Naruto: Chakra System

Though Kakashi believed that Hiruzen comparing Sakura's talent with Tsunade was irrelevant. After all, who is Tsunade? Princess of the Senju Clan, granddaughter of Hashirama freaking Senju and Mito Uzumaki.

She was obviously going to have very high potential and innate talent.

Meanwhile, who is Sakura? Just a civilian kid from the Haruno family. Kakashi believed that, for someone with a civilian background, Sakura's natural talent was actually pretty high.

If Sakura had focused on training and improving herself instead of simping on Sasuke during ninja academy time, she could've been classified as a prodigy, especially in Chakra Control and Taijutsu, since normal chakra enhancement is taught in the ninja academy, and for Sakura that alone would have been quite effective even without Tsunade's chakra-enhanced Taijutsu style.

But heck, she didn't, and wasted a lot of her time, and Kakashi didn't want her to waste any more time, and started training her in the area where her strength lay, 'Medical Ninjutsu'.

3 days passed.

"Finally," Kakashi said aloud, after getting ready for the day, and looked at his system panel, the interface of his stats before moving.

[Host: Kakashi Hatake]

[Chakra Pool: 508,776/509,950]

[Chakra Control: 90/100]

[Chakra Level: Kage]

[Chakra Affinity: All]

[Chakra Growth: +20,000 per day]

After touching the mark of 500,000 in chakra pool, his chakra was finally labeled as full-fledged Kage. The ever-growing internal energy made him feel refreshed every morning when he took a look at his stats.

Kakashi was happy, and with a smile on his face, which was hidden behind his face mask, he made a hand sign to create 40 Shadow Clones, sending half for Rasengan training and the remaining half to master the Four-Symbol Seal.

With this done, he went to the training ground, where Sakura, Sasuke, and Naruto were waiting for him. Today, he even had Sakura skip Medical Ninjutsu lessons, because Naruto and Sasuke, after their determination and the help of Shadow Clones, finally mastered Water Walking.

So, as decided, Kakashi would teach all of them Body Flicker Technique, and once that was done, he would teach B-rank Ninjutsu to Naruto and Sasuke.

Before the Land of Waves mission, Team 7 would be much stronger than their counterparts, and from Kakashi's calculation, before the Chunin exams, they would be even stronger. And that's what Kakashi wanted, to have them stronger much earlier, so he had less headache in the future, especially the whole lot about Akatsuki, Madara, Kaguya, and other Otsutsuki, though last one is still doubtful.

"Alright, are you ready to learn Body Flicker Technique?" Kakashi asked.

Sakura and Sasuke nodded, while Naruto said, "Well, that's good too, Sensei, but I'd like to learn that cool B-rank Ninjutsu you promised me."

Kakashi said back to Naruto, "You will get to learn that too, but for the next few days, you all will be practicing Body Flicker Technique and use it during your labor missions as well. Once I feel you are proficient enough in this, then will I teach you the B-rank Ninjutsu I promised as a reward."

Sasuke grunted. "Labor missions? Why would a ninja even need to do labor works?" he asked.

Kakashi replied simply, "Obviously for money..."

Naruto immediately stated, "But we get our cut of only around 1,000 to 2,500 ryo, and didn't you say that most of the mission money goes to the village."

Kakashi shrugged. "Then when did I talk about you?" he said. "It's obviously because the village needs to generate some extra income as well, and also have good public trust in them."

Kakashi waved his hand. "We are going out of track, let's get back to the topic," he said. "Sasuke, how much do you know about Body Flicker Technique?"

Naruto and Sakura were surprised why Kakashi asked about it to Sasuke and not all of them; after all, none of the three could use this Jutsu anyway.

They all looked at Sasuke who spoke, "Um, I only know that Shisui nii-san was known to be quite famous for this Jutsu."

Kakashi asked, "And..."

Sasuke shrugged; he didn't know anything else about Body Flicker Technique.

"..."

"You really know nothing else about it?"

Sasuke shook his head, and Kakashi sighed and thought, 'Well, I shouldn't be surprised, but still, the Uchiha Clan taught the C-rank Fireball Jutsu but not the D-rank Body Flicker to their Genin. It still sounds a little stupid, but... what can I even say!'

He shook these thoughts off and said, "Very well, so listen, Body Flicker Technique is a super-fast burst of speed movement technique, making the user ninja appear to vanish and reappear at some distance away, with the blink of an eye. Now open your eyes wide, I am going to demonstrate it to you."

With saying that, Kakashi instantly vanished and reappeared dozens of meters back from his previous position, and then with another burst, he moved ahead, back to his position.

The three of them were awestruck, and Naruto said, "Wow, it's really a cool Jutsu! Kakashi-sensei, are you sure it's only a D-rank Jutsu?"

Sasuke was also stunned, and asked, "Looks like Shisui nii-san was really good at this technique to be known for this!"

Kakashi nodded. "Yeah, he mastered it to the point that it looks like a teleportation technique..."

Sakura asked, "But Kakashi-sensei, isn't it already a teleportation? You just teleported from there to here, right?"

Kakashi explained, "It's usually mistaken by young Genin and new learners for a Teleportation technique, but it isn't. The only 'known' Teleportation technique that exists is only the Nidaime and Yondaime's Flying Thunder God, which are S-rank. Body Flicker Technique, as I told, is just a super-fast burst of speed movement and nothing else."

The Genin nodded, now very eager to learn it after Kakashi's demonstration. Kakashi then started teaching them how to use Body Flicker Technique.
