Your sister-in-law knows all sorts of special tricks

After time travel, Kyosuke returned to his Family for the first time.

He was only seven years old at the time, and apart from his talent, he was basically useless.

No one would have guessed that such a young child would already be thinking about the future.

Uchiha Chō a year older than him and was a war orphan with a tragic life, someone you could see everywhere.

By chance, the two met on the battlefield.

The boy rescued the girl and taught her the skills she needed to survive.

In return, the girl offered to serve him for life, but was rejected by the boy, Kyosuke.

"I don't need women, I need helpers who can solve my problems."

From that day on, Uchiha Chō became his Secret Shinobi, and Kyosuke's deepest hidden shadow.

Once Uchiha Kei's talent was confirmed, Cho began her eight-year career as a spy.

She needs to make her target fall in love with her, to be hopelessly infatuated, only then can she meet the conditions for unlocking the Mangekyō.

At the same time, she was unwilling to live her life as Kyosuke's shadow.

Even without any hope, she still wished to stand beside an adult; this was the most humble wish in a young girl's heart.

So the two made an agreement that Butterfly must devote herself wholeheartedly to the relationship.

Not only does she need to make her target fall in love with her, she also needs to give genuine feelings in return.

The final chapter of the plan will be her personally ending Uchiha Kei's life.

If she can activate the Mangekyō, then Butterfly can shed her identity as a shadow and walk in the shadows to truly reach Kyosuke's side and walk alongside him.

If that doesn't work, then he will have to remain in hiding for another ten years before he can gain his freedom.

Recalling his past with the girl, Kyosuke leaned against the tree trunk, his face as always filled with a smile.

To ensure absolute success, Uchiha Chō indeed die at the hands of her target.

While the two were fighting, a hidden Secret Shinobi secretly took the body away and delivered it to the "Afterlife".

The Afterlife are a secret squad assembled by Kyosuke. These people are all thoroughly brainwashed assassins, and even Maya is unaware of their existence.

The team members do not need to fight, nor do they need to conduct espionage.

Their sole purpose is to unleash a Forbidden Technique secretly developed by Sunagakure at crucial moments...

Creation Rebirth!

The Creation Rebirth involves using all of one's own Chakra as a medium to infuse life force into the deceased, thereby achieving the goal of reviving them.

In Gale, Chiyo of Sunagakure used this technique to bring back Gaara had lost the One-Tail Shukaku.

Of course, the Creation Rebirth can also be used on living people, and it has a significant effect on restoring Chakra and healing injuries.

Kyosuke had gone to great lengths to develop the Afterlife Squad, and today's first operation had resurrected a valuable subordinate for him.

"Now, it remains to be seen whether she can pass the final test."

The young man was still smiling, but a hint of coldness flickered in his eyes.

Uchiha Chō's talent is astonishing, and her temperament is exceptionally strong. If possible, Kyosuke would never want to lose such an excellent helper.

After years of infiltration, it's fair to say she developed very genuine feelings for her target.

By personally killing her husband, she will surely be able to awaken the Mangekyō Sharingan.

However, water can carry a boat, but it can also capsize it; Kyosuke will not tolerate any disloyalty from his subordinates.

If the butterfly were to truly succumb to despair, he would have no choice but to personally send her away, allowing the star-crossed lovers to meet again in the afterlife.

Don't call him cold-blooded; that's just how the game is played.

Someone will always have the last laugh, and Kyosuke hopes that person will always be himself.

"I will not let tears of pity fall on my dead body."

Never!

A short while later, heavy footsteps suddenly came from behind.

Kyosuke did not turn back, even though he knew that the girl's heart must be in turmoil at that moment.

Nevertheless, he kept his back to the other person the entire time, a behavior that can be described as extremely dangerous.

Even though "Finality" could save his life, he didn't know what kind of Dojutsu the girl had awakened.

If it's a powerful offensive ability, Finality might not be able to protect him completely.

He was giving the girl a chance, a chance to kill herself.

Normally it would be one thing, but in this state, if someone truly had murderous intent, no one could suppress it.

Soon, the footsteps drew closer and eventually stopped about a meter behind him.

Neither side spoke, and an eerie, heavy atmosphere lingered between them. The faint but palpable killing intent caused the Secret Shinobi watching from afar to grip their Kunai.

Staring at the young man's back, Uchiha Chō struggled to suppress the murderous intent surging within her, trying to break free from years of emotional pretense.

"It's all fake, it's all fake..."

"You are everything to me, and that will never change, no matter how much time passes."

Five minutes passed, and the butterfly, who had been suppressing her emotions for so long, suddenly began to breathe heavily.

Her clothes were soaked with sweat, outlining her perfect, breathtaking curves.

"Sir~"

"I'm ready now~"

"Don't say things that are so easily misunderstood." Kyosuke turned around, his face beaming with a bright smile.

He helped her up from the ground, and as their eyes met, they both tacitly ignored what had just happened.

"What ability did you awaken?" Kyosuke, quite curious.

"You mean it?" Reaching out to stroke her eyes, Uchiha Chō's lips curved into a captivating smile. "I've learned quite a few abilities, you know~"

"We're having dinner at my sister-in-law's tonight, and she's showing off everything to the adults!"

"... Alright, alright." Kyosuke rolled his eyes, trying to calm his wildly beating heart.

The little girl used to always try to seduce him, but back then she was young, and bean sprouts couldn't arouse his interest at all.

Things are different now. In terms of size alone, Butterfly is almost a Number One version of Tsunade.

Not to mention, she herself is particularly knowledgeable, understanding the power of verbal flirting, calling me "sister-in-law" one moment and "widow" the next.

If it weren't for his exceptional willpower, Kyosuke might have actually gone to his sister-in-law's house to study that night.

"My apologies, my apologies."

After laughing and joking for a while, the two headed towards their Family's home together.

Now that I've got my cousin's Mangekyō, the next crucial step is changing his eyes.

To unlock the Eternal Mangekyo, simply swapping eyes is not enough.

He needs to absorb Uchiha Kei's eye power and continuously raise the upper limit of his eye power through fusion. The closer their blood relationship, the higher the success rate of unlocking the Eternal Eye.

This process is irreversible; once the fusion begins, the eyes he removed are essentially useless.

This is the curse deeply etched into the bloodline of the Uchiha.

"By the way, don't have a relapse when you get back to the Family, or Mito will beat you to death."

"Sister-in-law understands, don't just sneak into the house and shout, I understand, I understand~"

"Shut up..."
