dispel the haze around it; black stone is steady and heavy, giving people an indescribable sense of security.

There seems to be an invisible force between the two stones that attract each other, yet they maintain a subtle distance.

The flow of energy between each other forms a peculiar balance.

"These are the Yin and Yang stones. They were just two stone embryos when I accidentally obtained them. They have been in my hands for a thousand years. After that, I brought them to the center of the Black Mountain to cultivate them. They absorbed the essence of heaven and earth, and then they took shape."
