Body Technique: Instantaneous Movement

The sunlight at dusk spilled across the earth, and a clear river flowed slowly through the light, its babbling sound echoing through the woods.

Standing in the clearing beside the river, Shisui Uchiha took a black belt with a special seal from his storage scroll and handed it to Lin Feng.

"Why is it so heavy?"

The moment he took the belt, Lin Feng instantly felt that it was far from ordinary.

Unlike a standard belt, he estimated this one weighed at least ten pounds.

"Why don't you put it on first?"

Seeing the expression on Lin Feng's face, Shisui Uchiha suddenly smiled.

"Alright!"

Sensing that this belt was surely related to his upcoming training, Lin Feng did not hesitate and fastened it directly around his waist.

"Body Flicker techniques are generally practiced through high-speed running and rapid jumping, but to achieve better results, one must rely on ninja tools for training."

"The belt you are wearing now is a ninja tool that can adjust its weight. It is currently set to five kilograms, and the weight will continue to increase later on."

After Lin Feng had secured the belt, Shisui Uchiha explained.

Weight-bearing training is quite grueling in the beginning because people are accustomed to the weight of their own bodies; once weighted down, one feels resistance in every action, much like walking against a strong current, which is particularly uncomfortable.

However, after adapting for a period of time, this sense of resistance gradually fades, replaced by indescribable benefits. The moment a ninja removes the weights during combat, their body instantly becomes incredibly light, allowing their speed to reach its absolute limit. Even performing a Body Flicker would become an effortless task.

"This is truly a great method!"

After hearing Shisui Uchiha's explanation, Lin Feng praised it highly.

"Alright Sasuke, let's begin your training!"

"Run from here to that large rock ahead—a distance of about one hundred meters—and complete it in five seconds!"

Pointing to a large rock in front of Lin Feng, Shisui Uchiha instructed.

"No problem!"

Nodding, Lin Feng stomped his foot and his figure immediately dashed toward the rock.

"Time: twelve seconds!"

Although Lin Feng had put in his best effort, the sudden increase in body weight still impacted his running speed. As soon as Lin Feng reached the side of the rock, Shisui Uchiha immediately called out the result.

"Shisui, again!"

Lin Feng was naturally unsatisfied with this result. Clenching his fists, he surged out from beside the rock, preparing to return to his starting position.

"Time: thirteen seconds!"

"Sasuke, you have to keep it up!"

With his stamina being drained, Lin Feng's return time was even longer than the first.

"Heh, I won't admit defeat so easily. Again!"

After catching his breath, Lin Feng began to run once more under the watchful gaze of Shisui Uchiha.

"Time: fourteen seconds!"

"Time: fifteen seconds!"

"Time: eighteen seconds!"

As the sky gradually darkened, after running back and forth dozens of times, Lin Feng finally reached his physical limit and collapsed to the ground. He gasped for air like a windmill, and sweat poured rapidly down his forehead.

"Sasuke, today's training ends here. You did very well!"

Walking over to Lin Feng's side and observing his exhausted state, Shisui Uchiha smiled.

"I think my performance today was terrible. I hope to do better next time!" Taking a few heavy breaths, Lin Feng's voice sounded somewhat hoarse from extreme exhaustion.

"Heh, I was even worse than you when I first practiced this!"

Patting Lin Feng on the shoulder, Shisui Uchiha grinned.

"Thank you, Shisui!"

Hearing that Shisui Uchiha was comforting him, Lin Feng expressed his gratitude.

"Get some good rest, and we'll continue tomorrow!"

The effort and character Lin Feng displayed made Shisui Uchiha particularly fond of him, and naturally, he wanted to guide this younger clansman well.

"Mm!"

Pushing himself up from the ground and taking heavy steps once more, Lin Feng and Shisui Uchiha walked toward the nearby Uchiha Clan compound, chatting and laughing as they went.

In the pitch-black night sky, a bright moon hung dazzlingly, casting silver moonlight across the earth.

After finishing dinner and taking a short rest, Lin Feng pulled Itachi into the courtyard to practice the Shadow Clone Technique, which he had yet to master.

Although Itachi had explained the key points of the Shadow Clone Technique the previous night, he went over them once more to prevent Lin Feng from making any mistakes. After all, the Shadow Clone Technique was considered a forbidden jutsu; if the user distributed too much chakra, it could become life-threatening.

"Shadow Clone Technique!"

Following Itachi's instructions, Lin Feng formed the hand seals, attempting to summon a shadow clone.

"Poof!"

With a soft sound, a puff of white smoke rose beside Lin Feng. As the mist cleared, a listless, trembling shadow clone appeared.

"I'll try again. Shadow Clone Technique!"

Anxious, Lin Feng tried once more, but the result was identical to the last.

Refusing to give up, Lin Feng continued, but the string of failures caused his composure to shatter.

"Brother, I really am useless!"

Punching his pathetic shadow clone into nothingness, Lin Feng complained.

Although the shadow clone before him was much stronger than the one from last night, it possessed zero combat capability, and Lin Feng was far from satisfied.

"Sasuke, learning ninjutsu must be done step by step. You only started practicing last night; to reach this level already is quite impressive."

Watching his younger brother's dejected expression, Itachi hurried to comfort him.

"Brother, I know about taking things step by step, but I have too many things to do. I simply don't have time to waste."

Thinking of how Danzo would move against Shisui Uchiha in six months, Lin Feng knew he had to improve his strength as quickly as possible.

Habitually tapping Lin Feng on the forehead with his finger, Itachi chuckled softly, "Sasuke, at your age, you shouldn't have so many worries!"

"Brother, I..."

Lin Feng wanted to say something more, but Itachi cut him off.

"Little brother, no matter what difficulties you encounter in the future, I will always protect you!"

"For now, I only hope that you can grow up happily!"

Itachi's heartfelt words instantly brought to mind the lines from the Naruto plot that Obito had once said to Sasuke.

He killed his clan, killed his parents, killed his lover, and left only you behind—his beloved younger brother!

In your brother's heart, your life is more important than the safety of the village!

"Brother, I will definitely work hard on my training. I won't let you bear the pain alone!"

Truly feeling the love Itachi held for his brother, Lin Feng couldn't help but hug Itachi tightly, his voice hoarse yet firm.

In that moment, Lin Feng made a resolution: even if he died in the Naruto world, he would change Itachi's tragic fate.

"Sasuke, then let's continue the training!"

Though he didn't understand the meaning behind Lin Feng's last sentence, Itachi stroked Lin Feng's forehead and smiled.

"Mn!"

Nodding, Lin Feng felt his frustration and manic mood vanish. No matter how many times he failed, he patiently practiced the Shadow Clone Technique throughout the entire night.
