To verify this discovery, Hoshino conducted an even more extreme experiment, cleanly severing Hidan's entire right arm.
"Hey! What are you doing?" Hidan felt uncomfortable looking at his arm that had been cut off.
Hoshino did not answer, but placed the severed arm on a tray a meter away and started timing.
Ten minutes passed, and the severed arm still lay there all alone.
Hidan's wound showed no change, but his arm remained as active as if it had just been cut off.
Hoshino said thoughtfully, "It seems that restoring the rules also has a limited scope."
Suddenly, Sasori manipulated Hiruko's tail to curl up the severed arm and roughly press it onto Hidan's wound.
"Hey! Be gentle! You lunatics!" Hidan winced in pain.
With a roar, the black patterns reappeared, but this time the connection speed was noticeably slower.
"The quality of external intervention can also affect the recovery outcome," Hoshino noted in his notes. "Rough assembly may slow down the recovery process."
"This recovery mechanism... is more like a rule of 'forced repair. 'Hidan's body is defined as 'must be complete,' but it requires external assistance to achieve this."
Scorpion said, "In other words, if you cut him into small pieces and scatter them everywhere..."
"Theoretically, he could remain in a 'crippled' state indefinitely," Hoshino continued. "He won't die, but he won't be able to move."
Hoshino and Sasori exchanged a glance and tacitly refrained from continuing the topic, but both understood that Hidan's 'immortality' was not invincible and had significant flaws.
"This ability!" Hoshino put away the experimental data. "It's clearly some kind of external 'contract' at work."
Scorpion said thoughtfully, "Just like his curses, they are all based on some kind of rule."
Hidan listened to their conversation and suddenly fell silent. He looked down at his newly reattached arm, a hint of confusion flashing in his eyes.
Hoshino keenly noticed this detail and suddenly asked, " Hidan, when you first discovered you had this ability, who taught you how to reattach your severed limbs?"
Hidan's expression suddenly froze.
"I... I don't remember..."
Sasori and Hoshino exchanged a meaningful glance.
"Interesting."
Recalling the characteristics of the " Death Controlling Possessed Blood " technique recorded on the scroll.
The requirement to obtain the target's blood, complete the ritual within a 200-meter radius, and ensure the blood remains viable... aren't these all manifestations of some kind of 'rule'?
"Your ability wasn't something you were born with," Hoshino said.
Hidan looked up, a hint of panic flashing in his eyes. "Nonsense! Of course, this was bestowed upon me by Lord Jashin!"
Hoshino ignored his shouting, turned to look at Sasori, and asked, "When the Akatsuki took him in, did they have any information about his past?"
"No, the Akatsuki doesn't care about that, but they did conduct a brief investigation later!" Sasori shook his head and said.
All we know is that he grew up in Yugakure, became a fanatical cult member when he was a little older, and later even destroyed the entire Jashin Cult himself.
"As for the source of his abilities... that's unclear!"
Hoshino continued, "I need to witness the entire process of ' Death Controlling Possessed Blood ' firsthand."
"Wait."
Hiruko's tail swayed gently, and Scorpion's figure quickly disappeared at the laboratory entrance.
Less than ten minutes later, Sasori returned, dragging a ragged, bruised-faced wandering ninja back. He had clearly been forcibly abducted.
Hoshino frowned, but said nothing, and turned to Hidan.
"Let's begin."
Hidan excitedly licked his lips, drew a black spear from his waist, roughly grabbed the wandering ninja's hand, and used the spear tip to cut a gash in the other's palm.
Blood dripped from the wound, Hidan immediately caught, letting out a strange laugh.
Then, he tilted his head back and drank the blood in one gulp.
Hoshino's prosthetic eye was fixed on Hidan's every move.
He noticed that the moment Hidan swallowed the blood, the familiar inverted triangle mark appeared on his chest, the black lines spreading out like a living thing.
" Your Lord Jashin, please accept this sacrifice!"
Hidan drew a strange circular diagram on the ground with his foot, then stood in the center, clasped his hands together, and showed a sickly pious expression on his face.
As the incantation was finished, his body suddenly turned black and white, and skull-like patterns appeared on the panel.
Immediately afterwards, Hidan picked up the spear and pierced his own thigh without hesitation.
"Ah!"
The wandering ninja on the ground suddenly screamed in agony as a bloody hole appeared out of nowhere in his thigh, gushing out blood.
Hoshino immediately activated the scanner, recording every detail.
Data shows that Hidan's Chakra is leaking out of his body in an abnormal way, only to disappear without a trace the moment it comes into contact with air.
It was as if we were being swallowed up by some invisible force.
Even more bizarrely, Chakra fluctuation identical to Hidan's appeared out of Hidan at the wound site of the wandering ninja.
It was as if this energy had traveled through some unseen channel and transferred directly into the victim's body.
"Ha ha ha ha!"
Hidan laughed maniacally and pierced his own palm with his spear.
The wandering ninja let out another piercing scream as his palm was also pierced by an invisible force.
Hoshino suddenly noticed a detail.
The blood at the wandering ninja's wound was an abnormal black color and showed no signs of clotting.
Hidan became increasingly excited as he played, and this time he raised his spear and pointed it directly at his own heart.
"The final blow!"
The data on the scanner suddenly went to zero.
It wasn't a malfunction of the equipment; rather, all Chakra was instantly and completely erased by some force, like pencil marks being wiped away by an eraser.
In contrast.
The moment the spear pierced his chest, the wandering ninja's body arched violently, letting out a final, heart-wrenching scream before collapsing completely.
"A perfect sacrifice!"
Hidan pulled out his spear, licking the blood off the tip with lingering satisfaction, as the black and white markings on his body gradually faded.
Hoshino quickly walked to the body of the wandering ninja and examined it.
The deceased's expression was frozen in extreme pain, and the blood vessels all over his body displayed eerie black patterns, exactly the same as those on Hidan's body.
Even more chilling was that the corpse was visibly shriveling and decaying, as if all its life force had been drained away.
Meanwhile, Hoshino's prosthetic eye also captured a startling detail.
A blurry inverted triangle mark appeared on the corpse's chest, a miniature version of the Jashin mark on Hidan's body.
The mark is absorbing the remaining energy from the corpse, emitting a faint, dark red glow.
"Interesting..."
Hoshino muttered to himself, and the moment his finger touched the mark, his prosthetic eye suddenly received a jumbled signal.
It was a blurry image.
Countless distorted figures knelt before a huge inverted triangular altar, while a blurry black shadow floated in the center of the altar.
