However, it was up to Mo Xiu to determine what kind of laws and wills to absorb, and it couldn't be absorbed indiscriminately.
Otherwise, even if it could become a Shadow Demon Guard of the demon king-level, the strength might not be comparable to those immortal kings or demon kings.
Mo Xiu took a deep breath, temporarily set aside the eight Shadow Demon Guards who had been soaked in the evil spirits, and patiently selected the right laws and the wills of the ancient immortals and demons.
"The Law of Ice, Extreme Frost Immortal King... this seems to be a bit like the power of Snow Spirit Immortal Queen, and it's barely passable."
"The Law of Darkness, Abyss Demon King? This should be the legendary Abyss Demon King from that era."
"The Law of Heavenly Rainbow? It seems weak."
"The Law of Flame, Sky Flame Demon King? It happens to be a match with the Extremely Frost Immortal King's Law of Ice."
"The Law of Death... there is even this kind of law?"
...
Mo Xiu carefully selected for a while, and quickly picked out several laws, together with eight powerful wills of the ancient immortals and demons, which were absorbed by the eight Shadow Demon Guards.
The demon king-level Shadow Demon Guards were gradually taking shape.
…
About a month passed, when the eight Shadow Demon Guards returned to Mo Xiu and lined up, Mo Xiu couldn't help but breathe a sigh of relief.
Before, he didn't know when the immortal kings of Immortal Race would come to his door, and his mind was always tense.
Now that there were these eight demon king-level Shadow Demon Guards, even if there were immortal kings coming to the door, he was not without the power of a fight.
As long as all the immortal kings in the Realm of Heaven did not take action together, he should have no problem getting out of it.
He looked at the eight Shadow Demon Guards again, feeling satisfied, then he raised his hand and ordered the eight Shadow Demon Guards to go back into his shadow.
There was no news from Mo Lanyuan, Saintess Qing Ru, Jian Zhishang and others, nor any signs of danger, probably because their respective Shadow Demon Guards had not been refined.
It was normal to think about it, the method of refining the Shadow Demon Guards was not so easy to understand.
Even if Mo Xiu had pointed out all the points and engraved them in the Sea of Consciousness of everyone, it did not represent that they could understand everything.
What's more, it was one thing to understand thoroughly, and it was another thing to actually refine it for real.
Many people had a high comprehension ability and could easily understand the refining method. But when they really started, they might not be successful in refining. Especially in the initial stage.
Like Mo Xiu, with a high understanding and strong comprehension ability, such a person like himself was rare.
Otherwise, there would be no Mo Xiu, and there would be no Everlasting Demon King.
Since those people hadn't refined their respective Shadow Demon Guards, Mo Xiu didn't intend to bother.
After thinking for a while, he explored his Divine Consciousness into the Five Elements World, communicated with Yuan Rou, and asked Yuan Rou to temporarily move out the contents inside the Heavenly Path Scripture Pavilion until the Heavenly Path Scripture Pavilion became empty.
Mo Xiu had already sealed the Heavenly Path Scripture Pavilion before.
But when the Heavenly Path Scripture Pavilion had just left the Five Elements World and came to the core area of the Ancient Immortals and Demons Battlefield where Mo Xiu was, the seal on it was automatically washed away strangely.
"Buzz..."
The Heavenly Path Scripture Pavilion kept vibrating and soon dragged Mo Xiu towards a certain direction in the depths.
Fortunately, Mo Xiu was now completely unaffected by the evil spirits in the Ancient Immortals and Demons Battlefield, and the scattered laws around him and the wills of the wandering ancient immortals and demons couldn't affect him, otherwise, he really couldn't stand it.
He followed the Heavenly Path Scripture Pavilion for a while, and soon Mo Xiu was surprised to find that he had come to a gray space, a place he had never seen before.
"There is such a place in the Ancient Immortals and Demons Battlefield?" Mo Xiu was really surprised.
In his previous life, he entered the Ancient Immortals and Demons Battlefield. It could be said that he had explored all corners of the Ancient Immortals and Demons Battlefield.
But he did not find similar places at all, but now, it seemed that he had underestimated the Ancient Immortals and Demons Battlefield.
Perhaps he failed to find the treasure the last time he entered the Ancient Immortals and Demons Battlefield, not because there were no treasures in the Ancient Immortals and Demons Battlefield, but he really failed to find the treasures.
He condensed his mind and looked around as he continued to fly forward following the Heavenly Path Scripture Pavilion.
Although the surrounding area was gray, it didn't look dangerous. It only had a sense of mystery as if there were endless secrets hidden in this place.
"Ancient immortals and demons… and true immortals and demons... Maybe there are many similar places in Realm of Heaven, but no immortals and demons have ever found those places?"
"The ancient immortals and demons are relatively easy to deal with. The true immortals and demons are the biggest hidden dangers, but I don't know where they are hiding."
"Are they hiding? Are they regaining their vitality and waiting for a comeback? Or is there a place in the Realm of Heaven that even they have to fear so they don't dare to show up easily?"
Mo Xiu's thoughts diverged and his mood became a little heavier inexplicably.
In his previous life, he was recognized as the strongest demon king in the Realm of Heaven, and he could even be said to be the first person in the Realm of Heaven.
But now, it seemed that it would be changed.
If those true immortals and demons hiding in the dark emerged, he wouldn't be the strongest in the Realm of Heaven anymore.
In this life, even if he had cultivated to the height of his previous life, he would definitely not become the strongest in the Realm of Heaven.
Among other things, Ruthless Demon Sovereign alone was said to be more powerful than the Everlasting Demon King at his peak.
If he wanted to take revenge and become the strongest in the Realm of Heaven again, then he must be stronger than his previous self, to reach a height that he would not even dare to think at the peak of his previous life.
As he was thinking so, suddenly he heard a voice, "Master, I feel the breath of my ancestor."
"Huh?" Mo Xiu frowned slightly.
It was not someone in the Five Elements World or someone in the Ancient Immortals and Demons Battlefield that just talked, but Nightmare Demon Hound that Mo Xiu conquered at the side of the Seraphic Sword Sect.
Although Nightmare Demon Hound came a bit later than the Shadow Demon Guards, it was not much different.
But like the Shadow Demon Guards, he might not use the Nightmare Demon Hound for a long time, because the Nightmare Demon Hound's strength was still far from enough.
With the passage of time, Nightmare Demon Hound would definitely be able to grow stronger little by little, but the speed of Mo Xiu's cultivation was too fast, and the growth rate of Nightmare Demon Hound couldn't keep up with the speed of Mo Xiu's breakthrough.
Because of this, in the beginning, Mo Xiu used the Nightmare Demon Hound to help fight several times, but when it got behind, the enemies he encountered became stronger and stronger, and gradually he didn't dare to ask the Nightmare Demon Hound to come out to help.
If it really came out, the Nightmare Demon Hound would not be able to eat any good fruits even if it would not be killed by a spike.
Considering the potential of the Nightmare Demon Hound, Mo Xiu did not completely give up the Nightmare Demon Hound, but kept the Nightmare Demon Hound in his shadow all the time.
But he never expected that Nightmare Demon Hound would talk to him at this time, and he didn't even expect that this mysterious space would have the breath of the ancestor of the Nightmare Demon Hound.
He quickly asked, "The breath of your ancestor? Is he alive?"
Although he had always thought that there were no people living in the Ancient Immortals and Demons Battlefield other than them, and he didn't think there was any existence that could threaten him in the Ancient Immortals and Demons Battlefield, but now he was in a place that he had never explored before.
To say that there were unknown dangers in this mysterious space, hiding terrible existences that he couldn't handle, he was willing to believe.
And if the ancestor of the Nightmare Demon Hound was in this space and was still alive, it was not impossible. After all, the unknown meant that everything was possible.
