Chapter 160: Tsunade Becomes a Ninjutsu Test Subject
"Tsunade-sama~"
As a medical ninja, Rin hurried forward to check Tsunade's condition. Only after confirming that nothing was wrong did she finally let out a sigh of relief.
After that, Rin looked at Uchiha Hikari, this clanmate of Obito's, with eyes full of awe.
Tsunade, an idol to female ninja across all the villages of the shinobi world, had been so easily defeated by Uchiha Hikari.
If this weren't a time of peace, Uchiha Hikari would have replaced Tsunade as the figure admired by female ninja in no time at all.
"Relax, she's fine. I'm treating her hemophobia."
"By the way, if you're worried about her, why don't you go in and check on her yourselves?"
Uchiha Hikari made a suggestion.
"Huh? When you used the genjutsu, weren't you conscious inside it? And shouldn't this kind of thing be cured instantly?"
Kushina noticed something odd.
"Oh, this is an improved version of Tsukuyomi. I modified the rate of time flow inside it. I don't need to stay inside to control it the whole time."
What Hikari referred to as "improved" was, in essence, pushing ordinary Tsukuyomi closer toward Sealed Tsukuyomi, Limited Tsukuyomi, and Infinite Tsukuyomi.
Aside from normal Tsukuyomi, the other three could all operate autonomously.
So why did Hikari do this?
The root reason was that during the previous Tsukuyomi experiment, Kakashi's behavior had been far too eye-searing, leaving a psychological shadow on the pure-hearted Hikari.
If Kakashi was already like that, then Tsunade, someone who was naturally part of the Senju clan, and even Senju Hashirama's granddaughter, would be extremely dangerous.
To avoid once again feeling the urge to gouge out her own eyes, Hikari chose to let Tsunade heal herself in a fully automated manner.
"It's probably better not to go in and disturb Tsunade-sama's treatment…"
Just as Rin finished speaking, Tsunade suddenly opened her eyes and sat straight up.
She didn't say a word.
Her gaze swept over everyone present, lingering on Shiromo for a moment, before her entire body relaxed and she collapsed back onto the sofa.
"You're so young. Where did you even learn all these tricks?"
Tsunade said weakly to Hikari.
"So what did you experience in there?"
Hikari asked with curiosity.
She didn't dare look.
She was afraid of seeing something too stimulating.
But listening should be fine, right?
Just hearing a description couldn't possibly be so perverse that it would make her want to stab her own ears deaf.
"Hm? You don't know?"
Tsunade immediately became alert. The words she was about to say were swallowed back down.
Hikari was a senior in generations, but in terms of actual lived experience, she only had the amount of time of an ordinary girl. Even coming from the Warring States era couldn't compare to a true old fox like Tsunade.
"Tch. It's probably something indecent anyway. If you don't want to say it, forget it. I don't want to hear it either."
Seeing Tsunade's guarded expression, Hikari immediately curled her lips.
Hikari's Tsukuyomi truly lived up to its reputation in the original story as something that could turn into a VR game.
Leaving aside Infinite Tsukuyomi's outcomes, absorbing chakra and reviving Kaguya, its core effect was simply "fulfilling the desires of those caught in the genjutsu."
Hikari's Tsukuyomi, however, could modify this setting.
For example, earlier, it had guided Kakashi into reliving two of his past scripts.
And just now, it had been set with the basic premise of "curing Tsunade's hemophobia," then allowed to develop on its own.
Originally, there shouldn't have been any problem.
But this was Hikari's first attempt at modifying Tsukuyomi's parameters. She hadn't conducted any prior tests and had directly used it on Tsunade.
Naturally, some errors were inevitable.
For instance…
Compared to Infinite Tsukuyomi's completely neutral dream worlds tailored to each individual, Hikari had unconsciously mixed some of her own emotions into this Tsukuyomi dream.
Her bias toward the Senju clan (which might not even have been biased).
Her dissatisfaction with Tsunade's lack of trust in Shiromo, which had led to disagreements and conflict, and her desire for Tsunade to sincerely apologize for it.
And so…
Tsunade experienced an extremely bizarre Tsukuyomi dream.
Infinite Tsukuyomi had one advantage over ordinary Tsukuyomi: immersion.
Infinite Tsukuyomi was like the Omnipotence that swapped the identities of Ōtsutsuki Boruto and Uzumaki Kawaki, it constantly corrected a person's thinking.
It made them believe that this was reality, not a genjutsu.
Only Tenten, who possessed the Sage of Six Paths' ninja tools, managed to resist for a while.
When Tsunade first entered Hikari's Tsukuyomi dream, she was clearly aware that she had been caught in a genjutsu.
But knowing it was fake didn't mean she could control her emotions.
As for the exact content, since Hikari didn't know, Tsunade decided to let it rot in the depths of her heart and never tell anyone.
In truth, nothing perverted actually happened. But in terms of the outcome…
Tsunade was extremely glad that she had restrained her hemophobia in time and triggered the mechanism to exit the genjutsu, waking up.
Otherwise, if she had been even a little later, it might have already been too late.
Why did Tsunade scan everyone as soon as she woke up, and even stare at Shiromo for a moment?
Because there were some elements involving Shiromo in that Tsukuyomi dream.
If she hadn't managed to get out in time, then there was a song called 'Mang Zhong'(Eng Title: Grain In Ear) that could perfectly describe what might have happened when Tsunade woke up again.... "Whenever I think of you, I just Wu Oh Oh Oh."
This absolutely could not be known by anyone else. It was far too embarrassing.
Likewise, Tsunade was very thankful that genjutsu wasn't the same as dreaming.
If she had dreamed something like that, then when she woke up, this Hokage might temporarily turn into the Mizukage.
Fortunately, it was genjutsu. When she woke up, her clothes were still dry.
"Using Tsunade as a test subject for improving Tsukuyomi? Speaking of which, I have an idea too."
Shiromo looked at the slightly absent-minded Tsunade: "Hokage-sama, if you've recovered well, help me with something."
"Help? No problem. What do you need me to do?"
Tsunade snapped back to her senses. Faced with Shiromo's "request" she hesitated for barely a second before immediately agreeing.
Wasn't this the perfect opportunity to repair her favorability with him?
"You're agreeing that decisively? This could be life-threatening. I only thought of using you because I know you have Creation Rebirth. You can still refuse."
Shiromo reminded her.
While being cut in half at the waist, Tsunade in the original story not only survived, but also used up her remaining chakra to heal the other five Kage.
Meanwhile, Asuma, who was cut in half by Momoshiki, didn't even last until reinforcements arrived and died on the spot.
That was the difference.
Even without activating Creation Rebirth, Tsunade still had Senju and Uzumaki blood.
"Since you know about Creation Rebirth, then you don't need to worry about my life."
Tsunade's expression also became serious: "Go on. What do you want me to do? Do we need to change locations?"
"Let's find an empty backyard."
"Alright."
Shiromo and the group arrived at the backyard of the luxury room at the hot spring inn.
There was also a small, separate pool in the backyard.
But they weren't here to soak in the hot spring.
