" Secret Sound Transmission and Thousand-Li Sound Transmission over long distances are essentially the same application; the only difference is the distance between the recipients, hence the different names."
Developing this kind of application should be relatively easy; it just involves an extra conversion process—from sound to Haki and back to sound.
This sound doesn't come from the mouth, nor does it enter the ear; it's a dialogue between minds.
Imbuing something with fantasy is difficult; it requires considerable mental and Mind Power to weave the imagery you want to convey, which can't be done in a short time. Give it a try!
Vic previously developed the sound reception of Observation Haki by utilizing the propagation of the characteristic waves of Observation Haki.
The process involves converting sound into waves, receiving them in the brain, and then reconstructing them into sound. This time, the process is reversed, and it adds an extra step to increase the difficulty.
That is, after editing the sound in one's mind, the sound is converted into waves of Observation Haki and released, and then converted back into sound in the mind of the recipient, thus achieving the method of Secret Sound Transmission. Thousand-Li Sound Transmission is the same operation.
Vic already knew the principle behind it; now it's just an extra step. He just needs to make his Observation Haki more targeted, which means focusing more intently on the target of the sound.
So Barnett, who was sleeping that night, got into trouble. Vic didn't want to harm several girls, and since Barnett had a Devil Fruit to cheat with, who else would he harm if not him?
Various different voices appeared in his mind, which annoyed him greatly. He asked others, but they all said they didn't hear them. He was the only one who could hear them, and he even thought that the warship was haunted.
Because the sounds are simulated in the mind, they are diverse, including those of men, women, young and old, and even animal sounds.
Barnett was terrified; he called it the darkest and most helpless night of his life. Everyone else was perfectly normal, but he could hear everything.
People in the One Piece world are quite accepting of supernatural and ghostly beliefs; the vast majority believe in them. The existence of Devil Fruit with various special abilities further reinforces this belief, as many lack the scientific ability to explain these beliefs, leading to distorted interpretations as they are passed from person to person.
Vic chuckled to himself on the deck. This was a good way to scare people, and maybe he could even extract some information from them!
People would believe someone who claims to be a god; there are just too few novels in this world. Otherwise, anyone could claim to be a system and fool a whole bunch of people who dream about systems all the time.
After mastering the method, Vic focused on refining the voice library, aiming to create a diverse range of simulated sounds that were versatile.
Vic believed this skill would be incredibly effective in crucial moments, and then Barnett collapsed onto the bed, thinking he had gone mad from developing his Devil Fruit powers. He completely gave up and didn't move at all during the rest of the night.
" Barnett, what happened to you? Your eyes are so dark! Tell me! What were you doing last night?"
Early in the morning, Barnett cornered Wendy at the restaurant. Seeing Barnett's dejected appearance, Wendy was furious, thinking that Barnett had done something bad the night before and had been drained dry. This thought was very Wendy.
"Would you believe me if I told you I encountered a ghost last night? It felt like I was in hell, with a hundred ghosts walking around at night, all sorts of spirits whispering in my ear, and lots of animal noises, but I didn't hear any of them. The ghosts just kept talking to me, waah!"
Barnett looked like a pitiful child, and hugged Wendy tightly, which startled Wendy for a moment before she smiled.
Wendy had long harbored feelings for Barnett and had always wanted to win him over, but Barnett, like Vic, either genuinely naive or pretending, simply acted as if he didn't see her. This time, Wendy was overjoyed that he had taken the initiative to throw himself into her arms.
"Thank you to those ghost friends from last night, thank you to your entire family and ancestors for eight generations!"
Thankfully, Wendy only thought it out loud and didn't say it aloud, otherwise Vic would definitely send some ghosts to chat with her tonight, saying things about how she and Barnett weren't a good match, and also to disgust her, since she led Rebecca astray!
Vic didn't make his own breakfast; he ate at the restaurant instead. Hearing Barnett sound so aggrieved, like a child, he felt a little awkward and guilty.
" Barnett, don't worry, you probably just have too much yin energy around you, which is why you're attracting ghosts to chat with you."
"You need to be more masculine and spend less time with girls. Look at you, hugging Wendy right now. Isn't that just adding to the yin energy? They'll probably come looking for you again tonight," Vic said earnestly, trying to persuade you.
"Really?" Barnett instantly broke free from Wendy's embrace and ran to Vic's side. Wendy rolled her eyes at Vic, who had ruined her plans.
"Of course it's true! Think about it, weren't you the only one who encountered this last night? Didn't you spend more time with the girl? Think about it carefully!"
"That seems so. They're usually a group of men together, while I always have three girls of different ages around me. No wonder I got involved with them. I'll have to stay away from you guys from now on!" Barnett pointed at Wendy, Rebecca, and Ain thoughtfully.
The exceptionally intelligent Barnett was completely fooled by Vic, leaving Wendy somewhat doubting her judgment. Was this really the same man who exuded leadership qualities before?
Vic was overjoyed that he could fool someone as shrewd as Barnett. Actually, the main reason was that Barnett hadn't slept all night, was in poor spirits, and had slowed down his thinking.
Rebecca and Wendy both knew that Vic was lying, and Wendy was even more resentful that Vic had caused her to lose her embrace.
Ain paid no attention to anyone except Vic and was busy eating. Vic pushed Barnett away with a look of disgust.
"Alright, use your Devil Fruit ability to recover. To be honest, I was the one talking to you last night."
Vic stopped trying to deceive him and confessed directly that Barnett would be on his ship sooner or later, and it was better to say it now than later, as it would be more sincere.
"Really?" Barnett asked in shock. He genuinely couldn't understand how Vic had done it; it seemed unbelievable.
No one else heard it. Rebecca and Wendy looked at Vic with curiosity. They hadn't experienced Barnett's pain and didn't understand it.
"Of course, this is a new application of Observation Haki that I developed, which can send sound directly into a person's heart (actually, their mind), so others can't hear it," Vic said calmly.
" Vic, you really developed an Haki new app? You truly are a genius!"
I didn't quite believe you when you said you were going to develop a Haki new app; other apps take generations or even centuries to develop.
I never imagined you'd be able to develop it in your lifetime; I seriously underestimated you!
Barnett became a little fanboy again. Rebecca and Wendy were also shocked when they heard that it was an application of Observation Haki. It is difficult for most people to develop Haki in their lifetime, let alone cultivate Haki to a high level. It is really rare for Vic to have such an achievement at his age.
Vic didn't speak, but simulated several sounds in the minds of the group, which greatly surprised them.
"How can you make so many noises?" Rebecca asked, puzzled. Barnett and Wendy were also curious.
