Jon wake up the next day after the battle royale. He try to remember what happen yesterday and sigh. In the end, he lost after fighting for more than an hour. But he's also happy because he finally can use Observation Haki, altough it's not that strong yet.
'Kid, this Observation Haki is like a sixth sense rather than sensor ability'-Kurama
Kurama suddenly speak to Jon, so he enter his mind scape.
"Yeah, instead of sensing people's chakra, we feel their presence, or intent to predict their movement using our spirit."-Jon
"Why don't you try to combine it with chakra sensing?"-Kurama
"It's a good idea, but i need to master the Haki first. I haven't train chakra sensing too, so it need to wait."-Jon
"If you use my chakra, you can always do those things easily you know."-Kurama smirk
"I don't want to be reliant on your power. The real power is my own power, right?"-Jon
"You're right, but i want some action too."-Kurama put his cheek on his palm while laying down like a lazy guy.
"Don't worry, after 2 years, i believe there are many strong opponent that i can't defeat alone."-Jon
"Hoo, how strong are they?"-Kurama getting a little excited
"I don't know for sure, i'm too weak to even measure their power. But my prediction is, they are as strong as Hashirama, or maybe stronger. Some people's physical power can be as strong as you or even Ten Tails."-Jon
"WHAT? Are you serious kid? We're talking about humans here right?"-Kurama
"That's just my rough prediction, not a real estimation. This world have many strange and mysterious power. You must know that every devil fruit have different power, and no one know how much devil fruits exist in this world."-Jon
"But, are you sure that there is someone with raw power on par with me?"-Kurama
"There is a devil fruit with your power that become my main mission. Mythical Zoan type, Inu-Inu no Mi, model: Nine Tailed Fox. I don't know it's real capability, but it can be something with your power potential, and there are other fruits too."-Jon
"Do-dog? They categorized me as a dog? MOTH*RF*CKER, BASTARDS."-Kurama
Kurama keep cursing the classification and naming for some minutes.
"Are you done?"-Jon
"Huff, huff, dammit, how dare they see me as a dog."-Kurama
"Well, maybe because fox bloodline and dog bloodline have the same source, and so is wolf. It's evolution theory you know."-Jon
"Tsk, they shouldn't use the dog name and use fox directly."-Kurama
"Well, enough about that, back to the topic. I have met someone with phoenix power too, you know. It's a legendary creature, i don't now if it's exist in your world or not, but, if there is a phoenix, then-"-Jon
"There is a dragon."-Kurama have serious look
"Yeah, altough i don't know yet about who have the dragon's power."-Jon
"Dragon & phoenix are legendary creatures, and if the devil fruits can grant these creatures real power, then the one that eat it can be as strong or even stronger than me."-Kurama
"Yeah, what they need is time to grow. The one with phoenix power is in his 40's, he can still grow stronger in this world. Altough not as fast as younger people, but it's possible."-Jon
"Well, if he's a phoenix, he will have longer lifespan, and keep getting stronger."-Kurama
"Maybe it's like that, but, there is someone that can defeat him even without devil fruit, and he's an old guy in his 70's."-Jon
"!! Really?"-Kurama
"Yeah, he repell the phoenix easily in one punch. System, show it to Kurama!"-Jon
The system then make a projection and show Garp repelling Marco in on strike. It also show all Marco's fight that Jon see in Marineford. Kurama have excited expression now after seeing this.
"That Marco, is as strong as a Kage, or even stronger. That Garp, i don't know his real power if i didn't meet him directly, but he can be as strong as Hashirama."-Kurama
"It can be, and he's old already, imagine how strong he was in his prime. If Garp can reach that power, other people can also reach it. That's what we will face after 2 years."-Jon
Kurama smile widely and got very excited. There's not many creatures with raw power on his level. He lost to shinobis because they can use ninjutsu, tricks and strategies. The only humans with close raw power with him are his father, Ashura and Hashirama.
"This world might not be so bad afterall."-Kurama smile
Jon also smile, he is very excited at their next journey in this world. He want to know about this world, so he need power. He also enjoy growing stronger and fight strong people.
"Ah, that's right Kurama, can you sense Dragon's power?"-Jon
"Only if he use his full power, but he only use a small part of his power against you. My guess is that he is as strong as Hashirama too, or maybe stronger."-Kurama
"Well, he's Garp's son, so it's understandable if he is as strong as Garp in his prime. Then Luffy will be like that too in some years, damn, i need to catch up."-Jon
"What are you so worried for? You have Madara & Hashirama's power, now you even have me. You can be as strong as my father one day."-Kurama
"It's only a possibility, and we don't know if there will be someone as strong as old man Hagoromo here."-Jon
After talking with Kurama, Jon continue his training with Dragon. Now he can use Observation Haki with his own will, not coincidentally. Dragon also say he use the most basic Armament yesterday.
"Huh? I don't know how it feel and i don't even remember it."-Jon
"Of course, you did it unconsciously. So starting today, you will train to master your Observation Haki and increasing it's range. After that, you will train your Armament, but first, physical training like usual. You can do your ninja training alone after we finished."-Dragon
"Aye sir."-Jon
Jon did his physical training, but Dragon tell him to train normally. He will need energy for Armament Haki training. So Jon didn't exhaust his energy in physical training. He is very excited with Armament training, so he'll do as Dragon's instruction.
After his physical training, Jon train his Observation. But now he will need to avoid the pebbles that are thrown by some people that surround him. He can avoid them at first, but then they raise their tempo and he start getting hit. He got hit once and lose focus, so he got hit again and again. They do it until lunch time.
After lunch, Dragon teach him Armament Haki. The concept is, he need to make his spirit coating his body parts. The key is his will, he need to have strong will to command his spirit to coat his skin and body parts.
"Huh? I don't really understand, can you explain it properly?"-Jon
"It's hard to explain, you will understand it later. Remember, command your spirit to coat your skin with your will!"-Dragon
Dragon then ask Jon to raise his hand in front of him. Then suddenly Dragon hit Jon's hand with a thin & long metal stick.
"OUCH, F*CK! OLD MAN, WHAT ARE YOU DOING?"-Jon rub his hand that got hit.
"I will keep doing this in our Armament training. That's why you need to command your spirit to protect your hand skin."-Dragon
"Wha- DON'T JOKE WITH ME!"-Jon
"Sabo!"-Dragon
Suddenly Sabo appeared behind Jon and hold him. Then some people tied Jon on a chair and his hands on a stone table. Then Dragon start to hit his hands with the thin & long metal stick.
"GYAAAHHH"-Jon
"Focus kid!"-Dragon
"Damn yo- GYAAAAHH"-Jon
Dragon keep hitting Jon's hand, and Jon have no choice but to try what Dragon say. He feel something flowing to his hands, but it's not haki, it's his chakra. He take it back and try it again, but he keep using his chakra instead of Haki.
"Can you try stop your chakra or deactivate it?"-Dragon
"I'll try."-Jon have tears at the corner of his eyes.
'System, can you block my chakra?'-Jon
[No host, but Kurama can]
'Kurama, please.'-Jon
'Hahahaha, alright kid, it's not so bad seeing your training.'-Kurama
'Damn you old fox, i will tie you with those chains again.'-Jon
'Hahaha, no problem, i can still see your suffering, hahaha.'-Kurama
'Tch'-Jon
Kurama then block Jon's chakra path so he can't control it for sometime. Now Jon's is like normal people but he have high amount of chakra. He can't control his chakra for now, so he continue his training.
Jon continue his suffering until his hands bleed. Dragon just ask doctor to bandage it, then he change to hit the feet. It continue until Jon got hit in all parts of his body. He can't even train his ninja arts at all because he's too hurt.
While he train his Haki, Robin train her devil fruit. She need to master it and find suitable techniques for many condition. She also need to train her stamina, because devil fruit use a lot of stamina.
Robin's devil fruit's power is basically cloning her body parts using flower petals. So she also need to train her physical power, because it also affect her clone's power. She train with Koala and other womens in the Army.
Jon ask Robin to train her physical power first, so she can use Rokushiki. He suggest Robin to train Shigan and Rankyaku as her priority. It will be scary if she can shoot shigan and rankyaku with her hand and feet clones. It will be a barrage of attack, and it will be very deadly.
Koala also try to ask Robin using Fishman Karate, but it seem Robin didn't have affinity with it. Fishman Karate is hard to train, even for Fishmans. So Koala is actually a genius to be able to succeed in training it.
For a month, their training routins are like that. They just increase their training intensity each time they make progress. Jon always do his training everyday even if he always get beaten up. His dedication also motivate the Revolutionaries, and now they also start to train.
Dragon is pleased by this, they have training schedule, but now they increase it. They finish their work faster so they can train longer too. So, not only they become stronger, they also become more efficient in their work.
In contrast to the enthusiastic Revolutionaries and Dragon, Jon feel frustated. He feel his progress is very slow, unlike his usual training. He try to think about it and finally realize it, he didn't train in ninja arts as often as usual.
Usually he will make clones and train many jutsus, but now he just focus on Haki. He need to block his chakra for some hours, everyday, so he wouldn't use his chakra instead of his Haki. By blocking his chakra, he can't make clones and control them, so he can't train a lot of things at once.
"Sigh, how can i increase my progress rate?"-Jon
'You need to learn medical ninjutsu.'-Kurama
'I already learn it, but it's not that easy.'-Jon
'Then you need to be more focus on it, stop your investigations about this world, you need to get strong first. You always got hurt after training, but your chakra is still full. So if you can heal yourself after training, you can train ninjutsu again. I don't have a problem with investigation, but Medical jutsu is your priority now.'-Kurama
'Hmm, you're right, it seem i need to focus more on Medical Ninjutsu. With Hashirama's gene i can make my healing faster, so i can heal myself fast and train again.'-Jon
Starting that day, Jon always train Medical ninjutsu using his clones when he train his physique. He stop when he train his Haki, even at Observation training. His clones also hinder his sense for now. He learn theory at night, and practical at day, that's his new training menu now.
