Starting with the Uchiha clan, they began cultivating demonic arts.

Chapter 138 Kushina Uzumaki

With a malicious smile on his face, Uchiha Tou patted Tsunade lightly, signaling her to go and deal with Uzumaki Kushina.

Tsunade blushed slightly, looked up at Kushina Uzumaki, who was pleading, and a hint of guilt flashed in her eyes. She gritted her teeth, reached out, and gently pressed down on Kushina's neck, knocking her down.

A strange chakra flowed into Kushina Uzumaki's body, disrupting the electrical signals within her body and causing her to collapse to the ground.

Seeing that Minato Namikaze had completely lost consciousness and Kushina Uzumaki had also been subdued, Tomokazu Uchiha, not wanting things to get any worse, didn't delay any longer and reached out a hand, placing it directly on Minato's head.

The Devouring Heaven Demon Art was activated in an instant. The chakra in Uchiha Touka's hand vaguely formed a Great Dao Treasure Bottle, which directly drained Namikaze Minato's physical body and chakra, turning him into ashes.

Even after completely draining his physical body, Uchiha Touyu did not spare his soul. With a wave of his hand, he activated his Soul Binding ability and directly summoned the soul of Namikaze Minato.

Putting aside other things, Uchiha Touyu was extremely envious of the Flying Thunder God Technique modified by Minato Namikaze. The variations of the Flying Thunder God Technique, such as the lightning guide, were also incredibly versatile, and it could be said that they had completely mastered the art of manipulating space.

Furthermore, Minato Namikaze himself also possessed Sage Mode skills, and his techniques were extremely advanced. If it weren't for the limitations imposed by his chakra, his Sage Mode level would definitely surpass Jiraiya's.

Although Uchiha Touyu had long since mastered Sage Mode, he could learn from the strengths of other regions and find that the native Sage Mode of the ninja world was beneficial to him.

"Minato... Waaaaah... Minato! I'll fight you to the death!"

"You bastard, you demon, I will kill you!"

Kushina Uzumaki, who was being held down by Tsunade, struggled desperately even though she was completely limp, and looked angrily at Touya Uchiha.

Uchiha Tou walked up to Uzumaki Kushina, grabbed her chin, lifted her head, and gave her a standard villainous smile, almost bursting into laughter.

"Don't rush me. Tsunade said the same thing to you back then, and look at her now, she's quite obedient, isn't she?"

"Soon, you will become one of my most loyal subordinates, just like her."

Kushina Uzumaki's body trembled slightly as she recalled Tsunade's obedient demeanor under Touya Uchiha. A chill ran down her spine, and her body began to tremble involuntarily.

"Gulp... Just kill me!"

"Heh, dying isn't that easy. And... don't you want your child anymore? That child's name should be Naruto, right?"

"Naruto! What are you doing to Naruto? He's just a baby!"

"That depends on whether you listen to me or not, ma'am. You wouldn't want anything to happen to your child, would you?"

"Ugh...Despicable and shameless..."

At this moment, Kushina was swaying precariously, her face filled with despair. But just then, Tsunade spoke hesitantly:

"Hiyu, Kushina just gave birth, she needs at least some time to recover..."

Uchiha Touyu waved his hand and chuckled, "Don't worry, I'm not that impatient."

"She's not in good health right now, so we won't need to use your methods. I've been studying the Joyful Union Manual recently and have mastered a new technique; I'll use that to control her!"

"Damn it... Don't try to control me! Tsunade, wake up! He already said you've been controlled by him all along!"

Tsunade remained calm upon hearing this and said softly:

"I already knew about this, but I was born to be Fei Yu's ninja weapon, and I can't live without him anymore. It's his freedom to use me however he wants."

"Don't worry, Kushina, you'll soon become like me, and then you'll find that being a ninja weapon is much more enjoyable than being a female ninja..."

"Tsunade... what nonsense are you talking about... how could anyone like being a ninja weapon..."

Kushina Uzumaki trembled even more violently. The thought that she might end up like Tsunade made her wish she could just die. But at that moment, Touma Uchiha grabbed her hair and forced her to look into his eyes.

Kushina Uzumaki, of course, knew the power of Tobi Uchiha's Sharingan, and quickly closed her eyes. But just then, she heard the cry of a baby.

"Naruto! What are you going to do to Naruto?!"

In her anxiety, Kushina Uzumaki had no choice but to open her eyes. The moment she opened her eyes, the three tomoe in Touya Uchiha's eyes spun, and she immediately activated the Tsukuyomi technique.

In an instant, Kushina Uzumaki found herself lying on a luxurious bed, her limbs bound by ropes, her body spread out in a starfish shape.

"What... what's going on here?"

"This is the Tsukuyomi world. With my current eye power, I can probably maintain this world for two or three years..."

"The Divine Intercourse Technique in the Joyful Union Manual originally required both parties to cultivate to the point of divine will fusion. However, I have combined it with the Tsukuyomi Illusion Technique, which allows me to forcibly perform this Divine Intercourse."

"Compared to the kind of control technique that involves direct physical contact, the technique of spiritual communication is much more effective. Don't even mention two or three years, just two or three days and you will be willing to become my ninja weapon."

"No, no, let me go! Let me go! You bastard, pervert, lecher!"

Although Kushina Uzumaki didn't know what the Divine Communication Technique was, she knew what was going to happen next, and immediately began to struggle with all her might.

However, she was already under Uchiha Touyu's Tsukuyomi genjutsu, so this struggle was of no use to Uchiha Touyu except to add a little fun.

Time flew by in the illusion, and when Kushina Uzumaki returned to reality, she trembled violently, arched her back, and let out a scream:

"Eeeeeeeeoo ...

Her once pretty face was now completely ruined; her rosy tongue protruded, her mouth was wide open, her eyes rolled upwards, and her lower body was utterly soaked, her clothes and pants completely drenched.

Uchiha Touya, who had also finished casting his genjutsu, was still full of energy. He waved his hand and said with a hint of disdain:

"Tsk, she still lost control of her bladder... Oh well, Tsunade, once Kushina recovers, let her put on a show for you!"

"I believe that with this, the position of Hokage will truly belong to you."

Despite the Third Hokage's seemingly reluctant acceptance of the position in the original story, and his apparent desire to hand it over to Jiraiya, no one truly knows whether the Third Hokage genuinely wanted to relinquish the Hokage title.

In any case, Uchiha Tou was overly cautious. Once his plan was completely completed and Tsunade had made contributions, even if the old man wanted to rise to power again, it would be a complete waste of his time.

Tsunade nodded, gently stroking Kushina Uzumaki. Medical chakra, emitting a faint green light, was channeled into Kushina's body, quickly calming her down.

Kushina Uzumaki opened her dazed eyes, regained her senses, and looked around with some confusion. When she saw Tou Uchiha, her eyes immediately filled with infatuation.

"Flying Feathers~~"

At this moment, under Tsunade's medical chakra, Kushina Uzumaki's previously controlled nerves had long since recovered. She stood up and wanted to rush into Touma Uchiha's arms, but when she saw the look of disgust on Touma Uchiha's face, she stopped herself.

"Go change your clothes first, don't you feel cold?"

Upon hearing Uchiha Tou's words, Uzumaki Kushina also felt the chill on her lower body clothing, which felt cold and sticky to her legs, making her quite uncomfortable.

Most importantly, she also smelled a strong odor of urine, which immediately made her face turn red and she felt extremely embarrassed.

Uchiha Hiyu opened the Kamui dimension, and the portal led directly to his room, where Tsunade took Kushina inside to change her clothes.

Kushina was quite curious after entering the Kamui dimension. After changing her clothes and wiping her body, she looked around and then saw a familiar large bed. A blush rose on her face.

"So, Kushina? Are you willing to become Tobi's ninja weapon now?"

Seeing Kushina's expression, Tsunade asked with a grin, making Kushina a little embarrassed:

"Tsunade-neechan, please stop... I understand how you feel now. Even though I know perfectly well that I'm being controlled by Hiyu, I can't live without him anymore..."

Since the Hehuan Manual can be included in the book of demonic inheritance, it is naturally not a proper dual cultivation technique. Once one becomes a vessel, one's body and mind will be completely controlled by the master. The longer the cultivation time, the more times, and the greater the difference in strength, the more profound this control will become.

In particular, Uchiha Touyu, through the Tsukuyomi genjutsu, also developed the spiritual intercourse technique from the Hehuan Treasure Manual. In any dual cultivation technique, the spiritual intercourse technique is a higher level than physical intercourse, and the effects it brings are naturally more intense.

Therefore, Kushina Uzumaki's current obsession and obedience to Touya Uchiha even surpasses that of Tsunade.

Just as the two women were chatting, they suddenly heard a baby crying next to them. Kushina Uzumaki was slightly taken aback, pushed open the door, and saw Shizune comforting the baby in her arms.

Looking at the baby Naruto before her, Kushina Uzumaki's eyes became complicated. After a long while, she sighed, turned around, and walked out of the Kamui dimension.

Kushina Uzumaki, having just stepped out of the Kamui dimension, saw Tobi Uchiha standing in front of the dimension's gate. The gloomy look on her face immediately vanished, and she happily hugged Tobi Uchiha's arm.

Uchiha Touyu reached out and gently stroked Uzumaki Kushina's hair. Seeing this beautiful widow, who had originally wanted to bite her tongue and commit suicide, become obedient and completely subservient to him, Uchiha Touyu couldn't help but marvel at the power of the Joyful Union Manual.

"It seems that sometimes, offering black energy directly as a sacrifice might yield even better results than a precise sacrifice..."

In the present world, apart from some dead people, half-dead people, and sealed individuals, Uchiha Tou has truly no rivals, so he is not in a hurry to obtain more and stronger inheritances.

Instead, you could try a rough version of the sacrifice; you might get some useful items.

Uchiha Touyu had actually conducted some experiments before, using hundreds of black wisps to perform a crude version of sacrifice in ten separate instances, but what he got in return was...

What about the Demonic Disintegration Technique that kills upon use, the zombie-making art that can't find Yin Meridians or Dragon Lairs, the Thousand Spider Venomous Hand that disfigures the practitioner, and the Rakshasa Divine Art that prevents one from living past 27—it's still an incomplete version because of insufficient black energy...

After all, most so-called demonic inheritances have some side effects. As for demonic inheritances without side effects, they are either extremely expensive or extremely difficult or dangerous to cultivate.

Even though Uchiha Touyu made rapid progress in the early stages of the inheritance he obtained through precise sacrifice, he still encountered many bottlenecks in the later stages.

To overcome these difficulties, one either needs an unwavering character, exceptional talent, and incredible luck—a true genius—or one must build a foundation of immense strength through countless deaths and sacrifices to forcefully break through.

These thoughts flashed through Uchiha Touyu's mind for only a moment before he looked at Uzumaki Kushina:

"Kushina, now you know what you should be doing, right?"

Kushina, who was rubbing against Uchiha Touyu like a cat, nodded after hearing the question and said:

"Isn't it just about controlling the Nine-Tails to attack Konoha and letting Tsunade do a great job? Don't worry, after my spiritual communion with you, Touya, my strength has improved a lot, and I can completely control the tailed beast inside me!"

The stronger Uchiha Tou's master is, the more benefits each dual cultivation session will bring to his vessel. Moreover, this dual cultivation session is extremely special.

Even though Kushina Uzumaki's primordial yin energy had long been broken, her first dual cultivation, especially one that involved a long period of spiritual intercourse, still caused a significant leap in her strength. Her chakra nearly doubled, and the Sage Body of the Uzumaki clan began to awaken, allowing her to directly sense natural energy.

In this situation, Kushina Uzumaki's control over Kurama naturally increased significantly. Before reaching an agreement with Kurama, she was unable to awaken the perfect Jinchuriki, but she could forcibly use Kurama's chakra and transform into a complete tailed beast without any pressure.

Yes, Uchiha Tou's plan was simple: Uzumaki Kushina would transform into a fully-formed tailed beast and go to destroy Konoha, then Tsunade would stop her, and finally he would become the hero who saved Konoha and ascend to the position of Hokage.

As for Tsunade's strength, how could she possibly suppress a fully-formed tailed beast? You must know that Tsunade and Uchiha Tou's dual training during this period was not in vain, and her strength is now vastly different from what it used to be.
