Luffy, how can you become the Pirate King if you don't work hard!

But... in this situation, shouldn't your mind be filled with knowledge, or at least with posture?

Nami climbed off him, and Luffy naturally breathed a sigh of relief, continuing his mental brainstorming.

What would have happened if things had continued as they were just now?

It's study time now!

If this continues, we haven't even reached the next step yet. In Nami's eyes, Luffy has probably already entered a state of enlightenment.

The thought of that scene sent chills down his spine. He longed to return to where he was, to the shameless, utterly unashamed person he remembered...

It's not the right time, and it's not the right place.

The price is—

Nami takes a bite and stomps on it, a smooth little combo that goes by effortlessly.

".....hiss."

Luffy was upset because he was attacked without his consent.

But looking up at Nami, her orange hair clung to her gradually paling face, and her white shirt clung tightly to her body under the rain, revealing faint traces of fabric that perfectly showcased the girl's figure.

"...Go change your clothes first, so you don't catch a cold."

It was rare to hear such words from Luffy, and Nami's expression softened slightly as she said:

"Before Zoro and the others return, you keep a close watch and don't let the pirates and the navy surround us..."

As she spoke, she thought of going back to her room to change her clothes.

Luffy readily agreed, but still followed Nami closely.

"...Why are you following me?"

"This... I want to learn." Luffy stared at Nami, his eyes clear and bright.

He can't live without Nami now.

But Nami remembered Luffy's reaction just now and the look in his eyes now.

It's probably because they saw the naked area that they had this reaction!

She rushed forward in a frantic manner and covered Luffy's eyes, yelling, "Close your eyes first!"

......

What kind of sea is the Grand Line?

Extreme weather like this is all too common; one moment it's sunny and bright, the next it's thundering and lightning. Of course, we can't rule out the possibility that it's caused by some kind of superpowered individual—if they have such an extreme ability to change the weather, that would be incredibly powerful.

Luffy was in Nami's room with a nautical logbook.

Zeff gave it to him in Baratie. There was a reason why Krieg wanted this logbook. Besides man-made disasters, the most important thing for pirates to guard against on this sea is natural disasters.

If they encounter extreme weather, let alone 5,000 people, even if the naval headquarters' warships come, many will die. They are afraid of natural disasters like earthquakes.

Legendary pirate crews, even the mighty Flying Pirates' fleet, were shattered by a single storm.

"Therefore, the legendary Battle of Ait Wall is a typical example."

".....right."

Nami sat in the bathroom, soaking in the warm water, and sighed contentedly. This knowledge was second nature to a navigator like her; everyone went through that phase growing up, and she had been through Luffy's too.

Many things can be considered the same thing whether you are interested in them voluntarily or passively.

Luffy is in this state right now.

[Your mental strength is severely depleted, but your willpower has increased, and your Observation Haki proficiency has increased by 1.]

Learning may seem like honey to Luffy, but it's actually more like poison. You say he loves learning? Don't be ridiculous. The only reason he can keep going is because some strange thing gives him a big stick and a date as a reward.

How useful is Observation Haki? Anyone who uses it knows.

"Achoo!"

Luffy rubbed his nose, leaned against the bathroom door, and seeing the slightly profound information, couldn't help but knock on the door and ask:

Are changes in deep-sea currents and vertical temperature variations in the ocean the cause of the emergence of large deep-sea organisms?

The sounds inside paused for a moment, then the bathroom door was suddenly pulled open a crack, and Nami poked half her head out, staring intently at Luffy. Her face was fair with a rosy glow, possessing a beauty like a lotus emerging from water. She bit her lower lip, her appearance both pure and lovely, yet also carrying a hint of coquettishness.

She took out a bath towel and patted it on Luffy, saying somewhat awkwardly:

"You idiot, are you trying to kill yourself by studying?"

"I'm in great health."

"What does this have to do with being physically strong or weak! A little wind and rain on the high seas can cause a serious illness. You studied medicine, how come you don't even understand this?"

Luffy took the towel, and a faint fragrance wafted over him. He looked up at Nami, whose face seemed even redder.

"Hey, stop doing those weird things!"

Chapter 54 Thunder and Rain

"But...it really smells delicious."

Luffy took the towel and brought it close to his nose.

He always speaks the truth.

The towel smelled exactly like the one on Nami.

A straight shot actually caught Nami off guard.

"Humph!"

Nami turned her face away, trying to appear calm. "Stop talking nonsense. You're soaked to the bone, hurry up and dry yourself off. I'm just worried you'll give me your cold."

Luffy took the towel, wiped his face haphazardly without any ceremony, and laughed, "I didn't realize Nami that you still care about me."

"Who, who cares about you!"

Nami instinctively retorted, but her voice inexplicably became weaker.

No, why would she feel guilty in front of this rubber idiot?

She cleared her throat, trying to regain her usual composure, "This is just a reward for accompanying me shopping today. It's just a reward, don't overthink it!"

She emphasized it a few more times.

After saying that, she retreated back to the bathroom almost as if fleeing, slammed the door shut, and leaned against the door, breathing softly.

Nami couldn't help but cover her burning face.

It's really hot in this bathroom.

Outside the door, Luffy shrugged and began to take off his soaking wet red shirt.

Is such a big reaction really necessary?

Water droplets slid down, leaving dark stains on the carpet in Nami's room. After drying himself off, Luffy belatedly realized that this wasn't his room.

There are no spare clothes.

He stroked his chin and thought for two seconds, then simply wrapped the towel around his waist, sat down on Nami's bedside, and picked up a nautical logbook from the bedside table to start reading.

Inside the bathroom, Nami was looking at herself in the mirror, her fingers unconsciously twirling a strand of orange hair that fell over her shoulder.

"That idiot."

Nami seemed to have thought of something, and chuckled and cursed.

Then, just as she was about to dry herself, she suddenly realized a serious problem—what she handed Luffy was the bath towel she had just used to dry herself.

To make matters worse, she hadn't brought any clean clothes with her in her haste!

"No way..."

She looked at the last small bath towel left on the shelf, a towel that could barely cover her body.

Nami bit her lip, hesitated for a long time, and finally wrapped herself in the dangerously short towel before carefully pushing open the bathroom door.

.....

After wiping himself off, Luffy quickly continued to immerse himself in nautical knowledge.

Compared to learning shooting from Usopp or cooking from Sanji, which are things that require being a craftsman.

He has recently chosen to study whenever he has to choose one of several options.

My knowledge of navigation has improved by leaps and bounds.

As for why?

Is it because she doesn't want to be a craftswoman, or is it Nami?

[Navigational Knowledge Experience +3]

[Navigation level upgraded to lv1]

[You have activated your passive talent, Temperature Sensing.]

[Temperature perception: Your sensitivity to temperature has greatly increased.]

Temperature sensing?

What's the point?

Luffy's hand trembled, and he belatedly realized that this temperature perception was a kind of Observation Haki.

[Observation Haki proficiency +1000]

[Observation Haki Lv1: 1080/10000]

"As expected, to some extent, these two similar powers will merge together. But how can this passive talent add 1000 proficiency points?"

Luffy had mixed feelings. Even after fighting so hard and suffering such mental torment, he only gained 80 points of proficiency.

But this also gave him a good idea.
