Lu Yun looked at the behemoth in front of him, and was shocked in his heart, although his cultivation is not low now, but it is the first time he has seen such a big demon spirit.

Thinking about it carefully, the master once mentioned the description of the three-headed spirit snake, and suddenly Lu Yun had a bad feeling in his heart.

It is said that the three-headed spirit snake is an extremely rare spiritual creature in the world, it has long been extinct, he didn't expect to see this snake here, legend has it that this snake is a different species of dragon, and its lifespan can reach thousands or even tens of thousands of years.

Its three snake heads contain three different evil properties, which can spit out fire, ice and poisonous gas, and are the rarest evil spirits in the world.

And this thing is even smarter, and its cultivation is much faster than that of ordinary alien spirits, and it belongs to the rare demon spirits and evil spirits in the world, and it is difficult for anyone to survive if they encounter it.

Lu Yun didn't expect to meet him today, and he didn't know whether to be happy or sigh.

I took a look at the cave, fortunately, the entrance of the cave is not big, and I think that the huge body of the three-headed spirit snake can't enter for the time being, so I can only enter and dodge now to see if I can avoid its attack. Thinking of this, Lu Yun's body folded in the air and flew straight into the cave.

In mid-air, the six eyes of the three-headed spirit snake flashed with cold light, and with a flick of its giant tail, it swept towards Lu Yun with all its might.

I saw a violent wind suddenly rise, holding the power of opening mountains and cracking stones, and it rolled towards Lu Yun's body with great speed.

Lu Yunren was in the air, feeling the powerful force sweeping over, he was shocked, his hands were raised back with all his strength, and he slashed his palms fiercely. I only hope that I can stop the attack of the three-headed spirit snake, and second, I want to use the power of the shock to accelerate forward and enter the cave to avoid earlier.

In the dark deep valley, there was a loud earth-shattering sound, and the surrounding boulders were flying, mixed with terrifying momentum, deeply shaking the heavens and the earth.

And Lu Yun also shot into the cave first with a step away, dodging the arrogant and peerless blow of the three-headed spirit snake. Behind him, the stone walls on both sides of the cave were hit by the huge snake tail of the three-headed spirit snake, and suddenly made a shocking sound, and the whole valley trembled, and the hard stone wall was suddenly broken through a big hole, and the strange stones flew sideways, and the momentum could be described as earth-shattering.

After shooting into the hole, Lu Yun's heart was beating wildly, and standing on the ground, he could feel the entire valley trembling.

Feeling the momentum of the three-headed spirit snake outside, Lu Yun muttered to himself: "Such a big demon spirit, I'm afraid that even if the master comes, he has to retreat, only to flee for his life, I didn't expect to be met by me, it's really lucky."

I don't know why our ancestors of the Lu family chose here, although this is a treasure land of dragon veins, but it is too remote. There are countless demon spirits, who dares to come and take that thing. If I didn't have some skills, I'd be done today. As he spoke, he carefully looked at the situation around him, and his heart was extremely vigilant. The three-headed spirit snake outside the cave came with a strange whistling sound, which was very frightening, but Lu Yun ignored it.

The cave is not small, but it is bottomless. Walking down the cave, the further down he went, the heavier the gloomy aura became, and the more uneasy Lu Yun felt in his heart, as if there was some fierce beast waiting for him below. There are many small forks around, and in each fork hole, there are countless strange spirits, with different shapes and sizes. At this time, the "Haoran Tiangang" on Lu Yun's body had been replaced by the "Soul Transformation Dafa" of the Ghost Sect, and a black aura shroud slowly enveloped Lu Yun's body, and the evil and mysterious Ghost Sect thaumaturgy exuded a ferocious aura, making all the strange spirits avoid it from afar, and they did not dare to approach his body. Because he has a devouring evil aura in his body that terrifies the hearts of these spirits.

Time passed slowly, Lu Yun walked for a while, and finally came to a big hole dozens of zhang large. It seems to be the hinterland of the cave, because there are three passages around it, in a triangular shape, leading to other places. In the middle of the big hole, there is a fist-sized pearl, which illuminates the surroundings brightly. I saw a sarcophagus in the middle, surrounded by four stone statues, all of which looked like guards with weapons in their hands, each of them waiting for battle, and their swords were all in line. Outside the four guards, eight more patterns appeared, carved on the ground, all of them were some vicious-looking demon figures, like the legendary ghosts, very terrifying.

Lu Yun looked around, carefully looked at the big hole, and soon found that there were piles of white bones on the ground, and it seemed that there were at least hundreds of corpses. This made Lu Yun extra cautious, knowing that there must be a secret hidden here, otherwise there would not be so many people running to die. Quietly walking around the sarcophagus in the middle, a trace of surprise appeared on Lu Yun's face. This place is full of aura, but there is no trace of evil aura, and the fierce aura that I felt before has no trace at this time, which is really a strange thing. And all the aura here is gathered on the sarcophagus, what is hidden in it? Incomprehensible, mysterious.

Looking carefully at the eight patterns and the four guards, Lu Yun understood that there must be some secrets and dangers hidden in it, otherwise it would not have been standing in it, and it had not been taken away for so many years. After pondering for a while, Lu Yun decided to give it a try to see how powerful this formation was, so that he could make plans again.

Lu Yun carried the Confucian "Haoran Tiangang" in his right hand, and suddenly a masculine, powerful red light appeared in Lu Yun's hand. With a wave of his right hand, Lu Yun's powerful palm power sandwiched the power of the mountain-splitting stone, instantly attacking the sarcophagus in the middle. At the same time, Lu Yun's body quickly rotated one hundred and eighty degrees, and the whole person appeared on the other side, with red light flashing around his body, firmly protecting his body.

I saw that Lu Yun's incomparably powerful and fierce palm hit the sarcophagus in an instant. But when it was still three feet away from the sarcophagus, the eight demon patterns on the ground instantly emitted dazzling light, forming an air shield that firmly protected the sarcophagus inside. At the same time, the four guards inside instantly came to life, each wielding their weapons, and instantly burst out with four-color brilliant brilliance, forming a four-color magical true qi cover, circulating endlessly, forcibly blocking Lu Yun's powerful blow.

Lu Yun's face changed, and he raised his head slightly and pondered. It seems that it is not so easy to break through these two formation enchantments. In this sarcophagus, it should be the place where the ancestors of the Lu family left their treasures, what treasures are hidden in it? Why is it so strict? Lu Yun's heart was full of curiosity. Walking around the sarcophagus, Lu Yun's five-colored brilliance flowed around him, and he used his best to exert the Demon Sect's "Desire Without a Trace" to explore the mystery of this strange array with his true qi. Lu Yun kept speeding up the frequency of true qi, first one hundred to two hundred times per breath, and then it had accelerated to one thousand and two hundred times per breath, but he still couldn't enter that magical formation, and he couldn't detect any breath of that sarcophagus at all.

Lu Yun's body erupted with brilliant brilliance, and at this time, he had already exerted ten layers of skill, and the frequency of his true qi instantly accelerated to two thousand four hundred times per breath, which was already his limit, no matter how fast it was, it would not work. If it doesn't work this time, Lu Yun has no choice. Among the five techniques he practiced, the Demon Sect's "Heart Desire Without Traces" was the fastest, and the frequency of true qi could reach the highest, so he chose to use this set of techniques to explore the magic of this formation.

I remember that the master said that when he used this set of tricks, he could reach 68,600 times per breath at the earliest, which is rare in the world. And with Lu Yun's current strength, being able to reach 2,400 times per breath is already quite remarkable. Lu Yun slowly maintained the frequency of true qi at two thousand four hundred times, and the true qi began to flow slowly, slowly passing through the gaps in the formation, and probing the mystery of the formation step by step.

Time passed slowly, Lu Yun was already sweating profusely, and his body began to show signs of weakness, which was a phenomenon of excessive consumption of true qi. Finally, after holding on for a while, Lu Yun's whole body suddenly collapsed weakly, lying on the ground gasping for breath, sweat soaking through his clothes. Looking at the magical formation slightly, Lu Yun showed a smile in his eyes, and finally found out the secret of this formation, and he could have a chance to crack it, pass through this defense, and enter it.
