"I need to get close to those soul fires to know why they still exist in the world." Sander said to Zhao Feiyu.

"Then let's take a look." Zhao Feiyu suddenly remembered the Soul Devouring Technique that Professor Gu Xuan gave him, but that Soul Devouring Technique was quite useful in the Divine Soul World, but in the real world, with Zhao Feiyu's current Divine Soul cultivation, he could not devour other people's Divine Souls at all.

Even the fire of the souls that inhabit the bodies of fallen beings cannot be consumed, and will be affected by the many negative breaths contained in them, let alone devour a soul with a complete mind.

Once forcibly devoured, it will inevitably be devoured by the mind of the god, and even fall into a state of madness, never to wake up again.

And the power of thunder is born to restrain the existence of divine souls, at this moment he already has a thunder spirit vein, if he uses the power of thunder to bombard the existence of those divine souls, he may be able to remove the negative aura in it, and then he can use the soul devouring technique to devour all those divine soul fires.

Zhao Feiyu hurriedly walked down the mountain, and the countless fallen creatures in the crack were all destroyed by the terrifying thunder power because of Sander landing in it, even if the body under control was turned into ashes, it can be said that there was not the slightest breath of life in the huge crack, only endless destructive power spread in it.

As for those fallen creatures outside the Fallen Spirit Mountain, their strength is far less than that of the fallen creatures in the cracks, and the so-called talents have never approached the corpse of the ancient dragon, and can only wander around the periphery of the Fallen Spirit Mountain.

Zhao Feiyu has now stepped into the realm of the middle stage of mortalization, and has opened up one of the most powerful spiritual veins, the Thunder Spiritual Vein, and is no longer dragged down by the Guiru Spiritual Vein.

So Zhao Feiyu wanted to try how powerful the power of Thunder was.

In front of a mountain rock tens of meters high, a demon beast with two horns on its head was wandering.

The demon beast's eyes were pale, and its body had dried up with flesh and blood, and part of its flesh had fallen off, revealing the white bones in it.

No matter how you look at it, it looks like the monster has been dead for many years, but it has been resurrected under the influence of some mysterious power.

Zhao Feiyu knew that all of this was inextricably linked to the ancient dragon's divine soul split, as well as the mysterious black mist that could devour flesh and soul and aura, all of which were caused by that split soul when it touched a certain forbidden realm.

But Gu Xuan never asked Xiang Sande, and Zhao Feiyu didn't dare to ask these taboo questions without authorization, for fear of causing unnecessary trouble.

Zhao Feiyu hid behind a mountain rock, revealing a pair of eyes to observe the demon beast.

After making sure that the demon beast didn't see him, Zhao Feiyu shook his right hand lightly and slammed towards the demon beast.

I saw a thunderbolt burst out from Zhao Feiyu's palm, exploding under the body of the demon beast.

Countless fragments of thunder spread, and all four legs of the demon beast were shattered into dust, and half of the demon beast's body was also shattered, lying on the ground and writhing.

Zhao Feiyu hurriedly ran to the demon beast, only to see that half of the demon beast's body had been shattered, revealing all kinds of withered internal organs, and there were only some bone stubble left on its four legs, which could no longer support the demon beast to continue walking.

Zhao Feiyu pinched his nose, and the body of the demon beast emitted a rotten stench, which made Zhao Feiyu feel a burst of nausea.

"Damn......" Zhao Feiyu muttered, "The power of the thunder is still too strong, I have been very careful to control the power of the thunder, I originally just wanted to break the four legs of the demon beast, but I didn't expect that even half of the body was broken." ”

The beast's pale eyes began to dim gradually.

A wisp of divine soul fire was pulled out by Sang De and floated in front of Zhao Feiyu.

A moment later, a thunderbolt flickered, and the flame of the divine soul instantly turned into ashes and dissipated into the world.

"I see." Sander said slowly, "These divine soul fires are all divine soul breath that escaped after I fell into a deep sleep at that time, and these divine soul breaths have evolved into what they are now. ”

"I've been asleep for so long, and I don't know many things." Sander said slowly.

"Then can I devour these divine soul fires?" Zhao Feiyu hurriedly asked, he knew that the cultivation of the Divine Soul was extremely difficult, and improving the cultivation of the Divine Soul was extremely important for a monk.

"It can be devoured, but it depends on whether you can get rid of the negative aura in it, otherwise you will fall into a situation where you go mad." Xander replied.

"Then I'll try it quickly." Zhao Feiyu once again found the fallen creatures who wandered alone.

"Boy, you see that your divine soul aura is still very powerful in the same realm." Sang De said slowly, "It is necessary to far surpass the divine soul cultivation that a mortal realm monk should have, and even be able to compete with a Xuan Realm monk." ”

"And ......," Sander muttered, "there seems to be an aura in your soul that I am very familiar with......"

"No, no." Zhao Feiyu hurriedly replied, "It must be the reason why you are in my soul sea, so I feel like this." ”

"Really?" There was a thoughtful hint in Nasander's words.

"There are two fallen creatures fighting ahead!" Zhao Feiyu saw two souls flickering in front of him, and instantly rushed towards the two souls fires as if he had found a life-saving straw.

After crossing a black rock, Zhao Feiyu saw the two creatures inhabited by the fire of the divine soul.

It was a Terran monk, corrupted by the black mist and turned into a fallen creature, and the robe on his body still looked quite extraordinary.

The fallen creature had a long sword in his hand, but all the aura of that long sword had disappeared and turned into a mortal iron.

Zhao Feiyu looked carefully, and saw that the right hand of the Terran monk holding the long sword had already turned into a white bone.

Obviously, this Terran monk's cultivation during his lifetime must have stepped into the realm of the Xuan Realm, otherwise he would not have been eroded like this by the black mist outside the crack.

It's just that no matter how powerful the monk is, he can't resist the terrifying power of the black mist, and he has become what he is now.

But the monk didn't seem to have forgotten to fight, and even though his hands had turned to bones, he still fought with his sword.

The monk was fighting a monster beast in the shape of a giant bear, and the monster beast was also eroded by the power of the black mist, and degenerated into what it is now.

Because the blood and qi of that demon beast were all dried up, it was impossible to fight as if it was alive.

I saw that the monk's sword was inserted into the right eye socket of the giant bear, piercing through the head of the giant bear demon beast.

The giant bear monster roared, and its giant claws slammed into the body of the Terran monk.

Only a cracking sound was heard, and the Terran monk's body instantly collapsed, turning into a pile of dry bones.

And on the hilt of the sword inserted in the giant bear's skull, the Terran monk's right hand, which had turned into white bones, was still tightly gripped, and did not let go.

Seeing such a scene, Zhao Feiyu couldn't help but sigh and sigh at the cruelty and ruthlessness of the cultivation world.

On the path of cultivation, I don't know how many living beings have turned into dry bones, and perhaps no one will be able to reach the end of the path.

And the divine soul fire in the heads of the two fallen creatures slowly floated out, levitating above the corpses of the two fallen creatures.

Zhao Feiyu's hands were quick, and he hurriedly urged a trace of thunder power to blast towards the two pale divine soul fires.

After that trace of thunder power came into contact with the Divine Soul Fire, the Divine Soul Fire instantly collapsed, and it couldn't withstand the power of the thunder at all.

Seeing such a scene, Zhao Feiyu had to sigh lightly.

"It seems that my ability to control the power of thunder is still too weak, and this is already the smallest amount of thunder power I can do. If these Divine Soul Flames can't even withstand this kind of thunder power, then there is no way for me to just eliminate the negative aura in the Divine Soul Fire without harming their essence. Zhao Feiyu couldn't help but sigh.

"It's not as simple as you think, young man." Sander's voice sounded in Zhao Feiyu's mind, "These divine soul breaths have gone through countless years, and they instinctively want to simulate their original form, although you look at them like the form of divine soul fire. But in the final analysis, they are essentially just the soul energy emitted by the divine soul, and they cannot be compared to the divine soul fire at all. And with your current form of divine soul, you can't devour the fire of the divine soul at all, all the soul qi of the divine soul turns into the fire of the divine soul, and your way of belonging to the following is not feasible. ”

"Is the Divine Soul Fire so powerful and mysterious?" Zhao Feiyu's words were full of doubts.

"Of course." Sander explained, "That Divine Soul Fire is not yet the realm you have access to, and it is useless to say so much to you now, after all, you haven't even opened up your Divine Sense right now. ”

"Okay." Zhao Feiyu could only nod slowly, "Sure enough, sometimes taking shortcuts doesn't work." ”

Zhao Feiyu slowly raised his right hand, and a cluster of flames rose instantly, exuding bursts of scorching aura.

Zhao Feiyu threw it lightly, and threw the flame on the Terran monk who had turned into a pile of dry bones.

Those flames fell on the dry bones of the Terrans, and they were extinguished in an instant after only a few breaths of existence.

Zhao Feiyu's eyes narrowed slightly, as if he understood something.

Obviously, in the Fallen Spirit Mountain, any aura will be swallowed and absorbed by the mysterious black mist.

The flame that Zhao Feiyu urged was contrary to the power of the black mist, and was instantly swallowed up by the black mist.

If he wanted the flame to continue to burn, Zhao Feiyu had to use the aura in his body.

However, once this method is adopted, the aura induced by Zhao Feiyu is very likely to cause the black mist to move.

If the black mist began to devour Zhao Feiyu's aura and flesh and blood, then Zhao Feiyu would not have any resistance at all, and would be instantly drained of all his power and turned into a dry corpse.

Seeing such a scene, Zhao Feiyu had to sigh lightly.

He originally wanted to burn the bones of the Terran monk who had turned into dry bones to ashes as a sign of his obsession with the Terran monk.

But in this mountain of fallen spirits, only death exists forever.

Zhao Feiyu slowly turned around and left, and several air currents rushed out of the black mist in an instant, and a thick bone spear was instantly nailed in front of him.

If Zhao Feiyu stayed for a while, he would be instantly pierced through his body by the bone spear and nailed to the spot.

"Damn it!" Zhao Feiyu's expression changed, and he hurriedly retreated behind him.
