In terms of refining, although Lu Qingshan is not as good as some ancient figures in the Ancient Immortal and Demon Era, he is also extremely accomplished, and refining a treasure that contains the spirit of the wandering soul is naturally very simple.

It's just that it just takes some time.

If Lu Qingshan didn't want to hunt down those demons, he would naturally have a lot of time to refine, but now, there is indeed some tension in terms of time.

Despite this, Lu Qingshan still began to refine.

The black python itself is a demon that breaks the nine, and its whole body is full of treasures, Lu Qingshan removed its flesh and blood, and threw it all to the demon dog, and its white bones were extracted by Lu Qingshan, washed cleanly, and calcined with dragon flames.

Finally.

Two days later, on the white bones of the black python, there was no longer a demonic breath, but a bright and righteous aura circulated.

The demon dog who swallowed the flesh and blood of the black python looked at the white bones of the black python and couldn't help but say: "Master, this breath is too open, those wandering spirits are going to be burned clean when they get into it!"

"No, it won't!"

Lu Qingshan shook his head and explained with a smile: "The wandering soul belongs to yin, and this white bone, after my refining, is already yang, and the combination of yin and yang can make those wandering souls last forever." ”

"Moreover, with the white bones to nourish, those wandering spirits will only be stronger than ever!"

The demon dog was puzzled and couldn't figure it out.

Lu Qingshan raised his hand, and a ghost immediately floated over in fear, Lu Qingshan smiled and comforted the ghost: "You'll be fine, you try to get close to the white bones of this black python!"

The spirit was pasted, and he always felt that he was going to be scattered, but, unexpectedly, it was warm and warm, and there was no discomfort at all, and he could feel that although he was a ghost, but because of the power contained in the black python's white bones, he was becoming stronger.

At the very least, the figure manifested by the geist became more staring, and he had to doubt that one day he would be able to condense his true body.

Of course, what he didn't know was that at that time, if the body was really condensed, it would be the so-called "ghost and immortal body".

"Okay, you leave first, and when I'm done, you can come in again!" Lu Qingshan waved his hand, and the spirit immediately flew out and continued to float in midair.

But Lu Qingshan continued to refine.

The white bones of this black python, just like that, that will not work, so Lu Qingshan dismantled these white bones according to his needs, and according to the special refining technique, after three days, he refined a bone tower like mutton fat jade.

The quality of this bone tower alone has reached an extremely high level, and with the bone tower, it can fight with the Nine Stronghouses for 3,000 rounds.

"What is this tower...... Let's call it the Nine-Story Demon Tower!"

Lu Qingshan gave a name.

The nine-story demon tower has a total of nine floors, and each floor has a separate layer of space, just like a blessed land.

Lu Qingshan beckoned, those wandering spirits were all overjoyed, and before entering the nine-story demon tower, they bowed to Lu Qingshan again, their eyes showing gratitude.

"You can only stay here now, and when you have the chance, I will send you to reincarnation! Of course, it's not the reincarnation of the first universe, the reincarnation here has collapsed!"

Lu Qingshan spoke slowly.

After all the wandering spirits entered the Nine-Story Demon Tower, Lu Qingshan put away the Nine-Story Demon Tower, directly put it into his body, and continued to practice with his own strength.

With the refinement, the power of this nine-story demon tower will rise, and these spirits can increase their strength in the nine-story demon tower.

"Ergou! We have been delayed for some time, and we have to continue to track down those demons! In the past two days, I have sensed it, and there are two demons, and I don't know if they have found the mark I left, anyway, the mark is gone, and I can only find the last location of the mark!"

"When the time comes, you'll have to rely on your nose!"

Lu Qingshan's figure jumped up and sat directly on the demon dog.

Because of devouring the flesh and blood of the black python, the strength of the demon dog has increased a lot, and at this moment, carrying Lu Qingshan, the speed of the demon dog can't help but become faster.

"Master, don't worry! There is some breath that the master may not be able to detect, but the little demon can smell it!"

The demon dog immediately reassured and said: "In this world, except for the master, the little demon has no way at all, but under the master, except for a few demons, the vast majority of them can't escape the little demon's nose!"

"It's a good thing that you have that faith!"

Lu Qingshan.

Three days later.

The demon dog carried Lu Qingshan and appeared in a barren mountain, Lu Qingshan said: "The mark disappeared here, Ergou, you sniff carefully and see if you can find it." ”

When the demon dog heard this, he immediately sniffed hard, and after a while, the demon dog said: "Master, I have found the direction of leaving, and the little demon will carry the master over!"

So, after walking for two more days, the demon dog barked wildly outside a hole in the ground.

Lu Qingshan walked down and asked, "Inside?"

"Yes!"

The demon dog replied.

"You wait for me here, I'll go down and have a look!"

After speaking.

Lu Qingshan's figure flickered, and he burrowed into the hole, and then, Lu Qingshan's body turned into blue lightning and went deep quickly.

Really.

In the cave, many arrangements were made along the way, some traps, some barriers, and some formations.

It stands to reason that these arrangements are enough to resist many strong people, however, in front of Lu Qingshan, these arrangements are useless and have no effect at all.

Lu Qingshan's speed is too fast, he can shuttle through completely, and these arrangements can't even be sensed.

And in the cave of the ground, a figure was shrouded in black mist, and the light was dim, so that people couldn't see it clearly at all, even if the spiritual power of some strong people spread, they couldn't feel it here.

Now.

This person was hiding in the deepest part of the cave, making many arrangements in front of him, and he himself was silently cultivating, striving to keep himself at the peak at all times.

"Hmph! That person doesn't know where he came from, but he can even kill the Bone Forest Demon Venerable!

"Fortunately, I found the mark left on me by the man in advance and destroyed it, so that it would be impossible for the man to find me. ”

"After all, so many people may not be the first to look for me, if they really look for me, it will also take a lot of time, and when the time comes, the nine masters over there, as long as someone can free their hands, that person will also die!"

"It's a pity, the demons are all selfish, otherwise, the Bone Forest Demon Venerable wouldn't die, and I wouldn't have fled......"

The man shook his head, but suddenly, he seemed to feel something, and his eyes couldn't help but become solemn, and he looked in front of him.

However.

In the hole, it is crooked, and you can't see far.

But, at this moment, he faintly saw a touch of blue, and it disappeared in a flash!
