According to Gao Jingfei's understanding, this earth fire crystal can also be regarded as one of the treasures of heaven and earth, among which the Taoist master and ghost immortal Liu An, who is good at alchemy, has mentioned this kind of treasure.

In the Xianmen Taoist sect, this thing is regarded as a fire attribute material used as a fire source for alchemy tools, as long as it is given abundant aura, it can release pure earth fire for monks for a long time, and its consumption period is based on 10,000 years.

Often, from the establishment of a cultivation sect to its destruction, this thing has not completely lost its usefulness!

Earthfire crystals are generally bred in the earth's lungs and underground lava, and are usually sprayed to the ground only by volcanic eruptions, but they can also be found near active volcanoes, which is a relatively easy source of spiritual fire.

Although the earth fire contained in this earth fire crystallization is not as high-end as the true fire divine fire such as Samadhi True Fire, Tushi True Fire, and Nanming Lihuo, it is easy to obtain, the fire is stable, and it is also one of the more suitable fires for alchemy.

Of course, the earth fire crystallization is not directly used, but also needs a spiritual vein at least the warm supply of the earth vein spirit cave, so that the energy can continue to produce earth fire, through the purification of the earth vein aura, it will also eliminate the impurities and evil qi contained in the earth fire, which is more born in the earth lungs, and the earth lung poison fire is a terrible existence where the earth evil qi gathers, once it erupts, it is no less than the terrible disaster of the earthquake of the year.

Gao Jingfei does not lack spiritual veins, and even has a whole small dragon vein, as well as a supply of spiritual energy from the Pure Yang Kingdom and the Cave Heaven Blessed Land, using this earth fire crystal as a fire source, it can be used for more than tens of thousands of years, and this is still the case that the Fairy Forest and the Jade Dragon Vein are not replenished.

And as long as the aura is recycled and consumed and regenerated, then it can definitely be called an eternal energy.

After receiving this key Earth Fire Crystal, the temperature of the entire lava pond seemed to have cooled, and the originally red lava became a little darker.

The good things had been taken away by him, and Gao Jingfei had no reason to stay in the cave, so he immediately opened the spatial portal, and took the shocked Henry Toru and the two stepped out of the portal and came to the outside of the cave entrance.

"This ......"

Henry had no words to describe his current mood, and the thought of hugging his thighs suddenly rose up stronger than his thoughts when he was a student, determined to make a lot of money, filial piety to his mother, and pursue a goddess classmate.

As for Tolu, the humble werewolf, his thoughts at this time can be described in one word, that is, "surprise"! There was no other thought.

And Gao Jingfei ignored the thoughts of these two guys, because as soon as he teleported, the lava monster that had been lured out of the lair by the two detectives to the ground was already running in his direction.

The heavy footsteps brought by the huge body shook the ground around him.

And the lava monster's stone face, which was originally expressionless, showed an angry look at this time, don't ask how do you know, the eyes and nostrils are angry and spewing fire, isn't this anger or anger?

Obviously, the lair was taken away, and the treasures he guarded were stolen, which made this irrational lava monster even more crazy.

Gao Jingfei, who had just finished stealing his home, looked at the lava monster that looked like he was running, and couldn't help but touch his nose a little sneeringly, but he quickly put this idea of being a loser behind him, after all, the other side was not a kind creature, but a rampaging brainless monster, which was a big threat to humans in itself, and he didn't mind cleaning it up if he bumped into it.

So I saw Gao Jingfei stretch out his hand towards the lava monster that was less than twenty meters away from him, and then a cold air erupted in the other party's body out of thin air.

This is a move developed by Gao Jingfei after mastering the Kanbu Forbidden Law in the Eight Forbidden Methods of Taiyin, because it is the principle of using the power of water to cause extremely cold and freezing gas, so he named this move "Frost Nova".

The lava troll, which had been covered in crimson flames in the cracks of the stones, was hit by this blow of Frost Nova, and the low temperature of minus tens of degrees Celsius collided with the high temperature of hundreds of thousands of degrees Celsius on the surface of its body, producing drastic changes.

I saw a white mist surging out like a big steamer in winter, and the stones on the surface of the lava monster's original body also made a thunderclap cracking sound, and the crimson fire was extinguished and turned gray.

Coupled with the kinetic energy of the lava troll's running, the entire troll's body also collapsed forward, and then piled up on the ground like a small mountain.

This made the two detectives Nathan and Hans, who were chasing behind, stunned, the two terrible monsters that they had no way to fight or even harm, and they were so easy to get rid of?

For a moment, Hans, the demon hunter's assistant, couldn't help but glance back and forth between his partner and the transcendent who suddenly appeared, and his suspicious expression was self-evident.

Could it be that this is the real Transcendent Boss, and Nathan is just a rookie?

However, Gao Jingfei knew that this runaway mutated lava monster had only been hit hard, but it was not dead yet, because the powerful aura in the other party's body had not been extinguished.

Come to think of it, this is also a B-level transcendent creature that is congenitally upward, and even in terms of single combat power, it can already be compared with a higher-level A-level transcendent, but it has just mutated not long ago, coupled with the restrictions of the laws of the world, so it has not been able to break through the limits of the B-level.

According to Gao Jingfei's observation, this lava monster was guarding the earth fire crystal, and at least the upper limit of its strength was at the level of the Yin God.

Because the Earth Fire Crystal itself is a treasure that is not inferior to the Golden Legendary Magic Weapon.

Therefore, when the lava monster seemed to turn into a pile of rubble and hang up, Gao Jingfei was not careless, but summoned a water dragon out of thin air, and pounced directly towards the pile of rubble formed by the monster like a waterspout.

There was a snort, and more white smoke rose as if cold water had been poured on red-hot charcoal.

And when the water dragon pounced, a small stone man only as tall as an ordinary person's waist suddenly appeared from the rubble, and he was about to run towards the entrance of the underground cavern.

But the other party's flexibility is only compared to ordinary people, for transcendents, especially those in the physical arts, this speed is not powerful at all, and they are banned in place by Gao Jingfei's controlled airflow.

Then Gao Jingfei waved his hand and released a golden flame, enveloping the entire little stone man, and within a few breaths, the monster turned into a pile of ash and fell to the ground, leaving only a crimson crystal still in place.

With a wave of his hand, he took this crystal in his hand, this should be a lava core condensed in the body of the lava monster, this thing looks very similar to the earth fire crystal, but the level is one step behind, at most it is a spiritual treasure of the red transcendent front.

And the Earth Fire Crystal, both in terms of usefulness and value, is no less than a golden legendary-level magic weapon.

"Not bad!" Gao Jingfei nodded with satisfaction.

Just use this to replace the flame fate true blood from the King of Fighters world that was placed at home as a Five Elements Lost Array formation formation, and after that thing got the Earth Fire Crystal, he now has an idea and has another use.
