Overlord

"Haki is a latent power that everyone possesses, an innate ability. The vast majority of people never realize this power exists, and among them, Conqueror's Haki is something only one in several million people possesses."

Different types of Haki are divided into various forms based on the user's level of mastery.

The most basic form of Armament Haki is Coating. This form is the most common; by covering the surface of the body or a weapon with Haki—the most obvious sign being that the covered area turns black—one can enhance both attack and defense.

It is like equipping armor and weapons, and it also allows one to touch the physical bodies of Logia-type Devil Fruit users.

The next level is Hardening, specifically manifested as the Haki-covered area turning a shiny black, with the resulting increase in attack and defense being several times greater than simple Coating.

Intermediate Armament Haki allows the user to project Haki outside their body to strike enemies. In Wano Country, this stage is known as Flowing Cherry Blossom, or flowing Haki.

Advanced Armament Haki allows the user's Haki to enter the enemy's body and destroy them from within, much like the internal force found in martial arts novels.

Now, let's talk about Observation Haki.

Basic Observation Haki allows one to perceive the strength and emotions of others. For instance, gauging the strength of an enemy, sensing an opponent's emotions and thoughts, or detecting the location and number of objects outside one's field of vision, much like a radar.

Intermediate Observation Haki allows the user to predict an opponent's actions in their mind, effectively helping the user move and dodge.

As for Advanced Observation Haki, it varies from person to person depending on individual talent; some enhance their range, some can hear inner voices, and some can even foresee the future.

"As for Conqueror's Haki, I don't have it either. If you manage to awaken it in the future, you can study it yourself." Maynard glanced at Luo Ya and took a large gulp from his water cup.

"Once your injuries have healed, I will officially begin teaching you how to awaken Haki. With your current level of 'cutting iron,' it shouldn't take long for you to grasp Observation Haki, but your scrawny little frame needs more strength training for Armament Haki." As he said this, he flexed his biceps.

Luo Ya didn't know where Maynard had found the doctor, but he felt that his injuries were mostly healed, leaving only a lingering sense of fatigue. After eating dinner, he fell into a deep sleep once more.

The sky was still dim when Luo Ya woke up, right on time according to the biological clock he had maintained for five months.

He got up and stretched his body, feeling that there was nothing wrong, then put on his clothes, secured Scorching Cloud at his waist, and headed out.

"Up early, are we, kid? Hurry up and eat. Are you ready to enter hell? Heh heh heh." Maynard chuckled strangely while flipping the beast meat he was roasting.

Luo Ya rolled his eyes at Maynard, grabbed a piece of the roasted meat, and began to devour it.

After finishing his meal, Luo Ya looked at the large array of brand-new equipment surrounding him, his fighting spirit soaring!

Maynard introduced the function of each piece of equipment one by one before telling Luo Ya to start training.

"Every swordsman must have outstanding arm strength, but you can't rely on arm strength alone; you also need a sense of balance and core strength in your waist and abdomen. There is no future in swinging a sword relying solely on arm strength." As he spoke, Maynard stood up and performed a classic fitness pose: the Devil's Horn.

Coupled with his gleaming white teeth, it made Luo Ya think of a certain bowl-cut character in a bodysuit, and he felt a chill run down his spine.

"We start with arm strength, then the chest muscles, and move down to the waist and abdomen."

Maynard spoke while helping Luo Ya correct his improper form.

After a morning of physical training, Luo Ya's body was completely unresponsive, and the hand holding his sword was trembling.

"Kid, I have a secret technique that can train both Armament Haki and Observation Haki at the same time. I wouldn't tell just anyone who asked."

After saying this, Maynard tossed over a black cloth and gestured with his wooden sword for Luo Ya to tie it over his eyes.

"So, your secret technique is just letting me get beaten while blindfolded, right?" Luo Ya roared, his teeth turning into shark-like points.

"How can you call it getting beaten? I'm striking you with Armament Haki so you can intuitively feel the power, and the blindfold is to force you to sense it with Observation Haki. From now on, physical training every morning, Haki training every afternoon!" Maynard said with a look of righteous indignation.

Luo Ya sighed and resigned himself to tying the cloth over his eyes. He didn't know where that bastard Maynard had bought the cloth, but it was completely opaque; he couldn't see a single shadow.

Thwack.

Hiss! Luo Ya gasped in pain as Maynard's wooden sword, imbued with Armament Haki, struck his shoulder.

"As expected of the world's greatest swordsman, even a wooden sword feels so natural in your hands, tsk tsk tsk. You can't even block a single hit, Luo Ya? Should I use my feet instead?"

Maynard pouted and said in a mocking, sarcastic tone.

"Damn you, Maynard, I'll fight you to the death!" Provoked to the point of burning rage, Luo Ya grabbed his wooden sword and swung wildly in one direction.

"Luo Ya, anger can bring power, but you won't get far with anger alone. You must use your heart to sense my position and feel the flow of Armament Haki on the part of your body being attacked." As Maynard spoke, he leaped backward sharply. The blade wind from Luo Ya's swing ruffled Maynard's shirt.

"Was that anger faked? Tsk tsk tsk, trying to use the opportunity to sense my position and ambush an old man like me. Tsk tsk tsk, your body might be weak, but you're still quite something; you almost got my clothes dirty." Maynard brushed the dust off his clothes and tilted his head.
