On the vast wasteland, a streamlined flying boat silently crossed the sky.

The black flying boat stopped in front of an inconspicuous canyon and hangs in mid-air.

Xia Rufei stepped out of the flying boat, took the Obsidian Flying Boat into the spiritual map space, and then walked carefully towards the canyon.

When he came to this crack, Xia Rufei's mental power quickly explored downwards. When his mental power extended to about one hundred feet, he had encountered obvious resistance. Obviously, inside this crack, it had a certain suppression effect on mental power.

This is a very common situation within the Qingpingjie ruins, which may occur whether in cities or in wilderness.

Perhaps the formations that were tens of thousands of years ago were still in operation, or perhaps the core formations in the entire Qingping Realm ruins had some disorder, so the situations in different regions were different.

Xia Rufei was not surprised either, so he carefully investigated within the reach of his mental power.

The deep cracks in the ground were quiet and nothing could be found, as if there was no living creature. However, on the mountain walls on both sides of the canyon, you could vaguely see the traces of sea water erosion that year, and there were even fossils of fish in some places.

According to the Black Dragon Remnant Soul, there were some dangerous undersea creatures in this crack back then.

These undersea creatures are naturally insignificant in front of masters of the Emperor level, but for someone like Xia Rufei who only has the Nascent Soul stage cultivation level, it is still quite a threat.

But now Xia Rufei can't find anything.

These tens of thousands of years have passed, and even the sea has disappeared. Those underwater creatures have lost their living environment and gradually disappeared over time. This is not impossible.

Although the underwater creatures here are different from ordinary marine creatures on the earth, they have actually become monsters or monsters, and those with strong strength can even reach the level of power, and they can survive even if they are separated from the sea. However, when Emperor Qingping killed Qingping Realm, it caused a violent shock in the realm. It is estimated that underwater creatures with lower cultivation will almost die in that wave of impact.

Those undersea creatures with high cultivation may also lose their habitual living environment, and the inability to absorb spiritual energy here to practice, as time goes by, they will slowly be destroyed in the dust of history.

Xia Rufei would not be very surprised if he did not notice the existence of those undersea creatures back then.

To be honest, if several aggressive big fish suddenly appear in this desert environment, it will feel even more inconsistent!

Xia Rufei pondered for a moment, then decided to go down to the crack of the ground to go to the cave he had just investigated and did not find the cave he mentioned by the Black Dragon Remnant Soul. He still had to continue exploring and searching slowly.

Just now, Xia Rufei had already simulated the range he could detect in the spiritual map space with invisible power. The black dragon remnant soul also drew a rough route for Xia Rufei based on his memory.

After all, tens of thousands of years have passed, and the terrain here has also undergone certain changes, so the black dragon remnant soul can only barely judge the location based on the memory of that year, and then plan a route for Xia Rufei with a relatively high probability of finding the cave.

If you still can't find it one or two hundred feet down the route, you have to consider adjusting the search direction.

Xia Rufei came to the crack and tried it. The crack on the crack here was only about one meter wide, and he could easily step from one side to the opposite side. However, it was very deep below, and the black squid was invisible to see the bottom, just like a monster with a big mouth, which made people feel involuntarily afraid.

Xia Rufei found that the ground crack could not support flying.

However, this is not a problem for him. The monk himself is much more agile than ordinary people. The crack in the ground is not smoothly vertically downward. The walls are uneven and there are many leverage points. In addition, there are many narrow places in the crack in the ground. Xia Rufei can even directly step on one side to support the body of the column, so there is no problem in climbing down.

However, Xia Rufei still took out a rope, and at the same time, he took out two very strong angle steel from the spiritual map space, and directly fixed the angle steel across the ground and fixed it to the ground. Then he used one end of the rope to tie a hang knot on the angle steel, and first hung the end of the rope.

This rope is four or five hundred meters long, and it is absolutely no problem to extend downward for more than one hundred feet.

Of course, this rope is actually just a backup. In some places where it is not easy to borrow force, you can use the help of the rope to climb down more easily.

In addition, once there is really any danger below, with this rope, Xia Rufei's speed of running upward can also be greatly increased.

This is the preparation for whether to be prepared for any eventuality or not.

After laying out the rope, Xia Rufei jumped into the crack of the ground. His legs kicked on one mountain wall, and at the same time reached out to hold the rope. The other hand also grabbed the bulge of the other mountain wall and stabilized his body.

Xia Rufei looked at the surrounding environment and terrain, then nodded secretly, and began to climb vertically down the crack.

From this position, the wide area is only more than one meter or less than two meters, while the narrow area is even only thirty or forty centimeters. Sometimes it takes a little force to squeeze it down.

Being in such a gap is actually very depressing.

Especially after the height continues to drop, the brightness in the cracks also drops rapidly. When you look up, you can only see a line of sky, but it is pitch black below and you can't see the bottom at all.

Even if a person without claustrophobia is in such an environment, he will definitely feel very depressed even if he is in a very close mountain wall on both sides.

Xia Rufei also felt a little depressed, especially when this section went downward, the crack of the ground became narrower and narrower, giving Xia Rufei the feeling that it was as if the crack of the ground would suddenly close and tie him to death inside.

After a while, Xia Rufei had climbed down for about a hundred meters.

He found that the mountain walls became a little wet just now on it, and all the way there was a very dry Gobi desert. There seemed to be no moisture in the soil, but as the height in the crack continued to drop, he felt a little wet when the mountain walls on both sides, and even could feel the moss.

The places with moss are naturally slippery and unrestrained. Fortunately, Xia Rufei prepared the rope in advance. With the help of the rope, he was not affected by the way down.

However, when the depth exceeds one hundred meters, the visibility in the crack is very low, just like a night when the clouds are thick, and after the moonlight is blocked, although it is not impossible to see your fingers, as long as you are a little further away, it will appear to be shady and cannot be seen clearly at all.

Although the purpose of a practitioner is far beyond ordinary people and can also see things in low-brightness environments, this is very unfavorable for Xia Rufei to find the stone cave. After all, sometimes mental power exploration may not be able to be discovered. Instead, the naked eye can be more intuitive, and the two methods have always been complementary.

So, Xia Rufei simply took out a headlight from the Lingtu space and put it on.

Of course, he did not turn on the headlight immediately and is now just a light environment, not completely invisible. Once he turned on the headlight, he would be completely exposed to the light. If there were still the undersea creatures of the past deep in the crack, his goal would be too obvious.

Therefore, Xia Rufei would not turn on the headlight before reaching the depth of the cave.

He continued to climb down the mountain wall, occasionally using ropes.

Xia Rufei discovered that the more he suppressed his mental power, the more he was. Although he climbed down more than 100 meters, his mental power only extended downward for twenty or thirty meters. Obviously, the deeper the lower the place, the stronger the mental power suppression power.

Although there is not necessarily danger, Xia Rufei is also very alert to this situation and dares not relax and explore the realm around him for a moment.

After all, in such a narrow environment, if an enemy suddenly attacks him next to or below, he will not be able to turn around and move, and it is easier to fall into a passive position than to be above.

Xia Rufei was cautious and climbed down slowly along the cracks.

The sides of the mountain wall were getting wetter. Now, almost all the moss was everywhere within reach of Xia Rufei. His hands became wet, and even there were water droplets condensed on the mountain wall.

While comparing the routes marked by the Black Dragon Remnant Soul, he also simulated the latest situation he found in the spirit map space, including his current location, which also marked out.

The remnant soul of the black dragon is in the spiritual map space, providing Xia Rufei with "navigation" services.

As Xia Rufei simulated more and more areas, the Black Dragon Remnant Soul has become more and more confident. He believes that the route he marked before should be accurate.

Before he knew it, Xia Rufei had already reached a depth of more than 300 meters. Because the cracks in the ground were not completely vertically downward, there was no sky above his head now. Similarly, the surrounding area was pitch black. If an ordinary person came here, he would definitely be unable to see his five fingers. Although Xia Rufei's eyesight was much stronger than that of ordinary people, he could only see a little outline of the mountain wall here, and the detailed situation could not be seen clearly.

According to the Black Dragon Remnant Soul, the Black Dragon's original treasure hid the storage magic treasure more than 100 meters, which was counted as more than 300 meters.

However, this range is relatively broad, basically from 330 meters down to 4500 meters, or even 500 meters, all belonging to the category of "more than one hundred feet".

From here on, Xia Rufei needed to control his speed, because the stone cave could be presented to his vision at any time. He had to check it carefully little by little to not miss the stone cave.

When he reached a depth of more than 300 meters, his mental power suppression became stronger and stronger. Basically, the range that Xia Rufei could detect was only 40 or 50 meters. It can be foreseen that the lower he went, the smaller the mental power detection range would be.

Now Xia Rufei basically relies on his mental power to investigate little by little.

I slowly got to a distance of more than 330 meters, and it was already a depth of 100 feet.

Xia Rufei first used his mental power to carefully investigate downwards and on both sides. After not finding any danger, he made up his mind and turned on the headlight directly.

Under the light, the situation deep in the crack of more than 300 meters was clearly presented in front of Xia Rufei.
