"How did the talk with that guy go."
After Uchiha Madara was sealed into an Impure World Reincarnation coffin, Ryun returned to the room of the biological laboratory.
"Heh, he did not give a clear stance, but his body also did not excessively resist anymore. I suppose he listened to what was said," Orochimaru said with a smile.
"Judging from Uchiha Madara's resistance, the Impure World Reincarnation technique would find it very difficult to completely control high-level Six Paths beings like Ōtsutsuki Isshiki and Kaguya," Ryun suddenly remarked with a sigh.
Hearing this, Orochimaru's smile froze, but he did not refute it.
"Implant my body's cells into the White Zetsu. Try to see if we can create two or three powerful individuals to serve as sacrifices for the Impure World Reincarnation. Also, make a copy of the Impure World Reincarnation technique scroll for me. I want to see if there are any areas that can still be improved."
Ryun agreed to let Orochimaru use his body's cells for transplantation. The transplantation subjects were still the White Zetsu, an aberrant species with extremely high adaptability.
Apart from Ryun's direct blood relatives, normal humans basically could not bear his body's cells. Only a special creature like the White Zetsu, which had long been steeped in the Ten-Tails' power, could withstand Ryun's god-level cells.
"Good. I will personally handle this transplantation research now. Kabuto, copy all the information related to the Impure World Reincarnation technique and give it to the Shadow."
"Hai."
Kabuto Yakushi responded and hurried out to copy the materials.
Taking advantage of this time, Ryun opened the Ten-Tails seal on his abdomen and transferred a large number of White Zetsu from within the Ten-Tails to the outside. These were all the elite White Zetsu with powerful physiques.
For example, the Aloe White Zetsu and the Spiral White Zetsu that previously served Black Zetsu.
The Aloe White Zetsu possessed the terrifying ability to reproduce Spore White Zetsu almost infinitely. The Spiral White Zetsu possessed the perfect ability to possess others. Even if it possessed a worthless person, it could instantly grant that person Kage-level peak combat power. These two White Zetsu were both elite White Zetsu.
Ryun not only provided White Zetsu, he also specifically controlled the Ten-Tails to create ten human-sized Ten-Tails split bodies. If the White Zetsu ultimately could not bear his body's cells, Ryun would also allow Orochimaru to use these Ten-Tails split bodies.
Ryun was not worried about creating monsters. As long as the monsters could still become reincarnation sacrifices, it was fine. What he had been considering was how to better control Six Paths-level Impure World Reincarnations.
Not long after, Ryun took all the information scrolls regarding the 'Impure World Reincarnation technique' from Kabuto Yakushi.
"I will go study this forbidden technique first to see if there is any room left for further improvement and enhancement." Ryun intended to leave directly.
"I feel it is already very difficult to improve further. But if it is you, perhaps you really can do it," Orochimaru said with a helpless smile.
"I will do my best."
After saying this, Ryun's body suddenly returned to the study in his home.
Sensing little Junlin mischievously causing trouble at home, Ryun chuckled softly. Then, he directly unrolled the forbidden technique scroll and began studying it seriously.
Time flew by, and another month passed.
During this period, the Village of Heaven had deployed the Celestial Eye monitoring and early warning system. They had also constructed a large astronomical observation base on the moon.
Through precise astronomical telescope observations, although the Hyūga Clan had not yet spotted traces of those enemies, they did discover several special life-bearing planets with liquid oceans and oasis continents.
However, these life-bearing planets were all relatively distant from the Ninja World. Without mastering spatial abilities, even Six Paths-level experts would likely find it difficult to reach those places.
The Village of Heaven quietly marked those places and created a simple star map. Perhaps they could send some idle Six Paths-level members from the village to explore those places in the future.
Ryun spent this month conducting detailed research on the Impure World Reincarnation technique. Unfortunately, he did not succeed in improving this super S-rank forbidden technique as he wished.
Just as Orochimaru had said, this forbidden technique was already quite complete. There was almost no room left for improvement. It was already remarkable enough for a super S-rank forbidden technique to be able to control some weaker Six Paths-level experts.
Finding the path of improving the forbidden technique impassable, Ryun planned to try a different approach. An idea formed in his mind to combine the Impure World Reincarnation technique with sealing techniques.
While Ryun was buried in his research of the forbidden technique, the entire Village of Heaven suddenly shook.
Ryun only needed to sense slightly to find that the problem was on Orochimaru's side. The next moment, his figure immediately appeared within the biological research base.
"Roar."
What met his eyes was a ferocious and terrifying humanoid monster. It had just broken free from the restraints of chains and seals. With just a casual punch on the ground, it created a huge crater. At this moment, it was roaring wildly and aggressively at Orochimaru.
Ryun raised his hand and shot out several Adamantine Sealing Chains. The humanoid monster that was going on a rampage trying to cause destruction was immediately tied up like a rice dumpling.
Seeing this, Orochimaru could not help but breathe a sigh of relief.
"What is the matter with this monster." Ryun instinctively frowned and asked.
"I transplanted your body's cells into it. As a result, this monster underwent some unknown mutation and started to rampage uncontrollably," Orochimaru hurriedly explained.
Hearing this, Ryun was stunned for a moment. His gaze involuntarily focused on the humanoid monster.
This was a Ten-Tails split body. After being transplanted with Ryun's cells, its overall power was greatly enhanced. Moreover, its ugly beast-like face was quietly transforming to resemble Ryun's appearance.
The cell transplantation project had Ryun's permission, so he had no reason to blame Orochimaru now. Instead, he asked about the situation with the White Zetsu.
"The powerful White Zetsu you left behind have all died except for one," Orochimaru said, pointing to a special White Zetsu imprisoned in an iron cage in the distance.
"That guy perfectly meets our requirements. It is both the only surviving specimen and a relatively perfect sacrifice for the Impure World Reincarnation."
Following Orochimaru's direction, Ryun saw the special White Zetsu sealed inside the iron cage. The moment its gaze met Ryun's, this White Zetsu suddenly tilted its head. Its originally white face instantly transformed into Ryun's appearance.
Seeing this scene, Ryun could not help but frown.
Whether it was this White Zetsu or the Ten-Tails split body he had personally subdued, these monsters transplanted with his body's cells did not make Ryun feel the slightest closeness. Instead, they evoked a certain physiological disgust in him.
If it weren't for the need to create suitable sacrifices for the Impure World Reincarnation, Ryun would definitely not tolerate their existence.
"I think we can start sacrificing them now. Delaying might lead to unforeseen changes," Orochimaru said seriously, giving his suggestion.
"Alright. Go prepare the Impure World Reincarnation ritual," Ryun nodded heavily.
