Gu Immortal City's mana cultivation is too advanced, he is already a first-tier cultivator of the Divine Sea Realm, and the strength of his mana can be compared to the fourth-fold cultivator of the Divine Sea Realm, as long as he has enough rune power, he can continuously improve his rune cultivation. Pen, fun, and www.biquge.info

If the conditions for breaking through the spirit rune master are reached, for Gu Immortal City, breaking through the spirit rune master is not a problem, and there is no bottleneck.

When he reached the realm of the Ninth Rank Fan Talisman, the power of the runes in Gu Immortal City was much stronger than that of the Seventh Rank Fan Talisman, and he tried to cultivate the 'Heaven Destroying Vine' again, and finally, there was no situation where the runes collapsed, which proved feasible.

The strength of the rune power of the Nine Rank Fan Rune Master was already enough for the cultivation of the first layer of the 'Heaven Destroying Vine'.

As for the other problem of cultivating forbidden arts, comprehension, Gu Immortal City had experience in cultivating many spells, and the spells that were a hundred times more complicated than the Heaven Destroying Vine, Gu Immortal City had refined them all, and there was no problem at all in cultivating the Heaven Destroying Vine with his understanding.

As early as a few days ago, when he watched the secret of the 'Heaven Destroying Vine', Gu Immortal City had deduced it countless times in his mind, and he had already understood the cultivation of the first layer of the Heaven Destroying Vine thoroughly.

Moreover, the mana of Gu Immortal City is too strong, and there is a divine sense induction, and the mana controls the power of the runes, which is extremely accurate, and there is no mistake.

Although the rune model of the Heaven Destroying Vine was complex, it was only a matter of time before Gu Immortal City was successfully constructed.

Three full days later, a complete 'Heaven Destroying Vine' rune model appeared on Gu Immortal City's arm, which looked like a vine more than an inch long, with leaves next to it.

Gu Xiancheng used mana to destroy the rune model of the Heaven Destroying Vine, and suddenly, the rune model stood up, grew into a real vine, and moved to the palm of Gu Immortal City, the vine was lush and green, revealing the life breath of the wood attribute.

Gu Immortal City destroyed the Heaven Destroying Vine to attack, and the vines suddenly exploded, and the technique stretched out dozens of meters and slapped on the ground, smashing some stones into pieces, and the ground also pulled out an inch-deep ravine.

Gu Immortal City shook his head, the power is not good, it may be similar to the Nine Rank Fan Talisman.

The vine of destroying the sky, only when the cultivation has reached the second step, can it be regarded as a successful cultivation, and now it is a semi-finished product, not much different from ordinary talismans.

Only by integrating the spirit wood essence into it is the real forbidden art, with a powerful and terrifying strength.

Gu Immortal City took out all the essence of the spirit wood in the rune space ring, continued to cultivate the vine of destroying the sky, absorbed the essence of the spirit wood, and refined it into the rune model.

The process of absorbing the essence of the spirit wood is very slow, the key is not the speed of absorption, but the absorption of the essence of the spirit wood, and refining into the rune model, this process is extremely complicated, much more complicated than the construction of the rune model, and there is no room for error.

Even with the conditions of Gu Immortal City, with divine sense induction and powerful mana control, it was only carried out slowly.

If you change someone, the speed is probably more than ten times slower than his, and the chance of error is ten times greater.

The essence of the spirit wood is limited, Gu Immortal City does not dare to waste it, in case the essence of the spirit wood here is just enough to cultivate to the first level, if it is wasted a little, wouldn't it be that the first layer of the vine of destroying the sky will not be able to be cultivated?

If he can't practice the vine of destroying the sky, Gu Immortal City will not be able to activate the rune teleportation array, and if he can't activate the rune teleportation array, Gu Immortal City will not be able to do without the Muyun Cave Mansion, although he can open the valley, he can't stay here for a lifetime!

So, it's okay to slow down, but be safe and don't make mistakes.

Time passed day by day, which was a great drain on the spirit of Gu Immortal City, however, Gu Immortal City had cultivated the Yuan Shen, although the Yuan Shen was severely damaged by the Heavenly Dao and dispersed into spiritual power again, it was also much stronger than other talismans.

There is no problem with continuous high-precision cultivation for several days and nights.

After a full five days, Gu Immortal City finally let out a long breath, and the model of the Heaven Destroying Vine in his hand bloomed with a millimeter, revealing a terrifying aura with a slight shock.

The first layer of the vine of destroying the sky, the cultivation was successful.

The essence of the spirit wood, there is still a little bit left, Gu Immortal City put it away, the spirit wood essence needed by the second layer of the vine of destroying the sky is ten times that of the first layer of cultivation, and that little bit is not enough to stuff the teeth.

"Let's try the threat of the Vine of Destruction again!"

Gu Immortal City's mind moved, and his mana worked, and when he destroyed it, he destroyed the Heaven Destroying Vine Rune model on his arm.

The vine of Heaven Destroying seemed to be given life, and it suddenly turned into a lush vine and moved to the palm of Gu Immortal City.

"Go-!"

Gu Xiancheng snorted softly, stretched out his palm forward, and the mana continued to destroy the Heaven Destroying Vine, and the Heaven Destroying Vine suddenly grew more than a hundred meters, like a long whip.

The vine whip was slammed down, and the sound of breaking the air came from the air, and in the next moment, the vine of the Heaven-Destroying Vine slammed into the ground, almost from the top of the mountain to the foot of the mountain.

Boom -

With a bang, countless boulders exploded, and the entire mountain peak was pulled out of a huge ravine, and the ground trembled violently.

The power of this blow was more than a hundred times stronger than the previous blow.

If he faced Su Hongcai and the other fifteen Spirit Rune Master disciples of the Holy Sun Sect now, Gu Immortal City would be able to kill them all without using the hole cards of mana at all, and directly destroying the Heaven Destroying Vine.

"Collect!"

Gu Immortal City's mind moved, and he withdrew his mana, and the rattan more than a hundred meters long instantly shrunk, turned into an inch long, and returned to the original place of his arm, returning to normal.

A small mark, but with such terrifying power, the power of the forbidden art is indeed extraordinary, no wonder the number is scarce, it is too difficult to create a forbidden art.

The first layer of the Heaven Destroying Vine was refined, and Gu Immortal City could activate the rune teleportation array and leave the Muyun Cave Mansion.

However, Gu Immortal City was not in a hurry, he took out a few talisman secrets in the rune space ring, all of which were mortal-grade top-grade.

He killed so many genius disciples of the Holy Sun Sect, the Holy Sun Sect would definitely not let him go, leaving the Muyun Cave Mansion, unless he escaped from Yunzhou, the Holy Sun Sect would definitely kill him, and he would inevitably have to fight.

There are two spirit rank nine-rank talisman puppet protectors, Gu Immortal City is not afraid of the Holy Sun Sect, naturally will not escape, and the battle with the Holy Sun Sect is inevitable.

When you need to do it yourself, your mana can't be exposed in front of everyone, and it's necessary to learn talismans.

Gu Immortal City's mana cultivation was much higher than that of Fu Dao cultivation, and learning mortal-level high-grade runes was easy for Gu Immortal City.

In just one day, Gu Immortal City had learned three mortal-level high-grade talismans - Falling Wood Talisman, Wooden Shield Talisman, and Wooden Leaf Talisman!

"It's time to leave, Mu Ye, if you kill dozens of people from my ancient family, I will definitely want you to die without a place to be buried, and go to Huangquan with your son Mu Yuanhuang!"

Gu Xiancheng got up, his eyes narrowed slightly, revealing a strong killing intent.

He destroyed the vine of destroying the sky, the vine grew, and wrapped around the rune teleportation array, and the teleportation array gradually bloomed with light, and the seal connection was broken.

Soon, the seal was broken, and the surrounding rune marks appeared, flickering with light, and a dazzling beam of light rushed out of the teleportation array.

Gu Immortal City walked into the teleportation array, was wrapped in a spatial force, shuttled through the void in an instant, and left the Muyun Cave Mansion.
