"Spiritual Knowledge", although it is called "perception", but its function is not to perceive, it is a formation that is directly refined with sand ink, and its difficulty and power are far beyond the reach of ordinary formations.

It's no wonder that as soon as Feixing heard about the "Immortal Enlightenment", he was directly intimidated.

Even then, in the Upper Realm, in the battle of Cangshan, the "Immortal Consciousness Knowledge" was not lifted in the end, but waited until the battle was exhausted, and that power dissipated.

In the more than ten years since then, whether someone has solved the "Underworld Enlightenment", Bai Liyue does not know.

At least in her memories before she fled to the ghost city, no one has been able to officially crack this "underworld knowledge".

For Bai Liyue, this "Spiritual Knowledge" can also be regarded as a breakthrough for her as a spiritual master.

Himself, as one of the three chiefs of Mingjian Mountain, Bai Liyue did not have much opportunity to study the formation in retreat.

Moreover, her rune array level at that time was already above that of most monks who cultivated rune arrays.

Generally speaking, the rune master is the most basic profession in the rune formation.

On top of the rune array division, there are many professions that engrave the rune array in other media, such as the weapon array master and the Dan array master, and above these, there is a unified focus.

No matter which medium class you choose, if you want to move up to the level of the rune array, you need to find the inheritance of the Spirit Master.

Fortunately, this heritage is already widely used.

In fact, not all rune masters can advance to become speech spirit masters, once they become speech spirit masters, they do not need to draw rune arrays by hand, but through words, manipulate those rune arrays to slowly form.

Of course, these words are different from ordinary words, and the specific way to use them depends on what the rune array master has obtained in the inheritance.

And above the spiritual master, there is the spiritual master.

The Spirit Master is not promoted to become a Spirit Master by reaching a certain level, but the comprehension of the rain itself.

While the Soul Master is drawing the rune array, some of the Spirit Master's words will suddenly stop at some point.

Generally speaking, when speech is interrupted, the disconnection of thoughts will be slower.

And this slight delay did not affect the formation of the rune array, and at this time, the spirit master understood that he had become a spirit master.

Becoming a spirit master requires not only strength, but more importantly, opportunity.

After all, no spirit master would deliberately interrupt the spirit of speech when drawing a rune array, and there were too few people who became spirit masters.

In Bai Liyue's memory, in this world, there are less than 100 speech and spirit masters who can finally become spirit masters.

And among these hundred people, there are also the deceased rune array masters.

Bai Liyue didn't know what the spirit master was up, but in her cognition, the path of the talisman array was endless, how could it be that a small spirit master could become the end?

After becoming a spirit spirit, Bai Liyue was questioned by many forces.

After all, before Bai Liyue, the youngest Yilingshi was already over 100 years old, and Bai Liyue at that time was only in her early twenties.

So there was the battle at the top of Cangshan.

It's ridiculous that Bai Liyue was led to the "Spirit?? The person of "Cliff" is none other than Chu Peining, one of the three chiefs of Mingjian Mountain who supported her the most after Bai Liyue became Yiling.

At that time, Bai Liyue had no doubts at all, why Chu Peining would take her to the empty "Spirit??" cliff", the main force is obviously near the "Xuantian Stream".

Chu Peining has always been Bai Liyue's trusted second senior sister, and she has always been.

It wasn't until she saw the [Soul Breaking Array] that Bai Liyue understood everything was just that she understood it too late.

Anyway, what is coming will come after all.

You can't hide.

What Chu Peining won't know is that the only person who can crack the "Underworld Enlightenment Knowledge" except Bai Liyue is her.

It was Bai Liyue, in order to prevent the "Underworld Enlightenment" from accidentally injuring her second senior sister, she specially added three precious materials and specially applied a protection program.

"Huh. Bai Liyue smiled.

She laughed at herself for being stupid.

Think about it carefully, how many of Chu Peining's actions in the past did not express her ultimate goal?

It's just that Bai Liyue was blinded by that trust, which led to such an ending now.

"Huh. Bai Liyue smiled again.

She laughed, thankfully, that wasn't the end.

She'll go back. After all, she still has to save Wushuang.

It's just that this kind of laughter, in the eyes of Feixing, is indescribably weird.

Lord Li Yue suddenly smiled "hehe", but there was nothing around.

When Feixing was about to ask, Lord Li Yue smiled strangely.

Could it be that Lord Li Yue was affected by the "Spiritual Understanding" and fell into what strange environment?

The more Feixing thought about it, the more likely it became, the "Immortal Enlightenment" that even he couldn't deal with, how could she deal with it with Lord Li Yue, a Huiyuan monk? Besides, Lord Li Yue's spiritual power was almost exhausted, and with the pill just now, it was estimated that he would not be able to recover eighty percent.

Feixing moved his eyes and made up his mind that if Lord Li Yue was really affected by the "Immortal Enlightenment", he must bring Lord Li Yue out.

The approach of the flying star, Bai Liyue actually knew.

She knew what she knew, but she thought that Feixing was just going to go all the way with her.

What Bai Liyue never expected was that Feixing would forcibly pull her out of the scope of the "Immortal Enlightenment".

At this time, Bai Liyue had already used her power to forcibly awaken the "Immortal Spiritual Understanding".

"Spiritual Knowledge" was created by Bai Liyue, and the spiritual power contained in it is the most affinity with Bai Liyue.

As soon as Bai Liyue handed over the spiritual power, the "Spiritual Enlightenment" was like nectar after a long drought, absorbing Bai Liyue's spiritual power.

But how can that little spiritual power be enough?

The energy of the "Underworld Enlightenment" had not been replenished for more than ten years, and as soon as he smelled Bai Liyue's spiritual power, it was like a cat seeing a fish, and rushed to pounce.

But Flying Star doesn't know that.

Feixing pulled Bai Liyue back two steps, but saw the brightest point at the light source rushing straight towards him, which obviously regarded the two of them as targets.

Feixing didn't think about it, and blocked his body in front of Bai Liyue, trying to block the "attack" of this "Underworld Enlightenment" with his flesh and blood.

But the "Immortal Enlightenment" was not a physical attack, and the flying star's body was in front of Bai Liyue's body, which was useless.

Those lights bypassed the flying stars, passed through the gaps, and surrounded Bai Liyue, like children begging for candy.

However, in the end, "Spiritual Knowledge" is "Spiritual Knowledge".

Even if they didn't make a move against Feixing, the rich spiritual power still overwhelmed Feixing.
