Zeng Xiaoyu suddenly had a thought, in the secret technique of the Spark Burning Plains, there was a secret technique that could make the spiritual fire of heaven and earth continue to advance.

It is to use two heaven and earth spiritual fires of the same level, and after devouring and fusing each other, a new kind of flame is formed.

Now Zeng Xiaoyu already has two heaven and earth spiritual fires of the same level, Nanming Lihuo and Red Lotus Karma Fire.

Nanming Lihuo and Red Lotus Karmic Fire, one is dedicated to matter, and the other is dedicated to the soul.

If the two can be fused so that the new spiritual fire has two qualities at the same time, then the power and effect of the spiritual fire will definitely be greater!

Just do it if you want to, Zeng Xiaoyu began to take back Nanming Lihuo in front of him, and released the red lotus karmic fire in his body next to Nanming Lihuo.

Zeng Xiaoyu immediately urged the secret method and slowly let the two flames continue to fuse.

Zeng Xiaoyu repeatedly and continuously injected many magic seals into the two spiritual fires in front of him.

Under the action of the Dharma Seal, the two heaven and earth spiritual fires began to approach each other and merge with each other.

This process is quite amazing, the flames of one blue and one red slowly turn into a golden flame through continuous fusion.

This flame is better than the original two flames in terms of heat, breath and breath.

And it has the advantages of both flames.

Zeng Xiaoyu didn't know what the name of this new flame was, but he sensed the power of the flame a little and found that the power of the flame at this time was very extraordinary.

Zeng Xiaoyu's face was happy, and he immediately snorted and pointed with his hand.

The golden flame the size of a human head immediately pounced on those Heavenly Demons.

At this time, those heavenly demons were continuously impacting the Kunpeng Thunder Shield in front of Zeng Xiaoyu.

Under the impact of many heavenly demons, the Kunpeng Thunder Shield began to become shaky and a little unstable.

At this time, this strange fire came in an instant.

As soon as the strange fire came, it rushed towards those heavenly demons.

As soon as those Heavenly Demons were touched by this spiritual fire, they immediately let out a terrified scream, and quickly flew towards the outer line of the sky, as if they had encountered something that frightened them.

Once these Heavenly Demons were touched by the flames, they immediately began to burn until they were completely destroyed.

And the flame is contagious.

When one Heavenly Demon is touched, it will be transmitted to the second one, and the second one will be transmitted to the other Heavenly Demons.

Such a strange flame is very lethal to the Heavenly Demons, and it has also become a nightmare existence for the Heavenly Demons.

Therefore, this group of heavenly demons who were originally not afraid of death dispersed like birds and beasts in an instant and disappeared without a trace.

Zeng Xiaoyu looked at the Heavenly Demons who scattered in a hurry with some astonishment.

I thought to myself: It turns out that these Heavenly Demons are not really invincible, but there is nothing to restrain them.

Once they find a way to restrain them, they won't just rush at them without fear of death.

Seeing that those heavenly demons had dispersed, Zeng Xiaoyu nodded with satisfaction, and with a movement of his mind, he re-incorporated this flame into his body.

Zeng Xiaoyu went out of the sky and headed towards the destination again.

Perhaps because Zeng Xiaoyu refined Nanming Lihuo, the fire in this sea of fire had no effect on Zeng Xiaoyu.

Instead, a steady stream of fire attribute energy poured into Zeng Xiaoyu's body and was absorbed by Zeng Xiaoyu.

Growing the newly generated spiritual fire in the body.

Whenever those wandering Heavenly Demons wanted to take the opportunity to attack Zeng Xiaoyu, Zeng Xiaoyu only needed to move his mind, and a golden flame would ignite on his body.

As soon as those heavenly demons saw the flames on Zeng Xiaoyu's body, they were immediately frightened and fled, not daring to get close to Zeng Xiaoyu for half a step.

Without the hindrance of the Heavenly Demon, Zeng Xiaoyu went all the way unimpeded and continued to rush towards the destination.

Along the way, Zeng Xiaoyu was also thinking to himself.

According to Zeng Xiaoyu's guess, the predecessor who fell in the first line of heaven must have been one of the three human powerhouses who entered the underworld back then.

According to the Northern Regions Hades King, at that time, the three human powerhouses united several Hades kings to fight the extremely powerful extraterritorial heavenly demon together.

In the end, not only did several Hades kings fall here, but also two peerless powerhouses from the human world fell in this place.

This sea of fire should be the strong man who cultivated the Yan Emperor Fire Sutra, and it was released by that strong man.

It is estimated that it is under the guise of the idea of dying with the heavenly demons.

This speculation made Zeng Xiaoyu solemnly moved.

In my heart, I admired that senior.

Who is a monk who spares his life and sets out as a last resort, and who is willing to use all his skills to fight with others?

But this senior is obviously already thinking of breaking the cauldron and planning to die with the extraterritorial heavenly demons!

"That should be the destination of this trip. ”

Zeng Xiaoyu looked up at a peak in front of him, and his face showed joy.

After all the hard work, we finally arrived at our destination.

Zeng Xiaoyu did not stop, and flew directly into the air, and soon flew up to the mountain.

As soon as Zeng Xiaoyu flew up the mountain, his eyes immediately shrank.

At this time, on the top of the mountain, there is a monk sitting cross-legged!

The monk sat there, motionless, apparently dead for a long time.

In front of him, there was a transparent vajra cover.

Inside the vajra cover, a black seed is sealed.

The black seeds exude black qi at all times, and various heavenly demon shapes are conjured on them all the time.

Opposite the monk, a black skeleton sits cross-legged.

In front of the dry bones, there was a black wheel.

"Reincarnation wheel!

The Northern Hades King is right! Her master has really fallen here!"

Zeng Xiaoyu looked at the black dry bone in front of him, and he was already sure in his heart that the skeleton in front of him should be the master of the Northern Regions Hades King!

The people of the underworld are mainly cultivating the power of the soul, and the physical body is weaker.

Therefore, it is very powerful to be able to leave a skeleton after death.

As for the remains of the monk in front of him, they still retain their appearance before his death.

This is an old monk with kind eyebrows and kind eyes, and his eyebrows and beard are white.

Even though he has been dead for a long time, he still maintains the appearance of holding the Dharma seal before his death.

Looking at it like this, this high monk and the master of the Northern Regions Hades King were trying to suppress that heavenly demon, and they all fell here in the end.

And that heavenly demon should be the thing sealed inside the vajra cover in front of the old monk at this time!

Zeng Xiaoyu was in awe.

After all, when facing the devil, there are not many people who can sacrifice themselves and use their lives to suppress the devil.

This is a kind of spirit and spirit that I don't go to hell, who goes to hell!

This spirit of courage and sacrifice is easier said than done.

After all, who doesn't care for his life?

If it weren't for the sake of justice, if it wasn't for the point of necessity, who would have been able to sacrifice their lives so remarkably?

Zeng Xiaoyu let out a long sigh, stretched out his hand, and took a picture of the turning wheel on the ground.

But at this moment, the mutation is abrupt!

I saw that the black seed that was originally suppressed in the vajra cover suddenly turned into a black light, shot out from the vajra cover, and shot towards Zeng Xiaoyu's eyebrows!!

"Takeaway!"

Zeng Xiaoyu was shocked in his heart, and without thinking about it, he immediately stimulated the golden flame that he had just practiced and spread it all over his body.
