"I still can't believe you are still alive Ren." Duy as he looks up and down at Ren.
"And i already tell you that it's just a small trick" Ren started to get annoyed at Duy question him again and again for what felt like a hundred times already.
The two arrive at Konoha and are currently walking towards the Mission Department to claim their reward.
While the Jonin directly shunshin at Hokage Tower to report.
"Shouldn't we report that Uchiha Fumihiro attacked us?" Duy scratched his head as he asked Ren.
"No!"
"But why??" Duy really is confused about Ren's attitude.
Shouldn't they report to Hokage-sama to punish the Uchiha Clan? So why would Ren not want to report it?
"It's because we do not have evidence."
"What do you mean? He literally appeared in-"
"Appeared in front of us? So where's our evidence that Fumihiro did indeed appear and attack us?" Ren interrupt Duy and stops walking as he answers Duy
"That attack of mine turns him into ashes, and if we report it without evidence, the Uchiha Clan can turn the table and brand us as a traitor for killing one of their clansmen, and Hokage-sama can do nothing about it"
If Sarutobi didn't do anything to change Naruto,who house a Nine Tailed Beast which is an ultimate weapon for every big village, treatment in this village, why would he bother to help Ren, who is an outsider? Even if Ren is a genius, he wouldn't offend The Uchiha Clan just because of Ren.
"So, Duy as long as we don't talk about it, the Uchiha Clan wouldn't also talk about it. Though they may secretly attack us when we are out of the village so be careful." Ren said at Duy with serious expression, as serious as a kid can be.
"Fine, i get it..." Duy look down, not satisfied at all. But Ren's words make sense so he had no choice but to accept it.
They both then continue walking towards the Mission Department in silence. They separate after cutting the reward.
Ren then looked for Kushina and treated her to a meal while telling her his mission.
•••
"Ahh, why i cannot do it?" Ren clutch his head in frustration.
It's been a month since he started training Asakujaku [Morning Peacock, Duy's technique, but no matter how hard and how fast he punches, he can't seem to cause friction.
"Is it because i am massless that i produce no friction?" Ren sits down to think.
'If i just my use ability on my arms bones would that work? Since my flesh and skin have massed that should work right?' Ren thought since every time he activated his logia ability he would become massless and logia can literally turn any parts into Element such as the brain, bones etc. etc.
Ren stands up, then gathers light into his bones and strangely enough, his whole arm turns red like it was about to explode.
This happens because the light is passing through his red blood cells, which absorb most of the non-red colors in the white light emitted by his light. ... Light gets absorbed in his skin then it gets bounced around before getting re-emitted.
Swish!
Ren punches his red arm at high speed, because a thing that has mass can't travel at the speed of light.
A small spark can be seen with naked eyes but Ren is not satisfied and continue punching.
Swish! Swish! Swish! Swish!...
Pa!
A small flame, the size of a child fist, shot from his fist. But Ren is still satisfied.
"I did it... But..." Ren looked at his burned fist with frown.
He did it but at the cost of his skin and flesh burned and Ren didn't want that.
'I need to treat this before infection gets me...' Ren then stopped training and headed towards the hospital.
•••
After the treatment, Ren directly teleports to his house and cleans himself then sleeps, but the knock from his door prevents him from doing that.
Knock! Knock!
Ren sighs and walks to open his door.
"Ren let's play!" Before Ren even fully opened his door, Kushina came in and clutched his burned hand then dragged him outside forcefully.
"Aw..." Ren cried out in pain then quickly turned his burned hand into particles to get out of Kushina clutch.
"What?" Kushina stopped in confusion then look at Ren only to be shocked: "Wha -What happened to your hand??" Kushina's shock expression instantly turns into worry and runs beside Ren.
"Umm... I was training a new technique with my bloodline but... hehe."
"You are stupid!" Kushina rolled her eyes at Ren then poked his burned hand.
Ren eyebrows twitch in annoyance and pain at Kushina comment and her poking his hand.
"Stop it!"
"Okay" Kushina stops but when Ren looks around, she suddenly pokes his burned hand again.
"I said stop, it stings you know" Ren swat Kushina finger in annoyance.
"Haha" Kushina laughed cheekily at Ren then stuck her tongue and poke his burn again then started running before Ren swat her finger.
"You... I'm going to tickle you when i catch you!!"
•••
One week later.
Ren stopped training for a week and waited for his hand to heal, while waiting he played with Kushina and did some D-Rank mission to earn some money so he could buy himself food.
Now that a week has passed, his hand is good to go, he flashes in the mountains to train again.
'Although i manage to create fire from my fist through friction, it comes with a cost. If i have an Armament Haki though it won't be a problem...'
Currently, Ren is standing above the lake, like how Ninja uses chakra to stands on water, while thinking.
If a feather can float on water, which has an average weight of 0.0082 grams, so of course, a massless and human light, like him can do that too.
"What if i turn my flesh and skin in an elemental state while my bones stay solid?" A yellow light flashes in Ren eyes with that idea then positions himself.
This time, he would use his left hand as his right just got healed, so he had no plan to damage it anytime soon.
Ren fist up to his elbow glow, then he punch.
Swish!
Five consecutive punches but no spark.
Swish!
Ren punches again but this time ten consecutive and finally a small spark appeared at the last of his ten consecutive punches.
Swish!

An hour later.
"Why can I only create friction with this method?"
Because his flesh and skin become massless, due to his light ability, he can only create spark, as his bones is lighter than his flesh.
Friction is dependent upon the weight acting between two surfaces. When the mass is more, weight is more and so friction will be more.
Just like Duy, his arms are so heavy with muscle, thick skin and sturdy bones, which is the result of his countless training, combined with how fast he punches upon opening Hachimon Tonkō: Keimon [Eight Gates Released: Gate of Joy].
"Sigh, for now I'll temporarily stop training Asakujaku [Morning Peacock]"
"For now, I'm giving all my focus to this technique" Ren smirks and cocked his arm, his fist glow then he punch.
PEW!
A yellow beam the size of his fist, shoots out of his fist at the speed of light, piercing so many trees before it explodes at the boulder.
Light Fist
This, Light Fist, is inspired by Jiren's 'simple punch'. Ren then flash at the biggest boulder in his new training area and uses it as a target.
PEW! PEW! PEW!...
With Ren's every punch, a beam shoots out of it towards the boulder, destroying the surface of it.
He plans to train more if not for a messenger bird landing on his shoulder with letter tied on its feet. Ren took the letter to read.
'Head to my office. Urgent Mission. Hokage's order.'
"Urgent mission?" Ren stop training and flashes to his home and quickly clean himself before again flashing at Hokage's office door.
