Most of the sects in this cultivation realm, as long as they are sects that have inherited for a little while, all have their own unique secret techniques, such as the top three sects in Zhaoyou Kingdom, the alchemy of the Corpse Nightmare Sect, the sword art and the sword formation method of the Spirit Sword Mountain, and the puppet technique of the Tianyin Palace.

Of course, these sects also have their own unique treasure refining methods, such as the seven kinds of prison wheels of the unique treasure of the Corpse Nightmare Sect, the spirit sword refining methods of Spirit Sword Mountain, and the eight puppet refining techniques commonly known as the Tianyin Eight Puppets of Tianyin Palace.

And the sworn enemy of the Corpse Nightmare Sect, it is said that the Six Ghost Sect that has been established for more than 200,000 years, naturally also has its own unique secret treasure, the legend is that there were originally a total of twenty-seven kinds, but the six ghost gates that have been inherited for a long time have gone through ups and downs several times, after several civil strife and foreign invasions, most of the twenty-seven kinds of secret treasure refining methods have been lost, and only thirteen are left in the end.

Because these thirteen treasures are all in the shape of gloomy skeletons and white bones, they are called "thirteen skeletons" by the world, and each of them is a mysterious and abnormal, and powerful treasure.

But what embarrassed the Six Ghost Sect is that this is called the "Thirteen Remains" treasure, because it is a treasure refining method handed down from ancient times, so either because of the scarcity of materials, or because the refining technique is too mysterious, so the success rate and production rate of these thirteen treasures are very, very low, so low to the extreme, even the Six Ghost Sect itself did not collect these thirteen treasures, and only five of them are very pitiful and embarrassing.

Yin Ning's current "soul biting" is ranked tenth among the "thirteen remains", and now this spirit weapon is actually Chen Yuqian has just completed the first step of refining, so it is only a fourth-order spirit weapon, and the "soul biting" that has truly completed its form will reach the level of a ninth-order magic weapon, and because it uses the method of the ancient cultivation system, it belongs to the ancient treasure, and its true power must be stronger than some ordinary first-order spirit treasures.

Of course, Yin Ning still has a long way to go to achieve the final form and upgrade the "Soul Rodent" to a ninth-order magic weapon, even if its refining ghoul cry has taken away most of Chen Yuqian's refining talent and memories about refining, it is still not optimistic.

Not to mention the more than 100 kinds of spiritual materials that Yin Ning had never even heard of before he had even heard of the "Soul Rodting" level, let's just say that those ancient cultivator techniques that were matched with the "Soul Rodting" were extremely complicated and mysterious, and Yin Ning was dizzy at first glance, and he had no clue about the ancient cultivator techniques, which could make Yin Ning daunted.

"It's no wonder that the Six Ghost Sect will distribute the refining method of the secret treasure of the sect 'Soul Biting' to the disciples of the sect at will, and they are not afraid of being seized by the Dead Enemy Sect, it turns out that this treasure actually needs so many spiritual materials, and the success rate is so low, it is simply chicken ribs for many people! ”

Yin Ning took out a dark black jade slip from the storage bag that originally belonged to Chen Yuqian, it was the jade slip that recorded the method of refining the "soul bite", Yin Ning only put this jade slip on his forehead, and after watching it for a while, he immediately opened his eyes full of shock, shook his head and sighed.

But immediately Yin Ning laughed in ecstasy: "But it's a pity that the Six Ghost Sect would not have expected that in the Corpse Nightmare Sect, their sworn enemy, there would really be such a rare refining genius in the world, and he really understood those ancient cultivator techniques, and also collected a part of the spiritual materials that are difficult to find, and this 'soul bite' was really refined, although it was only a preliminary completion, but it was definitely enough to surprise the Six Ghost Sect, but now this peerless treasure is completely cheap for me." ”

Yin Ning held the black and red skull with one hand, and laughed proudly for a long time, but after laughing, Yin Ning immediately became embarrassed, he looked at the "Soul Rodent" in his hand, and then looked at the Ghoul Witch May Cry who put away his corpse and stood still like a guard, and frowned: "Is it me who sacrifices this 'Soul' by myself?" Or let Devil May Cry sacrifice?"

"Soul Rodent" is a powerful and wonderful ancient treasure, of course, Yin Ning wants to sacrifice it himself, but through the experience of refining treasures in the previous few times, Yin Ning also knows that he has low cultivation qualifications and low comprehension, and how slow the speed of prohibition in the sacrifice treasure is, compared with his own refining ghoul May Cry, it is completely like a turtle crawling.

To give full play to the strongest combat power of the "Soul Eater", of course, it is necessary to make the Devil May Cry Sacrifice that can refine all the prohibitions in the fourth-order and fourth-order spirit weapon "Soul Rodting" in a short period of time, but Yin Ning was also worried after the battle against the demonized monsters in the Underground Demon Palace.

Although Devil May Cry and Ghost Marks are Yin Ning's natal refining corpses, they are the existence of Yin Ning's weal and woe, and the magical spells and sacrificial treasures they have practiced are equivalent to those magical spells and sacrificial treasures that Yin Ning has practiced, but the natal refining corpses are not Yin Ning's real siblings after all, they are likely to be abandoned by Yin Ning to protect the handsome and sacrifice with their tails cut off to survive, just like when they dealt with the demonized monsters in the underground demon palace.

In the underground demon palace, it was because of luck, Yin Ning evil two-headed natal refining corpse, but it was damaged and not hit the vital point, completely annihilated in this world, but Yin Ning, who did not believe that he would always be so lucky, immediately had a sense of distress, thinking that he should not rely too much on the two-headed refining corpse in the future, especially letting the refining corpse sacrifice with many powerful treasures, otherwise if the refining corpse is damaged or destroyed, then his own strength will be immediately greatly reduced.

Yin Ning has the heart to temper himself, and even when his refining ghoul Devil May Cry is able to devour and seize the innate characteristics of all things at will, Yin Ning thinks that he is going to learn a cultivation skill, and he often has the mind to spend time cultivating a few powerful spells, so that even if he is separated from Devil May Cry and Ghost Scar refining corpses at both ends in the future, he can still have the ability to survive in the cultivation realm.

Therefore, Yin Ning now hesitated about who would sacrifice the "Soul Rodent", which might be the spiritual weapon with the highest potential that he had obtained now.

Of course, Yin Ning could have taken the initiative of letting Devil May Cry sacrifice the "Soul Rodent" to greatly increase his strength in order to deal with the trip to the Night Desolation Country where evil cultivation was rampant, and then at the right opportunity, he would erase the mark of the sacrifice and then let himself be sacrificed, but if he did so, the disadvantages would be extremely great.

In terms of the sacrificial refining of treasures, although they can be transferred by erasing the sacrificial refining marks, it is difficult to completely erase those sacrificial refining imprints, and they will leave some traces more or less.

If there is a sacrificial refining mark in the treasure, then when another person sacrifices the treasure, the difficulty will increase by at least ten times, and if some of the sacrificial refining imprints are deep enough, the time spent on the sacrificial refining will even reach dozens or even hundreds of times that of the original sacrificial refining of this treasure, so that the treasure will become completely useless, because there are really few people who will spend a lot of more than ten years or even decades to sacrifice a treasure, unless that treasure is a peerless treasure above the spirit treasure and spirit treasure level.
