The mana cultivation has broken through to the sixth layer of condensation, and the next step is to improve the cultivation of the rune to the sixth rank of the mortal level, so that you can go to the rune pavilion to learn a kind of mortal-level middle-grade rune.

After Gu Xiancheng became a five-grade mortal talisman, he went to the Fu Pavilion to learn the second mortal-grade mid-grade talisman 'vine wall talisman', which is a defensive talisman that transforms into countless rattans like walls to protect the body around.

In the natal rune pattern, only by constructing three mortal-level six-rank runic models, can the rune cultivation continue to break through to the mortal-level seven-rank.

For the third mortal-level mid-grade talisman, Gu Immortal City was looking forward to it.

However, when Gu Immortal City used the mana of the sixth layer of condensation qi to attract the power of runes to cultivate, he found a problem, the heaven and earth aura of the Immortal Rune Continent was extremely deep, but the power of runes was not endless, and the concentration was much lower than that of heaven and earth aura.

In the previous cultivation, the rune cultivation in Gu Immortal City was too low, and the power of the runes needed was not very much, and the power of the runes attracted by mana was very surging compared to cultivation, so as long as the mana cultivation was broken, the cultivation speed of the rune cultivation was very fast.

However, after cultivating to break through the sixth layer of Qi Condensation, Gu Immortal City found that the power of the runes he had induced was not much more than when he was at the fifth layer of Qi Condensation!

This is because the concentration of rune power between heaven and earth is only so high, and Gu Immortal City has already attracted to the limit, which means that no matter how strong Gu Immortal City's mana is, the power of runes that can be triggered can only reach this limit.

In the Immortal Rune Continent, usually only after cultivating to the Spirit Rune Master would they feel that the concentration of the power of the runes between heaven and earth was poor, and it was difficult to support the cultivation needs.

At this time, unless you find a treasure place where the power of runes is particularly strong, you need the assistance of 'rune crystals' to continue your cultivation.

Rune crystal is an energy crystal condensed by the power of runes, and the concentration of solids is naturally much larger than that of gas, even if it is an immortal rune master, they can use rune crystals to cultivate, but it is a matter of more and less.

Now Gu Immortal City has felt the limit of the power of runes, which means that the current mana of Gu Immortal City is probably not much different from that of the spirit rune master.

For the Wupin Fan Talisman Master, being able to attract the power of the rune at the limit of the concentration between heaven and earth to cultivate is already a super fast speed, but for Gu Immortal City, he feels that the speed is a bit slow, and he can't maintain the rapid progress of the previous realms.

Sure enough, this time, the natal rune pattern was upgraded from the fifth rank to the sixth grade, and it took a lot more time than expected, and it took more than half a month to break through the cultivation.

"If there is no rune crystal, even if my mana cultivation breaks through the seventh layer of condensation, it will have no effect on the cultivation of the rune path, the power of the rune between heaven and earth is only so much, and the mortal level six to the seventh layer is a hurdle in the cultivation of the rune path, I am afraid that it will be difficult to practice in a few months!"

Gu Immortal Cheng secretly said in his heart, Fu Dao cultivation had broken through, but he was worried.

He is the young master of the ancient family in Luo Ancient City, and Gu Xuanhuang, as the acting head of the family, will naturally not treat Gu Xiancheng badly on the surface, and he has all the resources that should be given.

However, what the family gave to Gu Immortal City were coins, not runes.

Rune crystals, usually only need spirit rune masters to use, even if some mortal rune masters are more luxurious, in order to pursue the cultivation speed of the rune crystal cultivation, at least the cultivation of the mortal level, otherwise it will be very wasteful.

Because, the power of the runes that can be triggered by the mortal-level middle-grade rune master is limited, and the power of the runes contained in the rune crystals is very rich, but the cultivation is too low and the speed of absorption is too slow, which is no different from absorbing the power of runes from heaven and earth.

In other words, if Gu Immortal City wanted to apply for rune crystals from the family, it would have to at least reach the cultivation of the mortal-level seventh-grade, and the family might not approve such a luxurious move.

The speed at which a mortal-level high-grade rune master absorbs the power of runes is also limited, and cultivating with rune crystals is not much faster than directly absorbing the power of runes between heaven and earth.

Rune crystals are very valuable, unless it is the kind of big force that has too many runes to be used up, it will be given to the most important juniors to use rune crystals to cultivate when they are mortal-level high-grade rune masters.

The Gu family has not yet reached the point where there are too many rune crystals to be used up, which means that even if Gu Immortal City's rune cultivation reaches the mortal level seventh, eighth, or even ninth grade, Gu Xuanhuang will not give the rune crystals to Gu Immortal City for cultivation.

If Gu Immortal City wants rune crystals, they can only figure out their own way!

"If you want to earn rune crystals, you have to go to the sect task hall, complete the sect tasks, and you can get the sect's contribution points, and the contribution points can be exchanged for various treasures, and a little contribution value can be exchanged for a rune crystal!"

Gu Immortal City changed his mind in his heart, and at present, he could only think of a way to earn rune crystals through the Sect Mission Hall.

"Performing the task of the sect, there are gains and risks, it is not easy for my rune cultivation to break through the seven grades of mortal level, but it will not take long for mana cultivation to break through the seventh layer of condensation, with the richness of the aura of heaven and earth!"

"Cultivate to the seventh level of condensation in the sect first, and then go out to do sect tasks, it will be safer to be stronger! Even, if conditions permit, you can concentrate on cultivating mana in the sect!"

"Let the mana cultivation reach the ninth layer of condensation, or even break through the Divine Sea Realm, then you will be confident when you go out to do the task of the sect, even if you meet the spirit rune master, you are not afraid!"

Gu Immortal City thought in his heart, thinking that his idea was good, although the mana could not be used publicly, it could be used as a hole card, and in some times of crisis, it might save his life.

Gu Immortal City thought so, Yuan Feiying was not happy.

Yuan Feiying had been waiting for Gu Xiancheng to leave the sect, before and after, she had been waiting for almost three months, and Gu Xiancheng had been cultivating in the sect, which really annoyed her, she couldn't wait anymore.

Yuan Feiying was seventeen years old, and he was already an eight-rank fan master, at this age, this cultivation, was an absolute genius in Xuanyue Sect.

Her appearance is also the premier beauty among the disciples of the Xuanyue Sect, known as the first beauty of the Xuanyue Sect, even if she has a marriage contract with the young sect master of the Holy Sun Sect 'Dugu Liuyun', there are still a lot of people among the disciples of the Xuanyue Sect who regard her as the lover of their dreams and like her very much.

Moreover, Yuan Feiying is also the daughter of Yuan Zuo, the deputy sect leader of the Xuanyue Sect, and this identity is also the inner door of the Xuanyue Sect, which is also second to none, and no one can compare.

With a top-notch background, top-notch appearance, and top-notch talent, this makes Yuan Feiying also have a top-notch status in the inner gate of Xuanyue Sect!

Even the inner disciples of the mortal rank nine grades bowed down to her.

It's been a long time, and Gu Immortal City is about to forget the things in the waterhole, but women's hearts and eyes are not something that men can understand, and Yuan Feiying has never forgotten it.

Gu Xiancheng never left the Xuanyue Sect to go out, Yuan Feiying waited for nearly three months, and he really couldn't wait any longer, so he summoned a mortal-level nine-rank disciple from the inner gate.

Yuan Feiying held his head high, like a swan, looked at the Jiupin Fan Master in front of him, and said, "Luo Wufeng, looking for a favor from you, can you help?"

Luo Wufeng nodded hurriedly: "This is Luo's honor, Senior Sister Yuan, please obey the order!"
