[Your next teacher will be... Rob Lucci!]

As soon as she said that information flooded my head about him.

Rob Lucci was an elite government assassin. He was the strongest member of CP9 in history. After his defeat by Monkey D. Luffy at Enies Lobby, Lucci was dismissed from CP9 by Spandam, who declared him and the other assassins responsible for the Straw Hats' havoc on Enies Lobby. However, within the next two years, he managed to be reinstated into Cipher Pol as part of CP0, this time as Spandam's superior.

Wow, this guy is good. While yes I already had assassin training from Izuru, Lucci offered more refinement and a unique skill set such as his Rokushiki techniques.

Soon the world around me began to change and my bedroom glitched out of existence and it began to change to that of a classic dojo. Rob Lucci also appeared here and he soon opened his eyes and looked at me with an emotionless gaze.

Based on his personality I knew that this guy would be harsh on my training.

I looked at him with a determined gaze as I said, "I want to learn from you."

Lucci still looked at me with a cold gaze, but I knew that despite the personality he will still train me because Guru summoned him.

Without saying anything Lucci used Soru to move at superhuman speeds and punched me in the stomach, while I did see him move I couldn't react in time to block his attack and getting hit by him was incredibly painful.

I immediately began to stand up as despite the pain I'm used to it and with the Hercules Method it wasn't as damaging. I looked at him and there was a savage grin as he transformed into his leopard form. 

Based on his personality, I knew that this was going to be tough for me.

...

Training with Lucci is pretty much like Koby and Helmeppo training with Garp, all he did was beat me up till I get stronger. 

Though because of my already decent superhuman body I was able to last much longer and even land some good hits on him, but I knew that it will take a lot more than that to defeat him. One Piece characters literally weaponized their willpower, so they're going to be very difficult to defeat.

Luckily, it wasn't all me getting constantly beaten up by him, he taught me various spy skills he learned from his time as part of CP9 and CP0.

He taught me his carpentry skills and knowledge about ships, his sawyer, treenail, and bolt specialist skills. He made me practice until he deemed me an expert. Given his personality he expects nothing but the best.

Soon though he began to teach me his spy skills he learned during his time with the World Government. He taught me his infiltration, disguise, intelligence gathering, and a bunch of more skills that related to a spy.

Though, my favorite training was definitely the Rokushiki.

"You need to have control over every fiber of your body." Rob Lucci advised as he looked down at me sitting.

Training Rokushiki was in truth not that hard for me considering my already strong physical capabilities from my training and the Hercules Method. 

'Tekkai' my body hardens to become as tough as iron. Tekkai can also be used to enhance the user's attacks by said increased hardness. Though how strong it is depends on the person's physical ability. However, that goes both ways, as the users strength is the limit for how much force they can withstand, and powerful blows over their limit will break through.

When activating it I'm unable to move and to use it properly I have to do an action and then activate it. So, I need to throw a punch and right before I hit the person I activate Tekkai to maximize the damage. 

Geppo is basically kicking the air using incredibly strong kicks and to fly I basically need to kick the air multiple times in succession. 

Rankyaku is is a powerful projectile technique, in which the user starts by kicking at very high speeds and strength, which results in a sharp compressed blade of wind. It can deal great damage to the human body or slice through objects. Though it always depends on the strength of the user. 

Soru is a movement technique that allows users to move at extremely high speeds in order to avoid attacks, as well as to attack at higher speeds and with greater power. It was revealed that the principle of this move was to kick off the ground at least ten times in the blink of an eye. 

Shigan allows one to use their finger as a weapon. It's a close-quarter combat technique, in which the user uses their finger to pierce the target's flesh, at a very high speed. The resulting wound is roughly the size of a bullet wound. Combined with their speed and strength it's very dangerous.

Kami-E is a dodging technique that users to relax their body and make it take on the characteristics of a piece of paper; this grants the user extraordinary flexibility that allows them to avoid any attacks. The body being in this paper-like state also allows the user to float on the wind, as well as the ability to bend and contort their body.

I have to say practicing and learning these techniques were interesting, while in theory I could understand how they work as it all depends on the users strength and speed it was still difficult to learn.

Practicing Rokushiki was very difficult as while my body was strong it was not at the level where I could fully bring out the full potential of the techniques.

So, I had no choice, but to practice the Hercules Method. Rob Lucci put off my Rokushiki training and had me practice more of his various skills and strengthening my body.

I repeatedly got beaten up by him and because I didn't want to back down I practiced my Hercules Method. I only started for a bit and didn't progress too far as it only gave me basic abilities.

As I didn't want to keep getting beaten up I had to practice. As time passed I progressed with the Hercules Method, I could feel the changes in my body I was getting stronger, my mind is sharper and I could pick out details and process information much faster, my regeneration was stronger as when Lucci hit me with a shigan I was able to heal quickly and because of my strength it didn't give me anything fatal, I had a form of x-ray vision able to see the biology of living creatures, as well as precognition able to see seconds into the future.

Surprisingly, my body didn't become a tall, large and muscular build. The most likely reason is because of the fact that my mind subconsciously didn't want to have a large muscular build. Truly the mind commands, the flesh obeys.

Despite my body not being tall and muscular my body did still somewhat grow, though not to a noticeable degree. I was a bit taller and muscles were compact like that of a swimmer build.

I don't like to admit, but I spent most of my time practicing the Hercules Method and I because I dedicated so many weeks practicing it non-stop, I feel like I fully mastered it already, but I knew that while I was at a very high level I haven't fully mastered the method as I still feel the need to eat and drink, but not as much.

After deciding I had a strong enough superhuman body I returned to practicing Rokushiki with Lucci. He instructed me the basics of each technique and with my superhuman body stronger I started practicing the Rokushiki techniques. 

With my enhanced body I easily able to use Soru, Geppo, Shigan, and Tekkai. Shigan was easily mastered by me as it was pretty much using my strength and speed and piercing people's bodies with my fingers or my entire hand.

Soru was a bit difficult at first as kicking the ground 10 times in the blink of an eye was hard. Though with time, persistence, and constant spars with Lucci forced me to quickly master it.

Geppo though was surprisingly easy, but then again I was just jumping high and doing a "double-jump". It was easy with my enhanced body and I just jumped again, a bit of practice and I was able to do it quite easily.

Tekkai was another easy one as it pretty much hardens my body to the level of iron. With my enhanced body it was quite easy to do as I pretty much commanded my body to harden. It was like flexing a muscle.

After mastering those 4 techniques which were the easiest for me I quickly moved on to the harder techniques which was Rankyaku and Kami-E.

Honestly despite Rankyaku being a projectile technique it was quite hard for me to do simply because of the fact that while yes, I can kick hard and send a shockwave I can't really compress it and shoot it out like a blade. This must be One Piece physics at play.

Eventually I did manage to do a proper Rankyaku, I suspect that Guru had something to do with it, but honestly I can understand it, as this martial art is literally not possible for regular people in a normal world.

Kami-E was an interesting technique as it was all about relaxing the body and taking the characteristics of paper to dodge attacks. Despite this technique sounding hard it was quite simple as it was just relaxing your body and dodging which I had no problem doing mostly thanks to Guru.

I spent a lot of time honing the six techniques of Rokushiki to the level of absolute mastery because it was needed to do the final technique Rokuogan.

I must have spent months constantly practicing Rokushiki because even Lucci was impressed that I mastered it in the span of months. Soon I knew that it was time for my final lesson.

...

Rob Lucci standing across from me with his arms crossed said, "You have now mastered the other six skills that is required to learn the seventh technique, Rokuogan."

Lucci then demonstrated the technique for me as he places both his fists right in front of me and focusing his physical strength he launched a devastating shock wave from his knuckles in a forward direction, causing severe internal injuries to me.

Getting hit with that was abosolutely painful, I felt my bones break, organs ruptured, and more severe internal injuries. Though despite that I commanded my body to stop which it did.

Using that demonstration I eventually decided to practice it myself. I focused all of my strength and I too launched a devastating shockwaves from my knuckles and I did the same thing Lucci did to me.

Lucci got up with a savage smile as he said, "You have mastered all of my skills and the things I taught you now go, enforce Dark Justice!"

After declaring that the world started glitching around me and so has Lucci and soon it returned to my room.

[Alright! Your assassin training is finished, what else do you want to learn and refine?]

'I'm not sure actually. Though I do have questions about your abilities?'

[Uhm, ok what do you want to know?]

'What can you really do?'

Guru remained silent for a while most likely contemplating how to answer my question, then she spoke.

[As the Noble Shard of Abaddon in charge of studying and learning all martial arts techniques and other ways of fighting for future cycles, that's not my only job.]

'What's your other jobs then?'

[My whole designation is about knowledge and pretty much how to weaponize it. I summon various mentors from my vast vast archive and I make my host learn all their skills and see what they can do with it whether it be unique combat skills, science, and more.]

'Ok, so what would happen though if you are gone? Would I lose access to everything I learned?'

If that was the case then that would absolutely suck. Luckily, Guru answered my question.

[Oh no absolutely not, learned skills such as your combat, science, and various other skills you trained for are permanent as you learned them and aren't power granted, sure I temporarily boosted your intellect, but you still learned them. Though for power granted skills that's very different.]

'What do you mean by power granted skills.'

[Well, it's quite simple my mentors aren't just regular people, but they included magicians, psychics, and anything considered supernatural. You can learn their abilities, but they are through me that you gain access to them and if you do lose access to me then all those supernatural abilities are gone too unless you can replicate them.]

'What about my training how does it work?'

[Like I told you, you are transported to another dimension dedicated to your training and time passes differently in it.]

'Alright, but what about my mentors?'

[What about them?]

'Are they exactly who they are?'

[Yes and no. They are perfect exact copies of the original so good that neither can tell which is fake. Think of the Mauler Twins from Invincible.]

'Is there anything else that I should know about?'

[Not really, now what mentors do you want to learn from to refine your skills.]

Now that's the hard part what do I want to learn. I already have a strong foundation to start, but I guess it helps to learn more.

'I want to refine my hacking skills.'

[Alright! Now let's find you a hacker teacher.]

Guru remained quite for some time and then she spoke once more.

[Aha! I found you the best hacker you can learn from!]

'Oh who is it?'

[Your next teacher will be...]

Author's Note: The sixth chapter of his training arc is finished! I will post a chapter explaining his profile after this training arc. Four more chapters to go to be done with the training arc. The teachers that are remaining are mental techniques to help him develop his own backup personality, disguises, foreign technology, and finally Batman himself. I might also just do a montage of extra various mentors.
