Xu Jingchuan looked indifferent, and put the "Brief Explanation of Derivation" in the palm of his hand and looked at it for a while.

The speed of flipping through the book is extremely fast, as if it were ten lines at a glance, and it only takes a few tens of seconds to turn the book over the last page.

In the end, Xu Jingchuan closed the book after reading it and handed it to Wang Bei.

His expression did not change in the slightest, as if it was as cold as ice that would not melt for ten thousand years, and he put the book in his hand casually and placed it diagonally two inches below his waist.

Wang Bei didn't need to immediately reach out to pick it up.

Although the posture of the person in front of him is casual, there is always a sense of domineering in it.

For example, the gods who are in charge of all things do not ask what mortals think, but decide everything by the destiny of heaven.

The act of handing over the book lasted for a moment.

Xu Jingchuan was a little impatient, glanced at Wang Bei lightly, and calmly transferred the book back to the shelf.

Without asking questions or explaining, he left the row of bookshelves with a sidestep step.

Wang Bei took two steps forward for no reason, and looked around at the criss-crossing bookshelves, but there was a trace of turmoil in his heart.

He leaned on the plank with one hand, struck a pose that he thought was cool, and thought faintly, "This person is just like me, just as weird." ”

Maybe it's a common problem for lonely people, and they can't see another lonely guy.

Wang Bei laughed self-deprecatingly, and moved the book "A Brief Explanation of Derivative Texts" down.

After flipping through the pages, I took the book with me and got a borrowing certificate, and then left the library.

......

With a specific textual explanation, the words on the bead notches are explained one by one.

There are even many different characters in it, but fortunately, Wang Bei did not practice according to his superficial understanding of words, otherwise there would be problems in practicing sooner or later.

The verification was not a heavy task, and it only lasted for half an hour before the translation was almost complete.

The cultivation secret of the black knife technique, which was a knife technique, finally appeared completely in front of Wang Bei's eyes.

Just take a cursory look.

Wang Bei said with some sighs: "If I had obtained this sword technique earlier, I would not have been so powerless when I fought." ”

The Black Knife Technique is also a non-grade knife technique.

Although there is a mental method, there is no move, the core is how to operate the strength, with a point of internal force combined with weapons to play thirteen points of strength.

It can be described as a martial art that reduces ten meetings with one force.

However, in order to perform the black knife technique, the demand for weapons is relatively high.

Whether the length of the blade is moderate, whether the weight of the knife is heavy enough, whether the deflection angle is up to the standard, whether the thickness of the knife surface is thin enough...

Basically, you have to recast a new knife, otherwise it will be difficult to meet the requirements of the black knife technique.

Put aside the matter of black knife art for the time being.

Wang Bei immersed himself in his mind and began to cultivate the Heavenly Transformation of the Body.

In the many unknown corners of the body, bursts of twisting and changing power suddenly appeared.

The surrounding aura seemed to have been plundered, gathering in Wang Bei's various acupoints.

In the air on the upper floor of the dormitory, a huge vortex of spiritual energy appeared out of thin air, and the wind and waves were calm in the middle, but the outer circle seemed to be chaotic like stirring the wind and clouds, frantically absorbing the spiritual energy within a radius of thousands of miles.

In the end, all of them turned into a fine thread, and the mud cow poured into Wang Bei's bottomless body.

The cultivation progress suddenly skyrocketed from 23 percent in a row.

Twenty-nine... Thirty-seven...

Boundless madness climbs.

However, in the depths of the Inner Emperor Academy's primary courtyard, including the beginning of the intermediate courtyard, someone gradually let out an exclamation.

"Hey, why is the aura gone..."

"Damn, what the hell happened, I almost broke through to the next star, but why is this aura suddenly gone..."

......

In the Heavenly Dao Academy above the Nine Heavens, several Battle Venerables who were in the process of cultivation also suddenly opened their eyes.

"It's strange, the aura of this Nine Heavens has always been very stable, why did it suddenly become a lot thinner. ”

"Could it be that there is a god of war powerhouse who has misappropriated a thousand miles of spiritual energy to perform a killing move of more than seventy stars, and it shouldn't be..."

......

The sudden change in aura thousands of miles away attracted the attention of countless people, and even many people got up to find the source of the aura mutation.

More people were made mistakes in their cultivation because of this change, and suddenly, injuries of a large or small amount, or even a regression of the realm, appeared in the Inner Emperor Courtyard.

All kinds of resentment and irritability spread.

provoked a large number of people in the imperial court to scold angrily for this.

As the Inner Imperial Courtyard entrenched on the mountain range where Emperor Yangu's body was incarnated, the aura has always been known for its stability, and some truly strong people do not dare to easily move the aura of heaven and earth on a large scale to fight, so most of the cultivators in the Imperial Courtyard can concentrate on cultivation without worries.

But in this way, when the aura changes, countless people will be affected.

Suddenly, a huge campaign to find the culprit began.

Vowed to teach the guy who caused the catastrophe a good lesson, although this is the case, but if they really encounter any strong people of the god of war, these guys are afraid that they will not dare to go to Xingshi to ask for the guilt, and in the end, they just let the high-level of the Imperial Court come forward to warn them.

But before everyone could find the source of the mutation, the turbulent aura disappeared.

Wang Bei, who was staying in the dormitory, suddenly wrinkled, and opened his eyes with some annoyance.

Originally, I didn't know what was going on with this body heavenly transformation technique, but the progress of cultivation suddenly increased a lot, starting from twenty-three percent and surging to sixty-seven percent now.

It skyrocketed by 44 percent in an instant.

Wang Bei thought that he would be able to completely complete the transformation of his physique at this moment, but he was suddenly stuck, and Wang Bei was momentarily stunned, no matter how much he urged the cultivation method, he couldn't improve the progress at all.

I really don't know what the hell is going on.

"This broken exercise, if it doesn't work, don't rise so much, and it makes people look forward to it in vain. ”

Wang Bei didn't know at all how much impact his short period of cultivation had caused.

Those guys who were originally looking for the so-called "culprit" suddenly turned pale, and many people fell from mid-air.

But that still didn't change the panic in their hearts.

The aura within a radius of thousands of miles has been completely plundered!

How is this possible?

The aura between heaven and earth is connected, and even if the aura in one place is quickly consumed, the aura in other places will soon be replenished. Even if the God of War powerhouse can embezzle nearly a thousand miles of spiritual energy, it can still remove those spiritual energy blocks that are relatively easy to absorb and activate.

It affects the heaven and earth for a short time, but it can't completely empty the accumulation of spiritual energy.

But now, almost all the aura within thousands of miles has been hollowed out.

The aura of the outside world can only fill this large vacancy through slow infiltration, at least it will take ten days and half a month.

In other words, they would not be able to cultivate for nearly a few weeks.

I can only practice some martial arts and internal strength.

Suddenly, as soon as I thought of this, countless people fainted on the spot.
