In the black slave's story, the forbidden land he spoke of was in this lake, and as long as you entered this lake, you could find the location of the underground ruins.

But in the Black Death Swamp, lakes like this one are the most dangerous, because no one knows what will be in them.

There's a good chance that there will be some terrifying blood beasts hidden.

And in the Black Death Swamp, the penetration of the warrior's perception is extremely weak, and he can't spy on what will be in this lake at all.

Therefore, even a sixth-order martial artist would rarely dare to venture into this kind of lake, unless he died.

It was also after an accident a few years ago that the black slaves entered the lake and saw the underground ruins.

"Let's take a look. ”

Qin Chen did not hesitate, and directly released the soul power, in a place like the Black Death Swamp, the soul power was more reliable, and the penetration of the soul power was much stronger than the spiritual power.

It's just that what makes Qin Chen puzzled is that this lake is extremely ordinary, no matter how he investigates, it is just an ordinary lake, and there is no trace of the ruins at all.

"The black slave should not lie to me, if what he says is false, it will be debunked as soon as he arrives. ”

Thinking of this, Qin Chen didn't hesitate, his body shook, and he rushed directly towards the lake.

"Whoa!"

The water splashed violently, and Qin Chen felt that he was cold, but the next moment, he no longer felt the resistance of the water, as if he had entered a void.

Qin Chen immediately understood that this was indeed a high-level concealment formation, and even the level was so high that it had to be above what he imagined, otherwise he wouldn't fail to see a clue.

As far as the eye can see, where is the bottom of the water in front of him, what appears in front of him is really an underground world.

The sultry environment, the rich true qi of heaven and earth, and the hard black rocks around it, growing craggy and abruptly, are completely different from the feeling of the black death swamp.

But Qin Chen understood that this place should still be in the Black Death Swamp, but in the underground of the Black Death Swamp.

After falling to the ground, Qin Chen sighed in his heart, the pervert who arranged this hidden formation guy, being able to arrange such a high-level hidden formation is definitely not an ordinary formation master, or even a modern formation master, this place looks like it has been around for many years.

It's just that Qin Chen is puzzled, since this guy has arranged a concealment formation, why doesn't he arrange a defensive formation?

With the cultivation of that formation mage, even if only an ordinary defensive formation is added, let alone a black slave, even if a seventh-order martial king enters the lake, he will only rush into the real lake, and will not come to such a place.

The underground world that appeared in front of Qin Chen's eyes was not big, it was like a huge square, only about ten miles in radius, but inside, there were some strange rocks everywhere, and huge stone pillars stood in it, which was extremely messy.

And in the center of this underground world, there is a small pond that has dried up, and in the center of the small pond, there is actually a brown boulder towering there, and in the center of the boulder, there is a small groove.

Qin Chen immediately understood that this should be the place where the black slave found the Qinglian Demon Fire and the Black Gourd.

At the beginning, the black slave had told him that his Qinglian Demon Fire was found in the groove on this black stone platform, and the black gourd was also near the Qinglian Demon Fire, and there was even a method to control fire refining insects and other spirit insects in the black gourd.

Qin Chen came to the vicinity of the pond, ready to take a look at the environment, and suddenly his eyes froze, because he found that there were extremely subtle prohibitions on the stone platform.

These prohibitions are very unique, and they are hidden on the brown boulders, and they are absolutely impossible to find unless they are extremely strong prohibition masters.

Even if Qin Chen hadn't learned about a new forbidden refining method in the ancient southern capital, he might not have discovered such a prohibition.

How could there be a ban here? Qin Chen's heart was immediately shocked.

The appearance of the ban means that this place is not naturally formed at all, so in this way, this Qinglian Demon Fire and Black Gourd were all placed here, but what is the purpose of him putting them here?

Qin Chen wanted to find a clue from these prohibitions, but he observed for a long time and didn't find the slightest clue, which made him feel strange that these prohibitions were actually a cultivation prohibition.

And the source is the pond below.

That is to say, someone put the Qinglian Demon Fire and the Black Gourd here, and then laid a ban, using the spiritual water in this pond to cultivate the Qinglian Demon Fire and the Black Gourd.

It's a pity that the spiritual water in this pond has almost dried up, and I can't tell what kind of spiritual water was once in this pond.

And what made Qin Chen even more puzzled was that the prohibition on this brown stone platform, in addition to the function of cultivation, actually had no defensive function.

According to the terrifying formation outside the lake and the prohibition here, the person who left the Qinglian Demon Fire only needs to arrange a defensive formation or attack the prohibition at will, let alone the black slave, even if a seventh-order martial king comes here, he can only have hatred.

The other party definitely has this strength.

But not only did the other party not set up a defensive formation, but even placed the green lotus demon fire and the black gourd directly here, as if they were about to be taken away by the person who found it, and also left a method for refining the spirit worms in the black gourd, which made Qin Chen unable to understand the reason.

Is this clearly cultivating the Blue Lotus Demon Fire for someone else, or is that person so arrogant that he thinks that no one can find out about this?

After thinking about it for a while, Qin Chen, who couldn't figure out the reason, didn't bother to think about it, and continued to walk forward.

The most important thing for him now is to find the bitter rhyme.

"It should be here. ”

After only a few kilometers of advancement, Qin Chen discovered the place that the black slave had said.

This is an extremely flat sandy and gravel land, but on the periphery of the sandy and gravel land, there is actually a maze and a killing array.

Moreover, this maze and killing array are actually only fifth-order formations, and they are only fifth-order medium formations.

A faint smell of elixir passed out from that formation, and Qin Chen immediately knew that Ku Yunzhi was definitely still in this formation and had not been taken away.

And this taste is clearly the smell of Kuyunzhi that has matured, and it has not been long before it has just riptified.

Qin Chen was immediately pleasantly surprised.

What he was most afraid of was that someone had already taken Ku Yunzhi first, but now it seems that there is obviously not yet.

For Qin Chen, he could even arrange a fifth-order peak formation, and if he wanted to break a fifth-order mid-level formation, it would be no problem at all.

It's just that the appearance of these two formations made Qin Chen's heart sink.

Because in the black slave's inform, there is no formation here at all, otherwise with this maze, the black slave would not have discovered the bitter Yunzhi inside.

Apparently, there were other people who came here after the slaves left. =

And this person has arranged a maze and a trapped formation here, obviously because Ku Yunzhi is not mature, or for other reasons, he can only leave here temporarily, and at the same time lay out a formation to prevent others from discovering Ku Yunzhi.
