Sheng Gray's eyes darkened, and that familiar feeling followed, and he came to that black space again.

This is the second time since the last time I was in the East Post of the Mountain, I have successfully entered here.

Sheng Shen followed his intuition and walked "forward", maybe it was just a moment, or maybe a long time had passed, Sheng Shen appeared in front of his eyes again, and he appeared in Xiao Lei's appearance again, as if it appeared suddenly, and as if it was already there, quietly, there was no reaction to his appearance at all, and a little closer, it was the content of those Taoist scriptures, which Sheng Shen could recite backwards.

And "not far away" from Xiao Lei, it is gloomy, dark and gloomy Xiao Hei.

The reason why Sheng Shen chose to come here as soon as possible was because when he was fighting against that black qi just now, after that black qi entered his body, it directly invaded his flesh and blood meridians, intending to go towards his heart veins.

In the midst of the black air, Sheng Shen felt a strong dark power, with corruption, chaos, and obvious erosion.

If he allowed the black qi to burst into his heart, he couldn't imagine what would happen.

Perhaps, it is very likely that he will be like the baby boy, possessed by black qi, control his mind and body, and become a puppet of black qi.

Sheng Shen would never sit idly by and watch such a thing happen, although he let the black qi successfully invade his body, he did not have the slightest panic, he was extremely calm and calm, and the mana in his body also rose in an instant with his mind, heading towards the black qi.

Sheng Ash has an intuition, mana, it is likely to be able to restrain this black gas, Gain, when the black gas just invaded his body, the mana actually had an independent response, wanting to expel the black gas, but first, without Sheng Ash's active invocation, the distribution of mana is relatively broad, and it cannot be concentrated, so it is not the opponent of black gas.

Second, the instantaneous autonomy of mana, Sheng Shen could feel that in dealing with this black qi, mana seemed to have a strong sense of urgency.

Of course, this feeling is just a description, it just shows that mana has a great resistance to the invasion of black qi, so it must be very restrictive.

But at this moment, from his body, a force suddenly and inexplicably appeared, and the target of this force was also that black qi.

Sheng was shocked and shocked, he found that after the appearance of this force, the mobilization of mana in his body was completely suppressed, and he could not use mana to deal with that black qi at all, and the most terrible thing was that this mysterious power was not under his control at all.

But fortunately, this force did not want to be his enemy, and after it appeared, it directly enveloped the black qi and produced a tearing and shattering force on it.

The black gas immediately sensed that something was wrong, but its own strength was really a little small, after being coerced by that mysterious force, it was impossible to escape at all, the two sides fought, maybe it was a little inappropriate to say that the battle was a little inappropriate, it should be said that the mysterious power completely crushed the black gas, and after it was exhausted, it disappeared.

And this process, manifested outside Sheng Gray's body, is what Lord Xuan Yu once saw, the constantly changing face of the black qi, the extremely painful appearance, is actually the external embodiment of the black qi trying to escape but can't escape.

It was at this time that Sheng Shen inexplicably knew that this power was brought by Xiao Hei, and Xiao Hei conveyed a clear idea to him, asking him to see it once as soon as possible.

Sheng Shen didn't dare to slack off, this was the first time Xiao Hei had reacted since he found out, and it was such a clear and unusual reaction, he really wanted to know what had happened just now.

Sheng Gray approached some Xiao Hei, Xiao Hei's appearance, from a distance, looks like a seed condensed by black mist, but if you look close to a certain extent, you will find that where is this seed, there is nothing.

As the literal meaning of this sentence is, Xiao Hei has completely merged with the darkness around him, and the closer he gets, the more he will find that there seems to be nothing here at all, whether he looks at it with the naked eye or senses it with his heart.

Xiao Hei's voice suddenly came, this voice sounded a little similar to Xiao Lei's, they were all neutral, they couldn't distinguish between men and women at all, but they were slightly lower than Xiao Lei's.

Sheng Shen listened with his ears pricked up, and Xiao Hei said unhurriedly, it was talking about an exercise, called "Yuan Demon Sutra".

After listening carefully to the "Yuan Demon Sutra", Sheng Shen slowly had some understanding of this matter.

It is stated in the Yuan Demon Sutra that the heaven and the earth are first opened, the clear qi rises, the turbidity descends, the pure spiritual qi grows over time, the essence is born, and between the heaven and the earth, there are gradually spiritual things born.

And the filthy breath, over time, also produces essence, is for the demons, essence and incarnation, with spiritual sense, between heaven and earth, there are gradually monsters born.

Although turbidity is the two poles between heaven and earth, most of the places between heaven and earth are coexisting in them, regardless of you and me, and together constitute the foundation of this world.

Different from what he imagined, the Yuan Demon Sutra is a body forging exercise, which tells how to use turbidity to transform demons, return to the origin of demons, obtain demon source crystals, and forge oneself, and the ultimate goal is to achieve the body of the Yuan Demon.

What is the Yuan Demon, Xiao Hei did not elaborate, but explained that this exercise is based on the turbidity of heaven and earth, the essence of the turbidity as the material, and the essence of the demon as the core, to forge the body of the Yuan Demon.

After the exercise was explained, Sheng Shen also solved an important doubt before, that is, in the process of clearing and removing turbidity through the Tao Sutra, the turbidity that should have been excluded from the body disappeared inexplicably, and he never understood it, but now he finally knows, it turned out that it was put away by Xiao Hei, and the battle just now was used in a key place.

In Xiao Hei's narration, that black gas is called demonic qi by Xiao Hei.

After the Yuan Demon Sutra was finished, around Xiao Hei, a black crystal was produced, only the size of a baby's fingernail, this crystal showed a triangular shape, except for black light, there was no other color, its black, and Xiao Hei's black, quite similar, but, it was a little bit less meaningful.

Although Xiao Hei didn't speak, Sheng Shen instantly understood that this crystal was the Demon Source Crystal that had been refined by the Yuan Demon Sutra, but in an instant, the crystal disappeared.

Sheng Shen knew that the Demon Source Crystal he saw was just a phantom.

At the same moment, Sheng Shen felt that something seemed to have entered his bones, and a tingling sensation suddenly hit.

Sheng Shen gritted his teeth, and according to the Yuan Demon Sutra, he refined, decomposed, absorbed, and integrated this crystal into the bone marrow.

Maybe it was because there were too few magic source crystals, and the whole process was very fast, and it didn't take long for it to end.

Sheng Shen let out a long sigh of relief, he opened his eyes, stood up, and moved around twice at will, finding that the discomfort caused by the invasion of demonic qi before had not only completely disappeared, but also that he was now feeling refreshed, and the spirit of the whole person had reached the most perfect state he could achieve at present.

However, Sheng Shen didn't look very happy, and he didn't rush out, but between his eyebrows, there was a little more worry.

When he withdrew from the black space just now, Xiao Hei "said" a few more words, which was still about the Yuan Demon Sutra.

The main thing is to point out that the first stage of cultivating the Yuan Demon Sutra is called Bone Change.

At the beginning of this stage, he successfully refined the first Demon Source Crystal, and then successfully integrated it into the bone marrow to completely change the bone composition, and he had already completed this step.

And the end of the first stage is when you look inward, and all the white bones in the whole body turn black.

On this point, Xiao Hei only talked about this, and Xiao Hei did not mention what the second stage was, how it should begin, and how it should end.

In addition, Sheng Gray is a little uncertain.

Just now, he seemed to feel that Xiao Hei was urging him a little, wanting him to use the speed as soon as possible to refine enough demonic qi to complete the first step of bone change.

The reason why Sheng Shen felt uncertain was because Xiao Lei had never had emotional expressions such as "urging" since he appeared, so Sheng Shen was not sure if his feelings were real.

If he hadn't had some memories of this feeling now, he would have denied himself a long time ago.

In his heart, he actually tends to be an illusion of himself, but even if it is not an illusion, it is not a bad thing for him, does this mean that Xiao Hei is also like what is said in the Yuan Demon Sutra, with a spirit, if this is the case, he can have one more "person" who can speak in the future.

But this is also what he is sorrowful about.

No matter why Xiao Hei wanted him to complete the stage of bone change quickly, but if he wanted to be fast, he had to "eat" a lot of demonic energy, this amount, just thinking about it, Sheng Shen felt a little like giving up.

After eating it, Sheng Ash found that he really loved and hated this word, and when he ate barbecue, he was naturally comfortable, but when he thought of the amount of demonic qi to be eaten by changing bones, the number of "natal swords" to be eaten by breaking iron bars, and the number of days it took for the 88,000 pores of the whole body to synchronize the breathing method.

Oh my God, Sheng Shen felt that not fainting on the spot was already the ultimate embodiment of strong willpower.

This mass of demonic qi refined today, looking at the appearance of the jade master, it seems that he doesn't know what this thing is, from which it can be inferred that this thing is probably not so common, and things are rare and expensive, I don't know if this thing can be bought, but even if it can be bought, I'm afraid it is worth a lot of money, and he is a poor ghost.

Yes, he doesn't know how much he can buy compared to the huge amount of demonic energy he needs.

Besides, whether this thing can be bought or not, and whether there is a place to sell it, is not certain.

Alas, sorrowful, who said that the young man didn't know what it was like to be sad, Sheng Shen felt that he was already about to be white.
