Demon Emperor sector, demon mansion of the eastern region.

Ye Changge cultivated for a while and refined the materials he obtained into pills to repair his body once again.

When everything was ready, he took a look at Ah Hu's situation, the Wang family's situation, and that of the others before arriving at the Earth Fire Refining Workshop.

At that time, when he came here, he was busy lecturing those refiners. He had forgotten to sign-in.

Although from that exchange, he also learned a lot of things. Those were all refining techniques that the refiners of the Heavenly Mortal World did not know.

When he first came to this earth fire refining ground, he discovered the differences here.

This time, he came specially to sign-in.

When Ye Changge came here, he received a warm welcome.

Thousands of demon cultivators who were refining artifacts here bowed respectfully.

"System, sign-in."

Ye Changge silently chanted in his heart.

"Ding! Congratulations, host, sign-in successful."

"Congratulations, host, for obtaining the [ Demonic Fire for Nerve Formation ] ."

Ye Changge was startled.

Could it be another cultivation technique?

Ever since he came to this Demon Emperor World, every time he came to a slightly special new place, the reward he received when he signed-in seemed to be a cultivation technique.

The first time he checked in at the Death Aura Forest, he had obtained several cultivation techniques.

Could this be another cultivation technique?

Ye Changge's gaze swept across the refining field, but in reality, his mind was immersed in the system rewards.

"Demonic Fire for Nerve Formation. It can collect all the strange flames in the world, enlighten them, or turn them into demons."

"All the flames can be fused to form a strange fire demon."

"The strength and ability of a fire demon depends on the nature of the demonic fire."

This was actually a secret technique to nurture fire demons.

Ye Changge was happy.

With this secret technique, he could obtain even more powerful flames. Not only could he use them to fight enemies, but he could also strengthen his refining techniques.

Ye Changge's mind expanded, and he summoned his own spiritual fire.

The dancing flames had different fluctuations, and there were several rings of different colors. It seemed to have its own spirituality.

This spiritual fire did not have a name. It was a flame that he had been looking for since he had just started refining in the Heavenly Mortal World.

After being nurtured and improved by him, the power of this flame was already very strong.

Without the slightest hesitation, Ye Changge activated the Demonic Fire for Nerve Formation and began to light up the spiritual fire.

Bang!

The flame kept fluctuating, sometimes bigger and sometimes smaller.

His every move was being watched by the refiners of the refining hall.

The flame was very powerful to begin with, and it seemed to be full of spiritual energy.

When Ye Changge activated the Demonic Fire for Nerve Formation, the flame seemed to come to life and began to jump differently.

The refiners here were all demonic cultivators, and they all knew what had happened.

Spirit awakening!

"This, this spirit fire is about to become sentient?"

"Master, what's going on with this spirit fire? Did you feel any intelligence just now? Is it suddenly about to awaken its intelligence?"

"Hiss, why do I feel that this new demonic cultivator's strength is very strong?"

"Nonsense, this is master's spirit fire. Of course, its power is very strong."

The fluctuation of the spirit fire was getting faster and more intense.

At the same time, the demonic aura and spiritual energy began to pour into the spiritual fire.

The countless earth flames in the Earth Fire Refining Ground were burning fiercely, and those flames crazily poured into the spiritual fire.

"This is really going to transform!"

"This is terrifying. What's going on? Such a disturbance, is some kind of great demon about to be born?"

"The temperature is very high, at least many times higher than our spiritual fire."

The surrounding refiners whispered to each other.

Ye Changge did not care about them.

Most of his mind was focused on the spiritual fire, sensing its changes.

The other part of his mind was focused on the surrounding environment.

Someone invaded it!

The corner of Ye Changge's mouth curled up.

"It seems that someone is coming, sneakily. I don't know what their purpose is."

However, according to the scan of his spiritual senses, the strength of those intruders was the same as the strength of the group of people he had encountered earlier.

For such beings, it was only a matter of one sword strike. Ye Changge could not be bothered to care too much about it.

And the spiritual fire was beating faster and faster.

A gust of life began to spread out.

The surrounding demonic cultivators stopped discussing. They looked at the spiritual fire seriously and felt the increasingly dense demonic qi it was emitting.

The spiritual fire's throbbing gradually became regular, as if it was pulsating at a certain frequency.

Finally, the fire completely transformed, and a new demonic creature was born.

Countless refiners were filled with amazement.

Although they didn't know how it was done, everyone could be sure that it was definitely done by Ye Changge.

"Master's methods are so terrifying."

"As expected of a master, he can actually transform his demonic fire!"

"We are still using ordinary demonic fire to refine artifacts, but master has already started using transformation demons to refine artifacts."

"Haha, as expected of a master. I hope that my demonic fire will one day transform as well."

Amidst this discussion, the body of the spiritual fire slowly changed.

The flames contracted, revealing the shadow of a woman.

A voluptuous figure dressed in flaming armor with a gorgeous face appeared.

She was in Ye Changge's palm and she bowed to Ye Changge seriously.

"The fire spirit greets master. Thank you for your call!"

"Yes, you are my artifact-refining fire spirit. From now on, you shall be called Yaoyao."

Ye Changge gave the fire spirit a name.

"Thank you for the name, master!"

Yaoyao's flames fluctuated very quickly. It could be seen that she was very happy.

Everyone in the refining ground watched in shock.

At this moment, a colorless and tasteless smoke appeared in the refining ground.

Ye Changge frowned.

The smoke spread very quickly. In a short while, it covered all the refiners here.

Plop!

One after another, the blacksmiths fell to the ground.

Almost all the blacksmiths fell to the ground.

Ye Changge felt a powerful spiritual energy making its way into his body.

The smoke was not only harmless to his body, but also had great benefits.

Ye Changge found that they were repairing his body.

Feeling happy, Ye Changge also slowly sat down on the ground, as if he was affected by the smoke.

At the same time, his body rapidly absorbed the colorless smoke, and his cultivation technique quickly circulated to repair his body.

Clap Clap Clap Clap.

Waves of clapping sounds rang out.

At the same time, five demonic cultivators walked in.

They were two men and three women, all dressed differently. They were all demonic cultivators.

"As expected of a masterful weaponsmith. The skill that the master displayed just now really made me gasp in amazement."

"Moreover, this heavenly dew is a great tonic. When ordinary demon cultivators absorb it into their bodies, their bodies will automatically absorb it and they will basically faint. However, the master is just sitting on the ground."

"Don't worry, master. Although this heavenly dew will make people unable to move and faint on the ground, it won't do any harm to the body."

"Master, we are from the southern region's demon mansion. We hope that you can come to our place. The demon lord will definitely fulfil anything you request."
