Tsunade expressed her doubts.
Chapter 79: Terrifying Advancement
"Ding! Congratulations, Master! Your Sharingan Rank +1, enabling Mangekyo Sharingan."
"Ding! Congratulations, Master! Your Sharingan Rank +1 again, enabling Eternal Mangekyo Sharingan."
"Ding! Congratulations, Master! You have obtained the Sage Body."
Uchiha In, who was about to go to sleep, suddenly heard the System's doll-like voice.
Rumble!
In an instant, a tremendous life force and unparalleled spiritual energy surged out of his body, forming a powerful pressure, while an incomparable Chakra stood independently yet united, becoming incredibly terrifying.
Uchiha In closed his eyes at this moment, his expression one of pure enjoyment.
He could feel that every cell within his body seemed to be breathing in pleasure.
Suddenly, he opened his eyes, and the Sharingan with Three Tomoe in them spun rapidly, merging, and finally, forming a shape difficult to describe with words.
Those Eternal Mangekyo seemed to contain the entire starry sky—dark, profound, and mysterious.
The powerful spiritual energy and physical energy merged harmoniously, forming a massive Chakra that solidified like a tangible entity, creating a terrifying vortex of Qi.
The pressure was like a prison, the Qi vortex like blades, and Uchiha In's room was instantly destroyed.
"This feeling is simply too exhilarating."
After a while, Uchiha In retracted his Aura. If not for seeing his room in utter chaos and feeling his strength skyrocketing like a rocket, Uchiha In might have even thought he was dreaming.
It was too unreal; just moments ago, he had suddenly acquired the Eternal Mangekyo Sharingan and the Sage Body.
If Uchiha In had previously estimated that he could only defeat a Jonin, or even an Elite Jonin, now, Uchiha In could feel that even if he faced a Kage-level opponent, he might not lose!
He even felt that he could defeat Hiruzen Sarutobi now!
Of course, this was Uchiha In judging Hiruzen Sarutobi's current strength based on Hiruzen Sarutobi's power decades later in the original work; whether he could actually win was still unknown.
It was also possible that Uchiha In had overestimated his own strength due to suddenly acquiring such immense power.
However, regardless of whether he could defeat Hiruzen Sarutobi now, he would definitely stand at the pinnacle of the Ninja World in the future.
If Uchiha Madara could use the Eternal Mangekyo and Hashirama's cells, which retained Sage Body power, to cultivate the Rinnegan, he could certainly do the same.
Coupled with the various rewards the System would provide in the future, Uchiha In was confident he could stand at the pinnacle of the Ninja World, and even easily defeat Ōtsutsuki Kaguya.
Uchiha In had no idea that he would truly "easily defeat" Ōtsutsuki Kaguya in the "future."
"In, what happened? Why is your place such a mess?"
Just as Uchiha In was fantasizing, Uchiha Mikoto was disturbed by the commotion in Uchiha In's room and quickly closed the System interface, coming to Uchiha In's room.
She saw that Uchiha In's room looked as if it had been destroyed by a powerful Wind Release.
The quilt, mattress, clothes, and even the entire bed and table were scattered everywhere.
"Was your room destroyed by someone using Ninjutsu? Why is it like this?" Mikoto's face was filled with shock.
Uchiha In came back to his senses, looked at his messy room, and scratched his head.
He had just received the System's reward, and it had happened spontaneously; it was truly hard to explain.
Uchiha In was different from Tsunade and Mikoto. Tsunade and Mikoto each received the Eternal Mangekyo and the Sage Body separately, so they didn't cause much commotion. Uchiha In, however, received both abilities simultaneously, and their combined enhancement and coexistence led to such extensive destruction.
"Oh, that. My strength suddenly had a Breakthrough just now, which might have caused a rather large commotion," Uchiha In thought for a moment and explained.
"Who has a Breakthrough in strength that causes this kind of commotion?" Uchiha Mikoto smiled. In her mind, Uchiha In must have been experimenting with some Ninjutsu to cause this situation.
"You, ah. I wonder how you'll sleep tonight," Uchiha Mikoto said exasperatedly.
"Can't I just sleep with you tonight, Mikoto-nee?" Uchiha In said nonchalantly.
"How can that be, In? You're so big now, how can you still sleep with your older sister?" Hearing Uchiha In's words, Uchiha Mikoto said, her face flushed.
Uchiha Mikoto hadn't seen Uchiha In in half a year. Although they missed each other greatly, they had actually grown somewhat distant in certain aspects.
Previously, Uchiha Mikoto always slept with Uchiha In, but now seeing Uchiha In, who had grown much taller, with a more handsome face and masculine charm, Mikoto felt her heart pounding and was a little flustered.
"Mikoto nee-san, besides being my sister, you're also my girlfriend, you know. Isn't it only natural for me to sleep with my girlfriend?"
Uchiha In said with a mischievous smile.
A loose, hip-length nightgown was worn by Mikoto, but it couldn't conceal her already well-developed, beautiful figure.
Uchiha Mikoto's entire body was as fair and pristine as solidified cream; her chest was full, making the already loose nightgown appear even looser, and her straight, slender legs trembled slightly with unease.
Uchiha Mikoto, now slightly shy, had her eyes half-closed. Her black hair moved without wind, flowing over her pure white, smooth skin onto her fragrant shoulders.
Her naturally exquisite face was exceptionally beautiful, and her slightly upturned, pink lips seemed to be coated with honey, tempting and captivating, causing one to lose composure at first sight.
Mikoto-nee, you've truly become even more beautiful.
Uchiha In's heart stirred, and he picked up Uchiha Mikoto, running towards Uchiha Mikoto's room.
"In, what are you doing?" Uchiha Mikoto was startled when Uchiha In suddenly picked her up, a sense of panic washing over her, as if she sensitively anticipated something.
Chapter 80: Mikoto's 'Tolerance'
What to do? In this situation, is something going to happen?
But I haven't prepared anything yet!
Her hands tightened around Uchiha In's neck, and Mikoto grew even more nervous.
She had just seen the monthly mission and already felt very shy. Now, feeling that she might truly become a real woman, her cheeks flushed with even more shyness, her whole body went soft, and her eyes even welled up with a hazy mist.
Uchiha In actually just wanted to scare Mikoto, but when he looked down, he found that Mikoto's eyes were actually misty.
She's not crying from fright, is she?
Forgive Uchiha In, who was a male in both his past and present lives; he didn't know this was a sign of Mikoto's arousal. Instead, he thought Mikoto was resisting.
Gently placing Mikoto on the bed, Uchiha In also gently embraced Mikoto's waist.
Mikoto trembled all over, like a startled little bird.
"Alright, alright, Mikoto-nee, I don't want to do anything yet. I just want to hold you to sleep, like before."
