To condense a Nascent Soul, the inner demon tribulation is the most dangerous.
If I cultivate the Nine Transformations Soul Refining Art to a certain level, my divine soul will definitely be more resilient, giving Zhang Ling more confidence in dealing with the inner demon tribulation.
Moreover, the Elixir of Soul Enhancement's recipe is very simple, using very few materials, only three in total, the most important of which is Soul Nourishing Wood, and the other two materials are called Seven-Colored Seven-Leaf Flower and Cloud Swallowing Stone.
The main material is naturally Soul Nourishing Wood, which Zhang Ling has on him, and he has a mysterious bead that can cultivate spiritual plants, so there is no need to worry about the consumption of Soul Nourishing Wood.
The biggest obstacle has been solved invisibly, Zhang Ling feels that the Elixir of Soul Enhancement was prepared for him.
After all, this kind of Soul Nourishing Wood was extremely rare even in ancient times, let alone in the current cultivation world, I'm afraid few people have ever seen it. Even fewer would think that he possesses an entire Soul Nourishing Wood tree.
As for the other two materials, Zhang Ling was a little troubled.
He had seen the Seven-Leaf Flower before, it's just a second-grade rare spiritual herb that can be used to refine several kinds of elixirs suitable for Foundation Establishment cultivators, and its value is not very high.
But he had never heard of the Seven-Colored Seven-Leaf Flower.
As for what Cloud Swallowing Stone is, Zhang Ling had never heard of it either, it sounds like some kind of spiritual ore.
It seems that these two materials are not easy to find, I will check the relevant classics after returning to Fire Cloud Island to see if I can find them.
Zhang Ling then put away the Soul Refining Diagram, this treasure is definitely more valuable than the ancient treasures in his hands. Although the Soul Refining Diagram is only an auxiliary treasure, in his heart, it is second only to the Bronze Ancient Lamp.
I wonder who refined the Soul Refining Diagram, it is likely a treasure passed down from ancient times.
At the same time, he thought of the process of obtaining this diagram, he found it in a hidden cave in the water. There were also many elixirs refined with turbid Qi in that stone room, and there was also a Nascent Soul female cultivator sealed by an ice coffin.
This proves that the original owner of that hidden cave was definitely not an ordinary cultivator. I'm afraid they were at least a Nascent Soul monster.
Zhang Ling smiled, and didn't think anymore, with a wave of his hand, two more things appeared in front of him. A palm-sized fragment of iron, and a white jade box.
The iron fragment was obtained from killing the scarlet monster in the Ice Fire Jade Mine. The jade box was found on the unnamed island in the Azure Spirit Sea on the fifth floor of the Tianyuan Secret Realm, which was suspected to be the Divine昊 Sect.
Zhang Ling flicked his finger, and the jade box was opened, inside was the strange spiritual bone and half a bottle of essence blood. There were also several ancient jade slips.
The spiritual bone and essence blood are not ordinary things, after many years, the spiritual power on them does not seem to have decreased.
Looking at these two things, Zhang Ling could clearly feel a strong spiritual pressure.
However, what he wants to study now is not these two things, with a wave of his hand, he took out the jade slip from the box. Then he closed the jade box again and put it into the storage bag.
There were a total of five ancient jade slips, which recorded a lot of ancient immortal texts, Zhang Ling began to study these ancient jade slips.
In the blink of an eye, several days passed, Zhang Ling was still studying these ancient immortal texts in the stone house. At this moment, he was holding an ancient jade slip in his left hand, and an iron fragment in his right hand, identifying the information in them back and forth.
This iron fragment is engraved with dense ancient texts, after studying for a few days, comparing it with the demon patterns in the ancient jade slip, he finally deciphered the ancient texts on it.
The words on the iron fragment are all engraved with demon script, recording what seems to be a cultivation method. This cultivation method does not seem to originate from anywhere, the words 'Blood Demon' appear repeatedly, and it seems to be a demon refining master's cultivation method.
This made Zhang Ling think of the Blood Demon Sect among the Ten Great Sects.
The Blood Demon Sect is the only sect among the Ten Great Sects established by a demon refining master. This sect has the fewest number of people among the Ten Great Sects, and its power seems to be the weakest. But at the same time, it seems quite mysterious.
Zhang Ling only heard that the current Sect Master of the Blood Demon Sect is a Nascent Soul old monster called Blood Bone Old Man, who is said to be the strongest person in the Blood Demon Sect, with the strength of a Nascent Soul Late Stage cultivator.
It is said that two hundred years ago, this person slaughtered a medium-sized sect, and then the Blood Demon Sect was jointly condemned by the other major sects once, and after that, there were few reports of the Blood Demon Sect's deeds.
The cultivation method on the iron fragment is also incomplete, the most important cultivation part is not recorded, but several secret techniques are recorded instead.
And this information is only recorded on one side of the iron fragment, there are also many words on the back of the iron fragment, also written in demon script.
What surprised Zhang Ling was that the back also recorded a treasure refining technique, and it was closely related to a treasure in his hand. He flipped his hand and the Blood Soul Cauldron appeared in his hand.
The treasure refining technique on the back of the iron fragment is also different from ordinary treasure refining methods, it has no name. After Zhang Ling studied it, he found that this treasure refining technique was very strange, very similar to the Blood Refinement method.
The Blood Refinement method is a special method of melting treasures with a large amount of essence blood. It sounds evil, but this method is used by many cultivators in the process of refining treasures, often used to refine some special materials.
But the treasure refining technique on the iron fragment seems to have added a lot of things on the basis of the Blood Refinement method, the biggest difference is that it will use the spirits of demon beasts, even the Nascent Souls of human cultivators, and the souls of desolate beasts. It seems to focus more on condensing these souls.
And the materials used are extremely special, a material called Nether Soul Jade.
This material has been seen in some material classics, it is an extremely top-notch material of Yin and Cold attribute, a small piece of Nether Soul Jade the size of a fist is worth millions of spirit stones, and it is priceless and extremely difficult to find.
The Blood Soul Cauldron in his hand, although it looks only the size of a palm, but this is only the size shrunk by the magic formula, its body is actually a blood cauldron with a diameter of about ten feet.
Just collecting the Nether Soul Jade used to cast this cauldron would take an unknown amount of time, and the spirit stones spent would be even more astronomical.
In addition to this, there are several rare auxiliary materials, which are not ordinary materials, and are not easy to collect.
According to this treasure refining technique, even a force like the Ten Great Sects would not be easy to refine a Blood Cauldron successfully.
The reason why Zhang Ling feels that this treasure refining technique is related to the Blood Soul Cauldron in his hand is because the iron fragment is engraved with a small cauldron pattern exactly the same as the Blood Soul Cauldron.
Moreover, on second thought, the first time he saw this Blood Cauldron was when he was tracking Madam Cao in the Ice Fire Jade Mine. At that time, Madam Cao found the Blood Cauldron on the body of a middle-aged male corpse.
According to Madam Cao's words at the time, that middle-aged man was originally a cultivator of Snow Moon Tower, who had defected, seemingly for this Blood Soul Cauldron.
After that, the middle-aged male corpse suddenly resurrected and turned into a scarlet monster, and the iron fragment was obtained by killing the scarlet monster.
Now that he has deciphered the ancient texts on the iron fragment, Zhang Ling has some understanding in his heart. There is a 90% probability that this Blood Soul Cauldron was refined according to this nameless treasure refining technique.
Could it be related to the Blood Demon Sect, or is Snow Moon Tower itself related to the Blood Demon Sect.
For a time, he had several guesses in his heart.
There must be some secrets he has not discovered in this kind of treasure refined by special methods.
It's just that the treasure refining technique on the iron fragment also seems to be incomplete, there is only the method of casting the Blood Cauldron, but no related introduction. I don't know what magical powers this treasure originally had.
He always felt that this kind of treasure would definitely not be simply used for defense or attack. There may be other wonderful uses that have not been discovered.
After all, this is a treasure that even the Lord of Snow Moon Tower values. It seems that when using this treasure, you must pay special attention.
After Zhang Ling took back the Blood Soul Cauldron, he began to study the secret techniques recorded on the front of the iron fragment, and he was very interested in one of the secret techniques.
