Xu Yunyi thought about it for a moment and agreed to her older sister's request.

"Alright, I will think about it carefully for another day, and we can discuss it then."

She also knew that this sudden decision would be unacceptable to her older sister and younger brother, so she had to give them some buffer time.

After ending the Sound Transmission, Xu Yunyi sighed.

"I don't know whether hiding my brother-in-law's identity is good or bad."

She had just learned this information from Lu Qing'an's mouth while Luo Danhong was chatting with Lu Qing'an.

At that time, she was completely dumbfounded.

The Eternal Night Demon Emperor!

That was a legendary figure here in the Devil Realm!

An invincible existence!

Earlier, when she heard what Lu Qing'an said in the courtyard, she didn't quite believe it and thought it was a joke.

Unexpectedly, it was all true!

After careful consideration, she felt it was better to keep it a secret for now.

Don't affect her older sister's Dao Heart...

As for how long she could keep it hidden, she wasn't sure; it depended on her older sister's fate.

"Right, my older sister might send a Sound Transmission to Old He, so I should give Old He a heads-up first."

Xu Yunyi quickly sent a Sound Transmission to He Hong.

At this moment, He Hong, who was happily following along to choose a site for his future Artifact Refining Room, was completely dumbfounded after receiving Xu Yunyi's Sound Transmission and hearing the details of what had happened.

He looked at Lu Qing'an beside him as if looking at some ghost or deity, and said numbly, "Qing'an! You, you are the Eternal Night Demon Emperor?!"

As soon as he said this, everyone present looked at him strangely.

"You haven't told him about this identity of yours?" Xiao Qingyi looked at Lu Qing'an and asked.

Lu Qing'an said, "It seems I haven't yet."

Wang Duanshan laughed and said, "Haha, you only just found out? Hilarious! In the Devil Realm, besides the Eternal Night Demon Emperor, who else could make old fellows like us so utterly obedient?"

He Hong: "..."

My close friend turned out to be the Eternal Night Demon Emperor?!

...

Immortal Ruins.

Inside a grand hall.

After ending the Sound Transmission, Xu Qingying immediately sent a Sound Transmission to He Hong, only to find that the Sound Transmission could not get through!

"Huh? Why won't the Sound Transmission go through?"

"Older sister! I increasingly feel that the matter here is not simple!"

Xu Xuanyu gnashed his teeth, clenched his fists, and paced back and forth looking very impatient.

"I will send him another Sound Transmission. Perhaps someone happened to send him one just now," Xu Qingying said.

"Mother, Dad shouldn't be that kind of person..." Lu Zhengran's mouth twitched. Although he favored his mother more, he felt his father wouldn't set up such a vicious scam.

"Zhengran! Do you think you understand your dad? Since you are his son, do you know that he is a person from the Devil Realm?" Xu Xuanyu asked in a deep voice.

Lu Zhengran was instantly rendered speechless.

Xu Qingying took a deep breath, suppressed the annoyance in her heart, and sent a Sound Transmission once more. This time, she found that the Sound Transmission was successful.

"Old He, are you busy?"

"Qingying, is something the matter? I am indeed busy with things. If there's anything, make it short."

"Alright, it's like this. My younger sister suddenly said she wants to live there long-term..."

Xu Qingying recounted the situation she had just learned from her younger sister and then asked, "Is this matter true or false?"

"Oh, this matter? It's true. That ex-husband of yours is a bit special; I can only say he is terrifyingly strong, and he truly has the means to help your younger sister transform her cultivation, so you can rest assured. Your eldest daughter also successfully transformed her cultivation—I witnessed it with my own eyes. Furthermore, since I am here, I will take care of her. Is there anything else? If not, I'll get back to work."

When He Hong said this, he actually had a bit of temper in him.

He was very clear that Xu Qingying had wronged Lu Qing'an.

Now that Xu Yunyi could stay here, it could also be considered a form of punishment for Xu Qingying.

Of course, he also knew that Xu Yunyi staying here was also Xu Yunyi's own choice.

Lu Qing'an was truly too good to them; under such conditions, who wouldn't be willing to stay!

Upon hearing this, Xu Qingying knitted her brows tightly.

"Old He, are you sure everything you said is true? You aren't tricking us, are you?"

He Hong: "Qingying, you're being ungrateful here. When has this Old man ever lied to you? If you don't believe me, why did you even send a Sound Transmission to ask me?"

Xu Qingying: "..."

"Alright, I believe you. If there's nothing else, go ahead and get busy. We'll stay in touch later."

"Alright."

After ending the Sound Transmission, Xu Qingying furrowed her brows deeply.

It was true?!

Xu Xuanyu listened to the whole thing from start to finish, and at this moment, he stopped pacing back and forth, saying in a deep voice, "How could it possibly be true?!"

Xu Qingying lowered her gaze in contemplation for a moment and said, "We still must have Yunyi make a trip back!"

"Right! Exactly, I'm just afraid the second older sister won't come back..." Xu Xuanyu sighed.

"As long as she doesn't come back for a trip, then it must be false. If she really comes back and her decision remains the same as just now, then let her be," Xu Qingying said.

...

Devil Realm.

The sky was gradually growing dark.

After Lu Qing'an led Wang Duanshan and the others to choose the site, the remaining matters had nothing to do with him.

Wang Duanshan said they wanted to build the largest and most perfect Artifact Refining Room in the Devil Realm overnight. Since they couldn't help with the rest, Lu Qing'an returned to the courtyard.

As soon as he returned to the courtyard, Xu Yunyi came before him.

"Brother-in-law, I've decided to stay here in the future. However, my older sister is afraid that I made this decision against my will, so I might need to make a trip back... It might trouble you, Brother-in-law, to take me back to the Boundary Wall."

Lu Qing'an smiled and said, "It's fine, just a small matter. When are we leaving?"

It would be best if Xu Yunyi could stay.

"Let's set off directly. When I return here again, I will send you a Sound Transmission then," Xu Yunyi said.

Lu Qing'an nodded and said, "Should we tell the two children?"

Xu Yunyi: "I already told them just now."

"Alright then, let's set off."

He directly took Xu Yunyi, rose into the air, shattered the the void, and arrived at the junction of the Devil Realm and the Immortal Ruins in a single step.

"Then I won't escort you back. Pay attention to safety on the way back."

He wouldn't return to the Immortal Ruins; dropping her off here was enough.

"Alright, inside the Immortal Ruins, I won't encounter any danger."

Xu Yunyi smiled and nodded.

After speaking, the two waved to each other.

Xu Yunyi passed through the Boundary Wall and returned to the Immortal Ruins.

Lu Qing'an also returned to the courtyard.

About an hour later.

Xu Yunyi returned before her older sister overnight.

"Older sister, I'm back."

When she flew down onto the grand hall, she discovered that there were many people standing inside.

There were five people in total.

Xu Qingying, Xu Xuanyu, and Lin Qingxue were all present.

In addition, there were two Peak of the Great Emperor Realm powerhouses within the Immortal Ruins.

After seeing these two Peak of the Great Emperor Realm powerhouses, Xu Yunyi let out a sigh.

One of these two was the strongest Formation Master in the Immortal Ruins, and the other specialized in the Divine Soul. It seemed her older sister suspected whether her soul had been controlled.

As for calling over the strongest Formation Master here, it was probably also to make her take this person as her master and keep her here in the Immortal Ruins.

"Second older sister, come! Come sit down!"

Seeing that her second older sister had really returned, Xu Xuanyu let out a sigh of relief.

Xu Yunyi was pulled down to sit by Xu Xuanyu and said, "Fine, fine, fine. Can't I sit by myself?"

Now, whenever she saw this younger brother of hers, a wave of nameless anger would well up.

She really wanted to ruthlessly smack this younger brother's head a few times!
