Lin Feng left the trade fair and returned directly to the inn, and took out the ghost otter skin in the room.

This fat animal skin was densely covered with an incomparably amazing Yin and Netherworld aura, although it was soft and soft, but it was extremely tough, Lin Feng hit it with mana, it couldn't penetrate it at all, and even the monk's yang fire couldn't burn it!

The unrefined natural state already possessed such amazing and powerful characteristics, but Lin Feng still used the refining attribute of the immortal net to purify and refine the skin of the Ghost Otter Beast, making it from an extremely generous primitive state, abandoning impurities and becoming more refined, zuihou turned into a thin skin the size of three feet, but the leather surface was dark and translucent, exuding a terrifying and eerie aura!

Then, Lin Feng took out the Ghost Luo Banner that had not been used for a long time!

Ghost Luo Banner is the best magic weapon of the Ghost Spirit Gate in the Nanyue Xiuzhen Realm, although its category is classified as a magic weapon, but it is not an ordinary magic weapon, the ghost Luo Banner's ghost refining and soul detention effect, is a powerful function that many special types of treasures will have, but due to its own capacity limitations, the power of the Ghost Luo Banner can only be limited to the category of magic weapons.

But now, with the skin of the ninth-order ghost otter beast, the capacity and strength of the ghost luo banner will be greatly improved like never before, Lin Feng let the blood demon fire urge the demon flame, and completely fused this haode ghost otter beast skin into the original banner of the ghost Luo banner!

After the fusion, the ghost Luo Banner was further tempered by Lin Feng again, and then took out the Soul Hoarding Shrine from the Sumeru Illusion Ring, and used the soul of the eighth-order ghost king trapped in it to hit the banner with the Soul Curse, making it the Yuan Soul in the flag!

This eighth-order ghost was the soul of the Ghost King who was killed by Yan Gong with a shotgun bomb, and with its addition, the original Yuan Soul of Ghost Luo Man instantly became more powerful!

Fused with the skin of the ninth-order ghost otter beast and absorbed the soul of the eighth-order ghost king as the original soul, the surface and core of the ghost Luo Banner have undergone earth-shaking changes, and this great change has made it finally reborn, from the magic weapon level of the Ghost Luo Banner to the Yin Luo Banner of the magic weapon category!

Lin Feng refined his divine sense imprint into the Yuan Soul of Yin Luo Banner, making it a magic weapon of his own, the strength and capacity of Yin Luo Banner far exceeded that of Ghost Luo Banner by a thousand times and hundreds of times, and its power was not what it used to be, whether it was refining ghost things or dealing with monks, it would be more deterrent than ordinary magic weapons.

After the Yin Luo Banner was collected, Lin Feng swallowed and refined the Spirit Pill to restore his mana, and after the advanced Dan Formation Period, the refining technique of the Immortal Net had gradually changed, Lin Feng relied on the Demon Pill to the extent that it was no longer as powerful as before, if the strength of the materials and impurities was not too high, he would be able to quench it with his own origin spiritual power alone!

No matter how high the strength of the material is, Lin Feng uses his own origin mana, which is enough to urge the refining technique of the immortal net, but it can't be maintained for too long, and in the end, he still has to rely on the assistance of the demon pill, but this situation will become lighter and lighter, as his cultivation continues to improve, the origin mana will become stronger and stronger, and the role played by the demon pill will eventually be completely abandoned.

Using one's own origin mana to refine the material, you can overcome the fact that the demon pill is exhausted, and continue to cast the refining technique of the immortal net, and the consumed origin mana can be restored by absorbing the spiritual energy, or swallowing the spirit pill, and in some special cases, it will play an unexpected role.

The origin mana consumed by refining the Yin Luo Banner could be quickly recovered through the best Huiling Pill, and Lin Feng's Yuan Shen suddenly had a subtle movement at this time, he sensed this transmutation in time, his expression sank solemnly, and he hurriedly urged the Quenching Dragon Technique to enter the cultivation state.

A few hours later, when Lin Feng finished meditating and opened his eyes, his cultivation had progressed to the realm of the second layer of the Dan Formation Stage, which was almost a natural progression, the whole process was peaceful and natural, and there was not even a trace of excessive fluctuations or collisions, but a natural transformation and evolution, for Lin Feng, this subtle feeling was only once in his life!

After the advancement, Lin Feng's mentality was also extremely peaceful, and his thin state of mind made his spiritual platform clear, and he finally deeply understood the true meaning of the Dao, which is what many Yuan Infant monks said when they taught their experiences: The Tao is orderly and natural.

The close devouring of the immortal net provided Lin Feng with enough foreign spiritual power, and his devouring, decomposition, refining, and fusion, whether it was speed or efficiency, far surpassed other Demon Sect cultivators, and the pure origin mana was refined into his own body, and the improvement of strength was immediate, coupled with his own accumulation, causing the Yuan Shen to transform, and he naturally completed the advancement.

But it's a pity that this kind of advancement is very difficult, it needs to be restricted by many external environments, in most cases, the advancement after the Dan period is not possible, so most monks need to rely on the assistance of elixir in order to break through the bottleneck with all their strength and enter a higher realm.

Lin Feng's natural leap this time, benefiting from the continuous accumulation over the past few days, and the natural transformation made his realm quickly stabilize, so that it would not take a long time to consolidate the advanced Yuan Shen like before.

Even so, Lin Feng still closed his door, urging the Quenching Dragon Technique to continue to operate, allowing the spiritual power to continuously rush through the entire body veins to adapt to the strength of the Yuan Shen that had become stronger, and at the same time allowing the body to absorb the medicinal power of the Xuan Vein Pill, so that the body veins could keep up with the progress of the Yuan Shen.

On the second day, the trade fair of "Jindu Joint Auction" started on time, and the location was still the largest auction hall in Jindu City, but the items auctioned were all the Xiuzhen materials collected by Jinducheng himself, and there were more than a dozen of them in Jindu City, and among them, the three major families of Jindu, Shogunate, and Nanlong were the most powerful.

The most eye-catching thing about the Jindu joint auction is the unique best elixir in the Dabi Canyon, and among these elixirs, the most commendable is the Candle Flame Fruit!

In the "Entrusted Joint Auction" the day before, someone once traded the skin of the ninth-order ghost otter beast at the price of three small-ripe candle flame fruits, but the transaction failed to materialize, and everyone had no chance to see the three candle flame fruits.

Lin Feng was also full of expectations for the candle flame fruit that everyone watched, among the Bailing Bamboo Slips, there was a record of this spirit fruit, in fact, it was not unique to Dabi Canyon, but it had been extinct in other places, and now it may only be seen in Dabi Canyon.

The candle flame fruit is an elixir that can only be used by the Yuan Infant Monk, and at least above the medium ripe will have abundant medicinal power, and the small maturity of the Candle Flame Fruit is too low for the Yuan Infant Monk, and if it is barely used, the failure rate is as high as more than seventy percent, so most of them will cause waste, only the medium-ripe and large-ripe Candle Flame Fruit can receive immediate miraculous effects!

However, the small ripe candle flame fruit is a priceless treasure for the monks at the peak of the Dan period, and ordinary monks in the late stage of the Dan may not dare to swallow the candle flame fruit, because of its powerful medicinal power, it is very likely to destroy the monk's meridians or primordial spirits.

However, the peak realm of the late stage of the knot is only one step away from the baby, and if there is a small ripe candle flame fruit in hand at that time, it will definitely be able to accumulate more mana and lay a solid foundation for the future baby.

Although it is extremely precious, the three major families of Jindu City, in order to attract a sufficient number of Xiuzhen Shili to participate, still let out their mouths before, promising that in this trade fair, there will be a figure of Candle Flame Fruit!

The Jindu joint auction was presided over by the Jinhong ancestor of the Jin family! The major Jindu city Xiuzhen Shili who provided the lot had a representative sitting on the side, and once the transaction price met their requirements, the owner of the lot would signal to the Jinhong ancestor.

The first shot of the Jindu joint auction was very good!

In front of everyone's eyes, Jin Hong Ancestor slowly flicked his hand on the wide desktop in front of him, and more than a dozen fist-sized dark blue spirit ores fell down in unison.

Lin Feng's expression changed suddenly, and his gaze fell on the dozen or so spirit ores for a long time, and at this time, many monks around him had already begun to compete for the auction, and the materials produced were all refined, each of which was enough to make people's hearts pound.
