"My wish is to awaken the Mangekyō Sharingan," Sasuke Uchiha said without hesitation. Mui looked at him, his eyes flickering, revealing a hint of envy and anticipation. The Box of Ultimate Bliss was last opened during the Sage of Six Paths' era. It was only known to grant any wish, but no one knew how exactly. Giving up the first opening opportunity was certainly a pity. However, being able to verify the Box of Ultimate Bliss's authenticity was also good.
"Mangekyō Sharingan?" Naruto Uzumaki scratched his head, confused.
"It's the ultimate form of the Uchiha clan's bloodline limit, the Sharingan," Minato Namikaze in the sealing space explained. "It possesses infinite power, for example, it can control Kurama."
"Why does Kurama seem so weak?" Naruto Uzumaki blurted out. He had seen Sasame beat Kurama, and he had seen Kushina Uzumaki subdue Kurama. Now he heard that the Mangekyō Sharingan could control Kurama. So, with childlike innocence, he spoke his inner thoughts.
"Bastard!" Kurama was so angry it broke through his defenses, roaring, "This old man is the strongest Tailed Beast!"
"Who are you cursing?" Kushina Uzumaki frowned, glaring at it.
"..." Kurama's powerful aura immediately froze.
"Of course, the Mangekyō Sharingan isn't just about controlling Kurama; it's an all-around improvement," Minato Namikaze, having been Hokage, naturally had read relevant documents, so he gave a few more examples.
"It's actually that powerful?" Naruto Uzumaki looked at Sasuke Uchiha not far away, his eyes showing anticipation. He felt no jealousy towards his teammate becoming stronger; instead, he was happy.
Sasame took this opportunity to bring Mikoto Uchiha over. Upon arriving, she subconsciously tried to call out to Sasuke, but her mouth was covered.
"Don't disturb him," Sasame shook his head.
"Okay," Mikoto Uchiha's body trembled, feeling his breath on her, her face immediately flushing. However, with Sasuke Uchiha right in front of her, she desperately restrained her emotions.
A moment later, a layer of black mist emerged from the Box of Ultimate Bliss, faintly exuding a surging Yin Release power. The side facing Sasuke Uchiha, carved with a smiling face, gradually peeled off, revealing a pitch-black opening. The next second, a powerful airflow spewed from the opening. More precisely, it was malevolent intent, a mixture of various emotions: joy, anger, sorrow, and pleasure. They instantly poured into Sasuke Uchiha's body.
"Ah!" A scream rang out. Sasuke Uchiha's Three-Tomoe Sharingan immediately became tinged with blood. His dōjutsu power rapidly increased, finally reaching its peak. A continuous stream of Yin Release power, like a river, surrounded him. Affected by this aura, Sasuke Uchiha's emotions suddenly went out of control.
"Hahahaha!" He clutched his forehead, letting out a wild laugh.
"Sasuke!" Mikoto Uchiha instinctively stepped forward but suddenly felt her body tremble. Sasuke Uchiha's eyes were no longer Three-Tomoe, but the Mangekyō Sharingan. Did he really awaken it? Her first reaction was that Sasame had indeed been toying with her before. She had given up almost all her dignity and emotions to awaken her Mangekyō Sharingan. And now Sasuke Uchiha just needed to make a wish. But she quickly realized something was wrong.
Something's not right! Sasuke Uchiha's gaze towards her was as if he were looking at a stranger. It was completely different from his usual respect and affection.
"Sasame, what's going on?" Mikoto Uchiha's unease reached its peak. She subconsciously turned to look at Sasame. A hint of resentment also appeared in her eyes. Isn't ruining one person enough? For some reason, she should have been angry, but she couldn't feel any anger at all.
"He absorbed too many emotions, and so a Yin Release monster was born inside him. You just need to punch it out," Sasame explained, half-truth, half-lie. After Sasuke Uchiha made his wish, Satori had already possessed him. His current Mangekyō Sharingan was actually fake. Once Satori left, Sasuke Uchiha's power would revert. Of course, it wasn't a wasted effort. Sasuke Uchiha experiencing the Mangekyō Sharingan beforehand would be quite beneficial for his future. Additionally, Satori leaving didn't mean it was useless. It could act as a battery, continuously providing Yin Release power to Sasuke Uchiha. When the time was right, he would awaken his true Mangekyō Sharingan. Therefore, the immediate priority was to make Satori appear and seal it.
Mikoto Uchiha showed a thoughtful expression. After obtaining her Mangekyō Sharingan, she had a deep understanding of Yin Release. Recalling the airflow that just spewed from the Box of Ultimate Bliss, it had to be said that awakening the eyes was indeed possible. But the danger was high. It was easy to lose oneself.
"Sasuke, control your desires," Mikoto Uchiha took a deep breath and said sternly.
"Mom, I feel more wonderful than ever!" Sasuke Uchiha's lips curved. If he was "cool" before, he was "evil" now. His demeanor had completely changed. Mikoto Uchiha gritted her teeth. It seemed that words alone wouldn't make Sasuke Uchiha sober.
Mangekyō Sharingan activated! A profound and chilling aura emanated from her. From a gentlewoman, she had evolved into a peerless powerhouse.
"How is that possible?" Kushina Uzumaki was stunned. She and Mikoto Uchiha were considered close friends. In her impression, Mikoto was just an ordinary ninja. Completely unrelated to the Mangekyō Sharingan.
"Perhaps it was triggered by the Uchiha clan massacre," Minato Namikaze knew a bit more. In his era, he had fought alongside Uchiha clan ninjas many times. Coupled with the information left by Tobirama Senju, combining the two allowed him to vaguely guess the reason.
"Naruto, you don't need to get involved this time," Minato Namikaze thought for a moment. "Let them, mother and son, handle it. Besides, your teacher is here, so Sasuke will be fine." Although Naruto Uzumaki was worried, he genuinely didn't step forward; instead, he watched from the side.
"Mom, so you also have these eyes," Sasuke Uchiha's expression suddenly became distorted, his eyes showing anger. "If that's the case, why didn't you go for revenge?!" Mikoto Uchiha's body immediately stiffened upon hearing this. A faint sense of guilt actually arose within her. She indeed hadn't sought revenge immediately. Not only that, but she had also grown to enjoy her current life.
"Mom, what have you been doing behind our backs?" Sasuke Uchiha questioned again. Satori possessed the ability to read emotions. But Mikoto Uchiha didn't know this. After being seen through by her own son, her face drastically changed, as if she felt his extreme disappointment, and she stood rooted to the spot. A complex emotion surged in her heart. Mikoto Uchiha subconsciously tilted her head, avoiding his gaze. I... am not a good wife, nor a good mother. At this moment, she wanted to escape.
"Aunt Mikoto," Sasame reminded her at the right time. "Maintain a detached state. The Box of Ultimate Bliss is inherently a conglomerate of emotions; it can see through your emotions." If he didn't remind her soon, he felt Mikoto Uchiha would blurt out their secret. However, there was also a reward. Under this emotional stimulation, her dōjutsu power increased significantly. Mikoto Uchiha heard him, and her eyes violently constricted. So that's it. She blushed with anger, and her hands instantly formed hand seals.
Fire Release: Great Fireball Jutsu! A large amount of chakra rapidly condensed, and in a blink of an eye, a dragon head appeared. The dragon head burned with crimson flames, roaring as it flew out amidst thick smoke. Its body elongated, transforming into a fire dragon, intending to devour Sasuke Uchiha. But it had no effect. Sasuke Uchiha's body suddenly floated in the air, dodging her attack.
Mikoto Uchiha, seeing this, formed a hand seal with one hand and threw shuriken with the other.
Fire Release: Phoenix Sage Fire Technique! Flames enveloped the shuriken, scattering like phoenix flower seeds, blocking all space. Sasuke Uchiha, however, was a beat slower this time. Mikoto Uchiha had gradually entered a detached state. Without excessive emotional changes, he could no longer predict her actions. But even so, Sasuke Uchiha was still powerful enough. He clapped his hands slightly, and immediately a black and red sphere formed, which he then threw. The shuriken, upon contact, instantly turned to ash along with the flames. Mikoto Uchiha's heart trembled. This sphere gave her a very bad feeling. She dodged with the Body Flicker Technique, her crimson Mangekyō Sharingan fixed on Sasuke Uchiha.
Ayanokouji! Her right eye's dōjutsu immediately activated: magnifying fear. But it had no effect. Mikoto Uchiha was stunned. How is that possible? Just then, Sasuke Uchiha appeared before her, kicking without hesitation. Mikoto Uchiha was immediately sent flying backward.
Sasame raised an eyebrow. A filial son indeed. However, this situation was somewhat unexpected. Mikoto Uchiha had too little combat experience, and her two dōjutsu were useless against Satori. Should he intervene?
"No!" Sasuke Uchiha suddenly clutched his head and shouted. Sasame's eyes narrowed. Was he breaking free from Satori's influence because he attacked his mother?
"Aunt Mikoto, use your dōjutsu again to amplify Sasuke's emotions," Sasame said, inspired. In this situation, Sasuke Uchiha and Satori were temporarily separated. This meant there was an opportunity. Mikoto Uchiha heard him and used Ayanokouji without thinking.
"Get out!" Sasuke Uchiha's body trembled even more violently. His face alternated between green and white, showing a struggle. Mikoto Uchiha's right eye shook violently, pouring out all its dōjutsu power.
"Ahhh!" Sasuke Uchiha screamed in pain, his eyes closed. Black airflow enveloped him. In everyone's shocked gazes, a pair of huge black wings extended from his back. The wind howled. The wings soared into the sky, and a monster tens of meters tall filled their vision. It had slender, pitch-black arms and swollen claws. It had no head, but a hideous large mouth and sparse teeth were revealed on its abdomen. After Satori left, Sasuke Uchiha's Mangekyō Sharingan suddenly vanished, and he collapsed. Mikoto Uchiha quickly stepped forward and supported him.
"What is that thing?!" Mui's face showed despair. "Isn't it supposed to grant any wish?!"
