"Finn, are you teaching me some skills?"
Luffy pointed to his nose, laughing in a straightforward manner.
"Although you're our eldest brother, don't forget that among the four of us, you're the weakest!" Luffy struck without mercy.
That was true.
Before Finn activated the system, he had been a total loser. Not even Ace, let alone Luffy, would have had trouble beating him.
"My idiot brother! But I'm not the same as before! Want to come out and practice some combos?" Finn said, deliberately taunting.
This silly little brother would definitely fall for it.
"Okay! But don't come crying to Grandpa when you get beaten up!" Luffy grinned at the challenge.
Luffy immediately shoveled the rice in front of him into his mouth, gulped it down, and wiped his mouth. He walked out to the open space near "167," still habitually digging his nose. He pouted at Finn and said, "I told you, strike first, or you'll never get a chance to fight back!"
"Alright, bring it on!" Finn wasn't polite, his body moving in a flash.
Advanced Shave!
In an instant, Finn appeared beside Luffy and raised his hand, smashing it into his head.
Boom!
"Ah!" Luffy cried out in pain, clutching his head. Damn, that really hurt!
"You're actually attacking?!" Luffy grumbled, still feeling the sting.
Unwilling to back down, Luffy extended his arms, shouting, "Rubber Gun!"
Finn dodged casually, then reappeared on the other side of Luffy.
Boom!
Another devastating blow to Luffy's skull.
"Hiss!" Luffy winced in pain, rubbing his head. "Mom! I've got two big bumps now!"
"Finn, how are you so fast?" Luffy was stunned. This wasn't the Finn he knew.
"Hey, want to compare some more?" Finn teased.
"Sure! I'll show you I can take you down!" Luffy clenched his fists, ready for another round.
"Rubber... Double Hit!"
Finn just used another high-level shave.
Boom! Boom! Boom!
Three blows in quick succession, each one sending Luffy's head into a whirl of dizziness.
"Ah! No more, no more!" Luffy stopped, holding his throbbing head and sighing in defeat. "Not fair..."
Finn laughed, approaching Luffy and patting his head. He grabbed the bumps on Luffy's head and said, "Hold still, let me fix that."
Medical Ninjutsu: Healing Jutsu!
A moment later, the bumps vanished.
"Huh? It's gone? That's amazing!" Luffy's eyes widened in surprise, his expression turning into one of awe.
"My silly little brother, does Big Brother feel strong now?" Finn patted Luffy's head with a playful smile.
"You're amazing! Really!" Luffy grinned, still in disbelief.
After all, he'd just had five big lumps knocked out of his head!
"Want to learn some skills from Big Brother now?" Finn asked, raising an eyebrow.
Luffy nodded eagerly. "Yes! Teach me!"
Finn, seeing Luffy's enthusiasm, was satisfied. He then activated a 100-fold Preaching and Karma Card.
"Using the 100-fold Preaching Card!"
Designated Ability: Eight Inner Gates!
Designated Character: Monkey D. Luffy!
Finn was about to hold Luffy's hand to begin teaching, but suddenly felt a slight discomfort. Taking his brother's hand to teach the Eight Inner Gates technique felt... odd. Besides, he didn't have the time to stay in Windmill Village teaching Luffy the technique. It would be far more efficient to let Luffy learn on his own.
He turned to the system. "System, can't I just teach him the method and let him practice on his own? Why do I need to teach him hand-on?"
The system responded, "Host, using two 100-fold Preaching and Karma Cards will strengthen the effect, allowing the designated person to learn without needing hands-on instruction."
"F**k, two cards?" Finn was annoyed by the cost but knew it was the best option.
"Alright, I'll do it!" Finn decided. After all, Luffy was his brother.
He activated the second 100-fold Preaching Card.
The next moment, Luffy felt a flood of information and memories fill his mind. His eyes widened in shock.
"Finn, there's so much in my head right now!"
"Of course! That's the Eight Inner Gates technique Big Brother just taught you! You can practice it directly through the knowledge in your mind! With this skill, Big Brother can let you confidently become a pirate!" Finn said proudly.
"Wow! Finn, you're so awesome!" Luffy beamed, overwhelmed by the newfound knowledge.
Though he was a bit dim-witted, Luffy quickly understood the power of the Eight Inner Gates and appreciated how much Finn had helped him.
"Stay still, Luffy. Don't resist," Finn said as he used another soul chain to bind to Luffy's soul.
Luffy instinctively tried to resist but then relaxed when Finn told him to open his soul's door.
"Finn, what's this thing? Why do I feel something different?" Luffy asked curiously.
"Idiot, you don't need to know the details. Just trust me and enjoy the benefits!" Finn replied, not bothering to explain further.
He then took out five attribute pills and said, "Open your mouth, I've got something tasty for you!"
Luffy obediently opened his mouth, and Finn fed him the pills.
After consuming the pills, Luffy felt an immediate surge in his physical stats, his strength, speed, and resilience all increasing dramatically.
"Wow! My strength, speed, and bounce! Finn, what did you give me?!" Luffy exclaimed, ecstatic at the changes.
Finn just shrugged. "It's nothing."
Rather than explaining, Finn moved on and found Dadan. He used a soul chain to share his infinite lifespan with her and gave her the same five attribute pills.
After spending a day in Keerbo Mountain, Finn left Windmill Village and set sail towards Shimotsuki Village, his super battleship cutting through the sea.
