"Huh!"

A figure flashed quickly through the vast mountains, and in a moment it stopped in front of a low, swarthy hill.

"It looks like this is the Tianfeng Cave. Yi Tian looked at a huge hole in the belly of this small mountain and muttered to himself.

The entrance of the cave is only a few zhang size, dark and deep, the strange rocks around are craggy, like a hideous giant mouth that chooses people to eat, and next to the entrance of the cave there is a stone tablet erected, which is engraved with three big characters of "Tianfeng Cave".

After Yi Tian's cultivation in the past few days, although other injuries are no longer serious, his physical body is because he used the "Nine Profound Integration" technique during the previous battle with Ying Tianxing, and now there is a lot of damage, if it is not repaired as soon as possible, it may cause damage to the foundation of his previous cultivation, which is obviously something that Yi Tian does not want to see.

And this Tianfeng Cave is a special place in the sect, and its special feature is that there is a "Nine Evil Winds" in the depths of the cave.

This Nine Evil Gang Wind is rumored to only exist in the Nine Heavens, and each Nine Evil Gang Wind is enough to easily wipe out the powerhouses of the Xuan Qi Realm, and even the strong people of the Psychic Realm are discouraged when they see it, but the power of the Gangfeng that it exudes can help people refine their physical bodies to a certain extent, so that the physical bodies can reach an extremely strong point, which also makes many people rush to it.

However, due to the huge number of Nine Evil Winds, the movement gathers together, and they only exist in the Nine Heavens, even the existence of the Apocalypse Realm is extremely difficult to obtain, so this Nine Evil Winds is also extremely rare in the Nine Domains, and I am afraid that only a behemoth like the Wind Sect will have one.

However, there are legends about the Nine Evil Winds in the Heavenly Wind Cave, and there are also legends that the powerful people in the sect captured it from the Nine Heavens and put it into it.

And Yi Tian's purpose this time is also the power of the wind in the Heavenly Wind Tunnel, because of its use of secret techniques, the potential of the physical body quickly exploded in a very short period of time, although it gained extremely powerful power in a short period of time, but it caused the physical body to be vain and the foundation was unstable.

Therefore, this time, Yi Tian wants to use the power of the Gangfeng here to re-temper his body and solve this hidden danger.

After a while, Yi Tian walked into the cave and found that it was a huge cave, about a hundred zhang square, and on the top of the cave were many strange stalactites hanging upside down, the small ones were only the size of a few feet, and the large ones were several zhang long, densely distributed on them, as if they were in an upside-down stone forest.

And along with the whole cave is the sound of the wind that reaches the ears, sometimes like a terrible shout, sometimes like a gentle murmur, which makes people feel in a trance when they hear it.

On one side of the cave there are twelve openings of a certain size, similar to the entrance of the cave outside, but the four openings on its left side are a little special, its surface is covered with a layer of white light, like a mirror, slightly fluctuating, and the eight openings on the right side seem a little different.

On the other side of the cave is a stone platform the size of a millstone, on which sits an old man dressed in white, who is meditating and cultivating silently on it.

"Senior, the disciple is here to cultivate in the Tianfeng Cave. Yi Tian stepped forward and bowed slightly.

When the old man heard this, he slowly opened his eyes, but a trace of essence flashed in those eyes made Yi Tian feel a sense of shock.

"10,000 contribution points per day in the Heavenly Hell, 1 to 8 Caves in the Earthshatter Cave, 100 contribution points per day in the first cave, and so on, 800 contribution points per day in the 8th cave. The old man in white said lightly, and then a blue light popped out and fell into Yi Tian's hands.

It was a small blue jade talisman, and the blue light on its surface rippled slightly, like a curtain of water.

"The Nine Evil Winds contain a strong evil qi, and this jade talisman can greatly weaken the erosion of the evil qi, and it can be stimulated by injecting spiritual power into it. The old man in white said a few more words and closed his eyes again.

Yi Tian was also very helpless when he saw the old man's appearance, so naturally he didn't dare to ask more, and immediately bowed and walked to the eight cave entrances on the side.

When Yi Tian got closer, he realized that there was a number engraved on the top of these eight cave entrances, corresponding to one to eight, from which he could faintly feel that there was a strong wind whirling, but when it approached the cave entrance, it seemed to be suppressed, so that the power of the wind could not be transmitted from it.

"These eight openings seem to be strong and weak, so it's no wonder that different contribution points are charged. Yi Tian lingered at the eight cave entrances for a moment, carefully feeling the power of the wind in them, and then walked into the cave with the number "six" engraved on them.

"Whew...... Hiss ......"

As soon as Yi Tian entered the cave, he suddenly felt an extremely powerful Gangfeng force instantly sweeping through his body, and the Gangfeng power hit Yi Tian's body like a sledgehammer, even Yi Tian's body couldn't help but feel a burst of pain at this time.

And with the power of that powerful wind came a strange wind sound, like a piercing scream, which was breathtaking, and at the same time, a faint black air flow was scurrying around, almost indistinguishable with the naked eye, but with the power of Yi Tian's divine thoughts, it could be seen clearly.

The faint black air flow looked extremely weak, and it seemed to be dissipated by the wind, but Yi Tian's pupils shrank, and his heart secretly raised his vigilance.

"It seems that this is the evil qi contained in the Nine Evil Winds......" Yi Tian said darkly.

The strongest of these nine evil winds is not only the power of the gangfeng, but the strange evil qi that accompanies it, that evil qi can erode people's sanity, if a slightly weaker martial artist is eroded by it, it will be instantly destroyed by this evil qi, collapse the mind, and become a crazy demon, even the strong must be careful in the face of this evil qi, otherwise the end will not be too good.

Although the evil qi in front of him was extremely subtle, Yi Tian was still in a tight position, not daring to take risks, and immediately took out the blue jade talisman, and then injected spiritual power to stimulate it.

Seeing that a blue transparent light mask was instantly formed, enveloping Yi Tian's figure and isolating the evil qi, Yi Tian couldn't help but sigh slightly when he saw the magic of this blue jade talisman, and then continued to walk forward.

It was a deep tunnel, as long as it could be, almost wide enough for five people to live in parallel, and it became more and more open as it went, but the power of the wind and the evil qi it produced were also getting stronger and stronger.

Yi Tian has been gone for an hour, although the power of this wind is strong, but it is not difficult for him to bear, but the evil qi has changed from the previous subtle and imperceptible to the naked eye now, although Yi Tian has a jade talisman to protect himself, but he still inevitably bears some evil energy, but it is difficult to pose a threat to Yi Tian.

And when Yi Tian walked for about half an hour, the front suddenly opened up, and a small underground square that was not huge appeared in front of him.

The small square is hundreds of zhang in circumference, in which several huge stone pillars are connected to the upper and lower levels, and is surrounded by deep stone walls, and the roof of the cave is inlaid with dense moonstones, emitting a soft light, illuminating the slightly dim underground square.

On the top of the square, there are many circular stone platforms, about 100 of them, each of which is about the size of a zhang, separated by a distance of several zhang from each other.

At this moment, among the hundred stone platforms, nearly half of the stone platforms were already sitting and cultivating, and wherever the stone platforms that were already occupied by people would automatically rise a black light curtain, which looked like a black pillar of light, which was specially set up in order to allow the disciples who were cultivating in it not to be disturbed.

On the other side of the square, there are three openings similar to those seen by Yi Tianlai, leading to the depths.

Yi Tian looked at the stone platform that was still half left at this moment, hesitated for a moment and continued to walk towards the three cave entrances, although the power of the wind in this place was strong, but for Yi Tian's physical body, the effect was still not too obvious.

Yi Tian walked to the three holes and found that there were also three numbers engraved on them, and the power of the wind emitted in them was also of varying strength.

After sensing it for a while, Yi Tian chose the hole on the far left, where the power of the Gangfeng was the most violent, and it was more effective for him to temper it.

And when Yi Tian entered the cave for a moment, there was a low voice of discussion on this small square.

"He actually entered the three caves, and it was one of the most violent caves in Gangfeng!" someone was surprised.

"Seeing that this person's cultivation is only about the early stage of bone quenching, he dares to go there, it's really beyond his strength!"

"Hmph, wait and see, he will know in a moment that he is powerful, and he will have to return here obediently when the time comes!"

While everyone in the square was still talking, Yi Tian had already stepped into the depths of the cave.

The deep tunnel seemed to have no end, only Yi Tian was walking alone.

Lonely, quiet, dim, deserted......

This tunnel seems to be not only refining people's bodies, but also honing their minds, although the evil qi is blocked by the jade talisman, it is still constantly eroding Yi Tian's sanity, endless howls, and poignant sounds sounded in Yi Tian's mind, as if it turned into an invisible mouth to devour Yi Tian!

However, Yi Tian just snorted coldly, and then the young shoots of the divine thought in his mind swayed slightly, and suddenly a huge power of divine thought swept out, instantly filling the whole body, isolating the evil qi from it.

Although these evil qi were not much of a threat to Yi Tian, they were enough to make him secretly frightened.

"It's no wonder that although this Heavenly Wind Cave can refine people's physical bodies to a great extent, few disciples come, and this evil aura alone makes many disciples discouraged......

Some people who are not strong-willed may be able to withstand the power of this fierce wind, but it is difficult to endure the erosion of this boundless evil qi, after all, not everyone has that extraordinary heart.
