Yin Devouring Ghost Flame is a kind of Yin Fire cultivated by Gu Ya, the half-ancestor of the underworld.

This thing can restrain the talisman, and there are some treasures of the sun.

Dongfang Mo's Yin Devouring and Quenching Bone Technique must have Yin Devouring Ghost Flame before he can cultivate.

Back then, when Dongfang Mo encountered the bone tooth in the underground dark river, this old had no mana at all, and could only spew out low-level Yin Devouring Ghost Flame, and the power was even more unsightly.

He learned from the mouth of the bone tooth that the reason for this was because the Yin Devouring Ghost Flame had no fire spirit.

Back then, in order to escape from the eighteenth layer of hell, Gu Fang left behind the fire spirit of the Yin Devouring Ghost Flame to avoid being detected by the Pure Lotus Dharma King.

Right now, Dongfang Mo's Yin Devouring Bone Quenching Technique, the speed of his own cultivation suddenly accelerated, which made Dongfang Mo suspect that it should be the reason why the fire spirit of the Yin Devouring Ghost Flame was not far from him.

As soon as he thought of this, his mind suddenly came alive.

The bone tooth was sealed here for tens of thousands of years, and eventually escaped.

This gave Dongfang Mo a glimmer of hope, maybe he could find a way to leave from his bones.

But then something suddenly came to his mind.

The first time he encountered Bone Tooth was the second time he went to the underground river to find the spirit vein. And by that time, His Holiness had already left.

The vast supernatural powers of the Pure Lotus Dharma King, Dongfang Mo is seen with his own eyes. So he is now a little suspicious that the appearance of the bone tooth and being touched by him is a coincidence, or it was designed.

If it is designed by someone, the person who designed it is the Pure Lotus King.

The bone tooth has been sealed in the eighteenth layer of hell for tens of thousands of years, perhaps he has already been transformed into a Buddha like the previous bitter treasure, and has since taken refuge in Buddhism.

But when he thought that along the way, Gu Ya had helped him a lot, and his style of acting was completely different from that of Buddhism, Dongfang Mo shook his head again.

He closed his eyes as he pondered, and then began to think carefully.

In the process, he also moved his body in different directions.

After a while, Dongfang Mo opened his eyes and looked in a certain direction.

Through the experiment just now, he judged that moving in the direction in front of him, the Yin Devouring Bone Quenching Technique in his body would be more active.

It can be seen from this that the fire spirit of the Yin Ghost Flame left by the bone teeth in the eighteenth layer of hell should also be in this direction.

So he cast a spell of escape and galloped forward.

As Dongfang Mo fled all the way, he felt that the Yin Devouring Bone Quenching Technique was running faster and faster.

Over the years, this technique has been refining his bones all the time.

The monks of the underworld, although they were all born in the Styx, but strictly speaking, their appearance looks like skeletons.

Therefore, the Underworld monk's quenching power is also to continuously strengthen his skeletal body. The Yin Devouring and Bone Quenching Technique given to him by the bone tooth is the original creation of this old bone, and it can be said that it is the only one in the world.

But at this moment, Dongfang Mo was wondering if the Yin Devouring and Bone Quenching Technique given to him by the bone teeth would be the same as the lotus given to him by the Pure Lotus Dharma King, which seemed to be a good thing, but in fact it was a big pit dug for him in advance.

If at that time, he will cultivate the Yin Devouring Bone Quenching Technique to an extremely advanced level, and the bone teeth can use this magical power to use some unexpected means on him, then I am afraid it will cause him great trouble.

But even so, Dongfang Mo still decided to go to the place where the bone teeth left the Yin Devouring Ghost to take a look. If he was able to find a clue to get out of the eighteen layers of hell, it would definitely be a surprise for him.

In this way, Dongfang Mo escaped all the way for a year.

A year later, he came to a valley of sand that didn't seem to be anything special.

However, after arriving here, Dongfang Mo could clearly feel that his Yin Devouring and Bone Quenching Technique had reached the extreme speed of its own operation.

At this moment, he was suspended in mid-air, looking at the sand valley under his feet, his eyes were full of solemnity.

At the same time, Dongfang Mo also probed his divine sense, and cast the stone eye technique, looking towards the bottom of the sand valley.

His stone eye skills can see through the earth and rocks, and he can easily see what is going on underground. It was only when he penetrated through the underground of more than 10,000 zhang that he found that in the depths of the underground of this place, there was a layer of green prohibition.

After thinking about it, Dongfang Mo touched his chin, because he couldn't see through the prohibition.

"Flutter!"

As his mind moved, a shadow swept out from under his feet, turning into a black shadow the size of a palm, and in a flash it sank into the ground, heading deep underground.

With the speed of this beast, within a moment, it appeared in the place where the Dongfang Ink Stone Eye Technique saw that there was a prohibition.

Dongfang Mo relied on the mental connection with the shadow, as if outside of that layer of prohibition, it was himself, and he could even feel the breath of that layer of prohibition through the shadow.

It's just that this layer of prohibition is extremely strong, and just from the breath, he can judge that it is not something he can open. It can be seen from this that this layer of prohibition should be arranged by the monks of the Half-Ancestor Realm.

Just as he thought of this, he suddenly saw this layer of green prohibition flicker, and then the aura on the surface of this thing began to gradually dim, and finally disappeared completely.

At this time, Dongfang Mo saw through the shadow that in the green forbidden light curtain, there was a huge underground palace with a radius of more than 1,000 zhang.

The floor of the underground palace is paved with a layer of boxy stone slabs, on which incomparably complex lines are depicted.

Dongfang Mo could see that these lines were impressively the power of the law of circulation. This place is indeed arranged by a monk of the Half-Ancestral Realm. This reminded him of Bone Tooth all at once.

What attracted his attention even more was that in the very center of this underground palace, there was a high platform, and on the high platform was a throne, on which sat a white skeleton without a head.

This white skeleton is draped in a red cloak, and its body is leaning forward slightly at the moment, and the wide red cloak behind it is automatically hunting without wind.

In the palm of the slender five-fingered palm of this headless skeleton, there was a small turquoise flame burning.

This cluster of flames was extremely quiet, and there was no aura coming out, and it looked extremely strange to burn in the palm of this headless skeleton at this moment.

Seeing this scene, Dongfang Mo had a slight color in his eyes.

From the breath of that skeleton, he could already be sure that this was the lower half of the bone teeth. Bone Tooth has been by his side for thousands of years, and he is too familiar with the breath of this old scumbag to be familiar with it.

As for the turquoise flame burning in his palm, needless to say, it was also the fire of the Yin Devouring Ghost Flame.

It's just that Dongfang Mo didn't move rashly at this moment, and even a little vigilant in his heart.

The previous layer of prohibition disappeared for no apparent reason, and he suspected that there were others in the place.

"Buzz!"

Just when Dongfang Mo thought of this in his heart, suddenly the space around him fluctuated slightly, and then seemed to be frozen, and he was like a fish frozen in ice.

In the next breath, he was overwhelmed by a strong spatial fluctuation, and all around him became pitch black.

When he reappeared, he was already in the dungeon, suspended in mid-air.

"You're finally here."

At this moment, only a divine consciousness transmission was heard, which sounded in his mind.

Dongfang Mo's heart was vigilant, and at this time, he glanced around, and asked in a deep voice: "Who is Daoyou, why don't you show up." ”

"Boom la la ......"

In response to him, there was a strange noise.

The Yin Devouring Ghost Flame Spirit in the palm of the headless skeleton below suddenly surged at this moment, from a cluster of candle-like volumes, instantly filling this underground palace.

The strange thing is that under the incineration of this flame, neither the ground nor the walls have been damaged by the slightest, and even the temperature has not changed in the slightest.

However, at the moment when he was burned by the Yin Devouring Ghost Flame, Dongfang Mo's face changed greatly.

He looked down at his body, and saw that the clothes on his body were intact, but his flesh and blood, meridians, were melting inch by inch.

What's even more bizarre is that in the process, he didn't feel any pain.

"Damn it!"

Dongfang Mo's face changed.

And in just a few breaths, in addition to the emerald green color of his dantian, his body turned into a skeleton.

Wisps of turquoise flames burned on his bones, shining his bones with a solid green light.

Dongfang Mo's soul and consciousness were intact, and at this moment, he could clearly feel that his bones were slowly getting thicker, and at the same time, the hardness was also rising at a considerable rate. The cultivation speed of his Yin Devouring Bone Quenching Technique was once again increased by more than ten times.

In the sea of fire in front of him, a tall black shadow appeared from the void to the real.

Outwardly, this is an underworld monk. And this person also gave him a feeling of familiarity.

After recalling it carefully, this was the one who had looked at him more when he left.

As soon as Fang appeared, this person looked at him, and Dongfang Mo stared at him.
