Li Muran immediately manipulated the greedy sword with the blood of the demon dragon and fled towards the Demon Valley.

The purple python transformed by the greedy sword, with the demon dragon blood ball in its mouth, flashed several teleportations in mid-air, and soon appeared at the mouth of the valley.

At this moment, a cold flame suddenly poured out in front of him, turning the small valley mouth into a thick layer of frost.

The frost spread extremely quickly, and almost instantly sealed Taniguchi, even the power of space was sealed and isolated.

However, the greedy sword also changed very quickly, it directly pierced the void, and before the valley mouth was completely closed, it pierced out of the void outside the valley mouth, and escaped out of the valley mouth in a thrilling way.

A huge gray-white figure flashed, and the frost dragon appeared near Taniguchi, and it felt the breath of the demon land outside Taniguchi, and felt very uncomfortable, so it didn't chase it out immediately.

However, the magic dragon aura contained in the greedy sword still made it very excited. After hesitating for a moment, the frost dragon actually flew out of the valley mouth, leaving a series of icy paths in the air where it passed.

The frost dragon was extremely fast, and in the blink of an eye, it caught up with the greedy sword, and with a big gulp, an extremely cold aura enveloped the greedy sword.

If it is shrouded in this cold breath, even if the greedy sword has the power of Li Muran's Sky Devouring Phantom, it will not be able to escape!

The greedy sword immediately spat out the blood of the demon dragon, and then pierced the void, narrowly escaping.

The frost dragon was overjoyed, it glanced at the blood of the demon dragon, and immediately sensed that it was not too much, but it was quite pure, and there were no other harmful impurities. The frost dragon gulped down and swallowed the blood of the demon dragon into its belly!

Li Muran didn't do anything in this ball of demon dragon blood, he knew that the frost dragon might be more familiar with the demon dragon's blood than himself, as long as there was a slight strange aura, I am afraid that it would not be able to draw out the frost dragon.

As soon as the frost dragon swallowed the blood of this demon dragon, ten thousand sword lights suddenly shone in the air around him. Eighty-one small swords soared into the sky with brilliant sword light, and then disappeared into the void, and instead a layer of sword light barrier with a size of dozens of miles appeared, enveloping the frost dragon.

"It's done!" Hua Yuncong was overjoyed, the figures of him, Liu Chenfeng and the others suddenly appeared in a small hill more than ten miles away, and a clever hidden formation was withdrawn around them.

Li Muran also flew out of the Demon Valley, he recalled the greedy sword back in his hand, and guarded the mouth of the Demon Valley, those low-level demonic beasts in the Demon Valley did not dare to rush out at all.

Only then did the frost dragon realize that it had been ambushed, its eyes were full of anger, it opened its mouth and spewed, and a stream of cold breath spit out, turning into layers of frost, and in the blink of an eye, it filled the sword array. Even the sword light barrier was attached with a thick layer of frost.

Hua Yun hurriedly activated the power of the sword array, and a large amount of spiritual power was withdrawn from the countless spirit stones in the array, turning into fierce sword light and slashing towards the frost dragon. Liu Chenfeng and Sword Spirit also each held a formation flag, injecting their own pure sword qi into the sword array to cheer for the sword array.

In an instant, ten thousand swords slashed together, and the momentum was amazing!

The frost on the sword light barrier was all cut down in an instant, and the frost around the frost dragon was also defeated invisibly. The sword light was everywhere, and the frost dragon could not avoid it, and even the frost dragon's incomparably hard scales had fallen on the subtle sword marks.

"This frost dragon's frost scale armor is really hard!" Hua Yuncong said in shock: "If you change to an ordinary spirit body stage demon beast, if you are slashed by this ten thousand swords, it must have turned into a ball of flesh, but it is almost undamaged!"

Li Muran nodded secretly, he had already heard from the demon soul that there were many descendants of demon dragons in the demon world, and whether the bloodline of these descendants of the demon dragon was pure or not could be judged from the form, in addition, the scales on their bodies also directly reflected the strength of the bloodline. The more powerful the demon dragon bloodline, the more invulnerable the scales on its body are, and the real demon dragon scales rumored to have reached the realm of indestructibility and indestructibility, it is said that only true immortals have the ability to destroy it, this strength is similar to the dragon bone of a real dragon.

The frost dragon scales of this frost dragon are so strong, which also shows that its demon dragon bloodline is very strong. It's a pity that it fell into the sword array, as long as the spiritual power of the spirit stones in the array is not exhausted, as long as the array sword is not destroyed, the power of the sword array will be endless!

Ten thousand sword lights continued to slash towards the frost dragon, however, on the scales of the frost dragon, layers of frost emerged, dissolving the power of the sword light that had changed greatly, relying on the defense of the scales, the frost dragon actually resisted wave after wave of sword array attacks.

"This frost dragon's body is inevitably too strong!" Liu Chenfeng and the others' faces changed slightly. Even the sword array could hardly be injured, and it was conceivable that their swords could not kill it.

The frost dragon relied on the hard frost scale armor, and even ignored the sword light that slashed in, but used his claws to tear the sword light barrier of the sword array hard.

The tip of the claw claw grasped the sword light barrier, and patches of piercing cold light appeared, making a sharp and piercing sound, and countless sword lights collapsed and dispersed, and several slender cracks were torn by it.

Li Muran was shocked, although Hua Yuncong's sword array was incomparably powerful and magnificent, it was still a single swordsmanship after all, like most swordsmanship powers, it was known for its sharpness. However, this frost dragon has an extremely strong body, which happens to be very restrained in swordsmanship. No matter how subtle and varied the swordsmanship is, if you can't cut through the opponent's body, it will be useless.

Fortunately, the defense of this Nine Xuan Sword Formation is also extremely strong, and even though the frost dragon rushes left and right, and tries its best to tear and grasp, it is not damaged, and the frost dragon can never escape.

Suddenly, the frost dragon raised its head to the sky and let out a long roar, and its howl seemed to have an extremely strong piercing force, all the way to the depths of the Demon Valley!

In the Magic Valley, bursts of commotion appeared, and a large number of demonic beasts jumped and flew up one after another, surging towards the exit of the Magic Valley!

"This frost dragon is the 'master' of this valley, and it actually has the ability to mobilize these demonic beasts to work for it!" Li Muran's heart sank, and he hurriedly sacrificed the greedy sword, which turned into a giant purple python and guarded the exit of the magic valley.

As soon as those low-level demonic beasts flew to the mouth of the valley, they were swallowed by the purple mangs transformed by the greedy sword, and then their divine thoughts disappeared and they fell into the valley with no breath. Seeing this scene, all the demonic beasts couldn't help but be shocked, and their movements slowed down slightly.

However, urged by the dragon roar of the frost dragon, more and more demonic beasts were flying towards here, and there seemed to be some high-level demonic beasts in the distance who were also alarmed!

Li Muran's heart sank, he knew that with his own strength, he couldn't stop so many demonic beasts from rushing out, and the top priority was to kill that frost dragon first.

He didn't dare to pity those immortal fire talismans anymore, and immediately stretched out his fingers and flicked a spell into the sword array.

Hua Yun realized that the array flag in his hand shook, and a small hole appeared in the sword light barrier, which was put into the magic trick that Li Muran sacrificed, and then immediately closed.

"Boom!" A loud bang came from the sword array, and the flames rose into the sky, filling the entire sword array.

The sword array barrier was also torn apart by a powerful flame impact at this moment, shattering inch by inch!

"This, the power of this rune array is inevitably too strong!" Hua Yun's face changed drastically, and he clearly sensed that the barrier of the sword array was directly destroyed by an unstoppable explosion, and the sword array was broken!

This Nine Xuan Sword Array is Hua Yuncong's proud work, with complicated layouts, but it is known for its power. Unexpectedly, Li Muran just used a talisman array to forcibly break it down in an instant!

With such a strong power, Hua Yun couldn't help but think that if he was in that talisman array, under this explosion, there would definitely be no bones left!

Liu Chenfeng was also shocked, none of them had ever seen Li Muran use such a powerful method. With such a means, even if it is to kill a spiritual monk, I am afraid it is not surprising!

After the fire dissipated, the frost dragon did not exist again. Its flesh had been completely destroyed, but there were a large number of gray scales scattered in the air—none other than its natal dragon scales.

Li Muran was taken aback, he couldn't imagine that these dragon scales were so strong, and they hadn't all been destroyed in the rune array of the Immortal Fire Talisman!

As soon as the frost dragon died, those demonic beasts in the Demon Valley lost their "master" summons, and at the same time, they were frightened by the huge movement outside the valley and retreated to the valley one after another.

Li Muran flew to the side of the talisman array, waved his robe, and put away those scales one by one.

Suddenly, a flash of blood flew out of a scale, intending to flee towards the Demon Valley.

Li Muran's eyes were quick, and he didn't have time to think about it, a Heaven Sealing Talisman was sacrificed, and a spatial barrier was formed in an instant, firmly enveloping this ball of blood light!

With the use of the Heaven Sealing Talisman, this ball of blood light naturally had nowhere to escape.

"This is the Demon Dragon bloodline contained in the Frost Dragon?" Li Muran looked at the blood dragon with surprise and joy, and praised with excitement in his eyes: "This is much thicker and more powerful than my original Demon Dragon bloodline!"

Li Muran's method immediately changed, stretched out his fingers and flicked, he followed a method taught to him by the demon soul at the beginning, to subdue this more powerful demon dragon blood.

Wisps of demonic qi popped out of Li Muran's hands, turning into black qi and entangled towards the blood dragon layer by layer.

The blood dragon kept dodging, but it couldn't break out of the seal of the Heaven Sealing Fu in a short period of time, as the black qi enveloping the blood dragon became more and more, the blood dragon's actions became more and more inspirable, and finally, it was completely trapped by a cloud of black qi and couldn't move.

Li Muran stretched out his hand and grabbed it, ingested the blood dragon shrouded in black qi into his hand, and then put a few sealing talismans close to him, and then put them in his sleeve.

Li Muran withdrew the Heaven Sealing Talisman and smiled at Liu Chenfeng and the others: "Hehe, this demon dragon bloodline is harmful to ordinary spiritual cultivation, but it is of some use to the next, so you are welcome!"

Liu Chenfeng nodded: "The killing of the Frost Dragon is mainly due to Senior Uncle Li, and the spoils of war are naturally handed over to Senior Uncle." ”

Hua Yuncong also nodded and didn't say anything.

Li Muran took out a jade box from his arms, threw it to Hua Yuncong, and said: "Hua Daoyou's sword formation also contributed a lot, but the spoils of war were swallowed by the subordinates, I'm afraid it is a little inappropriate, this spirit of the demon bird will be given to Hua Daoyou as compensation." ”
