Most of the ordinary storage bags worn by the monk Xiliang are made of the stomach pouch of a demon beast called Sha Tao that lives in the desert. The beast's stomach pouch is born with the ability to spatially, allowing it to eat several times or even dozens of times its own weight, and then it can go without food for several years.

The refiner can use the beast's stomach pouch to make a storage bag with a little processing. As the sand gluttony grows older, the grade increases. The more space it has in the stomach pouch. The larger the internal space, the higher the grade.

Many of the Great Sects raise these monsters to make storage bags. Therefore, although the art of space is a relatively advanced spell, the value of the storage bag is not high.

Since this type of monster has its upper limit to growth, there is also a limit to the highest quality of storage bags. Hence the emergence of high-level space artifacts such as storage bracelets and storage rings.

Storage bracelets and storage rings, because they must be made by some alchemists who have mastered the art of space, are very expensive and rare.

Due to the cheapness of storage bags, there are no low-end storage bracelets and rings that have less space than storage bags. Making such a storage bracelet, the ring is more than worth the loss.

As a result, everything such as storage bracelets and rings must be very high-end. Xiao Ziyang's storage bracelet from Cang Soul is such a rare high-grade storage weapon.

Spirit Beast Tower, Spirit Beast Ring and other magic weapons, because of their special requirements for space structure, the stomach pouch of demon beasts such as Sha Tao cannot be made. Must be crafted with space spells. Therefore, this Spirit Beast Tower, although its internal space is only comparable to that of a low-level storage bag, its value is several times higher than that of a high-level storage bag.

With the guardian monk's decision, a ray of light suddenly erupted from a portal at the bottom of the Spirit Beast Tower. With this ray, two swarthy rectangular boxes appeared in the ashram.

Xiao Ziyang swept his mind carefully, what kind of box is this, it is clearly two coffins, and it is a coffin made of high-grade blue soul wood! On the coffin, there are many magic circle texts densely inscribed.

"Refining corpses!" Xiao Ziyang secretly exclaimed in his heart.

"Refining corpses" is an evil method, which selects the corpses of powerful monks, treats them with special techniques, and then buries them in the place where the yin qi gathers, and above the burial place, inscribes a special magic circle, and slowly tempers the corpse with the yin qi of the earth.

After a few years, the corpse will be transformed into a refined corpse. The stronger the body in front of the corpse, the stronger the refining corpse it transforms. After the corpse refining is completed, you can continue to temper with the qi of the earth yin to increase the strength of the corpse refining.

The coffin made of blue soul wood is the best thing to hold the corpse.

As the monk smashed into the coffin, there was a sound from inside. With a creak, the coffin lid was pushed open from the inside.

As the coffin opened, Xiao Ziyang's divine sense penetrated, "Huh!" What surprised him was that there was not a refined corpse in the coffin, but two very strange people.

They are called human because they do not have a trace of corpse in them, and they are strange because they do not have a trace of life in them, like two living corpses.

After pushing the coffin open, two naked "people" climbed out of the coffin. Their skin was pale and bloodless, and they didn't have a single hair, and they looked terrifying.

Under the monk's control, two strange men came up to him and sat cross-legged across from him.

"Huh!" Xiao Ziyang found that these two strange people, if they removed the weirdness of pale skin and hairlessness, just by looking at their appearance, they actually looked a little like the guardian monk. Just a fold of skin, it seems to be an old man, a face is immature, and he is still a half-grown child.

Puzzled, Xiao Ziyang continued to observe the actions of the two strange people. They opened their mouths wide under the monk's command, and from their mouths spewed out a trace of red smoke.

After a while, two pills the size of pigeon's eggs emitted a crimson glow erupted from the mouths of the two men, and they were grabbed by the monk.

Looking at the movements of the three of them, Xiao Ziyang suddenly shook and froze there. After half a sound, he gritted his teeth and said: "Purgatory Blood Corpse" There was boundless anger in his voice.

Looking at the monk's behavior, Xiao Ziyang finally found the name of this strange zombie from Cang Soulzi's memory.

The method of refining this "Purgatory Blood Corpse" is not difficult, but the conditions for refining this blood corpse are very harsh, and the materials are even more cruel to the point of being outrageous.

The material used to refine this thing must be the blood relatives of the refiner, that is, parents, brothers, and children, and at the same time, the blood relatives who are being refined must have the same spiritual root as the refiner.

This kind of "Purgatory Blood Corpse" has no combat power, in addition to being able to cultivate on their own, their only role is to condense the "Blood Pill".

The "Blood Pill" has no effect on other monks, but for those who are connected to the blood of the blood corpse, have the same spiritual root, and practice the same exercises, it is the best elixir in the world.

The original intention of the "Purgatory Blood Corpse" refining was to assist in cultivation. Using the same bloodline as a guide, a part of the soul is placed in the blood corpse, and then the secret method is used to make the blood corpse maintain the characteristics of some living people, so it can be cultivated.

Because the blood corpse was cultivated under the command of the refiner's soul splitter, the true yuan it cultivated had the soul imprint of the refiner. After that, the blood corpse then used a secret method to condense part of the cultivated true yuan into a "blood pill".

This "Blood Pill" can be absorbed by the refiner without any loss and turned into his own true element mana.

If this is the case, since this blood corpse is not a living person after all, its cultivation speed is very slow, and it will not be able to make this guardian cultivator's cultivation speed faster than that of ordinary Heavenly Spirit Root.

It also has another function, which is to help the monk refine the impurities in the true element of mana. Although the cultivation speed of this blood corpse is very slow, because it has no spiritual intelligence, it is extremely patient to do such a thing that requires a lot of water grinding skills. Therefore, the true element that has been refined by it is absolutely pure, comparable to the true element of the mana of the Heavenly Spirit Root Cultivator.

Because of this characteristic, blood corpse refiners can safely take a large amount of pills to assist in cultivation without fear of erysipelas.

Sure enough, after putting away the two blood pills, the monk took out a bottle of pills from the storage bag, poured out two pills, and then slowly refined them.

Xiao Ziyang also knew this elixir, which was a very common medium-grade elixir for monks in the foundation building period to increase their mana. Generally, monks will only take it when they hit the bottleneck, as well as when they are fighting methods, refining weapons, and alchemy, and their mana is not continuous, and they have no choice but to take it.

Or some monks who know that they can no longer make a breakthrough and give up the possibility of moving forward, will recklessly take a large amount of food.

This person kept taking and refining this kind of medium-grade pill that many monks regarded as poison, and he actually took more than a dozen pills in just over two hours.
