Super Duper Lucky System

 "Tell my father i be back after i'm strong enough to defeat him within 5 seconds" Sill whisper to the butler ear and continued his walk down the mountain.

Walking down from mountain Sill kept thinking that he forget something important but couldn't recall what. He too focus on Heavens Arena that he forgot the reason for him to get strong in the first place. 

At Heavens Arena Door..

Sill smile at the receptionist girl but the the girl only have a straight face and says "viewer or fighter?" while showing Sill paper with the viewer price and fighter. 

Sill smile akwardly cause of the receptionist girl didn't greeted him and didn't show any smile even a little.

"Fighter" Sill said and give the receptionist some money enough for the fee of Fighter. Sill had to fill some paper to join in as a fighter. After Sill give the paper back to the receptionist, she take a quick look at Sill paper and frowned a bit as she look at Sill. While pointing at age part on the paper she said, "you got it wrong at this".

Sill chuckled a bit after what he saw. Sill just casually write on that paper that he forget what he write on age part. "Hehe i forget that with this body of mine nobody would accept I'm 6 years old" he muttering in his mind and just add another '1' before 6. Just like that Sill become 16 years old to receptionist eyes.

After finished proceeding those paper Sill was told to wait for his first fight in the waiting room. 5 minutes he walk and arrive at the waiting room. There is a lot of people, Sill thought that he would meet some 'cliché man' but nope. Everyone was on their own work. Some were doing weightlifting, some were meditating etc. etc.. Nobody would offend people with Sill muscular build body.

One by one person out of that waiting room. Sill got bored while waiting and he just buy a Phone from system. Of course the Observer give him restriction in using phone from earth and those restriction were that he can only play games, even though system made it connected to earth, he cannot do anything other than play games.

One games after one games Sill played while waiting for his turn. After two to three hours of waiting Sill got called by referee into the stage.

Sill is on the stage staring at his opponent. His opponent was a man with thin muscular build almost same with.. nah.. he will KO in one hit anyway. Sill want to finish it already but he wondering why the referee still not start the match and let his opponent pouting some bullsh*t like ' I'll beat you in a minute' or 'you better surrender before i beat you up' and same kind of bullsh*t.

Sill just wait patiently until his opponent shut up. Referee immediately start the match after Sill opponent shut up. About 1 seconds after the match started, Sill already KO his opponent, and it takes about 1 minute for referee processing to what happens Infront of him then declaring Sill as the winner. Sill didn't even use his haki in that fight.

One week has passed, and now Sill is in his room waiting for his first fight in 200th floor. Yes, it takes him one week to arrive at 200th floor. Normally with Sill strength, 2 to 3 days was enough to get in 200th floor but Sill was too focused on his new developed nen ability. Sill buy Training Room in System and train his new nen ability there. Training Room have the same time ratio with outside but it's also have gravity control and also Sill can add some practice bot within. To use Training Room Sill need to be in a 'room' and no matter what kind of room. while people on the outside cannot hear a thing within his room, he still can hear if someone knock the room door.

The floors above the 200th offer no prize money, only fame and glory. All weapons are allowed on this floor. A fighter has 90 days to prepare for any fight, though it's possible to fight everyday if wanted. The 21 highest ranked competitors are called Floor Masters because they're given their own floor between the 230th and 250thfloors. Losing four matches results in disqualification, while winning ten matches results in being awarded the right to challenge a Floor Master. The 251st floor of Heavens Arena holds a biennial tournament called the Battle Olympia, and the victor is allowed to live on the 251st floor in an exclusive penthouse.(A/N: copy paste from hunterpedia...again XD)

After got called by the referee, Sill now on the stage facing Mr.Stone or that what people call him. Mr.Stone was an old man, maybe 50 to 60 years old, but with his big build body like Escanor(seven deadly sin) no one would underestimate him. Sill do some research about Mr.Stone before getting on stage. People call him Mr.Stone cause when he fight he would let his opponent to attack him while him never budge an inch and deliver finishing blow on his opponent. His defense is tough as steel but maybe cause Mr.Steel sound a bit weird, people start calling him Mr.Stone.

"Start!" The referee shout.

Sill smirk a bit when seeing Mr.Stone just standing without moving an inch. Sill began coated his hand with armament haki making Mr.Stone stupified a moment then started to get in his defense stance. Mr.Stone started using Ten to coat his body making his body hard as steel. Sill run straight to Mr.Stone and giving Mr.Stone punch straight to his face. Even Mr.Stone doesn't have observation haki he still is a experience fighter who fight a lot in his life. Stone was gifted some kind of instinct after lot of fight. 

Following his instinct Stone blocked Sill hand maybe at 8 inch from his face. Then Sill continued with punching and kicking right left, right left.  Stone depressed and couldn't accept that he is being cornered by a kid who doesn't seem to have half of his age.

Stone enraged and countered Sill attack with punching straight to Sill c.h.e.s.t. Stone know that with Sill speed, Sill can evade his punch with ease but suprisingly his punch actually hit Sill c.h.e.s.t and threw Sill a few meters away but still in standing position. Stone grinned all over his face with thought, "haha, this kid doesn't seem to be good at defending".

While Stone grinning with his thoughts, Sill also grinning all over his face. Since Sill requested a death match, both of them cannot surrender. It's either fight or die!

"Crows Bomb!" shouted Sill. A moment later two crows can be seen on Stone right and left shoulders. Stone panicked after realising there is two crows came out of nowhere landed on his shoulders. The crows disappear after Stone shrugged it away but it's appeared back after a moment. Actually after the two crows landed on Stone shoulders, Stone feel his power has been raised up a couple times.

Stone just ignored the crows after trying to make it gone a couple times. He don't know what the crows abilities is, but now he feel like he is the most powerful after his power has been raised up a couple times and for now he just want to KO Sill. Stone dashed towards Sill with his new speed and send a punch to Sill c.h.e.s.t again, even though Stone speed has been raised up, with Sill observation haki, Sill dodged with ease.

The first hit that Sill received was due to one his new ability conditions. Almost all Hatsu or nen ability need to have a condition, and the more harder condition to fulfill the more stronger the ability. Sill new created ability called Crows Bomb.

Crows Bomb- ignored any non-physical defense and explode. Target need to do a willing skin contact with host such a touch, punch, kick etc. Target will receive boost in power when the ability activated. Needed 20 minutes to exploded. Life span are used as fuel for the bomb, the more life span used, the more stronger the bomb. Can be used on one target at the time, also usable on host.

After Sill drank the Fountain of Youth, he became an immortal. Life span? He got unlimited of that things. He's the guy who's rather choose gold than a silver, of course he took advantage on every single thing that he could. As far that he know, using own life as a condition to certain ability will make those ability super op. Like Kurapika who use his own life as a condition to his chain, Kurapika can kill Uvogin who's rumoured as the strongest physical body in Phantom Troupe.

Back to the fight..

20 minutes exchanging blow with Sill, Stone became panic again as he saw the crows on his shoulders began glowing some dark red light from the inside. Stone realized that Sill tried to distance himself from him, he don't know why, but Stone come to conclusion that was due the crows abilities. 

BOOOMMMM!!!

Before Stone could try anything, the two crows on Stone shoulders exploded at the same time making Stone left with his blood all over the stage. The stage only left with half of it. Some audience were injured by the stage stone splashing all over. Of course Sill also became the victim from that splashing but because of his regeneration speed, no could tell that he was also hurt.

"This ability quite op but it's takes to much time..*sigh* i need to make some more op ability if i want to fight with Meruem 'species' who's speed broke the porsche record". Study Sill in his mind.

After that Sill just continued create new abilities one after one. He keep fighting in the tower and always win on death match but when it comes to normal fight he will just surrender making him going up and down in those floor frequently. He does that cause he want some fighting experience and sharpen all his abilities. He want to challenge 251th but expel those thought after studying who he was. He was someone who's on par with Silva Zoldyck. Sill who's realize that he is not ready yet continued to sharpen his skill.

Two years has passed...
