With a "hum", the blood demon instantly became transparent, and Xia Mu could clearly see that in this blood demon's body, there were a total of 128,000 blood vessels, and they were densely packed all over the entire blood demon's body.

Of course, this is not the point, in the center of these blood vessels, a powerful heart is beating slowly, every beat, it is like a volcanic eruption, infinite power swept out, along the 128,000 blood vessels, along the blood to the blood demon's body.

Xia Mu could sense that the blood demon's body in front of him was not strong, it was not even as good as him, and he didn't use any spiritual skills, but every time the blood demon's heart beat, the power generated in it could easily kill him.

For a while, Xia Mu was stunned, although this was not a real teaching of words and deeds, but it was not far off. He stood there, seriously perceiving the various changes in Fang Cai's blood demon's body, constantly imitating, trying, and verifying, and in an instant, Xia Mu blurred the time here, feeling as if only a few seconds had passed, but it seemed like thousands of years had passed.

In this way, he was immersed in the magic of the change of the blood demon's body, and for a while he fell into a deep epiphany, and in the outside world, Xia Mu's body also underwent great changes, wisps of blood overflowed from the blood mark in his body, penetrated into Xia Mu's blood, and then as these blood flowed all over Xia Mu's body, it quietly changed his body.

At this moment, the flow rate of blood in Xia Mu's body became very strange, one would be as slow as a turtle crawling, and the other would be as fast as a jaguar, until a long time, the flow rate of blood in his body gradually became normal.

In the world of blood seals, Xia Mu's body has gradually been submerged in the sea of blood, not that his body has sunk, but that the sea of blood is invisibly and autonomously wrapped towards his soul.

One after another blood-colored runes were mixed in the sea of blood, flying around him, sometimes turning into drops of blood rain, sometimes turning into blood shadows, they were constantly changing, as if interpreting the mystery of the Blood Demon Sutra.

And Xia Mu, who was in a state of enlightenment, naturally couldn't feel this scene, he saw a different scene.

A drop of blood appeared in the misty chaos, the color of this blood Xia Mu couldn't say, it looked bright red blood at this second, but when he looked at it again in the blink of an eye, it turned golden again. And around this drop of blood, wisps of chaotic qi were permeated, all derived from this drop of blood.

It seems to contain the secrets of the chaos of the heavens, and between the color changes, sometimes it turns into a true dragon, sometimes it turns into a heavenly phoenix, and sometimes it turns into other beasts, all of which are the strongest beasts that Xia Mu knows.

The scene was too shocking, just a drop of blood, but it was like the source of all things, containing the supreme mystery of life, the four poles of heaven and earth, and the universe all revolving around it.

During this time, the blood changed color and form, eventually turning into a blood cocoon.

I don't know how long it took, until one day, the blood cocoon suddenly agitated, and then its surface suddenly cracked, and a man came out of it.

The man's eyes are red, and there are endless years passing in the circulation, and wherever his gaze looks, the speed of time will speed up, which seems to be very similar to the legendary great magic power "One Eye Ten Thousand Years".

However, when the man closed his eyes and opened them again, two bloody rays of light shot out of his eyes, and where the blood light passed, even the chaos was annihilated, the big star fell, and the galaxy was cut off, which was unimaginably terrifying.

Xia Mu's heart shook dramatically, is this the Blood Demon?One of the oldest beings born in the chaos, not to mention anything else, that eye light alone was enough to kill the Eternal Saint.

Does such a life really exist in chaos?

Although Xia Mu has seen a lot of big scenes, he is also a little unbelievable, but soon Xia Mu has no time to think about this problem, the sky is spinning, his soul is glowing, the light is blood-colored, and then one by one the blood-colored runes fell down and submerged into his soul.

In an instant, Xia Mu's spirit and will were integrated into these blood-colored runes, absorbing the mysteries of the Blood Demon Sutra contained in them to the fullest, and exploring the law of the Blood Demon.

Gradually, the blood light emitted by his divine soul became more and more brilliant, spilling through his body and overflowing into the body, reflecting the entire cave in a blood-red color.

For a time, the blood was monstrous, mighty, and incomparably strange.

A demon shadow appeared behind Xia Mu, the face of the demon shadow was not real, but it was extremely weird, and the pair of red demon pupils looked at Xia Mu, flashing with faint blood.

In the end, the demon shadow slowly fell, submerged into Xia Mu's body and disappeared.

At this moment, Xia Mu seemed to be incarnated as a blood demon, and in a trance, he felt that every drop of blood in his body was cheering, and in this drop of blood, there was a hidden and magical power, which was very small, but it could be gathered, but it was also very powerful. Xia Mu knew that this was the power hidden in the blood of the human body, and if it could be developed, it would definitely not be underestimated.

Of course, while discovering this power, Xia Mu also discovered some other things contained in his blood, including essence and dross.

Next, the changes continued, and runes began to be derived from the blood in Xia Mu's body, condensing on the walls of his blood vessels, as if wearing a layer of armor.

At this moment, there was a strange aura permeating, the runes derived from the blood were endless, it was difficult to count how many there were, each one was crystal clear, each one corresponded to a drop of blood in Xia Mu's body, and it was slowly merging with it.

That feeling is particularly wonderful, as if the blood in the body is constantly being purified, and the whole person is a lot empty, Xia Mu is immersed in it, feeling the endless secrets hidden in the blood, and gradually forgetting himself. At this moment, he seemed to see the whole process of the birth of that drop of blood in the chaos.

It was the era of the explosion of the entire chaotic life, and a drop of blood was born from the chaos.

At that time, this drop of blood was not as magical as Xia Mu had seen before, it was very ordinary, but it was such an ordinary drop of blood, which continued to evolve in the chaos, and finally transformed into one of the most powerful beings in the chaos, achieving the position of the Ten Thousand Blood Demon Venerable.

Is this the Blood Demon Sutra? Xia Mu sighed, the Blood Demon Sutra is not so much a technique, but rather the growth history of that drop of blood, and its process of transforming from an ordinary drop of blood in the chaos to the strongest life in the chaos is condensed together, and this Blood Demon Sutra is achieved.

Of course, the exercises are exercises, and the blood demon is the blood demon, not that with the Blood Demon Sutra, you can achieve the achievements of the blood demon in the past.

Xia Mu understood that the Blood Demon's ability to achieve such an achievement was inseparable from the general environment at that time, so he immersed himself in it and tried his best to comprehend the fragmentary pictures in the Blood Demon's mind.

In this way, Xia Mu swam in the memory of the blood demon, his mind was isolated from the outside world, and he threw himself into a wonderful situation.

At the same moment, someone approached and came to the cave where he was retreating, and it was the second most successful person on the killing list.

He broke the prohibition that Xia Mu had arranged outside, passed all the way unimpeded, entered the belly of the mountain, and saw Xia Mu sitting cross-legged in the cave.

"Sure enough, there is something wrong with the body!" Looking at Xia Mu, who was not moving, there was a hint of joy in Wuying's eyes, the movement of him breaking the outside formation prohibition was so big that it didn't wake Xia Mu up, you can guess how much trouble Xia Mu encountered at this time.

Wuying made a decisive move, and a pitch-black dagger cut through the void, instantly cutting Xia Mu's throat, but the next moment, Wuying's face changed greatly.

"It doesn't feel right!" The dagger cut into Xia Mu's neck, and there was no feeling of a sharp blade entering the flesh, and in an instant, he understood that Xia Mu in front of him was not the deity at all.

It's a pity that he understood too late, a blur in front of him, "Xia Mu" turned into a water-blue puppet, and under the expansion of his body, he instantly wrapped the shadowless into it, and then with a bang, Xia Mu's water puppet from the true puppet ancestor exploded like this, and even the shadowless in it was blown to the bone.

A generation of geniuses, the second in the killing list of Wu Ying, fell like this, and died under Xia Mu's calculations, leaving only a blood mark.

But soon, this blood mark was brushed and submerged into the ground, passing through the strata for several miles, before coming to another cave and submerging into Xia Mu's body.

And Xia Mu didn't know about this change, although he laid out all kinds of calculations, but he didn't expect that someone would really be able to find here, everything was just a precaution, but he didn't expect to kill Wuying.

"Buzz!"

After devouring the shadowless blood mark, the color of the blood mark in Xia Mu's body gradually turned golden red, and the blood-colored runes in it also changed, turning into a blood-colored villain, swimming in Xia Mu's blood.

"What happened?"

Xia Mu was frightened, opened his eyes, and felt shocked, in the world of blood seals, countless runes converged, and gradually condensed into a drop of blood, from the memory of the blood demon, Xia Mu knew that this drop of blood was the blood of the blood demon, conquering the world and creation.

After a long time, the divinity in the blood has long been wiped out, and the power in it has disappeared, but the true value of this drop of blood is not here.

With this drop of blood, Xia Mu is equivalent to having a guiding light on the road of cultivating the Blood Demon Sutra, how to go in the future, as long as you refer to this drop of blood demon blood, everything will have an answer.

Of course, Xia Mu's comprehension of the Blood Demon Sutra is still superficial, and he can't see the mystery of this drop of blood at all, so he has to come back to understand it in the future when the realm is profound.

This is a big opportunity, but now Xia Mu doesn't have the strength to get it.

When he closed his eyes again, he found that the blood in his body seemed to have changed, becoming more pure and thorough, although it was still blood, but this blood was full of holiness, which made him feel like he was reborn.

In a trance, Xia Mu seemed to have returned to the state where he had just entered the blood refining realm, and that feeling was particularly wonderful.

In the following time, Xia Mu continued to enlighten and memorize the runes of the Blood Demon Sutra, although it was not complete, the existing part of the mysteries was enough for Xia Mu to comprehend for a long time.

"It seems that the realm of blood refining is not simple, and I only touched a little bit of skin at the beginning. Xia Mu muttered to himself.
