Only after the death of monks and demon beasts can their souls become lonely souls, and the chance of lonely souls surviving alone is inherently small, and some harsh environments and conditions are required, such as the land of the Yin Vein.

After surviving, the lonely soul can either continue to possess the corpse before it was alive, or it can choose a new body to live in by invading the body, thus forming a lonely soul corpse. The Lonely Soul Corpse can condense both the Pill and the Yuan Infant through cultivation.

There are very few lonely souls that can survive for more than a thousand years, and it is very likely that they will be captured by demon cultivators and refined into some magic weapons and magic weapons to increase their power.

Once the lonely soul corpse can survive for more than a thousand years, this kind of lonely soul will become the king of the lonely soul corpse. Once it is captured and refined into the Lonely Soul Corpse King, it will become a sharp weapon for the refiner, and the foundation building period monks can drive it.

Not only does the Lone Soul Corpse King absolutely obey the orders of the refiner, but he can also cultivate and advance on his own, and even continue to follow the refiner even after the success of the tribulation. The Lonely Soul Corpse King is similar to the Ghost Spirit, etc., he doesn't have much spiritual wisdom and knows how to cultivate. As long as it is not destroyed, its cultivation can be advanced to the Demon Venerable level.

When his cultivation breakthrough reaches the Demon Venerable level, he will immediately have his own divine consciousness, so he can obtain a true physical body by invading the body. Like the ghosts and gods, the object of the invasion can be either the owner of the Lonely Soul Corpse King or other monks.

The Lonely Soul Corpse King's own offensive and defensive abilities are the same as those of monks and monsters of the same rank and level, and if his soul is attached to special materials, his offensive and defensive abilities will be greatly improved.

The primordial infant containing the lonely soul in the Lonely Soul Corpse King can change its sojourner at any time, but the lonely soul can only follow the master's side, even if the tribulation is successful, it must wait until the master succeeds in the tribulation before he can fly to the immortal and demon realm with the master.

The Lone Soul Corpse King has two biggest advantages, one is that even after ascending to the Immortal Demon Realm, it does not need additional refining, and it can also be used by the master without any obstacles.

The second is that the connection between it and the refiner is even closer, as long as the refiner does not die, the Lone Soul Corpse King will unconditionally obey the monk's drive. The Ghost Ghost is different from the Lonely Soul Corpse King, and can only be driven if the monk controls the corresponding Ghost Banner and can provide enough crystal.

Thinking of these contents recorded in the Nine Mysteries Sutra, Feng Fan was a little amazed. If you can get the Lonely Soul Corpse and refine it into the Lonely Soul Corpse King, you will have another weapon.

Although Feng Fan was only a monk in the foundation building period, once he encountered a lonely soul corpse, it was possible to capture it with the Five Elements Xuanmeng Primordial Array, and then refine it into a lonely soul corpse king according to the records of the Nine Shadows Xuanmeng.

After studying the refining methods and materials of the Beast Soul Rune, the Ghost Soul Banner, and the Lonely Soul Corpse King, Feng Fan successfully cultivated the Nine Shadows Mystery Escape. This escape method is relatively simple to cultivate, but after using it, it will almost exhaust one's true yuan, and it will damage one's cultivation, and it will take a long time to recover.

Feng Fan used his divine sense to explore the ten ghost spirits in the ghost spirit banner left by the strong man in the black robe, and found that they were all at the level of cultivation in the middle and late stages of foundation building, and all of them were demon beast ghost spirits, which made Feng Fan overjoyed.

This also means that if you open the Ghost Spirit Banner to drive out all the Ghost Spirits, there will be ten Ghost Spirits who are in the middle and late stages of foundation building to attack the opponent together, and their power is incomparable.

Moreover, these ghost spirits seem to have the opportunity to advance to become Huadan-level ghost creatures, it seems that these ghost spirits are not easy to come by, and they must have spent a lot of energy on the strong man in black robes.

Eight precious materials were required to refine the Ghost Banner, the most precious of which was a skin of a fourth-rank or higher demon beast, which was just right for the blue-eyed green-eyed toad that he had killed a few months ago.

In addition, you also need Soul Dementor Ice Jade, Millennial Deciduous Wood, 10,000-Year Purple Sandstone, and four other materials, and then add a drop of Natal Essence Blood to successfully refine it. It's just that the success rate of magic flag refining is extremely low, and even senior refining masters have a high failure rate.

This is not a problem for Feng Fan, who has the ability to copy phantoms, as long as he gathers all kinds of materials and then copies Phantom in large quantities. If you fail once, you will do it ten times, and if you fail ten times, you will do it a hundred times.

This kind of ancient treasure will never be delegated to other cultivators to refine it, after all, this treasure can bring bloody wind and rain to the mortal cultivation realm! Anyone who sees the ghost banner will not hesitate to snatch it!

Even if the Ghost Banner is successfully refined, it is necessary to regularly consume the true yuan of the owner or crystal jade to nourish the ghosts in the Ghost Banner, otherwise the progress of the Ghost Banner will be extremely slow.

Feng Fan was not worried at all, because the Mixed Spirit Devouring Yuan Bead could absorb the true element in the body of a monk or demon beast, as long as the true element stored in it was regularly supplied to the ghost flag.

In addition, in addition to the crystal jade, the ghost of the ghost can also improve the cultivation by devouring the soul of a monk or demon beast, the inner pill, and the primordial infant, although this process is also slow, but it is slightly faster than absorbing the crystal jade.

Feng Fan finally understood why the black-robed strong man didn't have a ghost banner in his hand, and if the early Huadan monks encountered a demon beast above the Huadan stage, they could only flee from the wind.

A person like Feng Fan, who can kill a demon beast or monk at the Yuan Infant level through the five elements Xuanmeng Array and the Mixed Spirit Devouring Yuan Bead, two anti-heaven treasures, can be said to be unique in the mortal cultivation realm. In addition, the success rate of refining the ghost banner is extremely low, so even if ordinary monks gather the materials, it will be difficult to succeed in refining them if they are not sufficient.

As for the refining of the Lonely Soul Corpse King, in addition to the Lonely Soul Corpse that is more than a thousand years old, it is also necessary to mix the hard material Deep Sea Titanium Essence and the Soul Dementor Ice Jade to refine the Lonely Soul in order to succeed. The Soul Dementor Ice Jade, the Deep Sea Titanium Essence, and the Thousand Years of Lonely Soul Corpse are all extremely rare things, and Feng Fan has no hope in a short period of time.

In addition, a formation is also introduced in the Nine Mysteries Sutra, called the "Soul Leaving Array". The Soul Separation Array is a very simple phantom array, so it is not too difficult, and the key to this array is that it is extremely helpful for refining ghosts and searching for souls.

Because the Soul Separation Array has a great effect, Feng Fan learned the layout of the Soul Separation Array according to the Nine Mysteries Sutra. Feng Fan then practiced a kind of soul searching technique in the Nine Mysteries Sutra, this spell can be used mainly to use his own true yuan plus a few simple spells and set up a soul separation array to cast, after subduing the opponent, you can search out all the opponent's memories.

This kind of soul searching technique is different from ordinary soul searching techniques, which are often unable to be used when facing souls that are higher than oneself. Even if you force it, you will be counterattacked. The peculiarity of this kind of soul searching technique is that even if the opponent's cultivation is higher than that of the caster, his soul can be easily searched with the help of the Soul Separation Array.

Feng Fan calculated the time, and it was almost the once-in-a-decade large-scale trade fair of the Golden Moon Ancient Kingdom. Feng Fan was going to leave the Hanhai Forest for the time being and go to Fengshi Town to find all the materials that were missing for refining the Ghost Banner.

Before leaving, Feng Fan first recognized and refined the blood of the ghost spirit flag, and then copied a large number of super-grade crystals and super-grade crystals. After all, if you want to exchange the things you need in the trade fair, you must have enough crystal jade, and as Feng Fan's own strength has reached the foundation building stage, he is ready to exchange high-grade crystal jade for what he needs.

The things he needs are precious, and I'm afraid that it will not be easy to trade with low-quality jade. As for the thousand-year-old spirit grass, spirit pill and other items that can be exchanged, there are still some in the Five Elements Xuanmeng Ring. It's just that this trade fair can even meet Yuanying-level monks, so unless it is a last resort, Feng Fan will not take out this kind of thing in exchange for the materials he needs.

Copy the lost true element of the Phantom Crystal Jade, and Feng Fan replenishes all of them through the Mixed Spirit Devouring Yuan Bead. Although the Soul Devourer Orb was still purple, its color was much darker.

Feng Fan threw out several pieces of super-grade jade, and under the concentration of a true element, the crystals were embedded in the ground.

Feng Fan waved the Five Elements Xuanmeng Flag, and the original magic circle of the Five Elements Xuanmeng Array was immediately in a dormant state. Feng Fan was ready to continue to keep this magic circle, as long as he relied on the Five Elements Xuanmeng Banner, he could urge it at any time.

After doing all this, Feng Fan flew towards Fengshi Town, and approached his destination a few days later. Before Feng Fan entered Fengshi Town, he opened a disguise spirit talisman and changed his appearance into the appearance of another young man, and no monk at the Yuan Infant level or below could see his true face.

After arriving at Fengshi Town, Feng Fan discerned the direction of the Hanhai Secluded Forest, opened an escape talisman, and suddenly appeared in a wilderness dozens of miles outside Fengshi Town.

Feng Fan carefully explored with his divine sense, and after confirming that there were no other monks around, he sacrificed the Five Elements Xuanmeng Banner and began to lay out the Five Elements Xuanmeng Array primordial magic array.

Because in this large-scale trade fair, there is a high probability that some unexpected things will happen during the exchange. In order to increase security, Feng Fan set up the Five Elements Xuanmeng Array Primordial Circle here. If you encounter a major danger, you can immediately use the escape talisman to teleport here, and then escape with the help of the Five Elements Xuanmeng Array Primordial Circle.

More than two hours later, the large array had been successfully arranged. Feng Fan threw out a few pieces of crystal jade to maintain the large array. Feng Fan waved the Five Elements Xuanmeng Flag, and the large array was in a dormant state in an instant.

The town of Fengshi is bustling with activity, breaking the usual silence. The large-scale trade fair of the Golden Moon Ancient Kingdom, which takes place every ten years, has begun, and many monks from various sects and major families have appeared here. An ordinary-looking young man walked in Fengshi Town, and it was Feng Fan who came to participate in the trade fair after changing his appearance.

Similar to the medium-sized trade fair, this large trade fair is still divided into two zones. One of them is an indoor area and one is an outdoor area. The Peak Stone Pavilion is still an indoor trading area, which is also divided into eight areas, and the things in the indoor trading area are more precious than the outside.

Feng Fan was cultivating hard ten years ago, so he didn't participate in that large-scale trade fair in the Golden Moon Ancient Kingdom. But because he had participated in the medium-sized trade fair fifteen years ago, Feng Fan was no stranger to the situation in Fengshi Town.

Wandering in the flow of people, Feng Fan carefully watched the things placed in the outdoor trading area, most of which were some low-level talismans, magic weapons, calligraphy, etc.

Feng Fan came to a paving and saw a middle-aged foundation-building early initial level black-clothed monk standing behind the paving. Feng Fan stopped his eyes on a book Jane, explored it with his divine sense, and found that it was a book about making talismans, and the name of the book was "Talisman Daquan".
