Time flew by.
During this period, Hyuga Yuto had adapted to his new identity. As a disciple of one of the Sannin, he received far more attention than before.
Except for returning to the Hyuga clan at night, he spent most of his day at the Senju clan grounds, either practicing medical ninjutsu and Monstrous Strength taught by Tsunade or studying medical books.
Due to teaching Hyuga Yuto, Tsunade temporarily ended her wandering life and moved into the Senju clan grounds with Shizune. She was too lazy to manage Konoha's affairs and only focused on teaching Hyuga Yuto on a daily basis.
Shizune was one year younger than Hyuga Yuto, the same age as Kakashi, and still an eleven-year-old little girl, far from the gentle and virtuous image she would have later in the manga's main plot.
At first, the little girl was quite hostile towards Hyuga Yuto. This was probably a childish jealousy, feeling that this guy without black eyeballs had stolen Master Tsunade's attention.
However, this small hostility only lasted for less than a day. Having been bombarded by short videos from another world, Hyuga Yuto was a master of coaxing girls. With a little effort, he made the little girl laugh, calling him "My good junior brother" and happily going to buy fish.
– Beginners in medical ninjutsu often use various small animals for experiments. Fish are the choice of most beginners. This ancient vertebrate has a fairly simple structure, making it suitable for practice. More importantly, even if medical ninjutsu fails and messes up the fish's body, it can still be used to make fish soup, which is not a waste.
Medical ninjutsu doesn't sound "cool," but only those who actually practice it know that it is a ninjutsu that tests chakra control to the extreme. When inputting chakra, even a slight increase in force can cause necrosis of the recipient's nerves and muscles.
This is quite similar to the practice of Monstrous Strength. The same ninjutsu, in the hands of some people, can only split bricks and tree trunks, but strong people like Tsunade can use "Monstrous Strength" to split mountains and rocks.
Both require a high degree of precision in chakra manipulation, and the practice of Monstrous Strength and medical ninjutsu complement each other.
In the morning, he practiced medical ninjutsu, and in the afternoon, he honed his Monstrous Strength. Tsunade would often come to teach medical knowledge. Everything was proceeding in an orderly manner.
The only thing that stalled was the development of "Lion's Fangs."
The concept of this technique was very lofty. When Hyuga Yuto first conceived it, he thought of "combining the Gentle Fist routines with the Rasengan's chakra-releasing technique to embed a solid chakra shell outside the palm, making up for his lack of offensive power."
Simply put, it was a smaller and simplified version of "Susanoo," covering the hand, specifically for use with the Byakugan.
However, the idea was beautiful, but the execution was very difficult.
Fixing the "shape" of the chakra, increasing its "hardness" without losing its flexibility, maintaining offensiveness without harming oneself...
Each problem was a hurdle, but fortunately, Hyuga Yuto made a good start by shaping it first.
In the second month after becoming Tsunade's disciple, Hyuga Yuto could already extract and reinsert the spine of a fish. After releasing it, the fish would be alive and kicking, and the soup made from it would be particularly delicious.
In terms of Monstrous Strength, due to his training in the Gentle Fist from a young age, Hyuga Yuto's acceptance of this technique was high, and his progress was rapid. He could already shatter rocks the size of an adult with one punch. When used in conjunction with the Gentle Fist, the alternating bursts of hard and soft power greatly increased his combat power.
However, the progress of "Lion's Fangs" was minimal.
Tsunade was also quite frustrated with this problem. She was a master of medical ninjutsu, but she didn't know much about the chakra field. Making energy into incredibly hard armor was almost beyond her ability.
Helplessly, Tsunade could only take Hyuga Yuto to find Minato Namikaze.
To some extent, the Rasengan could be considered "flowing armor." as it involves rapidly rotating chakra that forms a protective sphere around the user's hand.
Minato Namikaze's greatest talent lay in his "reflexes" and "spatial awareness," and besides that, he also had a good understanding of changes in chakra nature.
Minato Namikaze naturally didn't refuse. Officially, Tsunade was one of the Sannin, whose status was higher than his. Privately, she was a comrade who had fought alongside his teacher. Minato Namikaze had no reason not to help.
The Yellow Flash was indeed a very outstanding ninja, and he was also very good at dealing with people. He took some time to study with Hyuga Yuto in depth.
"Yuto-kun, to put it bluntly, I think you might be overthinking it."
"I don't know where you got this idea from, but... why turn chakra into armor?"
"Chakra is energy, it is wind, lightning, water... It flows."
"From a microscopic perspective, including time, everything is in motion. Turning chakra into armor is like killing it. Yuto-kun, I think you should..."
Minato Namikaze's words greatly inspired Hyuga Yuto, and he immediately realized that he was indeed overthinking it.
– When he watched the manga and TV series in his previous life, Susanoo left a deep impression on him, which influenced his thinking.
After Minato Namikaze cleared the clouds, the development of "Lion's Fangs" also had a new direction.
Medical ninjutsu and medical knowledge, Monstrous Strength, and the development of new ninjutsu were all on track. Hyuga Yuto spent more and more time at the Senju clan grounds, and there were many times when he simply didn't go back and slept directly in the room next to Tsunade.
Just like that, three whole months passed since he became Tsunade's disciple.
The ninja world entered winter.
The cold wind howled, and everything was covered in silver.
During the time Hyuga Yuto was immersed in training, many things happened in the outside world.
The friction between the Five Great Nations became more and more serious, and everyone could smell the smoke of war. After a major battle with the Cloud Village's A and B brothers, Minato Namikaze retreated safely and gained great fame. The wife of the Uchiha clan leader, Uchiha Mikoto, gave birth to a healthy boy more than a month ago, named Uchiha Itachi...
The times were quietly changing, but no one knew it yet – except for Hyuga Yuto.
On this day, Hyuga Yuto took a break from three months of intense training. He found Tsunade and prepared to leave for a while.
The reason was simple, so simple that Tsunade couldn't refuse.
"Teacher, as a Konoha ninja, I've been holed up in the village for three months. Only now, when I came out, did I realize that the year is almost over. I should also take on some missions and get some fresh air... There's no such thing as becoming a strong person by just training."
Bidding farewell to Tsunade, Hyuga Yuto left the Senju clan grounds.
It was very cold outside, and the snow was thick.
Hyuga Yuto looked at the village decorated with snowflakes and then at himself, feeling that many things had changed, but some things had not changed at all.
– The Caged Bird was still engraved on his head.
Becoming Tsunade's disciple didn't bring him true satisfaction.
The Branch Family boy glanced at the Hyuga clan grounds in the distance and turned back indifferently.
It's time to do some real work, he thought.
