"Shiro! You're here!" Uchiha Sasuke, full of joy, ran over upon seeing Shiro's arrival.

Seeing Sasuke, Shiro quickly brushed aside his idle thoughts.

"That's right, I promised to guide your training today!"

"Great!" Sasuke's face lit up with excitement.

At the same age, Sasuke didn't believe Shiro trained more than he did. 

However, the gap in their strength was enormous—there had to be some special training technique! 

Yet, if Sasuke knew that Shiro's strength had nothing to do with training, he might just lose his mind...

Shiro, deep in thought, walked to the lake. After glancing at it, his mouth began to water.

Quickly wiping it away, Shiro pointed at the fish in the lake and laughed, "Today's training task is simple. Catch a fish in the lake without using your Sharingan!"

"You just want to eat fish, don't you?"

Shiro coughed awkwardly, then sternly replied, "You don't understand! The thought of revenge has been weighing on your mind, making you eager to grow stronger, but you haven't built a solid foundation! Walking on water will help you train your chakra control, just like walking on trees!"

Sasuke hesitated, then looked at Shiro apologetically, "You've been so diligent in teaching me, and yet I misunderstood you."

Shiro smiled and quickly waved his hands. 

"It's fine, we're not children anymore. No need to worry about such things! Now, start training, I'll go gather some firewood!"

Sasuke slowly walked to the lake's edge. With gritted teeth, he stepped onto the water.

As soon as his foot touched the surface, it sank slightly, but he managed to stand. 

He placed his other foot onto the water, and though both feet were submerged to his ankles, he was standing—though wobbling like he was on a giant pudding. After taking a few shaky steps, Sasuke gradually became more stable.

However, today's task wasn't just about walking on water—he still had to catch a fish!

A fish swam nearby, and Sasuke seized the opportunity, reaching for it. The fish darted away in fear, and Sasuke, losing focus, fell into the water.

"Damn! Why is this so hard?! Again!"

Shiro returned with an armful of dry firewood, seeing Sasuke soaked from head to toe. However, Sasuke showed no signs of giving up, repeatedly falling and getting back up.

Shiro shook his head in resignation.

Sasuke wasn't the prodigy people said he was, but once given a clear direction, he worked harder than anyone. Of course, that green-suited weirdo didn't count!

After about thirty attempts, Sasuke finally caught a small fish with one hand, running excitedly toward Shiro.

"Look! I did it!"

Shiro's mouth twitched as he looked at the fish, barely three centimeters long. "How did you catch something that small? I want big fish, not this tiny thing!"

"So, you *were* planning to eat it after all!"

Shiro coughed again, then looked at Sasuke in disappointment.

"The bigger the fish, the stronger its defenses, and the more force it takes to catch! If you can't handle a big fish, how will you ever face a ninja on water?"

Sasuke shivered, shame covering his face.

"I misunderstood you…"

"Good, now you know. I'll start the fire, and you better catch a bigger one!"

"Alright! I won't let you down!"

Sasuke returned to the lake, and after about half an hour, finally caught a fish the size of a palm. This time, without boasting, he tossed it to Shiro and continued training.

Shiro looked at the small fish with a bitter smile. He had hoped Sasuke could easily catch enough for a full fish feast, but by noon, there was still just the one small fish.

Feeling his stomach protesting, Shiro reluctantly began preparing the fish.

As the fish grilled over the fire, the delicious aroma filled the air, and Shiro, now starving, could hardly wait to stuff it into his mouth.

Suddenly, a white blur flashed by, and the fish disappeared.

"Sorry, it smelled too good, so Akamaru couldn't help himself," Kiba Inuzuka said, scratching the back of his head sheepishly.

Behind him stood Shino Aburame and Hinata Hyuga.

Hinata, seeing Sasuke standing on the lake, asked curiously, "What's Sasuke doing out there?"

Shiro, annoyed, was about to give a half-hearted reply, but then an idea struck him. He knew that more hands meant faster work, and the three in front of him were the perfect labor force!

"This is a special chakra control training method unique to the Uchiha clan. Normally, I wouldn't let anyone else see it, but since you're already here, why don't you give it a try?" Shiro said with a serious face.

"Uchiha's unique training? Can we really try it?" Hinata asked eagerly.

"Of course! Otherwise, you'll starve to death out here!" 

"What do you mean by 'starve to death'?"

Shiro coughed again and looked earnestly at Hinata. 

"When you're training alone, it's easy to slack off without competition. But if you all compete to see who catches the most or the biggest fish, the motivation kicks in. That's why teams always have three people!"

The trio suddenly understood, their faces showing excitement as they rushed to the lake.

"Wait! The fish need to be at least palm-sized! Any smaller and…" Shiro called out, but they had already dashed off.

Shiro lay back by the tree, watching them plunge into the lake one after another.

After ten tries, they could barely stand on the water. It seemed catching enough fish to satisfy their hunger would take a while.

Meanwhile, Sasuke, now more experienced, caught fish after fish, but they were all too small.

Shiro's gaze, however, was focused on Hinata...
