Turning My Junior Sister into a Mary Sue In Xianxia Yuri World

Clang!

The sound of a sword rang out as the Snow Qiong of the Myriad Spirits Sword sliced through the air, leaving behind ten arcs of silver light.

Yun Yiyi fixed her gaze on Pei Lengxue’s figure ahead, her movements as graceful as a celestial maiden dancing. Yiyi felt both mesmerized and dazed. Although Pei Lengxue was using the same Shadowleaf Sword Art as Yun Xi, her fluidity and the sheer power of her swordsmanship far surpassed Yun Xi’s. In fact, in Pei Lengxue’s movements, Yun Yiyi caught a glimpse of their father wielding a sword.

Standing beside her, Yun Xi was evidently just as awestruck by Pei Lengxue’s swordsmanship.

But she didn’t stay stunned for long and patted Yun Yiyi’s shoulder, saying:

“You didn’t believe me before. I told you that when it comes to sword techniques, you and Jiujiu haven’t seen as much as I have. Pei Lengxue uses the Shadowleaf Sword Art, while Young Master Ye uses the Sword Inquiry Technique. Both techniques are direct-lineage skills, and only our lousy dad knows them. There’s no doubt the two of them are our father’s secret illegitimate children.”

Yun Yiyi fell silent, a troubled look appearing in her eyes.

Ye Anping liked hitting women—and he was her younger brother.

It was… quite a shocking realization for her.

But as shocking as it was, the fact remained.

Immortal law clearly stated that blood relatives within three degrees could not become Dao Companions. If she insisted on marrying Ye Anping, it wouldn’t just harm herself; it would harm him as well.

At this moment, Yun Yiyi could only feel how unfair the heavens were.

She had lived nearly seventy years and finally met a man she truly liked. But this man turned out to be her biological brother.

Biting her lip lightly, she didn’t want to accept it. She argued back:

“The Shadowleaf Sword Art may be a direct-lineage technique, but isn’t it possible that Father taught it to an outsider? Isn’t it a bit too much to establish a blood connection based solely on one sword technique?”

Yun Xi shrugged slightly and pointed to the Snow Qiong of the Myriad Spirits Sword in Pei Lengxue’s hand.

“Then Grandfather’s sword can serve as evidence too, right? Do you think Grandfather would have passed his sword to an outsider? He must have sensed that Pei Lengxue carried the Yun family’s bloodline and entrusted the sword to her.”

“… …”

Yun Yiyi had no rebuttal this time. The bitter expression on her face deepened.

Yun Xi was right. The Snow Qiong of the Myriad Spirits Sword held extraordinary significance for both the Yun family and the Shadowmoon Sword Sect. There was no reason for Immortal Yun Jian to pass it to an outsider.

Seeing Yun Yiyi’s distressed face, Yun Xi quickly tried to comfort her.

“I can tell you really like Ye Anping, but a brother is a brother. Be rational. Weren’t you always the most level-headed one? Don’t let this cloud your judgment.”

“Hmm…”

Yun Yiyi glanced at Yun Xi, exhaled heavily, but couldn’t help harboring more resentment toward her father.

It was all her father’s fault—his unbridled lust had caused everything. He had turned her and her sisters, Yun Xi and Yun Jiujiu, against each other. He had made her lose the one person she had ever loved. He had almost gotten her killed by a sect elder…

Every calamity the Shadowmoon Sword Sect faced had its roots in the messes her father created.

He refused to clean up his own messes and left them for his daughters to deal with instead.

—Damn that father of ours.

Yun Yiyi cursed him inwardly, her clenched fists audibly cracking.

After a long pause, she finally spoke:

“I understand. In a few days, I’ll inform the elders about the Thousand Sword Pool. When the time comes, we’ll go in together and eliminate Yun Kunwu. Let’s set it for seven days from now. How about that?”

“No objections from me.”

“Then I’ll take my leave for now, and Pei Lengxue as well…”

Yun Yiyi nodded to Yun Xi and Pei Lengxue, who was standing a little farther away, and then turned to walk out of the courtyard, mounting her flying sword and leaving.

After watching her leave, Pei Lengxue retracted the Snow Qiong of the Myriad Spirits Sword and walked over to Yun Xi, asking:

“Have you two made up?”

“…I suppose you could say we have.” Yun Xi frowned slightly as she glanced at Pei Lengxue, confusion in her eyes. She asked back:

“Pei Lengxue, why are you so keen on us making up? The issues between me, Yiyi, and the others don’t really concern you.”

“Hmm…” Pei Lengxue pondered for a moment and replied, “Aren’t I also your sister? I don’t want to see my elder sisters fighting.”

“…You’ve known all along that Ye Anping is your biological brother, haven’t you?”

“…Yes.”

“And you still want to marry him?”

Feigning ignorance, Pei Lengxue asked, “Can’t I?”

“Of course not!!” Yun Xi’s frown deepened as she scolded her. “Pei Lengxue, blood relatives can’t—”

Yun Xi placed her hand on Pei Lengxue’s shoulder and naturally began a long lecture on ethics and familial relationships. Pei Lengxue, meanwhile, listened expressionlessly, nodding occasionally in agreement, though her thoughts were clearly elsewhere.

She was wondering—if her senior brother found out that she had helped him, would he praise her? Would he stop seeing her as just a little girl?

<+>

As evening approached, Yun Yiyi flew alone on her sword back toward Jiuquan Peak. The wind rushing against her face felt as sharp and cold as a blade.

Ye Anping is my younger brother. Ye Anping is my younger brother…

The thought repeated endlessly in her mind. The more she dwelled on it, the more indignant and pained she felt. Yet, amidst these feelings, a question lingered.

—Did Ye Anping know he was her brother?

If he did, then why had he taken the initiative to propose marriage? Why hadn’t he told her the truth when they first met?

Lightly biting her lip, Yun Yiyi had the strange sense that Ye Anping knew everything from the very beginning but had deliberately kept it from her. She muttered bitterly,

“Anping, just how much are you hiding from me?”

<+>

By the time Yun Yiyi arrived at Jiuquan Peak, the sun had fully set. The horizon glowed red, heralding the coming night, but Jiuquan Peak was still brightly lit. The training ground was filled with diligent sword sect disciples, hard at practice.

She descended at the gates of Yunjiu Manor, where two Foundation Establishment disciples on guard duty immediately stepped forward to greet her with a bow.

“Greetings, First Young Mistress.”

“Hmm…” Yun Yiyi frowned slightly. “Is Young Master Ye still here?”

“Young Master Ye is in the main hall, drinking and chatting with Second Young Mistress and Young Master Feng.”

“I see.”

Yun Yiyi hesitated as she stepped through the manor gates, pondering how she should face Ye Anping. Yet, a gnawing sense of discontent and longing stirred a dangerous thought in her mind.

Even if she and Ye Anping couldn’t be together in the future, as long as she pretended not to know the truth, then there would be no guilt. It was all her father’s fault for his licentious ways.

She loved Ye Anping too much.

Even after Yun Xi’s words and after spending the journey home reflecting deeply, she still couldn’t completely let go of Ye Anping.

He was the first person she had ever loved in her sixty-plus years of life.

Yun Yiyi felt she was becoming like her mother, who had fallen so hopelessly in love with her father after only a brief time together.

Pausing in her steps, Yun Yiyi let out a bitter laugh and asked herself,

“Yun Yiyi, you’re such a lovesick fool. Such a silly girl. Is he really worth it?”

And then, she answered herself,

“Yes. He really is.”

Closing her eyes, Yun Yiyi let out a deep, heavy breath. Having made up her mind, she clenched her fists tightly and walked toward the main hall.
