Watching the manga didn't give a deep impression, and the family's historical records were also vague, but if you combine the two, you'll find that Ōtsutsuki Kaguya was incredibly strong, a power level completely different from that of a Ninja.
Ōtsutsuki Kaguya gave birth to Otsutsuki Hagoromo, later known as the Six Paths Sage, and Hamura Otsutsuki.
One theory is that she fell in love with a mortal, married, and had children; another theory is that she "received the blessings of the crowd," self-conceived, and directly gave birth to two sons.
The mainstream view leans towards the latter, that is, she self-conceived and then gave birth.
This is terrifying. Ino, limited by her perspective, doesn't know why Ōtsutsuki Kaguya wanted to have these two sons. Someone who has lived for thousands of years shouldn't have thoughts of loneliness, emptiness, or needing companionship.
According to her understanding, Ōtsutsuki Kaguya simply had too much energy within her, some beneficial, some harmful. To achieve a higher level of self-improvement, she forcibly separated some of her authority and extraordinary characteristics, which resulted in her two sons.
To Ōtsutsuki Kaguya, these two sons were irredeemable harmful waste, and mother and son were naturally antagonistic on a causal level.
The Six Paths Sage and his brother jointly sealed their mother. Afterwards, Hamura went to the moon, and when the Six Paths Sage grew old, he separated the Ten-Tails to create the Tailed Beasts. He then further divided some of his authority and extraordinary characteristics, which led to Indra and Ashura. These two brothers already had a bit of the Adam and Amon vibe.
Working backward, you'll find that Ōtsutsuki Kaguya was simply ridiculously strong.
Ino's previous plan was to lie down during the Infinite Tsukuyomi, but the Yamanaka Clan's Mind Body Switch Technique showed her a possibility. If it were like Captain Ginyu, swapping into a powerful body, she wouldn't refuse.
Ino casually brushed him off, taking the opportunity to observe Sasuke's physical and spiritual energy.
The Uchiha Clan's bloodline, inherited from Indra, is indeed very strong.
Even with Ino isolating Sasuke's consciousness and spiritual energy, currently only able to mobilize physical energy, there's still a significant amount of Yin Release-leaning energy within Sasuke's body. For the Uchiha Clan, spiritual energy is already deeply ingrained.
Ino, having usurped his body, had no intention of helping Sasuke activate his Sharingan, nor did she know how to.
If the spiritual and physical energies don't match, even if the Sharingan is a plug-and-play cheat, an incompatible core means it cannot manifest.
Sasuke kept roaring. Ino searched for a long time but couldn't find Indra Chakra. She waved her hand somewhat disappointedly: "Stop shouting. I'll return your body to you soon. Your spiritual energy has great potential, but you don't know how to use it yet. Next time, when you're stronger, I'll come back to see."
She controlled the body to take two steps in place, estimating that the level of the Mind Body Switch was still too low, as the body's sluggishness was very noticeable.
"Sasuke" raised his right hand and looked in Iruka's direction. According to her estimation, shouting "I surrender" at this moment would end this 'selecting capable people from acquaintances' duel. But she didn't expect that just as her right hand was raised and the Hidden Mist Technique completely dissipated, seven or eight girls suddenly ran over, with Sakura leading the charge.
"Wow! Sasuke, you're amazing! Ino was beaten so badly by you! You're so great!"
"Sasuke, your moves are truly handsome!"
"Sasuke, I like you so much!"
Several girls squeezed "Sasuke" in the middle. One seemingly inadvertently hugged her arm, another grabbed her hand. "Sasuke's" five fingers on one hand were sometimes pulled by three people simultaneously.
Ino felt her scalp tingle. What was wrong with these girls?
Sakura was the fiercest, like an old hen protecting her chick, ferociously trying to push away the 'seductive vixen' beside her. Iruka saw the situation becoming chaotic and walked over, intending to end the duel. He didn't understand the Yamanaka Clan's Secret Technique, but as a Chunin who had been on the battlefield, he intuitively sensed something was wrong. However, as soon as he reached out, he was kicked away by Sakura, who had entered berserk mode.
Naruto held his head with both hands, his eyes wide open, looking at Iruka-sensei who had been kicked away, and then at "Sasuke" surrounded by many girls. His heart was incredibly complex. Shikamaru knew about the Yamanaka Clan's Secret Technique and was now covering his face with his hand, an expression of 'I don't know her'.
Ino, squeezed amidst the many girls, calmed down after her initial panic. What was she afraid of? What was there to be afraid of?
Even if she did something that angered both gods and men, Sasuke would take the blame, right?
As soon as she thought about taking the blame, her spirits immediately lifted.
The ubiquitous Yin Style Chakra within this body made her somewhat excited.
Sasuke sensed a hint of eagerness in her consciousness and quickly spoke to dissuade her: "What are you going to do? Weren't you going to return my body to me? Consider this round your win. I'll definitely win it back next time. Quickly release this technique."
Ino glanced at him: "Don't rush. You also find these girls annoying, don't you? I'll help you get rid of them once and for all. No need to thank me."
"Ah? ...This..."
Sasuke and Naruto are both straight men of steel. The difference is that Naruto is dense. Although he often peeks into the women's bathhouse and knows the importance of curves, and is very alluring when he transforms into a woman, Naruto doesn't understand why men like these things.
Sasuke is in a different state; he's generally at the level of "women only affect my sword-drawing speed." It's not that he dislikes them, but he feels he doesn't need them.
Ino guessed he was also very annoyed by these women. She thought she'd do a good deed today and solve it all for him!
Without another word, she pulled Sakura in front of her.
Sakura, who was holding her arm, was stunned, not knowing why "Sasuke" suddenly became so proactive.
Ino's eyes sparkled with electricity, and she said in a domineering CEO's tone: "Woman, you have successfully caught my attention. Lift your head and look at me."
"Ah? Ah! Ah, this... that I, I just... just..." Sakura's gaze drifted, her hands and feet were flustered, and her face was flushed.
Sasuke in the mental world was going crazy. What was this damned woman doing?!
"What exactly are you trying to do?! Is this helping me?!"
"Ah! You're going to kill me with anger!"
"Don't rush, don't rush. Didn't you hear those idiots just now cursing me? This is me helping you."
Relying on a sufficiently high level of Yin Release, Ino suppressed Sasuke's resistance in the mental world.
Outside, "Sasuke's" voice was extremely charming, and with sparkling eyes, she said to Sakura: "The Uchiha Clan only marries the smartest girls. Let's play a riddle, shall we? If you guess correctly, I'll allow you to take the Uchiha surname."
"Ah?!" Steam billowed from Sakura's head. Her usually clever brain was now mush. Was she really going to change her surname now? Her parents wouldn't object, would they? And wasn't this a bit too fast?
Thinking of herself becoming Uchiha Sakura, her heart almost leaped out of her chest.
