When Kushina became the Jinchuriki of the Nine - Tailed Fox, she was not allowed to leave the village to prevent those with ulterior motives from obtaining the power of the Nine - Tailed Fox and using it against Konoha.
The Nine - Tailed Fox, being the most powerful among the Tailed Beasts, is definitely not easy to control. Kushina now has Adamantine Sealing Chains, which can absolutely restrain the Tailed Beasts, and the sealing ninjutsu passed down through generations in the Uzumaki Clan. Otherwise, the Nine - Tailed Fox would have escaped long ago.
However, even now, Kushina has to bear the negative emotions contained in the chakra of the Nine - Tailed Fox every day. If one day Kushina can't bear it anymore, she will go berserk.
As for why Mito Uzumaki, the previous Jinchuriki of the Nine - Tailed Fox, didn't have such a problem, it's because she was born in the Warring States period and was extremely powerful. It was a piece of cake for her to suppress the Nine - Tailed Fox.
Not to mention that her husband was Hashirama. Even if the Nine - Tailed Fox had the audacity of a lion, it wouldn't dare to affect Mito.
But I digress. Anyway, since the war started, Kushina, without Minato Namikaze by her side, has been really bored. However, Tsunade and others who are familiar with her are not in the village. So she can only talk to her good friend Mikoto Uchiha. But because of the Uchiha Clan's identity, she can't stay with her for too long without Minato Namikaze's company.
Finally seeing Yue Yan, an acquaintance, Kushina won't let him leave easily.
After that, Yue Yan became the go - to guy who accompanied Kushina to have fun. Whether it was eating delicious food or going shopping, Yue Yan paid for everything.
In Kushina's words, "As a good younger brother, what's wrong with spending some money for your elder sister?"
Although she said so, Kushina didn't go too far and didn't let Yue Yan spend too much money. What Kushina mainly enjoyed was the feeling of getting along with her family.
On the snack street, seeing Kushina buy a portion at every stall and then eat only one bite before throwing the rest to him, Yue Yan sighed helplessly. If he wasn't a big eater himself, these foods would probably go to waste.
Kushina was munching on a bunch of Three Colouring Pills. After giving the rest to Yue Yan, she couldn't help but sigh with emotion.
"Luckily it's little Yue Yan accompanying me. If it were Minato Namikaze, he would be full after just a little, and I wouldn't have tasted so many snacks."
In response, Yue Yan could only give an awkward but polite smile.
Just like this, they walked and ate all the way. Even though Kushina only took one bite of each thing, she was full now.
Kushina bounced along on the way home. She turned her head and smiled at Yue Yan, thanking him.
"Thanks, little Yue Yan, for accompanying me shopping today."
"Where is that. I'm also very happy to accompany Sister Kushina shopping."
Hearing this, Kushina showed a smile. What she wanted was this feeling of being accompanied by family.
At this time, Kushina noticed Mikoto Uchiha who was on her way home after buying groceries. She greeted her with a smile.
Seeing Kushina, Mikoto Uchiha was also very happy. Then they chatted without caring about anyone else around.
Suddenly recalling something, Kushina sidled up to Mikoto Uchiha with a playful look on her face.
"Hey, you've been trying with Fugaku for ages. Got any results yet?"
Upon hearing this, Mikoto Uchiha's face instantly flushed. She stammered shyly, "Well... there's news. When I went to Konoha Hospital for a check - up before, they said I'm two months along."
"Hey, I'm your BFF! How could you keep such big news from me? I'm sulking!"
As she spoke, Kushina slung her arm around Mikoto Uchiha's shoulder, wearing a lewd smile on her face.
Yes, in Yue Yan's eyes, that smile was lewd. Seeing Kushina with her arm around Mikoto Uchiha, it felt like she was molesting an innocent woman.
Although Yue Yan was complaining in his heart, he also paid attention to their conversation. At this time, it meant that Itachi Uchiha, whom many netizens in his past life revered as the God of Itachi, was about to be born.
Regarding Itachi Uchiha, some people said he was a brute who killed his own Mother and Father and massacred the entire Uchiha Clan, while others said he had no choice and tried to excuse him.
But Yue Yan remained neutral. After all, Itachi Uchiha was still young then, and the ninja world itself was messed up. His act of going to extremes and shouldering everything alone was understandable.
Even so, it's also true that few normal people could understand him.
Itachi Uchiha's deep love for his younger brother and his achievements in dealing with the Living Corpse Reincarnation army during the Fourth Great Ninja War were undeniable.
In short, Yue Yan thought that with proper guidance and filling his mind with some normal thoughts, combined with his natural talent, Itachi Uchiha could still be set on the right path.
However, that was all in the future. Anyway, Yue Yan wasn't well - acquainted with the Uchiha Clan, and he couldn't guarantee what would happen later.
Just as Yue Yan was thinking about these things, Kushina suddenly pulled him over and introduced, "Mikoto Uchiha, this is my younger brother, Yue Yan. Yue Yan, this is my bestie, Mikoto Uchiha."
Hearing this, out of courtesy, Yue Yan responded.
"Hello, Sister Mikoto Uchiha."
"Hello, Yue Yan."
Mikoto Uchiha reached out her hand with a gentle smile and shook hands with Yue Yan.
"Since you're Kushina's younger brother, you're also my younger brother. You're welcome to visit the Uchiha Clan anytime."
"Sure, I will."
After chatting for a few more minutes, Yue Yan and Kushina said goodbye to Mikoto Uchiha.
In the following days, Yue Yan got back to his normal routine. He had been cultivating immortality in the Bone Forest. To avoid affecting his cultivation of immortality, Yue Yan didn't even send a kage clone to Konoha Hospital to lend a hand.
Aunt Natsuki didn't mind. It'd be great if Yue Yan could come to help, but it didn't matter if he didn't. After all, this was the job of those doctors.
After about half a month of recuperation in Konoha, Hizashi Hyuga's Squad headed to the battlefield again. This time, they were bound for the battlefield in the Land of Wind.
As the front - line commander of the Land of Wind, Jiraiya was also very excited upon learning that the village had sent a ninja with extremely powerful Mystical Palm Technique. After the support troops arrived, without any airs, he directly greeted them at the camp entrance.
When Jiraiya received Yue Yan's mission letter, he couldn't help raising his eyebrows and burst into laughter, patting Yue Yan on the shoulder.
"Hahaha, as expected of my disciple, the disciple of Gama Sage Jiraiya! You really have the ability!"
It wasn't appropriate to just stand there talking. After saying that, Jiraiya led the way towards the camp.
Then he asked Yue Yan to come to the meeting tent together with the capable Jonin.
As soon as they sat down, Jiraiya looked at Yue Yan and got straight to the point. "The most pressing issue at the front - line right now is how to handle the constant poison attacks from the Sand Ninjas. Now that you're here, Yue Yan, the situation should improve. As your teacher, I have great confidence in your Mystical Palm Technique. Later, you go to the medical department, get familiar with the situation, figure out the composition of the Antidote as soon as possible, and finally make the Antidote."
Knowing that it wasn't the time to joke around, Yue Yan nodded and took on this task.
Earlier, everyone had heard the conversation between Jiraiya and Yue Yan, and they felt really relieved about Jiraiya's disciple.
