I became Naruto Uzumaki's younger sister

The next day, Naruko, who was delivering food to the Sandaime, was asked by him to have dinner with him. Naruko had no choice but to deliver food to Naruto later, and first spend time with the grandfather in front of her.

"Naruko, I heard from Kai that you want to exercise?" The Sandaime spoke slowly and leisurely.

Naruko nodded: "Yes, your body is too fragile and you really need to exercise, otherwise you won't be able to become a powerful ninja. And Mr. Kai is a fitness guru at first glance, and he will definitely be able to give good advice."

The Sandaime touched Naruko's head: "Naruko, it's good that you have this idea, but he is very busy. He has a mission for half a month now, and he often encounters it, which is not good."

Naruko heard something unspoken and complied: "Then what should I do, Grandpa?"

The Sandaime laughed: "Haha, your grandfather and I are also the Sandaime Hokage after all, so I can teach you more than enough."

Naruko's eyes lit up, this was a good opportunity.

In the original work, the Sandaime Hokage was called the strongest Hokage, which was fine in the early stage, but later after seeing Hashirama, many fans made fun of him because of the huge gap.

In fact, Sarutobi Hiruzen is also very powerful. Known as the Doctor of Ninjutsu, he can use all attributes to the extreme of ordinary people. He mainly uses physical skills and supplements with experience, making him a proper pentagonal warrior.

Moreover, the Nidaime had just died at that time, and he was a newcomer as Hokage. He only had brothers like Danzo under his command, and the other Ninja countries were eyeing him. If he didn't raise the banner, how could he stabilize the situation?It was just a forced move to spread the name of the strongest ninja. At that time, the Uzumaki clan was destroyed and Konoha was unable to support it. It can be seen that the situation was serious.

"Grandpa, is it true?" Naruko asked happily.

Sarutobi Hiruzen was amused by her tone and happy look: "Hehehe, yes, grandpa will help you with physical exercise from now on."

Naruko jumped up for joy: "Okay, the Sandaime Hokage will teach me ninjutsu." Naruko thought about it and started talking nonsense.

Sarutobi Hiruzen didn't care too much. It was a joke. Could it be that a great ninjutsu doctor couldn't teach a child?

In this way, Sarutobi Hiruzen took the time to teach Naruko that afternoon, and the two began at an ANBU private training ground in Konoha.

Sarutobi Hiruzen looked down at Naruko and asked, "Naruko, you said it yourself, a powerful ninja needs a good body. So tell me what aspect you need to train most now?"

Naruko thought for a moment and said, "Calmness and reflexes."

Sarutobi Hiruzen's cheerful expression changed slightly, and then he looked at Naruko with appreciative eyes: "Yes, this is indeed what is needed most."

"But calmness requires the accumulation of time and the training between life and death countless times. In short, you have to survive first."

"Yes!" Naruko nodded.

"So while you are improving your body, you need to strengthen your reflexes and teleportation skills so that you can judge the situation and escape danger as quickly as possible in a battle."

"I'll let someone tell you the assessment I've set later. Just follow it first, and grandpa will make a plan for you based on the assessment. By the way, if you can't stand it, you can stop. Don't force yourself. Grandpa only wants you. happy."

Naruko looked at him: "Grandpa, I will definitely finish it."

Sarutobi Hiruzen smiled and touched Naruko: "Okay, grandpa will wait for you to finish." Then he left.

Naruko looked around curiously, this must be the forest of death, right?I didn't even notice it just now.

A figure suddenly appeared in front of Naruko. Naruko saw that she was a beautiful woman with purple hair, a delicate face, and a slender figure.

"Miss Naruko, I am Uzuki Xiyan, your instructor." Uzuki Xiyan said expressionlessly.

Naruko felt like she had seen it before, but she really didn't remember it: "Hello, Sister Xiyan."

A smile appeared on Maoyue Xiyan's iceberg-like face: "Then you start. First, run as fast as you can in the training ground. Stop if you can't hold on."

"So fierce from the beginning?" But he didn't think too much about it. This performance is related to the Sandaime's training on himself, so he must do it well!

Naruko ran quickly in the training ground. She had never learned how to run as a ninja, so she did not force herself. She still ran like in her previous life, relying on her left and right hands to balance her body and running as fast as flying.

But after a while, Naruko began to feel tired, her body was heavy and her muscles were tired.If you don't know how to use chakra, you can only be like ordinary people.

But slowly, Naruko felt the chakra in her body surge into her limbs, relieving muscle fatigue and restoring her strength.

"Is this the effect of my whirlpool constitution? Well, I must have passed the test." Naruko thought to herself.

Uzuki Xiyan was also surprised by Naruko's endurance, and stopped her when Naruko ran for an hour: "Naruko, stop."

When Naruko heard the stop, she actually felt very relaxed and still had a lot of chakra.In front of Mao Yue Xiyan who left, he looked up at her.

"Have you just realized how to use chakra to help you run?"

Naruko nodded: "Yes, sister."

"Do you need a rest?" Xi Yan asked with concern.

Naruko shook her head. The sweating was just the result of only using her body at the beginning. Later, her body was repaired by chakra, and the fatigue was quickly eliminated.

Xi Yan did not force the request: "Then start the next test."

The two of them came to several stone locks. Xiyan pointed at the stone locks and said, "The weight ranges from 50 pounds to 200 pounds. You try your best to show your strength."

Naruko came to the stone lock and tried the 50-jin stone lock first. She did not use chakra, so it was difficult to lift it up and put it down. Then she tried the 52-jin stone lock. With both hands, it stopped working after just lifting it a little.Being able to lift even a little bit is a credit to Uzumaki's physique, which makes Naruko feel like she is born with supernatural powers. You must know that Naruko, who is only five years old this year, only weighs [-] pounds.

lay down.Using chakra, he lifted the hundred-jin stone lock, and now there was no problem.

Challenging the 150-pound stone lock, with the help of chakra and whirlpool physique, this was accomplished.

But when lifting the 200-pound stone lock, the feeling of limit came again. Chakra greatly improved strength, but what limited Naruko was her weight and experience. No matter how hard Naruko exerted herself, she felt weak. She looked at Xi Yan , Xi Yan's eyes were very dull, and it seemed that she had not achieved a very satisfactory result.

Little did Naruko know that when she lifted the 150-pound stone lock, Xiyan was already surprised. She didn't have such strength when she was 5 years old.She quickly regained her expression from her long-term iceberg face, which caused Naruko's misunderstanding.
