Phew――

As soon as the black water leopard pounced, it was still dozens of meters away from Gu Immortal City, so it opened its mouth and spewed out a water arrow!

The water arrow was extremely fast, containing terrifying power, roaring!

Gu Immortal City's mind moved, destroying the mana, and suddenly forming a layer of mana barrier!

Bang -

The water arrow shot a meter away in front of Gu Immortal City, and a translucent light mask suddenly appeared, and the water arrow shot on it, and with a bang, the water arrow collapsed.

The black water leopard was stunned, this kind of defense method, even if it was not in the memory of its inheritance, made it feel very weird.

"Wind Blade!"

Gu Immortal City raised his hand and slashed at the black water leopard.

Tear it up.

A hurricane condensed into a blade, like a flash of cold light, and instantly slashed towards the black water leopard!

The mana of Gu Immortal City was enough to compare with ordinary Divine Sea Realm cultivators, and its strength was comparable to that of a spirit rune beast, and the attack speed of this wind blade was much faster than that of the Black Water Leopard.

The black water leopard was still stunned, and just as its body was about to turn around and dodge, the wind blade had already slashed past its neck.

Blood spurted out!

The black water leopard's body turned around due to inertia, but its head fell directly to the ground, and the wind blade beheaded it, instantly fatal!

"It's so easy......!"

Gu Immortal City said to himself, and walked towards the Black Water Leopard, hunting mortal-level high-grade runic beasts, there was no pressure on him at all.

Walking next to the head of the black water leopard, the mana of Gu Immortal City condensed into a blade, which was extremely sharp, cutting the head of the black water leopard, and soon dug out the 'rune bone' of the black water leopard.

The rune bone is very large, about the size of two palms side by side, and there are natural runes on it, densely packed, the runes of the Black Water Leopard Society, there are rune models in the rune bones!

This rune bone is very helpful for runes to cultivate water-based runes, but it is limited to runes below the eighth rank of mortal level.

This black water leopard is an eight-grade rune beast, and its rune bone is a mortal-level eight-grade rune bone, for the runes above the eight-grade level, the effect is very small, for the runes of the eight-grade runes of the mortal level, the effect is average, and only for the runes below the eight-rank Dan level, it has a great effect.

For example, a seventh-grade mortal rune master, cultivating a mortal-level high-grade rune technique, and the effect of a mortal-level eight-grade rune bone is more impressive.

According to the market value, the mortal-grade seven-grade rune bone is worth one rune crystal, the mortal-level eight-grade rune bone is worth three rune crystals, and the mortal-level nine-grade rune bone is worth nine rune crystals!

If it is a spirit-level rune bone, it is much more valuable, even if it is just a spirit-level product, it is worth hundreds of rune crystals.

"As long as there are enough rune beasts, it is not difficult to earn rune crystals, and it will soon be enough to earn rune crystals that break through to the seventh-rank mortal rune master, even if it is the rune crystals needed to break through to the nineth-rank mortal rune master, it is not difficult to earn!"

Looking at the rune bone in his hand, the corners of Gu Xiancheng's mouth were slightly upturned, and he was in a very good mood, and muttered to himself: "There are very few rune beasts during the day, and it is not easy to find one, but the flesh and blood of the rune beast can attract other rune beasts to come, so I might as well wait here and wait for other rune beasts to take the initiative to come to the door." ”

Gu Immortal City looked around, and deep in the valley, there was a large boulder under the hillside, and there was a shadowed area below.

Gu Immortal City came here, entered the shadow area, and performed the invisibility technique, the translucent body was almost imperceptible in the shadows, and the stealth technique also concealed the breath, and the Gu Immortal City waited here to cast its own net in front of the other runic beasts.

After more than an hour, finally, a runic beast was attracted by the flesh and blood of the black water leopard, and it was a one-horned giant wolf with a body length of three meters.

Seeing that the head of the black water leopard was flattened off, this was obviously not a wound caused by the rune beast, but a human rune.

This made the one-horned giant wolf look around vigilantly, but found nothing, and after ensuring safety, the one-horned giant wolf began to eat the carcass of the black water leopard.

Gu Xiancheng recognized that this was a thunder-horned wolf, and when it matured, it was also a mortal-level high-grade rune beast, and this thunder-horned wolf was not particularly big, it should be a mortal-level seventh-grade rune beast.

Gu Immortal City approached silently, a wind blade slashed out, and the thunder horned wolf was eating, when it was cut off by the wind blade, and another rune bone was in his hand!

......

At the end of the day, Gu Immortal City waited for rabbits in this valley, and when it was almost nightfall, a total of five rune beasts were attracted to this valley by flesh and blood, and all of them were hunted by Gu Immortal City.

Coupled with the original Black Water Leopard, Gu Immortal City hunted a total of six rune beasts today, all of which were mortal-level high-grade rune beasts, among them, three were mortal-level seventh-grade, two were mortal-level eight-ranked, and one was mortal-level nineth-grade!

At the end of the day, Gu Immortal City harvested six rune bones, other talisman masters in the Tianfu Mountain Range, are all in groups of three or five, it is difficult to harvest so much in a day, Gu Immortal City alone, there is such a harvest, if it is known, I don't know how envious it should be.

When he was hungry, Gu Xiancheng took local materials, made a fire to roast some tender meat of Fu beasts, and ate to his heart's content, and waited for the rabbit all day, and he was not hungry.

It was getting late, and there were more rune beasts at night, and there were six rune beasts in this valley, and the flesh and blood would definitely attract a large number of rune beasts.

"If you continue to hunt rune beasts here at night, you will definitely hunt several times more in one night than during the day, but it will be easy for me to kill one, if there are more rune beasts here, I don't have good weapons, but I can't kill ......!"

Gu Xiancheng changed his mind in his heart, he wanted to continue hunting at night, but he was afraid of danger, after all, this place was already in the depths of the Tianfu Mountain Range, and all the people who infested were mortal-level high-grade rune beasts, and Gu Immortal City was afraid of being besieged by rune beasts.

However, when his eyes fell on the mortal-level nine-grade rune beast 'Iron Bone Bull', his heart moved: "This iron-bone beast, the bones are extremely tough, I am fatal to other rune beasts, but it took me a lot of effort to kill it, I can use its iron bones to refine into magic weapons, with weapons my lethality has increased greatly, and I am not afraid of small-scale rune beast sieges!"

Gu Immortal City's mana condensed into a blade, and soon the bones of the iron-bone barbarian bull were removed, and with the skeleton, he returned to the cave where the formation was hidden.

"Qiankun is really hot, refining-!"

In the cave, Gu Immortal City operated the Qiankun Immortal Technique, releasing the Qiankun True Fire, and his cultivation of the ninth layer of condensation Qi released the Qiankun True Fire was not strong, but it was more than enough to refine the bones of mortal-level rune beasts.

The impurities in the iron bones were incinerated by the true fire of Qiankun, leaving behind all the essence, just like the best metal materials, which are treasures of refining treasures.

"If there are other materials to cooperate, this iron bone essence can almost be refined into a spirit level magic weapon, but unfortunately there is no such condition, it can only be refined into a mortal level magic weapon!"

The entire skeleton was refined into an iron bone essence, and finally smelted into a bone sword, about a meter long and extremely sharp.

Gu Immortal City's treasure refining methods are exquisite, this iron bone essence is also a treasure refining treasure, although the bone sword refined is a mortal product, it is also an extremely powerful existence among mortal magic weapons.

Gu Immortal City stroked the bone sword in his hand and said to himself: "With this bone sword in his hand, even a mortal-level ninth-grade iron-bone brute bull can kill him with one blow!"
