Ch. 521Immortality's Secret
Chapter Summary: “Immortality’s Secret”
Key Plot Points and Events
- After being healed by Vergo and Mansherry, Ye Chen fully recovers and convenes his subordinates in the Kingdom’s council hall.
- The Beasts Pirates show no immediate response to Kaido’s defeat. Ye Chen orders an investigation into the mysterious figure who rescued Dragon and announces plans to attack the Beasts Sea.
- His primary objective is to obtain the Soul-Soul Fruit so that Hina and the others can be revived or awakened.
- In Caesar’s laboratory, Caesar and Judge examine the unconscious Kaido and discover the source of his extraordinary strength and apparent immortality.
- Their research reveals that Kaido’s body contains hundreds—or possibly thousands—of fused Lineage Factors, including human, giant, demon, animal, and other unknown bloodlines.
- Kaido is determined to be a genetically engineered or artificially cultivated life-form rather than a normal human or Devil Fruit user. His true nature may be that of a powerful Dragon, with his humanoid form being another shape.
- Kaido’s defensive barrier automatically appears when he is gravely injured. It cannot be pierced by Seastone, physical weapons, or Devil Fruit powers; abilities that touch it are neutralized.
- The group concludes that Kaido was likely created by the same mysterious individual connected to Dragon’s rescue and the earlier claim that Kaido was an experimental subject.
- Ye Chen reasons that Kaido is not truly immortal. The barrier must have a limit, and Kaido’s survival depends on its ability to withstand attacks. Since direct attacks, poison, and forcing Kaido to consume two Devil Fruits are ineffective, Ye Chen begins planning a method involving a Devil Fruit ability that can affect Kaido without directly touching the barrier.
Character Developments
- Ye Chen: Demonstrates strong leadership and strategic thinking. Although he relies heavily on overwhelming strength, he recognizes that Kaido’s unusual defenses require a more indirect solution.
- Caesar and Judge: Become intensely absorbed in their research, behaving almost obsessively as they uncover Kaido’s genetic composition. Their scientific excitement turns to frustration when they fail to break the barrier, though Caesar quickly regains enthusiasm at the possibility of studying Kaido further.
- Rob Lucci and Vergo: Remain focused on the broader mystery surrounding Kaido’s creator and the person who rescued Dragon. Vergo especially connects the evidence to the mysterious figure’s experiments.
- Tesoro and the others: React with shock and confusion to the scientific explanation, emphasizing how extraordinary Kaido’s origins are.
- Kaido: Remains unconscious but is steadily recovering, showing that his regenerative abilities are still functioning despite his defeat.
Significant Themes
- The limits of immortality: The chapter stresses that no power is truly absolute. Kaido’s “immortality” is revealed to be a powerful but limited biological defense rather than genuine invulnerability.
- Science and unnatural creation: Kaido’s body raises disturbing questions about genetic experimentation, artificial life, and the identity of the person capable of creating such a being.
- Power versus strategy: Ye Chen’s usual philosophy is that overwhelming strength solves every problem, but Kaido’s barrier forces him to consider indirect tactics and specialized abilities.
- Uncovering hidden powers: The chapter expands the mystery surrounding Kaido, Dragon, and the unknown experimenter, suggesting a larger threat beyond the current conflict.
- The danger of experimentation: Kaido’s existence implies that powerful beings may be deliberately manufactured, potentially allowing others like him to be created.
Important Character Interactions
- Ye Chen questions his commanders about the Beasts Pirates and assigns Lucci to investigate the mysterious rescuer.
- Caesar and Judge explain Kaido’s genetic makeup to Ye Chen and the gathered officers, while figures such as Bege, Tesoro, and the Big Bear King struggle to understand the findings.
- Vergo links Kaido’s condition to the mysterious person who rescued Dragon, reinforcing the theory that Kaido was an experiment.
- Ye Chen challenges Caesar’s belief that the barrier is unbreakable and proposes finding a Devil Fruit user capable of bypassing it, setting up the chapter’s cliffhanger: the identity of the person who can kill Kaido.
