Impure World Reincarnation means that the dead can be summoned into the real world in some way.
The contract scroll of Ryūchi Cave means that Sage Mode can be learned from White Snake Sage.
These two are what Allen wants most, and they are also things that must be obtained.
Especially the former. Although Sealing Scroll records the methods of learning and cultivation, the problem is that it uses many words that only people in this world can understand.
He couldn't understand even a single word of the extensive description of Pure Land.
This is why, in the end, only Orochimaru and his subordinate Kabuto mastered the ninjutsu Impure World Reincarnation.
Because among all Naruto World, only Orochimaru is the most dedicated to breaking the boundary between life and death, so he must have secretly done a lot of investigations and research on Death, Pure Land and the like.
In the process, he gradually understood and understood what the afterlife was like, and what Root was that could make Impure World Reincarnation successful, and finally allowed the ninjutsu invented by Second Hokage to reappear in the world.
For Allen, the combat effectiveness of the strong men from Impure World Reincarnation is secondary. The key is the knowledge and ninjutsu they mastered.
Out of desire for the unknown power of Nen abilities, Orochimaru, although a little reluctant, finally agreed to the deal.
After getting the advanced application, attribute testing and development skills of Nen abilities, he quickly handed over the contract scroll of Ryūchi Cave and the specific use method of Impure World Reincarnation.
As for the principle...
Sorry, Allen has no interest in this, nor does he want to know too many secrets about the afterlife.
He just needs to know how to summon the dead.
In the following days, the two of them lived in peace and went about their own business. It was not until almost a month later that a secret letter from Root Organization broke this tacit understanding.
"Haha, what does Danzō want you to do?" Orochimaru asked in a slightly mocking tone.
He really wants to know now what Danzō's reaction would be if he knew that one of his most trusted subordinates had betrayed him long ago and reached a cooperation with him.
Allen casually left the two letters on the table and replied with a chuckle, "It's nothing more than Kakashi taking the newly established Team 7 to leave the village and go to Land of Waves to perform a mission. And in this Genin Squad, there are both Uchiha Clan's last orphan Sasuke, and also Sasuke. Nine-Tails Jinchūriki Naruto Uzumaki. What he means is for me to find an opportunity to kill Sasuke, and then frame it on you or others, while protecting the village. The safety of war weapon Jinchuriki. Who made Land of Rice relatively close to Land of Waves, and my recent report shows that there is no change in you for the time being."
"Oh? Put Jinchuriki and Uchiha Clan's orphans in the same team. Is Old Man Hiruzen playing that boring ninja game of bondage again?" Orochimaru pursed his lips with a playful expression.
Allen nodded slightly. "Yes! Hasn't he been doing this all the time? Using the most fragile human emotions as a kidnapping, tightly binding the fate of two to three people so that they cannot easily escape the control of the village. I have to say, this This approach is really despicable. Unfortunately, it doesn't work for everyone. And the old man doesn't understand that using emotions to maintain a person's loyalty to an organization is the most unreliable thing. Only interests, and only interests, can unite people in the same camp."
"You're right! Common interests are the prerequisite for cooperation, just like the two of us. But do you really plan to kill Sasuke Uchiha?" Orochimaru cautiously probed.
"No, of course not. Because I know that he is your prey. But no matter what, I am still Danzō's nominal subordinate, and the show still has to be played." Allen said his plan casually.
"Then what are you going to do? You know, acting in front of Kakashi is not an easy task."
Hearing that the other party would not actually kill Sasuke Uchiha, the expression on Orochimaru's face immediately relaxed a lot.
Otherwise, he couldn't guarantee whether he could keep this precious and rare reincarnation container.
"It doesn't matter! Anyway, before your plan is launched, I don't plan to return to Konoha for the time being. So it doesn't matter what the higher-ups think. All I have to do is pretend to be completely obedient to Danzō's orders."
After saying that, Allen stood up and stretched his muscles, went straight to the training field next door, and waved to Karin who was undergoing actual combat training.
When the latter saw it, he stopped quickly, hurried forward and asked, "Sir, do you have any orders?"
"Pack up, we will leave for Land of Waves in ten minutes." Allen answered straightforwardly.
"Got it!"
Karin nodded vigorously, then quickly ran back to the temporary rest room, simply wiped off the sweat on his face and body, and put on the leather armor that could greatly increase strength, reaction speed and physical fitness, and put on a purple coat.
Looking at herself in the mirror who was already quite slim, she adjusted her glasses and murmured to herself in a voice that only she could hear, "Come on! Karin! Seize this rare opportunity to be alone! You can definitely do it!"
After saying this, the girl with red hair and a slightly weird personality came to the village entrance as quickly as possible and embarked on the journey to Land of Waves with Allen.
Watching the two people walking away, Kimimaro finally couldn't help but ask, "Master Orochimaru, is it really okay to cooperate with that person? I always feel that he is using us."
"Hahahaha! No problem! Because I know he is using me, but I am not using him. Especially this power called mind can make me take a big step forward in the direction of eternal life." Orochimaru explained with a laugh.
For him, it doesn't matter whether he is being used or not. What matters is getting what he wants. Otherwise, he would not have chosen to cooperate with someone like Danzō back then.
"Is that power called reading really that magical? Can it even cure my disease?" Kimimaro said with strong doubt in his tone.
"Of course! Just like Allen-kun said, Nian is a power full of Infinity possibilities, and it is also a reflection of a person's true heart. The more you desire something, the more abilities you can get from Nian. So I believe that it will definitely cure you. Disease. Let's go to the laboratory and continue to modify your body. You must know that it is not easy to accommodate Chakra and Nian at the same time. Even Karin, who has the blood of the Uzumaki Clan, took a lot of effort."
Orochimaru said as he took Kimimaro and disappeared deep into Sound Ninja's underground tunnels extending in all directions.
With the complete success of the experiment on Karin, he could not wait to verify it again on the second person.
And Kimimaro, who has a strong blood inheritance and personal strength, but has been troubled by illness, is naturally the best test subject.
After all, the blood disease has exceeded the scope of treatment by Medical Ninjutsu. Instead of waiting for death to come slowly, it is better to try another different power system.
