Lin Fei's current sensing ability is indeed very sharp, but it is extremely difficult to really sense the existence of Qingyanhuo.

You must know that the "Origin Fire" was born between heaven and earth, and was conceived by the laws of heaven and earth, so it is naturally very easy to integrate into the heaven and earth, and once it is hidden, it is not easy to discover its existence.

Why is the "Origin Fire" so rare? It's not because it's so hard to get, unless you have a great chance, otherwise you can't see the "Origin Fire", so how can you have the opportunity to merge with it?

Lin Fei had fused the Red Lotus Fire in his previous life, and he was very familiar with the nature of the "Origin Fire", and he also had a keen sense of it that was far beyond ordinary people, but after being reborn, this body was too young after all, and it was limited by the cultivation realm, so how easy was it to find the existence of the Blue Flame Fire in such a large lava lake?

Moreover, Lin Fei knew that there was not much time for him to really look for, after all, the battle between the Fire Spirit King and the cultivators could not go on forever, once they sensed that something was wrong in the lava lake, they were afraid that they would rush into the lava lake together, and the situation would be even more chaotic at that time!

However, since Lin Fei was planning to dive into the lava lake, how could he not have thought of a way to deal with it in advance? As he dived to the bottom of the lava lake, which was nearly a thousand meters deep, he immediately used the Subtle Pupil again!

At the bottom of the lava lake, there is fiery red lava boiling everywhere, not only the fire spiritual energy, but also a thick layer of magma can also form an extremely heavy pressure, if Lin Fei is not cultivating a true fire magic power like the Golden Crow Fire, with only his current realm cultivation, let alone looking for Qingyanhuo here, he can't even do normal stealth. And with the ability to enter the faint pupil activated, soon in Lin Fei's eyes, the appearance of the bottom of the lava lake changed.

Looking through the subtle pupils, the fire psionic energy seems to have turned into a fiery red spectral pattern, and it is easy to distinguish the subtle differences of the fire psionic energy by simply observing the depth of the spectral color. According to Lin Fei's observation, he quickly noticed that among the surging fire spiritual energy around him, there was a trace of unusual spiritual energy fluctuations, although this fluctuation was extremely faint, but the spectrum that appeared was many times higher than the frequency of ordinary fire spiritual energy!

This trace of spiritual energy fluctuations, compared to the lava lake, is like a drop of ink integrated into the entire lake of water, it should have been diluted to the point of invisible, but after all, it is different in nature, as long as you have the ability to observe the subtleties, you can still detect the existence of this spiritual energy fluctuation, and trace back to the source.

And such a special spiritual energy fluctuation, apart from coming from the Blue Flame Fire, is there any other possibility?

If it weren't for Lin Fei's possession of subtle pupils, if it weren't for the fact that Lin Fei had fused the Red Lotus Fire in his previous life and was very familiar with the "Origin Fire", even if he was now a Jindan stage cultivator, it would be impossible to discover the existence of the Blue Flame Fire in this lava lake!

It can be inferred from this that as long as cultivators above the foundation building period are restricted from entering the Flame Hell, then no matter who it is, unless it is the reborn Lin Fei who appears, it is impossible for anyone to find the existence of the Blue Flame Flame!

As for the moment, it is naturally the biggest opportunity that Lin Fei has encountered after his rebirth, and he must grasp it!

So Lin Fei continued to use his faint pupils, looking for the faint trace of spiritual energy fluctuations of the green flame fire, groped away from the bottom of the lava lake, and found a fire vent with earth fire spewing out at the bottom of the lake after a while.

At present, although this lava lake is formed by the convergence of more than ten lava rivers, there is still a fire vent at the bottom of the lake that communicates with the depths of the ground, but it is difficult to say whether the magma is poured down from the fire vent or another magma gushes out of the fire vent.

There is not only one such outlet at the bottom of the lake, and there is no difference at first glance, but under Lin Fei's subtle pupils, he can see a clear difference.

The other fire outlets, their spiritual energy spectrum is all fiery red, only the one that Lin Fei is concerned about, a trace of blue light emerges in the fiery red!

There is no doubt that if there is really a green flame, then it must be hidden under this fire!

The fire outlet was only the diameter of a fist, and it was definitely impossible for Lin Fei to get into it, but this was difficult for Lin Fei, only to see him condense the golden crow fire around him, turn it into a pillar of fire, and just drill into the fire outlet!

The fire of the golden crow is the quality of real fire, and if the fire encounters it, it will retreat, no matter how turbulent the fire spirit energy of this fire mouth is, it is impossible to compete with the fire of the golden crow, so it is natural to let the fire of the golden crow drive straight in.

Lin Fei controlled the Golden Crow Fire, and it would not dissipate until at least ten miles away from his body, if he really allowed the Golden Crow Fire to go all the way down, then it would not be impossible to penetrate the earth's core in one fell swoop. However, not far from the fire of the Golden Crow, a cyan flame burst out, and in turn swept towards the fire of the Golden Crow, and there was a posture of devouring the fire of the Golden Crow!

If other cultivators were here, even if the Golden Crow Fire was cultivated to a level where its quality surpassed that of Lin Fei, in the face of this sudden outbreak of green flames, he would be caught off guard and suffer a big loss. But Lin Fei was different, with the experience of fusing the "Origin Fire", how could he not have prepared in advance?

The Golden Crow Fire, which had originally condensed into the shape of a pillar of fire, instantly retreated backwards as Lin Fei's mind moved, and fled towards the outside of the fire outlet, as if he was afraid of the green flames.

For the Qing Yan Huo, it was hiding in such a place, and there was almost no chance of touching the foreign True Fire, and now that it was finally waiting for the Golden Crow Fire to appear, how could it be easy for it to escape? So the Qing Yan Fire almost did not hesitate to rush forward, and just rushed out of the fire mouth, intending to devour the escaped Golden Crow Fire.

It was also at this time that Lin Fei made a very astonishing move, only to see him pounce on him properly, and he actually faced the green flame with his own body!

How powerful is the "Origin Fire", if you directly contact the "Origin Fire" with your flesh and blood, you are not afraid of burning into nothingness in an instant?

Not to mention the "Origin Fire" like the Green Flame Fire, when Lin Fei removed the protection of the Golden Crow Fire, he couldn't hold out for too long in the lava lake with his physical strength alone, how could he stop the Green Flame Fire?

But what is surprising is that when Qing Yanhuo and Lin Fei's body just came into contact, Qing Yanhuo actually directly submerged into Lin Fei's body, but Lin Fei's body looked safe and sound, as if this Qing Yanhuo had no power!
