Immediately afterwards, this Steward Liu introduced several secret techniques to Pang Yu one after another, but none of them entered the eyes of Yu Yu.

Hearing the end, Yan Yu became a little impatient, and felt that he was wasting his time, so he deliberately wanted to leave.

Seeing this, Steward Liu also understood it completely. The two monks in front of them definitely didn't want these secret techniques, after all, these two people were already great cultivators in the realm of the Yuan Infant Stage, and the secret techniques they said naturally couldn't impress them, so they said that they would keep the two of them.

"Two seniors, it seems that the secret technique introduced by the juniors just now must not be in the eyes of the two seniors. It seems that if you don't take out the things that are pressed by the treasure box, you won't be tempted by the two seniors......

However, according to the rules, this secret technique is quite special, if the two seniors are interested in listening to it, they need to pay some spirit stones first, and no matter whether they buy it in the end or not, they will not return it......"

Hearing this, Yan Yu became interested, and an expectant expression appeared on his face.

Especially this secret technique that can only be known by paying first, in the eyes of Yu Yu, it must be a good secret technique, and he naturally wants to listen to it.

Immediately, he said very happily, "No problem, how many spirit stones?"

Hearing Yan Yu's words, seeing his expression, Steward Liu smiled slowly and said, "Two seniors, this secret technique is actually a set of magic skills, so it requires a hundred high-grade spirit stones......"

Regarding the origin of this secret technique, this Steward Liu did not hide it, and said it calmly.

Seeing that Yan Yu nodded secretly, he was not surprised by the origin of this secret technique, and with a light tap of his jade hand on the storage bag, he took out a thousand intermediate spirit stones from it, and threw them to this Liu steward without hesitation.

Steward Liu took the spirit stone, the smile on his face was even better, and he thought in his heart, "These hundred high-grade spirit stones are taken out without blinking their eyes, they must be a rich master, it must be a descendant elder of the Immortal Cultivation Family", and immediately slowly stated.

"Two seniors, this set of magic skills is actually the "Nine Heavens Demon Skill" created by the Nine Heavens Holy Lord who was destroyed by a decent monk thousands of years ago.

This set of magic skills is more cruel to cultivate. Every time you kill someone, you use magic skills to collect the three souls and seven spirits of the person you killed, and then use these three souls and seven spirits to continuously nourish the magic skills. After practicing this set of magic skills, a blood-colored vortex will appear behind you, and ghosts will haunt it to help kill enemies.

Once this blood-colored vortex is cultivated, it should not be underestimated! The blood-colored vortex behind the notorious Nine Heavens Holy Lord back then was not only infested with ghosts, but also disturbed the minds of the surrounding monks......

The ghosts that haunt this whirlpool are the three souls and seven spirits of the people killed by cultivating this set of magic skills. The more people you kill, the stronger the people you kill, and the more powerful these ghosts will be......

However, once these souls are absorbed, they will not enter reincarnation, and they will not be able to transcend the ...... forever."

Yu listened tirelessly to Steward Liu's introduction of this set of "Nine Heavens Demon Skills", and couldn't help but feel a little interested in it. Although this "Nine Heavens Demon Skill" is cruel, it is inevitable that some people will be killed on the road of cultivating immortals, and if the souls of these people are used reasonably, it is also a good thing.

The Sixth Generation, who was learning the languages of various ethnic groups beside him, suddenly opened his eyes, and a faint smile appeared on his gloomy face. With his study these days, he has already mastered the common language on the Mingsu Xingchen, and he naturally listens to the "Nine Heavens Demon Skill" in the mouth of Steward Liu.

"How many spirit stones?" the Sixth Boy asked uncontrollably when he heard half of it.

"Back to the seniors, 10,000 high-grade spirit stones......" Steward Liu saw that the little boy finally spoke, so he said without thinking.

As soon as these words came out, the faces of the sixth-generation boy and Yan Yu became ugly, and the price of these 10,000 high-grade spirit stones was indeed a bit outrageous......

And there are not so many spirit stones on the two of them......

Although this "Nine Heavens Demon Skill" rain is interested, it is not necessary. After all, the method of his major cultivation is "Taishang Forgetting the Dao", and it is not impossible to cultivate another method, but it takes a long time not to mention, if the two methods are not integrated, there will be a conflict and the gains will outweigh the losses......

However, the sixth boy attaches great importance to this "Nine Heavens Demon Skill", and he is now lacking a major law decision, and he feels that this set of "Nine Heavens Demon Skill" is tailor-made for himself.

Although the Sixth Boy doesn't know who this Nine Heavens Holy Lord is and what magical powers he has, he can also guess that he is a monk in the Transformation Period from the mouth of this Steward Liu, which shows that this "Nine Heavens Demon Skill" is also a set of magic techniques that can be cultivated to the Transformation Stage, which is what the Sixth Boy lacks the most now!

The expressions on the faces of Yan Yu and the Sixth Boy, this Steward Liu naturally saw it in his eyes, and immediately spoke.

"Two seniors, the prestige of this "Nine Heavens Demon Skill", presumably the two seniors also know it. And the notoriety of this Nine Heavens Holy Lord came from this set of secret techniques......

Back then, in order to kill the Nine Heavens Holy Lord, even the great monks of the infant transformation period took action, but you can imagine the power of this set of magic skills......

And in today's immortal cultivation world, it is impossible for this set of magic skills to be handed down at all, if the outside world knows that we have the "Nine Heavens Demon Skill" here, I am afraid it will be difficult to gain a foothold in this place in the future......

So the price is really not high......"

The prestige of the Nine Heavens Holy Lord and the "Nine Heavens Demon Skill", Li Yu and the Sixth World Boy naturally didn't know, but they didn't dare to ask about these things directly, so as not to expose their identities.

Yu Yu was slightly stunned, and the sixth boy exchanged sounds.

"Sixth, what do you think of this set of magic skills?"

"Master, the sixth generation thinks it's very good. From this kid's mouth, it should be a good set of tricks. What does it matter if you have magic skills or not, as long as you can increase your strength......"

"Sixth, how many spirit stones do you still have?"

"Master, I don't have many spirit stones on me......"

After some discussion between the two, the final decision was made between Yu Yu and the Sixth Boy. Let's bargain with this Steward Liu first, after all, he is in a strange place now, and he doesn't know the true strength of this "Rebellion against the Sky". If the bargain fails, the two decided to ask about the whereabouts of this set of magic skills, and they took it directly......

Anyway, in the end, the two of them are going to the "Wuji Immortal Mansion", and I am afraid that they will come to this "Mingwei City" again in the future......

After Steward Liu waited for a long time, Yan Yu said lightly, "Steward Liu, the two of us are very interested in the "Nine Heavens Demon Skill" you said, but we can't rely on your words, and the two of us will completely believe you.

You still take out this "Nine Heavens Demon Skill", let's verify the authenticity, you think it's good......"

Steward Liu sat opposite Yan Yu and the Sixth Boy, with a hesitant expression on his face. But after some struggle, I nodded and agreed.

"Two seniors, you wait here for a while, and the juniors will go and get it. With that, Steward Liu said goodbye to the two of them, turned around and walked towards the corner of the hall.

As he approached the corner, the secret door in the corner suddenly opened, and he stepped in.

Yan Yu took a sip of the spiritual tea in his hand, and glanced at the sixth boy, but neither of them spoke.

It took a long stick of incense before this Steward Liu walked out of the secret door. At this time, there was already an extra black wooden box in his hand, and there was still some dust on it, which had not been wiped off.

Nodding at Yu Yu and the Sixth Boy, Steward Liu sat in front of the two, carefully took out a red jade slip from the black wooden box, and slowly handed it to them. And said, "Two seniors, please look at the two of you." ”

Yu Yu's eyes narrowed slightly, took the jade slip, and began to check it inside.

And the sixth boy sat aside, full of anticipation, and his little eyes began to pay attention to the direction of this secret door, and his heart began to have crooked thoughts.

After a long while, Yan Yu retracted his senses, and there was no expression on his face, so he casually threw the red jade slip to the sixth boy.

There is indeed a set of magic techniques called "Nine Heavens Demon Skill" in this red jade slip, but there is a prohibition that blocks the divine sense......

Only a small part of the first part of this set of spells can be seen, and the rest are blocked by this prohibition.

Yan Yu had just tried to crack the forbidden technique inside, but in the end, he found that if there was no correct way to open it, once he tried to crack it, I am afraid that everything recorded in this jade slip would disappear in an instant and could not be restored......

After understanding this, Yan Yu finally understood why this Steward Liu dared to take out this "Nine Heavens Demon Skill" to identify the authenticity of the two of them.

I'm afraid that the idea of snatching it won't work......

After a while, the sixth-generation boy looked at this Liu Steward with a gloomy expression, and he naturally discovered the prohibition in this jade slip.

"Steward Liu, let's get straight to the point. 10,000 high-grade spirit stones, we naturally don't have them. Do you want to see if it's cheaper?" asked Yu Yu.

"Two seniors, this 'Nine Heavens Demon Skill' is worth the price of 10,000 high-grade spirit stones, it can't be cheaper......" Steward Liu waved his hand and replied embarrassedly.

Yan Yu's expression changed, and he said with some seriousness, "Steward Liu, let me do some of it, but the two of us sincerely want to buy this "Nine Heavens Demon Skill"!"

Steward Liu snorted, and said helplessly, "Two seniors, there really can't be less, and my little steward can't do this master......"

At this moment, the sixth generation boy lost his patience, and the great monk of the late Yuan Infant Realm and the little Jindan monk in the late stage of the red-clothed beast and the little Jindan stage monk in Steward Liu said so much!

The whole body cultivation of the sixth generation boy exploded in an instant, and the moment the realm cultivation of the late Yuan Infant unfolded, this Steward Liu was shaken off the seat and fell to the ground.

And the wooden chair that Steward Liu was sitting on under him was directly shattered and turned into dust.

A trace of blood flowed from the corner of Steward Liu's mouth, and he saw him wipe it casually, and said with a smile, "What do you have to say before you seniors, we have to be reasonable......"

When the sixth boy heard his words, he was directly stunned, and his face became even more difficult to look at. I thought to myself, "What else do I have to reason with you?"

Seeing that this Liu steward did not have a seizure, Yan Yu picked up the teacup and said in an unquestionable tone, "A thousand high-grade spirit stones, that's all!"

Steward Liu stood up, patted the dust on his body, and hurriedly replied, "No, no, no, 10,000 high-grade spirit stones......"

Yan Yu's face changed slightly, and he said, "Two thousand high-grade spirit stones!"

"No, no, 10,000 high-grade spirit stones!" Steward Liu had already taken a few steps back at this time, but he still refused to give in to the price......

"Okay then...... Five thousand high-grade spirit stones, so be it!" After a moment of silence, Yu Yu said with some embarrassment.

"Two seniors, we are reasonable, the juniors can't be the masters, so they can only be 10,000 high-grade spirit stones......"

Yan Yu sat on the wooden chair, his face becoming more and more gloomy and ugly. No matter how she thought about it, she didn't expect that this Liu steward would not let a spirit stone go, which really made her feel incredible......
