Minato Namikaze's composed face suddenly turned anxious, and he solemnly bowed to Shinsei.
Shinsei helped Minato to his feet.
"The future I'm about to reveal will have a huge impact on the world today. Can you guarantee you won't tell anyone else?"
Minato Namikaze gritted his teeth and said firmly, "Please, Shinsei- kun, tell me. I will absolutely not reveal any information to anyone else."
"Okay." Shinsei nodded. He trusted the character of the future Fourth Hokage, and besides, even if it were revealed, it wouldn't cause him much loss.
" Minato, before I tell you about Kushina's future, let me tell you a story."
"I have a good friend who lost his parents when he was born. The villagers don't like him, they call him a fox demon, and they don't allow other children to play with him."
But he never got discouraged or complained; he just attracted everyone's attention in a funny way.
Later, thanks to his optimistic personality, he made many friends and changed other people's opinions of him.
Do you think my friend is living a good life?
The exceptionally intelligent Minato picked up on the implied meaning in her words and immediately replied, "Oh no, why did your friend lose his parents?"
Shinsei grinned, looking at Minato Namikaze in front of him. "Because my friend's mother was ambushed while giving birth, releasing a giant monster, and my friend's father died trying to seal that monster."
By the way, would you like to know my friend's name?
Minato Namikaze had already guessed what was going on after hearing the story, but he still couldn't help asking, "What's his name?"
" Naruto Uzumaki."
His surname is Uzumaki! Minato Namikaze understood that Shinsei wouldn't tell this story for no reason, so the characters in it must be related to him and Kushina.
If he were to marry Kushina and have children, his surname would only be Uzumaki.
"Your friend's father and mother are..." Minato still held onto a sliver of hope, for the story Shinsei was about to tell did not have a happy ending.
"My friend's mother was none other than Kushina Uzumaki," Shinsei said, staring intently into Minato's eyes, "And his father was none other than you, the future Fourth Hokage, Minato Namikaze!"
Shinsei's words were brief, but contained a wealth of information, causing Minato to involuntarily take two steps back.
After a long while, he came to his senses, feeling a mixture of joy and sorrow. He was happy that he and his beloved Kushina Uzumaki had finally gotten together, but the ending of the story was not what he had hoped for.
"I can't accept this ending." Minato Namikaze gritted his teeth; he absolutely refused to accept Kushina dying like that.
Since Shinsei has said these things, there must be a solution.
Minato bowed again. "Please tell me, Shinsei- kun, how to rescue Kushina!"
He raised his head, his gaze solemn and resolute.
"If there is anything Shinsei needs my help, I will never refuse!"
"Haha, it's so different talking to smart people." Now that Minato knows there's no such thing as a free lunch, things are much easier to handle, and Shinsei doesn't need to rack his brains to persuade him anymore.
"I do need your help, but you're too weak right now. Don't rush things regarding Kushina; there's still plenty of time."
Shinsei took out a storage scroll, and then took out another scroll from it.
"Remember your promise." Shinsei handed the scroll to Minato.
Minato said solemnly, "I will never forget."
He unrolled the scroll, which contained information about a Ninjutsu — the Flying Thunder God Technique.
How could Minato Namikaze not know the Flying Thunder God Technique?
Now that Minato has mastered the Rasengan, if he also learns the Flying Thunder God Technique, he'll be a mini-version of the Fourth Hokage.
In this world, Minato and Shinsei are the same age, Chakra reserves are already quite considerable, much stronger than Sasuke's at the same age. If he learns the Flying Thunder God Technique, the only thing he lacks to become a strongman is experience.
On the battlefield of this Shinobi World War, as long as you don't die, your experience will naturally grow rapidly, and once you've mastered the Flying Thunder God, dying won't be so easy.
Shinsei refused to reveal any further details and saw Minato off with mixed feelings.
Having dealt with Minato Namikaze, Shinsei was overjoyed. When teaching Minato Flying Thunder God Technique, he had no reservations whatsoever. What did the rules of Konoha have to do with Konoha in the other world?
Thinking back to when Naruto will bring Minato Namikaze and Kushina Uzumaki into his own world, will he call them "Mom" and "Dad" when they're the same age as him?
Just thinking about it makes me happy.
Then, bring over the younger version of Tsunade. Whoever obeys will be called "teacher," and whoever disobeys will be called "Tsunade."
By the way, if two Tsunade were to bet against each other, who would win?
Over the next few days, whenever Minato had free time, he would come over to ask Ninjutsu about the Flying Thunder God Technique, which made Jiraiya a little jealous, but he could only pretend to be magnanimous.
The Flying Thunder God technique drawn by Shinsei is not the same version as the one given to Minato Namikaze.
Little did he know how Flying Thunder God Minato Namikaze learned the original Thunder God Technique. In order to learn it, he had completely altered the Ninjutsu.
Fortunately, Minato only asked about the most basic Sealing Jutsu, so he didn't give himself away.
A dense array of black and white Sealing Jutsu appeared on Shinsei's body. Constructing such Sealing Jutsu patterns required precise manipulation. Although Shinsei's Chakra control was strong enough, he was still exhausted and covered in sweat.
We're already halfway through the project, and I believe that in a few more days, we'll be able to complete all the Yin-Yang Seal. At that time, I'll be able to instantly activate Sage Mode, just like Hashirama Senju.
Knock, knock, knock. There was a knock on the door.
"Wait a moment." Shinsei finished inscribing the Sealing Jutsu runes, got up from the wooden bed, put on his clothes, and opened the door.
Upon seeing the person who arrived, Shinsei was about to call him "Grandpa," but quickly changed his address to " Kenta- senpai."
He gestured for the visitor to sit down; this was his grandfather in this timeline.
Kenta looked around the room. "Such amazing Chakra manipulation!"
As a member of the Senju clan, Kenta naturally knew Earth Release. He understood that Shinsei's Earth Release was powerful, but the required Chakra control was terrifyingly high.
" Kenta -senpai." Shinsei poured a glass of water and placed it on the table he had created using Earth Release.
Kenta pulled out two letters. "This one is from the Lord Hokage, and this one is from Lady Mito."
Shinsei opened the first letter, which read that the Third Hokage had promoted Shinsei to the rank of Jonin Konoha. Inside was Shinsei's ninja identification document.
One of the cards also reads that Hiruzen Sarutobi, in the name of the Hokage, invited Shinsei to Konoha.
This is equivalent to the Third Hokage giving Shinsei an identity in this world.
Opening another letter, one finds Mito Uzumaki inviting Shinsei to the Senju Clan's territory in Konoha, and offering Shinsei a house.
The letter also stated that she had given thought to the sealing of the Dragon Vein's energy, but she would only be certain of the specifics after witnessing the true Dragon Vein energy.
Mito was much more generous, giving him a house as a gift, while Hiruzen Sarutobi only gave him a Jonin and nothing else.
However, in his own world, he wasn't Jonin yet; he was still Genin.
Even Shikamaru, who was promoted to Chunin in the original work, remained Genin because he didn't get enough opportunities to demonstrate his abilities.
I hope the teacher will recognize this document when I take it back.
Knock, knock, knock, the door was knocked on again.
"Please come in."
Orochimaru Earth Flow a smile on his face.
"Ah, Shinsei has a guest. I just came to ask how many more days your Yin-Yang Seal will take to work?"
"Seven or eight days, I guess," Shinsei replied casually. As soon as the words left his mouth, his eyes sharpened as he stared at Orochimaru, who was grinning.
"Who are you?"
