Chapter 13: On Nami's Compatibility with Thunder and Lightning

Explorer, Gym.

"Phew... it's been an hour, it's over!" Nami breathed a sigh of relief, setting down the heavy dumbbells in her hands.

"I'm really tired, but this potion seems to be really effective. My strength seems to have increased a lot," she remarked, clenching her fist. Though a bit fatigued from the workout, she could clearly feel the effects of training with the nutrient potion.

Not far away, Rosen, who had also taken the nutrient potion and exercised simultaneously with Nami, set down the sword body equipment in his hands.

Glancing at Nami, whose body was soaked in sweat from the workout, making her white T-shirt almost transparent, Rosen couldn't help but evaluate her figure in his mind. "Her figure is good, but compared to her two years later, she still has a lot of room for growth."

Rosen opened his and Nami's personal attribute panel.

[Name: Nami]

[Swordsmanship Style: None]

"My vitality has increased by 500 again, but Nami, who used the E-grade Nutrient Potion, only increased her vitality by 10 points. Is it because of the different training methods or because the E-grade Nutrient Potion can only produce such effects?" Rosen pondered, propping his chin with one hand.

"Although it's only 10 points, if Nami continues to use the E-grade Nutrient Potion for training, her vitality level will reach Grade D. Then she can use higher-level nutrient potions. It doesn't have much impact," Rosen nodded to himself, then looked at the "Swordsmanship Style" column for Nami.

"Although you can obtain diffrent swordsmanship and increse swordsmanship realm by defeating the shadow swordsmen in the Enlightenment Room, it might be worth trying to actively teach Nami some swordsmanship. If she can adapt to a certain breathing technique, her strength will increase more quickly in the future."

With his thoughts sorted out, Rosen closed his and Nami's attribute panels and walked towards Nami.

"Captain Rosen, how do I look?" Nami asked with interest, smiling as she looked at Rosen.

"What do you mean by 'how do I look'?" Rosen chuckled. "Heh, Captain Rosen, you were staring straight at my body just now. It was hard not to notice that fiery gaze," Nami teased, tugging at her nearly transparent T-shirt.

"Youthful vitality, good figure," Rosen gave Nami a thumbs up, then took out another E-grade Nutrient Potion from the system space and handed it to Nami without waiting for her to ask for payment. "Consider this as your reward. Nami, you can continue training now. You can only use this type of nutrient potion twice a day. My quota has been used up, so I need to go to the bathhouse for a wash. I'll teach you some other things when I have time later."

Rosen patted Nami's shoulder and turned to walk towards the bathhouse, waving behind him.

"Oh, by the way, I'll leave the navigation to you. Don't let the course deviate suddenly, or we might arrive at Cocoyashi Village late at night," he reminded before disappearing through the bathhouse door.

Nami looked at the nutrient potion in her hand, then at the closed door of the bathhouse.

"Stingy guy, didn't you promise me this nutrient potion before?" Nami shook her head and rested for a while. After drinking the E-grade Nutrient Potion in her hand, she began the second phase of her training.

With Rosen absent, Nami simply took off her coat and started exercising in a cool and refreshing manner.

...

Some time passed.

Explorer, Bathhouse.

Rosen had half of his body submerged in the warm water, his eyes fixed on Nami, who was sitting across from him wrapped in a towel.

After a while, Rosen broke the silence.

"Nami, I'm not going to pay, you know?"

"I know, I know," Nami waved her hand nonchalantly. "Who asked this place to have only one bathhouse? After the training, this is the only place I can come to take a bath," she said, showing a carefree expression.

Seeing Nami's indifferent expression, Rosen couldn't help but admire her open-minded personality. Through the system, Rosen had already learned that Nami had increased her vitality by another 10 points.

Now, she was only 44 points away from breaking through to Grade E vitality. At this moment, Rosen couldn't help but think of the previous plan to teach Nami swordsmanship.

"Nami, are you interested in learning something new?" Rosen asked.

"Something new?" Nami's eyes lit up, immediately wrapping herself in a bathrobe and sitting closer to Rosen. "Of course, Captain Rosen, I'm willing," she replied eagerly.

With two bottles of nutrient potion consumed, Nami now felt that her strength had more than doubled compared to before. Now, she had a strong desire for training.

"Since you're so interested, and you have the Gonryumaru, which is a sword that controls thunder and lightning, why don't you try to master the 'Thunder Breathing'?" Rosen rubbed his chin, deciding to start teaching Nami the Thunder Breathing technique to see how well she would resonate with it.
