At this time, more Howling Moon Wolves rushed towards the mana barrier of Gu Immortal City, their mouths widened, and one after another moonlight burst towards Gu Immortal City.

Boom Boom Boom Boom ......

A series of explosions sounded, and Gu Immortal City took a few steps back before standing firm, and the mana barrier shook violently.

The remaining Howling Moon Wolves, there are still nearly forty of them, and they haven't all attacked just now, but the attack power has already made Gu Immortal City feel a huge pressure.

Dozens of howling moon wolves attacked at the same time, and their attack power was almost comparable to that of a spirit-level first-grade rune beast, and although the mana barrier could be defended, it was very reluctant.

If this attack comes a few more times, the mana barrier will have to be shattered.

Gu Xiancheng's heart tightened, he still underestimated the strength of this group of howling moon wolves, as a group of demon beasts, dozens of them together, even if they encountered a spirit-level first-grade rune beast, they could all be killed.

Vine wall charm!

Gu Immortal City retreated, casting a spell, and countless vines appeared, tangled around the mana barrier.

Divine Speed Talisman, Divine Power Talisman, Gu Immortal City had already been activated, and the speed at which he retreated was extremely fast, and he burst back more than thirty meters in one second!

The speed at which the Eight-Rank Divine Speed Talisman was raised was still about eight meters per second, but the mana cultivation of the Gu Immortal City had broken through to the ninth layer of Qi Condensation, and the body cultivation of the Xuanji Immortal Body had also risen sharply in all aspects, but the extreme speed had reached the point of more than twenty meters per second!

While retreating, Gu Xiancheng raised his hand and threw out a talisman!

There are ten talismans, all of them are heavy wood talismans, and a large number of giant trees fall from the sky, each attacking a howling moon wolf.

The mana's control over the bone sword has not been interrupted, and the speed of the bone sword is still as fast as a shadow, coming and going like the wind.

In the blink of an eye, another Howling Moon Wolf died under the attack of the bone sword.

Moreover, the top ten giant trees fell, and the Howling Moon Wolf also fell down.

Spells are destroyed by mana, and the stronger the mana, the stronger the spell.

Even if the talisman of Gu Immortal City is only a mortal-level sixth-grade, the mana is the mana of the ninth layer of condensation, and it is still the ninth layer of condensation qi of cultivating the Qiankun Immortal Technique, which can be compared with the mana of the first layer of the Divine Sea Realm.

With such a powerful mana, destroying the mortal-level sixth-grade rune, the power is naturally very terrifying, far superior to the mortal-level eight-grade rune, and almost not inferior to the mortal-level ninth-grade rune.

In addition to the mortal-level nine-grade Howling Moon Wolf can resist, the mortal-level seventh-grade and eighth-grade can't resist, so it is naturally smashed over, the mortal-level eighth-grade Howling Moon Wolf is not seriously injured, and the mortal-level seventh-grade Howling Moon Wolf was smashed by a heavy wooden talisman, but it is difficult to even climb up and loses its combat effectiveness.

Whew—

The wolf king roared angrily, it didn't expect that this human with strange attack methods had so many talismans on his body, and the wolves suffered a big loss at once, and lost several more.

The wolf king roared angrily, and also burst out with a moon-like light, which was thicker and brighter than the ordinary moon whistling wolf, and the power was more terrifying.

The moonlight-like light burst out for tens of meters, instantly hitting the vine wall outside the mana barrier.

With a click, the vine wall shattered!

With the vine wall talisman destroyed by the strong mana of Gu Immortal City, even the mortal-level nine-grade rune is difficult to break through in one blow, so it can be seen that the attack power of the wolf king is much stronger than the mortal-level nine-grade rune beast, not much worse than the spirit-level first-grade rune beast.

The vine wall talisman weakened the attack power of the wolf king, and the mana barrier shook slightly, and it resisted this light attack.

Whoosh –

Gu Immortal City's speed exploded to the limit and retreated, and he once again cast the vine wall talisman to strengthen the defense of the mana barrier.

At the same time, the mana controls the attacks of the bone sword constantly, and continues to kill the Howling Moon Wolf!

The Wolf King's reaction was sensitive, Gu Xiancheng ignored the Wolf King first, and after killing all the other Howling Moon Wolves, he concentrated on dealing with the Wolf King, with the speed and flexibility of the bone sword, it was not difficult to kill the Wolf King.

The speed at which Gu Immortal City retreated was much faster than the speed at which the Howling Moon Wolf could run at its limit, and only the Wolf King could catch up with his speed, and in just a few breaths, the distance between Gu Immortal City and the ordinary Howling Moon Wolf exceeded twenty zhang, exceeding the attack limit of the Howling Moon Wolf.

This meant that Gu Immortal City only needed to withstand the attack of the Wolf King.

And Gu Immortal City controls the attack of the bone sword, and how far the divine sense can cover, how far it can be killed, which means that Gu Immortal City can kill the enemy more than two hundred meters apart, and the Howling Moon Wolf is all in his attack range.

Although there are vine wall talismans to strengthen the defense of the mana barrier, the attack power of the wolf king is really strong, and the mana barrier is shaking more and more fiercely when he attacks again and again.

In such a state, Gu Immortal City needed to maintain the mana barrier, which required a large amount of mana and could not support it for too long.

The situation in Gu Immortal City is not good, but the effect of killing the Howling Moon Wolf is very high, the Howling Moon Wolf can't judge where the bone sword is attacking from, and it can't reflect the speed of the bone sword, and it kills one accurately.

In a maximum of two breaths, a Howling Moon Wolf died.

Gu Immortal City had been retreating in the direction of the cave where he was hiding, and by the time he retreated to the vicinity of the cave, he had already killed more than twenty howling moon wolves.

But his situation was also very embarrassing, as soon as the wolf king attacked, the mana barrier shook violently, and it was almost on the verge of collapse.

It was precisely because the wolf king saw that Gu Immortal City was going to be unable to resist it, so he continued to hunt down Gu Immortal City when the wolves suffered heavy losses.

Seeing that the power barrier was about to be forcibly broken by the Wolf King, Gu Immortal City finally arrived at 'home', and his body retreated into the concealment and defensive formation.

In front of him, the figure of Gu Immortal City was suddenly lost, and there was no breath of Gu Immortal City, and the wolf king was taken aback.

Phew-

Immediately, the wolf king opened his mouth and spit out a moonlight light, shooting towards the place where Gu Immortal City disappeared, with a bang, the void shook, and a translucent light mask appeared, resisting the wolf king's attack.

The translucent light shield is extremely difficult to find in the night, but it can't hide from the night vision eyes of the wolf king, and when he sees that this light mask is very similar to the mana barrier of Gu Immortal City, he knows that Gu Immortal City is hiding inside.

Boom Boom Boom Boom ......

The wolf king continued to spew out moonlight to attack, and the top ten howling moon wolves who were still alive soon caught up, and also attacked continuously towards the magic circle light shield, causing the magic circle light shield to shake for a while.

The defensive magic array arranged by Gu Immortal City was much stronger than his direct mana defense, and for a while, these Howling Moon Wolves couldn't break through.

In the defensive array, as soon as Gu Immortal City entered the cave, he sat on the ground with his ass, and hurriedly ran the Qiankun Immortal Technique, absorbing the innate aura and replenishing the mana!

Outside the light shield of the magic circle, the wolf king led more than a dozen howling moon wolves to attack with perseverance, and most of the howling moon wolves were killed by Gu Immortal City, and the rest were ferocious, vowing to tear Gu Immortal City to pieces.

About half an hour passed.

Suddenly, a dangerous aura came out from within the circle, and with a flash of coldness, the bone sword burst out.

A howling moon wolf was attacking the magic circle, and was cut off by the bone sword that suddenly attacked, and he whimpered for his life.

Phew-

The flying bone sword suddenly turned around and slashed at the other Howling Moon Wolf.

Gu Immortal City's mana had not yet fully recovered, but the body was hidden in the magic circle, and it was more than enough to control the bone sword to kill these howling moon wolves.
