The black fog slowly faded as the distance narrowed.

It's not that the black fog is changing, it's that people's vision is slowly adapting.

"Here...... Is it an oil refinery? ”

Ning Tian looked at the scenery in front of him and couldn't help frowning.

Looking at the mountain, this place was originally shrouded in a black fog, but when he came closer, Ning Tian found that it was not black fog, but black smoke constantly gushing out from the ground.

On the ground, a layer of greasy things, like heated asphalt, is still bubbling up, this bubble is also black, a little hungry keeps getting bigger, when it grows to the edge of its own tolerance range, it suddenly bursts, and the black grease around the bubble splashes down, but the black smoke contained in it quickly blends into the air, and the other black smoke is instantly mixed together.

"Good dragon, let's go down and have a look, okay?"

After speaking, Ning Tian didn't wait for the bone dragon's statement at all, and directly controlled it to fall down.

"Hey! I say! If you have an opinion, you can say it! What kind of temper is this!? ”

When the bone dragon was close to the ground and was about to touch the ground, it suddenly refused to land like crazy, and regardless of Ning Tian's control, it flew back into the air desperately, and Ning Tian scolded his mother.

"Grandma, judging from your performance, there seems to be something strange in this, okay, okay, I won't force you, then let's just wander around in such a high place, see how big this area is, it shouldn't all be like this."

This time, the bone dragon had no objections, and obediently began to fly in the air.

The floor is full of this substance, but judging from the bubbling location, the situation must be uneven. There should be a lot of pool-like places where bubbles will bubble. However, such places are densely distributed and uneven in size, from small places being less than a meter in diameter to large places about the size of a small lake.

After looking around, the area is not very wide, and about five thousand meters ahead is the end of this terrain. But this bone dragon was reluctant to land, which couldn't help but make Ning Tian muttered in his heart, there must be something wrong here, otherwise how could this dragon clan be afraid.

"It's useless to think too much, I'd better go back and join others, it's impossible to go all in the air."

Thinking of this, Ning Tian turned the faucet and began to fly back in the direction he had come from.

"Oh, you're not slow."

Ning Tian returned to the team and said pretending to be surprised.

At this time, the team had all reached the front of the two large stone pillars at the bottom of the mountain.

These two stone pillars are more than ten meters high, standing there, looking very much like two doorposts, but unfortunately, there is no door.

"You say, we've been waiting for you here for a long time. Didn't you say you'd come back just by taking a look? Why are you only coming back now? ”

Gu Xuan'er looked at Ning Tian, who was still hovering in the sky, and said with his head held high.

"I'm not here to find a way for you. Didn't you stop when you noticed something was wrong ahead? The distance of several kilometers ahead is that kind of road, and I'm thinking about how we can get there. ”

Ning Tian pointed not far away and said.

Not far from the stone gatepost was the melted asphalt-like pavement, and at this time, the strong smell of rubber was filling the air, and after inhaling, the whole person felt bad. My throat was very dry, and I always felt like I was vomiting, but I couldn't vomit it out.

Gu Linger said tangledly: "We also saw it just now, in this area, these mounts seem to be reluctant to set foot in this area, but most of them are land mounts, and there is no way to fly over, what can I do!" ”

Gu Biao looked around and said reluctantly, "Or, let's see if there are any other roads, right?" You should be able to get around it. ”

"I've seen it all, this method is not very advisable, the extension of the left and right, too wide, if you want to detour, it will take too long. Also, as you have seen, this even the gate pillar is a reminder that this road is here, if we don't go from here, it will be known by others in the future, wouldn't it become a joke! ”

Ning Tian didn't consider their proposal at all, this was not just a matter of face, Ning Tian always felt that since this route was arranged like this, then there must be a reason in it, if he really detoured, it would not be impossible, but wouldn't the benefits be lost.

Besides, their power has only been established for a short time, and this momentum must not be weak, so they just came in and began to walk around, and if something happens in the future, who will go up!

After speaking, Ning Tian controlled the bone dragon to fall to the ground, anyway, this bone dragon didn't want to set foot in it, he simply took it, and then copied his weapon and walked to the front of the team.

"I've tried it just now, and the mounts don't want to get involved directly, there must be something strange about it, and since they're afraid, it's up to us masters to make the way for them. I'll try it first. ”

Saying that, Ning Tian walked inside in small steps. Although the words were arrogant, Ning Tian'er was still very cautious, and the steps under his feet did not open and close, but slowly and tentatively moved forward.

The feeling under his feet was sticky, this thing was indeed the same as asphalt, but what made Ning Tian more relieved was that as he estimated, in the area where there was no bubbling, the depth of this asphalt was also tightly below his neck.

"Gollum~Puff~"

Ning Tian's ears kept thinking of the sound of bubbles rising and then bursting. The surrounding temperature is not high, but there is always that feeling of steam and difficulty breathing, it feels like being in a sauna, and after a while, Ning Tian feels that his body is covered with a layer of fine sweat, and his pores are wide open at this time, but he can't breathe fresh air, and a pinprick-like feeling immediately spreads throughout his body.

"Hmmm! Well! ”

Walked to a bubbling place, the scope of this area was very small, about a meter in diameter, Ning Tian stabbed it with his long sword, there was no reaction, this began to stir up in it again.

"How can this section have the meaning that the monkey is stirring up the water inside the eagle stream and wants to provoke the white dragon horse."

Ning Tian could still think of these things at this time, it could not be said that his heart was not big enough! Just now, the bone dragon was unabashedly afraid of this, but he had a feeling of playing with water at this time, if he had to use a more appropriate adjective to describe his state at this time, then there should be no word more direct and appropriate than 'to die'.

He seems to have forgotten what he used to say: If you don't die, you won't die! (To be continued.) )
