At midnight.

Xiang Yun was taken to the Guigu Cave of Guigu University.

Ghost Valley Cave existed before the establishment of Ghost Valley University.

It existed even before the creation of the Guigu Dao Sect earlier.

This cave itself is a semi-enclosed secret realm, and its location is the core of the spiritual veins of Guigu Mountain.

Although the aura cannot be compared to the Overlord Holy Land, it is definitely several times higher than the ordinary cultivation secret realm, and staying in it for three days can be equivalent to normal cultivation for one or two months.

Furthermore.

Reiki is not the most important advantage of Guigu Cave.

Guigu Cave is said to be the place where the Taoist saint Zhang Liang and the Guigu Taoist Chen Ping discussed the Tao.

A saint-level existence, a near-saint-level existence, when the two of them discuss the Tao, it is enough to trigger the resonance of the law, thus permanently changing the situation of a region.

The Guigu Cave still retains the echoes and artistic conceptions of the two great powers, and the effect can be said that the entire cave is paved with enlightenment stones, and the speed of practicing exercises in the Guigu Cave is dozens of times higher than that of the outside world.

An exercise that would have been practiced in a year.

If you are lucky enough to enter the Guigu Cave, it is likely that you will not be able to fully master and integrate it in three or five days, which is the real strength of the Guigu Cave.

Even the students of Xichu University in Guigu Cave are only qualified to enter the cultivation of the top elites, and they are rarely open to the outside world, and this time because of the relationship between the famous school Fengyun Association, Xiang Yun won the cultivation qualification of Guigu Cave for three days.

This is enough to make many students of Guigu University envious, jealous and hateful.

When Xiang Yun passed through the many enchantments and guards, he officially walked into the cave in front of him, which didn't look particularly inconspicuous, but when Xiang Yun walked into the cave, he found that it was very different.

When you are in the cave of the Ghost Valley.

Xiang Yun didn't have the slightest feeling of being in a cave.

Because the space in the Guigu Cave is too open, it is like a pure natural cave maze, composed of countless spaces connected together, and at the moment of entering the Guigu Cave.

Some voices seemed to echo in Xiang Yun's ears.

This voice is like someone whispering in his ear, which is a bit similar to the feeling brought by the evil god stone rune, but there are some wits and opportunities in this space, which are similar to the evil god stone rune.

Although there are whispers.

Although the content is not audible.

But it doesn't give any irritability.

On the contrary, under such whispers, the heart lake is more calm and clear.

This small whisper seems to have some kind of divine power, which can suppress the demons in the heart, eliminate all distracting thoughts, and make people return to their true understanding and psychic, no wonder it has the ability to strengthen their understanding and practice speed.

"Interesting. ”

"Is this the echo left by Zhang Liang and Chen Ping in the Guigu Cave in the past? I didn't expect that 1,800 years later, it still reverberates in this place. ”

They seem to have become a kind of law.

Laws don't disappear with time.

Xiang Yun was not in a hurry to explore the Guigu Cave, but closed his eyes and listened carefully, as if trying to listen to the evil god stone rune, hoping to hear what was being said in these whispers.

Since records began.

For more than 1,000 years, many amazing and brilliant people have entered the Ghost Valley Cave.

Everyone hears the wonderful whispers that echo in the cave, but it is said that only those who are extremely gifted or have special luck can hear the contents of these whispers.

Of course.

This refers to hearing clearly.

Just hear one or two broken fragments.

No one has ever been able to get anything from the echoes of the Guigu Cave, and this ability to distinguish echoes is, in a sense, the best way to test one's luck and talent.

If Liu Yan'er enters here.

With her unfortunate luck, she will definitely be able to hear a large part of the content.

Liu Yan'er may not be able to understand these contents, but it is enough to just hear them, it doesn't matter what the content is, what really matters is the artistic conception of the sage's Taoism.

Even if you can only comprehend and grasp a little.

It is of great benefit to a Taoist monk.

Xiang Yun closed his eyes and listened carefully, no matter how hard he listened, he couldn't hear the mystery in it, occasionally one or two magic seals flashed in his ears, but the others were meaningless gibberish.

Could it be that my luck and talent are not enough?

No way.

If even the Xiang Cloud is not enough.

How many people can meet the standard?

Xiang Yun must not give up on this.

He simply stimulated the Heavenly Book Yuan Soul.

"The Book of Heaven tells me. ”

"What are these whispers? ”

Xiang Yun directly released a large amount of Yuan Force into the Book of Heaven, how strong the Yuan Soul of the Book of Heaven was, there were whispering voices everywhere nearby, even if Xiang Yun couldn't hear these sounds, it shouldn't be so easy to escape the perception of the Book of Heaven.

The Book of Heaven is quite versatile*, translator.

Whether it is a complex origin rune or a lost text whose meaning no one can grasp anymore, as long as you use the Heavenly Book to translate, you can generally get the most authentic information in it.

So Xiang Yun is trying.

The Book of Heaven may be able to translate these sounds.

If this can be done like this, then the meaning and value will be great.

In the past, Zhang Liang and Chen Ping discussed the process, didn't they all master it by themselves?

Xiang Yun was very much looking forward to this, so he continued to input Yuan Force into the Book of Heaven, and the Yuan Force on his body alone was definitely not enough, but the Guigu Cave was the core of the spiritual vein of Guigu Mountain, and Xiang Yun could use the Mountain and River Seal to transfer the power in it, so as to provide more powerful support to the Book of Heaven.

The Book of Heaven absorbs a large amount of Yuan Force.

Gradually, things are starting to change.

The first golden handwriting slowly appeared on the blank page of the Book of Heaven.

Xiang Yun's face was overjoyed, and he immediately strengthened the operation of the Heavenly Book, the second, third, and fourth...... More and more content appeared, and soon a chapter with a golden glow appeared in it, but it was still very vague and impossible to read clearly.

Ben just wanted to give it a try.

I didn't expect it to be possible.

This is an amazing discovery.

But just when Xiang Yun decided to make persistent efforts.

The Heavenly Book Soul suddenly underwent an unexpected change.

He felt that the Heavenly Book Yuan Soul suddenly released a strong light, and when the light gradually faded, Xiang Yun found that the Guigu Cave had changed, and the nearby environment seemed to be full of mosaics, becoming blurry and unclear.

Xiang Yun felt as if he was somewhere between the unreal and the real.

He calmed down and thought for a moment.

Xiang Yun quickly figured out what was going on, this must have been caused by the deduction of the Heavenly Book Elemental Soul, and there had been several times when Xiang Yun used the Heavenly Book Origin Soul to deduce, he would see such a real illusion.

If I didn't guess wrong.

The current Guigu Cave is a projection from 1,800 years ago.

Because of the incomparably powerful deduction power of the Book of Heaven, Xiang Yun directly saw the scene from 1,800 years ago.

Of course, what he saw was not completely restored, and the current ability of the Heavenly Book Yuan Soul was limited, which is why there were so many parts that were obscured by mosaics nearby.

Xiang Yun felt a voice coming from the cave in front of him.

Every word and every syllable seems to contain the true meaning of the Great Dao.

Xiang Yun couldn't understand but could feel the subtle artistic conception, he began to go in this direction, when he passed through several mosaic caves, he immediately saw two figures, one black and one white, sitting cross-legged in front of him, as if debating something.

The two figures brought Xiang Yun a feeling of being uplifted by the mountains.

In particular, that white figure was definitely the most powerful and highest-level of all the existences that Xiang Yun had come into contact with so far, and he didn't know if the evil god body in the evil god stone talisman could be comparable to this white figure.

The black figure is a little inferior to the white figure.

But Xiang Yun could also feel that his strength was on par with Fan Zeng.

An existence at the pinnacle of the Heavenly Realm, its strength is as strong as a million troops!
