The Tao is permanent, but the devil is impermanent.

Different from the orthodox inheritance of the Daomen accepted by Lin Haoyu, the exercises of the Demon Sect do not rely on the Heavenly Dao, but through the development of oneself, to achieve the release of the inner heaven and earth, and thus affect the outside world, so the inheritance of the Demon Sect is not passed on by word of mouth, but through guò's own perception, and through guò's comprehension of others' perceptions to inspire oneself, and finally find one's own way and develop one's own inner world.

When Lin Haoyu accepted the inheritance of the Daomen, Du Aotian followed a guard of the Law Hall to the outside of the Demon Sect's forbidden land to forge demons. Located in the back mountain of Tianzhu Peak, the Demon Forging Cave is a cave that goes straight to the bottom of the earth, and is said to be connected to the center of the earth.

A gust of yin wind blew out from the Demon Forging Cave, even Du Aotian subconsciously shivered, this Demon Forging Cave is not only a place for all the masters in the Demon Sect to retreat, but also a place to punish the disciples who make mistakes, a burst of iron chains came from the cave, mixed with a roar of madness, pain, or remorse, which made people creepy.

Suddenly, a painful roar came out of the Demon Forging Cave, which was an inhuman sound made after the pain exceeded the limit of human physiology, Du Aotian's eyes narrowed, and he took a step forward, and in an instant, a mixture of gloomy, tyrannical, and even tyrannical aura came to his face, and the gloomy aura hidden in it made Du Aotian's protective body Zhenqi move, which barely separated these uncomfortable breaths.

"The place you are going to, on the fifth floor of the Demon Forging Cave, there is a jade tablet, which was left by the seventeenth generation of the Torture Hall Elder back then, and it is the feeling when his inner heaven and earth reached all the outside, which is somewhat helpful to you compared to now. "Behind Du Aotian. A law hall guard said respectfully.

This guard of the Law Hall has a very high cultivation, at least in the middle of Ning Dan. But when facing Du Aotian, he didn't have the slightest arrogance, and he had the support of the elders of the Law Palace. As a subordinate of the Law Palace, he naturally has to respect Du Aotian.

Du Aotian nodded, and asked in a harmonious voice, "Is there any taboo when you enter it?"

"As far as I know, it is divided into seven layers, corresponding to the seven realms of entering the Dao, building the foundation, refining the body, breaking the barrier, turning liquid, condensing pill, and Yuanying. Therefore, I have taught the great powers of the past generations to often come and go here, and have found some suitable places for understanding. The guard said respectfully.

Glancing at Du Aotian's face, the guard continued: "The predecessors I taught the past generations have left their own ways in these places suitable for understanding, and everyone who enters, as long as they have understanding, will also stay for the convenience of their juniors. ”

Du Aotian nodded and said, "You can send me here, I'll go in by myself." ”

The guard was stunned. Nodding yes, watching Du Aotian step into the Demon Forging Cave, his eyes couldn't help but condense slightly, because Du Aotian actually didn't release True Qi. He walked in so plainly, and the pace was constant, as if the yin wind in the Demon Forging Cave could not bring him any influence at all.

There are two possibilities for this situation. The first is that Du Aotian has the ultimate body refining technique, and his physical body has already been tempered to the extreme of this realm, and the second is that his control of Zhenqi has reached a subtle level. It can gather true qi on the surface of the body, condensing but not hairing. Achieve the effect of defense.

As far as he knew, it was almost impossible for him to achieve such a level during the Liquid Transformation Period! At this time, he had the idea that Du Aotian's cultivation was the "Secret Book of the Two Pulses", which was said to be the most difficult to practice.

"This kind of strength, if it suddenly strikes, I'm afraid it will be difficult for me to stop it...... Seed, seed......" The guard muttered in a low voice before turning to leave.

The moment he stepped into the Demon Forging Cave, Du Aotian felt a biting cold, and with a drum, a thin layer of shield was formed outside the body, covering his whole person, which isolated this cold breath, and looked around, only to see that next to the passage, several ragged Demon Sect disciples were tied to the pipa bone by iron ropes and fixed on the pillars next to the passage.

This is only the first layer, and there is nothing left here in the wind of the yin wind underground, so here are also some disciples of the Demon Sect in the Dao stage, and by chance, he saw that there were two white bones on the two pillars, constantly swaying under the blowing of the yin wind, and there was an unspeakable desolation and horror in the loneliness.

"Locked up like this?" Du Aotian shook his head and walked down, along the way, the screams and screams of these errant Demon Sect disciples and the friction of iron chains echoed in his ears repeatedly, most of these people have been tortured by the underground wind to the point of half madness, lost their minds, even if they survive the detention period, they will be wasted for a lifetime if they can get out.

A few sane people were still quite conscious when they saw Du Aotian passing by, and couldn't help but howl loudly: "My lord, I know that I am wrong, let me down, let me down, I can be a cow and a horse for adults in my life......"

The people who were responsible for sending Bigu Dan to these guilty people were all junior disciples wearing special clothes, which could be recognized at a glance, and people like Du Aotian, who entered here alone and wearing regular clothes, were mostly big people who came here to comprehend the "Dao marks" left by the predecessors of the Demon Sect.

Du Aotian didn't pay attention to anyone, but stepped through the first layer of the corridor unhurriedly, and stepped into the second layer, as if passing through an invisible barrier, Du Aotian only felt that the pressure around him instantly increased a lot, and even in the yin wind that blew, the violent and killing aura increased a lot.

Slowly adjusting the strength of the body's true qi, Du Aotian continued to walk inside, this place is still a long way from the fifth layer of the Demon Forging Cave, he carefully sensed the surroundings, and his brows couldn't help but slowly wrinkle.

Although he was able to communicate with heaven and earth during the barrier-breaking period, and absorbed the Heaven and Earth Yuan Qi in his body with 36,000 pores, the Heaven and Earth Yuan Qi in this Demon Forging Cave was really pitiful, and it was simply a fool's dream to get supplements from the outside, and his own recovery power, even if he had dual veins, could not restore the True Qi infinitely.

Now it's only the second layer, and the speed of Zhen Qi's consumption is already approaching half of his recovery speed, but I don't know what the situation will be like in the fifth layer, thinking of this. Du Aotian was ruthless and slowly withdrew the Zhenqi on his body. The yin wind reaches the body, with a little bit of a blade blowing.

"Isn't it just pain? What can compare to the pain of cultivating the Secret Book of the Two Veins?" Du Aotian smiled and took a big stride towards the third layer, the yin wind was getting stronger and stronger, but Du Aotian simply stopped sensing what aura was in these yin winds, and just walked forward.

On the third and fourth floors, when Du Aotian stepped on the boundary between the fourth and fifth layers, he was just in time for a strong wind to blow, and the clothes on his body were instantly blown into pieces of rags by this yin wind!

When Du Aotian stepped into the fifth layer. All visions vanished, and the silence was eerily quiet.

Du Aotian looked at it fixedly, and saw a jade bi in front of him, he walked over, stood in front of the jade bi, and stared at this jade bi.

This jade must be the fate left by his predecessors, he desperately tried to find some differences from above, but the naked eye could not find any vision at all, only a few clear scratches were engraved on the jade. It's not like words, it's like a random sketch of a naughty child.

Stretching out his right hand, Du Aotian gently stroked these crooked scratches, without any trace of Zhenqi or artistic conception. Only the gust of wind blowing from the ground stinged his skin.

Of course, the predecessors of the Demon Sect would not do such a boring deed, since Ma Qingxuan told him where this jade is located, it means. There are already countless people here who have comprehended, Du Aotian took a deep breath. Slowly calm his mind, and then his consciousness comes out. Begin to explore the inner workings of the whole jade.

The moment his divine consciousness touched those few scratches, a murderous aura rushed into contact with his divine consciousness, and a muffled sound came from the void, and even through the whistling yin wind, it spread far away, Du Aotian's face turned pale, and then he returned to normal, but he did not give up, but instead increased the intensity of his divine consciousness and began to further explore the mysteries.

If Yubi reacts, it means that there is no problem with the method of self-enlightenment, as long as you follow this path, you can comprehend it.

With the deepening of Du Aotian's divine consciousness, the murderous aura that confronted his divine consciousness became more and more intense, if the murderous aura encountered at the beginning was just a breeze, the murderous aura encountered now was a murmuring water, and there was a trend of changing towards a huge wave, or even condensing into substance!

However, Du Aotian was not moved, his inner heaven and earth were slowly released, and there was already a cloud of darkness in the Demon Forging Cave, but after Du Aotian released the inner heaven and earth, the original darkness was quickly rejected and replaced by a gray-black light.

The inner heaven and earth slowly expanded, and finally collided with the jade bi, and the moment the inner heaven and earth came into contact with the scratch, the gradually intensifying murderous aura instantly skyrocketed, and Du Aotian only felt a shocking murderous aura gushing out of the scratch, condensing into a substantial sword, and slashing down towards his divine soul!

Du Aotian didn't flinch, his divine soul let out a silent roar, the violent divine soul fluctuations dispersed, and a murderous aura that was also almost substantial poured out of his body, condensed into a Fang Tian painting halberd, and headed towards the sharp sword!

It was obviously an invisible and qualitative murderous aura, or a contest of divine soul power, but at this moment, a sonorous sound broke out that could only be made by the collision of physical weapons, and the yin qi in the void was driven by this blow, and a whirlpool was formed in an instant, with a stream of yin wind blowing on Du Aotian's body.

This time, Du Aotian didn't hold it after all, he suddenly opened his eyes, an abnormal flush flashed on his face, and then a mouthful of blood spurted out, he squinted his eyes and looked at the jade bi in front of him, his eyes were full of solemn looks, because this jade bi didn't seem to have changed even a bit!

"The path of the devil is impermanent, and it is so difficult to even comprehend the experience of the predecessors. Du Aotian smiled a little self-deprecatingly, the True Qi in his body changed from slow to fast, and under the linkage of the internal and external double pulses, the True Qi instantly rushed like a river, and even made bursts of thunder!

Du Aotian knows that now he has encountered resistance, which proves that his general direction is right, but the resistance is so strong, that is, there is a problem in the specific method, and if you want to solve this kind of problem, there are two ways to go, one is to think repeatedly and find the right path;

He is known as the king of heaven, and his cultivation techniques, martial arts and even supernatural powers are related to the word Wang Ba, and he will naturally not back down at this time, after all, even if the predecessors who have realized these truths have a high historical status and a strong final cultivation, they can't get out of the category of the peak of condensate, and what he Du Aotian has to do is to crush a qiē predecessor and reach the height where the true demon is!

With the acceleration of True Qi, Du Aotian's momentum continued to rise, and the almost substantial murderous aura rushed out of his body, his blood, along with his divine soul power, instantly boiled, and under his manipulation, his divine consciousness condensed into a steel knife, and slammed into the jade bi under the murderous aura!

In response to him, it was the same murderous aura that was like substance! (To be continued......)
