Killing Lei Yan, even in the ancient times of the Common Era, is just a legend, its rarity is the second largest existence in the entire universe, and the average Shenyuan person doesn't know it at all, even if it is level ∞, Long Cangqiong is estimated that no one knows this thing except for Long Wentian, the Prophet and the Sword Wuxian. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The dragon firmament has also been seen in the Persona Heaven and Earth Wonders chapter before.

It is a kind of heaven and earth strange thing with thunder, lightning, flame, and three attributes, and its thunder, lightning and flame are not ordinary things, its thunder is the god thunder of heaven and earth, lightning is also divine electricity, and its flame is even more terrifying, its flame is the Shura Jun flame full of killing breath.

This Killing Thunder Flame can only appear in this world in the Land of Thunder full of killing breath, every time this Killing Thunder Flame appears, it is earth-shattering, making the heavens and the earth tremble, even the existence that surpasses the god level is extremely small in front of it.

However, what made Long Cangqiong couldn't understand was why this Killing Thunder Flame had condensed into such a huge thunder dragon, and there was not the slightest movement in the universe, could it be because of the relationship between the things sealed in the core of this central region?

However, what exactly is sealed in this central area, this dragon firmament is completely unknown.

Then again, this killing thunder flame does not belong to the flame or the thunder, but a combination of the two, it has both the righteous qi of heaven and earth of thunder and lightning, and the killing qi of the Shura Jun Flame, which is an extremely terrifying existence.

For this legendary killing thunder flame, Long Cangqiong only stayed on the cognition of the strange things of the world of Persona, but although he had never seen it with his own eyes, but because of the terrifying aura that made his soul tremble and the killing aura in the thunder, he still recognized it at the first sight of the thunder dragon.

"Here............ It would be possible to give birth to such a huge Killing Thunder Flame Dragon............"

At this time, even with the concentration of the dragon firmament, he couldn't help but feel that his breathing was a little rapid and difficult, and after a while, he made an unconscious low murmuring sound in his mouth, and the sound was full of shock and disbelief.

The dark blue thunder dragon was entrenched in the deepest part of the thunder sea, the dragon's eyes were closed, and the sky-blue arc above the body was constantly flickering, faintly, a killing power with righteousness was quietly spreading out, making the void space around the thunder dragon present an extreme sense of distortion.

The dense dark killing thunder surrounded the dark blue thunder dragon thousands of kilometers away, and it looked like worshipping their king, and the Shura Monarch Flame in the dragon firmament, which was huddled in the energy core, trembled even more, obviously it was afraid of the thunder dragon condensed by the killing thunder flame in front of it.

"Goo............

Looking at this scene, Long Cangqiong couldn't help but swallow a mouthful of saliva, and the subtle sound was extremely loud in this silent space.

It was only at this time that Long Cangqiong understood why Shura Junyan actually shrank in the energy core and trembled after arriving here, obviously because he was afraid of the thunder dragon in front of him, but why he was afraid, Long Cangqiong was a little unclear.

Just as the dragon firmament made a sound, the dark killing thunder that was hovering around the killing thunder flame suddenly turned around at the moment, like angry dark red dragons, rushing towards the dragon firmament.

Seeing these dark thunders rushing forward, Long Cangqiong retreated again and again, his eyes flashed rapidly, and he immediately turned around and ran, if it was just a dark thunder, he was not afraid, but he had to be afraid of the thunder dragon that seemed to wake up from his sleep at any time, and from the latter's body, he felt an extremely terrifying aura. According to his speculation, if you want to use the combat power index to calculate, this thunder dragon is probably also an existence that exceeds 100,000 points, which is an existence beyond the god level.

This level, for the current Long Cangqiong, is simply an irresistible existence, so after seeing that it was discovered, Long Cangqiong did not hesitate to turn around and run.

Thundered............

The escape of the dragon firmament seemed to have attracted the attention of those dark killing thunders, and for a time attracted more and more chasing of the dark killing thunders, and in an instant, the depths of the originally silent thunder sea suddenly boiled, and the dragon firmament broke into their holy land, which seemed to completely anger the anger of these dark killing thunders, and at the moment the overwhelming dark killing thunderstorms poured out, surging towards the dragon sky from all directions, under the impact of such a number of dark killing thunders, even if it had just absorbed a lot of dark killing thunders and improved the dragon firmament, I felt some scalp tingling, and my face was a little pale.

Seeing these dark thunderstorms coming, Long Cangqiong knew that if he didn't solve it, it would be difficult to leave, and suddenly, he stopped, and a stream of energy that blended life and destruction surged out from his body.

When the dragon firmament released energy, the waves of dark killing thunder also came instantly, but just when they were about to get close to the ten meters range of the dragon firmament, a hurricane that fused life and destruction also blew up in an instant, and they were all involved in it, and then in the center of the hurricane, a dazzling black and white light lit up, instantly decomposing these dark thunders into the purest energy and integrating into this hurricane.

"Go ............"

After easily resolving the impact of the dark thunder with Tai Chi Divine Skills, the dragon firmament still did not dare to stay, a soft energy spread out from his body, turning into a pair of emerald green wings behind his back, and immediately vibrated the wings, wanting to leave here, however, just when he wanted to flee in a hurry, the cold hair on his body suddenly stood upside down, and he hurriedly turned his head, just to see the deep thunder sea in the depths, the entrenched dark blue thunder dragon, the originally closed dragon eyes, but at this time they slowly opened, and the pupils were golden, It was actually the golden pupil in the dragon's eyes. When Long Cangqiong saw the dark blue thunder dragon's dragon eyes, he immediately gasped. And as the dark blue dragon opened its golden pupils, the sky above the thunder sea, the sky blue thunder and lightning flashed, and around the huge dragon body, lightning flashed and thundered, as if the thunder and lightning in the depths of the entire thunder sea were sucked into the huge and dazzling golden dragon pupils, which looked extremely dazzling.

"Oops, this big guy actually woke up............" Stared at by the pair of golden pupils that were so cold that they didn't have the slightest emotional fluctuations, the dragon's scalp exploded, and after a pause, the emerald green wings shook vigorously, and his body turned into an emerald green meteor, shooting out towards the depths of the thunder sea.

Thundered............

Seeing that the speed of the dragon firmament increased suddenly, the thunder dragon seemed to know the intention of the dragon firmament, and at that moment, the thunder dragon's dragon mouth opened, and a huge lightning flashing sky blue was about a hundred feet loud, and it burst out from its dragon's mouth at a speed close to the speed of light, just a flicker, it caught up with the dragon firmament.

The sudden sky-blue thunder and lightning behind him made the pupils of the dragon firmament constrict, this kind of speed made him unable to escape at all, and after knowing that there was no way to escape, the dragon firmament also turned decisively at the moment, and the majestic energy quickly seeped out on the surface of the body, condensing into a black and white two-color vortex like a black hole.

After completing this layer of defense, before the dragon sky could be relieved for a moment, the azure thunder and lightning with terrifying energy appeared in his eyes, and then slammed into the black and white whirlpools in front of him.

Bang............

The strong impact made those whirlpools suddenly crack, and the dragon firmament was also startled, and hurriedly slapped it out, and the huge energy continued to surge out, strengthening the defense of the black and white vortex, but the support of the dragon firmament was also unable to block the terrifying energy, and the black and white two-color vortex condensed by him was also shattered in an instant, turning into countless black and white two-color light and slowly dissipating, and he himself was also a mouthful of blood spurted out, his whole body was shocked, and he was suddenly shocked by the terrifying energy and flew out.

The body was knocked away, but the dragon firmament did not give up, the black and white light appeared on the surface of his body again, and the powerful attraction suddenly came out, only to see the sky-blue thunder arcs covering his body, like worms, constantly drilling into his body, at the same time, after the heavenly blue thunder arc poured into the body, a terrifying violent energy was to quickly disrupt the originally orderly energy in his body, but fortunately, Long Cangqiong had the previous experience of absorbing dark thunder, Hurriedly held his breath and condensed, channeling that energy little by little, scattered in all corners of his body.

Sneer............

The sky-blue thunder light wrapped the whole body of the dragon firmament, and in the thunder light, the sky-blue thunder arcs continued to flicker, and the dark killing thunder that was originally chasing the dragon firmament also hurriedly paused and fled far away, not daring to enter within twenty meters of the dragon firmament, as if they were afraid of being contaminated with the terrifying sky-blue thunder light.

In the thunder arc, Long Cangqiong clenched his teeth, after devouring the sky-blue thunder and lightning with Tai Chi Divine Skill, a vast and extremely destructive energy suddenly gushed out of his body, flowing wantonly in his body, Long Cangqiong did not dare to be careless, and hurriedly held his breath and condensed, firmly controlling this vast energy, urging them to take the energy core in his body as the center, constantly circulating, and where these energies passed, the small sky-blue thunder arc was constantly flickering, Let the dragon firmament have a tingling and numb feeling, even after the neutralization of the Tai Chi Divine Skill, but these huge killing thunder flame energy, still make the dragon canopy painful, but fortunately, because the dragon firmament absorbed a lot of dark thunder before, the body was also strengthened by the dark thunder, so although the pain was extremely huge, at least there was no danger to life.

The azure thunder flickered, and the dragon firmament was also desperately refining the violent energy absorbed in his body, and after about a few minutes, the cold sweat on his forehead gradually faded, and his face slowly returned to normal. Those violent energies like wild horses were gradually transformed into waves of pure energy like a tide in the refining of the Dragon Firmament, flowing in all corners of his body, and under this refining, although the energy of the Dragon Firmament did not improve then, his body was fiercely strengthened once. And in the perception of the dragon firmament, his body seemed to be slowly approaching the physique of a ∞-level Divine Yuan person. This made him a little dumbfounded, this killing Lei Yan's energy attack was just such a strong effect, and it actually raised his physique to a level close to level ∞.

The sudden unexpected joy made a touch of surprise finally appear on the handsome face of the dragon firmament, but before the joy expanded, it was awakened by a subtle "click" sound in the body, and the dragon firmament was so frightened that he hurriedly looked inside, and suddenly found that there was a slight crack in a meridian in the body, and there was a slight azure thunderbolt flickering around the crack, and then went deeper into the dragon firmament and was so frightened that even the soul almost flew.

I saw that his original emerald green energy core actually trembled slightly.

"It's such a terrifying killing thunder flame, even my Ω-level energy core has some faint signs of rupture."

Seeing this scene, cold sweat suddenly broke out on Long Cangqiong's forehead, and he quickly stopped refining this energy and forced it out of his body. When Long Cangqiong forced out that energy, he realized that if there was no neutralizing effect of Tai Chi Divine Skill as the medium of refining, even if the energy core in Long Cangqiong's body was hidden in the Shura Jun Flame, the horror would have been turned into ashes when this energy rushed to people, and there were no bones left!

Opening his eyes, a sky blue thunderbolt flashed in the depths of the dragon's eyes, looked at the energy around his body, waved his hand lightly, dispelled it, and then glanced at the thunder dragon with fear.

"Go ............"

Then he whispered without hesitation. Then the body retreated sharply, and in the violent retreat, his eyes looked at the thunder dragon in the depths of the thunder sea again, where the huge body of the thunder dragon, when the dragon's body accelerated again, suddenly exploded a huge thunder arc, the thunder arc contained a poignant and majestic dragon roar, earth-shattering in this thunder sea, and the dark thunder around it, after hearing the thunder dragon's poignant and majestic dragon roar, it was also frightened far away.

"The aura is converging, this killing thunder flame is actually gathering the spirit!"

This scene made Delong Cangqiong's originally retreating figure suddenly pause, and his eyes flickered rapidly, feeling the flow of air in this thunder sea, thoughtful. Although this killing Lei Yan was extremely terrifying, after all, it did not yet possess spiritual intelligence, that is, it could not be called a living being. And this so-called gathering of spirits is the condensation of spiritual wisdom, if the killing of Lei Yan is successful, then it will transform into an existence like the weapon spirit and the previous Shura heart, a killing Lei Yan with spiritual intelligence.

Of course, this is not what Long Cangqiong thinks at this time, what he thinks is that after this gathering of spirits, killing Lei Yan will enter an extremely weak period............

Thinking of this, even a person with such a faint and powerful concentration as the dragon firmament, his heart suddenly pounded violently.
