In the alchemy hall in the Si Dan Palace, there are nearly one alchemy furnace of all sizes, among which the Dan furnace in the center is the largest and the most precious.

The alchemy furnace in the center of the alchemy hall is connected to the Heaven and Earth Yuan Fire below the Si Dan Palace, which is a flame that can only be condensed by a strong person who surpasses the existence of the Holy Soul Realm, and the pill refined with such a flame is even more outstanding.

Near this largest alchemy furnace, there are also layers of shining light curtains, Cheng Yun rode the demon ritual, has come to the alchemy hall, after he saw this layer of light curtain, he shook his head slightly, he has already probed other Dan furnaces with his divine sense, there is no Ji Yan Dan, the last hope is in this largest alchemy furnace, he then turned into nothingness with the demon ritual, and slowly passed through this layer of light curtain.

"Enlightenment!"

Cheng Yun punched out a seal, and after inputting spiritual power, he opened the seal of this alchemy furnace and explored it with his divine sense.

In this alchemy furnace, there were four or five rays of light, and Cheng Yun's divine sense went deep into it and checked those four or five rays of light.

"Ji Yan Dan! This is Ji Yan Dan!" Cheng Yun saw one of the rays of light, and his divine sense detected Yan Yan's breath, and what came out of this breath was an elixir that looked the same as the Ji Yan Pill described by the old man of the Immortal.

Cheng Yun swung out a spiritual power to approach this Jiyan Pill, but found that this was not a finished pill, but a semi-finished product that was still to be refined.

Taking this half-finished elixir, Cheng Yun re-sealed the seal, and at this moment he heard a voice calling for help.

"Help me, help me!"

The voice, eager and faint, came from the alchemy furnace.

"In the alchemy furnace. There are still living creatures?!" Cheng Yun was shocked in his heart, the voice that came out was obviously a living creature, what kind of creature would be able to survive after such a long time.

"The fire here is the Heaven and Earth Yuan Fire! Only the monks who have surpassed the Holy Soul Realm can condense it, and only the monks who have surpassed the Holy Soul Realm can resist it! In this alchemy furnace, there are living beings. In other words, the creatures in this alchemy furnace will be able to rival the powerhouses that surpass the existence of the Holy Soul Realm!" Cheng Yun thought of this, and his heart was shocked again, and he immediately looked at this alchemy furnace vigilantly.

"Help me" The voice calling for help sounded again, and Cheng Yun listened carefully, trying to distinguish where the voice came from.

"Who are you!?" Cheng Yun couldn't find the source of the voice, so he could only ask out loud towards the alchemy furnace.

"Help me, save me, I'm the Spirit Fire Demon Venerable! Help me open the alchemy furnace! I can give you everything you want!Help me!" Seeing someone respond, the strong man in the alchemy furnace who claimed to be the Spirit Fire Demon Venerable quickly replied to Cheng Yun.

"Spirit Fire Demon Venerable!?" Cheng Yun heard the name. Showing a solemn look, two points can be inferred from this name, first, the creature in the alchemy furnace is a member of the demon clan, and second, his cultivation. It's His Holiness or even above!

"He asked me for help, that is, he relied on his own power. I can't come out, my safety, don't worry about it for the time being!" Although Cheng Yun was shocked, he did not lose his mind, he knew that the Spirit Fire Demon Venerable had a request for him. It shows that he is in a very difficult situation now, and he has no power to threaten himself, as long as he is a little cautious, Cheng Yun will not be in danger.

Cheng Yun didn't make a sound, he quietly looked at the alchemy furnace. looked at the Jiyan Pill in his hand again, and did not answer the words of the Spirit Fire Demon Venerable.

"This Jiyan Pill is already a semi-finished product, just need to refine it, it can become a finished pill! I haven't learned the art of alchemy, even if I open this alchemy furnace, I can't finish refining the Jiyan Pill, if I open the alchemy furnace without authorization, I'm afraid that I will release the Spirit Fire Demon Venerable in it, with my strength, I will never be his opponent!" Cheng Yun thought for a moment and had already decided that he would not touch this alchemy furnace again, so as not to release the Spirit Fire Demon Venerable.

"Help me, help me! As long as you are willing to save me, the deity can promise you anything!" Seeing that Cheng Yun did not respond for a long time, the Spirit Fire Demon Venerable in the alchemy furnace became anxious, and his voice became extremely eager.

Cheng Yun heard what the Spirit Fire Demon Venerable said, and stopped slightly, he had already obtained the semi-finished product of the Extreme Yan Dan, and there was nothing important at the moment, and it was okay to find out the origin and details of the Spirit Fire Demon Venerable here.

"If you want me to save you, tell me who you are, what tribe you come from, and why you are imprisoned in the alchemy furnace!?" Cheng Yun turned his head and asked the Spirit Fire Demon Venerable in the alchemy furnace.

"The deity is a member of the demon clan Lingyan clan, captured by the people of the Dayu Dynasty and sealed in the alchemy furnace, they were going to refine the deity into an elixir, but for some reason, they have waited for such a long time and have not acted! People outside listen, no matter who you are, which tribe you are from, as long as you are willing to open the seal in the alchemy furnace for the deity, the deity can grant you three wishes, with the strength of the deity! No matter what the wish is, it can be realized! The deity can make an oath! Never regret!" The voice of the Spirit Fire Demon Venerable was no longer as weak as before, he waited for a long time, and finally waited for Cheng Yun to appear, just like he grabbed a life-saving straw, in order to leave the alchemy furnace, no matter what the price was, he was willing.

After Cheng Yun listened, he was silent for a moment, he didn't speak, but he had already begun to mumble in his heart: "He is a member of the demon clan, no matter what the reason is, he was sealed in the alchemy furnace, and releasing him is a great danger to my human race, and I can't release him." ”

"The Demon Clan's Heaven-Rank Demon Beast, I've also seen it before!With the strength of the Heaven-Rank Demon Beast, it's really difficult to realize my wish!" Cheng Yun's mind flowed, and he wanted to ask what he wanted to know from the mouth of the Spirit Fire Demon Venerable.

"After the Heavenly Rank Demon Beast, there is also the Demon Venerable! After the Demon Venerable, there is also the Dao Demon! The deity is a Dao demon! With the ability of the Deity, he will definitely be able to fulfill any wish for you!"

"Where are the Demon Venerable and Dao Demon stronger than the Heavenly Demon!?After the Dao Demon, is there any stronger?" Cheng Yun struck while the iron was hot and asked questions one after another.

The Spirit Fire Demon Venerable seemed to be worried that Cheng Yun would not be satisfied and would not save him. After hearing Cheng Yun's question, he continued to answer: "The bloodline in the demon beast's body reaches its peak when it reaches the heavenly level, and from the demon venerable realm, it is not the bloodline that competes. It's the control of the rules and origin of the wilderness! Compared with the Heavenly Demon, the Demon Venerable has been able to condense a large amount of cost sources and see through a certain degree of rules! And the Dao Demon can control the rules! After the Dao Demon, there are the Demon King and the Demon Emperor! The demon clan who does not reach these two realms can only be respected, not called the king and the emperor! These two realms are not something that I can contact and know, everything I know has already been told to you, you quickly break the seal. Let me out!"

"If I release you, if you regret it, don't grant me my wish, or simply kill me, I can't lose money!?" Cheng Yun smiled coldly, that is, many monks of the same human race are all deceiving me, how can this demon beast of another race make Cheng Yun believe him with just a few words.

"I can make an oath! Let the will of heaven be notarized! If I go out. If I don't fulfill your wish as agreed, I will lose all my cultivation. Reduced to an ordinary beast!" The Spirit Fire Demon Venerable was hysterical, he just wanted to leave the alchemy furnace, even if it was a big price, he was willing to pay.

Cheng Yun shook his head and said, "I don't believe in any oath, let alone the will of the Heavenly Dao! You will give me the benefits first! Otherwise, I will not agree to release you!"

After hearing this, the Spirit Fire Demon Venerable in the alchemy furnace was no longer as hysterical as before, but remained silent.

"If you don't agree. I'm leaving! In your capacity, the place where you are being held is not something that can be entered casually, and you must know the difficulty of entering this place! If I leave, you will have to wait until the next person. I'm afraid that I will have to wait countless years before I can do it!" Cheng Yun smiled coldly, he was sure that the Spirit Fire Demon Venerable would definitely agree to his request.

"What benefits do you want!!?" Spirit Fire Demon Venerable's voice was no longer as eager as before, and he asked through the alchemy furnace.

Cheng Yun smiled, the Spirit Fire Demon Venerable really couldn't help but speak, he thought for a moment and then said, "First, I want you a demon pill! a demon pill that is enough for people to rise from the Qiyuan Realm to the peak of the Holy Soul Realm!"

"Yes, but the Blazing Sun Realm and Holy Soul Realm of the Terran monks cannot be reached by cultivation alone, even if I give you the Demon Pill, you will not be able to cross this bottleneck!" The Demon Pill is the person of the Demon Clan who condenses his own cultivation and bloodline to send the Demon Pill out, which also means that the Spirit Fire Demon Venerable has to reduce so much strength, although the price is huge, but the Spirit Fire Demon Venerable, who has been trapped for countless years, is also willing to agree, he has endured it for too long.

"Second, I want you ten drops of soul blood, and I want you three drops of demon bloodline blood!" Cheng Yun said indifferently and said his second request.

"It's just soul blood and bloodline blood, the deity promises you that it is! But it can be restored in tens of thousands of years, and the deity has spent an unknown number of thousands of years in this broken place!"

"Third, I want you to use the Heaven and Earth Yuan Fire in the alchemy furnace to refine a batch of pills for me!" Cheng Yun took out a storage bag, which included the pills obtained from the Tibetan Dan Hall, as well as the half-finished Jiyan Pill!

"No problem!Have you achieved these three things, and you will open the seal of the alchemy furnace for the deity!?"

Cheng Yun nodded slightly, and he said: "In addition to these three things, after you leave the alchemy furnace, you have to promise me a wish, I haven't thought about this wish yet, when I think about it, you have to fulfill it for me!"

"The people of the human race have a lot of hearts and eyes! The deity promises you! Quickly pass the things to the alchemy furnace, and the deity will handle your three things first!"

Cheng Yun punched out the seal, opened the seal of the alchemy furnace, and sent the storage bag through a hole into the inside of the alchemy furnace.

The third requirement is that Cheng Yun just wants to refine the Jiyan Pill into a finished pill, and other pills that are more valuable than the Jiyan Pill are just a cover-up.

"Terran, this is what you want! Hurry up and put it away! Let the deity out!"

From a hole in the alchemy furnace, the Spirit Fire Demon Venerable sent what Cheng Yun wanted from the inside.

Cheng Yun stepped forward, picked up these things, and after examining them carefully, he nodded with satisfaction, and then put them into the Qingguang Ring.

"Thank you Demon Venerable, if you don't want to do it, you want to stay in this alchemy furnace! If you agree, you have to stay in it! If you don't want to, you won't fulfill Cheng's wish! If you don't complete Cheng's wish, Demon Venerable, you think clearly before answering Cheng, Cheng will go first!" Cheng Yun didn't plan to release the Spirit Fire Demon Venerable from the beginning, and at this moment he said his wish, which made the Spirit Fire Demon Venerable in the alchemy furnace furious.

"Terran, you dare to play the deity!"

"I'll kill you!"

Cheng Yun smiled coldly, the Spirit Fire Demon Venerable was in the alchemy furnace, and he couldn't help him at all, he took out the magic weapon absolute sealing pen left by the torture luck, and drew a seal on the alchemy furnace.

"Seal! The sound of this place!" After drawing the seal, the roar of the Spirit Fire Demon Venerable dissipated in an instant, and the sound of this place had been sealed by Cheng Yun with an absolute sealing pen, no matter how the Spirit Fire Demon Venerable shouted, no one would hear his voice.

"There is a demon clan demon sealed here!Later people!Open the alchemy furnace slowly!Open the seal in it!Otherwise, the human race will have a catastrophe!" Cheng Yun thought about it, and left a sentence on this alchemy furnace, in case someone who didn't know why in the future inadvertently opened the seal and released the Spirit Fire Demon Venerable.

Ji Yan Dan had already arrived, and Cheng Yun didn't want to stay in this Si Dan Palace, so he rode on the Demon Rite, turned into nothingness again, and left Si Dan Palace. (To be continued......)
