Chapter 1275 Thunder Source [I]

Lying underground, Xie Aoyu's heart-ear communication was effective, and he carefully eavesdropped on every sound, especially paying attention to the two people whose appearances were similar to the description of Ye Feilin.

However, it was unknown whether these people were devoted to cultivation or had strict orders, but they did not communicate with each other casually, and even if they talked, they were about cultivation. Xie Aoyu was stuck underground for two hours, but he could not determine which one was Ye Feilin. Out of boredom, he kept eavesdropping with his heart-ear communication while checking the terrain of this place.

This was the forbidden area where the Human King left the soulless dragon to destroy Tianji Mountain.

The thunder attribute fluctuations in this place were extremely strong, so Xie Aoyu judged that the soulless dragon was of thunder attribute, and Chu Tianxiang should also encounter the thunderbolt near here, and thus come into contact with the thunderbolt mystery.

Thinking of the source of thunderbolt, Xie Aoyu couldn't help but imagine that possible scenario in his mind.

The thunderbolt mystery appeared when the thunderbolt was struck, and Chu Tianxiang got it, so the thunderbolt essence in the thunderbolt that must have been triggered would fall into this place with Chu Tianxiang.

Lightning essence?

Xie Ao Yu's heart moved. His Xuan Lei itself was already at the stage of great success. He needed to absorb a considerable amount of thunder power before he could hope to reach the great success state.

Judging from his power of Xuan Lei, although Xuan Lei was very close to great success, it was not so easy to cross that threshold. Even in the Xing family's Luo Lei Yuan, there was only a little lightning essence that could be absorbed by Xuan Lei. Unless it was also Xuan Lei, Ling Lei was difficult to find. Xuan Lei was almost never heard of.

But the place where the mystery of lightning was, that was naturally the place with the most essence of lightning.

This essence was probably the essence of Xuan Lei. If his Xuan Lei could obtain it, great success was within reach!

With this in mind, Xie Ao Yu began to sense the lightning power around him.

According to his induction at the location of the soulless dragon outside the Tianluo Holy Land, many magical things related to fire were born at that time, but there was no essence of fire underground. However, it was the opposite here. The magical things on the surface were not seen. They might have been taken away by the people of Tianji Mountain. After all, those who stayed here were masters of thunder attributes. But underground, he felt a slight fluctuation of thunder and lightning power.

This fluctuation was not very strong, but as Xie Aoyu slowly dived, the induction became stronger and stronger.

After diving to 300 meters, the silent black thunder in Xie Aoyu's dantian suddenly jumped a few times, as if something made it produce induction.

Then the black thunder became agitated.

Xie Aoyu also felt more clearly that there seemed to be a huge and amazing thunder and lightning in the underground. This thunder and lightning seemed to have sensed the existence of the black thunder and began to stir.

"Boom..."

Before Xie Aoyu approached, a deep purple, almost black thunder and lightning burst out from the ground and blasted towards Xie Aoyu.

The power of the lightning was so strong that Xie Ao Yu was a little shocked.

Just such an ordinary attack, it was equivalent to the power of the first-level War Emperor.

"No wonder there is the essence of lightning here, and the masters on Tianji Mountain are indifferent. I'm afraid it's the core power in the deepest part, even the third-level War Emperor can't resist it." Xie Ao Yu waved the black thunder and easily dissolved the lightning attack, "So those people are not only protecting the forbidden area from being entered, but also guarding the essence of lightning, which is reserved for higher-level Thunder War Emperors. Hehe, in this case, I won't be polite."

If it were the power of other systems, especially the powerful power generated by the heaven and earth, Xie Ao Yu really couldn't do anything, but the power of lightning was different. He had the black thunder, which was almost immune to the power of lightning.

Dive quickly.

Covered by the black thunder.

Xie Ao Yu's induction was getting stronger and stronger. The essence of lightning below seemed to have evolved beyond the spiritual thunder. Although it did not have human thoughts, it was like a spiritual god. It had a certain degree of aggression towards the life outside, as if it was born to protect itself.

The stronger the attack power, the higher its level.

The black thunder was also obviously more agitated. It was already on the edge of great success. It continued to use the power of lightning to enrich itself. It was not under Xie Ao Yu's control and showed signs of taking the initiative to attack. The location of the lightning was probably also black thunder. Its strength was only equivalent to the strength of the third or fourth level war emperor. But black thunder was different. Xie Ao Yu had always been able to exert only 40% to 50% of its strength. This time, it was stimulated and did not need Xie Ao Yu to exert its strength. It was activated by itself. This completely released all its strength. It was not comparable to the power exerted by Xie Ao Yu. After all, it was close to the great success stage, and at least it was equivalent to the power of the seventh level war emperor.

"It would be great if I could exert this power at will." Xie Ao Yu felt the amazing energy fluctuations of black thunder and had some ideas.

If he could exert the full power of Xuan Lei, he would have relied on Xuan Lei to kill the third-level War Emperor outside. Xie Ao Yu no longer restrained Xuan Lei and released himself to his heart's content.

Xuan Lei also seemed to have a life, pulling Xie Ao Yu to rush underground.

The underground Xuan Lei was emitting stronger lightning waves, which made Xie Ao Yu feel that it was close to the power of the third-level War Emperor bloodthirsty demon rat.

"Boom boom boom..."

The roar continued, and everything below was revealed.

It was a black lightning like ink, coiling about 900 meters underground, flashing black light, and the deep purple lightning was emitted by it.

Xuan Lei!

Xie Ao Yu could tell at a glance that this black lightning was Xuan Lei.

"According to what the Tree Ancestor said, the ability to produce the secret of lightning must be a manifestation of a huge explosion of the power of thunder and electricity in the world. The lightning essence emitted from it should all be at the peak of spiritual thunder, and there are also some Xuan Lei. But here there is only one Xuan Lei, and there is no large amount of spiritual thunder." Xie Ao Yu recalled what the Tree Ancestor said, and his eyes gradually brightened, "The lightning essence caused by the secret of lightning should be mostly in the forbidden area!"

Thinking of this, Xie Ao Yu's mind became active.

If a large amount of lightning essence can be obtained, Xuan Lei Dacheng will be a sure thing, but when he thought of the situation outside, he had a headache.

There are third-level war emperors inside and outside the forbidden area, and there are many second-level war emperors. It is far from easy to seize the lightning essence.

Although he thought about it, Xie Ao Yu decided to take down this black Xuan Lei first.

He flicked his finger, and the Xuan Lei that was close to Dacheng burst out.

This mysterious thunder turned into a purple light shield, covering the entire black mysterious thunder. Its full-scale attack immediately caused the explosion of the black mysterious thunder.

"Boom boom boom..."

The black mysterious thunder burst out with amazing power. The powerful power made Xie Aoyu feel that the Ice Flame Netherworld Leopard King was angry and the power was fully exploded.

Such power immediately caused irregular fluctuations on the ground within a radius of 100 meters, and countless fine lightning bolts shot out from the ground, and it seemed that there were countless lightning fish swimming on the surface.

Seeing such a clear mind, the expression of the third-level War Emperor of Tianji Mountain changed slightly, "Not good, someone wants to seize the black thunder below!"

"Elder, activate the spell formation!" A second-level War Emperor said, "The black thunder is about 900 meters underground. The one who can enter the underground without anyone noticing in front of us must have the magic of entering the ground. It is either Xie Aoyu or a very powerful magic beast. No matter which possibility it is, it will be good for us to capture it. If it is a magic beast, it can also increase the power of Tianji Mountain, and magic beasts that have the magic of entering the ground often have very amazing potential."

The third-level War Emperor smiled slightly. What this person said was exactly what he thought.

No matter which possibility it was, it was very tempting to him.

The third-level War Emperor immediately pointed his hand at the void.

"Pah!"

A beam of light shot out from the fingertips of the third-level War Emperor-level strongman, and turned into a halo in the air and spread out in all directions. Soon, a huge spell pattern appeared in the void. It was very illusory, as if it was made of accumulated fog and could dissipate at any time.

But seeing this, all the masters of Tianji Mountain knew that those who caused the turbulence of the black thunder below were in trouble, because this was a mysterious spell formation inherited from Tianji Mountain since ancient times. Its power was elastic. The power of the person in what realm was triggered was the power of that person's realm. For example, the power of this spell formation triggered by the third-level War Emperor-level strongman was equivalent to the power of the third-level War Emperor. If it could be triggered by the ninth-level War Emperor, then it would be the power of the spell formation of the ninth-level War Emperor.

This time, the spell formation suddenly bloomed with brilliant brilliance, quickly penetrated into the ground, and the surface was surging with extremely powerful power fluctuations.

"Go!" The third-level War Emperor-level warrior shouted, and he was the first to leap into the air and land on the spell formation.

The other ten War Emperor-level warriors also leaped on the spell formation.

Each person occupied a position.

Under the guidance of the spell formation, these eleven people sank into the ground, just like using the magic of entering the ground. This is the mystery of the spell formation.

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

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

With the telepathy, Xie Aoyu heard clearly what was happening on the surface nine hundred meters above, and with the induction of power, he could also estimate it roughly.

Xie Aoyu looked at the black thunder that was still covering him, and the black thunder that resisted, and a smile appeared on the corner of his mouth. This was the black thunder that was stimulated and burst out with the strongest power. It was the strongest power he had never stimulated before.

Dive!

Without hesitation, Xie Ao Yu dived quickly.

He didn't stop until he reached more than a thousand meters underground, about a hundred meters below the location of the black thunder.

Although the strongest power of the two thunders was stimulated by each other, Xie Ao Yu was able to take the opportunity to barely control his own line of thunder. It was just a line, and judging from the power that was stimulated now, it was enough to solve everything.

He watched quietly and calculated silently.

For him, this was an opportunity, not only to make the thunder possible, but also to take the opportunity to kill the two masters who looked like Ye Feilin.

The spell formation continued to descend.

The eleven war emperor-level strongmen on it were also on guard, staring at it with a covetous look. Because it was underground, it was surrounded by a yellow haze, and they all pricked up their ears and listened carefully.

Soon, they reached more than 800 meters and were close to the location of the two thunders.

The spell formation emitted a brilliant light, causing the ground within a hundred meters in radius to become soft, as if it had been hollowed out by the spell formation.

At the same time, the Xuan Lei Devouring that Xie Ao Yu was concerned about also appeared.

After his Xuan Lei, which was close to the Great Perfection, was stimulated to burst out with all its power, it completely ignored the resistance of the black Xuan Lei, which was only comparable to the power of the third-level War Emperor. The gap was too big, and it suddenly dropped and wrapped up the black Xuan Lei.

The fusion of the two Xuan Lei was a process of devouring.

As the master of Xuan Lei, Xie Ao Yu had a very obvious feeling of its changes. In front of his Xuan Lei, the black Xuan Lei had no ability to resist at all. It was completely devoured and digested by it. The power of Xuan Lei increased to a certain extent, but it still had some gaps to reach the Great Perfection.

Xuan Lei itself had reached the Great Perfection realm, which was equivalent to the power of a strong man at the peak of the ninth-level War Emperor, and it itself was only equivalent to the power of a strong man at the peak of the seventh-level War Emperor. After devouring the black Xuan Lei, it was already comparable to the power of the eighth-level War Emperor, but it still had a certain gap from the Great Perfection.

Sensing Xuan Lei's desire for thunder and lightning power, Xie Ao Yu's mind became active.

How can Xuan Lei reach the Great Perfection realm?

It must have the essence of thunder and lightning!

Where is it? Obviously, there should be some in the forbidden area, and there are quite a few. Xie Ao Yu looked at the violent black thunder. It was very likely that it sensed the essence of lightning in the forbidden area, so after swallowing the black thunder, it still did not seem to restrain its power at all. Seeing this, Xie Ao Yu relied on his control over the connection with the black thunder and suddenly urged it to bombard the spell formation that was diving.
