In the next morning...

Shisui went to the 3rd training ground early in the morning to wait for his sensei and not too long he saw Haru and Kakashi walking towards him.

"Goodmorning Haru-sensei, Kakashi-sensei" greeted Shisui

"Goodmorning Shisui-kun" replied Haru

Kakashi just nodded

"Okay since this is the start of your training with me, I'll give you this as a gift for my first disciple" said Haru while taking out a ring and gave it to Shisui

"Sensei is this a storage ring?" ask Shisui

"Yup but that ring is special since my mark is in there, I can teleport to you whenever you are. And also it serves as an emergency call when you are in a pinch you just need to insert some of your chakra to the gem on that ring I will know as it serves as a signal that you are in trouble and quickly teleport to you, I would not want my student to be in danger am I, but only use that if you really can't handle your opponent, I trust you that you have good judgement on your situation, am I right?" said Haru

"Hai! Sensei Thank you" said Shisui

"Okay enough about that, you may start your training give me 100 sit-ups, push ups, squats and 10km run now"

Shisui then started to do Haru's order and did his training. Haru and Kakashi also did their own thing.

After about 4hrs Shisui's physical training was done, he laid on the ground panting heavily. Haru came to him and said

"Good now rest for a bit and we will resume with your kenjutsu training. Have you done any kenjutsu practice before?" 

"Yes sensei I had done the leafs sword style up to chunin level" said Shisui

"Hmm the leafs sword style is also good, it helps in your foundation training. Okay you do the leafs sword style for now and I will teach you the swordsmanship practice that I learned, although it is quite different from Hatake clan swordsmanship but it is still good. And after you finish your foundation training I'll teach you how to do this"

Haru then took out a branch, wave the branch in his hands and it pass through behind Shisui. When Shisui turned around he saw a deep cut on the ground and this shock him. He turned to Haru 

"S-sensei How?" ask Shisui

"Hehe in swordsmanship this is called the rhythm of everything followed by Tobu zangeki in which it had 15th compression as maximum, what I did just now is the 1st compression. 

When you are a master swordsman, you can use anything as a sword whether its your finger, hands or just an ordinary twig. I will teach it to you when the time comes."

"After your training with the sword would be to practice shunpo first, shunpo is a movement technique that can be use in swordsmanship or any other fighting style, you already experience it during your fight with Kakashi yesterday when he suddenly appeared behind you. This also serve as a foundation to your shunko training."

"After that is your observation haki practice then ninjutsu practice, so we had a long day ahead of us, you start your kenjutsu practice, I'll ask uncle Sakumo if I can teach you our sword technique."

"Hai!"

Then Shisui started his training.

After 6 months...

In the 3rd training ground

"Haru, Hokage-sama wants me to go back to the sand borders to help father, since Jiraiya-sensei was sent to the mist to help them there, they are starting to make their move there." Said Kakashi in a sad voice

"Oh Hmm when do you leave?" ask Haru

"Tomorrow, early morning"

"Hmm okay since I was planning to have a close-door training since I felt like I can breakthrough my bottleneck. Can you bring Shisui along with you and help him train?" Said Haru

"Fine! But you must spend the day with me" said Kakashi

Haru giggled and said "Okay, oh and say thank you to uncle for approving me to teach Shisui our clan technique and oh yeah, you can also teach uncle the rhythm of everything and tobu zangeki, you can also teach him shunpo, observation haki and armament haki if you don't have much to do. I'll go back to the battlefield if I finish my close-door training" 

"Okay"

"Shisui, rest up for today, tomorrow you will go with Kakashi in the borders and you train with him there, I will go to a close-door training so no one will teach you except him, he will also teach you the shunko (Thunder) after you mastered the wind type and he will also continue your training with armament haki" said Haru

Shisui's progress in the past months are bountiful, at his age he already had a strength comparable to a jonin; His chakra reserve was at jonin level, his swordsmanship is also great he already achieve the rythm of all things and is at the 2nd compression of Tobu zangeki, coupled with the Hatake clans technique made his swords style frightening, He already mastered the 3 variations of shunpo and is at the beginning stages of shunko (Wind). Haru also taught him how to master the nature and shape transformations of all his elements and he mastered them in 2 months, well they did not use any kagebunshins since his chakra reserves is not that high.

So he mastered them one by one, this shows just how much is a genius he is. He also learned many ninjutsu techniques from Haru. He is also at the basic stage of observation Haki, during his training of observation haki shisui's 1 tomoe sharingan evolve to 3 tomoes which surprises Shisui since evolving his sharingan was very difficult but he did it in those 6 months, well who wouldn't when you are force to be blindfolded and just using his perception to dodge throwing projectiles towards him, and sparring with people who are stronger and faster than him everyday. He also just finish his foundation training of his body a week ago and is started to learn armament haki today.

"Hai sensei thank you" said Shisui

Shisui then started to turn around and go home, while Haru and Kakashi spend the day together.

Next morning...

At Konoha's entrance

"You two need to be careful alright" said Haru

"Yeah"

"Hai sensei"

"Goodbye!" said Haru

"Bye"

"Bye sensei"

Then Kakashi and Shisui turn around and left Konoha.

"Now let's do this!"
