10 Rock Smashing Fist

Author's Note: As one of our viewers "whycantistop" has suggested that Sharingan would be too OP, I have decided to postpone it and instead introduce Energy bending. But it can only be achieved after the MC masters all 4 basic bending.

-----------------------------------------------

David decided to not overload Hiroshi and his sons with so much information. Akira and Renji's minds were already fried so they decided to give up on understanding.

"All I can say is thank you but don't forget that I m still your martial arts master" Hiroshi said while he had a glint in his eyes.

'I can't be soft on my own disciple no matter who he is. A moment of weakness like this doesn't look good on a man like me'

"Yes of course. Now that I have passed your test, what time should I come tomorrow ?" David asked while getting up.

'If I play my cards right I can make him and his family do things on my behalf. I don't have any ill intentions towards them. They may not be as rich as the Yaoyorozu family but they are way more influential' David thought

"Wait according to tradition every personal disciple gets to choose a martial arts technique they desire no matter how strong it is. So come with me " Hiroshi said while walking out of the door.

David followed his master while Akira and Renji were still in the room. For a few seconds, they stared at each other as if asking "was it all real?" then they both sighed at the same time.

"How can a mere 4 year old have such a perspective? I have heard dad talk to uncle but I thought he was exaggerating. Now I believe what dad said was true. Our brains are really rotten because of these peaceful times" Renji said

"Hahaha... it's alright and I kinda like that kid you know. He has even inspired me to work hard now. Renji from tomorrow even we will practice or after a couple of years David will defeat us and then go to school" Akira said while putting an arm around his brother's shoulder comforting him to which Renji nodded and said "Let's see which technique that little monster will choose" and they both went in the same direction as David and Hiroshi.

In an underground library, David was going to different martial arts manuals but he couldn't find anything that could catch his eye but then a manual caught his eye. Mainly it was the name of the manual which made David flinch as he has heard it before but from a different anime.

'Almost all of the techniques here are related to fist or finger strength. Just like the practice martial arts CD which the old man gave me a month ago. He seems to be up to something. Lets go with the flow for now'

David picks up the manual and starts going through the first few pages when he heard a voice from behind him.

"Water Stream Rock Smashing Fist. A perfect combination of offense and defense but is brutal for today's world. If you are able to achieve fluid movements of your body, you can incapacitate or even seriously injure anyone at close range." Hiroshi said while looking at David

"Master, do you practice this technique?"

"No my body and quirk is made for stiff movements. I cannot perform such fluid movements as shown in the manual" Hiroshi said while moving his head sideways.

At that time Akira and Renji came to the library as well. When they saw the manual in David's hand they didn't react as they were not aware of the potency of this technique.

"Master I will take this manual then"

"As you wish. Renji have some1 deliver a couple of large rocks to my training ground. " Hiroshi said while looking at Renji who nodded.

"Now this manual is a gift as per the disciple ceremony of our ancestors, but I want to gift you something personal as well. So tell me do have any weapon that you want or do you wish to fight hand-to-hand combat?"

"I think I will stick to fist techniques for now." David said looking at Hiroshi because he knew his master had something in mind for him.

"I do have a technique that will let you use your hands as a sword. This technique is called swordless" Hiroshi said with a big smile on his face.

The expressions on the Face of Akira and Renji changed as they knew that swordless was their father's strongest technique and no one in the family had a body suitable for it. And then they heard David say something had shocked them even more.

"You checked my body when you first met me and realized that my body is stronger than normal folks. So you gave me those CDs to practice. Let me guess the CDs contained the basic practice regiment to master swordless and the technque which i chose just now states that when mastered a blue aura surrounds the user's hands. And you plan to use that blue aura to help me master swordless as I make turn my body into hard metal which is your quirk" David said with a sly smile on his face.

'Dammit he saw right throw it again.' Hiroshi thought with a frozen smile as he then hung down his head as if a kid has been caught by his mother lying.

Akira and Renji found this scene very amusing. Not everyday they see their father in such a sorry state and they bot couldn't help but laugh which made Hiroshi feel more embarrassed.

"Yess your right...ugh. I didn't know I would have such a bad day" Hiroshi said with an annoyed expression.

"Okay I will learn swordless if you think my body is suitable for it. You are the martial arts master so i don't doubt you at all regarding this"

The smile on Hiroshi's face returned instantly after hearing this.

"Great great from tomorrow every afternoon I will teach you martial arts and when you master the aura I will turn your hands into the sharpest swords the world has ever seen" Hiroshi was as excited as a kid on christmas.

Thats when they heard Hina voice saying that John is waiting. So they all returned to the main hall.

"Mr John I will send a car every afternoon to pick up little David if that is okay with you" Renji said.

"Please dont take such trouble sir. I'll have his brother drop him off everyday" John said.

"Its no trouble Mr.Carter, David is our father's disciple. This is the least we can do. We will also send some training materials by tonight at your residence so that he can practice at home" Akira said.

"Thank you sir. I'll see you tomorrow master" David said.

"Yes take care" Hiroshi said.

After John and David left Hiroshi sighed and Akira and Renji couldn't help but laugh which confused Hina.

"What happened dad and uncle why are you laughing at grandpa?" Hina asked with a confused expression.

"Nothing the master got a suitable disciple" Renji said while looking at his father.
