One Piece: The system is only activated after leaving the Navy.

As the Dragon Soar sailed at sea, Luo Tian strolled on the deck, his mind constantly pondering the distribution plan for the rewards given by the system mission last time.

As he walked, he secretly calculated the resources he had at hand.

After careful consideration, his first thought was of the crew's promotion cards.

Including the one I specifically kept before, I now have a total of four.

Anna and Angie's bodies need to resolve their energy issues, so two of the cards must be given to them to help them solve their problems.

After arranging Anna and Angie's share, Luo Tian began to think about the use of the remaining two upgrade cards.

"Dan isn't needed for now, and Yamato's current strength is sufficient. So let's wait until Tesoro obtains the Gold-Gold Fruit and then use it on him."

Luo Tian thought to himself.

Next, Luo Tian shifted his attention to his own abilities.

He was genuinely struggling with how to use the upgrade card he possessed.

In truth, deep down he longed to witness firsthand the immense power that the awakened Candle Dragon Fruit could unleash.

Therefore, he made a quick decision to use this upgrade card to upgrade the Candle Dragon Fruit.

However, just as he was filled with anticipation, the system mercilessly popped up a message: Unable to use!

Upon seeing this message, Luo Tian flew into a rage and roared at the system:

"Why? Why can't we use it?!"

As if sensing his anger, the system quickly responded:

"Host, to upgrade an advanced ability to its top level, you need three proficiency enhancement cards."

Upon hearing this, Luo Tian was taken aback at first, then shook his head helplessly. He thought to himself:

"Yes, no matter what, if it were really that easy to jump directly from advanced to awakened, it would be completely out of character for this broken system."

Since the plan to upgrade the Candle Dragon Fruit has fallen through for the time being, Luo Tian has no choice but to re-examine other ability options.

Recalling the recent battles, he suddenly realized that Conqueror's Haki was actually used more frequently in these battles.

Moreover, this powerful ability is practically invincible when it comes to clearing out those small fry, with surprisingly good results.

Therefore, after careful consideration, Luo Tian finally made up his mind to upgrade his Conqueror's Haki.

"Conqueror's Haki (Beginner) → (Intermediate)"

After this upgrade, Luo Tian clearly felt the surging power within his body constantly flowing.

He tilted his head back slightly, then slowly closed his deep, star-like eyes.

He stood quietly in place, like a silent mountain, exuding an aura of tranquility that was impossible to ignore.

Time passed second by second, and he kept his eyes closed, as if the whole world was isolated from him.

However, beneath this seemingly calm exterior, a fierce storm was brewing within him.

Finally, after an unknown amount of time, his eyelashes trembled slightly, and then he slowly opened his eyes.

In an instant, an incomparably powerful force erupted from his body!

This force, like a surging wave, rapidly spread outwards from him.

This is the enhanced Conqueror's Haki!

The sheer power and scope of its aura far surpassed anything seen before.

At this moment, Luo Tian was like a war god descending upon the world, inspiring awe and fear in all who beheld him.

At this moment, if anyone dared to stand in front of Luo Tian and look him in the eye, they would probably be overwhelmed by his powerful aura and unable to breathe, just by exchanging glances.

As his strength increased, Luo Tian's kingly aura became even more pronounced.

Just then, Luo Tian slowly withdrew his terrifying Conqueror's Haki.

In an instant, the numerous fish that had been swimming around the ship, as well as the enormous sea monsters, all seemed to lose consciousness, their bodies stiffening, before slowly floating to the surface.

The people on the ship immediately sensed the unusually powerful aura fluctuation. They all put down what they were doing and rushed to the deck.

Grandma Za stared intently at Luo Tian, ​​muttering to herself:

"This kid actually possesses such terrifying Conqueror's Haki, it's truly astonishing! Given time, he will surely become the most dazzling existence on this sea, his future is truly limitless!"

Dan, standing to the side, also looked at Luo Tian with surprise, thinking to himself, "The captain has gotten stronger again."

The beautiful and charming Hancock, however, had a face as red as a peach blossom, her cheeks as rosy as the sunset.

Her captivating eyes were fixed on Luo Tian, ​​and she said softly, "Brother Luo Tian is really strong."

On the other side, Tesoro silently watched Luo Tian, ​​a hint of envy and resentment in his eyes.

He murmured to himself, "If I could be as strong as him, perhaps I could have saved Stella back then..."

However, the forthright Yamato didn't have much time for sentimentality; she directly yelled at Luo Tian:

"Luo Tian, ​​come and fight me! Let's see who's stronger!"

Unfortunately, Luo Tian completely ignored Yamato's provocation.

He turned to Dan and instructed, "Dan, before these fish and sea monsters wake up, quickly catch some of them. That way, we'll have food for the next few days."

Upon hearing Luo Tian's command, Dan nodded in response without hesitation:

"Alright, Captain!"

Immediately afterwards, he called Tezzolo to join him in the effort, and they began busily catching the delicious prey floating beside the boat.

Luo Tian found Anna and Angie again, his face beaming with confidence and joy.

He walked quickly to them and said softly:

"Dear Anna and Angie, I've come up with a solution to the health problems that have been bothering you for so long!"

Upon hearing the news, Anna and Angie's previously worried faces instantly blossomed into bright smiles, as warm as the spring sun.

They looked at Luo Tian excitedly and asked in unison, "Really? Brother Luo Tian, ​​that's wonderful! Thank you!"

Before they could finish speaking, tears of emotion welled up in their eyes like a burst dam, sliding down their rosy cheeks.

The two sisters knew that if it weren't for the abnormal energy within them, their parents wouldn't have had to risk going out to sea to find a solution, and they wouldn't have encountered those terrible things.

Now that I know the problem is about to be solved, the emotions that have been suppressed in my heart for so long can finally be released, and the joy is indescribable.

Luo Tian looked at the two little ones crying like kittens and felt a pang of heartache.

He quickly stepped forward, opened his arms and hugged them tightly, gently stroking their little heads and comforting them:

"Don't cry, we're all family! And I promised your parents that I would help you overcome this difficulty no matter what. Don't worry, everything will be alright."

After hearing Luo Tian's words, Anna and Angie gradually stopped crying, obediently nodded, and replied:

"Yes! We believe that Brother Luo Tian can definitely do it."

Just then, Luo Tian mysteriously pulled two brightly colored candies from his pocket, smiled, and handed them to the two sisters, saying:

"Here, swallow these two 'miracle' pills, and your problems will be solved!"

But in reality, these two pills are just ordinary candies, a decoy created by Luo Tian to cover up the system.

After Anna and Angie happily accepted the candy, put it in their mouths, chewed it, and swallowed it, Luo Tian quickly activated the system interface in his mind and used the upgrade card on Anna and Angie without hesitation.
