Sinfull Life With The Strongest System

In a frozen island, Lucas was fighting a giant polar bear.

Lucas was chest n.a.k.e.d, there are some blood traces on his body and his face.

The bear wasn't in a better state either, he took many of the high leveled six king gun that surpassed his defenses and harmed him from both inside and outside. The bear had blood traces all over his fur, this fast human was the most annoying thing he fought in his life. also, it had a body harder than steel, he felt that the body become harder and harder when it gets hit.

Lucas was tired, really tired, he had been using Adrenaline boost for a long time and fighting with a strength that surpasses his usual power for too long had put a huge burden on him. Even with all of his inhuman stamina, his body would give up at some point if this went any longer.

Luckily, during this battle, Lucas managed to level up some skills. Six king gun leveled up two levels in the row since Lucas used it most. Now he can create a larger and stronger Shockwave, he can control the shockwave better now. The rest of the six powers leveled up the fastest since they have a triple XP buff. As for the rest, then it would be his footwork. Adrenaline boost has leveled up two levels as well making his power go higher and higher.

"This battle is about to end" Garp from far was observing carefully with his eyes tight. Things are about to end. Lucas did his best and even surpassed the expectations. But sometimes, humans should accept their limits and not push too far beyond.

On the white battlefield, where the snow is still descending.

The bear appeared next Lucas and kicked with its feet. Lucas took the hit with his chest and went back some meters. Lucas took some light damage yet his body seems to be fine and hard. During this day, his Iron body leveled up once more, now it only needs a few amounts of XP to level up.

[Ding, observation Haki up to level 12 (0/300.000)

Extending the range of Haki

+ the ability to see the near future for a short while.

Cooldown 20 seconds ( can be reduced with leveling up)]

Lucas suddenly felt his Haki suddenly became stronger, for a second, he felt some actions would happen for the few next seconds, it was blurry images, how the bear would move, where he would aim and how will both of them react.

But they had yet to move. It was something that would happen in the near future. Too bad that he needs 20 seconds to use it again.

'I have to end this now' Lucas Dashed and jumped, the beast reacted as Lucas expected.

The bear slammed with his paw again, Lucas kicked the air bellow him avoiding the hit, then he landed on the arm of bear and ran few steps. The bear used his other hand and stroke the human-like a bug. Lucas already knew this, he jumped and landed on the bear's head.

That second. A Shockwave formed around Lucas's left leg, it took a shape of a faint sphere that was visible a bit before unleashing, then in a part of a second, six king gun was used and the shockwave stroke the bear on the head. Lucas used the momentum to jump to a specific spot.

The shockwave was very strong compared to the last day attacks, this was the result of leveling up. The bear fell down on the ground with his stomach.

A wide and deep hole appeared as it was the mark left by Six King Gun. The giant bear was small compared to the hole he was buried in. He held his head with both of his hands in pain and yelled. One of the bear's eyes exploded while he started to bleed from his nose, eyes, and ears. He never expected that the human would finally step on its head.

The bear roared more and went berserk mod. Currently, his brain's cell was destroyed, however, he still alive and moving based on his instincts.

*Woosh*

Lucas appeared in not so far spot, it was where his sword was buried. Lucas lifted his sword and held it tightly. He turned his head and looked to the hole where the bear climbing out when it was done climbing, it adjusted itself on his four limbs, it seems like the beast went berserk.

Lucas's eyes started to get tight, his fighting spirit was rising. His fighting spirit started to materialize. Lucas held the sword with both of his hands. The snow around him got pushed off as an invisible aura covered him.

Lucas opened his arms widely while holding one sword. As his hands were separated, two swords appeared in each hand. The snow started to melt around him and turn into water that started to boil and vaporize. From the two swords, a small fire crawled on the blades and flew to his back. Then the fire extended and made two large wings made of yellow flames. Lucas's sword aura appeared finally after his fighting spirit rose.

Garp saw this and opened his eyes widely, in this world, there are few swords user who can make their fighting spirit materialize , one of them was a commander of a sea emperor that could make petals to attacks…

«Imperial Aura: Holy Phoenix » apparently, those flames wings and the additional sword was an illusion made by his soul and fighting spirit. However, the effect of those is real.

*Roar* The bear dashed this time with stronger momentum than ever, since it went berserk it became faster and stronger.

Lucas squatted and crossed his arms, as the bear got close enough, he opened his arms and waved the two swords «Two sword style (Nitoryu): Flaming tornado». Compressed air blades flew out the swords and made a big tornado, as the winds clashed with the air and got covered by flames.

The fire tornado flew forward and hit the beast. It was huge that it made the bear look small, the bear's body was getting burned and cut. "JGHWAA" The bear glide back 40 meters while trying his best to push back. Big wounds started to appear on the chest that got cut by the wind, then the wounds along with the fur got burned by the fire.

"WAAAA" when the tornado stopped, the bear let a shriek of pain, his fur was on fire, so he quickly started to roll on the ground trying to make use of the ice .

Lucas didn't waste a second, he jumped high while the wings behind him flapped to increase his speed up. When Lucas got 30 meters up in the air, he lifted both of the swords and waved with all of his strength «Two swords style: Phoenix mod – Dragon Cannon ». Huge sword energy left Lucas's sword and made a huge Dragon shape, it was the biggest Dragon sword energy that Lucas shot so far. When the sword energy made contact with air, yellow flames raged on the dragon sword energy and made a yellow flames Eastern Dragon with 30 meters length.

The bear whose fur turned black from the flames of the tornado looked to the coming flames-dragon with eyes full of fear. As soon it got close, The bear got cut in half, soon the fire wrapped itself around him and burned it

*BANG*

The collusion of the Dragon sword energy with the ground made a Big Impact that destroyed hundreds of meters around. A big explosion occurred and flames covered the landscape. But since the snow melts and turned to water, the flames started to turn off.

*Breathing heavy *

As the flames calmed, Lucas landed on the ground while trying to breathe slow. The snow started to fall again on him.

The sword in his left hand vanished into thin air, the same for the wings, they vanished.

[Swordsmanship up to level 12 (200.000/500.000) (half-step middle stage swords grandmaster)]

[Ding, Killing frost island king, Polar bear]

[+ 1.000.000 acc.u.mulated XP]

[Armament Haki up to level 12]

Hearing the notifications, the chest n.a.k.e.d Lucas finally made a smile. 'Good amount, I wonder where the island where Luffy trained for two years, there should be some strong beasts as well'

Lucas deactivated the Adrenaline boost. But then, suddenly, a huge amount of blood got out of his mouth. He has been fighting for too long using a power that surpasses his level, so there would be some price. Lucas fell down with his back on the cold ground. In Lucas's hand, a bottle of water appeared, Lucas struggled and used a bit of the strength that left and put it in his mouth. As he drank a few droplets, the bottle fell from his hand

'Cold, So cold '

'Things would be warm If Nami was here... Sigh, with her long legs, I would feel warm again. Or at least Kaya's soft body or…. ' Lucas closed his eyes while thinking about good things.

"Let's go back "

Lucas opened his eyes slightly to see Calorina standing over him.

He smiled and decided not to think too much, this is a dream so yeah: "Maybe, one kiss and I'll get up"

Calorina made a frown:" Oy, Smelly brat, Do you want to kiss my fist to get up "

"Huh? " Lucas's face made a question mark. Why is she talking like Garp

Garp was standing next Lucas. Because Lucas was very tired, he thought Garp was his cousin. Lucas said with a faint voice " even... If you act that way... I still like you... Zzz"

Lucas said those words to what he imagined his cousin, but who heard it was Garp. Garp was heart touched. Seems that Lucas actually didn't hate him for leaving him to death on this island, yet he said he liked him. Seems that Lucas appreciates his good intentions for training him.

Garp lifted the sleeping Lucas who was only 15 years old in his eyes with a proud expression. Garp was trying to hold back his tears of happiness.

"Bwahaha, finally, someone understands. This how good marine should be " Garp lifted Lucas back to the ship while thinking about his son and grandsons who didn't understand his ways.

...

A day and a half later.

MarineForde. Inside the headquarters' hospital.

On a bed, Lucas was sleeping with his upper part exposed, it was covered with some bandages. His body was connected to some medical kit that was providing him with nutrients.

Earlier Doctor said that Lucas was exhausted to the extreme with some internal injuries. But his condition isn't serious and he would be able to heal soon.

The doctor was amazed at how hard the youth's body, he tried to use needles on Lucas's body but it broke, apparently, this is the first time someone uses iron mass while sleeping. They waited until some swords master came to help.

Lucas opened his eyes, he bent his body up and stood straight. He stood with his body sore. Around him, there were some medical kits and some tubs attached to him. Seems they put some drug to make him sleep. Lucas took the tubes off with his hands.

Just what happened. He put his palm on his head, soon he remembered the crazy death fight he took on that island. Lucas's hands started to shake from anger. "Damn you, Garp "

"Oy, Smelly brat, is this how you thank me. By the way, you could have an advantage at the beginning if you didn't aim that punch on its belly since it is too soft. But well, We can always repeat that. " Garp had a large grin on his face.

'Repeat your ass' Lucas frowned, then he closed his eyes and lied down on his back. There is nothing he wants more to kick Garp.

'But that wasn't bad. Many skills leveled up, let's test this one '

Lucas's hand turned ink-Black as he pointed to Garp. He was about to use six king gun, maybe he should aim at the balls for more pain, but then a sound interrupted.

"Lucas are you Okay, I was too worry"

Lucas turned his head to see Garp sitting next to him, Lucas showed a deadly gaze. Next Garp, Alvida was there as well with an anxious expression on her face, then Lucas's expression calmed down.

"No need to worry, when I see you, I turn fine " Lucas smiled. Then his stomach started to shack.

"Brat. She has been staying here from the last night " Garp said. Alvida lowered her head, she had been here since the last night, at first, she was angry that Lucas didn't show up for more than two days. But then she heard Lucas was in the hospital, her anger became wariness and she stealthy took a ship to come here.

"Hey" Lucas ignored Garp.
