The first time she fused with Sage Art Chakra, it completely drained Nohara Rin's energy.
She slumped directly to the ground, panting heavily to the point she didn't even have the strength to move, and her clothes were soaked with sweat, stained with a lot of dust.
'So this is what real exhaustion feels like; I just want to fall asleep like this...'
Such a thought flashed in Nohara Rin's mind, and soon the fatigue overtook her, making her fall asleep.
"Asleep?"
Uchiha Yoichi noticed Nohara Rin's breathing gradually stabilize, then approached her slightly to take a closer look.
One of the roots of the Fourth Great Ninja War, who would have thought it could be a normal girl; and aside from her delicate appearance, she was just lively and youthful.
Uchiha Yoichi extended his hand, adding a Flying Thunder God Mark to the Sage Curse Seal on the back of Nohara Rin's neck, perfectly aligning with it.
"Three-Phase Seal!"
After applying the Flying Thunder God Mark, Uchiha Yoichi added a seal for a delayed activation of Reverse Flying Thunder God Jutsu, a technique researched by Uzumaki Minami, named Three-Phase Seal, corresponding to the three Tamoe of the Flying Thunder God Jutsu.
After completing this, Uchiha Yoichi's eyes transformed into Mangekyo Sharingan, leaving a Transcription Seal on Nohara Rin's heart.
The pupil power of Ōmononushi no kami, this power could temporarily ensure Nohara Rin wouldn't die even if her heart was shattered, and then trigger the Reverse Flying Thunder God Jutsu to bring her before Uchiha Yoichi.
Doing so much preparation for a young girl, Uchiha Yoichi hoped Uchiha Obito would seize the opportunity, living up to his efforts.
After a while, Nohara Rin slowly woke up, discovering she had a blanket over her, while Uchiha Yoichi leaned against a tree nearby.
Nohara Rin quickly got up, embarrassed, and apologized, "Sorry, Lord Yoichi, I actually fell asleep just now..."
"No worries, that was my Shadow Clone. Now that you're awake, you should go back and rest well. Come back for the second session in three days."
With that, Uchiha Yoichi's Shadow Clone dissipated into smoke.
Seeing this, Nohara Rin couldn't help but think to herself how considerate Lord Yoichi was, not only covering her with a blanket but also keeping watch with a shadow clone... if only Kakashi could be like that~
Unfortunately, during the time she was surrounded by Hidden Rock Ninja, Nohara Rin already realized Kakashi didn't have those feelings for her, and when they both faced danger, he even passed on Obito's feelings...
Thinking of this, Nohara Rin sighed inwardly, then she got up, picked up the blanket, planning to wash it clean and return it to Lord Yoichi the next time.
The Sage Art Chakra contained Uchiha Yoichi's will, gradually influencing Nohara Rin; though it couldn't erase her personality, it would make her deeply acknowledge Uchiha Yoichi and everything about him.
After leaving Uchiha Clan Land, Nohara Rin was still drained of energy, slowly making her way home; however, on her way, she suddenly heard someone call her from behind.
Turning back, Nohara Rin saw Kushina and greeted, "Sister Kushina, are you out shopping?"
"Yes, today Minato plans to entertain his teacher, so I'm making something good for them; too bad I couldn't get any Magic Mountain Lamb, even though they were supposed to sell two hundred pounds this afternoon, by the time I got there, not even half a pound was left..."
Seeing Nohara Rin, Kushina immediately vented the frustration of queueing earlier.
Then noticing Nohara Rin covered in dust and looking quite fatigued, she couldn't help but ask, "Rin, did you just go train?"
"Sort of, I've been learning Medical Ninjutsu from Teacher Minami lately..."
Nohara Rin explained the situation to Kushina, then clenched her small white fists slightly, saying, "Sister Kushina, I don't want to be a burden to my teammates anymore..."
"Minami even voluntarily teaches students now? That's a bit unbelievable..." Kushina frowned slightly upon hearing this, then continued, "But what's this Sage Curse Seal? I think I've heard Minato mention it..."
"It's the kind of Juinjutsu that Yuhi Kurenai and Hyuga Satomi used in the Chunin Exam, something that absorbs natural energy, turning Chakra into Sage Art Chakra, enhancing the power of Ninjutsu, Taijutsu, and Illusion Techniques..."
"Could that guy even develop Juinjutsu like that? It must have been Minami's doing..."
Kushina asked curiously but sensed Nohara Rin's exhaustion, knowing what she needed most now was rest, so she said, "Rin, go back and rest quickly; you look very tired."
"Then I'll head back first, Sister Kushina."
Nohara Rin also felt extremely tired; the recent fusion with Sage Art Chakra had completely drained her energy, and she could walk now because she had rested for a while.
After bidding Nohara Rin farewell, Kushina also returned home, finding Jiraiya already there, sitting at the table talking with Minato.
"Jiraiya-sensei, you're already here, huh? Wait a moment, I'll go make dinner now."
Jiraiya greeted her with a smile upon hearing this, "Yo, Kushina, Minato is indeed lucky to have you!"
"Hehehe, too kind!"
Kushina waved her hand, but a proud smile appeared on her face, making Jiraiya and Namikaze Minato chuckle; it was too obvious.
"By the way, Minato, have you heard of the Sage Curse Seal?"
Namikaze Minato pondered upon hearing this, then shook his head, saying, "Sage Curse Seal? Not something I'm familiar with. Is it related to Sage Mode? Kushina, why do you ask?"
