As the thunder dragon roared, a mouthful of intense thunder dragon breath erupted. The pen ~ fun ~ pavilion www.biquge.info like a thunderous dragon's breath, with a terrifying aura that made Xiao Yi's scalp tingle, crashed into a crimson flame barrier jointly cast by the three fire demon kings.

For a while, the green thunder and demonic flames continued to erode. And the thunder net formed by the Green Thunder Trapped Demon Array continued to shrink, making the range of action that the three Fire Demon Kings could move in smaller and smaller ways.

"Demon Flame Blazing Sky!" The three fire demon kings, led by the cultivation of the four turns of mortal spirits, and the other two also have the three turns of mortal spirits, under the joint efforts of the three demons, the crimson demon flame, the terrifying high temperature constantly distorted the space. The spread of demonic flames, and the constant compression of the thunder net.

"Cruelty to animals, go to death!" the old man in the green robe roared, and reached out with one hand, shaped like a dragon's claw, and the thunder arc was beating at his fingertips. A claw poked out, and the cyan thunder dragon soared forward, also with a claw.

"Fire Demon Claw!" The Fire Demon King led by him let out a low shout, wrapped his right hand around the Demon Flame, and slapped out a Demon Claw, fighting against the Dragon Claw of the Thunder Dragon.

Time continued to pass, and in the green thunder trapped demon array, the surging aura and monstrous demonic aura of the four powerhouses continued to collide, and after a full quarter of an hour, the terrifying offensive did not weaken.

The aura of the Mortal Spirit Realm is dozens of times more condensed than the lower three realms, and the vastness is far from being comparable to the lower three realms. According to Xiao Yi's estimate, if such a battle lasts for another hour, the aura of the four powerhouses will definitely be able to preserve more than half.

Because the aura recovery ability of any strong person in the spirit realm is far from being conceivable in the lower three realms.

However, the old man in the green robe naturally realized that this is not the way, if he wants to kill these fire demon kings, he must use a killing move!

"Azure Thunder Jue - Three Dragons Dance Thunder!" The old man in the green robe bent slightly, pushed out with his palms, and the horse stepped up, the cyan Haoran Qingxuan Thunder continued to condense, and the vast aura of the mortal spirits poured out, like a roaring river rushing to the sky, and once again turned into two fierce cyan thunder dragons.

For a moment, three cyan thunder dragons flew above the head of the blue-robed old man, roaring. Although it is not a real thunder dragon, the terrifying momentum and the ferocious coercion still make people feel suffocating and uncomfortable.

"Go!" The old man in the green robe turned pale obviously, and controlling the three dragons to fight in one breath was already his limit. This thunder dragon condensed by Haoran Qingxuan Thunder is not only extraordinary, but also has a Haoran aura, and the damage to the demonic qi has increased a lot.

The three dragons roamed away, and the three fire demon kings also showed their magical powers, the blazing demon flames continued to suppress the three-headed thunder dragons, and the green thunder trapped demon array also continued to harass the three fire demon kings.

But at this time, the corners of the old man's mouth in the green robe raised, their Qing family is famous for not only Haoran Qingxuanlei, but also the art of refining weapons, the most famous of which is the secret weapon!

"Boom!" The sound of breaking the wind sounded like a mosquito's chirping, and the three rays of light and shadow were so small that they were almost invisible, but the palpitating sharpness still made the fire demon king who turned around with mortal spirits capture.

"Be careful!" the Fire Demon King shouted at the head, and his figure flashed sideways, but the cold light still pierced his waist, and it was fleeting.

This sneak attack was almost perfect, and even the suspicion that he had been peeping was extremely frightening. The Green Thunder Trap Demon Array used to restrain them, then harassed them with three dragons, and finally used the unknown secret weapon to sneak attack. It is worthy of being a strong person in the Mortal Spirit Realm of the Nancheng Qing family, and this method can be described as wonderful!

When the Fire Demon King who was the leader turned to look, the eyes of the other two Fire Demon Kings who had turned three times were already distracted, and they continued to become hollow, and their pupils that had lost their brilliance dilated. The crimson demonic flame that burned all over his body was also extinguished in an instant. The two powerful Fire Demon Kings actually fell directly?

The pain in his waist and the cold-inducing aura continued to erode his body, which made the Fire Demon King, who had escaped death, understand how his companion had died.

"Chill-inducing needles. The Fire Demon King's eyes showed anger and fear. This cold-inducing bone piercing needle is a kind of high-grade hidden weapon created by the Qing family, a disposable, but the power is close to the emperor's product. And the attribute is cold, and it has an extremely powerful restraint effect on the fire demon.

The divine needle that is constantly tempered with deep sea immersion silver and ice spirit sea crystal, but the small silver needle contains a huge amount of cold energy, one needle is enough to extinguish a fire and freeze the surface of the lake.

"Demon Heart Demon Flame!" "The Demon Heart Demon Flame!" has been suppressing the cold-causing aura in his body that is constantly eroding with the Demon Flame, and the Fire Demon King has finally erupted. As soon as he opened his mouth and spit out, the black blood spurted out, instantly forming ice cubes, and the cold-inducing aura in his body also dissipated.

On the Fire Demon King's chest, a beating black heart slowly emerged, and with each beat, the flames on the Fire Demon King's body would increase by a point.

And the crimson demon flame is constantly becoming darker, the temperature is becoming more and more terrifying, and the momentum of the Fire Demon King is constantly skyrocketing!

The old man in the green robe frowned, the cold-inducing bone penetrating needle he prepared actually made the Fire Demon King avoid the vital point, and he is now less than half of all the aura, the opponent is injured, and his aura is a little insufficient, this victory or defeat is still a little unpredictable!

"Green dragon thunder!" The old man in the green robe once again condensed a cyan thunder dragon, and when he opened his mouth, there was another thunder dragon breath.

"Die!" The Fire Demon King's eyes turned blood-red, and the wound on his waist that had been torn open by the cold-piercing needle was also constantly devoured by the demonic flames, and he recovered. The momentum of the Fire Demon King who burned the demon heart continued to skyrocket, and in the blink of an eye, he broke through to the realm of the five turns of mortal spirits, although it was only temporary, but it was also extremely terrifying.

In order to survive, this fire demon king is also out of the hole cards, the longer this demon heart burns, the longer it will take to recover, and there is a price to lose......

The demonic heart burns for one minute, and then the demonic energy is lost for one day, and the lifespan is reduced by one year,...... This is the unique secret method of the demon clan.

With one hand poking out, the monstrous demon flame turned into a giant claw and slapped it in the air, and actually slapped the thunder dragon in half, and then exploded, turning into a thunder arc in the sky.

"Cruelty to animals, don't you want to die!" the old man in the blue robe flashed with his eyes.

"Hehe, this is life-saving, not life-saving. What, old man, are you scared?" The crazy look in the Fire Demon King's eyes made the old man in the green robe tremble.

"Die for me, old fellow!" the Fire Demon King took a deep breath, and all the monstrous demonic flames were sucked into his mouth, and then he opened his mouth, and in his mouth, a crimson bead condensed.

"Demon Heart Blazing!" The crimson bead in the Fire Demon King's mouth shot out suddenly, and then exploded, turning into a flash of crimson light.

The light was only the thickness of a finger, but it made the old man in the green robe feel mortal danger. Even if it was the fifth turn of the mortal spirit, he didn't dare to force this weird red light.

It was the crimson line of fire formed by compressing the demonic flames of the Fire Demon King's body.

Wherever the blazing light passed, the ground shattered, everything withered, and the terrifying temperature, even the thunder net formed by the green thunder trapping demon array continued to crumble. After the blazing light, everything withered!

"Ice Crystal Star Shield!" The old man in the green robe looked panicked, and when he raised his hand, an ice crystal star shield that Xiao Yi had seen appeared. Xiao Yi remembered that when he was burying Xingyuan, he obtained a Xuanpin primary ice crystal star shield in the hundred floors of the hidden weapon, and finally gave it to Luo Xue. It's just that the grade is not too strong, and according to Luo Xue, in the later battle, the ice crystal star shield was also broken.

And the ice crystal star shield sacrificed by the old man in the green robe in front of him was not at all comparable to Luo Xue's side. Not only the quality, but also the breath, this ice crystal star shield has a breath that surpasses the advanced level of the Xuanpin, but it has not yet reached the level of the emperor, and it should be regarded as a quasi-emperor product.

When the Ice Crystal Star Shield was sacrificed, the surrounding air seemed to be frozen, and the cold air waves condensed and did not disperse, circling around the Ice Crystal Star Shield.

When the blazing light shone on the ice crystal star shield, there was no terrifying sound of the sky falling apart, only quiet erosion.

The blazing light continued to erode, trying to melt through the ice crystal, and the cold-causing qi on the ice crystal star shield continued to envelop, weakening the terrifying heat of the blazing light.

For a while, the two parties were actually stuck. However, the Fire Demon King and the old man in the green robe both looked distressed. The longer the Fire Demon King maintains the burning demon heart, the longer the sequelae will be, and the shorter the lifespan will be. And the old man in the green robe felt sorry for his ice crystal star shield, the value of this shield is extremely high, and the old man in the green robe is pressing the bottom of the box. This blazing light continued to dissolve the power of the Ice Crystal Star Shield, and it wouldn't be long before this Ice Crystal Star Shield would fall to the advanced level of Xuanpin.

"Hmph, I'll spare your life today!" The Fire Demon King shook his mouth, the direction of the blazing light changed, and it directly melted through the thunder net, and as soon as the thunder net was dispersed, the Fire Demon King immediately shut up. This demon heart is the foundation of the demon race, and every second left is one second.

After the Fire Demon King shut up, the aura of his whole body began to weaken. With one footstep, the figure retreated directly and disappeared into the forest. And the old man in the green robe also hurriedly sucked back the ice crystal star shield, and then sat on the grass regardless of his image. At this moment, he is also uncomfortable, this ice crystal star shield is injured, and he is not much better.

"Hey...... Old, old. The old man in the green robe sighed, took out the elixir, swallowed it, and then got up and patted his buttocks, "This place, it is not appropriate to stay for a long time!" After speaking, he turned around and walked towards the two corpses of the Fire Demon King that had turned into ice sculptures.

After two crisp sounds, the ice on the chests of the two Fire Demon Kings broke, and there were two more crimson stones in the hands of the blue-robed old man.

After the death of the demon clan, the demon heart will solidify and become what it is now, as crystal clear as a gem. And the demonic energy contained in it is extremely pure, and it can be regarded as a superb spiritual thing. The two fire demon hearts in front of him are both valued at the primary level of the emperor!

Xiao Yi licked his lips, and his figure disappeared into the canopy in an instant. reappeared, it was already a hundred meters away, and in Xiao Yi's eyes, there was endless heat.

"Hehe, the breath of the Fire Demon King is now weak to the level of the lower three realms, I am waiting for the opportunity to move, and I will definitely have a chance to kill it! The demon clan of the Demon Domain has sent a big gift, as a person from the Human Domain, how can I not accept it?"

The breeze drifted by, and Xiao Yi's figure disappeared again, and at the same time, the breath disappeared......
