The fire crow, which was more than ten meters wide, exuded a terrifying power, covering the sky above Gu Immortal City, and the scorching aura made people's hearts palpitate.

This Mu Yuan is not only a genius in his own right, but also a powerful rune treasure, and his strength can be exerted to the level of a first-grade spirit rune!

When a talismanic master encounters Mu Yuan, he is basically dead and lifeless.

Gu Immortal City's expression was solemn, calm, and he snorted lightly, but he was not afraid at all, although he was a seventh-grade mortal talisman master, but his mana cultivation was the ninth layer of condensing qi, cultivating the Qiankun Immortal Technique, the Xuanji Immortal Body, and his strength was even more terrifying than that of a monk in the Divine Sea Realm.

Even if it was facing a real first-grade mortal talisman master, Gu Immortal City had the confidence to suppress it!

"Wind tornado!"

Gu Immortal City snorted coldly, cast another spell, and in an instant, a violent wind erupted, and a tornado that rose into the sky appeared with his body as the center.

The tornado rose up like a long dragon soaring into the sky, whining in the air, the wind blade was like a knife, and the flowers, trees, soil, sand and stones within a radius of more than ten meters were all twisted into pieces!

The huge fire crow that fell from the sky collided with the tornado in an instant, and the sharp and terrifying wind blade twisted the fire crow into layers and collapsed.

Before the fire crow's attack landed on Gu Immortal City, it had already turned into strips of flames and rolled up into the sky, turning into nothingness.

"What kind of magic is this?"

Mu Yuan in the sky retreated again, his expression shocked.

Without any rune fluctuations, such a terrifying attack erupted in such a terrifying way, which was simply unheard of.

The Holy Day Sect is a major sect in Yunzhou, and Mu Yuan, as the son of an elder, has been exposed to it since he was a child, and he can be regarded as well-informed, but he doesn't know that there are such techniques in the world!

"Sorcery, then you will die under this sorcery!"

Gu Immortal City's voice was cold, and his mana had already been exposed, so he didn't plan to stay alive.

The tornado rushed up into the sky, like a long dragon, rushed in front of Mu Yuan in the blink of an eye, trying to twist Mu Yuan into it.

Even the giant fire crow that was equivalent to a blow from a first-grade spirit rune master was twisted apart by this tornado, Mu Yuan knew how terrible this technique was, if he was twisted into it, he was afraid that he would be strangled to the point of separation of flesh and bones, and there would be no corpse.

Mu Yuan retreated in the air, and the speed of the flying charm was very fast, avoiding the attack of the tornado, but he did not escape.

"No matter what kind of evil art you have, the talisman is the right way in the Immortal Fu Continent, do you think that this evil art will not be able to break you?"

Mu Yuan's voice was full of murderous intent, and a talisman appeared in his hand, revealing a terrifying aura.

It's a spirit-level talisman!

Elder Mu Ye of the Holy Day Sect specially refined a spirit-level attack talisman for his son Mu Yuan!

"Fire Spirit Spear, kill!"

Mu Yuan drank loudly and sacrificed the talisman in his hand.

In an instant, the talisman turned into a huge flame spear ten zhang long, revealing earth-shattering might.

With just one blow, the tornado that soared into the sky dissipated in an instant, and the attack power of this flame spear was terrifying, even if it was a first-grade spirit rune master, it could be killed in an instant.

Gu Immortal City was shocked in his heart, and felt the terrifying threat, even if his Xuanji Immortal Body defense was strong, there was also a death crisis, which showed how terrifying the power of this spear was!

The Flame Spear broke through the 'Wind Tornado' and continued to kill towards Gu Immortal City, as fast as an arrow.

Buzz –

The bone sword on Gu Immortal City's back suddenly trembled, blooming with brilliant light, and soared into the sky.

"Qiankun Sword Technique!"

Gu Xiancheng shouted, pinched the sword trick in his hand, and the bone sword burst out with ten zhang sword rays, refining swordsmanship in the sky, casting peerless attack and killing techniques, and colliding with the flame spear.

The Qiankun Sword Technique is the strongest offensive method in the Qiankun Immortal Technique, and it is a big hole card for Gu Immortal City to kill many strong enemies in the Tianyuan Continent.

With the current cultivation of Gu Immortal City, it is still very difficult to use this sword technique, and the mana is a little insufficient, and in the Immortal Fu Continent, it has never been used.

However, facing the danger of life and death at this moment, Gu Immortal City couldn't care so much, forcibly casting the Qiankun Sword Technique, no matter what, Mu Yuan had to be killed today, otherwise the Immortal Fu Continent was so big that there would be no place for him.

Boom –

With a bang, bright sparks sputtered in all directions, and the huge flame spear was actually cut into pieces by the sword.

In the sky, Mu Yuan's heart trembled, this was the talisman that his father used to save his life, even if he met a first-grade spirit rune master or a first-grade spirit rune beast, he could kill it in an instant.

In the periphery of the Tianfu Mountain Range, it is basically impossible to have traces of spirit rune beasts, and it is unlikely to meet spirit rune masters, Mu Yuan has such runes, it should be the strongest and invincible, and he can kill whoever he wants.

However, this terrifying talisman attack was resisted by the other party, which made Mu Yuan's heart furious.

Poof-

Gu Immortal City blocked the opponent's talisman attack, but it also vomited blood due to the forcible use of the Qiankun Sword Technique, spurting out a large mouthful of blood.

Seeing Gu Immortal City vomiting blood, Mu Yuan's heart was much more relaxed, and his heart said that this was a normal performance, if Gu Immortal City easily resisted the spell blow of the 'Fire God Spear', it would be hell.

The talisman of the 'Spear of the God of Fire', Mu Ye refined a total of three for his son Mu Yuan, which can be said to be extremely important, Mu Yuan saw Gu Immortal City vomiting blood, and the original idea of wanting to flee in horror suddenly stopped, and took out another 'Spear of the Fire God' talisman and threw it towards Gu Immortal City.

"Your evil magic has a great backlash on the body, see if you can catch the 'Vulcan Spear' attack again, hehe......!"

Mu Yuan sneered, looking down at Gu Immortal City in the sky, Gu Immortal City had already vomited blood just now, if he did it again, would he be directly hit by the backlash and fall to the ground?

The corners of Gu Immortal City's mouth curled slightly, revealing a hint of a smile, it was true that he was counterattacked, but his Xuanji Immortal Body was very powerful, and the impact of the backlash on him was not particularly serious.

Spit out a mouthful of blood just now, it was Gu Xiancheng who took advantage of the situation and deliberately made the other party light the enemy, so that he would not flee immediately, Mu Yuan was really fooled.

"Dead ——!"

Gu Xiancheng drank coldly, and once again used the Qiankun Sword Technique, the bone sword bloomed with brilliant light, and the sword burst out more than ten zhang, slashing towards the 'Fire God's Spear'.

The Vulcan Spear was once again defeated, and Gu Immortal City couldn't help but spit out a mouthful of blood again, but this one was much less than the first time to vomit blood.

The bone sword in the sky, the light fainted slightly, and then the Gu Immortal City was injected with mana again, and the bone sword light bloomed, turning into a cold light, killing Mu Yuan.

Gu Immortal City defeated the second attack of the 'Fire God Spear', and also launched a counterattack, which was a result that Mu Yuan expected, and he was simply terrified, and hurriedly destroyed the flying talisman and retreated quickly.

The speed of the flying talisman was more than forty meters in one second, how could it match the attack speed of the bone sword, and it was caught up almost in the blink of an eye.

When the bone sword came, Mu Yuan's heart was so frightened that he couldn't resist it at all, and he hurriedly threw out the third 'Fire God Spear' talisman.

Boom –

There was a bang in the sky, and the spear of the Vulcan shattered, and the bone sword also faded, and it was repulsed by a distance.

Mu Yuan's eyes were extremely frightened, and he hurriedly controlled the flying talisman to escape.

However, in the blink of an eye, the bone sword bloomed with brilliant light again, killing Mu Yuan again, this time, Mu Yuan no longer had the 'Vulcan Spear' talisman to resist!
