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

The mist encircled the peaks, and birds chirped melodiously.

Inside the carved window of a pavilion’s overhanging eaves, a small golden figure stood atop a wooden box, raised to the height of the desk, wielding a brush to write with great effort.

Beside her, a tall maid sighed quietly:

“Ah—Miss Jiujiu, may I suggest that you stop writing this love letter? You’ve never touched a brush before, even your grip is wrong, and you’ve already wasted over twenty sheets…”

Yun Jiujiu pursed her lips in annoyance, glancing at the crumpled balls of paper littering the ground.

“You don’t understand a thing! This is my heartfelt intention, do you hear me? Heartfelt intention! Brother Yu will be absolutely thrilled when he gets it.”

The maid gave the latest letter—its red ink resembling dripping blood—a dubious glance and murmured, “But I feel like it exudes murderous intent… as if you’re planning to dismember Young Master Feng and eat him…”

“… …”

Yun Jiujiu froze for a moment, then turned back to reread the letter she had been rather satisfied with:

“I love your heart, I love your guts, I love your liver, I love your face, I love all of you. I want to marry you, promise me a bond of three lifetimes, and let us be together forever, okay? ❤❤❤~”

“I think it’s great.”

“…If you say so, Miss Jiujiu,” the maid muttered, seemingly giving up on arguing. She shook her head with another sigh. “It’s well-written.”

“Good, then find me a pretty envelope to seal it in. Also, fetch the chicken-slaughtering knife made of Xiuling Jade from the storeroom, tie it with a red ribbon, and I’ll deliver them together later.”

?

“Huh? A chicken-slaughtering knife?”

“Yeah! Brother Yu likes roasted chicken, so a chicken-slaughtering knife is perfect. I remember there’s one in the storeroom…”

“…If you insist, Miss Jiujiu. I’ll fetch it for you.”

<+>

Meanwhile, above a pavilion in Yun Jiu’s residence.

Dressed in a scholar’s robe, Feng Yudie lounged atop the roof, her legs dangling and a blade of foxtail grass hanging from her mouth.

Her silver hair shimmered under the morning light.

Despite the rare pleasant weather—a welcome change from the usual snow or drizzle in Shadowmoon Sword Sect—Feng Yudie’s brows remained furrowed.

Part of her distress stemmed from not being able to see junior sister Pei. The other part was due to an unbidden memory of being carried by Ye Anping in a bridal carry during their infiltration mission a few days ago.

In her 17 years of life, that was the first time a man had ever held her like that.

If she had to describe the feeling…

—Not bad.

At least, it wasn’t as unpleasant as her master had once described.

Feng Yudie vividly recalled her master’s warnings during her childhood: men’s chests were as hard as steel plates, and being held by one felt like sitting on a tiger bench—utterly uncomfortable.

Unable to imagine it back then and driven by childhood curiosity, she had once wanted to find a man to carry her just to see if it was true.

Her master, the True Immortal Tai Xu, responded by buying an actual tiger bench and making her sit on it for an entire afternoon.

The experience left a deep impression on her, equating “being carried by a man” with “sitting on a tiger bench.”

However…

When Ye Anping carried her the other day, it didn’t feel anything like sitting on a tiger bench. Compared to being carried by her master in the past, his arms were steadier, and there wasn’t the uncomfortable sensation of two lumps pressing into her waist.

—Could it be that her master had lied to her?

True Immortal Tai Xu was the most important person in Feng Yudie’s life—the one who had raised her since childhood, acting as both father and mother.

No matter what, she would never doubt her master.

So now, she was left questioning…

“Xiaotian, Xiaotian~”

『What now?』 Xiaotian, holding a small stonemason’s hammer, poked half its body out from Feng Yudie’s forehead, looking around warily. 『There’s no one around. Why are you calling me? Didn’t I tell you I’m busy these days? Don’t call me unless it’s urgent.』

Feng Yudie remained silent for a while.

Xiaotian had indeed been scarce lately.

In the past, it would even come out and nap on her stomach while she slept.

“I’ve been meaning to ask—what have you been so busy with?”

『I’m straightening your meridians. Don’t worry about it… it’s good for you.』

Feng Yudie frowned slightly, her gaze falling on the small chisel in Xiaotian’s hand.

“With that?”

『Yep.』 Xiaotian grinned. 『Actually, you could ask Ye Anping to help. It’s similar to his therapy technique. He’s probably more skilled at it. Why don’t you ask him sometime?』

“Maybe later.” Feng Yudie pouted, then suddenly asked, “Hey, Xiaotian, do you think Young Master Ye might actually be a girl disguised as a boy?”

？

Xiaotian tilted its head, clearly baffled. 『Huh?』

“It’s just… he doesn’t have any of that manly aura, and he smells nice. Though, I’ll admit Junior Sister Pei smells even better.”

At that, Xiaotian broke into a sly grin, squinting its eyes mischievously.

『Yudie, Ye Anping is definitely not a girl in disguise. I’ve seen his man side myself.』 It returned the chisel to her forehead and floated out, raising a finger. 『What’s happening here is simple—you’re attracted to him.』

“Attracted?”

『Exactly! Attracted. In other words, whether you realize it or not, you’re already falling in love with him. This is love, Yudie. Love is mutual attraction and trust. It’s time you face your feelings.』

Feng Yudie furrowed her brow. “So you’re saying Young Master Ye tricked me?”

？

『…What?』

“Hmm…” Feng Yudie sat up, resting her chin on her hand as she pondered. “My master did say that men are particularly good at deceiving women. Many girls unknowingly get tricked into following men, and by the time they realize it, it’s already too late.”

『… …』

“Could it be that Young Master Ye is just as cunning? To think I trusted him so much. Luckily, I figured it out. Ha! He thought he could fool me.”

Xiaotian’s mouth fell open slightly, a tinge of regret washing over it.

It had merely wanted to nudge its Yudie and Ye Anping together. How did things backfire so spectacularly?

『Yudie… I didn’t mean that Ye Anping is tricking you. He’s genuinely good to you.』

“Well, yes, he has been kind to me. But my master also said that men deceive women by first treating them well, gaining their trust, and then leaving once they’ve gotten what they wanted.”

『… …』

“When you think about it, it all lines up. He’s so skilled at it! He even directed me to earn Yun Jiujiu’s trust, and once we got what we needed, he told me to leave her behind.”

『But… but!』 Xiaotian protested. 『That’s different! Ye Anping deceived the Yun family for the sake of the Shadowmoon Sword Sect. It was for a good cause! A kind lie!』

Feng Yudie pouted. “It’s still a lie. Lying makes you a bad person. My master wasn’t wrong—he’s just like any other man: bad news.”

『Ah…』 Xiaotian dared not say another word, fearing it might worsen the situation.

Left to her own devices, Feng Yudie’s thoughts spiraled out of control. Explaining anything to her now seemed nearly impossible, especially since Ye Anping hadn’t yet reached the pedestal of reverence her master occupied in her heart.

It seemed that the only way Ye Anping and Feng Yudie would ever get closer was if he could somehow surpass her master in her eyes. But when would that ever happen?

Xiaotian gazed forlornly at the sun, letting out a long sigh:

『Sigh—』

“Do you think Junior Sister Pei got tricked by him too?” Feng Yudie pouted, lying back down and resting her hands behind her head. “Just like the person who once deceived my master.”

Her thoughts drifted to the portrait hanging in her master’s chambers.

Whenever her master looked at that painting, there was always a trace of sorrow in her expression, sometimes even anger. Occasionally, she’d stab the painting with her sword.

Feng Yudie had asked about it before, but her master never said much, only revealing that the person in the painting was the man who had once stolen her heart.

Feng Yudie didn’t know his name or which sect he came from. All she knew was the tattoo of a twin-petaled cherry blossom on his brow.

Though her master never gave any instructions, Feng Yudie had vowed to herself that if she ever met that man, she’d chop him down without hesitation!

“Phew—”

Closing her eyes, Feng Yudie decided to let go of her bothersome thoughts and simply enjoy the sunlight.

But just as she was beginning to relax, a sharp, irritated voice shattered the stillness below the pavilion.

—“Brother Yu! Why are you up on the roof again~?”

“… …”

Six imaginary dots floated above Feng Yudie’s head. With a resigned pout, she guessed Yun Jiujiu was probably here to challenge her to a spar again.

At first, sparring with Yun Jiujiu had been fun, but after winning so many times, it had become tiresome. Yun Jiujiu was weak yet persistent. She’d barely recovered from her last injury and was already back for more.

After a moment’s hesitation, Feng Yudie leaped down from the roof to meet her.

“Jiujiu, what is it now? If it’s another fight, let’s skip it today. You just woke up last night. Rest a bit, will you?”

As Feng Yudie landed in front of her, Yun Jiujiu pressed her lips together shyly, a rather uncharacteristic gesture for her. She clasped her hands behind her back, swaying slightly.

She was dressed in a newly made glaze-colored gown, her hair cascading in soft waves over her shoulders, and her cheeks faintly dusted with rouge.

“I’m not here to fight today.”

“Then what is it?”

“I came to thank you for saving me, and also…”

Yun Jiujiu averted her gaze, then pulled out a chicken-slaughtering knife and a letter from behind her back. The jade-like blade’s tip was pointed directly at Feng Yudie’s chest.

“Here.”

“… …”
