The sound waves rolled in layer after layer, and the sand wall of Li Muran's body was shattered layer by layer by the sound waves.

The attack of the sound wave is certainly sharp, but the protection of the sand wall is also comprehensive, and the two are inseparable for a while.

Up to now, the two sides are already competing for the depth of their respective mana, and whoever has a deeper mana will be able to take the lead in this fight

Although Li Muran was an early stage cultivator of the iQue, he had already cultivated the "Reverse Immortal Technique" to the third turn, and his mana was much higher than that of a monk of the same level; And although Nirvana also cultivated the Reverse Immortal Technique, he only had time to cultivate the Second Transformation of the Reverse Immortal, and when it came to the condensation of mana, Li Muran still had a slight upper hand

However, after all, Nirvana is a former master of the true body stage, and his mana control and use have reached the state of supernatural power, and every trace of mana is used just right, and there is no waste at all; So in this way, Nirvana will not be left behind at all.

However, under the great power of the quicksand sword, he also couldn't take advantage of it.

Nirvana finally slapped it with a slap, and the golden bell finally couldn't bear it anymore, and it shattered completely, but the last sound wave that came out before it shattered was also the strongest one. This sound wave was extremely fast, directly swallowing the previous sound waves, turning them into a more powerful sound wave and rushing towards Li Muran.

Trapped in this ring ruler space, Li Muran had no way to avoid it, so he could only use his quicksand sword with all his strength to protect his whole body

"Boom" In a continuous muffled sound, the sand wall was shattered invisibly by the sound wave, and even the body of the quicksand sword was completely shattered under this blow, but the power of the sound wave gradually weakened after the quicksand sword was destroyed.

The quicksand sword was destroyed, and Li Muran hurriedly sacrificed the ice attribute rune spirit with a shake of his robe, and the latter turned into a snow leopard and opened its mouth to spew out a stream of extremely cold white gas, and the white gas instantly condensed into a transparent ice wall, blocking the last residual power of the sound wave.

With a crisp bang, the ice wall collapsed, but the power of the sound wave was completely exhausted.

"Boy, it's really you" Nirvana's eyes shrank, and he sighed lightly: "I still underestimate you that in the past few years, you have not been lazy in cultivation, and you have mastered so many powerful means."

Li Muran was silent, he had consumed a lot of mana just now, and his breath was a little chaotic, he took this opportunity to adjust his breath mana while ordering the snow leopard rune spirit to continue to attack the other party.

The same is true of Nirvana, although he has a relaxed smile on his face, he is also secretly adjusting his breath.

"Huhu" Snow Leopard Fu Spirit jumped in the air, opened its mouth and spewed out countless ice picks of cold air, shooting densely towards Nirvana.

Nirvana only glanced at it, and slapped a palm with his hand, and a pure white light shone out, which was also a lost light.

Sure enough, under this lost light, the cold qi of the ice pick almost collapsed into invisibility, but there were still wisps of extremely cold qi that invaded the vicinity of Nirvana's body, making him feel cold all over his body, and he couldn't help but shiver.

"What a strong extremely cold power" Nirvana was stunned for a moment, and he realized that the cold aura contained in the other party's rune spirit was very extraordinary

"Could it be the innate extreme cold qi?" Nirvana said secretly in his heart, "If this is the case, there is still room for further improvement in the quality of this rune spirit."

However, after all, it was just a rune spirit, and with Nirvana's magical means, he was surprised, and he didn't suffer much threat if he took a little protection.

In a matter of moments, Nirvana finished adjusting, and while he sacrificed a small amount of golden flame to resist the cold aura of the snow leopard rune, he also took out a red vial.

Nirvana held the vial in one hand, showed a little hesitation on his face, and muttered: "I thought I was going to deal with you, and the previous few methods were enough to kill you ten times I didn't expect it, but I was forced to use this trick, you really shocked this seat."

With that, he frowned, a hint of determination flashed in his eyes, and then he looked up and drank something from the vial.

In an instant, the aura on Nirvana's body changed greatly, not only his eyes were bloodshot, but his exposed skin was also red and wanted to ooze blood

"What a heavy demonic aura" Li Muran was shocked, "Could it be that the treasure he swallowed just now is some kind of monster?"

Li Muran immediately sacrificed a few ice explosion talismans, and immediately turned into countless fist-sized ice crystals and struck at Nirvana, who was casting spells, and each ice crystal burst on Nirvana's body, forming a stream of extremely cold qi, and the power should not be underestimated.

Not long ago, Li Muran used these ice explosion talismans to make the Demon Cultivator Jichen, who was a late-stage iQue monk, suffer a big loss, and finally lost; And Nirvana just suddenly burst out of a blood mist containing a thick bloody aura around his body, and he actually swept away all these ice crystals and the cold qi that burst out, which could not hurt Nirvana at all.

And in this blood mist, Nirvana's body shape is also undergoing drastic changes.

His whole body was as red as blood, and his body gradually rose out of thin air, becoming thin and long, as high as a zhang, and at the same time, a thin layer of skin appeared on his outstretched arms, which had been connected to his body, like a pair of fleshy wings; The corners of his mouth also became sharp and sharp, and he looked particularly hideous.

At first glance, Nirvana looks like a blood-colored bat with a red body, but it is in the state of half human and half bat

"Demon Transformation Technique" Li Muran's heart moved, he had long heard that in the Hundred Kingdoms Immortal Cultivation Realm in the Western Regions, there was a cultivation sect called Demon Spirit Gate, and their cultivation methods were very peculiar, and they could even use some treasures extracted from demon beasts to help them transform into half-human and half-demon shapes, greatly improving their mana At the same time, they often have all kinds of unbelievable magical powers.

The higher the quality of the demon beast extract used, the stronger the supernatural power obtained when turning into a demon, and now the breath of Nirvana seems to be much stronger all of a sudden, and it is obvious that the treasure in the small bottle he took just now is also of extremely high quality.

Nirvana flapped his wings and flew into the air, his wings flapped slightly, and countless wind blades struck him, and Li Muran hurriedly ordered the snow leopard rune spirit to spray out a wall of ice, finally blocking these extremely sharp wind blades.

"Hehe, today, what other means do you have to take over the supernatural powers after turning into a demon" Nirvana, who turned into a blood bat, said with a cruel smile, and his voice became sharp and harsh, sounding particularly eerie and terrifying.

"So far, there is only one way to take a risk" Li Muran didn't have time to think about it, and immediately slapped his waist to forcibly wake up the sleeping Xiaobai.

The little silver light flew out of the jade Linglong in a flash, but the sleepy eyes were apprehensive and the breath was weak, at this time, it obviously could not help Li Muran deal with a strong enemy like Nirvana

"I want to use the spirit possession technique, you don't have to do anything, and you don't have any resistance" Li Muran secretly said in his heart, he and Xiao Bai already had a heart-to-heart connection, Xiao Bai immediately understood, and stood in front of Li Muran obediently.

Li Muran stretched out a palm and pressed it on Xiaobai's head, while chanting a spell with words in his mouth; A moment later, a stream of blood light came out of his palm, and under the shroud of blood light, Xiao Bai's body gradually shrank, as if the essence of his whole body was drawn by Li Muran, and in the end, Xiao Bai became almost the size of a foot, and then Li Muran took it back into the jade Linglong.

At the same time, Li Muran's body was also undergoing drastic changes, he roared angrily, and there was a wolf-like roar, his body suddenly increased several times, he bent over, landed with both palms, and silver hair appeared all of a sudden, as if he turned into a wolf the size of several zhang, half human and half wolf

At the same time that Li Muran turned into a wolf, the half-human, half-bat Nirsheng looked at this scene in surprise, but he didn't forget to attack, but the snow leopard rune spirit tried his best to finally block his round of wind blade attacks, covering Li Muran's Shun Lì to perform the spirit possession technique.

However, at this time, the vitality contained in the snow leopard rune spirit was also exhausted, and it returned into the original form of the jade rune and was put away by Li Muran. It must be replenished with a large number of Vitality Talismans in order to continue using it.

"Hmph, this seat turns into a demon, and you have the means to possess you, but it is no less than this seat" Nirvana said coldly: "However, with the help of demon beasts, I am afraid that your Howling Moon Wolf is far inferior to the flying blood bat of this seat"

As he spoke, Nirvana opened his mouth and laughed wildly, accompanied by a sharp and piercing laughter, and an invisible sound wave hit Li Muran like a needle prick, Li Muran only felt a pain in his brain in an instant, and he sacrificed his divine thoughts outside his body, and was immediately defeated by this invisible sound.

Li Muran frowned, roared angrily, and in the thunderclap, a thunderbolt with a thickness of a foot flew out from the sudden extra lightning scorch marks between his eyebrows, penetrating the invisible sound wave, and hitting Nirvana.

Nirvana was taken aback, but he also knew that Li Muran's spirit beast had thunder and lightning supernatural powers, and after casting the spiritual possession technique, this supernatural power could naturally be temporarily driven by Li Muran.

Nirvana didn't dare to be careless, a pair of flesh wings rolled up, protecting in front of him, and a thick layer of blood mist appeared on the meat wings, blocking the thunder and lightning blow.

The arc "boomed" on the blood mist, instantly crushing these blood mist, and the aftermath of the thunder and lightning hit Nirvana's flesh wings, immediately leaving a scorched black scar.

However, as another mist of blood rose, the scars quickly disappeared.

"Hmph" Nirvana put down his wings and said with a sneer: "If you still use this trick, you won't be able to hurt this seat."

Li Muran jumped and pounced on Nirvana, but as soon as Nirvana's wings were spread, the dexterous ones dodged, and after both of them turned into half-demon shapes, their mobility and physical strength were significantly improved.

"It's a pity that it's not at night. Li Muran was unlucky in his heart, if it was on the night of the full moon, after the rune spirit, he could cast Xiaobai's moonlight technique and other more means, and at the same time, he could also cast many magical powers of the dark night technique, and the degree of movement of his body was even faster, and it was even possible to seize the opportunity to kill Nirvana

"Let you taste the blood-devouring demon flame of this seat" After Nirsheng dodged Li Muran's pounce, he laughed fiercely, and under the continuous slapping of his wings, pieces of blood-colored mist rose out, turning into a red flame and spreading out in all directions
