Since he recovered his memory, Minato has been systematically organizing the existing information and his own situation. He did not tell Sandaime and Jiraiya about his rebirth because he was afraid of affecting the course of history. After all, before he recovered his memory, he had changed the fate of many people just because of Kushina. This included his meeting with Kushina, which happened several years earlier than before. Kushina was also much stronger than before. He not only taught her the Shadow Clone Jutsu but also taught her some corresponding techniques.
The matter of training was also a decision he made after careful consideration. He naturally wanted to practice the Flying Thunder God Jutsu, but not now, because with Minato's current basic speed and physical skill, he could not exert its power at all. The Rasengan is just a jutsu that has not yet been fully developed. Although it was already quite powerful, he was not so lacking in attack power and explosive power now. With only a kunai in his hand, various ninjutsu, and speed, he had the confidence to defeat any enemy below the level of a jonin. The strength of a ninja is not only determined by the number and power of ninjutsu mastered. If there is no basic quality to match it, it is just strong on the outside but weak on the inside.
Minato knows this very well, and now his speed and overall quality have also reached a bottleneck, and it takes a certain amount of time to hone it before it can naturally improve. He doesn't want to do anything that will force the issue. The most important thing at the moment is to confirm everything he has found in himself. For this reason, he must enter the deep spiritual space again and meet the Nine-Tails. There are two ways. One is to use the Nine-Tails in Kushina's body, using the chakra resonance method like last time. However, according to the current situation, it is not advisable. So there is only the second way, which is to intensify the practice of the Uzumaki clan's fuinjutsu.
Although he now has all his memories from the past, and he can achieve twice the result with half the effort in the practice of the ninjutsu he has learned, the Uzumaki clan's fuinjutsu is not so easy to master. But if it can be practiced, it will also increase his combat power. In the ninja world, many people think that Fuinjutsu is not worth learning and are not very useful in battle. This is absolutely a prejudice. Only those who have really come into contact with powerful Fuinjutsu will know how terrible this jutsu is. There are barrier Fuinjutsu that can create a prison-like barrier out of thin air, chakra sealing, etc. However, since the demise of the Uzumaki clan, ninjas who use Fuinjutsu have almost disappeared. Even if he had mastered the Uzumaki clan's Fuinjutsu, he didn't use them that often in battle.
Before Minato's death, the only ninjas who had fought with him and were still alive were the A and B brothers of Kumogakure and the masked man who controlled the Nine-Tails to attack Konoha. As for the other major ninja countries, they don't have many Fuinjutsu, but in front of the Uzumaki clan's Fuinjutsu, they are just fireflies competing with the bright moon. The two are completely incomparable.
In order to see the Nine-Tails in the depths of the spiritual space again and determine what advantages and disadvantages its chakra has for him, Minato began to practice day and night. In this way, half a month passed quietly. In the past half month, Minato almost never left the house, only occasionally going outside to replenish food and necessities. Although he promised Jiraiya not to push too much, for Minato who had regained his memory, there was not much time left. Moreover, because of the Nine-Tails Chakra, his body was different from ordinary people, and his recovery and endurance were extremely amazing. This situation became more obvious as he grew older.
In Minato's room, two of Minato stood opposite each other. One of the "Minato" formed a seal with both hands and then slapped the Minato opposite. Suddenly, the black chakra array permeated his body, and the chakra in Minato's body gradually quieted down. "Bang!" And the Minato who cast the chakra seal also disappeared directly, it was a shadow clone. Minato immediately closed his eyes, relying on his understanding of the fuinjutsu, he tried to calm his mind and enter the deep spiritual space. However, about half a minute later, he opened his eyes again because he felt that the chakra that was sealed in his body had been fully restored.
This was the method Minato had found in the past few days. He spent half a month and barely mastered all the selected Fuinjutsu. First, use the shadow clone to seal his own chakra, so that he can really concentrate on finding a deeper spiritual space in the sealed body. But even if he gave up struggling, with the ability of the shadow clone, he could only seal his own chakra for half a minute at most. If he used force, he couldn't even last for a few seconds. This was already a very abnormal effect. If a ninja's chakra was sealed by the opponent for a few seconds in battle, it was almost a death sentence.
Minato was not discouraged. After all, this was only the first attempt. He formed a cross seal with his hands and summoned another shadow clone again, and then continued. After that, he failed again, so Minato fell into a cycle. After three times, Minato had already found that the separated shadow clones were no longer enough to seal the chakra of the original body. So he stopped temporarily and began to refine chakra. About four hours later, it was late at night, and Minato started practicing again. His recovery ability was amazing. It only took him the same amount of time as an ordinary ninja to refine the consumed chakra.
This cycle repeated itself. On the first day, the second day, and the third day, Minato kept doing this, constantly searching, exhausting chakra, and then recovering. More than half of the vacation he asked for from Sandaime had passed, and Kushina's monitoring time should be coming to an end. She must have had a hard time during this period. She seemed carefree on the surface, but she was actually a very thoughtful girl who cared about other people's evaluations of herself. Becoming the Nine-Tails Jinchūriki meant loneliness, and Minato would try to help her completely resolve this loneliness before the Ninja World War began. He would not let her suffer any more harm, whether from the village or from the outside world. He would block the wind and rain for her.
When Minato sealed himself again, he quickly entered a state of concentration. After a few days of familiarity, he was already familiar with it. Finally, this time he did not exit directly from this state. The spirit sank into the body, as if merging into the ethereal nothingness. A cold and chilly feeling appeared in the consciousness. "Success!"
