After Uchiha Yukio joined, Uchiha Mukaku's training plan became more refined. To support his son's ideals, Uchiha Yukio would also accompany him during his free time to exercise together.
One morning a year later, Uchiha Mukaku finished his last physical training for the day and was resting with his hands on his knees. Suddenly, a bottle of water appeared in his vision.
He looked up in surprise and saw a confident, sunny smiling face. The other person had neat, short hair, and his gentle, charming peach blossom eyes turned crescent-shaped when he smiled. The only slight flaw was his cute button nose, which, while weakening his aggressiveness, was a minor regret for Uchiha Mukaku, who preferred a high nose bridge.
Although this person was smiling brightly, Uchiha Mukaku did not recognize him. Just as his mind was full of questions, the other person's voice rang out again: "Didn't Uncle Yukio accompany you for training today? My name is Uchiha Shisui. Here, drink some water!"
Uchiha Mukaku did not refuse the kind offer, but merely reminded him: "You should know that I am Uchiha Setsuna's grandson. If you get too close to me, you might be targeted!"
The other person responded without changing his expression: "I am Uchiha Kagami's grandson, so we can be considered to be in the same boat!"
Hearing the other person's reply, Uchiha Mukaku nodded thoughtfully. Uchiha Kagami's lineage was also not well-regarded within the Uchiha Clan; after all, he was the Second Hokage's disciple, which in the eyes of many Uchiha Clan members was undoubtedly blatant betrayal.
Uchiha Mukaku took the water offered to him, drank it all in one gulp, then wiped his mouth and asked, "What do you want from me?"
The other person still had a sunny, cheerful smile on his face and replied, "I just want to be friends with you!"
Uchiha Mukaku looked at Uchiha Shisui, who was 10 centimeters taller than him, and said with a somewhat smug expression, "Then we're friends from now on. See you another day!"
As soon as he finished speaking, he turned and left without hesitation, vaguely hearing the other person's "goodbye" in his ears.
On the way home, Uchiha Mukaku was a little confused, not understanding why Uchiha Shisui would target him. At his current age, he shouldn't be involved in schemes yet.
(PS: The original work does not provide Uchiha Shisui's age. However, given that Uchiha Shisui earned the title "Shunshin Shisui" during the Third Shinobi World War, this indicates that he was already a powerful and well-known force in the Ninja World at that time. Kakashi Hatake became the youngest Jonin in Konoha Ninja Village at the age of 12, which happened to be the end of the Third Shinobi World War. From this, it can be inferred that Uchiha Shisui should be at least the same age as Kakashi Hatake, or even older. But there is a contradiction here: Uchiha Shisui is a few years older than Uchiha Itachi. In the original work, when Uchiha Itachi entered the Ninja Academy at age 6, Uchiha Shisui was already an excellent Ninja, probably 5-8 years older than Uchiha Itachi. Combining these two aspects, we set Uchiha Shisui and Kakashi Hatake to be the same age. Explanation concluded.)
Uchiha Mukaku returned home, showered, and then arrived punctually at the dining table already filled with breakfast. Just as he was about to start eating, his father, Uchiha Yukio, suddenly spoke.
"Ninja Academy is starting in two days. I've already signed you up."
This made Uchiha Mukaku slightly stunned. To achieve his goal of making Kakashi Hatake his stepping stone, he had originally planned to ask his father to send him to the Ninja Academy in a couple of days. He hadn't expected his father to bring it up first.
Hearing this news, he responded with joy, "I understand!"
Looking at the child's excited expression, an ominous feeling welled up in Uchiha Yukio's heart. This boy usually acted so mature; for him to be so excited today, he must be up to something!
However, Uchiha Yukio was determined to let this child make some friends, so even with a bad premonition, he forced himself to suppress it. He only hoped that this child would grow up healthy and strong.
Uchiha Mukaku devoured his breakfast like a whirlwind and said to his father, who was washing dishes, "I'm going to school now. You'll be an empty-nester soon, it's time to consider your life partner."
Hearing this, Uchiha Yukio's heart was filled with relief, but he laughingly scolded, "You stinky brat, your feathers haven't even grown in yet. Mind your own business and go practice properly."
Uchiha Mukaku pouted helplessly. This guy was clearly happy inside, but still had to scold him. He replied perfunctorily, "Got it, I'm going to practice Shuriken now." With that, he vanished from the living room in a flash.
Arriving at the Uchiha Clan's specially designated training ground, Uchiha Mukaku immediately spotted Uchiha Shisui, who had given him water that morning. He strode over to him, stretching his body as he asked, "I really didn't expect you to be here too?"
Shisui looked at the overly familiar Uchiha Mukaku and replied with a smile, "I heard you often practice Shuriken here, so I specifically came here to wait for you."
Looking at Shisui's smiling face, Uchiha Mukaku paused slightly, then sincerely said, "From now on, we can train together."
"Alright, it's a deal!" Uchiha Shisui replied readily and happily.
As Uchiha Mukaku spoke, he took out his training Shuriken and kunai. These tools were identical to those used in actual combat, except they were not sharpened to avoid injury.
Seeing Uchiha Mukaku take out his training equipment, Uchiha Shisui stopped talking and stood aside to watch Mukaku train.
The Uchiha Clan's Shuriken throwing technique is extremely flashy. With their excellent dynamic vision, they can make Shuriken collide in mid-air, allowing them to hit blind spots that ordinary throwing methods cannot reach.
Uchiha Mukaku was practicing this technique today. But before starting, he first got a feel for it. He spread his palm, and three Shuriken suddenly appeared in his hand as if by magic.
With a flick of his wrist, the three Shuriken cut through the air and flew out, accurately hitting the center of the target twenty meters away.
Even though the Shuriken were not sharpened, under Uchiha Mukaku's powerful force, they still deeply embedded themselves into the practice target, penetrating three fen deep.
This was not all; Uchiha Mukaku continued to train. He first threw three Shuriken at a specific angle, then immediately threw two more in the blink of an eye. After a brief collision, the three Shuriken simultaneously and accurately hit the bullseye on the opposite target again.
An expert sees the way, a layman sees the excitement. Uchiha Shisui saw the other person's training and knew that his Shuriken throwing technique had already reached a high level. Although the other person seemed to only use his wrist when throwing, in reality, his fingers, wrist, arm, and shoulder were all exerting force. Otherwise, it would be impossible to maintain such accuracy and power while keeping a stable trajectory.
