Since Zhang Fan and the others entered this underground cemetery, more than ten days have passed, and many people are still wandering, avoiding the thick black fog and various demonic beast mechanisms in this space, and it seems that no one can successfully find the location of the so-called strong cemetery.

And on a certain pond that no one noticed, a huge black whirlpool that appeared at an unknown time was rotating mightily on the surface of the water, and if you looked closely, you could see that the huge and sharply rotating black whirlpool was not any other gas, and it was the most dangerous black fog in this space at the time.

A large amount of black mist was constantly being sucked from the surroundings, like black waves, surging and surging to make people tremble, but when they came to the vicinity of this pond, they were controlled by a more powerful suction, and they couldn't help but spin in one direction.

I saw that the black fog vortex was getting bigger and bigger, gathering more and more densely, and the sound of thunder and explosion was constantly rumored from it, and the black fog wave gathered in this pond at this moment was so huge and magnificent, yes, there was nothing to approach within a few miles around, and the people scattered everywhere had discovered something strangely.

That is, the surrounding black fog is much rarer than at the beginning, and a large amount of black fog seems to be flowing towards a fixed convenience, which makes many people feel a lot easier, at least when facing those powerful beasts underground, they don't have to worry about the invasion of black fog at all times.

And in this pond that is only a few hundred meters in circumference, a black figure that is completely covered by black fog is sitting in it, and when a large amount of black mist gathers on him, it is like a mud cow entering the sea, magically disappearing, as if this figure is a small but huge capacity exhaust fan at this moment, greedily and uncontrollably absorbing the surrounding black fog.

That's right, this black figure is Zhang Fan, who began to sit here and absorb the black fog more than ten days ago, after more than ten days, he said that the black fog absorbed is not to mention how much, I am afraid that Zhang Fan himself can't say clearly, the only thing he knows is that with the absorption of the black fog during this time, the demonic energy in his body can be said to be unprecedentedly thick.

If you want to describe it, the demonic energy in Zhang Fan's body before is like this small pond under him, although it has a powerful monster energy like the Demon Fetus Stone, but after all, it still has a lot of limitations, but now it is different, the Demon Qi in Zhang Fan's body is like an endless river, even if there is no Demon Fetus Stubborn Stone in his body, Zhang Fan feels that the demonic energy in his body will not weaken at all.

And what surprised him the most was that the powerful thunder power contained in these black fogs also played a great role in his thunder power cultivation, Lei Dan, who was still the size of mung bean sesame seeds before, under the cultivation of these black fog thunder power, was already stronger than before to the size of a little thumb, and the strength of Lei Dan in his heart, yes, Zhang Fan's Nine Heavens Heart Thunder Decision has improved a lot, and Lei Duel, who has been staying in the seventh layer, also stepped into the eighth layer with this opportunity.

Between gestures, with every exhale and inhalation, Zhang Fan felt that his body was filled with rich thunder and demonic energy, and his own spiritual power was also under the support of these two forces, and he directly entered the four-star intermediate level.

Feeling the improvement of his strength, Zhang Fan naturally couldn't help but be overjoyed, "I didn't expect the effectiveness of this black mist to be so great, my demonic qi is more stable, Lei Jue has also entered the realm, and even my spiritual power has also increased by one star, which is really an unexpected huge gain, hey, it's just a pity, these black fogs seem to have a limit of utility, this is already the biggest effect, and it has little effect if it is absorbed again." ”

Just when Zhang Fan wanted to stop absorbing the black mist, he only heard some chatting and laughing not far from outside the pond.

"I didn't expect you to be so funny, Childe, I really can't see it. ”

"Well, am I supposed to look like that kind of person? If so, that's too boring, right?"

Zhang Fan listened to the voices of these two people, and immediately recognized the voice of one of them, "This, this voice is ........."

The two people outside suddenly stopped, "Wait! Looks like we're in trouble!"

"Well, it seems so, so much black fog has gathered in this place, it seems that there is something here that attracts them. ”

"No, these black fogs are not attracted, but seem to be forcibly sucked over, no matter what kind of strange beast is in the black fog vortex, I'm afraid it is not easy to deal with!"

Suddenly, the black fog, which was originally highly gathered, turned out to be in a commotion, and in the blink of an eye, it began to be like a frightened bird, a large amount of black fog began to disperse, and a wriggling black figure appeared in front of the two, and the man hurriedly protected the woman, "It's not good, it can even absorb the black fog, that person is afraid that his strength is not low, wait a while, girl, you run directly, don't pay attention to me, I'll drag him!"

But in the next second, the man was completely stunned, because the woman behind him completely ignored his words, and ran directly towards the figure where there was still a lot of black mist, "Wait! Don't go over, girl, it's dangerous!"

"Fan!~"

Yes, I came to Zhang Fan at this moment, and the woman who hugged Zhang Fan was none other than the young Caiyu who was besieged before, and was rescued by the young Caiyu, who was walking all the way, the black fog on her body was dissipated, and she felt the beauty in her arms, Zhang Fan couldn't help but hold Fang Yu with one hand and put it on her head with the other, for more than ten days, Zhang Fan was also worried about Fang Yu's safety all the time.

"Yu'er!~"

And the young Caiyu, who had been watching these two people from the sidelines, also knew that it was only at this moment that he reacted, "It turns out that this person is the person that Miss Fang Yu has been thinking about all the way, but why did this person come out of the black mist just now?"

Zhang Fan looked at the tears in front of him and almost couldn't help it, and the tenderness in his heart was also undulating, "What's wrong?

Fang Yu shook his head, a pair of tender eyes were looking at Zhang Fan all the time, as if he was afraid that he would disappear from front of him again, "Yu'er, are you okay these days, you haven't encountered any danger, right?" But seeing the bandage on Fang Yu's arm, Zhang Fan also realized that Fang Yu had been hurt for a while, and he was furious in his heart, "Yu'er! Are you injured?"

When Fang Yu was about to tell Zhang Fan the whole process, he saw Zhang Fan seeing the young Caiyu on the side one by one, I don't know if it was out of anger, Zhang Fan subconsciously thought that it was this Caiyu that hurt Fang Yu, "Hmm! Is that you?!"

Zhang Fan didn't say a word, he directly raised his right arm towards the young Caiyu volley, and shook it suddenly out of thin air, and there was still a lot of black fog left around him that was manipulated in an instant, and all of them bombarded towards the young Caiyu.

"Who the hell is this person!Not only can he absorb the black mist, but he can also control the black mist?!" Caiyu hurriedly said: "Brother Tai, don't don't, calm down first, I didn't hurt Miss Fang Yu, you misunderstood!"

Fang Yu also hurriedly explained to Zhang Fan: "Fan, it's really not him, it was some people from the Earth Demon Clan who injured me ten days ago, and he rescued this son." ”

Hearing this, Zhang Fan stopped his control of the black fog, in fact, Zhang Fan was also a little surprised by the control of the black fog, and he had just noticed it a few days ago, he thought about it and thought that maybe it was because he had absorbed so much black fog power, and maybe he had also built some connections with them at some level.

"Yu'er, is it really this person who saved you?"

"Well, it was really he who saved me, otherwise I might have been killed by those people from the Earth Demon Clan. ”

"So that's the case, I'm sorry, this brother, thank you for reaching out to Yu'er, Zhang Fan is here to thank you. Although he said thank you, Zhang Fan was still a little vigilant in his heart for this man of unknown origin who still came with Fang Yu with such a smile and a smile.
