Because Brother-in-Law Is the Eternal Night Demon Emperor

Xue Tianfei had been standing quietly to one side. Her long-lashed eyes narrowed to slits as she watched Lu Qing'an pat Luo Danhong on the shoulder, and she clenched her teeth tight.

But Luo Danhong was not the only reason she was acting this way. Xu Yunyi was another.

Why had she suddenly decided to stay here?!

And why was Lu Qing'an so good to his ex-wife's younger sister? Was it because of his ex-wife, or because of Xu Yunyi?

From now on, these two beauties, whose looks were hardly inferior to hers, would be living here. The pressure on her was immense!

Could I really manage to be their stepmother?!

As Xu Yunyi listened to Lu Qing'an and watched his expression change, a warm current flowed through her heart, completely melting the coldness that had taken hold of it after the treatment she had suffered at the Immortal Ruins.

How could my sister have let such a wonderful man slip away?!

"Yunyi, if you have time, I'll convert your cultivation right now." Lu Qing'an turned to look at Xu Yunyi.

Xu Yunyi nodded decisively. "I have time right now!"

"Then come in." Lu Qing'an walked toward the room.

Xue Tianfei: "..."

You're not going to be alone together in a room...

Lu Qing'an sat cross-legged behind Xu Yunyi and circulated his power through both hands, beginning to convert her cultivation.

His cultivation strength was now several times what it had been before. He could convert the cultivation of anyone below the Great Emperor Realm with ease.

The principle behind converting cultivation was simple, rather like replacing a person's blood. He only needed to wash Xu Yunyi's meridians with vast quantities of Demonic Qi, then use powerful means to transform her dantian into one suited to cultivating demonic arts.

The condition for success was that he had to be a thousand or even ten thousand times stronger than the person whose cultivation he was converting.

With Xu Yunyi's level of strength, he could now complete the task effortlessly.

An incense stick's worth of time passed.

Lu Qing'an completed the task and calmly withdrew his power.

"Done. Take a careful look at your dantian and see if anything feels wrong."

Lu Qing'an stood up.

Xu Yunyi opened her eyes and stared at her hands in surprise.

As she circulated her power, dense Demonic Qi emerged from her palms.

It worked!

It really worked!

I knew it! If Brother-in-Law said it would work, then it definitely would!

"Brother-in-Law! Thank you!" Xu Yunyi rose to her feet and looked at Lu Qing'an excitedly, quickly bowing to him.

Lu Qing'an hurriedly stopped her. "You little girl, why stand on ceremony with me?"

"I have to. After all, we aren't really relatives anymore..." Xu Yunyi said with a wry smile.

Lu Qing'an shook his head with a smile. "Aren't you still Zixuan and Miaomiao's aunt?"

Xu Yunyi blinked.

"See? So nothing has changed between us. Don't let what happened between your sister and me leave any ill feelings in your heart. Make yourself at home here from now on. If anything happens, come straight to me. There's nothing here that I can't handle," Lu Qing'an said with a smile.

Xu Yunyi looked at Lu Qing'an, a peculiar feeling stirring in her heart, and gave a soft hum of assent.

"All right. Since you'll be studying formations under Luo Danhong, let her help you choose a cultivation art. She knows better than I do which Demon Domain art would suit you. If there's nothing else, take your time getting used to your current state. I'll head out first."

With that, Lu Qing'an left the room.

When Lu Zixuan and the others gathered around to ask how it had gone, he smiled and told them it had been a success.

Hearing that Lu Qing'an had truly succeeded in converting Xu Yunyi's cultivation, Luo Danhong looked at him with a new measure of respect.

He's terrifyingly strong!

He can even convert the cultivation of a Saint King Realm expert!

"Let her get some rest. Zixuan, make sure you put your younger sister to bed tonight. Don't disturb your aunt."

"Okay!"

Inside the quiet room.

Moonlight streamed through the gauze window onto the space before the bed.

Xu Yunyi sat cross-legged on the bed, her profile looking especially stunning in the moonlight.

She let out a long breath, having fully adjusted to her Demon Domain cultivation.

"I knew Brother-in-Law could do it!"

A smile appeared on Xu Yunyi's face, but when she thought of her elder sister and younger brother, a worried look replaced it.

Her sound transmission jade slip had been vibrating ever since she left the Immortal Ruins. Her younger brother had been sending her messages.

Now the jade slip vibrated again. She checked it and found that it was still her younger brother trying to contact her.

"Forget it. Little Brother had nothing to do with that matter. He must be very worried about me right now."

Xu Yunyi channeled Demonic Qi into the sound transmission jade slip, activating it.

"Second Sister! You finally answered me! Have you made it back there?!"

Xu Xuanyu's anxious voice came from the sound transmission jade slip.

Hearing her younger brother's tone, Xu Yunyi said, "Brother-in-Law brought me back. The two children were very happy when they learned I was staying here."

When Xu Xuanyu heard that Xu Yunyi was all right, he immediately breathed a sigh of relief. "Good, as long as you're all right. Second Sister, you really scared me earlier..."

Even now, he shuddered at the thought.

He had never expected his second sister to react so strongly!

"Is Elder Sister there with you?" Xu Yunyi asked.

Xu Xuanyu replied, "No, I'm in my own residence."

"If I hadn't done that earlier, I might very well have been confined for a long time. I couldn't even be sure whether I'd ever be free again. That Lin Qingxue is no good!" Xu Yunyi said gravely.

"So, Second Sister, Lu Qing'an really didn't use a Demon Domain secret art on you?" Xu Xuanyu asked.

"Of course not! Let me tell you, Brother-in-Law just helped me convert my cultivation! It was a complete success! Nothing went wrong at all!" Xu Yunyi knew her younger brother was genuinely worried about her, so she did not hide her situation from him.

"You're not lying to me?! You really succeeded in converting your cultivation?!" Xu Xuanyu asked in shock.

"It really worked! Honestly, Little Brother, you've always been far too prejudiced against Brother-in-Law. He's really, truly wonderful!" Xu Yunyi could not help feeling that Lu Qing'an had been wronged.

It was not that she disliked her younger brother. But every time she saw him treat such a good brother-in-law that way, she could not help trying to correct him.

Yet this boy refused to mend his ways no matter how many times she corrected him...

Xu Xuanyu fell silent.

"Second Sister, honestly, I'm confused now too. But I do have some common sense. You're already at the Saint King Realm. How could it possibly work...?"

Xu Xuanyu scratched his head. He had never been particularly clever to begin with, and his second sister often smacked him on the head. Now he truly had no idea how to make sense of this.

Xu Yunyi took a deep breath. She felt there was no need to keep it from her younger brother any longer.

"Little Brother, as long as you promise not to tell Eldest Sister what I'm about to say, I'll tell you something that will instantly clear all of this up for you!"

"I can't tell Eldest Sister? Second Sister, what are you trying to say?"

"Don't ask me! Hurry up and promise. Better yet, swear an oath! Swear that if you tell Eldest Sister, you'll never win the woman you love most!" Xu Yunyi forced Xu Xuanyu to make an oath that was particularly vicious as far as he was concerned.

"Second Sister! You! What's wrong with you?! How can I just swear an oath like that?!" Xu Xuanyu exclaimed.

"Are you going to swear or not?! If you don't, I'll stop talking to you!" Xu Yunyi threatened.

Xu Xuanyu thought it over. In the end, he gritted his teeth and swore the oath.

"All right, I've sworn it. Can you tell me now?"

"All right. The truth is, Brother-in-Law isn't simply a Peak Great Emperor Realm expert from the Demon Domain. He has another identity. He's the Eternal Night Demon Emperor of the Demon Domain!"

The moment she said this, both sound transmission jade slips fell utterly silent.

Two breaths passed without a sound.
