When Chu Yun's body and Eryi Zhenren discussed important matters, the clones in the battlefield palace finally had an important appearance......

The clone searched in the study for a long time, and collected all the information related to the soul sacrifice formula.

These are the first-hand information of the monarch to study the soul sacrifice formula, and they are extremely precious.

Whether or not the soul sacrifice recipe can be cracked in the future depends on these materials.

After he flipped through the books on the shelf, he vaguely felt that something strange seemed to exist on the other side of the shelf, constantly attracting him.

The spiritual power in the sea of qi was even a little restless.

Chu Yun's heart tightened, he could feel that there was a wonderful attraction that seemed to attract his instinct, prompting him to want to get closer.

It's like a moth encountering a fire, and can't help but lean over.

Chu Yun cheered up and carefully moved the bookshelf on the ground.

Moving away, he saw a clean wall. All the buildings in the palace were so hard that even the Cave Void Master could not destroy them, and so was the solidity of this wall.

Chu Yun stared at the wall for a while, but there was a very inconspicuous crack on the wall.

If you don't look closely, you can barely see this tiny anomaly in your eyes.

And the attraction that Chu Yun felt in his heart clearly stemmed from this small crack.

"How could such an impregnable palace be damaged?" Chu Yun was very suspicious, and then touched the small slit with his finger to test it.

With this touch, he clearly felt that the spiritual power in the sea of qi became active.

"This little crack seems to be very close to my spiritual power?" Chu Yun said to himself in his heart.

He knew very well that the spiritual power in his sea of qi was obtained from cultivating the soul sacrifice technique, which was different from ordinary spiritual power.

And since this small crack is close to spiritual power, it means that the small crack is likely to be related to the soul sacrifice technique.

"Could it be that there is something in this small crack that is very hungry for my spiritual power?" Chu Yun looked at the wall and couldn't help but wonder if there was something on the other side of the wall.

Unfortunately, there are no mechanisms in this study.

In desperation, Chu Yun had no choice but to use the simplest and most brutal method - bombardment and indiscriminate bombing.

Since there might be something on the other side of the wall, try blasting it!

Chu Yun immediately gathered spiritual power in his palm, and when the spiritual power appeared, it immediately turned into a gloomy demonic qi.

Whew!

Chu Yun slapped more than ten palms on the small crack in succession.

Cracks in the walls are naturally the easiest to break.

However, Chu Yun didn't expect that he could easily break the wall, he just wanted to try it at first.

Unexpectedly, this time, he showed that something was wrong.

After his demonic qi bombarded the wall, it seeped into it along a small crack. It was as if on the other side of the rift, something would attract demonic energy.

Such a result inevitably surprised Chu Yun a little.

"Since it's something that absorbs demonic energy, it's definitely close to me, and in that case, this thing shouldn't pose much of a threat to me......"

Chu Yun pondered for a while, no longer looking forward and backward, and successively shot out the demonic qi transformed by spiritual power towards the small crack.

He knew that it would not be easy to break the wall, so he simply let all the spiritual power be sent into the small cracks, just like feeding.

In the process of "feeding", the cracks are gradually changing strangely.

In the cracks, a dark purple luster appeared, which was very strange and penetrating.

Chu Yun felt more and more that on the other side of the crack, there was a very terrifying thing.

It was this thing that kept absorbing his spiritual power.

In the process of absorbing spiritual power, this thing is like a dead thing gradually gaining life.

With such a scene, Chu Yun didn't know whether it was good or bad.

After a while, something that made Chu Yun even more stunned happened:

As the spiritual power was absorbed, the cracks gradually enlarged and expanded, and the walls were actually breaking automatically.

Impenetrable walls, which just began to self-destruct?

Could it be that the cause of everything is the things that are buried in the cracks?

Chu Yun was shocked and suspicious, and continued to convey his spiritual power, feeding the things in the crack.

In order to speed up, he hollowed out and swallowed another Qi Ying Pill......

Eventually, the crack widened, and large swaths of the wall shattered into pieces and fell to the ground with a clatter.

The things in the crack finally appeared in Chu Yun's sight.

In the middle of the wall, there was a half-cut sword body.

The sword body continued to absorb Chu Yun's spiritual power, and the original dead gray sword body gradually emitted a faint purple light.

Only then did Chu Yun understand that the crack had appeared because of this sword.

The front half of the sword was inserted into the wall, and the tip was just sinking into the wall.

Because of Chu Yun's spiritual power nourishment, this sword was rejuvenated, and at the same time, it shook open the already cracked wall.

When he saw this sword, Chu Yun's eyes couldn't help but become hot.

It's not that he's greedy for the baby, but that he's in an uncontrollable mood and desperate to pull the sword out.

It's a pity that he can only see half of it now.

As for the hilt of the sword, they do not know where.

Of course, this is not because the sword is broken. Rather, the other half of the sword was not exposed.

Where the wall broke, an invisible light curtain barrier appeared.

And this sword was pierced through from the other side of the light curtain. However, the sword did not pass through completely, only halfway.

The half that came through it just disappeared into the wall.

Chu Yun looked at this layer of light curtain and immediately made a judgment - the other side of this layer of light curtain was another space that had been opened up.

He had just entered this study, and in fact, he had come from the palace to the study, a small independent space.

At this time, the light curtain behind the wall also clearly separates the study space from another space.

Chu Yun stared at the junction of the sword body and the light curtain, and his breathing couldn't help but be a little short.

Because, he knew that the monarch would find a secret place to cultivate the soul sacrifice technique, and the space on the other side was likely to be the cultivation ground.

And that's not the point...... The point is that this sword, which exudes purple light, is impressively the same as the pattern on the palace gate.

On those eighteen pictures, the sword in the hand of the person representing the monarch happened to be similar to the sword in Chu Yunxian.

"This sword, could it be that the monarch shot it from the other side of the space?" Chu Yun silently guessed.

Because this Chu Yun's clone didn't know that the Demon Lord was "suddenly obliterated" ten thousand years ago, he didn't dare to infer why this sword was inserted here.

Chu Yun's clone rarely appeared in this layer of light curtain penetrated by the sword, so he naturally wanted to find a way to find out.

So, he tried to pull the sword out. However, it is obviously useless to drag it like this.

For now, he can only continue to "feed" spiritual power to this sword......
