As soon as Xuehui stepped through the door, Zohara Mu noticed a pale white star-like point appearing above her head. However, it wasn't until he stared for a while that corresponding text began to appear on the blank panel in front of him. Clearly, this was the channel for acquiring "Heart Knot Points"! As his consciousness deepened, the detailed content immediately unfolded.

"Zohara Friend Book"

"Zohara Xuehui's Heart Knot (Shallow)"

"Details: Recently, it seems like Mu is hiding something from me...?"

Almost the instant he saw this detail, Zohara Mu, who had been immersed in the thrill of finally discovering the method to use the cheat, suddenly tensed up. The smile that had seemed natural began to slowly fade away, and his facial muscles softened slightly. Years of experience in lurking made him immediately think of the most dangerous possibility.

‘Am I being suspected?’

In that moment, a strong desire to survive and his instincts as an undercover agent prompted him to think quickly, digging through what he might have inadvertently revealed recently, even to someone as inexperienced as Xuehui. However, no matter how much he searched, it seemed he couldn’t find where he had gone wrong. The more he thought about it, the more uneasy he became, and cold sweat began to break out on his back.

How could this happen?

Have I been so lax lately?

Could others have also sensed something?

Has the Anbu already set their sights on me?

Zohara Mu's heart began to beat slower, and various contingency plans flitted through his mind at lightning speed, tracing back through possibilities and escape routes. Until Xuehui called out to him, somewhat puzzled:

"Onisan?"

It was then that he suddenly came to his senses. Before he could speak, Zohara Xuehui had already tiptoed and reached out to touch his forehead, asking in confusion, "Did you overdo it with refining chakra just now? Your face is as white as snow, and your temperature is icy?"

"Um, you’re not catching a cold, are you?"

The girl grew even more worried about his condition. Zohara Mu quickly stabilized his mindset, allowing her small hand to roam over his face as he casually replied, "Don't worry, I'm fine. A good sleep will restore me completely."

"That's good," Xuehui said with a smile. "Besides, you can't practice right now anyway, so come down for dinner! The sukiyaki is almost wasted."

"Speaking of which..."

Zohara Mu's voice paused slightly as his azure eyes fixed intently on the girl before him, and he calmly stated, "Xue-chan, you should still have something to tell me, right?"

"Uh?"

Zohara Xuehui was momentarily taken aback upon hearing this.

Looking at his 'sister' who appeared somewhat dazed, Zohara Mu tried to soften his tone, obscuring all specific references in his words to steer the conversation: "Actually, I noticed this some time ago. Even you, Xuehui, must be troubled by knowing about this, right? Or perhaps feeling at a loss?"

"..."

At these words, Zohara Xuehui was stunned.

Raising her head, she saw Zohara Mu's piercing gaze fixed firmly on her, causing her to slightly avert her eyes. Noticing the girl's small movement, Zohara Mu couldn't help but feel his heart tighten and sighed silently.

No one is a sage.

Even raising a puppy for a few years can create feelings, let alone a living person. Even though Zohara Mu had made countless contingency plans for exposure over the past ten years of fear and anxiety, when that day truly arrived, he still felt caught off guard.

In any case, he would first attempt to persuade her. If that didn't work, he would quickly subdue her and tie her up at home to buy time. If he couldn't escape...

In an almost fleeting thought, horrifying scenes of himself facing thirty-six types of whips, seventy-two forms of torture, and one hundred and eight methods of interrogation flashed through his mind.

Gulp.

Just as Zohara Mu braced himself for the worst, Zohara Xuehui, with her lips pressed together, suddenly spoke softly:

"Mu, you must have your own difficulties as well. Is it for money? Or are you being forced?"

"..."

"In fact, I also accidentally discovered it... when Mu was meeting that person."

Zohara Xuehui's voice grew quieter, but the tone still carried an unmistakable tremor as she struggled to contain herself.

Zohara Mu’s mind suddenly flashed back to the scene earlier in the day when his shadow clone met with Yuzuki Yagura on the rooftop.

Damn it, it shouldn't be!

He had checked thoroughly.

Even as he tried to suppress it, his heart raced faster, his tone slowed, yet his whole body felt like a tightly wound spring, ready to spring forth at any moment.

"That person?"

"That's right!"

Zohara Xuehui suddenly raised her head, her voice filled with indignation:

"That seemingly wealthy Uchiha woman!"

Like waiting for a judgment, Zohara Mu felt his old waist suddenly sway at the moment the girl spoke.

"Huh?"

"You're still pretending! I saw everything!" Zohara Xuehui pressed on, her small face tense like a housewife who caught her cheating husband, exasperated. "Mu, the other night after work, you met with a long-haired, very beautiful Uchiha woman, right?!"

"You cheating scoundrel!"

"And Mu! You actually secretly found a girlfriend, even though we promised when we were kids that we would get married when we grew up."

"Though I understand Mu is about that age now..."

"..."

Zohara Mu listened quietly to Xuehui's incessant chatter, his mind gradually blanking out.

He suddenly transitioned from extreme tension to complete relaxation, as if he had been pricked by a needle, deflating completely.

Pff!

As for who that Uchiha woman Xuehui was talking about was, he couldn't recall at all, but it didn't matter anymore.

At that moment, he suddenly felt a wave of relief.

Zohara Xuehui was a lovesick fool, and that was great.

However, aside from his jumping sister, his newly activated Tsukuyomi also began to spout nonsense.

"Kuyashi~! (So unfair!)"

"You clearly promised to live together forever, and now you have another woman outside... this is intolerable!"

"As both a childhood friend and a destined wife, Zohara Xuehui will fight with absolute determination!"

"Hey! That woman brought her brother to his knees; she must force him to come back to me!"

"Mu belongs to Xuehui alone, okay♡"

Tsukuyomi was excited to the point of losing her composure, her tone becoming manic, spewing one outrageous statement after another, as if all her computing power was directed towards a strange direction, devoid of any sense of moderation.

Zohara Mu gradually regained his calm, facing the furious Xuehui with a somewhat helpless demeanor:

"Not at all."

Zohara Xuehui still maintained a stern expression, warily declaring, "I don't believe it! A few days ago, Mu got home so late and insisted on going to the training ground to practice ninjutsu... that clearly indicates you were out on a date!"

Zohara Mu's expression paused for a moment.

To deal with the last boss who forced him to work, he had indeed spent a considerable amount of time, and it was only expected that people around him would notice.

However, he never thought it would be pointed out from this angle.

But it wasn’t that there wasn’t a solution.

With the cheat activated... he could finally be a bit bolder than before in many situations.

"Since Xuehui says so, then let me show you a bit of the fruits of your big brother's training!" Zohara Mu placed his hands on his hips, suddenly adopting a rather smug expression.

"Huh?" Zohara Xuehui looked skeptical, "Mu, besides a few water-style techniques at home, have you learned any other ninjutsu?"

"Exactly."

Zohara Mu said, raising one hand towards Xuehui.

"Hey!"

Initially, Zohara Xuehui thought her brother was just being vain, boasting a little.

However, before she could look away, she saw Zohara Mu's eyes suddenly sparkle with a brilliant light, shimmering like stars.

The next moment.

"Vroom—"

A spiral of chakra suddenly surged from the center of the young man's palm, rapidly spinning and gathering toward the center, swaying until it finally formed a perfect sphere of chakra.

The air whipped up as the mass of chakra surged, creating waves in the narrow room, tousling the girl’s hair and the hem of her soft skirt.

Everything in the room seemed to resonate with the rotation of this small sphere.

The curtains fluttered.

However, the girl seemed completely oblivious to everything around her, her azure eyes fixated on the chakra sphere in Zohara Mu's palm, unable to look away.

Even though she had only just graduated as a lower ninja, Zohara Xuehui immediately recognized the difficulty of developing this unmarked ninjutsu, as well as the terrifying destructive power hidden within this chakra.

An unprecedented advanced ninjutsu?!

Almost instinctively, Zohara Xuehui eagerly asked:

"Mu!"

"What is the name of this technique?"

Zohara Mu, mimicking the tone of the majority of ordinary young people in Konoha, spoke with a relaxed voice tinged with a hint of pride, smiling as he replied:

"This technique is called... Rasengan."

"It’s a powerful ninjutsu developed by a super genius."

Zohara Xuehui gazed at this unprecedented technique and finally believed all of Mu's previous claims.

It is well known that the development cycle for ninjutsu typically spans years.

Since that was the case, all previous doubts naturally became nonsense.

Until this moment, the girl finally felt completely at ease, her azure eyes revealing uncontainable excitement as she looked up at her brother, exclaiming:

"Mu! I want this!"

Zohara Mu's smile remained warm:

"You want to learn? I can teach you."

The instant his words fell, the corresponding prompt appeared on the previously blank panel.

"Zohara Xuehui's Shallow Heart Knot (Completed)"

"Heart Knot Points +1"

"Zohara Friend Book: Collecting Character 'Zohara Xuehui'"

"Bond Level Increased ↑"

"Zohara Xuehui Bond Level: Three → Four"

At the moment he saw this prompt, Zohara Mu's previously tense heart finally relaxed.

For a transmigrator, as long as there is a cheat, what is there to worry about?

Having descended into this world for a full fifteen years, he finally had a thread of reliance in his heart.

...

Once the system panel closed automatically, Zohara Mu didn’t notice—or rather, couldn’t notice—that on the panel, which was completely closed, different path options quietly appeared, quickly sliding past like a waterfall of data.

"Final Bond Path 1: The Entrance Battle"

"Mu, you said you'd love me forever, right? Because Onisan is a treasure that belongs only to me... so, I will give everything to you too."

"Final Bond Path 2: The Rooftop"

"Hey, Onisan. You saw everything, right? This inexplicable person suddenly, suddenly starts talking about having a child... Look! Her belly, isn’t it completely empty?"

"Mu? Why are you looking at me like that?"

"Final Bond Path 3: Corpse and Snake"

"If from today onward, you transform into a snake, driving away poison and devouring people, using seductive words to tempt the hearts of mortals, making them willingly become your nourishment. But, as you turn, still with that mouth that devours blood, you roar out 'Love me,' then... can I respond to your voice? Is this heavy love sincere enough?"

"When? Why did I become an undercover agent? Why... especially Mu?"

"Forget it, with my brother dead, I no longer care to distinguish between rights and wrongs; someone must pay for something... don't walk too fast, wait for me below, Mu."

"Final Bond Path 4: ..."

"World Line Undetermined"

"Bond Calculation Continuing..."
