Babysitting Whitebeard’s Crew:How I Accidentally Became a Teen Emperor

Lucas marvelled at the profound mysteries of his newly mastered skills. Each ability had ascended to a level that redefined its potential, leaving him teetering between awe and exhilaration. 

The profound meaning of Tekkai—Steel Block—didn't seem particularly special. Its essence was simple: turning iron into steel for an even tougher defence. 

But Lucas couldn't help but laugh. "Whoever uses this, dies..." 

The notorious Tekkai debuff was well-known among pirates. Even the enhanced Steel Block wouldn't save its users from inevitable defeat. 

Why rely on this when Armament Haki made Tekkai entirely obsolete? Lucas had no plans to waste his time with it. 

The profound meaning of Shigan, however, left Lucas intrigued. 

Spear Fighting: Shigan transformed his finger into a high-speed projectile launcher, curving the trajectory of the attack with advanced wrist manipulation. 

He turned his attention to a flock of seabirds flying nearby. 

"Let's see how you handle this!" 

He focused energy into his right index finger, gathering immense pressure. With a quick thrust, Lucas executed the technique. 

"**Spear Fighting: Shigan!" 

A powerful air bomb shot forward, but instead of travelling in a straight line, the attack curved unpredictably in a wide arc. 

One seabird, sensing danger, froze in mid-air. Its instincts screamed that the end was near. 

But instead of hitting it, the attack veered sharply. 

Boom! 

A seabird farther away cried out as it was struck, falling lifelessly into the ocean. 

The first seabird blinked, stunned. It turned to its flock as if to say, "This human is a monster!" 

The profound meaning of Observation Haki, Future Vision, allowed Lucas to see several seconds into the future. This ability had already been demonstrated in the original series by Katakuri of the Big Mom Pirates, who mastered it to perfection. 

Now, Lucas possessed the same gift. 

The profound meaning of Armament Haki, Internal Destruction, opened a new realm of possibilities. 

Armament Haki typically had three levels: 

1. Hardening: The basic form, reinforcing the user's body or objects. 

2. Entangling: Wrapping Haki around oneself or weapons for enhanced attacks or defence. 

3. External Release: Releasing Haki outward to create shockwaves or barriers. 

But Internal Destruction went beyond. 

By penetrating the target's surface, this technique directly attacks its internal structure. It could bypass even Kaido's legendary defence, dealing devastating internal damage. 

Finally, the profound meaning of Conqueror's Haki, Entanglement, elevated his dominance to godlike levels. 

Conqueror's Haki, in its raw form, could incapacitate thousands. But entangling it condensed this overwhelming energy into a focused point, amplifying its destructive power. 

With his arsenal of profound meanings and techniques, Lucas realized something startling. 

In one-on-one combat, there were few who could rival him. His mastery of Rokushiki, combined with his upgraded Haki abilities, made him a force to be reckoned with. 

Unless an enemy wielded a Paramecia Devil Fruit with bizarre, rule-bending powers, Lucas could dominate most opponents. 

And like Kaido, he could now act with unparalleled audacity.
