The reason why Patriarch Chihuo did this was that he longed to obtain Li Yan's martial arts and the ancient treasure handkerchief.
Now he no longer cares about the other magic weapons on Li Yan.
Moreover, according to the previous experiences of cultivators entering the "Flying Sand Ancient Cave", even if someone can occasionally break some of the restrictions inside and enter the Black Hole Ancient Cave, except for Nascent Soul cultivators, there are usually only two results.
One result is that this monk will never appear in this world again; another result is that this monk will escape soon.
According to some Jindan cultivators who came out, if they did not have the strength of Yuanying realm, they would not be able to stay in there at all and would probably die soon.
Therefore, the Red Fire Ancestor judged that Li Yan would not stay in there for long and would escape on his own.
All he had to do was to continuously scan the "Flying Sand Ancient Cave" with his spiritual sense. At most, he would lose a wisp of spiritual sense when the strong wind was generated, causing secondary injuries to worsen.
As for whether Li Yan could get out of the black hole ancient cave, he had no doubt at all. As long as he could enter, he could break the ban and get out again, especially since Li Yan had the magical handkerchief ancient treasure.
Another reason why the Red Fire Ancestor chose to stay even though he knew that his cultivation level might decline was his overwhelming hatred for Li Yan.
This hatred has reached an unprecedented point. No matter what, he has to hold on for a few days. If he cannot capture Li Yan, he must make sure that Li Yan has died in there.
He believed that with Li Yan's cultivation level, he would come out in less than half an hour. He would try his best and wait for the result.
There are only five "Fire Bath Pills" refined by the Red Fire Ancestor, which can probably last for about three days. No matter what the result is, he must leave.
Otherwise, it might not be a matter of falling in realm. Without the elixir, he might even die.
Thinking of Li Yan's handkerchief, the meditating Old Fire Patriarch couldn't help but stick out his tongue and lick his cracked lips. It wasn't inevitable that his cultivation would fall, but opportunities were fleeting, so it was certainly worth it to fight for it at a price...
Li Yan's eyes went dark, and then he felt a scorching wind blowing towards him. Li Yan's spiritual shield had already been opened, and several "Ghost Car Talismans" were also attached to the spiritual shield.
Li Yan's spiritual sense had already scanned the surroundings. After feeling that everything was fine, he closed his eyes. After feeling that he might have adapted to the light in the cave, he opened his eyes again.
What came into view was a relatively wide cave with a faint yellow light flickering on the sand and stone walls.
In fact, all of this had already entered Li Yan's consciousness the moment he entered the cave, but when he looked at it with his eyes now, the perception was different.
Li Yan stood at the entrance of the black hole. He did not walk around casually because he had also seen the introduction of the "Feisha Ancient Cave" in ancient books.
After entering the ancient cave, do not walk around casually. Be careful about everything and observe carefully before deciding what to do next.
As for what kind of situations one will encounter inside, there are many different opinions in the classics. Most cultivators encounter different situations after entering the ancient cave.
The entrance to the cave behind Li Yan was sealed by a layer of translucent yellow light.
He first looked back and could roughly see the situation outside the cave through the translucent yellow light.
At this time, the figure of the Red Fire Ancestor could no longer be seen, and Li Yan's spiritual sense could not sense anything outside the cave. It seemed that everything outside the cave was just a layer of yellow, silent isolation space in his eyes.
While Li Yan was alert to his surroundings, he quickly raised his hand and shot a stream of spiritual power at the translucent yellow light at the entrance of the cave.
He soon breathed a sigh of relief, because the spiritual power could not penetrate out of the cave and was directly bounced back. It seemed that the restriction at the entrance of the cave was a two-way restriction. Whether entering or leaving, the restriction had to be broken.
Until this moment, Li Yan's heart finally relaxed a little. At least for the time being, he didn't have to worry about the Red Fire Ancestor and could easily enter here.
Li Yan thought about it again and guessed why the Red Fire Ancestor left. It might be because he was unable to enter the black hole cave for the time being, and was worried that the strong wind would appear at any time!
At this moment, he suddenly remembered the scream of the Red Fire Ancestor before.
"Ancient treasure? What is this? Could it be that the Heaven-stealing Handkerchief that Old Ancestor Chihuo mentioned just now is an ancient treasure?"
This was the first time Li Yan heard of this word, and he didn't know what it meant. But it sounded like a synonym for a very ancient magic weapon, but now was not the time for him to think about it carefully.
Having temporarily gotten rid of the pursuit from behind, Li Yan focused all his energy inside the cave.
Standing at the entrance of the cave, there were dozens of steps extending into the interior under his feet. The whole cave was generally dark in color. Even without using his spiritual sense, he could see the situation inside the cave clearly with the help of the faint yellow light flickering on the cave wall.
In Li Yan's eyes, the cave looked like an ancient cave. There was a layer of flickering yellow light on the sand and stone walls, perhaps due to earth-related magic or some other secret, making the entire ancient cave look a little mysterious.
The secret cave in the ancient cave is about twenty meters in size, which is much larger than it looks from the outside.
Li Yan remembered that the entrance to the ancient black hole cave he chose had four or five black holes of different sizes on both sides, and the distance between them was less than ten or two meters.
This made Li Yan initially think that each black hole was an entrance. After choosing any one to enter, they would eventually intersect and enter the same large ancient secret cave. Obviously, he guessed wrong.
The secret cave in the ancient cave was empty, with only one exit, and there was nothing eye-catching inside.
This surprised Li Yan very much. He used his spiritual sense to clearly scan the twenty-zhang ancient cave. No matter how he looked at it, this place was not the legendary place for adventure and treasure hunting.
"Could it be that the place I entered was originally empty, or that there were treasures that were taken away by the treasure-hunting monks in the past? In that case, the mechanical restrictions here have long been broken, and it is safe."
Li Yan stood on the steps, still not walking around casually, but kept looking around the ancient cave, thinking rapidly in his mind.
After just thinking about it, Li Yan denied his idea.
"It shouldn't be the case at all. If that's the case, then future cultivators won't have to be afraid of the strong winds outside as long as they can enter an ancient secret cave that has been explored.
After the strong wind has dissipated, you can continue to search for treasures in the nearby ancient caves and secret caves. You don't have to worry about going too deep and not having enough time to return to a safe place, thus having your flesh and blood melted by the strong wind.
Although there is no regular pattern in the generation of Gangfeng, it is recorded in historical records that there is at least a quarter of an hour between two occurrences. After a quarter of an hour, the Gangfeng may come at any time and there is no regular pattern at all.
In this way, as long as you know the time when the last strong wind extinguished, you will be worry-free for at least half a quarter of an hour. When the next ancient cave secret cave has not been broken, and you feel that the time is almost half a quarter of an hour, you only need to return to the ancient cave secret cave that has been broken before, and this fatal problem will be solved.
In this way, we can conquer one place at a time and go deeper slowly. The treasures here are easily obtainable. How can it be said to be a dangerous place? Even Yuanying cultivators regard it as a forbidden area. "
Thinking of this, Li Yan became even more cautious.
His eyes suddenly focused because he discovered a problem.
When he was outside the cave before, the yellow sand all over the ground, due to the terrain, formed quicksand groups of varying sizes and flowed into different ancient black caves.
At that time, and precisely because of this extremely confusing phenomenon, he thought that the entrance to the cave was unobstructed, and he bumped into the invisible membrane at the entrance.
Now when Li Yan looked down, he saw that there was indeed a lot of quicksand slowly flowing into the cave from the entrance on the steps where he was standing, and then forming tiny, hourglass-like lines, flowing along the steps into the cave.
What made Li Yan feel that this place was weird was that after passing through more than a dozen steps, these fine sand flows to the bottom of the secret cave in the ancient cave, and then disappears as if melted.
This phenomenon is actually very easy to spot, as there is a faint yellow light flickering on the walls of the cave, and even the top and ground of the cave are yellow.
It is easy to confuse one's senses, and what makes Li Yan feel even more weird is that in his consciousness, the ground below has always been a hard rock with a faint yellow glow.
Once those fine sands flowed in, they were like mud entering the sea, melted away, and no trace of them remained.
After seeing this scene, Li Yan felt uneasy.
Although these fine sands look like just seven or eight very fine streams of quicksand flowing down the steps, they are nothing.
But think about the long years it took for this place to be formed. No matter how big or deep the ancient cave was, it should have been filled with yellow sand long ago, let alone this ancient cave of only twenty meters in size.
To take a step back, even if the ancient cave in front of Li Yan was tens of millions of feet in size a long time ago, it was only about twenty feet large after being filled with quicksand.
However, after Li Yan's spiritual sense locked onto the ground below for a while, his expression became more and more solemn.
Even after a long time, the dozen or so steps under his feet still existed, with no signs of being buried.
At least after Li Yan's spiritual sense locked onto a tiny crack on the ground on the last step as a reference, half an hour had passed and the ground at the bottom of the cave showed no sign of rising at all.
Li Yan stood at the highest point of the steps at the cave entrance for an entire hour, with no intention of moving.
This place seems ordinary, but all the inexplicable weirdness makes Li Yan feel uneasy.
He felt as if he might be attacked suddenly from all sides at any time, and he had no intention of moving his body until he came up with his next plan.
During this hour, Li Yan's eyes occasionally swept across the cave entrance.
Through the translucent yellow light, he saw at least four times that strong winds blew outside the cave, making it impossible to see anything.
As far as the eye can see, all you can see is a gray haze at the entrance of the cave. The scene makes one imagine that a devastating sandstorm is raging.
As for the situation in the cave, so much time had passed and Li Yan had no idea.
After Li Yan thought about it, he decided to sit cross-legged at the entrance of the cave and meditate to recover first.
The earth-type spiritual energy in the ancient cave is very strong, even stronger than the spiritual energy in some first-rate sects.
Li Yan discovered this phenomenon as soon as he approached the "Feisha Ancient Cave".
The earth-type spiritual energy outside the "Feisha Ancient Cave" is only slightly higher than the surrounding area, and it cannot be said to be very good.
Only after entering the "Feisha Ancient Cave" can one feel the powerful earth spiritual energy inside, but no one dares to practice in the "Feisha Ancient Cave".
If you are not careful and strong winds arise, that is not cultivation, it is seeking death.
Only Nascent Soul cultivators can use this place to cultivate earth spiritual power, but the earth spiritual energy here is not better than the spiritual energy in the caves of those Nascent Soul old monsters. It can only be said to be upper-middle grade.
What's more, it's only earth-type spiritual energy. Nascent Soul monsters with other attributes as main spiritual roots will definitely not come here.
Li Yanxing wanted to meditate and practice here. He originally wanted to find a safe place to refine the poisonous spiritual energy that was absorbed into his body.
He stood here for an hour, but nothing unusual happened.
There was no attack for an hour, and Li Yan began to feel relieved. He had consumed a lot of mana this time, so it would be better to recover first.
There are still unknown dangers here. He has to set up a defensive warning formation first, and then observe for a while. If there is no problem, he can start practicing.
Perhaps after refining the poisonous spiritual energy this time, I can reach the middle stage of foundation building.
But just as Li Yan moved slightly, took half a step to the right, and was about to take out the formation flag, something strange happened.
Everything happened too suddenly. Although Li Yan had been vigilant, he was still caught off guard.
Because the change came from the ground under the stairs, which had been normal for an hour, and his attention was focused on the ground under the stairs.
He just felt his feet go empty, and his whole body fell rapidly downwards!
