The man standing at the top of the ninja world

"What, S-level ninjutsu?" Nagato was startled when he heard this, and then looked at Uzumaki Mito in surprise, "Grandma Mito, are you kidding me?"

"Of course it's not a joke." Uzumaki Mito said with a smile on his face: "Nagato, didn't you tell me before that you wanted to learn new ninjutsu?"

Nagato replied hesitantly: "I said so, but Grandma Mito, didn't you agree at the time?"

Two and a half years ago, after formulating a plan to quickly learn ninjutsu using the art of multiple shadow clones, Nagato set a goal for himself. He would rely on a hundred shadow clones to destroy Konoha as quickly as possible. Learn all the official ninjutsu in one fell swoop.

A month ago, he successfully practiced the last B-level ninjutsu given to him by Nagato Uzumaki Mito. So far, he has the official collection of Konoha's official collection of ninjutsu below A-level, including e, d, c, b, etc. Having learned all of them, and the total number of these ninjutsu is in the thousands, it can be said that Nagato is now the person who masters the largest number of ninjutsu in the entire ninja world.

Of course, after learning all the B-level ninjutsu, he made a request to Uzumaki Mito to learn A-level ninjutsu, but was rejected by Uzumaki Mito on the grounds that the ninjutsu he had learned now was too powerful. Too much, and he is too young. He should calm down and review the ninjutsu he has already learned, instead of rushing to learn new ninjutsu.

As a result, it was only a month later that Uzumaki Mito suddenly wanted to teach him a new ninjutsu, and it was not the A-level ninjutsu he originally requested, but the most advanced S-level ninjutsu. Nagato had to let this go surprise.

Uzumaki Mito nodded gently and explained: "Nagato, a month has passed since the last time you made a request. I think you should have reviewed the ninjutsu you learned before."

"Furthermore, this S-level ninjutsu is different from other ninjutsu. It is very suitable for you. At the same time, its training process is also very cumbersome. It requires a lot of time and perseverance to practice successfully, so I think it should I’ll teach you this technique as soon as possible.”

"From now on, you can practice this jutsu while reviewing the ninjutsu you learned before."

It suits me well and takes a lot of time to practice.

The S-level ninjutsu possessed by Konoha Village emerged in Nagato's mind one by one, but he was too lazy to guess. He blinked and asked directly: "Grandma Mito, what kind of S-level ninjutsu are you going to teach me?"

"Nagato." Uzumaki Mito said slowly, "The S-level ninjutsu I want to teach you is called Yin Seal."

"Yin Seal." Nagato read these three words again, and the specific information of this move was quickly recalled in his mind.

This is an auxiliary S-level ninjutsu. Its function is very simple. It allows the caster to store a large amount of chakra. In the original book of Naruto, there are three people who know this trick, namely Uzumaki Mito, Tsunade, As well as Sakura, the biggest feature of the Yin Seal is, or the most obvious sign is that after successful training, a purple diamond-shaped mark will appear on the forehead.

However, although Nagato had long known the specific function of the Yin Seal, on the surface, he still pretended to know nothing and looked at Uzumaki Mito, and asked with a blank expression: "The name Yin Seal is , Grandma Mito, do you want to teach me the sealing technique?"

"That's not the case." Uzumaki Mito explained: "Nagato, you misunderstood. Although the name of the Yin Seal contains the word seal, it has nothing to do with the sealing technique. It is an auxiliary ninjutsu. "

"Auxiliary Ninjutsu"

"Yes, Nagato, the amount of chakra of each ninja is limited. In battle, there will often be insufficient chakra. Although the amount of chakra of our Uzumaki clan is far higher than that of ordinary people, we are no exception. I It is based on this that the Yin Seal was created, and the function of the Yin Seal is to store a large amount of additional chakra for the caster in daily life."

"In this way, when you exhaust the original chakra in your body during the battle, you can extract the pre-stored chakra from the Yin Seal and restore your chakra to its intact state."

"It's so powerful. In this way, when the enemy's chakra is exhausted, the ninja who learned the Yin Seal can still maintain the peak chakra level." Nagato said with a look of amazement on his face: "Grandma Mito, can You are truly amazing for developing such a powerful ninjutsu.”

"Haha." Uzumaki Mito smiled and said, "Nagato, listen to me first. Although the Yin Seal is very practical, it also has great limitations."

"The biggest disadvantage of the Yin Seal is that its cultivation process is very long and requires you to accumulate a certain amount of chakra every day and store it in the Yin Seal. However, these accumulated chakra cannot be used until you have successfully cultivated it completely. "

"Nagato." Uzumaki Mito stretched out a finger, pointed at the purple diamond-shaped mark on his forehead, and said, "Did you see this purple mark? The chakra accumulated in the Yin Seal is stored in this mark. Yes, when you successfully learn the Yin Seal and fill up the space for storing chakra, a purple mark like this will appear on your forehead, which is a sign of successful Yin Seal cultivation."

"In other words, only after such a mark appears on your forehead can you use the chakra previously accumulated in it."

"And this process is very long. Even with your talent, it will take at least several years to succeed."

"After you successfully practice the Yin Seal, you can freely extract the chakra in the mark. On the other hand, after you use up the stored chakra, the space in the mark will be empty, and you need to fill it up again. Only then can it be used a second time.”

"But this is nothing. After you succeed in practicing, it will be much easier to fill it up for the second and third time. You can complete it easily."

"Grandma Mito, I understand." After listening to Uzumaki Mito's words, Nagato nodded seriously.

Immediately, a trace of doubt rose on his face, and he asked: "But, Grandma Mito, since the Yin Seal is so powerful, why did you only teach me one person? Yahiko, Kushina, and Konan should be allowed to Let’s practice this technique together.”

Uzumaki Mito smiled and shook his head, and then said: "Nagato, your idea is good, but it is not realistic. The reason why I only taught you the Yin Seal is because between you, Kushina, and Yahiko, Among the four Xiaonan, you are the only one who can practice this technique."
