Following the traces left by the cat demon, Qin Yu chased all the way to the mountains.

But then it was all the mountain road, and the horse was useless, so Qin Yu tied it to the foot of the mountain, and he himself went up the mountain on foot.

The purple demonic aura appears and disappears from time to time, and it is all on a remote path.

In this kind of rainy weather, Qin Yu was very struggling to follow, and after a while, his whole body was completely soaked.

Fortunately, the cat demon didn't seem to notice that there were still people following him, so he didn't go around in circles, but went all the way to his cave.

After crossing the two hills, the storm gradually subsided and turned into a drizzle.

The thick dark clouds gradually dissipated, and the moonlight once again dispelled the night.

As Qin Yu continued to chase in, the purple mist became thicker and thicker.

Just as he followed the trail of the purple mist and turned over a mountain again, the terrain of the mountain in front of him completely changed.

Turning over this mountain, there is a basin with a huge drop in front of you.

If it was just like this, it was not enough to surprise Qin Yu, what was even more unimaginable was that there was an extremely amazing rich yin qi in this basin.

In ordinary places, this kind of yin qi cannot be gathered, and only in the most yin places can it be so. Moreover, this kind of place where the yin qi is rich is usually occupied by powerful evil spirits.

What Qin Yu didn't understand was that if there was an evil spirit here, the yin qi would not be so pure, and it would inevitably be mixed with the evil qi.

This place of gathering yin is definitely weird!

Thinking of this, Qin Yu was shocked in his heart, and did not rush down, but carefully observed.

Sure enough, after about a cup of tea, Qin Yubian found that these yin qi actually gathered but did not disperse, and it seemed that he was imprisoned here.

Not only that, but what is even more surprising is that these yin qi are actually consumed within themselves, and every time the yin qi is thick to a certain extent, it will suddenly become thinner.

And it will take a certain amount of time to return to the previous intensity, and it seems that the time is not short.

Seeing this situation, Qin Yu couldn't help but be amazed, and he was even more sure of what he thought in his heart, this place was definitely not ordinary, and it was even arranged by a master.

Just as Qin Yu was thinking about this, at the edge of the place where the yin qi gathered, a purple shadow took advantage of the faint moment at this time, and a fierce man pierced into it and disappeared inside.

Qin Yu, who watched it, couldn't help but be stunned, but soon, he roughly understood what was going on in his heart.

It seems that this cat demon is cultivating with yin qi here, but the previous yin qi is too strong, so it doesn't dare to go in, but waits for this yin qi to be weak before running in.

The cat demon did this, but it allowed Qin Yu to save the opportunity to take risks.

As long as you stay here and observe carefully, and see what the situation of this cat demon is, you can probably guess the danger level of this place.

...

Sure enough, an hour passed, and the yin qi below became thicker.

The cat demon who went in before returned the same way.

It can be seen that this cat demon does not seem to have developed spiritual intelligence, follows animal instincts, and only takes a safe path, which makes Qin Yu feel a lot more relieved.

If you don't have intelligence, it's easier to deal with.

And judging from the appearance of this cat demon coming out in time, the situation is similar to what I guessed before, after the yin qi inside is rich to a certain extent, even this kind of demon who cultivates with yin qi does not dare to stay in it for long.

However, if it were a different person, I am afraid that it would be half an hour at most.

Figuring out the situation, Qin Yu still didn't move, waiting quietly.

It wasn't until two hours later, when a trace of fish belly white appeared on the horizon, that the yin qi was also rich to the extreme, and began to weaken slowly.

When the sky brightened, the intensity of the yin qi stabilized.

At this time, Qin Yu was also able to get a glimpse of the whole basin, only to see that there was a scorched land below without an inch of land, and there was nothing else.

Seeing this situation, Qin Yu was even more sure of his conjecture, this place was by no means naturally formed, but acquired.

Qin Yu thought about it for a while, and he didn't know what was going on in his heart, so it seemed that he could only wait for the evening to talk about it.

However, before that, the cat demon must be solved first, and no trouble can be left.

As soon as such a thought came to his mind, the cat demon just left from here.

Qin Yu followed, taking advantage of his unpreparedness, to kill the cat demon, and then returned to the hillside, quietly waiting for the arrival of darkness.

This place where yin qi gathers is very weird, if he doesn't figure it out, Qin Yu is a little worried in his heart.

Sitting all day.

It wasn't until after night that Qin Yu jumped down from the trunk.

Looking up at the sky, the moon was bright and the stars were shining, and it was a good weather.

The Heavenly Eye was cast again, and the yin qi of the basin below slowly began to gather again after nightfall, just like the previous two days.

And this time, it seems that under the influence of the moonlight, the speed at which the yin qi gathers is slightly slower than yesterday.

Last night, it was when the yin qi reached its peak that it began to slowly dissipate, but tonight, it began to decay to a certain extent while the yin qi was accumulating.

This process lasted for two hours, and the rich yin qi began to dissipate.

Qin Yu didn't delay, and immediately ran down.

When he came to the edge of the basin, although he could still feel the extremely strong cold aura coming towards him, it did not give Qin Yu a very uncomfortable feeling.

"Looks like tonight is in my favor."

Qin Yu muttered in an excited whisper, then took out a porcelain bottle from his bosom and poured out some special white powder from it.

This powder is extracted from the gallbladder of the demon snake, and within the sight of the Heavenly Eye, it will glow golden, and it is specially used to prevent getting lost.

The usage is also very simple, you just need to throw some every other way after entering the inside, and you can point out the direction.

When Qin Yu's body completely entered this basin, he instantly sensed that these yin qi were wrapping himself, and along the pores of his body, he began to invade along the meridians.

After a moment of effort, some frost began to appear on the surface of Qin Yu's body, as well as black dirt forced out by the "qi" in his body, which were all yin qi that had invaded his body before.

With the qi of literary luck in the body, for a while, these yin qi will not be able to cause any harm to Qin Yu, but if it is a long time, it will be difficult to say.

To find out the situation as soon as possible in a limited time.

The wind was blowing under Qin Yu's feet, and he began to wander around this large basin, his eyes quickly looked around, not letting go of any suspicious places.

As he entered the hinterland deeper and deeper, Qin Yu also began to notice that something was not quite right.

During the day, it was clear that there was a scorched earth underneath it, and there was nothing, but now, these bones appeared for no reason.

It can be seen that this place has been appearing for a long time, and even these bones have become yin objects after accumulating in the yin qi over time.

Although these bones have completely decayed, if you look at them with the eyes of heaven, you can still see the position and appearance of these bones before they disappeared.

Qin Yu's gaze glanced at these skeletons, and he didn't stay longer, but continued to walk inside.

But the further you go inside, the more bones there are.

Not only that, but some wandering souls even began to appear.

When Qin Yu first started, he was also taken aback by this situation, and he almost had to do it directly. It's just that when he saw a soul floating in front of him, he didn't attack.

When I was suspicious, I couldn't help but observe.

It soon became clear that although these were souls, they were more like air, wandering along a fixed route, and even if something stood in front of them, they would not avoid or attack, but walked straight along the route.

Seeing that there was no threat, Qin Yu didn't care about it.

But just after avoiding these soul bodies, an ethereal voice suddenly came from all directions.

"How many years have passed, and finally my human race has stepped into this place, Xiaoyou, please come forward and talk about it."

As soon as the words fell, the yin qi around them began to tumble violently, and then, a dilapidated lantern glowing with milky white light slowly floated out.

The aura emanating from the lantern was a righteous qi, and when the surrounding people touched the white light, they avoided it like a snake and scorpion, and they rolled back one after another.

Qin Yu's face changed drastically, and he couldn't help but take two steps back.

The ghost that appeared in the voice, although this lantern exuded righteousness, did not completely reassure Qin Yu.

Seeing that Qin Yu hadn't moved for a long time, the voice sounded again.

"Xiaoyou don't have to be afraid, the old man doesn't have much time, please follow this lantern here."

"Seniors, I have no intention of breaking in, disturbing the seniors' Qing Xiu, and the juniors will leave."

Qin Yu bowed his hand, and after speaking, he turned around and left, not daring to stay for a long time.

But at the moment when Qin Yu had just turned around, the white light of the lantern suddenly skyrocketed, and several arm-thick chains flew out of it, tying Qin Yu up in the blink of an eye.

Before he could struggle, he was carried by the lantern and flew inside.
