Cuiyun Zhenren controlled the flying sword and sent Lin Feng back to Chiyun Peak all the way. Seeing Lin Feng return to the house, Cuiyun Zhenren turned around and left Chiyun Peak after sighing.

It was night, and in the dead of night, Lin Feng turned over and got up, and took out a quaint Qiankun ring from his arms. This is not Lin Feng's original Qiankun ring, but a Qiankun ring that Chifeng Zhenren sent into Lin Feng's arms with the help of the wind when he fanned the gale. Lin Feng knew that the master made that posture of disdain for himself before throwing this Qiankun ring to himself, because he didn't want the matter of this Qiankun ring to be known by others. It is also because of this that Lin Feng is silent.

Lin Feng picked up this Qiankun ring and took a good look, it was the extremely simple Qiankun ring that Chifeng Zhenren had been wearing on his hand in his memory. The front of the ring is set with a strangely shaped gemstone that roughly looks like a mountain.

Mana was injected into the Qiankun Ring, and the space inside the Qiankun Ring was displayed in front of Lin Feng's eyes.

There is nothing else in this Qiankun ring that Chifeng Zhenren gave to Lin Feng, it is just a concise record of information one after another. Lin Feng took out the spirit slip and began to check the title of the book written on the cover page of the scroll spirit slip.

"Miscellaneous Discussions on the Qi Training Period", "Miscellaneous Discussions on the Foundation Building Period", ...... "Miscellaneous Discussions on the Mahayana Period", first of all, are the seven parts of the spiritual simplicity related to cultivation, and the spiritual power fluctuations are stronger than the other.

"Identification of Yellow-level Medicinal Materials", "Identification of Xuan-level Elixirs", "Summary of Yellow-level Danfang", "Summary of Xuan-level Danfang", "Primary Alchemy Techniques", "Advanced Alchemy Skills". There are a total of six Elixir related Lingjian. It would not be enough to say how high the value was, but for a long time, Lin Feng should not need to go to the outside world to find knowledge related to pills. Heaven and Earth Xuanhuang is a common way to distinguish grades in the cultivation realm, the heaven-level and earth-level pills are already quite high-grade treasures, and a sect like Yanyang Sect does not have the ability to refine ground-level pills, so it does not have the energy to collect ground-level pills.

"Spirit Ore Identification", "Essence of Fu Seal", "Summary of Yellow Level Refining Formation", "Appreciation of Xuan-level Refining Formation", "Primary Refining Technique", "Advanced Refining Technique", and "Nine Heavens Xuan Array Catalogue" are seven parts of the spirit related to refining. The "Nine Heavens Xuan Array Catalogue" seemed to be very powerful when it sounded like a powerful name, and Lin Feng took it out and wanted to try to read the information in the spirit slip.

The information is read, but it is pitifully scarce.

"The Nine Heavens Xuan Array Catalogue is the high-level formation that my Chiyun Zhenren has collected all his life, including twelve Xuan-level top-level Xuan Miao formations, eight earth-level formations, and a broken heaven-level formation 'Nine Heavens Xuan Array'. These formations are extremely exquisite, and it is impossible to truly learn these formations without sufficient refining foundation. The first Xuan-level top-level formation is called "Beidou Heaven Swallowing Array", which is one of the advanced formations of the yellow-level formation "Beidou Seven Star Array", and only after the realm reaches the Mahayana period can you start trying to study it...... "The information is gone here." I didn't say that I was the first Chiyun Zhenren, so it is very likely that this Nine Heavens Xuanjing Array Catalogue was handed down from the first Chiyun Zhenren. Lin Feng frowned, and after thinking about it, he established contact with Lin Wanshan. After introducing the origin of this Qiankun ring to Lin Wanshan, Lin Feng asked the question about Lingjian.

"Can you only read a small part of the information? It should be a high-level spirit with a spiritual seal. On the road to cultivating truth, many of the theories that prevailed in the later period were not applicable in the early stage. The same is true for refining and alchemy. Many of the truths contained in those top-level formations are not applicable at the stage of cultivating yellow-level formations, and using Lingjian to learn the information of high-level formations in advance will not be beneficial to you, but will disturb your brain, giving you some more troubles that you don't have to worry about when practicing low-level formations. It is also to prevent this from happening, some Lingjian will seal the knowledge in the Lingjian at a graded level, and the monk can only read the information at this stage when he meets the pre-requirements of a certain level of sealing. ”

Lin Feng didn't bother to read the information in the other spirit slips, and took out the last volume of spirit slips.

"Purple Sky Strange Fire Spectrum".

Lin Feng's interest was raised. The alien fire is the collective name of all kinds of rare flames that are different from ordinary flames in the cultivation realm, and the high-level alien fire is a treasure that cannot be found in many weapons in the cultivation realm, and it can make a breakthrough in combat effectiveness, refining weapons, and alchemy ability, and stand out in the cultivation of weapons in the same realm.

Lin Feng began to try to read the information in the spirit of this "Purple Sky Strange Fire Spectrum".

"The creation of heaven and earth, the magic of the universe, in the mysterious place, gather the power of the spirit, burn the sky and the earth, and there is a fire mystery.

Alien fire refers to the strange fire of heaven and earth that is stronger than the strength of the monk's natal true fire, has unparalleled power or special functions, and naturally arises between heaven and earth. Today, I will count the known different fires in the Xiuzhen Realm, collect detailed information, and collect real patterns to write this "Zixiao Strange Fire Spectrum", hoping to help the cultivation of various realms in the Xiuzhen Realm.

According to the different fire and mystery, the different fire between heaven and earth can be classified as the fourth level of heaven and earth Xuanhuang. The "Zixiao Strange Fire Spectrum" records the relevant information of the nine heaven-level fires, eighteen earth-level fires, thirty-six Xuan-level fires, and seventy-two yellow-level fires known in the Xiuzhen Realm.

The strength of the yellow-level alien fire may not be much stronger than the ordinary natal true fire of weapon cultivation, and because of the limited strength, even if it is refined into the natal true fire, it may not have a stronger power than the original natal true fire. However, it often has some special effects, and in many cases, it is more mysterious than ordinary natal true fire.

And the thirty-six kinds of Xuan-level fires, both in terms of flame intensity and their degree of mystery, have far surpassed the ordinary natal true fire. This level of alien fire can already allow the weapon cultivation to have a considerable degree of improvement in combat effectiveness and refining alchemy ability.

Eighteen types of prefecture-level fires......

Nine Heaven-level Alien Fire ......

Xuanling Chiyan, the seventy-second place on the yellow-level alien fire list. It is commonly found in the cave blessed land where the fire system is rich in spiritual power, the flame is red and yellow, and the strength is average when used in battle, but it has a strong effect of refining impurities in refining alchemy.

...... "After the introduction of Xuanling Chiyan, it is a real record of Xuanling Chiyan's use of Xuanling Chiyan's alchemy. The Xuan-level and yellow-level different fires all have corresponding images, but when it comes to the earth-level flames, there are seven kinds of different fires that only have text introductions and no corresponding images, and when it comes to the heaven-level flames, there is no one with an influential introduction.

Lin Feng thought of the cluster of strange fires in the Dark Fire Immortal Pot, which he called "Nether Ghost Fire", and after thinking about it, after sifting through the "Purple Sky Strange Fire Spectrum", he established contact with Lin Wanshan again.

"Father, among the many spiritual texts left to me by my master, there is a volume of "Zixiao Strange Fire Spectrum", which records the relevant information about the known strange fire in the cultivation realm. I sifted through it and found five different fires that were similar to the dark fire in the pot you described. Let me tell you, if you look at the dark fire in the pot, which different fire is the most imaginary.

There is really a ghostly ghost fire in the strange fire spectrum: there are many shadows, the day is dark, the day is ghostly, the soul is fed, and the primordial infant is transformed. The image of a white pale flame heart wrapped in black flames has a miraculous effect on the soul of the primordial infant. It lacks effectiveness in alchemy refiners, but it is especially weird in battle, and can directly attack the opponent's Yuan Infant to a certain extent. And against the evil cultivators who use the Yin Soul as a means of attack, they can almost cross the Great Realm to win.

Isn't it this kind of strange fire? It doesn't seem to be weak, it ranks nineteenth among the Xuan-level different fires, and the black flames don't seem to be of a very low grade. ”

"It's not this, although the dark flame in this Hellfire Immortal Pot is also a black flame, the flame heart is not white. Moreover, although the flame is black, the temperature is extremely high, and there should be good achievements in refining alchemy. ”

"Then look at this. Jialan Demon Flame, the twenty-sixth rank of Xuan-level Alien Fire. Dark flames, pale blue flame hearts. ”

"Needless to say, it's not this. The fire in the pot is black or black-brown all over the body. ”

"Is it dark brown or black all over? Father, there are only two left, one is the Spectral Ember Burning Flame, which ranks first among the Xuan-level Strange Fires, and the other is the Ground-level Strange Fire Netherworld Flame. Lin Feng's voice became excited. According to the "Zixiao Alien Fire Spectrum", even yellow-level alien fires are quite rare, and among all the instrument cultivation, at most, only one in a thousand lucky people can subdue yellow-level alien fires. Those who can possess Xuan-level alien fire are already the lucky ones who meet the top in instrument cultivation. Lin Feng was originally very satisfied with being able to possess a Xuan-level fire, but now, there were only two kinds of fires left to satisfy the image of the fires in the pot, and Lin Feng was a little greedy to hope that the fires in his magic weapon could be the Netherworld Flames that had reached the level of the earth.

"The flames are brown or dark brown, but because the flames are extremely condensed, they don't emit a strong light, and they feel like an ordinary flame during the day, but in a black environment, they can almost melt into the black. The powerful alien fire that ranks first among the Xuan-level alien fires. The heat of the extremely condensed alien fire, the existence of high temperature is almost not felt around the phantom ember incineration, but the temperature inside the flame has exceeded the level of the Xuan-level alien fire, and has reached the level of the ground-level alien fire. He has quite outstanding performance in both battle and alchemy, but because he has no other outstanding characteristics, he can only be relegated to the Xuan-rank Alien Fire rating. ”

"That's right, it should be this Pyoger Burning Fire, which is the kind of extremely condensed characteristic, and there is no heat or brightness in the surrounding area at all. However, if the Qi Gathering Pill is put in, it can refine the impurities in the Qi Gathering Pill in a very short time. ”

"Are you sure?Father, don't listen to the introduction of the Netherworld Flame anymore?" Knowing that he had the first Xuan-level Alien Fire, Lin Feng's voice actually sounded a little disappointed, Lin Wanshan understood what Lin Feng meant, so he asked Lin Feng to talk about the characteristics of the Netherworld Flame.

"Netherworld Flame, pure black fire without a trace of variegation, ranked thirteenth among the ground level fires. Born in a desperate situation full of yin spirits, with yin spirits or primordial babies as nourishment, it will grow into a very strong alien fire existence soon after birth. Nether Flame is the origin form of Nether Ghost Fire, and the advantage of Nether Ghost Fire is that Nether Flame has all of them, and it is tenfold stronger. Pure combat fire, nothing has been achieved in refining weapons and alchemy, but the power of the battle is absolutely terrifying. As soon as he got close to the Netherworld Flame, he would feel an absolutely cold feeling emanating from the bottom of his heart...... "Lin Feng is helpless, this Netherworld Flame is different from the strange fire in the pot described by Lin Wanshan in several characteristics, and the strange fire in the pot is not the terrach-level fire that Lin Feng expects after all.

"Be content, the alien fire that ranks first among the Xuan-level alien fires, how many instrument cultivators do you have to envy to death? ”
