How to kill people with immortality

Jiraiya is an extremely popular person. Since he decided to take Naruto out for training, he was not willing to be in trouble. So, he went to Kushina that night. Kushina didn't stop him, but just repeatedly asked Jiraiya not to hurt Naruto much.

Jiraiya left Konoha with Naruto the next day and began training for two years.

...…..

After they left, Yamanaka Ryo intended to take advantage of Korin to extract Chakra from Senju and Hyuga's bloodline this time. He wanted to take Ino–Shika–Chō children to Ninja World to grow and learn.

So after sending Kushina to Namikaze Minato, Yamanaka Ryo approached the Clan Leaders of Ino–Shika–Chō and Sarutobi Asuma to inform them of his plans. The Clan Leader had no comment on this. Asuma hesitated at first but eventually agreed. After all, Yamanaka Ryo was also a member of Ino–Shika–Chō clans. He had no reason to stop him to take his juniors to train.

After reaching a consensus, Yamanaka Ryo spoke to Tsunade and then created a special Ice Body Clone and made it stay at Konoha Hospital. He then took Ino–Shika–Chō trio on the road to travel to Ninja World.

.....

Yamanaka Ryo chose Hoshigakure as the first stop of his journey. The star at Hoshigakure is a meteorite with the power of Jūbi. Yamanaka Ryo hasn't experienced the power of Jūbi up close. Hence why he wanted to check whether there was any difference between the power of Jūbi and Korin.

Besides, Hoshigakure's Ninja strength was mostly average, so it's suitable for Shikamaru to practice his technique.

Yamanaka Ryo chose to not use his teleportation on this journey. Instead, he took the trio and slowly moved towards Hoshigakure.

Along the way, Yamanaka Ryo practiced with the trio using the Ino-Shika-Cho's Secret Jutsu and its combination with each other in various ways.

Before leaving, the Clan Leader of Ino–Shika–Chō told Shikamaru that they had to listen to Yamanaka Ryo during this trip, so they did not dare to resist even though they complained.

...…..

After a day of training, Yamanaka Ryo found a cave nearby and planned to spend the night there tonight.

After lighting a campfire with Katon, the four of them gathered around the campfire, and Yamanaka Ryo took something out of the Sealed Scroll and heated it up.

After they finished eating, Shikamaru suddenly asked, "Uncle Ryo, do you know who owns the Immortal Body?"

For a moment, Yamanaka Ryo wondered why Shikamaru asked this so suddenly, but he did not intend to hide it, and Hidan's affairs were not a secret either.

Seeing Yamanaka Ryo nodded, Chōji and Ino both seemed surprised. Shikamaru told them before that he saw the clansman of Uchiha buried a person who kept on yelling at the Forest of Death. They believed it but didn't expect it to be true.

The two were also interested in Hidan's situation, and now looking at Yamanaka Ryo.

Yamanaka Ryo laughed and said, "The Ninja of the Immortal Body was called Hidan. He, together with Tanigakure's missing ninja called Kakuzu, had invaded Konoha during the Chunin exam, but both of them were subdued by Lain. Speaking of which, in a sense, Kakuzu also had an Immortal Body. He can extend his lifespan by replacing his heart with other's hearts. "

"So if we can crush his heart, he would die?" Shikamaru pointed the key in Yamanaka Ryo's words.

"That's right! Compared to Hidan's Immortal Body, Kakuzu's Immortal Body's lifeline is his heart. Hidan's Immortal Body was created by this Jashin using thousands of people's blood as a sacrifice. He fused thousands of people's life force into his soul and body. No matter how much damage his body received, he will not die as long as the body can still be stitched together. "

"How can you kill him?" Shikamaru asked.

"There are probably three ways to kill him… First: Just like the Uchiha Clan, tie and bury him. In this way, he can not absorb nutrients so can't maintain physical function, and will die naturally. (Ps: This is what Kishimoto said. Hidan is dead because he can't absorb nutrients from the ground.) Second: destroy his body until it turns into a pile of powder, which will no longer be recovered. Third: Hidan was originally a monster made by Jashin using Evil Arts, so we can use him as another sacrifice. "

Chōji, while eating potato chips, asked, "Another sacrifice? What do you mean?"

"This Jutsu is called Edo Tensei. It is a Secret Jutsu created by Nidaime to summon the dead. But to summon the dead, a living person must be sacrificed. If Hidan is used as a sacrifice to Edo Tensei, I think he can also be killed. After all, his soul will enter the underworld and can't return."

Hearing such an evil operation Ino shivered. "Edo Tensei! To think there's such a Jutsu, Nidaime is really terrifying."

Shikamaru seemed calm, he said lightly, "It isn't that Nidaime is terrifying, but because of the war, Nidaime had to develop these techniques for clansman and village. Nidaime didn't have invincible power like Soudaime. To protect the village from the glare of the four Ninja Villages, some Forbidden Techniques are also necessary. "

Yamanaka Ryo patted Shikamaru's head and said, "I can't expect more from a man with an IQ of 200 or above, but one thing you didn't say right. Nidaime developed these Forbidden Techniques not just for the village, but also for another purpose."

"What is it?" Shikamaru asked.

"Nidaime wanted to control Uchiha Madara. After the Battle of the Valley of the End, Nidaime secretly put away Uchiha Madara's corpse. I think the original purpose of his Edo Tensei was to control Uchiha Madara, but he failed. But thanks to this failure, Nidaime noticed that Uchiha Madara was not dead. "

Explanation from Yamanaka Ryo stunned the trio. Everyone in Konoha knows that Soudaime had a duel with Uchiha Madara in the Valley of the End and killed him, but Yamanaka Ryo told them today that Uchiha Madara was not dead.

"Uncle, did Uchiha Madara really not die?"

Yamanaka Ryo nodded, "Not only did he not die, but also hidden in the dark and made a very unpleasant feeling, and you will understand these things later."

"Ah? Uncle, please tell us!"

"Aren't you smart? Think about what happened from the First Shinobi World War to today and see if you can find the answer." Yamanaka Ryo turned around and fell asleep, ignoring the trio.

Chōji and Ino didn't have Shikamaru's IQ, knowing that they could not think of anything, they went to sleep right away, leaving Shikamaru alone all night.

...…

The next day, They continued to move towards Hoshigakure, except that Shikamaru now had a dark circle around his eyes.
