There was no situation next time. The group of people from the Ronchi River did not rest. After rushing all night, they returned to Konoha Village the next day.

Natsuki had some speculations about what happened at that time and the existence of not showing up, but no matter what the guess was, it was no longer important now that things had passed.

Root base.

Natsuki came out of Danzo's office, went around the laboratory deep in the base, and then left the base and came to Orochimaru's house.

"Oh? The mission of Danzo's secret dispatch was completed?" Orochimaru asked with a smile when she saw the visitor.

"Have you heard it too?" Natsuki followed Orochimaru and came to the house.

"Haha, it must be interesting to attract that old guy." Orochimaru smiled hoarsely, "Come on, I just happen to need your help."

"I'm sorry, I can't reveal any news." Xia Shu reached out and pinched her tongue, revealing the seal of the tongue's roots, and said apologetically with a hint of bitterness.

"In terms of the research on sealing techniques, that old guy is also an expert." Orochimaru looked at the curse seal on Natsuki's tongue, squinted his eyes and said in a slight inspiration: "But this kind of curse seal is not impossible to crack."

After hearing this, Natsuki looked at Orochimaru, his eyes flashed a few times, and finally shook his head and said, "Thank you, Lord Orochimaru for your kindness, but although my life is insignificant, it also needs to be cherished for me."

"Haha, can I still joke about your life?" Orochimaru said with a smile.

Natsuki heard that the other party was not dissatisfied, so he just shook his head slightly and said, "If you are too careless as a ninja, you will definitely not live long."

When he arrived at the underground laboratory, he began to process the materials on the laboratory bench as Orochimaru ordered, and he was busy until late at night.

"The problem at the physical level is now solved, and it is time to overcome the problem at the soul level." Orochimaru threw away his gloves and picked up a piece of paper and pen to record the data.

"The problem at the soul level is difficult." Natsuki came to Orochimaru and looked at the experimental subject with steady breathing on the experimental bench and said: "Have you ever studied this before?"

"The soul is also a strange field to me. But, correct it." Orochimaru kept saying to Natsuki: "Although the problems at the physical level have been overcome at present, after studying the issues at the soul level, the former predicts that corresponding situations will occur again. After all, the body and the soul are not separated after all."

"Add to teach." Natsuki subconsciously appeared in his mind that Orochimaru turned into a white-phosphorus Orochi, but then he realized that transforming his body into that appearance seemed to be related to the Yaqi technique.

Of course, this is just his guess. What is the actual situation and may be revealed in the future.

"Back to the point, although I have not conducted research on related souls, there are some information on this aspect in Konoha Village." Orochimaru's pen paused, letting the ink traces naturally dry, and looked at Natsuki with interest and said, "Naki Shujun, do you know what there are?"

"Is this a test of whether I have the opportunity to participate in the next research?" Xia Shu asked with a raised eyebrows.

"That's right." Orochimaru laughed, "But if I remove you, I don't know where to find a capable assistant like you."

"You've been too rewarded." Natsuki said modestly, "As for the research on the soul that Konoha Village has, I think it should be from the hands of the second generation master, right?"

"The second generation of Memorials has indeed left a lot of precious wealth." Orochimaru sighed sincerely, "But if you want to talk about the most research on the soul, the Kato clan who only has one person left."

"Kato clan?" Natsuki pinched her chin and thought for a moment, "Is it silent?"

"It's her, it's a pity that she did not inherit the unique talents of the Kato clan." Orochimaru said with regret in his tone, "What's even more pity is that the Kato clan only passed on one soul ninjutsu that was listed as S-level, and there is no research data related to the soul."

"It's really stupid to be complacent." Natsuki sighed when he heard this, "But for the ninja tribe, this also ensures that ninja skills will not be leaked."

"There are many ways to ensure that ninjutsu is not leaked. The Hyuga clan is very good at rolling his eyes." Orochimaru shook his head and no longer continued to get involved in this issue. "In addition to the spiritualization technique, there is also a soul-related forbidden technique in Konoha Village, which was developed by the second generation Me. According to the records, the second generation Melody once asked the Kato clan for spiritualization technique, but because it did not have the talent of the Kato clan's soul out-of-body talent, it did not succeed. However, although the learning failed, the second generation Melody still gained a lot. Later, he was inspired by the spiritualization technique and developed another soul-related forbidden technique, namely the art of reincarnation in the impurity land."

"The Art of Reincarnation in the Immortal Land?" Xia Shu seemed to search through his mind, and finally shook his head and said, "I have never heard of it. What kind of art is that?"

"I want to know too." Orochimaru smiled.

Natsuki glanced at him and thought to himself that Orochimaru had not stole the reincarnation of the filthy land and the art of Yamatsu.

"Haha, don't care about this." Orochimaru put away the dried information and stood up and said, "I'll continue to trouble you with the next research."

"Did I pass the test?" Xia Shu asked intentionally.

"Haha, let's go up." Orochimaru shook his head in a funny way and opened the gate of the passage leading to the ground.

Back in the house on the ground, Orochimaru brewed tea and took a sip. Natsuki talked about the serious matter.

"Lord Danzang sent me to visit because he hoped you could do an experiment for him." Xia Shu stroked the teacup, felt the warm breath of the tea, and raised her eyes and said.

"Oh?" Orochimaru became interested in hearing this, "Tell me."

"Please take a look at this." When Natsuki took it out, Danzo gave him the scroll. "I don't know what's in it, but the signature and number on the side are obviously research notes for the purpose of the second generation."

"This is about the first generation of cells." Orochimaru looked at the cover number and instantly understood. "When I was studying the second generation's purpose notes, I found that some of the missing content in the middle was hidden by Dan Hunting."

"Is this true?" Natsuki looked at the scroll curiously, "The research notes that can be hidden by Lord Danzo should involve very important things."

Orochimaru untied the rope that tied the scroll, read it carefully from front to back, and did not breathe a long breath until the tea completely cooled down, and a hint of joy rose on his pale face.

"So that's how it can inhibit the existence of first-generation cells, it's the Sharingan!"
