Luffy collapsed to the ground, looking emaciated and clearly exhausted.
"Thump! Thump! Thump!"
The heartbeat, like a drumbeat, started again, and Luffy's body began to swell up again, seemingly about to return to normal.
Without Senga thought, Chiga punched Luffy squarely in the left chest, and Luffy's heartbeat stopped abruptly.
However, Senga held back a little and didn't send Luffy away directly. This only made his heart stop for a few seconds, but it was enough to disable the so-called "Drum of Liberation" of the Nika Fruit.
Senga looked down at Luffy and said calmly,
"The sit-up routine doesn't work on me."
After the Drum of Liberation dissipated, Luffy also exited Nika Form. He opened his eyes and saw Senga's indifferent face.
He was so startled that he jumped up from the ground and shouted exaggeratedly.
"Thank you, Brother Qianqian!"
Ace and Sabo were both stunned for a moment; this was the Luffy they remembered.
Luffy stood still, staring at Senga with wide eyes, looking quite like a primary school student who had made a mistake.
Senga nodded. He roughly understood something. There must be someone else's will on the Rubber-Rubber Fruit, and this will has been subtly influencing Luffy, with an effect somewhat similar to Kotoamatsukami.
To be honest, Senga had also wondered if Naruto had been influenced by Asura's will. After all, it was a bit absurd that he hadn't turned evil despite being treated like that since childhood.
After being lectured by Senga, Luffy's body could no longer withstand the force, and he temporarily reverted to his original "idiot" Luffy.
Senga walked up to Luffy, who, despite his usual carefree Luffy, didn't dare to even breathe loudly. He couldn't help it; the impression Senga had left on him was simply too profound.
Looking into Luffy's wise eyes, Senga crossed her arms and asked,
"What, now you know how to call me 'Big Brother'? I thought you were trying to prove yourself earlier."
"Gulp... Brother Chiga, I don't know what happened either. I inexplicably started fighting with Ace and Sabo, and then I even attacked you. I'm sorry..."
Ace and Sabo walked over, supporting each other. Their eyes swept over Luffy, and looking at his two brothers who had been beaten into a beggar, Luffy suddenly wanted to laugh, but he didn't dare to. So he could only purse his lips and try his best to suppress his laughter.
However, his reaction was worse than a laugh. Veins bulged on Ace and Sabo's foreheads, their fists clenched tightly. Ace even forced out a sentence through gritted teeth.
"Luffy... aren't you proud of beating us up like this?"
"No, no!"
"Damn it! Iron Fist of Love!"
"Bang!"
Luffy spun away, feeling even weaker Ace. After landing, he couldn't get up for a long time.
He clutched the bump on his head and yelled.
"Damn it! That's Grandpa's move! Why did he have to teach it to you?!"
Ace snorted, retracted his smoking fist, and said,
"This move is one I figured out myself, and it's perfect for dealing with you!"
After saying that, Ace immediately performed a Sichuan opera face-changing act, looking at Senga with admiration and shouting,
"Brother Senga! You're finally back!"
Senga chuckled and patted his shoulder, saying,
"Long time no see, you've grown so much!"
"Hey-hey..."
Ace scratched his head and grinned sheepishly. Sabo, facing Senga up close for the first time, appeared much more reserved than Ace. He bowed to Senga and spoke respectfully.
"My name is Sabo, and I am currently Marine Rear Admiral!"
Senga nodded and said,
"I know you, Long's most capable subordinate. You're quite good; you're much more composed than these two."
Sabo was surprised to receive praise, and his face flushed with excitement after being told he was composed.
Ace, standing to the side, curled his lip, actually jealous of Sabo.
Sabo didn't notice Ace's subtle expression. Remembering Luffy's unusual behavior, he quickly asked Senga what was wrong.
"Wang, what's wrong with Luffy? He seems like a completely different person!"
Senga glanced at Luffy there and said,
"It's nothing serious, he's just possessed." As he spoke, Senga pulled Luffy towards her, then slapped him on the forehead and yanked him hard.
A white, humanoid Spirit Body was pulled out by Senga, and Luffy cried out in terror.
"Is this my soul!? Oh no! I'm going to die!"
Ace quickly stepped forward, grabbed Luffy's face, pulled it long, and roared at Luffy.
"Idiot! Do you look like you're about to die?!"
Luffy's face was distorted by Ace's pulling, and he said blankly,
"Yeah, I think I'm fine..."
Senga glanced at Luffy, her eyes looking at him like he was an idiot.
The Spirit Body that was being held suddenly struggled, and facial features appeared on its white face. It stared at Senga and spoke.
"You're in cahoots with the guys who helped Imu back then; it's you who imprisoned this world!"
Luffy was startled and shouted.
"I remember now, it's that sound! It's been ringing in my ears!"
The Spirit Body abruptly turned to look at Luffy and said,
"You are my successor; restoring the kingdom and liberating the world is your duty! I am guiding you!"
"What are you talking about? Who are you?"
"I am Joy Boy! I am the king of this world!"
Upon hearing this, Ace was displeased and rebuked him.
"What nonsense are you spouting! Brother Senga is the true King of the World!"
"He's just like Imu, a despicable thief!"
"Damn it! I want to..."
With a tremor of his hand, Senga caused Joy Boy's Spirit Body to instantly transform into countless white specks of light, completely dissipating into the air.
He clapped his hands Senga said calmly,
"They're all dead, so let them die. They might as well just give up now."
As she spoke, Senga glanced at Luffy. Upon being looked at by Senga, Luffy immediately got up from the ground and stood at attention again.
"Hey, you want to be a pirate again?"
Luffy was taken aback. If it were before, he would have answered "yes" without hesitation, but now he found that he didn't seem to want to be a pirate as much anymore. In the end, he just wanted to go on an adventure at sea.
He hesitated for a moment, then, under Ace's surprised gaze, he spoke.
"I... I don't want to anymore!"
Hearing this, Senga nodded in satisfaction, the arduous task of helping Luffy King Addiction was now successfully completed.
