Naruto : Minato back to the past

"Roar!"

 The moment the black seal appeared, a sharp roar rang in Minato's ears.

 The roar was so shocking that at this moment, Kushina couldn't help but tremble.

 Her bright eyes turned into scarlet vertical pupils in an instant.

 "snort!"

 Seeing this, Minato snorted coldly, and then the five fingers of the hand pressing on Kushina's abdomen flashed with chakra, and pressed directly on the Four Symbols Seal.

 "Crack!"

 He turned the seal slightly, and the abnormality in Kushina's eyes disappeared instantly.

 "It's the Kyuubi!"

 After regaining her composure, Kushina frowned and said that she was of course aware of her situation, and now she had made some progress in the practice of sealing techniques.

 Minato nodded. The Nine-Tails in her body should have been drawn out by her chakra and sensed something.

 "Buzz."

 Just as the two were hesitating, the Four Symbols Seal on Kushina's abdomen suddenly lit up, and the intricate patterns that made up the seal began to slowly operate at this moment.

 "It's struggling!"

 Kushina's face gradually darkened. She learned from Mito how terrifying the power of the Nine-Tails in her body was. At the same time, as a Jinchūriki over the years, she also had her own experience.

 Mito had sealed the Nine-Tails in her body for several years, and when she did the sealing, she was already at the end of her strength.

 Although this Four Symbols Sealing Style is still powerful, the power of the Nine-Tailed Fox is too strong, and the power of the sealing style is gradually weakened over time.

 However, the current strength of the seal is still able to imprison the Nine-Tailed Fox tightly.

 Now the Nine-Tailed Fox was struggling violently. Kushina didn't understand why its emotions suddenly became so excited.

 "Damn you, Fourth Hokage!"

 The angry voice of the Nine-Tailed Fox was heard from deep within Minato's soul. The Nine-Tailed Fox in Kushina's body was being attracted, so naturally the creature inside Minato's body would not be without reaction.

 "Damn Fourth Hokage, Hokage!?"

 At this moment, Kushina beside Minato suddenly exclaimed in surprise, and when Minato heard that, his pupils suddenly shrank, and then he looked at her.

 "Kushina can you actually hear the voice coming from deep inside my soul!?"

 He was shocked; the current situation was beyond his control.

 "Kushina, what are you talking about?" However, Minato would certainly not reveal this secret easily, and immediately pretended to be stunned.

 Kushina shook her head and said, "It seems that the Nine-Tailed Fox in my body said something strange just now."

 "So far, our Konoha Ninja Village has only had three generations of Hokage, so how can there be a fourth generation?"

 Minato nodded with a fake smile, but in reality he was extremely shaken.

 "It seems that there may be a special connection between the Nine-Tailed Fox." The voice of Adult Minato was also heard.

 "Yeah," Minato responded, then his eyes darkened.

 "I'm going to strengthen your seal a little bit more," he said, looking at Kushina.

 Kushina didn't have any objections, but she said in surprise: "You can do this now?"

 "It was me who taught you Fuinjutsu." She curled her lips because strengthened Fuinjutsu left by Lady Mito, which was something she couldn't do even now.

 Minato chuckled. Kushina was starting from scratch, while he was just picking up some techniques that he had already mastered.

 Naturally, there is a huge gap in the growth rates between the two.

 He formed seals with his hands, while Kushina looked extremely calm.

 When Minato said he wanted to strengthen the sealing, she knew which seal he should use.

 "Twin fortification seal!"

 Minato shouted, and after forming a hand seal, he pointed his right index finger at the center of the Four Symbols Seal on Kushina's abdomen.

 The center of the seal was a blank space surrounded by a vortex. As Minato pointed, black lines began to rotate from the center of the vortex.

 A few seconds later, another vortex formed in the blank space of the sealed vortex.

 After completing the seal reinforcement, Minato formed a sub-seal. The flying thunder god seal he had left on Kushina's abdomen were gradually integrated into the seal, and finally faded and disappeared.

 "Phew! Done."

 After completing the Fuinjutsu , Minato exhaled a breath of foul air. Although the strengthening and combination Fuinjutsu s did not consume much chakra, they were extremely energy-consuming.

 As she perceived, Kushina's slightly chaotic chakra fluctuations began to calm down again.

 "The Twin Fortification seal with the Four Symbols Seal, so this is what it looks like?" Kushina herself was immersed in Minato's Fuinjutsu just now

"In this way, the seal will not loose for several years." Minato said that Kushina was able to completely suppress the Nine-Tails in the past because she awakened her special ability as a descendant of the Uzumaki clan.

 At that time, Kushina herself re-set the seal that Mito left for her, and combined with her own abilities, the strength of the seal was even stronger than the Eight Trigrams Seal that Minato set for Naruto.

 If it weren't for the fact that the strength of the seal was greatly weakened during childbirth, no one except Kushina herself, not even Minato, would be able to remove the seal on her.

 Kushina finally came to her senses and nodded.

 But from her eyes, Minato already saw some passion.

 It was obvious that she was not convinced that she had lost to him.

 After re-strengthening the seal, Minato frowned, pondered for a moment, and said, "It seems that today's matter must be dealt with..."

 However, before he could finish his words, Kushina grabbed his arm and said, "Don't tell the hokage about this, otherwise he will have a group of people to follow me all day, which is really annoying."

 She obviously knew the consequences of her seal being loosened if the Hokage knew about it.

 Minato explained: "I know, but this is also for your safety."

 "Haven't you already strengthened the seal? Besides, when you go out on a mission, they will definitely not let me leave the village. In this case, what kind of danger could I encounter?" Kushina said with a pout.

 There was nothing wrong with what she said.

 He was the one who reinforced the seal of the Nine-Tails with his own hands, so Minato was not worried. Kushina had been kidnapped by the ninjas of the Cloud Village in the past, but that was history.

 The Second Ninja World War in his previous live lasted for nearly two or three years. At that time, the Kumo took advantage of the weakness of Konoha's defenses to capture Kushina.

 However, due to the appearance of Minato, the duration of the war in both the Land of Rain and the Land of Wind was greatly shortened, and the Second Ninja World War lasted only about a year.

 Today's Konoha is the most formidable of the five major ninja nations. Even the Kage from other nations do not have the ability to sneak into the village and abduct Kushina.

 So, Minato formed seals with his hands and removed the barrier covering the room, then looked at Kushina and shrugged helplessly.

 "All right."

 "When you do your mission promise me that you must be careful and don't push yourself." She reminded him again when they said goodbye in front of Minato house.
