The demons of the mind are formless and substantial, and they can only manifest their images in the illusion of the mind.

Just after Lu Wu seemed to be exhausted, the heart demon came behind Lu Wu silently.

Then, suddenly, he manifested himself in the form of a magic sword.

This magic knife is white and bone-bound, but the cold blade is countless blood light, and countless souls are cast, the sword light is like blood, blazing and cold, and there seems to be infinite resentment entangled, there is a blood-red magic pupil on the knife body, the vision is far-reaching and endless, and it seems to be able to swallow all the mental consciousness.

This knife has a name, called the Heavenly Demon Blood Knife.

Of course, the heart demon only simulated the appearance and breath of the Heavenly Demon Blood God Knife, and it did not even have one-ten-thousandth of the power of the Heavenly Demon Blood God Knife, so it was called the Heavenly Demon Blood Knife.

The Heavenly Demon Blood God Knife once shined in the battle of the gods, and in the hands of the seven generals Yu Hua, he even injured Nezha and Yang Jian and other two great gods, which shows that its power is extremely strong.

Dan furnace has exercised, and the fire has been labored.

After the aura, the first wonderful, yin and yang outside the support.

Through the armor of the Yuan Shen mourned, there was no life.

Whoever encounters this knife will have blood under his eyes.

Although the Heavenly Demon Blood Knife evolved by the Heart Demon did not have one-ten-thousandth of the power of the True Blood Transformation Divine Knife, Lu Wu did not have the mana and supernatural powers of great gods like Yang Jian and Nezha.

Therefore, as soon as this magic knife appeared, Lu Wu felt a cold aura coming from behind him, and involuntarily hit a spirit.

Before Lu Wu could take precautions, he saw that the magic knife was inserted into Lu Wu's mental body like lightning.

I saw that the magic knife pierced Lu Wu's body with a bang, and then emitted infinite suction, sucking all of Lu Wu's mental body into the magic knife.

Then, Lu Wu's body shattered like glass and turned into nothingness, and at the same time, the black gas also shattered like foam.

After Lu Wu's body was shattered, the Heavenly Demon Blood Knife shook in the wind, and it turned into a human form, looking carefully, the face and body shape were exactly the same as Lu Wu, but this Lu Wu was wearing a set of blood-red robes, which was transformed by the demons in his heart.

I saw this blood-robed Lu Wu smirking proudly at this time: "Stupid human beings, boring feelings, they should be enslaved by my Heavenly Demon Clan by nature, and now should be the time for me to enjoy this beautiful world, Lu Wu, don't worry, I will take care of your beautiful fiancée for you, hahaha." ”

The blood-robed Lu Wu was getting an opinion, and he didn't notice why Lu Wu's mind was broken, and why the environment here was not disappearing, but was quietly changing.

Above his head, a stream of starlight silently filled the surroundings of the blood-robed Lu Wu, gradually forming chains towards the blood-robed Lu Wu.

And underground, five miniature mountain ranges are sealed in all directions according to the direction of the five elements.

Finally, the blood-robed Lu Wu sensed that something was wrong, and without thinking about it, he turned into a heavenly demon and turned into a blood knife and was about to escape into the void.

It's just that Starlight suddenly made a big move, and the starlight chains locked the void, leaving the demons in their hearts unavoidable.

The inner demon didn't have time to scold Lu Wu for being cunning, so he turned the blade and plunged straight into the ground, but there were five peaks underground that forbade the five elements, and he couldn't escape into it.

Moreover, the starlight chain and the five mountain peaks are still approaching, forming a trend of crushing the heaven and earth up and down.

This formation was an exploration by Lu Wu, and after getting the Celestial Star Map, he had an idea in his heart.

The five mountains are the earth, the stars are the sky, the five elements are covered, the ten directions are sealed, the stars are united, and the heaven and the earth are netted.

In Lu Wu's thoughts, this is his own Yuanshen Dao, Zhengtianxing and Wuyue Yuanshen, Tianxing Yan Sanhua, Wuyue into five qi, and the way of Daluo can be achieved.

Because the mental illusion is transformed by Lu Wu's own mental power, Lu Wu can arbitrarily verify his thoughts.

The demons of the heart became the test subjects.

The Starlight Chain and the Wuyue Mountain Peak got closer and closer, and although the Heavenly Demon Blood Knife transformed by the heart demon repeatedly escaped and dodged, and tried to pierce the void, it escaped.

However, the void was sealed by the starlight chain at this time, and the demons in their hearts were only in vain.

Seeing that the Heavenly Demon Blood God Knife transformed by the Heart Demon was suppressed in the air and could no longer move, the Heart Demon finally couldn't help but speak: "Lu Wu, haven't you been devoured by me, and where did you get the power of the Heart God from. ”

When Lu Wu heard this, he smiled lightly: "I just hid most of the power of the mind, where did you get the confidence to confirm that you have completely devoured my mind power?"

The heart demon shouted: "Cunning human beings, no wonder the clansmen say that you humans are more cunning and treacherous than our Heavenly Demon Clan, I didn't believe it in the past, it seems that I was careless, and I underestimated you, but, Lu Wu, don't be complacent, I will give you this Heavenly Demon Seed, and we will see each other again in the future." ”

After speaking, an invisible fluctuation suddenly came from the heart demon's body, and the momentum of the Heaven and Earth Net composed of the Starlight Chain and the Five Mountains Divine Peak was not suppressed.

After the invisible fluctuation disappeared, there was only the magic knife left in its place, but it no longer had the meaning of agility, as if it were a dead thing.

Lu Wu pondered for a moment, it is rumored that the Heavenly Demon Clan has the Heavenly Demon Disintegration Dafa, and they can escape in a desperate situation, it seems that this is it.

Lu Wu took the magic knife over.

Entering the cold hand, there is a faint demonic intent that wants to deeply invade Dye Lu Wu, and it seems that he still wants to struggle out.

Lu Wu snorted coldly, and the astral divine light locked on this magic knife.

This magic knife is actually not a physical object, but a thought, slaughtering sentient beings, turning blood into essence, strengthening one's body, and taking the path of killing, which should be the method passed down by the great god of the legendary sea of blood.

Although this is the way of the Demon Dao, some of the methods are also very subtle, and they may not be able to learn from them, such as this Heavenly Demon Disintegration Dafa is good, although the cost is large, but at least it can save your life, and if you can keep your life, you can get up, and if your life is gone, there will be nothing, and you can't help it.

This magic knife is actually a Heavenly Demon Seed, which is a treasure in itself, which can be used to refine some demonic treasures, such as the Immortal God and Demon, Hercules Demon, Six Desires Heavenly Demon, etc., which is a good treasure for refining the demon.

In the "Introduction to the Basics of Western Demon Cultivation", there is a method of refining gods and demons, called the Phaseless Heavenly Demon.

It is recorded: There is no phase of the heavenly devil, there is no trace, there is no trace, there is no trace, the demon is born with the heart, the demon is from the mind, unpredictable, unpredictable, random change, such as electric induction, bad people do.

The Phaseless Heavenly Demon can be said to be the most upper-level demon, but most ordinary cultivators summon the Heavenly Demon from the Void Desire Realm to refine, but this method is equivalent to crossing the Heavenly Demon Tribulation, the danger coefficient is extremely high, and it is easy to be counterattacked.

Therefore, it can be said that Lu Wu can get this Heavenly Demon Seed by chance, otherwise, with the ability of Heavenly Demon to come and go without a trace, it is difficult to get this Heavenly Demon Seed.

Lu Wu temporarily collected this Heavenly Demon Seed in the Heavenly Star Chart, and he was trapped by the power of the stars, and he was not afraid of this Heavenly Demon Seed rebelling.

Because this is not the best time to refine the Phaseless Heavenly Demon, there is still a god waiting to deal with it outside.

Lu Wu survived the inner demon tribulation at this time, and he no longer had any doubts about the path to achieving Jindan.

Although it seems that a long time has been spent in the mental illusion, it is only a moment of effort outside.

Therefore, Zhang Changsheng looked left and right and didn't wait for Akagi-kun to come to help, but waited until Lu Wu opened his eyes, and his gaze was like lightning shining directly on him.
