Xu Xuanyu was left completely bewildered by his second sister's words.

Eternal Night Demon Emperor?!

He was actually the Eternal Night Demon Emperor?!

How is that possible!!

The Eternal Night Demon Emperor was not just a prominent figure over in the Demon Domain, but a terrifying existence whose reputation shook the entire Azure Cloud Continent!

The brother-in-law he had always looked down upon was actually the Eternal Night Demon Emperor?!!

You must be kidding!

This joke has gone too far!!

However, looking at the Sound Transmission Jade Slip that no longer transmitted a single sound, and confirming that the person currently talking to him was indeed his second sister, he fell into an even deeper silence.

Having grown up together with his second sister since childhood, he knew very well that she did not like to lie.

It might actually be true!

However, reason still caused him to remain silent for a good while before raising his doubt: "Second Sister, you... you must be pulling my leg..."

Seeing that her younger brother only reacted after a long time and his very first sentence was a question of disbelief, Xu Yunyi understood completely.

When she first learned that her brother-in-law was actually the Eternal Night Demon Emperor, she had also been so shocked that her scalp went numb, feeling as though the heavens were playing a massive joke on her.

Because ever since she was little, she had heard stories of the Eternal Night Demon Emperor, and she even held a shred of admiration for this powerful man...

"Little Brother, when have I ever lied to you? Furthermore, think about it: why did I trust brother-in-law so much even before he transformed my cultivation? Because I already knew that brother-in-law was the Eternal Night Demon Emperor."

Hearing this, Xu Xuanyu hurriedly said: "Then after you found out that brother-in-law was the Eternal Night Demon Emperor, why didn't you tell eldest sister directly? Then perhaps so many things wouldn't have happened earlier!"

"Are you stupid? Think about it, if eldest sister found out that brother-in-law was the Eternal Night Demon Emperor, what would she do? They have already divorced, and brother-in-law no longer has any lingering thoughts about eldest sister. What would happen if eldest sister's Dao Heart shattered?! This is also why I made you keep it a secret from eldest sister!"

Xu Xuanyu fell silent.

That was indeed the logic!

Only by cultivating to the absolute limit could their eldest sister, who possessed the Flawless Emperor Position, catch up to the Eternal Night Demon Emperor.

If she were to discover at this moment that her former man was the Eternal Night Demon Emperor, this would...

"Second Sister, I still find it a bit hard to accept this information. How could he possibly be the Eternal Night Demon Emperor..." Xu Xuanyu still couldn't connect Lu Qing'an with the Eternal Night Demon Emperor he had heard of countless times since childhood.

One looked exceptionally gentle to everyone, giving people the impression of an incompetent man. The other was the most powerful, invincible top killing god of the Demon Domain.

How could these two be connected!

This was too surreal!!

Furthermore, he had treated the Eternal Night Demon Emperor as his idol ever since he was a child!

Even now, he still took the Eternal Night Demon Emperor as his role model!

Every time he cultivated, he fantasized about one day becoming invincible across the Azure Cloud Continent and catching up to this role model...

Now it's great!

His second sister was telling him that the man he had always looked down upon in the past was actually his role model since childhood?!

His worldview had collapsed!!!

"Did you see the weapon I took out earlier?"

Xu Yunyi also knew that it was somewhat difficult for her younger brother to accept this information, because she knew that he had always idolized the Eternal Night Demon Emperor.

Thinking of this, she couldn't help but chuckle.

Well, the man you used to spurn and sneer at with sarcastic remarks every time you saw him is actually your childhood idol. Aren't you happy!

"I saw it..." Xu Xuanyu knew what his second sister wanted to say at this point.

"It was given by brother-in-law. Right now, Zixuan and Miaomiao both have them on them, and they each possess a treasure even more Advanced than the precious sword I took out earlier. They should be brother-in-law's most powerful weapons and armor," Xu Yunyi said.

Xu Xuanyu: "..."

He couldn't help but recall how his nephew, Lu Zhengran, kept showing off in front of him after obtaining that precious saber.

Well, Zhengran, whatever random things your older and younger sisters got directly crushed your precious saber by several hundred times!!

He was already starting to believe what his second sister said.

He was also gradually accepting this surreal and hard-to-accept news.

The brother-in-law he had always disdained in the past was none other than the Eternal Night Demon Emperor!

Because upon careful thought, the Eternal Night Demon Emperor, who had dominated the Demon Domain for many years, had suddenly vanished from the Demon Domain a little over a thousand years ago.

Rumor had it that the Eternal Night Demon Emperor went into seclusion. In order to breakthrough to a higher, even more invincible Realm, he suddenly went into seclusion for many years and never emerged.

Now, combining the time he first met this brother-in-law and when he heard about eldest sister's first meeting with Lu Qing'an, he discovered that it surprisingly matched the time the Eternal Night Demon Emperor disappeared from the Demon Domain almost perfectly!

Combined with what his second sister said, this was no longer as simple as a mere coincidence!!

"Second Sister, if he really is the Eternal Night Demon Emperor, then in his heart, do I no longer have any favorable impression left..."

Xu Xuanyu spoke with a miserable expression, his lips trembling as he talked.

He had been sarcastically disgusting this brother-in-law for close to a thousand years!!!

That was his idol!!!

Hearing her younger brother's words, Xu Yunyi finally couldn't hold it in and let out a chuckle.

"Ahem, Little Brother, um, brother-in-law is a pretty good person. Actually, he probably doesn't hate you..." Xu Yunyi tried hard to hold back her laughter, but her words of comfort still lacked confidence.

Because she truly wasn't sure.

Her younger brother had mentioned Lu Qing'an far too many times!

Xu Xuanyu: "..."

"Alright, let's leave it at that regarding brother-in-law," Xu Yunyi said.

"No, no, no! Second Sister, tell me a bit more?!" Xu Xuanyu hurriedly pleaded.

After a round of mental struggle, he still killed off his own self-esteem, his reason completely overwhelmed by star-struck emotions.

"What is there to say?" Xu Yunyi asked.

"Uh, tell me about how powerful you learned brother-in-law is after going over there this time! Last time brother-in-law displayed his strength here, it didn't feel like he was all that strong—just a little bit stronger than Lin Qingxue. Of course, that might be related to the restriction of the Boundary Wall and the fact that brother-in-law didn't fully display his strength."

Hearing her younger brother actually starting to make excuses for Lu Qing'an, Xu Yunyi wanted to laugh again.

This kid.

He was actually quite pure-hearted at core.

It was just that sometimes his mouth really begged for a beating.

"How strong is brother-in-law? Let me put it this way: I haven't been here long, but I have already seen four Demon Domain powerhouses far stronger than Lin Qingxue here. And when these powerhouses saw brother-in-law, their attitude—tsk tsk—was simply... how should I put it, let me think."

Xu Xuanyu's eyes gleamed as he said: "Revering him like a deity?!"

"Not quite. Brother-in-law is a very good person; they are utterly captivated and deeply devoted! They are afraid of making brother-in-law unhappy, yet they are extremely fond of him and really want to get closer to him!" Xu Yunyi said.

"Is that so! That's right! They definitely must be like that! Aside from that? What other powerful displays has brother-in-law made?" Xu Xuanyu asked again.

"Then there's the fact that my Innate Array Body awakened. Brother-in-law led us to a place called Skyfall Demon Cave, and there, even people with weak cultivation like us were able to enter for Body Tempering and cultivation. Even Miaomiao, whose cultivation isn't high, was completely unaffected! On top of that, I even awakened my Innate Array Body because of this! This is all thanks to brother-in-law! Moreover, I later heard from brother-in-law that he actually went all the way to the very bottom of Skyfall Demon Cave and fished out a mysterious Energy Body that seemed to be alive..."

Xu Yunyi spoke in great detail, her face full of admiration.

Just listening to this, Xu Xuanyu felt his heart surge with emotion.

"It's actually the Skyfall Demon Cave! I've heard of this place! Didn't rumors from the Demon Domain say that brother-in-law could only reach a depth of thirty or forty miles?! This time, he actually managed to reach the very deepest part?! Terrifying! Simply terrifying!!"
