After squeezing every last drop of value out of Miss Buckingham, Sig benefited greatly—mainly by obtaining another period of Vegapunk's research data. Combined with the data he obtained from Caesar Clown, Sig could be considered "the second person closest to understanding the principles of Devil Fruit."
In comparison, Ain's "Return-Return Fruit" was somewhat disappointing...
Judging from the scars on her legs, this wasn't true time manipulation. Otherwise, there would be no reason for Zephyr, after turning to the dark side, not to use this method to restore his youthful body, and even less reason not to use it to treat his arm!
After actual analysis, Sig discovered that its effect on humans and animals was less about manipulating time and more about being a "simplified Hormone-Hormone Fruit".
Through physiological regulation, it can instantly restore a person to a "youthful" state.
In this way, using this method to restore youth is closer to drinking poison to quench thirst and overdrawing one's life. The elderly may not be able to withstand it for long. As for using it to heal wounds... it is not without effect. It can indeed make "injuries that can heal themselves" recover quickly in an instant. However, the scars and old wounds that are meant to remain will still be left.
If the target is a Devil Fruit user, it is indeed possible to suppress the Devil Fruit ability. However, even if one "rewinds" to the time before eating the Devil Fruit, the Devil Fruit ability will not be Deprivation away; only the degree to which the Devil Fruit is developed will decrease.
Regressing to early childhood does indeed cause physical condition to deteriorate, making it more suitable as a control skill for enemies rather than a buff for allies!
The adjustment of items has no age limit; it's a "reduction" reaction. For example, the usability of the byproducts of combustion will be restored as much as possible to their pre-combustion state...
In terms of effect, it is closer to a simplified version of the "Alchemy Fruit"—that is, the fruit of the Red Clan Chef.
Since "time" wasn't involved, it wasn't very appealing to Sig. However, if one door closes, another opens; the other surviving Marine Sig had previously discovered also possessed Devil Fruit ability...
It was from the "Shove-Shove Fruit" Zephyr Sig could guess that he must be the other one of the two new recruits who survived the attack— Binz.
Sig felt that this guy's appearance, and the undergarment beneath his naval uniform, had a certain Wano Country style, so he specifically checked it out in his dream. He discovered that he was an orphan from the West Blue, and his parents were indeed "outsiders." Moreover, judging from his childhood memories, his parents' behavior did indeed have the shadow of Wano Country customs.
However, Binz's parents did not mention anything about Wano Country to him, so Binz knew nothing about it. He only knew some of the ninja techniques of Wano Country and had subconsciously accepted some of the Wano Country way of life.
The effect of the Shove-Shove Fruit is to accelerate, or even cause, plants to grow rapidly. In addition, this world has some special plants, such as those that Usopp encountered during his two years of training... Combined with this ability, it also has the effect of strengthening the resilience of plants, so it is actually not weak.
However, if it were a few months ago, Sig wouldn't have been too interested.
But now, these "Shove-Shove Fruit" are like a pillow delivered to Sig when he's feeling sleepy!
This perfectly complements the Tontatta people's planting abilities, allowing them to rapidly cultivate Devil Fruit carriers...
Although Sig cannot completely imitate his abilities, Sig has just been inspired by the research data in Miss Buckingham's memories, and now he doesn't want to focus on growing fruit properly, but has decided to try a different approach!
Then, Sig left the strongest possible Psychological Suggestion in Zephyr's consciousness—a deeply hidden Psychological Suggestion that wouldn't normally cause any abnormalities and required Sig to trigger...
Ain and Binz followed suit, but unlike Zephyr, Sig left a glorious and towering image in their hearts.
In their recollection, while they were unconscious, they vaguely saw Sig rescue them and bring them to the island, and out of consideration for their "good marine status," he didn't finish them off along with Zephyr.
Using this tactic on Zephyr might eventually be discovered, but Sig is confident in using it on the two "recruits," and can then use them to indirectly influence Zephyr.
As for Miss Buckingham and Whitey Bay, Sig naturally took them both with him. As for Zephyr, Sig was just using him as a side hustle, hoping to use him in crucial moments in the future. As for Whitey Bay, Sig had the expectation of subduing him, so he naturally couldn't leave him behind for Zephyr to vent his anger on.
A ship full of naval recruits—killing them is no big deal.
And what should Miss Buckingham do...?
We'll have to see what Whitey Bay can do with Sig!
If Sieg can completely straighten out and restore Whitey Bay's mental state, then Sig can subdue him. At that time, how to deal with Miss Buckingham, who caused him to become like this and used him for more than ten years, can be left to Whitey Bay to decide. If Whitey Bay's mental state is completely beyond saving, Sig can also indirectly control Whitey Bay by controlling Miss Buckingham.
Although Sig is now Sequence 6 "Hypnotist," Sig really wouldn't dare to guarantee that he could solve Whitey Bay's condition.
Sig previously thought that Whitey Bay's simple-mindedness might be due to a congenital disability or external injury, which wouldn't be a big problem for Sig.
However, it now seems that the real problem is that the "person" in front of us is no longer the boy who was used as an experimental subject, but a "creature" created by the complete loss of control of the Devil Fruit, which is equivalent to a smarter version of the Jailer Beast!
If it were an ordinary Devil Fruit, and it had gone out of control to this extent, it would now be in the consciousness of a "Devil Fruit." It's just that the "Devil" of Artificial Devil Fruit are also very primitive, which is why it looks silly.
This is not an illness or a trauma, but simply its inherent nature.
Therefore, in Whitey Bay's mind, he had no memories before the age of thirteen.
Sig could not undo his "loss of control." Analogous to the loss of control in the Paths of the Divine, even a true god could not reverse even Low Sequence loss of control...
Sig, along with Whitey Bay and Miss Buckingham, left on a small boat on a warship, and afterwards devoted most of his energy to Whitey Bay.
Three days later, Sig sighed...
As expected, all "healing" and "repairing" abilities were useless against Whitey Bay.
So Sig changed his approach...
Starting fourteen years ago, he reconstructed Whitey Bay's memories, making him believe that the first person he met after his "birth" was Sig, and then Sig took him to sail the seas!
To be on the safe side, Sig didn't completely replace his memories, but instead preserved his "real memories." This wasn't essentially to deceive Whitey Bay —because although Whitebeard wasn't very bright, his mental strength was sufficient, similar to Big Mom's previous poor condition. Relying solely on "deception" might lead to Whitebeard discovering it later, thus creating potential problems for Sieg.
Sig wanted Whitey Bay to discover, through comparison, that Miss Buckingham was using him, and that only "Brother Sig" was the savior...
