Xu You was startled, and without thinking, he cast a wind control technique, and flashed to the side suddenly.

A fiery sword light swept silently from where he had been standing, slashing more than a dozen condensed Yin Spirits into two in the air, and then sinking into the incomparably hard cave stone wall, leaving an unfathomable slash mark.

Xu You was suddenly shocked and angry, he was about to cover his aura just now, and his spiritual sense was restrained, so he didn't notice this sudden attack, if it weren't for his keen intuition, he would have been cut in half.

At a glance, I saw a middle-aged man with sharp eyes suddenly appear on the way.

Thunderstorm ...... Xu You's face changed greatly.

Although he returned the same way, he expected that after such a long time, Lei Fengxing should have left a long time ago, but he didn't expect to happen to bump into it, which was unlucky.

A hint of surprise also flashed in Lei Fengxing's eyes, although he didn't use all his strength just now, he expected that it would be easy to attack and kill a child of the Spirit Body Realm, but he didn't expect Xu You to be able to dodge.

"Hall Master Lei, why do you want to kill me?" Xu You took a few steps back and said loudly with a wary face.

"Kill you?" Lei Fengxing's face changed slightly, and then returned to normal, "I don't understand what you said, originally I was cut off for you, but I was entangled by the Yin Spirit and went in the wrong direction, just rushed over, I saw that you seemed to have fallen behind and lost, I just helped you kill the Yin Spirit, don't you appreciate it?"

His face was pale, and he strode towards Xu You.

"Hall Master Lei, it's just the two of us here, you don't have to act. Xu You said loudly and took a few steps back, "There is no spiritual water pool at all, everything is a trap set by you, right?"

Lei Fengxing paused, looked at Xu You, and his sharp eyes were full of murderous intent: "Do you see it? Then go and die." ”

He couldn't say anything, raised his hand and slashed at Xu You's volley.

Xu You's face changed drastically, this was the first time he had faced the attack of the Spirit Realm Cultivator, and he suddenly had a terrifying feeling like a landslide and had nowhere to escape.

However, after all, he broke through the late stage of the spirit body, and his strength increased greatly, and without thinking, he struck a flame blade of Great Perfection.

A round of fireballs like red suns shot out in an instant, colliding violently with the attack sent by Lei Fengxing.

Boom! The dark and cold cave became extremely bright, and as the blazing heat and fire flashed, the cold aura was swept away, and countless Yin Spirits were reduced to nothing before they could pounce.

"The primary inferior spiritual technique of the Great Perfection Flame?" Lei Fengxing was taken aback.

He didn't watch the Lei family's year-end assessment, so he didn't know who won the first place, and he didn't even know Xu You's name.

These are not important to him, although Xu You just dodged his sword, but Lei Fengxing was only a little surprised, in his opinion, with his mid-stage peak cultivation of spiritual realm, it was too easy to kill this young man.

However, this young man was actually able to send out the primary inferior spiritual technique of the Great Perfection Flame, and resisted his mortal blow, which immediately made Lei Fengxing pay attention to it.

The primary and inferior spiritual skills of the Great Perfection Fire are enough to have the power of three or four percent of the primary and intermediate spiritual arts, it seems that this disciple is not simple, and he must be killed as soon as possible.

Suddenly, there was a flower in front of him, and after the firelight dissipated, Xu You disappeared, how could this be possible?

This is...... Void Concealment Technique?Lei Fengxing was stunned, and immediately reacted, and couldn't help but be shocked and angry.

Without thinking, he unfolded his powerful spiritual sense, searching the large area where Xu You was just now.

Although the Void Concealment Technique is rare, it is only a basic spiritual technique after all, as long as Xu You's spiritual sense is under him, he will be discovered immediately.

However, a strange scene appeared.

His spiritual sense only swept to an empty space, and in this flash of light, Xu You had disappeared without a trace.

"It's impossible to ......," an incredible thought flashed through Lei Fengxing's mind again. His reaction was not unpleasant, and his spiritual sense was so powerful that it covered a large part of the area.

Even if Xu Zhen turned into a bolt of lightning, he could detect clues.

But the fact that he didn't even notice the slightest trace is unbelievable.

There is only one possibility, Xu You's spiritual sense is above him, so he can't detect the other party. But this may be even more incredible than Xu optimizing into lightning.

In a short period of time, this young man has surprised him several times.

Although it felt extremely ridiculous, Lei Fengxing was experienced after all, and he immediately pinched the spirit decision, and instantly turned into countless powerful sword lights from his hand, hitting them in all directions like raindrops.

This is a beginner to medium spiritual art, the sword light is like rain, and it can take a large area of attack.

Immediately, the indiscriminate attack of the sword light rained down had an effect, and I saw a flame blade suddenly appear from the northwest corner close to a hundred meters away, stopping the dozen or so sword lights that shot over.

"Where are you going?" Lei Fengxing sneered and strode after him, the rain-like sword light in his hand stabbing in the northwest direction.

Xu You secretly complained, he did use the Void Concealment Technique, and because his spiritual sense was strong, he also concealed Lei Fengxing's spiritual sense scanning. It's just that I didn't expect Lei Fengxing's reaction to be so fast, his spiritual sense was not good, and he immediately attacked indiscriminately, forcing him to show his form before he could go away.

He unleashed a flaming blade with his backhand, blocking the sword light that shot at him. At the same time, he used the Wind Resisting Technique, dodging left and right to evade the pursuit of Lei Fengxing.

Although he broke through the late stage of the spirit body, his cultivation increased greatly, and the junior inferior spirit technique had the Great Perfection Heat, Xu You was not arrogant enough to think that he could compete with the monks in the middle stage of the spirit realm.

However, as long as he can escape from the range of the attack, with the Void Concealment Technique and powerful spiritual sense, Lei Fengxing should not be able to find him.

At this time, he couldn't care about returning the same way, Xu You didn't even have time to discern the direction, like a sharp arrow, roaring towards the depths of the cave with complex terrain.

Lei Fengxing pursued hard behind, but his face became more and more ugly.

He had already exerted his sword light like rain to the strongest point, and the sword light like water even turned into tidal waves, and everywhere he passed, it was all devastated.

However, because he couldn't sense Xu You's breath, most of the sword light fell on the empty space or the stone wall of the cave, and only a very small part posed a threat to Xu You, but it was dissolved by the flame blade he sent out casually.

If it was in a plain area or an open place, Xu You would naturally not be able to escape, but in this cave with extremely complex terrain, it provided him with excellent protection.

Lei Fengxing could only judge his position by relying on Xu You's resistance, but Xu You's body method was extremely fast, and the change in direction was even more instantaneous, which gave him a big headache.

In a moment, the two fled and chased each other, running dozens of miles away in the cave.

At first, Lei Fengxing could still judge Xu You's approximate location and chased Xu You quite embarrassed, but gradually the two became deadlocked, and the distance was fixed at about fifty or sixty meters, and they could no longer get close.

Moreover, Xu You used the Void Concealment Technique, which could cover his breath, but Lei Fengxing couldn't, so a large number of Yin Spirits came to Lei Fengxing to kill, but they turned a deaf ear to Xu You, which invisibly added a lot of obstacles.

After chasing for a while, seeing that he had never been able to catch up with Xu You, Lei Fengxing finally couldn't bear it anymore.

He kept using his sword light like water, and his consumption of himself was also very great, if he didn't stop like this, I am afraid that if he didn't wait to catch up with Xu You, his spiritual power would be consumed first.

The most important thing is that Lei Fengxing has more important things to do, and he doesn't have time to hunt down a child of the Spirit Body Realm in this Yin Qi Cave, even if this child seems very strange.

Thinking of this, he stopped, looked ahead and sneered: "Count yourself lucky, but if you are forced here, even if you have the empty concealment technique, it is estimated that it will be difficult to get out, so you will be trapped here for the rest of your life." ”

He turned away, his body was extremely fast, and in an instant, he was gone.

Xu You naturally heard his voice, but he still didn't dare to stop, and ran out for several miles in one breath, and then quietly entered a small cave and stopped.

Then he held his breath and waited quietly until halfway through, when there was no sound outside, and then he breathed a sigh of relief. It seems that Lei Fengxing has indeed not caught up again, and it is safe for the time being.

But as soon as he came out of the cave, Xu You smiled bitterly.

He was lost.

When he ran away just now, he didn't choose the way to go, how could he care about leaving a spiritual imprint, and at this moment he ran to this ghost place, and when he looked around, there were caves and crypts everywhere and all kinds of intersecting forks, and he couldn't tell where the original path was.

Moreover, in the caves, on the forks, and in the crypts, there are all yin spirits, with strange shapes, all hideous and terrifying, flying around, extremely infiltrating.

Fortunately, Xu You used the Void Concealment Technique to shield his breath, and these Yin Spirits couldn't perceive him, as long as he was careful not to bump into him.

He took two steps in a daze, but he really didn't know which direction to go, so he had to stop again.

I don't know where Lei Dao Thunder has gone, it seems that he is familiar with this cave, and if he can keep up with him, he should be able to find the exit...... Xu You thought to himself.

But he also knew that this was impossible, and he couldn't help but sigh and go back to the small cave.

This cave was very small, and it could only accommodate him alone, and it turned out that there were several Yin Spirits inside, which were rolled up by the Dream Shattering Blade, and their bodies were shattered in an instant, turning into pale white pure Yin and Cold Energy.

Xu You held those few clouds of cold energy and sat down.

Anyway, I can't get out for the time being, so it's better to try if this cold energy can restrain the Five Poisons Heart Devouring Pill first.

He is now in the state of Void Concealment, his breath is restrained, and he doesn't have to worry about revealing his body when the five poisons devour his heart.

He shifted his spiritual sense to the state of inner vision, and then continued to condense, and after a while, Xu You saw the five small poisonous insects on his heart in a fan-shaped manner.

Then Xu You slapped his backhand and submerged five clouds of cold energy into his chest.

Immediately, he shuddered.

The cold energy that this Yin Spirit has transformed is really too cold, not ordinary cold.

This kind of coldness is different from the cold of the Ice Technique, the cold of the Ice Technique is a simple low temperature, and this Yin Cold Energy is in the cold, and there is also a corrosive power of the Yin attribute.

If a mortal is subjected to this cold energy, he will be seriously ill at least or die at worst.
