After the fourth generation of raid shadow cells was re-opened, a new breakthrough was made in just two days, and Danzang should be very happy about this.

Natsuki was just a routine. She walked around the laboratory and confirmed that everything was running as usual, then came to Orochimaru's house.

"It turned out that the illusion was arranged." The moment Xia Shu walked into the secret passage leading to the underground cave, he confirmed what was hindering his heart network's perception, and this obstacle was also the reason why he corrected his "wrong".

"There are only a few types of perceptual ninjutsu. Apart from the simple but ordinary way that cannot be hindered by visual investigation, it is not difficult to target specifically." Orochimaru laughed.

"Yeah." Natsuki nodded, then turned his attention to the deep and dark authenticity, "What you said will interest me is below?"

"It's very convenient and secretive, isn't it?"

"Convenience is convenience, but to be secretive, it's actually a little bit worse." Xia Shu shook his head and said.

"It's enough now." Orochimaru's mouth slightly slightly, and his tone was a little ridiculous.

Compared with the narrow and cramped passage, the underground space is very spacious and roughly divided into two parts. On one side, it is mainly daily utensils, such as tables and chairs, paper, pens and ink, etc., and on the other side, it is mainly research tools, which are found in the root laboratory, and can be seen here.

The person who attracted his attention the most was the man tied to the laboratory bench. His appearance was a little strange, but it was also certain that he had seen him as a Konoha ninja!

"His name is Shinnosuke. He was injured during the third Ninja War. Sanikong's toxin eroded into his internal organs. Although it detoxified, it also caused his organs to gradually become exhausted." Orochimaru held his arms and looked at Natsuki who was walking towards the test bench, and said in a casual tone: "According to the rate of exhaustion at that time, his name has now been engraved on the spiritual monument, but no one should remember him, because his companion died in battle and was still an orphan himself."

"So even if it disappears, no one will pay attention?" Natsuki stood in front of the laboratory bench and sighed.

"Nashi Shujun thinks this is not good?" Orochimaru looked at Nashi Shu's back with interest.

"Well, but..." Xia Shu nodded and shook her head, saying uncertainly: "Organ failure is a serious disease, and the mortality rate of multiple organs is higher, so it should be a good thing to be able to exert the residual value, right?"

"So what you care about is his identity?" Orochimaru raised his eyebrows slightly, and then said to himself: "Actually they are the same. All human beings are equal, and they will die if they are killed. Only by transcending the boundary between life and death can one truly higher level!"

"What are you pursuing immortality?" Xia Shu opened her mouth wide and said in surprise.

"Once my ideal was to learn all ninjutsu. In this regard, I did have extraordinary talents. Even if I have a level A ninjutsu, I can master it within a week." Orochimaru's eyes flashed with a look of memories, and he slowly said: "But life has only been for decades, extremely short, just like a flower that will wither in the past. If there is no long life, how can I exhaust the truth and explore the unknown? On the battlefield, I have seen too many people die, strangers, familiar people, and even those around me, so many that I have forgotten many faces... You may not know yet, Natsuki, your teacher Tsunade's younger brother, Yoshiki, was once my subordinate, the vibrant but reckless boy stepped into a trap set by the enemy in front of me in a battle."

When he said this, he paused slightly, and then faced the eyes of Xia Shu who had turned around, his eyes flashed with a scorching light and said, "So, I want to develop a true immortal art, and even if I give up everything, I must achieve my goal!"

The underground space fell into silence, and after a long time, Xia Shu opened her mouth to break the silence.

"It should be an honor to see such a technique, right?" Natsuki looked at Orochimaru with a calm face.

"Of course!" Orochimaru raised his chin slightly. He was a proud person, so he naturally did not hesitate when facing this problem.

"So, please allow me to obtain such qualifications, Lord Orochimaru." Natsuki said in an expectant tone.

"As you wish." Orochimaru smiled and walked towards the test bench, "Now, come and help me, this experimental subject will not be able to hold on. I still have a small question to find the answer from him."

"Yes." Xia Shu put on the experimental clothes and began to act as an assistant to help.

The unknown Konoha Ninja on the test bench will eventually usher in the fate that he should have.

After finishing the experiment, Natsuki was responsible for cleaning the test bench, while Orochimaru went to the other side of the underground space to find a scroll prepared in advance.

"This is the basic idea of ​​this research. Take it back and take a closer look. If you have any ideas, you can tell me next time." Orochimaru threw the scroll to Natsuki, and said in a casual tone.

"Next time, when?" Xia Shu asked after taking the scroll, just a glance.

In fact, he was not calm at this moment, because next he only needed to determine the idea of ​​the scroll's idea of ​​the corpse-free reincarnation technique, so he could mention the spiritual transformation technique to Orochimaru, and then obtain this S-level soul ninjutsu.

However, judging from the current progress of Orochimaru's research, it seems that it has not yet penetrated into the soul. The exploration of the experimental subject just now is still limited to the physical level.

So, perhaps he should have made some guidance to make Orochimaru's perspective separate from the physical level and start studying the soul.

The information on the failure of the Beiliuhu experiment seems to be able to prove this idea. After all, Beiliuhu's attempts are all on the physical level.

Of course, these must be discussed before confirming the content of the scroll.

"I will look for you next time." Orochimaru said, "Now I want to start summarizing the previous experimental data, find details that will be helpful to the next research, and then selecting new experimental subjects, which will take a lot of time."

"Yes." Xia Shu put away the scroll and said, "Then I'll say goodbye."

"Just leave by yourself." After Orochimaru came to the table, he was at the desk and waved indifferently when he heard this.

Xia Shu nodded slightly, then turned around and left.

He returned home all the way, closed the doors and windows, sat cross-legged at the table, opened the scroll Orochimaru gave him, and began to read it carefully one by one.

The scroll has not much content, and only half of the text is all. In addition to the first half of the content, which echoes up and down, forming a system, the following is purely some sudden and whimsical records, which itself has little value.

And most importantly, the content of the scroll was too far off from what he expected.
