The flocculent Taixu cloud fruit exudes a faint fragrance, just a sip of it, it makes people feel refreshed.

Xia Mu immediately threw his palm, and the Taixu Cloud Fruit was bitten by him, and the milky white juice immediately overflowed into his mouth.

Then only a "grunt" was heard, and when the juice was absorbed by Xia Mu, the remaining flesh was swallowed directly by Xia Mu into his abdomen, and suddenly a stream of heat spread out in his internal organs.

After a few breaths, a stream of green qi began to surge upward, straight into the Mud Pill Palace, instantly making Xia Mu's head feel almost full.

Xia Mu knew that this was due to the excessive medicinal power, so he did not panic, but kept his mind calm and worked hard to refine this green qi that appeared in the Mud Pill Palace.

After refining for about half an hour, Xia Mu refined part of the medicinal power of the Taixu Cloud Fruit, and his mind was clear for a while, making him feel good, and he had a feeling that the world was completely new.

At the same time, the power of his divine soul has also been condensed a little, although there has been no qualitative change, but it has also made Xia Mu very satisfied, the medicinal power of the Taixu Cloud Fruit is still about thirty percent accumulated in his mud pill palace, if it is all refined, the power of the divine soul will be condensed a little more.

In this way, in the face of the coercive impact of the Immortal Habitat, Xia Mu was much more sure of resisting.

Of course, these are all precautions, after all, he is now in the Fifth Heaven Battlefield, and all the Immortal Realm monks he met have cultivated to be suppressed in the Five Elements Great Perfection Realm, in this case, don't say anything about the coercion of the Immortal Realm, even the Cave Heaven World that he has cultivated by himself cannot be opened, so it is said that the Immortal Realm monks who enter the battlefield below the Seventh Heaven are the weakest, and they are easy to capsize in the gutter and be killed by the powerful Five Elements Realm monks.

Even the powerhouses of the Demon Killing General would not easily let the deity enter the battlefield below the Seventh Heaven, not because he didn't dare, but because he didn't want to take that risk.

After resting for a while, Xia Mu waved his palm, and a large seal and a set of cyan array flags appeared in his hands.

These two spirit treasures were obtained by Xia Mu from the person suspected of being in the water prison in the depths of the abyss of the blue sea, and they are both acquired medium-grade spirit treasures, among which the treasure spirit is still very weak, and he can't even do the most basic idea communication, and he doesn't know if he was born so weak, or because he has existed for too long, the spirit of Bao Ling has degraded too much.

But even so, these two spirit treasures are still very powerful, and it is good to use them against the enemy after a little sacrifice.

Thinking so in his heart, Xia Mu's gaze first fell on the big seal, opened his mouth and spit out a red flame to wrap it, and then the ten fingers were linked, and one by one the seals were formed, combined into a door control system, imprinted into the big seal, and slowly refined.

With the imprint of the prohibition, a circle of earthy yellow dazzling eyes suddenly lit up on the big seal, and then it turned around, and instantly became much heavier, and when it fell into Xia Mu's hands, he almost couldn't hold it.

Putting away the big seal, Xia Mu raised his hand and released the crimson flame to refine the set of cyan array flags again, this time, it took Xia Mu half an hour to refine it, mainly because this set of cyan array flags had a total of sixteen poles, and it took so much time to refine them.

After refining the cyan array flag, Xia Mu began to silently think about the blood demon secret technique he was going to cultivate next.

He still remembered that when he fought with Yang Kong, the other party was obviously relieved when he heard that he had not refined that drop of blood demon's blood.

This shows that the other party is very jealous of Xia Mu's refining of that drop of blood demon blood, but as far as Xia Mu knows, there is no more powerful secret method in the first two layers of the Blood Demon Sutra, but there is a relatively special technique in the third layer of the Blood Demon Sutra, called Blood Sacrifice.

This exercise requires the cultivator to extract a part of his own essence blood to condense the blood pool, and after the blood pool is condensed, the powerful blood between heaven and earth is collected and stored in it, forming a special blood bank, which is usually hidden in the fetal palace.

If you encounter a strong enemy, you can start the blood sacrifice secret technique in an instant, using the blood stored in the blood pool in advance as a sacrifice to sacrifice yourself in exchange for the powerful power of the blood demon.

This secret technique looks no different from a secret method that temporarily enhances combat power such as the Transformation Battle, but since the blood pool was condensed in advance and sacrifices were prepared, there would be no hidden dangers even after the secret technique was cast. Of course, if the battle is not over before the blood of the sacrifices prepared is exhausted, that is another story.

As for the power of the blood demon that can be exchanged for the blood sacrifice technique, it is related to the level of the sacrificial blood and the cultivator's own will.

According to the classics, the higher the level of the sacrificial blood, the more blood demon power will be exchanged after the sacrifice, but if the cultivator does not take into account his own will and forcibly exchange as much blood demon power as he can, then when the blood demon power is infused into the body, because he can't withstand the impact of the blood demon's intent, it may cause the caster to go crazy and become a crazy person who only knows how to kill, so in addition to finding high-level blood in cultivating this technique, whether his own will is strong is also a very critical element.

If one's own will is strong enough, then theoretically, as long as the blood of the sacrifice is high enough, then it can be exchanged for more and more powerful blood demon power.

In addition, if the monk is unable to find the strong blood, or if the blood in the blood pool has not ended the battle after the blood has burned out, he can also sacrifice his own blood.

It's just that doing so will cause the monk to lose a lot of vitality, and it will take a long time to recuperate.

In this way, after carefully studying and comprehending the secret technique of "Blood Sacrifice" for several hours, Xia Mu withdrew his mind from the blood demon seal in his body, and then took out an acquired long sword with a flip of his palm, and withdrew his own defense, and then held the spirit sword and infused it with spiritual power to cut a wound on his index finger and finger, and urged the Blood Demon Sutra to force out the blood in his body.

After more than a dozen breaths, the blood that was forced out of Xia Mu's body was already the size of a fist, and under the control of his spiritual power, it condensed into an embryo of a blood pool in the blood air.

After doing all this, Xia Mu followed the condensation method of the blood pool, and raised his hand to punch out the blood pool embryo, and suddenly the blood pool embryo began to change in the void, first turning into a boxy blood pool, and then on the four corners of the square blood pool, the blood condensed and turned into a vague humanoid statue.

At the same time, in the center of the blood pool, a quaint blood-colored altar slowly took shape, and at the top of this blood-colored altar, there was a bowl-shaped vessel, which seemed to be specially used to hold the blood used for sacrifice.

At this moment, Xia Mu recited a long list of strange mantras like sacrificial texts, and after reciting them, he opened his mouth again, and the blood light rolled, and he swallowed the blood pool into his stomach with a whoosh.

Afterwards, Xia Mu only felt a stirring in the Fetal Palace Spirit Lake, and then the blood pool appeared above the Fetal Palace Spirit Lake out of thin air, and continued to absorb the spiritual power in the Spirit Lake below.

On the surface of the blood pool, wisps of blood are swirling, as if the most ingenious craftsman in the world is constantly carving the blood pool with spiritual power as the material.

Xia Mu's mind moved, and he released a wisp of divine thought to communicate with the blood pool, but the latter was like a stone sinking into the sea, and there was no response.

In this way, in the next few days, Xia Mu would continue to condense the blood pool with his own essence blood every day, and refine the forbidden ones into it through secret techniques.

After about six or seven days of this process, the blood pool above the Naling Lake also quietly changed, becoming a little more refined than before.

On this day, Xia Mu's eyes opened and he woke up from the cultivation of the condensing blood pool, and then raised his hands and began to seal quickly, and at the same time, he spat out a light "sacrifice!" in his mouth.

Suddenly, there was an inaudible humming sound in the fetal palace, and then part of the essence blood in Xia Mu's body was absorbed by the blood pool, accompanied by a burst of blood light, only to see that on the top of the central altar of the blood pool, a wisp of blood gas slowly condensed out, and entrenched in the bowl-shaped vessel at the top of the altar.

"Isn't it, I only condensed such a wisp of blood by spending dozens of drops of my own essence blood?" Looking at the wisp of blood entrenched on the top of the altar, Xia Mu was speechless.

In addition to condensing the blood pool, the development of the Blood Burning Secret Technique also requires the sacrificial blood sacrifice, and this blood sacrifice is the blood of the creatures of heaven and earth.

Because he couldn't figure out the approximate standard of the blood sacrifice, Xia Mu used part of his own essence blood as the experimental object, and as a result, this refining could be condensed into a wisp of blood qi.

Such a wisp of blood qi could not meet the standard of the Blood Burning Secret Technique, according to Xia Mu's speculation, even if he used all the essence blood in his body to condense it into a blood sacrifice object, it might not be able to meet the requirements of performing a Blood Sacrifice Secret Technique.

After pondering for a moment, Xia Mu touched his eyebrows, there was still a drop of blood demon blood sealed, which had not been effectively used, and now Xia Mu's cultivation of the secret technique of blood sacrifice had just begun, but it could be used to refine it into a blood sacrifice thing.

Thinking about it like this, Xia Mu fought the law in his hand, and the blood of the blood demon that was originally hidden in the center of his eyebrows took the initiative to fall into the blood pool.

The next moment, the entire blood pool began to tremble wildly, and then a large amount of blood began to be derived from the originally empty blood pool, and in just a few blinks of an eye, the blood pool was filled with a large amount of blood, and at this time, the blood of the blood demon was only a tenth of the consumption.

This made Xia Mu both surprised and a little depressed.

The surprise was that for a long time in the future, he didn't need to bother with the sacrifices of the Blood Sacrifice Secret Technique, and his frustration was because he had only condensed a wisp of blood qi after consuming dozens of drops of essence blood, and that drop of blood demon blood only consumed one-tenth of it, refining a whole pool of blood sacrifices that could be sacrificed.

This gap is really not ordinarily large.

"How can I say that I am also a powerhouse with the combat power of the Immortal Five Heavens, why is my blood so different from the blood of that blood demon?" Xia Mu muttered to himself.

At this moment, the Qiankun ring that he had been wearing on his left hand had a buzzing sound, seeing this, Xia Mu's heart moved, and a messenger talisman appeared in his hand, which was the messenger talisman he had given to Changli before.
