The Heart-Questioning Array failed? The demonic fetus Liu Qingyu intervened, a perfect match for her expertise!

"How could this be?"

"It shouldn't be!"

"Little Brother Li, just now inside... did you really not feel any strange changes?"

Looking at Li Fan, who had walked out unharmed with a bewildered expression, Gu Zhiyun's eyes widened as she pressed for an answer, unwilling to give up.

"No."

Li Fan shook his head very seriously, his face full of sincerity.

"I went in with twelve points of vigilance, fearing I'd be caught in an illusion."

"In the end, I walked all the way to the end, and besides my vision being limited and getting slightly lost, absolutely nothing happened."

"I even thought... the Formation hadn't been activated yet?"

"..."

"Is that so?"

"Then I'll go try it myself!"

Hearing Li Fan's certain answer, Gu Zhiyun suddenly had a bad premonition.

But for the sake of thoroughness, she gritted her teeth and plunged into the mist-shrouded Formation.

A moment later.

When she walked out from the other side of the Formation with a dejected face, the result was already self-evident.

After stepping into the Formation, forget an illusion, she didn't even see a ghost of one!

This Formation, just as Li Fan said, was useless for anything other than blocking one's line of sight!

"How is it, Xiao Yun?"

Seeing Gu Zhiyun come out, Lin Xiyue, who had been waiting anxiously nearby, hurried to meet her.

"Sigh..."

"Sister Yue, the worst-case scenario happened after all."

Looking at Lin Xiyue's expectant gaze, Gu Zhiyun's small face slumped as she let out a heavy sigh.

"Lacking Illusionary Netherstone, the most core material..."

"This Heart Questioning Array... is still difficult to operate!"

In the Cangxuan Great Realm, to set up this Heart Questioning Array, the most primary and indispensable material is Illusionary Netherstone.

This kind of stone naturally comes with a hallucinogenic Domain and is the cornerstone for building illusions.

However, it's impossible to find Illusionary Netherstone in Great Xia, and there aren't even any substitute Materials with similar properties.

Consequently, in order to not rely on Illusionary Netherstone, Gu Zhiyun, relying on her extraordinary Comprehension Ability,

forcibly modified the layout of the Heart Questioning Array, attempting to use pure Formation-pattern circuits to simulate the illusion effect.

Originally, she thought that although her modified Heart Questioning Array might not be as powerful as the original due to the lack of Illusionary Netherstone,

it could at least barely run and give those students a little shock.

But now it seemed... she had simply overthought it.

Without the core material, this Formation was like a shell without a Soul; it was purely for show!

"I'm sorry, Sister Yue..."

Gu Zhiyun lowered her head, her voice a bit downcast.

"I overestimated myself."

"It seems the core material of this Formation really can't just be done without..."

"I messed up..."

She felt very bad inside, feeling she had let down Lin Xiyue's trust and expectations, especially since she had smugly guaranteed it before.

"It's okay, Xiao Yun, how can this be blamed on you?"

Seeing this, Lin Xiyue quickly stepped forward to take her hand and comforted her softly:

"You did your best!"

"After all, our conditions here are limited; we don't even have decent spiritual Materials. Asking you to set up a Formation with a pile of ordinary iron Ore was truly asking too much of you!"

"Being able to do this much is already very impressive!"

Lin Xiyue did not blame Gu Zhiyun.

Did she not know what their Great Xia was like?

They had nothing!

To be able to build a rudimentary Formation with a pile of scrap metal, Gu Zhiyun's value was already very, very high!

Strictly speaking, it was Great Xia's poverty that limited the performance of this Genius Formation Master, and it had nothing to do with Gu Zhiyun's skills.

"So... this Heart Questioning Array is temporarily unusable?"

Li Zhanjun, who was standing to the side, listened to their conversation and looked at the mist-shrouded but superficial Formation, suddenly finding himself in a difficult position.

"Then what means should we use next to test the students' state of mind?"

"If we don't have a gatekeeper and really let those with ill intentions in, it will be a major problem in the future!"

Since this Formation couldn't be used, they had no other tricks besides conventional methods!

But how could the effectiveness of conventional methods compare to a professional Heart Questioning Array from the cultivation world?

As soon as these words were spoken, everyone fell into deep thought.

Everyone frowned and pondered hard, but for a while, no one could think of a perfect alternative.

Seeing this stalemate, Li Fan couldn't sit still.

He subconsciously prepared to call out to Old Man Jian, who was resting inside the iron sword, wanting to ask if the well-traveled man had any other methods.

As it turned out, before he could act.

A voice as clear as a silver bell, yet with a hint of ethereal eeriness, abruptly rang out around everyone.

"Ya~"

"It seems you've run into some trouble~"

"Need some help~?"

The voice seemed both far and near, as if coming from all directions at once, carrying a hallucinatory quality that made one's mind sway involuntarily upon hearing it.

Everyone's expressions changed, and they instantly became alert.

However, when Lin Xiyue heard this voice, her eyebrows arched, and a playful smile tugged at the corner of her mouth.

"Hmph, caught you!"

The next moment, her figure flashed, and she disappeared from the spot like a ghost.

When she reappeared, she was holding a young girl by the collar, dressed in a fiery red gown, with an exquisite face that exuded a seductive aura.

"Sister Yu, you're being naughty again!"

"How dare you hide in the shadows and watch us?"

Lin Xiyue looked at the red-haired, red-eyed Liu Qingyu with eyes full of laughter, as if she had caught a student skipping class.

"Darn it!"

"Sister Yue, you're a bully!"

"Let me down! I'm going to tell Godmother! I'll tell her you're mistreating me!"

Being held by the back of her collar like a little chick by Lin Xiyue, Liu Qingyu instantly lost her mysterious and cold demeanor, stomping her feet in the air and protesting wildly.

"Alright, stop being naughty."

Lin Xiyue ignored her protest and instead leaned close to her small face, "threatening" in a low voice:

"If you don't behave, I'll have Ziyue come out and give you a good ideological education lesson!"

Hearing the name "Ziyue," Liu Qingyu, who had been flailing about, suddenly shuddered.

That sense of suppression originating from the depths of her Soul made her instantly behave.

"Don't, don't, don't!"

"Sister Yue, I was wrong, okay!"

"Whatever you do, don't let that icy woman out, I'm scared of her!"

Liu Qingyu immediately switched to a well-behaved and pitiful look, blinking her large eyes as she begged for mercy.

Seeing this, the surrounding people couldn't help but cover their mouths and chuckle.

After spending the last few days together, they were no longer surprised by Liu Qingyu's "dual personality."

And as early as when Liu Qingyu was first teleported over, they had already witnessed the side of this "Demon Fetus" personality.

To be fair, she really had the character of a complete little witch.

Quirky and moody, while not quite lawless, she often caused chaos, making people feel their scalps go numb.

What was worse was that because of her special Physique, no one could control her; even Lin Xiyue sometimes had no way to deal with her.

However, what was unexpected was.

Once when Liu Qingyu was being too rowdy, Lin Xiyue's Empress Clone—Ziyue—suddenly appeared.

Then, no one knew what means Ziyue had used.

Regardless, since that time, the fearless Demon Fetus Liu Qingyu immediately became well-behaved.

As long as she heard Ziyue's name, it was like a mouse seeing a cat, and she never dared to be disrespectful again.

It truly was a case of one thing being conquered by another!

"Sister Yu, what are you doing here?"

"Let's get this straight first: this is a place for serious business, no pranks allowed!"

Seeing Liu Qingyu settle down, Lin Xiyue nodded in satisfaction, let her go, and asked casually.

"Sister Yue, I've been wronged!"

Liu Qingyu smoothed out her messy red dress and said with a wronged expression:

"When was I pranking?"

"Didn't you guys run into trouble?"

"I specifically ran over here to help!"

As she spoke, she even puffed out her chest, looking like she was a "good person."

"Help?"

Lin Xiyue was stunned and looked at her suspiciously.

"You mean... you have a way to solve the current predicament?"

"Naturally!"

Liu Qingyu smiled confidently, her pair of eerie red eyes flashing with a Soul-stirring light.

She extended a slender jade finger and pointed at the failed Formation, speaking as if it were a matter of course:

"Isn't it just testing people's hearts and creating illusions?"

"This kind of small trick..."

"For me, it's effortless, as simple as eating or drinking water."

Hearing this, Lin Xiyue's eyes immediately lit up!

That's right!

How could she have forgotten this!

This girl was the Demon Fetus personality of the Innate Sacred Demonic Dao Fetus; she was naturally a master at playing with Heart Demons!

If she were to test people's hearts, it would absolutely be a perfect match!
