"Whew-"

An arrow of thunder and fire shot into the head of the three-striped Heavenly Demon Bull.

Li Yuan did not stop attacking, his body fell quickly, put away the Xiao Thunder Bow, and took out the rusty broken knife that he had found in the battlefield of the Thousand Kings Fall before.

"This broken knife...... No...... The short knife is a spiritual treasure, let this calf test its power. ”

With a loud shout, Li Yuan poured Yuan Li into the short knife.

The thunder light suddenly lit up, and he slashed at the three-striped Heavenly Demon Cow.

The thunder fire knife flew out vigorously, like a thunder dragon.

"Click-"

The strength of the knife slashed through the neck of the three-patterned Heavenly Demon Cow, and the body separated in an instant.

When Li Yuan saw this, he was immediately shocked.

The previous attacks were too frequent, and the consumption of Yuan Force in the body was large, and it was not a full blow, but it actually cut off the neck of the Three-Pattern Heavenly Demon Cow.

This knife can completely kill the three-pattern Heavenly Demon Cow, and it is not that it is vulnerable, but the Heavenly Demon Cow that has entered the pupation stage, and its physical strength is less than half of that of usual.

"Boom-"

The huge body of the Three-Striped Heavenly Demon Cow fell to the ground, smashing countless giant trees, causing dust and mist, and grass and trees flying sideways.

Ignoring the smoke and dust from the huge body of the Yuan Bone Demon Beast smashing into the ground, Li Yuan rushed in directly.

Take away Nedan and don't want anything else, and then turn into lightning, fly out of the smoke and dust, and quickly leave the scene.

After a big battle, it will inevitably attract the strong people in the Baiyuan Forest Sea.

He had just flown out a few miles when a small black hole blocked his way.

Two blood-colored beams lit up in the black hole, which was very penetrating.

"Be careful, it's the Black Butterfly." Spirit reminded.

"Damn it!" Li Yuan exclaimed.

This place is the territory of the Heavenly Demon Cow clan, and the Black Demon Butterfly appeared at this time, afraid that it has been monitoring the Three-Pattern Heavenly Demon Cow for a long time.

The small black hole that envelops a radius of forty or fifty zhang is the body of the black magic butterfly, and two blood-colored beams of light are its eyes.

It was horizontally in front of it, black and black, surrounded by black smoke, flapping its huge wings and accelerating the spread of black smoke.

The aura is stronger than the three-pattern heavenly demon cow that Li Yuan killed just now, more than a star and a half, and half a foot has stepped into the fifth-level demon beast.

Li Yuan knew that he was not his opponent, and released his soul power to explore whether there was any possibility of escape.

"Human boy, you killed the king's prey?"

The Black Devil Butterfly spoke, obviously a woman's voice, and her questioning tone was extremely cold.

Li Yuan's back was cold.

Just out of the wolf's den, and into the tiger's den.

The Black Devil Butterfly especially likes to devour the Heavenly Demon Bull to advance to strength.

She had been monitoring the three-striped Heavenly Demon Bull for a long time, and she should have been waiting for the latter to completely pupate.

Devouring the Heavenly Demon Cow in the pupation stage, it is most effective to improve its strength.

Although it was only a three-pattern Heavenly Demon Cow, it was enough for the Black Demon Butterfly to successfully advance to the fifth-level demon beast.

Li Yuan stood on the Qiankun Ding, thought for a moment, and said, "It's just to save my life, and I hope that the Butterfly King will let me go." ”

"Let you go? You killed the king's promotion, who will pay for this loss? ”

Above the sky, the giant black devil butterfly shouted.

"This Neidan, hand it over to the Butterfly King, and I'll leave, how about it?"

Li Yuan took out a black and cyan demon beast inner pill, which was the inner pill of the three-pattern heavenly demon cow.

He didn't want to fight the other party, and he was afraid of the Black Devil Butterfly's murderous reputation.

According to the spirit, the Black Demon Butterfly has a trace of the bloodline of the ancient divine beast devouring the sky and the black abyss in its body.

Therefore, the Black Devil Butterfly is a half-blood divine beast, and it has the Black Bone of the Demon Butterfly in its body, which is an innate Xuan Bone, and it is easy to evolve into an Earth Bone.

And this bone has a certain chance of having Devouring Bone Qi, but this Black Devil Butterfly does not have it.

In the face of such a powerful opponent, Li Yuan was not tough in tone.

There is a gap in strength, and he has just experienced a big battle, which is also a factor he considers.

Hearing this, the Black Devil Butterfly let out a giggling horror laugh and said, "Let you go?" Stupid human, are you too naïve?

"Hehe, I see you're also a Thunder Element.

"It just so happens that this king has recently been in the stage of butterfly transformation, and now that three-patterned heavenly demon cow is dead, and it has little effect.

"Moreover, it is useless for this king to devour too many fourth-level demon beasts.

"It's rare to meet a human Thunder Element.

"Why don't you and the dead Three-Pattern Heavenly Demon Cow help this king successfully advance to the fifth level?"

Hearing such an impudent request from the Black Demon Butterfly, Li Yuan frowned slightly, and then shook his head and chuckled, "You are not a real fifth-level demon beast yet.

"With a trace of bloodline in the body that swallows the sky and the black abyss, I call you the Butterfly King.

"Do you really think that you are a fifth-level demon beast, and you are honored to be worshiped by all beasts?"

"Human boy, Hugh has to take advantage of the power of his tongue, and I will swallow you alive." The Black Butterfly's voice grew colder.

Sighing lightly, Li Yuan said helplessly: "I'm not your opponent, I don't want to be your enemy."

"But if I fight to the death and seriously injure you, you will definitely not be able to advance for the rest of your life."

The black devil butterfly, like a black hole, let out a cruel grin, and the earth trembled.

After a while, she slowly retracted her smile, and her voice was cold: "Don't be ashamed!" ”

After that, he flapped his wings gently, and the heavens and the earth shook.

The Black Devil Butterfly emitted a black mist in the sky, like a dark abyss, and black lightning shone around it.

"Suffer death! Mankind! ”

The majestic Yuan Force erupted, and the black thunder was terrifying.

Flapping its wings slightly, a black light flew out, like a huge divine whip, cutting through countless giant trees, which made people tremble.

"Bell—"

This whip originally wanted to directly hit Li Yuan to serious injury, but it was blocked by the short knife that suddenly appeared in Li Yuan's hand, changed direction, and slashed towards the ground.

Li Yuan was extremely uncomfortable, and was blasted out dozens of zhang, and a mouthful of red blood spurted out.

The Black Devil Butterfly exclaimed: "I said how a little human in the late stage of Nirvana, dare to be arrogant in front of this king, originally there were some hole cards."

"Your short knife is good, and the nine-colored crystal tripod under your feet is all the king's."

Ignoring the injuries on his body, looking at the short knife in his hand, Li Yuan was slightly shocked in his heart, he was worthy of being a spiritual treasure before, and he was able to block the blow of the Black Demon Butterfly.

The Black Devil Butterfly flapped its wings again, and five black lightning bolts flew out of its body, wanting to directly kill this human youth who surprised him.

Wiping the blood from the corner of his mouth, Li Yuan's eyes were cold, and he held a short knife in his hand, pouring all the Yuan Force of the four systems of Thunder Light and Wood Fire into the short knife.

The rust on the short knife began to fall off, emitting a dazzling thunderous light, and the arc jumped, slashing horizontally, and a terrifying knife power permeated, as if it had descended from the sky.

"Bang bang—"

All five black lightning bolts were cut off and submerged into the black mist.

With a shake of its wings, the Black Saucer soared into the sky.

Suddenly, a thunderous explosion sounded, and behind the huge figure, black mist suddenly gathered and began to tear through the void.

Suddenly, in the black mist, the yuan pattern emerged.

Immediately after, a red and black circular abyss appeared, from which small demon butterflies the size of half a zhang and black smoke lingered.

"Tattoo Yuan Technique, Black Devil Butterfly Heaven!" Black Butterfly shouted.

Looking at the terrifying Fluttershy who attacked, Li Yuan was shocked: "Wen Yuan Technique? ”

"Half-blood divine beast, it's not surprising that there is a tattoo element technique in the bloodline inheritance.

"However, she hasn't experienced the Heavenly Tribulation yet, and she is only a fourth-level demon beast, so she can't exert the true power of the Pattern Yuan Technique." Ling said lightly.

Li Yuan holds the knife in both hands, and without the heart to ask, he keeps slashing Fluttershy, and the slashed Fluttershy turns into black mist in an instant.

The red and black abyss behind the black magic disc, there were too many small magic butterflies flying out, Li Yuan's two fists were difficult to defeat with four hands, and he was still hit several times, and there were many scars on his body.

With a flicker of his figure, Li Yuan turned into blue silver lightning and avoided the attack of the little black butterfly.

When he reached the limit, he showed his figure, and with a wave of his palm, the thundercloud handprint flew out and blasted towards the small black butterfly that was sweeping away.

"Fifth-order Yuan Technique, this king underestimated you." The Black Demon Butterfly exclaimed, "The radius is shrouded in my black mist for several miles, and it is an endless black abyss, you can't escape."

"What about the fifth-order Yuan Technique, it's not the Wen Yuan Technique after all."

Li Yuan was not to be outdone: "You have not experienced the tribulation, the Wenyuan technique is in your hands, and its power cannot be exerted." It's just an ordinary fifth-order elemental technique. ”

Although it did not hurt the Black Devil Butterfly for half a point, and there were many injuries on his body, he had to have momentum.

There is a gap in cultivation between them, and if Li Yuan reaches the perfection of Nirvana, he will not be so embarrassed.

Constantly moving sideways in the air, leaving behind the thunder and thunder.

After dodging several attacks in succession, Li Yuan had a thought in his heart, his body rolled sideways, and four thunder blades appeared out of thin air, hitting a small black butterfly half a foot in size.

While controlling the Earth Evil Blade, Li Yuan took out the Xiao Thunder Bow and shot several arrows in succession.

"Boom-"

Thunderclouds constantly appeared, and countless thunderbolts poured out of them, attacking the small black butterflies that flew out of the red and black abyss.

With a flip of his palm, two maroon beads were clasped in his hand, injecting thunder and fire, and throwing them into the sky to control the black magic butterfly in the sky.

Suddenly, the twin beads exploded, erupting in devastating red flames that surged towards the Black Devil Butterfly.

The black devil butterfly flapped its wings lightly, and with a "buzz" sound, the black light flashed.

"Bang bang bang-"

The forces collided, and a muffled thunder broke out, spreading to a radius of hundreds of miles.

The two bursting bombs couldn't even hurt half of this half-blood divine beast.

You must know that Li Yuan is now the peak powerhouse of the late stage of Nirvana, and with the power of thunder and fire poured in, the power of the two bursting bombs can be imagined.

Li Yuan held his chest and coughed dryly, the consumption of Yuan Li was huge, and he was constantly injured, so he couldn't support it.

Although the means were exhausted, the difference in strength between the two sides was too great.

"Human boy, what other means do you have, this king will convince you and obediently help this king advance."

Above the sky, the red and black circular abyss behind the black butterfly is still flying out of the black butterfly.

"What should I do?" Li Yuan asked Ling, "I'm afraid I won't be able to get out today." ”

Ling was angry and said, "Who told you to be reckless." With the late stage of Nirvana's cultivation, you want to compete with the Black Demon Butterfly who has half a foot in the fifth level?

"Her body is an innate Xuan Bone, and although she does not possess the Devouring Bone Qi, she cannot exert her power yet.

"But it's also enough to compete with the spirit pattern that is still growing in your body.

"In front of her, your Yuan Bone advantage is gone."

Li Yuan smiled awkwardly and said, "What should I do?" ”

Linghu said suspiciously: "Are you going to try again alone?" Be careful that people don't escape, and their lives are lost here. ”

"Lives matter." Li Yuandao.

"Then you don't call those two out to help." Spiritual Path.

Hearing this, Li Yuan looked at the edge of the area shrouded in black mist, groaned slightly, and shouted: "Two, if you don't make a move, everyone won't be able to escape." ”

The Black Devil Butterfly was stunned for a moment, and then said: "I didn't expect you to have an accomplice, but this king was careless." It seems that the heavens want this king to advance. ”

"Little one, too cunning." A muffled voice came from afar.

Li Yuan slashed the little black butterfly with a knife and responded: "Wenxuan Protector, this is not the time to chat, while I still have some strength to spare, the three of us joining forces may not have no chance of winning." ”

While fighting with the Black Devil Butterfly, Li Yuan released his soul power within a radius of sixty miles, looking for an opportunity to escape.

After all, the opponent's strength is too strong, and he is just trying the gap between them.

didn't find a chance to escape, but found Gong Wenxuan and Tong Ming in Leiyin Valley.

When facing the enemy, deliberately move closer to the two.

The reason why it was possible to determine that it was them was because two years ago at the Qianxue Auction House, Li Yuan remembered the breath of the two.

Moreover, five years ago, when Xia Lin won the championship, Gong Wenxuan was also present at the Qian family's auction event.

"Little guy, I'm afraid that the three of us joining forces may not be the opponent of the Black Magic Disc." Tong Ming said.

Li Yuan, who kept killing the little black butterfly, passed on the voice and persuaded him: "Your Excellency should be the elder of Thunder Sound Valley, right...... You are shrouded in her black mist, and you can't escape. ”

The Black Devil Butterfly snorted coldly, "Human boy, I know you're discussing countermeasures with your partner.

"Humph! As long as it is not a human Yuan Shen Realm, it is impossible to be the opponent of this king.

"This place is in the heart of the Thousand Peerless Cicada Mountains, and it is impossible for the human Yuan Shen Realm to come here. Die obediently! ”

"Bang-"

Countless thunder green vines stopped the little black butterfly that attacked him, Li Yuan turned his head sideways, wrapped his voice with Yuan Force, and shouted: "Wenxuan Protector, don't be scared by him."

"This beast casts the Pattern Yuan Technique, and the Yuan Power consumption is huge.

"She hasn't stepped into the fifth level, her power is very limited, hurry up.

"This elder beside you must have stopped at the pinnacle of Nirvana for many years.

"As long as you haven't refined the demon beast Neidan before, you can take her Neidan.

"Half a foot into the fifth-level thunder half-blood divine beast Inner Dan, refining it, can increase the probability of breaking through to the Yuan God Realm."

Refining the Demon Beast Neidan, it is very difficult to break through the cross-border realm.

But what Li Yuan said was true, as long as he hadn't refined a demon beast before, refining the Thunder Half-Blood Divine Beast Inner Dan with half a foot in the fifth level now would indeed be able to increase the chances of breaking through the realm.

The Black Devil Butterfly is not only a half-blood divine beast, but also has an innate Xuan Bone.

Therefore, her Neidan is not comparable to ordinary demon beasts.

As soon as the words fell, the flute sounded, like thunder, shocking the soul.

Li Yuan's solemn expression soothed a little.

The elders of Thunder Sound Valley finally made a move, they already knew that the Black Demon Butterfly's Inner Dan had an effect, so what were they doing with so much nonsense.

It's just that he didn't expect that this middle-aged man with a tiger's back and a bear's waist made good use of the yuan weapon turned out to be a transverse flute.

"This is one of the Thunder Sound Bone's Zhen Gu Yuan Techniques, the fifth-order Yuan Technique Thunder Sound Earthquake Heaven, you are the Yuan of the Thunder Sound Valley.

"The three of them are all thunder primers, this king should have thought of it a long time ago." The Black Devil Butterfly was shocked when she heard this.

"I didn't expect that the Butterfly King, who has always been in the depths of the Thousand Peerless Cicada Mountains, has heard of the Thunder Sound Valley, and also knows the Yuan Technique in the Valley, I admire it."

Hearing the Black Demon Butterfly's words, Gong Wenxuan was awe-struck and immediately responded.

At the same time, Gong Wenxuan flipped his hands, and the lyre appeared out of thin air.

Plucking the strings, a silver thunderbolt flew out of the lyre and swept towards the Black Devil Butterfly.

"What about the Yuan of Thunder Sound Valley. The three of you are not in the Yuan Shen Realm, and you are not the opponents of this king.

"The three of them are all thunder masters, and it seems that today God really wants to help this king advance.

"After waiting for more than a hundred years, I was finally expected by this king."

The Black Devil Butterfly shook its wings lightly, resisting the silver thunderbolt.
