Somewhere in the grand line.

In a cold island that was full of snow, coldness, a very strong monster, but no humans other than Garp and Lucas.

Garp took Lucas to a walk to the in this island. Today the lesson is about Haki. Mastering Haki is a necessity for anyone to say he is strong in this world for both devil fruit users and no users.

Garp took Lucas to stand above a frozen lake before stopping. Lucas stood in his place trying his best not to get affected by the environment. Every breath he exhales would make a thick smoky cloud to show how it's cold here.

"As I can see, you heard about the term of Haki, well, it's not that uncommon in the headquarter. Anyway, Haki has three types. Two are easy to unlock through training or awakening through some experience.

While the third type, the conqueror Haki is only accessible by one in million of the people...… "

Garp was explaining the three types of power that were called Haki. Haki is a power that comes from the will and the soul of the user, of course, the physical strength plays an important role.

Through the strong will, the Haki user would be able to access to the other two types.

The observation Haki where the user would be able to see and fight without needing the eyes, feel the enemy's locations and number, expect the attacks of the opponent even before they can do it. And at some high point of training this type. One may be able to see the near future for a short while.

The second type, Armament Haki, is an invisible energy, or armor to be more exact that can be wrapped weapon, the body or part. It made the covered part harder than metals and give the user the ability to hurt the devil fruit users.

Armament Haki can be used around the whole body. But the wider are you use it on the harder it is to control, so it's the best to use it around specific parts to assure more effect and control.

When the Haki is dense enough in a certain area, It would turn ink-black which means it's at the most solid form, of course, if the Haki isn't dense enough then the color won't change but the effect on the devil fruit users would remain. Garp showed this by lifting his fist then it suddenly turned to black ink.

As for the third type, which is the conqueror Haki, then it is so rare and can't be awakened by training alone.

It is some power that forces the will of the conqueror. Those who are exposed to it would feel their own will being crushed, those with weak will would lose consciousness and fall down.

Lucas knew about all of this. However, he pretended not to know and decided to listen more to Garp.

The knowledge from the manga is limited and he may forget some details. Besides, during reading the manga, Lucas had a habit of skipping the dialogues and drama pages, so it is better to listen to a true expert from this world.

Then Garp started to explain to Lucas how to use them. And the method of training the two. Once he unlocks them, then his training would be as smooth as Alvida's skin.

[Ding, Analyzing the armament Haki and observation Haki….

…..]

As Lucas was focusing on the sudden notification, Garp was recalling some even from some weeks ago.

In east blue, after visiting his grandson, Garp went to Calorina's office to acquire some information.

There he found about Lucas's who has very frightening potentials. At first, when he heard that he reached swords master level at 15 years old and in east blue, he felt it was amazing a bit, even if it's rare, things like this happen after training for many years, and most people start learning swordsmanship from young ages. But when he heard that he started to learn at age 15 and in a local Dojo. That was a bit frightening talent.

Not only so, but during a workout at her gym, he never complains about how hard is the training or show a hit of being pained even when his physical limits are broken but simply he would take a rest so his body recuperates then he trains again, he improved very fast due to that.

Hearing things about Lucas, Garp saw a talent. However, he thought that he has more potential which wasn't unlocked yet because he grew up in the safe east blue.

To unlock those potentials, he decided to put him on this island, where not only the monsters are more dangerous than +100 million bounty pirates. But also with inhuman weather.

After making sure that Lucas knew all of what he needs to know about Haki, Garp put his finger inside his nose:" Lucas, no matter what, don't go to the center of the island, there is a scary monster there which is beyond your level"

"Huh? Are you talking about yourself" Lucas was waiting for the system at any moment to unlock his Haki.

"Anyway, I'm going to take a piss, "

Garp turned and walked away.

Lucas frowned, this is the last thing he wants to hear.

After a half-hour.

[Ding, + Skill: Armament Haki lvl 1]

Ding + Skill: Observation Haki lvl 1 ]

[Ding, Auto cultivation function is unlocked for the two skills]

Feeling the first level, Lucas smiled. He felt like he gained some sixth sense that was still faint since he was in the first level. Lucas somehow felt some wind would hit hair the next second. And it did, except that he didn't feel the wind that hit his nose. Lucas wasn't disappointed since this is the first level.

After some time. Lucas lifted his arms with armament Haki. His arms didn't turn black, maybe since he just started and his control isn't enough to make is dense in a certain area.

[Armament Haki +90XP]

.

While training Lucas was gaining XP on Haki, and both of the types leveled up to level two. By focusing on the snow or the wind Lucas was able to gain more XP on observation while focusing on control the armament on a different area, Lucas was able to level it up. Now Lucas can control the Haki better a bit. But he didn't make his arm black yet.

Good news, after some time, as he focused on his fingertip, it started to change the color to ink-black for few seconds before it vanishes.

"My current level is low " After one hour, the snow started to fall down and the winds started to rage But Garp didn't return yet. Lucas smelled something fishy and his eyes were opened widely upon realizing something. Lucas jumped and started kicking the air bellow him so he can get up. When he reached enough height, he looked to the warship he came from.

It wasn't there. Instead, there was a letter on the ice that was written with the fists.

«Survive, Have some control over Haki, I'll Come back to pick you up a week later. Ah, and don't go to the center no matter what. Survive."

Lucas's face started to twist, Now he knew why both Ace and Luffy never wanted to become marines. It's because of their damn grandfather. Lucas yelled in some random direction "GARP, YOU BASTARD" he hoped Garp would hear him.

Lucas then descended to the ground, Luckily he has storage that has everything he needs to be it food, clothes, beds, and even a small house.

"Ghwaaa" Suddenly, a monstrous sound came not far away from Lucas. Lucas saw the creature that appeared, it was a rabbit-like creature with a length of three meters. It had long white ears with three horns, and a fat huge body that was full of fur and muscles. It had short legs yet big arms with long claws.

Lucas yell attracted this creature who is currently looking at Lucas as he is a new kind of food.

*Woosh* Suddenly the horned rabbit vanished and appeared next Lucas. It was really amazing speed, But Lucas was able to react in time and used five steps shave to appear twenty meters behind. However, The rabbit vanished again and appeared above Lucas, the rabbit slammed with his sharp claws, the beast was as fast as Lucas when using Shave.

Lucas felt this move with His Haki, and only this one. He used his arm that was covered by iron mass to block it. [Iron mass + 2000XP], It didn't do much damage, but he could feel some itchy on his skin when the claws made contact. Lucas took three steps back and quickly put his hand on his black sword that was hanging on his waist, but before he takes it, the rabbit vanished again to the back, but Lucas could clearly see it moving.

Taking this as a chance, Lucas used the assassination footwork [Stealth footwork] and vanished without making any sound.

"Gwahhh" The rabbit looked to the spot where Lucas originally was, but before he could turn his head, Lucas appeared behind the rabbit while his sword already pierced the skull.

"I've to admit, this rabbit is the strongest I fought so far

[+13.000 Acc.u.mulated XP]

[swordsmanship +5000 XP]

[Ding Observation Haki up to level 3]

*Gwaaah* *Roar*

Suddenly, around Lucas, many red eyes started to appear, there were many rabbits and one huge wolf.

All of them were growling and roaring. Lucas's hand clenched the sword and looked to the surrounding.

"Good XP"

*Roar* *Woosh* *Woosh*

The beasts vanished and appeared in the air surrounding Lucas, Lucas vanished as well while trying to keep track with them, it was a good exercise to his Observation Haki. Lucas no longer felt the coldness or the snow.
