Someone must pay!

"Hahahaha" Eragon couldn't stop laughing out loud even though he knew he must look like a madman.

Gleeful, he opened the system to buy the skill [Ki]

Learning Skills: {Mundane} {Combat} {Energy}

Learning Skills: {Energy} ==> [Ki - 10,000 exp]

Before purchasing the skill he found a safe place near the beach just in case it will be like the time he learned chakra, blacking out. He didn't want some wild animal to eat him like that, it will be so sad to die before having sex for the first time in this life...

Rubbing his hand as he felt the urge well up from within, excitedly pressing the icon of the skill, he waited.

1-second pass

2-seconds pass

5-seconds pass

15-seconds pass

'Mnn, nothing happens? what's wrong? Did I press it wrongly?' Eragon was surprised and uncertain, he looked at the system again to see what went wrong.

[Ding, warning! trying to combine two types of energy simultaneously puts a huge strain on the human body, with the host's current body there is a 95% chance of dying.

Do you wish to proceed? Y/N]

Dumbfounded, he read that notification several times while rubbing his eyes not understanding what he was seeing, or more accurately he doesn't want to believe it's what he was thinking.

"I-I-I'm AHHHHH" No matter how long he stared at the message, it didn't go away, finally accepting reality Eragon started roaring loudly in anger.

BANG

Kicking stones around him sending them flying, he grabs his sword as he cuts at trees randomly in an absolute fury.

Hufe~Hufe

"calm down, calm down" When he felt his sword was about to break he finally took a deep breath, doing his best to calm down, looking at the message again he did his best to stop his tears from falling down.

'If I knew this would happen I would have just bought ki from the start instead of chakra' he thought to himself sadly 'For starters, the reason I even bought chakras is that I thought It would be cool to talk with my Shadow Clone, and even that didn't happen! sob ~ sob' This time he really couldn't stop his tears from falling anymore, feeling like he was wronged by the lack of explanation in the system.

'Why is everyone getting AI with their system while mine needs experience points before it even starts functioning??' he complained while crying.

The more he was thinking of this the madder he got again, feeling like he was about to explode from the bubbling rage he picked his sword again about to slash trees when suddenly the pirate ship on the sea got in his line of sight.

"Someone must pay for this!" He narrowed his eyes, and killing intent burst out of them. walking towards the sea, he entered the water, swimming towards the pirate ship with such speed that even a fish-man will feel ashamed of himself.

"Moron! How many times have I told you not to sleep when we are supposed to watch the ship??" climbing the ship quietly like a ghost, he could see two men on deck, a sturdily-built middle-aged man sitting on a beach chair, sleeping, while a fat man looking angrily at him.

"yeah yeah just let me sleep already, one man is enough to look out for the ship" the middle-aged man sitting on the chair waved his hand with contempt and turned to the other side, quickly snoring again.

"*@##%, I really hope the captain would kick your ass when he comes back!" cursing in frustration, the fat man could only turn around to continue his watch duty, alone.

Smiling evilly Eragon sneaks behind the fat man with no sound at all, reaching his left hand to shut his mouth from screaming while his right hand holding the knife giving the fat man a big smile from ear to ear. His movements were precise like he practiced this numerous times already.

Exerting strength in his hands he gently put the man's body down without making a sound.

Turning around, the man sleeping on the chair didn't wake up, his snoring still rings on the ship's deck. Suddenly having a brilliant idea he aims his knife and throws it as hard as he can, with a streak of obsidian light, the knife sink into the man crotch area with a sickening sound.

"AHHHHHHHHHHH"

Feeling pain the like he never felt before the middle-aged man squall loudly in a coarse voice, veins started to stick out on his neck and temples from all the pain and screaming.

'I bet it hurts like a bitch ' looking at all the blood as the man rolled on the ground Eragon felt a shiver run through his pants, finally, after a few minutes of screaming he passed out.

Thoroughly satisfied, Eragon felt his pent-up emotions finally vented, calming down.

Thump, Thump

Grabbing the two bodies, he threw them to the sea, he never saw any sharks around here but he bet with all the blood some fish will eat the bodies. Eragon decided on going around the ship for a tour, finding all sorts of weapons and tools. when he reached the warehouse he found some gold, counting roughly there should be about 500,000 berries

Feeling happy with the free money, he eventually starts to consider what he should do next.

'mmm, it won't be wise to take a risk for 5% chance and buy ki, since it said "currently" in the message, it must mean that's in the future the percentage of danger will get lower' while he was contemplating, he opened the system to see what to do with his experience points since he can't buy the skill he wanted.

Learning Skills: {living } {battle} {Energy}

The first thing he did was buy the skill [Sword Mastery], he couldn't get a sword the past month and the skill won't be awoken before he does some sort of action related to the skill. Remembering how Mihawk used a sword to split a huge iceberg during the War of the Best in Marineford, he got really impatient to raise the skill level.

[Ding, new skill learned]

Feeling his control of this sword getting a lot better than previously. He tries swinging the sword around to see if he can do some air blade with it, although unsuccessful he feels like he was definitely in the right direction.

+5% speed increase when doing hand seals]

"Oh, finally I got myself a sub-skill" Eragon's mouth curled upwards, finally feeling relieved. Information started to enter his mind teaching him about hand signs making him understand that he only got E-rank techniques. Slightly hesitating he put 5,000 experience points into the sub-skill, getting himself more skilled in doing hand signs and more advanced techniques at c-rank.

[Ninjutsu - level 5 (50/6,000)

Allows the host to instantly learn Ninjutsus techniques per the skill level.

+25% speed increase when doing hand seals]

"Hahaha, now I finally get to use ninjutsu!!" Getting excited Eragon immediately started doing hand signs skillfully as if he practiced for years.

"bunshin no jutsu!" someone who looks exactly like him appeared in front of him, excited he tries to touch his clone only to see his hand passing right through it.

It was only a weak clone with no substance, if he wanted to create one which can aid him in attacks he has to learn more advanced bunshin no jutsu techniques.

Deciding to use an element attack next, he started to consider which one to use only to realize he didn't know his chakra attribute.

"Damn, let's just try to use each one and see what happens" not having a chakra attribute testing paper, he couldn't find a solution, eventually he decides the best way to know his chakra attribute is to test a Jutsu from each element.

[Fire Style: Flame Bullet]

He finished forming the hand seals, slightly bent backward, brought his fingers near his mouth, and blew out a fireball towards the sea, watching as a large amount of steam started to rise upon impact.

[Water Style: Gunshot]

Not stopping he immediately moved on to the next jutsu, firing out a water bullet from his mouth with incredible speed. He couldn't see any effects as the water bullet just entered the sea but he was certain that if it was to hit a person it will definitely do some damage.

[Wind Style: Gale Palm]

Clasping his hands together, wind compressed and transformed into a powerful gale shooting in all directions strongly.

[Lightning Style: Oppression Horizontal Chop]

Raising his hand high he swings it forcefully to his side directly into the cabin next to him, his hand penetrating deep inside without any resistance.

He didn't really have a suitable Earth Style Jutsu to use on a boat in the middle of the sea but it didn't matter, his earlier testing already confirmed everything. Being able to use those elemental Jutsus just like that meant he indeed didn't have to practice the hand signs beforehand, it was already included inside the skill [Ninjutsu]

He looked at his raised hands, dazed.

"Hahahaha, I'M A GENIUS!!" Snapping out of his shock he started laughing up roaringly while clasping his hands strongly, completely forgetting this strength came at the cost of not learning his precious Ki….
