Shiliu waited for the monarch for 10,000 years, but the monarch went behind her back to study the soul sacrifice technique.

Although Chu Yun couldn't understand the monarch's mood, one thing was certain, the matter of studying the soul sacrifice recipe could definitely not be known to outsiders.

The monarch is an important figure in the underworld, and if he studies evil techniques, once it is known, it will definitely not end well.

Chu Yun sat at the desk, carefully looking at the paper full of words and patterns.

On these papers, sure enough, they are all related to the soul sacrifice formula.

Chu Yun's current cultivation method is the Soul Sacrifice Technique, so he can easily make a judgment.

It's just that the paper on the paper is not a real soul sacrifice formula, but can only be regarded as a "half-finished product" of the soul sacrifice formula.

From the semi-finished product, Chu Yun probably experienced the process of the monarch's creation of the soul sacrifice formula.

In order to study this practice, the monarch made use of the souls of countless unjust ghosts in the hell. Later, he extended his claws to humans, and even the souls of some true immortals became experiments.

With so much effort, there is also a result.

The Soul Sacrifice Technique, which can be called an evil exercise against the sky, has finally begun to take shape.

These papers on the table can be regarded as the structure and draft of the soul sacrifice formula, and the complete soul sacrifice recipe was born on this basis.

It's a pity that Chu Yun's knowledge is limited, and he can't understand a lot of content.

He could only know that the soul sacrifice technique he cultivated originated from this. But there's more information on these papers.

"After a soul and a soul were absorbed by him, the monarch was indeed able to control the life and death of a cultivator. ”

"It's terrible, isn't it...... He can actually use his subordinates to improve his cultivation?"

"How many subordinates has he mastered to cultivate the Soul Sacrifice Technique......"

The more he looked at it, the more shocked Chu Yun's heart became.

He learned from this that the soul sacrifice recipe can actually be divided into two types, one is the "general chapter" and the other is the "second chapter".

The monarch cultivates the "general chapter", while his subordinates cultivate the "second chapter".

As a result, the subordinates sacrificed a soul and a soul to the monarch, which was equivalent to giving their lives to the monarch. As long as the monarch is willing, he can let the subordinates who cultivate the "second chapter" die at any time.

In addition, the cultivation of his subordinates will be improved, and the monarch will also benefit.

To put it bluntly, part of the results of the subordinates' cultivation will be obtained by the monarch for nothing. For example, Chu Yun continued to cultivate the soul sacrifice technique and devour the soul every day, and some of the power obtained from this would be directly transmitted to the monarch.

In other words, even if the monarch does nothing, he can gain power and improve his cultivation through his subordinates.

This way, by the monarch, called "passing".

However, that's far from all......

What made Chu Yun feel the most creepy was that once the monarch wiped out his subordinates, most of the power of his subordinates would return to the monarch's body.

In this way, it was recorded on paper by the monarch as "plunder".

In other words, if the monarch needs Chu Yun's power one day, then the monarch only needs to make a thought and wipe out the soul and soul that Chu Yun sacrificed, and then Chu Yun himself will die directly. And the power that Chu Yun had cultivated so hard turned into the use of the monarch - it was equivalent to being plundered by the monarch.

............

After Chu Yun saw this information, he only felt as if he had fallen into an ice cellar, and he felt cold all over.

The soul sacrifice technique turned out to be such a terrifying and cruel exercise.

If you just use your soul to cultivate, it's not terrifying. In fact, the soul sacrifice technique is a systematic exercise, and the ultimate goal is only to serve the monarch alone.

The monarch has mastered the soul sacrifice technique and mastered countless subordinates, which is equivalent to mastering the cultivation with no upper limit!

The monarch is like the king of a country, and the members of the Demon Cult are the people of the monarch. The people have to pay taxes to the monarch constantly, and the monarch can kill whoever he wants, and after killing, the wealth of the people will become the wealth of the monarch.

Chu Yun couldn't imagine how strong the monarch himself would be if he suddenly executed all the core members of the Demon Sect and then plundered the cultivation of so many people?

"With such a vicious and vicious technique, isn't there a way to crack it?" Chu Yun's breathing game was short, and he continued to read and check every detail.

In this regard, there is no direct way to crack it.

In Chu Yun's opinion, as long as the connection between the "general chapter" and the "second chapter" can be severed, it can be regarded as cracking the soul sacrifice formula.

In this way, the monarch will not be able to control the death of his subordinates, nor will he be able to use his subordinates to increase his own power.

The papers in the study are the results of the monarch's research.

If the monarch himself wants to use the Soul Sacrifice Formula, he may not consider any way to crack it, after all, the Soul Sacrifice Formula is only absolutely beneficial to him.

Although there is no way to crack it, if you understand these contents thoroughly, you may not be able to study a way to crack it. Chu Yun said silently.

After speaking, he put away all the papers on the table and put them into his space magic weapon.

These things must be taken out.

As long as it can be taken out, even if this clone is broken, it is worth it......

After doing these things, Chu Yun looked at the place where he came in again, and there was no change there.

At first, he was worried that Hexing would also find the mechanism of the door, and then break into the study.

But don't worry about it now.

Because, the mechanism can only be opened by using the spiritual power cultivated by using the soul sacrifice technique. Although this point is Chu Yun's speculation, it is basically an ironclad matter.

Otherwise, Queen Shiliu waited in the palace for a long time, wouldn't this organ appear?

Because, Shiliu has never practiced the soul sacrifice technique. So she would never touch the mechanism, and she would never have imagined that the monarch had built a study behind her back to study the soul sacrifice technique.

Chu Yun sat alone in the study, and he was not in a hurry to leave for a while.

He carefully sorted out the timeline, and then came to a conclusion - the monarch had basically completed the soul sacrifice before saying goodbye to Shiliu.

And what the monarch called "retreat and cultivation", the eight achievements are to cultivate the soul sacrifice technique.

Cultivating the Soul Sacrifice Technique requires a large number of souls, and the monarch definitely doesn't want Shiliu to know.

Not to mention the monarch's personality, in short, his relationship with Shiliu is absolutely excellent.

Therefore, he would rather hide from Shiliu to cultivate the soul sacrifice technique......

And what Chu Yun is thinking about now is, after the monarch and Shiliu say goodbye, where will he go to cultivate?

So, he searched in the study again, trying to find some clues.

............

At the same time, in Ningyin's territory.

Chu Yun, Ning Yin, and Yi Qing stood on a mountain peak that reached into the sky, looking in the direction where the battlefield palace was located.

The faces of all three of them were a little solemn.

What the doppelgangers in the battlefield saw and heard were known by Chu Yun here at the same time.

The half-finished soul sacrifice recipe in the study is naturally not a secret among these three people......
