Because of the obstacle of these two flame alien races, although Xia Fan's flames had been suppressing their flame advance, they could not burn the bodies of those flame alien races after all.

It was also through the short time that these two flame aliens sacrificed themselves to gain that the remaining flame aliens finally withdrew the spells that were being wrapped in the Silence Demon Fire back into their bodies, and at the same time, they also took away the flame crystal nuclei of the two flame aliens from before.

It's just that just when they knew that there was a huge difference in strength between them and Xia Fan, and were about to find another way to deal with him to the end, they suddenly let out a shout full of shock, anger and incredulity, and then stopped moving as if they had been hit by the immobilization method.

At this moment, wisps of pitch-black flames appeared out of thin air in their bodies that were originally condensed by crimson flames, and they were still spreading outward.

It was as if a drop of ink had fallen into the water, drenching in all directions.

It's just that the ink spreads and only blackens the water, but when the pitch-black flames spread to all parts of the flame alien body, it will kill them.

These pitch-black flames were naturally Xia Fan's Silent Demon Fire.

"Oh, that's amazing, my big brother! This hand is so clever, how did you do it? I don't even understand. The Thirteenth Prince hurriedly walked over at this time and asked curiously.

It's just that as soon as he finished speaking, he couldn't help but cough sharply, followed by a mouthful of blood spurting out, which turned into green smoke again before it landed.

"If you have the skills to satisfy your curiosity, it is better to poison the fire in your body as soon as possible. Xia Fan said, his fingers flicked dozens of times, and then his left hand pinched out a trick, and it slapped on the chest of the thirteen princes with a bang.

If someone else did this, the Thirteen Princes would definitely subconsciously dodge or block. However, in the face of Xia Fan's clapped hand, the thirteen princes calmly endured it.

This magic trick was directly hit into the body of the Thirteen Princes by Xia Fan, and then it suddenly collapsed, turning into wisps of pitch-black flames swimming among the meridians in his body, like a dragon descending from the mountain and swallowing up all the fire poison left in the Thirteen Princes' bodies.

The destructive and aggressive power of the Silent Demon Fire was absolutely powerful, but under Xia Fan's subtle control, it had become much more docile, and at this time, it was swimming in the body of the Thirteen Princes without harming his meridians in the slightest.

"It's so cool!" The Thirteenth Prince only felt that the fiery feeling that enveloped his whole body gradually dissipated, and he couldn't help but praise Xia Fan, and then asked and answered: "Senior brother, you haven't answered my question yet." ”

"Simple. Xia Fan said lightly: "I have long since infiltrated the Silent Demon Fire into those spells, but I have not been able to trigger them, just wait until they take them back and then launch an attack with all their might." ”

"But aren't you afraid that they will find out?" said the Thirteenth Prince.

"That's why I'm going to feint to force them so that they don't have time to scout if those tricks are passive. Xia Fan smiled and said: "Even if they really find out, it doesn't matter, it's a big deal to directly refine and devour those spells, and I won't suffer either." ”

Of course, Xia Fan would not suffer, because at this time, it was the remaining nineteen flame alien races that were suffering.

They didn't expect that they would actually fall into Xia Fan's Dao, but when they realized it, it was already time for the Silent Demon Fire to attack and then wreak havoc in their bodies.

"How can this be?!I checked it, why didn't I find it?!"

"What kind of flame is this, so powerful!?"

"What does that Xia Fan want to do?

"Oh, no, he's trying to refine the law of fire in our bodies, and then wipe out our spiritual intelligence and make us his puppets!"

............

Nineteen Grandmaster Realm Flame Alien Races stood motionless in the air, seemingly calm on the surface, but the battle inside was fierce and dangerous.

Although the Silent Demon Fire was powerful, Xia Fan didn't hide too much in the magic formula in order not to alarm these flame alien races, so it was not easy to win in a short period of time.

It's just that those flame alien races can't suppress or even extinguish the Silent Demon Fire with the flames in their bodies.

Although the two sides were constantly fighting fiercely, unless these nineteen Grandmaster Realm Flame Alien Races could suddenly erupt, the outcome was already doomed, because they were bound to lose.

Of course, Xia Fan didn't want to stalemate, so as not to waste time, so his divine thoughts urged, and another ball of Silent Demon Fire flew out, instantly turning into nineteen parts and flying to the outside of the bodies of those flame aliens, invading from the outside in, and merging inside and outside, in order to capture their bodies as quickly as possible.

At this time, if Xia Fan wanted to kill someone, it was actually quite simple, even if he didn't make a move in person, as long as his mind moved, the fire dragon clone hovering in the air could blow up these nineteen people in an instant.

However, Xia Fan didn't do that, because just now, he felt that he could make better use of these flame alien races.

The method that Xia Fan thought of was to use the Silent Demon Fire to refine these flame alien races, so as to completely control them in his hands and drive them at will.

The reason why he thought of doing this was also because Xia Fan felt that the flame alien race was condensed by flames. And these flames are infused with fragments of the law of flames, so as long as the laws of these flame fragments can be broken and reshaped and leave their own imprints of divine thoughts, then they can be turned into their own.

This process is actually similar to refining a cultivator after obtaining a new magic weapon or flying sword, and even the previous Silent Demon Fire was also refined by Xia Fan in this way.

Of course, the solution is simple and clear, but it is not so simple to succeed.

First of all, although the bodies of these Grandmaster Realm Flame Alien Races were all condensed from flames containing law fragments, and the stronger they were, the more law fragments they had in their bodies, but it was not easy to break them first and then reshape them like something that Xia Fan had put into his pocket to swallow the sky, and then add his own divine thought brand.

Because of this process, it is actually much more difficult than reshaping Antura Mountain, Nine Demon Mountain, etc. in the Heaven Swallowing Pocket.

After all, in the Sky Swallowing Pocket, he also has the Shattering Divine Light to help him smash everything, and all the rules in the Sky Swallowing Pocket are based on his thoughts, so he can naturally do whatever he wants.

But outside, whether it was shattering the body of the flame alien race or reshaping it, he had to do it himself with the help of the Silent Demon Fire. It's really difficult.

Secondly, the flame alien race is also different from the Antura Mountain and the Nine Demon Mountain, which have no consciousness and soul, the latter will obediently let Xia Fan smash and reshape, but the former has his own sanity, so naturally he will not obediently obey.

Especially the more powerful the flame alien race, the stronger the power to resist, and the less likely it is that what Xia Fan wants to do will succeed.

Third, the flame alien races that Xia Fan wanted to refine this time were not just one, but nineteen.

This meant that he had to manipulate the Silent Demon Fire to suppress the resistance of the flame alien race's divine souls at the same time, and at the same time shatter the fragments of the flame law that condensed into their bodies, and then reshape them according to his own rules and leave the imprint of divine thoughts at the same time, which can be imagined.

Because each flame alien race is different, which means that the refining of them is different, this is naturally quite a tedious thing, just thinking about it already makes people feel big, not to mention that they need to do it themselves.

Since Xia Fan had this idea, of course he didn't expect it to be particularly easy. Of course, the effort is great, but if he can succeed, the benefits he can get will only be greater.

As the Flame of Silence spread within these flame aliens, causing their movements to be restricted, the nineteen flame aliens suddenly became terrified.

Of course, they were not willing to be erased by Xia Fan, and they didn't want to become puppets under his control, and they would be driven by it from now on, but in the face of the Silent Demon Fire with equally powerful invasion and destructive power, they had no way to effectively contain it.

So much so that although his heart was extremely anxious, he could only watch as the Silent Demon Fire raged in his body, and his body became no longer under his control wherever he went. This experience really makes them feel helpless and frightened.

"I'm not going to let Xia Fan get his way... Bang ......" shouted angrily, and one of the fierce-tempered flame aliens directly detonated the flame crystal nucleus.

Since the flame crystal nucleus is the core of the flame alien race, it is equivalent to the demon pill of the demon race, and the spiritual pool of the cultivator exploded at this time, not only did the soul of the flame alien race completely dissipate, but also the body collapsed and disintegrated.

Although in the midst of the violent explosion, the Silent Demon Fire that had penetrated into its body took the opportunity to devour a large number of flame law fragments that were about to be dispersed due to the loss of restraint due to the explosion of its flame crystal nucleus, which could be regarded as a small gain, but it would definitely not refine it to gain more.

"Bang ......" Seeing his companion do this, of course, there will be flame aliens who will do the same.

Although Xia Fan wanted to stop this, the Silent Demon Fire that was accelerating under his control was still some distance away from the flame crystal nucleus at the core of those flame alien races. This made it impossible for him to forcibly suppress them, so he could only watch them explode with helplessness and regret.

After five flame aliens blew themselves up in a row, Xia Fan finally forcibly restrained this crazy behavior.

Because not only did the Silent Demon Fire in the body of the Flame Alien Race invade the flame crystal nucleus of the remaining Flame Alien Race, but the Silent Demon Fire outside also invaded it, and the inside and outside should be combined, speeding up the speed of refining.

"Ahh

At this time, although they could not move, they could speak, and they roared with great anger and grievance.

It's just that Xia Fan can't understand their words, and even if he can understand them, no matter whether their words are begging for mercy or cursing, he won't take them to heart.

After all, in Xia Fan's opinion, these flame alien races were not human beings at all, so there was no need to have even the slightest mercy towards them. Especially since they have just brutally killed hundreds of thousands of their own people, then it is appropriate to kill them and torture them, and there is nothing difficult to accept.
