Lurking underground, Xie Aoyu's heart and ears exerted his power, eavesdropping on every voice carefully, especially paying attention to the two of them who looked similar to Ye Feilin as described.

Why, I don't know if these people are dedicated to cultivation, or if they have strict orders, they don't communicate with each other casually, and even if they speak, it is about cultivation, so that Xie Aoyu was stuffy underground for two hours, and he didn't judge which one was Ye Feilin, and when he was bored, he checked the terrain of this place while keeping his heart and ears eavesdropping.

This is the forbidden place that the King of Man left behind the soulless spirit dragon to destroy the Heavenly Silent Mountain.

The fluctuation of this mine attribute is extremely strong, so Xie Aoyu judged that the soulless spirit dragon is a thunder attribute, and Chu Tianxiang should also encounter ten thousand thunder strikes near here, so as to come into contact with the thunder and lightning mystery.

Thinking of the source of thunder and lightning, Xie Aoyu's mind couldn't help but imagine that possible scenario.

Ten thousand thunders hit the top, the thunder and lightning mystery appeared, and Chu Tianxiang got it, so the thunder and lightning essence in the ten thousand thunders that would inevitably be triggered fell into this place with Chu Tianxiang.

Thunderbolt Essence?

Xie Aoyu's heart moved, his Xuan Lei itself was already at the stage of Dacheng, and he needed to absorb a considerable amount of thunder power before he could hope to reach the Dacheng realm.

Judging by his power of Xuan Lei, although Xuan Lei is very close to Dacheng, it is not so easy to cross that threshold, even in the Star Family's Thunder Abyss, only a little thunder essence can reach Xuan Lei absorption, unless it is also Xuan Lei, but Ling Lei is difficult to find, Xuan Lei has almost heard of it.

But where the mystery of thunder and lightning is, it is naturally the most essential place of thunder and lightning.

I'm afraid this kind of essence is the essence of Xuan Lei, if it can be obtained for his Xuan Lei, Dacheng can be waited!

With this in mind in Xie Aoyu's mind, he began to sense the power of thunder and lightning around him.

According to his original induction at the location of the soulless spirit dragon outside the Tianluo Holy Land, there were many fire-related magical things born at that time, but there was no essence of fire underground, and here it was the opposite, the magical things on the surface were not seen, and they may have been taken away by the people of Tianshan Mountain, after all, those who stayed here were all masters of the thunder attribute, but in this underground, he felt a trace of thunder and lightning power fluctuations.

This fluctuation is not very strong, but as Xie Aoyu slowly dives, the induction becomes stronger and stronger.

After diving to three hundred meters, the silent Xuan Lei in Xie Aoyu's dantian suddenly jumped a few times, as if something made it sense.

Immediately, Xuan Lei became agitated.

Xie Aoyu also felt more clearly, as if there was a huge and amazing thunderbolt existing underground, and this thunder and lightning seemed to have sensed the existence of Xuan Thunder and began to **.

"Boom ......"

Before Xie Aoyu could get closer, a dark purple, almost black thunderbolt burst out from the ground, blasting towards Xie Aoyu.

The power of that thunder and lightning was so strong that Xie Aoyu was a little shocked.

It's just such an ordinary attack, and it has the level of strength equivalent to the first-order Battle Emperor.

"No wonder there is a thunder and lightning essence here, and the masters on the Heavenly Silence Mountain are also indifferent, I am afraid that the deepest core power is difficult for even a third-order battle emperor-level powerhouse to resist. Xie Aoyu waved the thunder and easily defused the thunderbolt attack, "So those people are not only protecting the forbidden land from being entered, but also guarding this thunder and lightning essence, reserved for the higher-level thunder system war emperors, hehe, since that's the case, then I'm welcome." ”

If it is the power of other departments, especially the powerful power naturally generated by heaven and earth, Xie Aoyu really can't help it, but the power of thunder and lightning is different, he has Xuan Thunder, and he himself has the ability to almost immune to the power of thunder and lightning.

Dive quickly.

Xuanlei shroud.

Xie Aoyu's sense is also getting stronger and stronger, and the thunder and lightning essence below seems to have evolved beyond the point of spiritual thunder, although there is no human mind, but like a spiritual artifact, it has a certain aggression towards the life of the outside world, as if it is born with self-protection.

The stronger the attack, the higher its level.

Xuan Lei is also obviously more restless, it has already reached the edge of Dacheng, continue to enrich itself with thunder and lightning power, there are signs of not being controlled by Xie Aoyu, taking the initiative, the location of the thunder and lightning, I am afraid that it is also Xuan Lei, the strength is only equivalent to the strength of the third and fourth order battle emperor level, but Xuan Lei is different, Xie Aoyu has always been able to exert its strength only four or fifty percent, this time it was stimulated, there is no need for Xie Aoyu to exert its power, he is ** Get up, this completely unleashes all the power, then it is not comparable to the power exerted by Xie Aoyu, after all, it is close to the Dacheng stage, and the lowest is equivalent to the power of the seventh-order Battle Emperor level.

"It would be nice if I could use this power as I please. Xie Aoyu felt Xuan Lei's amazing energy fluctuations, and he also had some thoughts.

If he could exert the full power of Xuan Lei, he would have relied on Xuan Lei to destroy the third-order War Emperor powerhouse outside, and Xie Aoyu would no longer restrain Xuan Lei and release himself to his heart's content.

Xuan Lei also seemed to have life, dragging Xie Aoyu towards the ground.

Where the underground thunder was located, there were even more intense thunder and lightning fluctuations, which faintly made Xie Aoyu sense that it was close to the power of the third-order Battle Emperor-level bloodthirsty demon rat.

"Boom, boom, boom......"

The roar continued, and everything below was revealed.

It was a black lightning bolt like ink, hovering horizontally about 900 meters underground, flashing with black light, and the dark purple thunder and lightning emitted by it.

Xuan Lei!

Xie Aoyu could conclude at a glance that this black thunder and lightning was Xuan Lei.

"According to what the ancestor said, to be able to produce thunder and lightning mysteries, it must be a manifestation of a large explosion of thunder and electricity in heaven and earth, and the thunder and lightning essence emitted from it should be the peak of spiritual thunder, and there are some Xuan Lei, but there is only such a Xuan Thunder here, and there is no large number of spiritual thunder. Xie Aoyu recalled what Shu Ancestor said, and his eyes gradually brightened, "Most of the thunder and lightning essence caused by the Thunder and Lightning Mystery should be in that forbidden land!"

With this, Xie Aoyu's mind became active.

If he could get a large amount of thunder and lightning essence, Xuan Lei Dacheng would definitely be a sure thing, but when he thought of the situation outside, he had a little headache.

Inside and outside the forbidden land, there are third-order battle emperor-level powerhouses, and there are many second-order battle emperor-level powerhouses, and it is far from easy to seize the thunder and lightning essence.

Thinking about it, Xie Aoyu still decided to take down this black Xuanlei first.

With a flick of his fingers, the Xuan Thunder that was close to Dacheng burst out.

This Xuan Thunder turned into a purple light mask, and it wanted to envelop the entire black Xuan Thunder, and its all-round attack immediately caused the ** of the black Xuan Thunder.

"Boom, boom, boom......"

The black Xuan Thunder erupted with amazing power, and that majestic power made Xie Aoyu feel the appearance of the Ice Flame Nether Leopard King being enraged, and the power exploded in full force.

Such a force immediately caused irregular fluctuations on the ground within a radius of 100 meters, and countless subtle lightning bolts shot out from the ground, and there seemed to be countless thunderbolt fish swimming on the surface.

Looking so sober, the expression of the third-order Battle Emperor-level powerhouse of Silent Mountain changed slightly, "It's not good, someone wants to seize the Xuan Thunder below!"

"Elder, activate the spell formation!" a second-order battle emperor-level powerhouse said, "That Xuanlei is about nine hundred meters underground, and those who can enter the underground in front of us, without knowing it, must have the magic of entering the ground, either Xie Aoyu, or a very powerful demonic beast, no matter which possibility, it will be good for us to capture it, and if the demonic beast is used, it can also increase the strength of my Heavenly Silent Mountain, and often the demonic beast that has the magic of entering the ground, it has very amazing potential." ”

The third-order battle emperor-level powerhouse smiled slightly, what this person said was exactly what he thought.

Either way, it has a very strong temptation for him.

A third-order battle emperor-level powerhouse should use his hands to make a little void.

"Smack!"

A beam of light shot out from the fingertips of the third-order Battle Emperor-level powerhouse, and it turned into a little halo in the air and spread in all directions, and soon saw a huge spell pattern appearing in the void, which was very illusory, as if it was formed by the accumulation of mist, and it could be dispersed at any time.

But seeing this, all the masters of Tianshan Mountain know that the following people who cause the turmoil of the black thunder are afraid that they are going to be unlucky, because this is an unpredictable spell formation inherited from ancient times in Tianshan Mountain, its power is elastic, what realm of people urge, its power is the power of that person's realm, such as this third-order war emperor-level powerhouse stimulated, the power of this spell formation is equivalent to the power of the third-order war emperor level, if it can be activated by the ninth-order war emperor level, then it is the power of the ninth-order war emperor-level spell formation.

This time it was stimulated, and the spell formation suddenly bloomed with brilliant brilliance, quickly penetrating into the ground, and extremely strong power fluctuations surged on the surface.

"Let's go!" the third-order Battle Emperor-level powerhouse snapped, and he was the first to leap into the air and land on top of the spell formation.

The other top ten Battle Emperor-level powerhouses also leapt above that spell formation.

Everyone occupies a place.

Under the leadership of the spell formation, these eleven people went underground, as if they could use thaumaturgy into the ground, which was the mystery of the spell formation.

The two people who looked similar to Ye Feilin were not among them, these two were still staying on a small hill, but they were already very vigilant.

The appearance of the spell formation immediately attracted Xie Aoyu's attention.

With his heart-to-heart communication, Xie Aoyu can hear the things on the surface of the ground nine hundred meters clearly, and with the induction of strength, he can also estimate the same.

Xie Aoyu looked at the Xuan Lei who was still shrouded, and the black Xuan Lei who resisted, a smile appeared on the corner of his mouth, this was stimulated, and the most powerful Xuan Lei burst out, and it was the strongest power that he had never inspired before.

Dive!

Without hesitation, Xie Aoyu quickly dived.

He didn't stop until he was more than a thousand meters underground, and he reached about a hundred meters below the location of the Black Xuanlei.

Although the strongest power of these two Xuan Thunder was stimulated by each other, Xie Aoyu was able to take the opportunity to barely control his own Xuan Lei line, just a line, with the power that was stimulated now, it was enough to solve everything.

He watched quietly, silently calculating.

As far as he was concerned, this was an opportunity, not only to make Xuan Lei possible, but also to take the opportunity to kill those two masters who looked like Ye Feilin.

The spell formation continued to decline.

The eleven War Emperor-level powerhouses carried above were also on guard, staring at them with fierce eyes, because it was underground, and there was a yellow patch all around, and they all pricked up their ears to listen carefully.

Soon, they had reached a place of more than eight hundred meters, and they were already close to the location of the two Xuan Thunderbolts.

The spell formation bloomed with brilliant light, causing a burst of softness to appear in the ground within a radius of 100 meters, as if it had been hollowed out by the spell formation.

At the same time, the Xuanlei Devouring that Xie Aoyu was paying attention to also appeared.

After his Xuan Lei, who was already close to Dacheng, was stimulated to burst out with all his power, he completely ignored the resistance of the Black Xuan Thunder, which was only comparable to the power of the third-order War Emperor, the gap was too big, it suddenly fell, and the black Xuan Thunder was wrapped.

The fusion of the two thunderbolts is a process of devouring.

As the master of Xuan Lei, Xie Aoyu has a very obvious feeling about its changes, the black Xuan Lei has no ability to resist at all in front of his Xuan Lei, and it is fully devoured and digested by it, and the strength of Xuan Lei has increased to a certain extent, but there is still some gap for it to reach Dacheng.

The Xuan Thunder itself is to reach the Dacheng realm, that is, the power of a strong man equivalent to the peak realm of the ninth order Battle Emperor, and it itself is only the power equivalent to the peak power of the seventh order War Emperor, after devouring the black Xuan Lei, it can already be comparable to the strength of the eighth order Battle Emperor level, but there is still a certain gap from Dacheng.

Sensing Xuan Lei's desire for thunder power, Xie Aoyu's mind also became active.

How can Xuanlei reach the realm of Dacheng?

Must be Lightning Essence!

Obviously, there should be in the forbidden land, and there are not a few, Xie Aoyu looked at the irascible Xuan Lei, it was very likely that it had sensed the thunder and lightning essence in the forbidden land, so after devouring the black Xuan Lei, there was still no appearance of constricting the power at all, Xie Aoyu saw this, and with the control of the connection of the Xuan Lei, he suddenly urged it to bombard towards the spell formation that was diving.
