Sinfull Life With The Strongest System

On an island that no human dares to live in cause the extreme cold weather and the strength of the beasts that live in. Currently, The winds were moving violently almost pulling the frozen trees from the ground. As for the snow, It was endlessly falling from the sky.

*Ghwaa* *Awoo* * Roar*

The surface of the island wasn't calm, Lucas with a black rapier in the hand was moving at extreme speed among tens of big-horned rabbits and one giant wolf, and apparently, the beasts had super speed as well.

For every few moments, a new beast would join.

Lucas was at a disadvantage giving the weather and the number which worked against him, and unlike humans and humanoid creatures, the beasts depend completely on their instincts in fighting which gives them high reaction speed and perfect timing and perfect choice of attacks.

[Observation Haki +…XP]. The system was gaining XP on Haki as Lucas was trying his best to keep track of all of those fast beasts which can't be done by depending on his eyes alone.

Lucas wasn't hearing the notifications either feeling coldness as he was focusing on dodging those annoying rabbits, especially that wolf which had large fangs that seem to be able to bend the steel.

*Woosh* * Woosh*

Standing in the middle, Lucas waved his sword while spinning his body «Itoryu: Tornado». From the sword, some compressed air blade spun around Lucas and made a tornado that surrounded him and attacked the bests in the air, the snow flew with the winds making a white veil that blocked Lucas from the view.

Some rabbits got injured yet this wasn't enough to stop them, those who got with light injuries and those who dodged stepped back and started running on their four limbs in a circle shape around the storm.

Using the few second time. Lucas quickly opened the system and put some XP in Observation Haki. But he didn't have time to level up his Armament Haki through acc.u.mulated XP as the tornado came to end and the monsters attacked again. Unlike games, there is no pause option in this battle.

But it was Ok, Lucas can level it up through battling.

[Observation Haki up to level 5]

As soon the tornado calmed down and the snow surrounding it fell, Lucas was attacked from every direction. Since he leveled up his Haki he could predict some attacks from blind spots, Lucas used his boxing footwork and created five after images that confused the beasts to attack. Following their instinct, they jumped on the afterimages.

meanwhile, Lucas was high in the air, he focused his Armament Haki on his sword and waved «Itoryu: Dragon cannon», from his sword. And blue sword energy made a shape of a dragon and flew to the ground.

*BAM*

[Armament Haki +8.000 XP]

[Armament Haki up to lvl 6 (0/7000)]

Lucas didn't have the time to overjoy with his XP, Instead, he was focusing on the remaining beasts, while he was descending. Lucas, legs turned ink-black. When he leveled up his Haki, his control over it became good enough. Lucas started to kick in the air sending sharp compressed air blades using the skill «leg storm».

*Bam*Bam* the beasts started to lose their positions.

Lucas used moonwalk and flew down with high speed toward one of the beasts. As soon he got close enough, he made a fist and used six king guns to shot a shockwave to the head that blew its head.

*Bite* but then the wolf bite Lucas's hand. "Dog" Lucas was about to use his free hand but then another wolf that came lately bite it and stopped him from using it, Lucas looked at both of them with a serious face. Despite having iron mass, those wolves fangs hurt him.

*Roar*. The remaining beasts used this as a chance and jumped on Lucas from every direction. Lucas let them jump on him. Now there was 23 that fell on him at the same time.

Lucas squatted and clenched his teeth. Then a shockwave was forming around his body. Using his whole body, Lucas unleashed the ultimate skill of the six powers «Six King Gun». *Bam* around Lucas, a shockwave was unleashed in every direction and it destroyed everything on its way in 10 meters radius.

The beasts that had direct contact with Lucas either died or defeated and lost consciousness, only those who were above their comrades survived with dangerous internal damage.

The time around Lucas became slower before the rest of the beasts realize what happened, Lucas appeared above them with his palm on their forehead while using the six king gun, the next second, they died and some lucky beasts survived but with an eternal brain Damage.

Lucas let them live on purpose since they can become a good XP cow in the future.

"That Brat isn't bad " Hidden in a high hill of this island and inside a warm cave, covered by the snow, Garp was eating some snacks while watching the fight of Lucas.

"He unlocked his Haki and both types, I'm amazed, that Calorina brat was saying the truth. His training now should be smooth since the hardest stage is to awaken the Haki'

Obviously, somehow, during the fight, Lucas managed to unlock some of his potentials and increased his skills to match the numbers of the beasts. Garp rubbed his nose while thinking. Lucas has more to unlock, he needs a dangerous life and death challenge. ' Should I do it... Should I'

'Oy, since when did he cook that wolf, was I thinking for too long '

Garp saw Lucas eating a giant wolf's steak. Since when did he cook it. It can't be that Lucas cook it when he turned his eyes, truly suspicious.

"How rude that smelly brat to eat while I'm trying to keep an eye on him"

Garp lifted a rock next to him, then, instead of aiming at Lucas, he aimed to the center of this island and threw the rock. The rock flew faster than a bullet and it hit something.

….

Lucas was enjoying his small meal which was a giant steak that made of the wolf he killed. He was eating fast as he never ate. The recipe he used was something to make the recuperation and using nutrition faster also to regain his energy.

*Earthquake*

*Roar*

The ground beneath Lucas started to shake violently. He heard many footsteps. Many of Rabbits and wolves started to appear in front of the blondie, Lucas looked in front and was ready to round two.

However, by the Haki, Lucas knew the beasts here weren't going to attack him, instead, they avoided him and continued to run. Seems they are escaping from something.

Lucas felt something amiss before the unknown thing come, Lucas used this as a chance to open the system and level up some skills.

[Observation Haki up to level 11 (0/100.000)]

[Armament Haki up to level 11 (0/100.000)]

[Shave up to level 10 (0/30.000) (one-step)]

Lucas didn't have more time to upgrade more skills neither he had the time to think wisely.

As the observation Haki was upgraded, Lucas felt like it should be good at the same level of the admirals or better a bit since it comes with the system. Lucas could feel now more things, like how many snowdrops are falling and where falling around him. As he focused further in front.

He could feel the existence that was coming toward him. It should be frightening since even the beasts that Lucas struggled with are running without thinking of fighting.

Lucas quickly activated adrenaline boost to enhance his abilities more than three folds.

"GHRRRRRR"

A polar bear-like is shown in front of Lucas with three 3-meters-sized rabbits in its mouth. It was an 8 meters giant bear with white snow thick fur. Its eyes were red as the crimson blood, as for its mouth it was full of long sharp fangs.

"Somehow, you remind me of an annoying Panda"

Lucas was reminded by Garp's words, never go to the center no matter what. Seems this is the final boss of this island.

"JwaghJwagh" The polar bear squeezed the two animals in his mouth and swallowed them. The blood was coloring his own chin. Hearing the human calling him annoying panda, the bear roared making a winds surge from his momentum.

Lucas's hair floated with the winds, even if he felt this bear is dangerous, even when his instincts told him to back off, he decided to stay. He has the wits and the system. Along with his collection of skills, as long as he is able to survive for long, then he would eventually win.

Well, if he has no chance to win, then, he always can use stealth footwork and leave the chat.

*Woosh* The bear charged at Lucas with high speed and slammed with its giant claws toward Lucas.

*Woosh* Lucas appeared in the air with his sword and hand being covered by the Haki, Lucas waved his ink-black hand at the bear, he was super fast and stronger with the adrenaline mode so this attack was super deadly for anyone that Lucas fought so far.

The bear felt the attack with his predator instincts and bent down a bit avoiding the attack, then it waved its giant claw at Lucas's hand with high speed.

Lucas tried quickly to react and jumped up, but as his sword clashed with the claws, it made a spark, metal clash sound, and a shockwave. The claw was cut as for the sword, the force made it fly back and was about to pull Lucas with him, so Lucas let it go.

In the air. He clenched his right fist, he was using Iron mass technique which made his fist stronger and harder than steel, above that Lucas cover it with Haki which made it black. Lucas used the moonwalk with a shave and kicked the air to appear in instant in front of the bear's stomach. he punched and unleashed his straight. «Prince straight: unleash three folds a punch with all of the body and strength focused on the right ».

As the bear took the punch, strong winds surged behind him and pulled the snow from the ground, the bear went five meters back, however, his soft fur and belly reacted as wave and shook for some time before stopping. Seems that the skin of the bear was soft enough to absorb the hit. Lucas opened his eyes as he realized that, but then the bear was in front of him with his leg kicking toward Lucas, Lucas quickly reacted and used moonwalk to down and avoid the kick, but then, the leg change its direction in the air and hit Lucas.

Lucas covered his right arm with Haki and used it blocks while his left arm was extended with his fist pointed at the bear's nose, at the moment he was kicked a shock wave left his left hand.

*Bam*

[Six King gun +2000 XP]

[Iron mass +14.000 XP]

[Armenant Haki +4000 XP]

Lucas hit the ground violently and all of the snow flew up, as for the bear, it took some steps back while covering its nose.

"This is painful"

Lucas's right arm was pulled off while a wound appeared. While being buried in the ground, Lucas put his left hand on his right arm and used massage hand lvl15 and started rubbing in hope that he fix it, soon the wound was closed and the bones were rejoining again.

*Roar* Lucas saw something falling at him from high, it was the bear's b.u.t.t, Lucas frowned, he quickly reacted and avoided the b.u.t.t that was going to crush him by jumping back.

Lucas used stealth footwork and started running at a crazy speed, he was moving in a circle shape around the bear trying to confuse him and his sense. The bear was following closely, he felt dizzy as his eyes couldn't keep with the blur that was running around him. He slammed with his paw, but it missed and Lucas shot a small shockwave from his hand at his nose. The bear jumped up high and decided to hit the ground to make the ground shake, Lucas could see this with his Haki and jumped at the right moment...

And so, a full day and night passed while the two were fighting.

'The Brat didn't run. Well, he is braver then I think. I wonder if he is aware that his skill is increasing, the same for his Haki control at an amazing rate. In my whole life, I never saw a marine like this, expect my self bwahaha.

I have to be careful, he has been fighting for long so his body is tired '

"Should I eat my snacks" Garp didn't smile and kept watching. He must be careful while watching Lucas interfere at any moment, any delay from him could lead to Lucas's death.
