Naruto: They Have Systems

Uchiha Yin had always considered the Substitution Technique an extremely useful jutsu. He had studied it in depth, and his Hand Seals were lightning-fast.

Minato Namikaze could not form Hand Seals nearly as quickly. With Uchiha Yin charging at him from behind, Minato barely managed to turn around and retreat a few steps before raising both hands to block the attack.

Thud!

A heavy punch slammed into Minato's hands.

Uchiha Yin had held nothing back. He had put all his strength into that punch.

He had also discovered that after the system had cleansed and strengthened his body, on top of his earlier physical gains, he possessed strength beyond that of an ordinary adult despite his young age.

The cannonball-like punch sent Minato flying and crashing to the ground.

Tsunade's eyes lit up. This kind of hard-hitting fighting style was exactly to her taste.

Uchiha Yin did not stop after that blow. He clenched his fist and charged at Minato again.

Minato's hands ached as though a truck had run them over. He tried to form Hand Seals, but the pain slowed him down. Before he could finish, Uchiha Yin's fist was already in front of his face.

"You lost."

Uchiha Yin spoke calmly.

"Yeah, I lost. I didn't expect you to be this strong, Yin."

Minato gave a rueful smile.

He had expected Uchiha Yin to be strong, but not strong enough to defeat him with Taijutsu alone.

Only after facing Uchiha Yin himself did he understand just how strong he was.

"But one day, I'll surpass you. My goal is to become Hokage."

Minato said it with a radiant smile.

The fight had been quick and ended so suddenly that it was over before anyone could react.

"No way. Minato Namikaze, that genius, went down that easily?"

"Maybe he underestimated Yin?"

"How could that be? Uchiha Yin was clearly just too strong!"

"Yeah, this is ridiculous. He couldn't even beat me before."

"Maybe he just didn't want to show what he could really do. He probably went all out today because Lady Tsunade and the others were here."

The students all talked over one another, filling the training ground with noise.

Kushina Uzumaki walked over to Uchiha Yin and congratulated him happily. "Congratulations, Yin! I knew you could beat that pretty boy."

Her eyes narrowed into happy crescents. Uchiha Yin's victory delighted her more than anyone else, even more than a victory of her own would have.

"Thanks."

Uchiha Yin smiled and smoothed Kushina's hair.

Kushina did not pull away. Her cheeks flushed faintly as she enjoyed his touch.
