These black fogs are not at the same level as the previous white fog at all, and the previous white fog can at least rely on this physical power to attack and force it back, but the rich black fog in front of me that I don't know where it came from, but no matter how everyone bombarded, it was attacking everyone without retreating.

"This, where did all this black fog come from? Why can't you force it back?"

"It's all close to it, and that person is close to it just now!"

All of a sudden, in the underground space of Nuoda, everyone scattered and fled like frightened birds, and Zhang Fan and others were also scattered by the flow of people who fled in a hurry, looking at the black fog around them that was getting more and more approaching, Zhang Fan couldn't care about finding others, so he had to leave the range of the black fog first.

In such a hurry, everyone who entered this tombstone group almost fled in different directions, and at this moment, everyone didn't even have the strength to discern the direction, so they could only flee to a safe place as much as possible, because so far, once they were invaded by the black fog, the end would be only one death.

But what everyone didn't know was that these black fogs were dispelling them, no, it should be said that they were leading to the deadliest place in this underground demon domain, even if Zhang Fan had such spiritual power in the Guanyin period, he was unconsciously getting closer and closer to the cemetery of the strong in the central area at this moment.

Zhang Fan finally got rid of the pursuit of those black fogs after several hours of avoidance, but when he came back to his senses, there was no way to know where he was, and in desperation, Zhang Fan had no choice but to grope his way forward in this underground demon domain.

For those black fogs that came inexplicably just now, as if they appeared out of thin air, Zhang Fan couldn't see any clues about them, judging from the power of the demon youth who was devoured by the white bones of the city at a speed visible to the naked eye after the demon youth was directly devoured before, I am afraid that there is still some kind of terrible devouring power in those black fogs.

Although Zhang Fan himself also had the Spirit Devouring Technique, in the face of this kind of black mist power that he didn't know its origin inexplicably, he didn't want to risk sucking it into his body, and the end would be even more tragic than that demon youth.

It was another half an hour of slow progress, and at least there was no black fog around at this moment, but the increasingly dense water vapor around it still blurred Zhang Fan's vision a little, and in this damp underground space, Zhang Fan felt that the whole person was not good, and he just wanted to speed up his pace to find Fang Yu them.

"Ah~!"

Suddenly, in front of Zhang Fan, a terrible scream came like thunder, Zhang Fan couldn't help but be nervous, his steps accelerated and walked steadily towards the place of the sound, only to see a pond about a few hundred meters later, a young man who didn't seem to know which demon was already lying on the shore.

Although the clothes on the body are completed, all the flesh and blood are gone, leaving only a white bone on the ground, which looks extremely hideous and terrifying, seeing no one around, and there is no black fog in the eye, it is estimated that it is dispersed after attacking this demon youth.

Zhang Fan boldly stepped forward to check, only to see that there was nothing worth paying attention to on the demon youth, although he was a little immoral, and even a little disrespectful to the deceased, but in this kind of environment, Zhang Fan felt sorry for himself if he didn't rely on this opportunity to pick up waste.

After rummaging several times, he only found a demon spirit ring, although there are also hundreds of magic stones, but the rest are some low-grade demon treasures, and the value is not as precious as the magic stones, in desperation, Zhang Fan had no choice but to take away the magic stones inside, after all, scavenging also depends on his luck.

But when Zhang Fan squatted down to rummage through the deceased's things, in a corner behind him that he didn't notice at all, a cloud of black mist that seemed to have not completely collapsed, or was left by the large army, only half the size of Zhang Fan's body, seemed to be sneakily slowly approaching Zhang Fan.

Zhang Fan has the spiritual power of the Guanyin period, but these mist are all lifeless energy bodies, even if there is a slight energy fluctuation, in the surrounding environment full of riot energy, by the time Zhang Fan finds out, it will be too late.

"Not good!"

Although Zhang Fan found out, the speed of the black mist suddenly soared, and before Zhang Fan had time to dodge, it was already like a maggot attached to the bone, firmly attached to Zhang Fan's body, Zhang Fan was shocked for a while, after all, there were still living examples around him.

"Damn! These, they're so sticky, you can't get it down, are you octopus!

However, with the adsorption of the black mist, an extremely strong corrosive force kept impacting Zhang Fan's skin, and the crispy and numb feeling made Zhang Fan's heart beat for a while, but when Zhang Fan thought that he would be seriously injured even if he didn't die, the parts covered by the black fog did not undergo any erosion and change, which made Zhang Fan puzzled for a while.

"What's the matter?Could it be that the corrosive power of this black mist is useless to me?shouldn't it?I don't have any high-level protective spirit weapons on me?!"

Under Zhang Fan's extremely curious observation, he saw that in the black mist that kept squirming on his body, there was suddenly an extremely faint glimmer of light flickering in it, and coupled with the crispy numbness on his skin, not to mention how familiar it was, after a few thoughts, Zhang Fan suddenly had a bold guess.

In order to prove that his idea was right, Zhang Fan was bold and took the initiative to slowly probe his hands into this small black mist, his spiritual power was carefully shrouded, and under the patience and slowly perceived, Zhang Fan's face turned from worry to joy.

"I see! No wonder this black fog is ineffective against me, it turns out that what is in this black fog is not the power of erosion, but the dense and strong thunder force!"

But Zhang Fan thought about it, and seemed to take it for granted, after all, this black fog is also a kind of water vapor energy body, rich water vapor gathering, friction, will inevitably produce electricity, but what makes Zhang Fan not quite understand is that if it is natural, this water vapor still needs to go through several processes of condensation clouds, rain, and thunder before it can form thunder.

However, the black fog in front of him is completely insufficient to condense thunder in terms of the amount of water vapor or energy, when it can completely ignore these processes, it contains such a rich thunder power inside, and it can be seen from the almost instantaneous speed of these black fog eroded into white bones, how terrifying the concentration of thunder in these black fogs is.

Originally, it was supposed to be the effect of thunder penetrating the scorching, but because it was too dense and powerful, it turned out to be an illusion that people were alive and bone-hungry, and these black fogs were really a little weird.

However, for Zhang Fan, the situation in front of him is developing towards a situation that is extremely beneficial to himself, because those black fogs not only have a strong thunder power, but also a thick demonic energy, and the combination of the two forces is actually a rare tonic for Zhang Fan.

"I don't know how this black fog is formed, it is a combination of two powers, thunder and demonic energy, and I can use both powers, these black fog is not too much for me, no wonder those demon people just now will form the illusion of being rapidly eroded as soon as they touch the black fog, and the demons seem to be extremely resistant to thunder. ”。

In fact, when Zhang Fan remembered the story that Lian Qiong had told himself about the origin of the demon god and the demon race when he was in the Dragon Ruins Forbidden Forest before, he had already said that the demon race was the most loyal believer of the demon god who violated the way of heaven, and the confrontation between the demon race and the way of heaven would inevitably be ruthlessly punished by the way of heaven.

And the most commonly used and most powerful way of Heavenly Dao punishment is undoubtedly the Heavenly Thunder, just like when he participated in the newcomer ceremony in the Spirit Department before, or when his natal spiritual weapon Demon Shadow Bow was born, wasn't it all Heavenly Thunder?
