When the Yuquan Fairy was refining the demon soul, he also knew the origin of this soul through residual memories!

About 8,000 years ago, a demon-dyed monk in the Nine Shadows of Cangwu Immortal Continent was promoted to the seventh order, and as soon as he broke through, he devoured blood and food to strengthen himself, and even the true immortals of the Ancient Demon Palace couldn't look at it, after all, the people in this Dao just wanted to follow the demons to complete the transformation of their own life forms and cultivate into true immortals, rather than becoming the resources of demons, so they gathered the other three true immortals and worked together to kill this great heavenly demon.

However, like Chunyangzi, this demon performed the Heavenly Demon Disintegration Technique before he died, turning his own essence and divine origin into hundreds of millions of demon souls, scattered all over the fairy world, one of which penetrated into Fulong Zhenjun's body, and at the beginning guided Fulong Zhenjun with the face of the remnant soul of the great monk, helping him cultivate step by step to the realm of no phase to the human realm.

And with the continuous improvement of Taoism, Fulong Zhenjun also sensed the essence of the demon soul, but at that time, he had been with the demon soul for nearly two thousand years, and his thoughts had been affected by the demon soul, so he finally chose to believe in this demon soul and chose to keep it secret.

Later, Fulong Zhenjun was reincarnated as a silver-haired boy and re-embarked on the immortal road, and this demon soul also made great efforts, but unfortunately it didn't have a good heart from the beginning, and just wanted to be reborn through Fulong Zhenjun.

In order to prevent the host from falling again and delaying its resurrection process, it will only take action when the silver-haired boy encounters a life and death crisis, and when facing the attack of the Immortal Demon Lord, he also had to expose his traces in front of Shen Mo and others.

But the battle with the Immortal Demon Lord damaged the origin, and it wasn't until the silver-haired boy was captured by the Yuquan Fairy that this demon soul woke up from the silence under the strong crisis stimulation, but it was too late at this time.

"No wonder ......"

Hearing what the Yuquan Fairy said, Shen Mo's face showed a hint of abruptness.

The silver-haired boy was suppressed by Kang Yan, the ancestor of the Kang family, and the companion demon soul did not appear, nor did it affect the silver-haired boy's mind to let him escape from Yuquan Mountain, it turned out that the companion demon soul fell into silence.

However, he soon put this matter behind him, and then issued a decree to the high-level of the Chiyan Sect through the gecko fake body, asking them to pay more attention to the immortal customs of Wulong Mountain, and once they found that there were signs that a living being was parasitized by the remnant soul of Pure Yangzi, they would immediately report it!

Although there was an Earth Yuan Absolute Array to intercept it, there were still 300 million demon souls scattered all over the fairy realm with the fragments of the Demon Nest.

And now that there are tens of billions of immortal cultivators in Wulong Mountain, maybe someone has become the host of the demon soul, which is also a hidden danger...... Of course, the demon soul of Pure Yangzi could not break through the Qingyun Cave Heaven, because the disciples and mortals of the Cave Heaven were not at risk of being parasitized, and it was necessary to pay attention to the creatures outside the Cave Heaven.

With the cultivation of Yuan Heming and other high-level sects, even if an abnormality is discovered, it is impossible to determine who is parasitic for the demon soul, and Shen Mo has to go out in person.

This matter is not very urgent, after all, the scattered demon souls of Pure Yangzi are not too strong, they can only be parasitic on mortals and low-level cultivators, and if you want to cultivate enough to threaten Shen Mo, you will have to spend at least two or three thousand years of hard work!

After drinking spirit wine with the Yuquan Fairy for two days, Shen Mo said goodbye and left, and began the drudgery of moving the fairy mountain again.

After this battle, hundreds of millions of heavenly demons in the western part of Dongjiezhou died, and the remaining heavenly demons did not have the existence of the seventh order, so there was no need to worry, but the demonic origin that escaped had to be refined, otherwise it would still be able to pollute this heaven and earth after a long time, and re-give birth to a demon nest that could give birth to heavenly demons!

Therefore, the Earth Yuan Absolute Array had to continue to be arranged, and it was necessary to make up the number of seventy-two Earth Demons, and then the Great Array could cover the entire Demon Domain, refining the remaining Heavenly Demons and Demon Demon Origins.

In the battle between the two sides, in addition to the nine medium-grade immortal mountains in the array, the remaining low-grade immortal mountains were destroyed by Pure Yangzi, and a total of sixty-three had to be moved, while Shen Mo had already moved six immortal mountains before, and there were still twenty-four to complete the agreement with the Golden Light Dao Chief.

After that, Shen Mo spent another three years moving low-grade immortal mountains from all over the western part of Dongjiezhou, and successfully obtained the formation map of the Diyuan Absolute Formation from the hands of the Jinguang Dao Chief.

As for the remaining thirty-nine, they were left to the Yuquan Fairies, and when they almost recovered from their injuries, they would move from elsewhere to the Immortal Mountain to complete the big array, after all, for them, if they can earn a little more merit, they will earn a little more!

……

"Fairy, I'll go back to Fenglin Continent first. After this matter, I will fly with you again! ”

In addition to arranging the Diyuan Absolute Formation to clear the origin of the demons in the western part of Dongjiezhou, the Yuquan Fairy and the others are also preparing to perform a secret method of immortal arts, to see if they can collect and kill all the 300 million demon souls scattered all over the place through the remnant souls left by Pure Yangzi, so they will stay here for a while longer.

After saying goodbye to her, Shen Mo cast [Reversing Yin and Yang] to switch the true and false bodies.

In the blink of an eye, his qi began to become weak, and then he nodded at the Yuquan Fairy with a smile, and a raging fire ignited on his body, burning the fake body into wisps of green smoke, leaving no trace of the essence and divine origin behind.

After Shen Mo returned to the Qingyun Cave Heaven, he did not immediately arrange the Earth Yuan Absolute Array, but improved and refined the Bone Viewing Treasure Mirror.

In the primordial realm, the four major immortal sects of the Red Flame Domain and various forces, in order to deal with the invasion of the Heavenly Demon Realm, refined a lot of bone viewing treasure mirrors, which could illuminate the demon-dyed monks hiding in the crowd.

It's just that the seventh-order Great Heavenly Demon Demon Soul is parasitic, and it will not immediately demonize the host, but will hide in its soul and form a symbiotic relationship with it, and when the host has achieved something, it will demonize its Dao Fruit, which is even more secretive and difficult to prevent.

At present, the Bone Viewing Treasure Mirror, which is the highest grade of the Red Flame Sect, cannot illuminate the creatures parasitized by the demon soul.

Shen Mo is also not good at casting the Divine Soul Spell on the tens of billions of mortal monks in Wulong Mountain, and it is even more fantastical to use [Insight of Sentient Beings] to check the past one by one, so he thought about improving the spiritual effect of the Bone Viewing Treasure Mirror!

The reason why the Bone Treasure Mirror can illuminate the demon-dyed monk is because no matter how well the demon-dyed monk's appearance is disguised, the internal organs, meridians, and flesh have changed, and the treasure mirror magic weapon can detect the abnormality in it, so as to distinguish which are normal immortals and which are demon-dyed monks.

However, this artifact does not involve the contemplation of the divine soul, so it is impossible to find the host who has been sent by the soul of the Great Heavenly Demon.

As long as the corresponding effect is added on the basis of the original, this is not too difficult for Shen Mo, it only took half a day to improve the Bone Observation Treasure Mirror by changing the internal runes, which can roughly detect the abnormality of the soul, if the person who is illuminated has one more soul than ordinary people, the treasure mirror will bloom with blood light to warn.

"Feng'er, you will send this Bone Viewing Treasure Mirror and the refining method to the Forging Hall, let them put aside the task at hand, and refine a batch of new treasure mirrors as soon as possible in order to screen the Demon Soul Host!"

After Qian Xiaofeng returned from Xuanyuan Mountain, he did not go out to practice again, but stayed in the Spirit Void Domain to practice, and Shen Mo was not ready to go out in the short term, so he called her to the Guanyun Mansion to teach the way of the Divine Bridge, and he could send one or two things to do anything, so as not to have to do it himself.

"Yes, Master." Qian Xiaofeng took the treasure mirror and the jade slip, set up the light and flew towards the teleportation array in the domain. (End of chapter)
