Training part1

After eating the devil fruit, Sin asked if Ash felt different, and Ash responded by saying that he felt significantly stronger and faster.

Sin still couldn't figure out what type of devil fruit he ate.

"What happened after i lost consciousness?" asked Sin after hesitating for a while.

"Lord Augustus's Vivre card, is no more," said Ash sadly.

Sin was expecting this, but hearing still made him sad and angry.

*Huuuuf...fuuuuu* taking a deep breath, Sin calmed himself.

"Ash, I want you to train me, I don't care even if you beat me half to death, I want to reach your level as fast as possible," said Sin.

"I can't..." Ash stopped when he noticed his young master's glare.

"When?" Asked Ash.

"Right now!" said Sin before leaving.

*Sigh* Ash looked at Sin helplessly, but when he disappeared, Ash expression turned solemn.

'For the polite, naive and timid young master to mature overnight...' Ash though.

Killer intent flashed in Ash's eyes as he thought about the fools that will come for his young master's head.

"2...23...24...2...25...*Thud*" Sin collapsed.

*Huff...Huff*

"This-this is pathetic...*pant*," said Sin.

'Even Luffy who is 3 years younger can probably do a couple of hundred push-ups' though Sin.

He spent all day testing his limit.

Even Ash was speechless because of the result.

3 years before the plot!' though Sin as his eyes turned bloodshot.

"1. 2. 3. 4. 5. 6... 134...135...136... *thud*" Sin suddenly felt a sharp before collapsing.

"Y-young master!" Ash exclaimed.

"I-i need water," said Sin weakly he couldn't move a muscle.

_Later

Sin looked at his arm and concentrated, and a few seconds later a very thin pale blue layer coated his right arm.

"My arm doesn't feel sore anymore, but that can't be said for my chest and the left arm," said Sin.

"What do you feel?" asked Ash.

"I feel as if I could crush a rock with my right arm, and I also feel the power...some kind of energy running through my veins. So your saying I had this layer of energy all over my body?" asked Sin.

"Yeah," said Ash.

"I'm starving..." Sin said while rubbing his stomach.

"That's normal, devil fruit users require more energy, " Ash explained.

__Later

a few hours later Ash and Sin were sitting in front of a campfire, in front of them was large chunks of cooked meat, roasted fish and fresh fruits.

Ash and Sin were in an inhabited island located in south blue, food, they found shelter and the food on this island was enough to sustain a city for a decade.

*Munch...Munch* Sin was surprised by his newfound large appetite.

__2 months_Later_

Sin was doing his last series of exercises for the day.

"...498...499...500," said Sin.

In the past 2 months, Sin and Ash trained separately.

Sin was getting better and better at manipulating chakra, he called the pale blue energy, chakra because it reminded him of the anime Nar*to.

If he wanted, he could make the pale blue energy stick to stuff, like the tree walking technique, he could also change the texture of the energy layer to mimic faces or clothes, similar of Nar*to's Henge technique.

Plus the physical boost, it shows just how incredible the potential of this devil fruit, he later called it the Chakra Chakra fruit.
