Aoba strolled through the dark corridor. Now that he had come here again, he felt that there was a slight change compared to yesterday.

This place had become even colder. He did not know if it was because there was no candlelight.

Aoba controlled the chakra in his body and directed it toward his eyes, allowing him to see the path in front of him even though it was extremely dark.

This was a circular corridor and was sinking bit by bit. It could be seen that this was a structure that kept going downwards.

"Now, under my feet should be the Root Base. If I guess correctly, there must be an entrance to the Root Base here."

Aoba thought silently in his heart. The corridor was extremely quiet now. There was no sound at all. It was precisely because of this reason that he did not dare to make any noise, afraid that he would be discovered by the people here.

In the memory of the people, he had read. There was no information on this part.

Aoba carefully walked around the circular path downwards. After walking for about ten minutes, he arrived at the end of the corridor.

'There should be a stone door here.'

Aoba had come here before.

'After that were stairs.'

At this time, Aoba stood at the stone door. He did not immediately open the door but carefully listened to the movements around him.

'There is no sound.'

Then, Aoba slowly pushed open the stone door.

A downward path was presented in front of him. He then started going down step by step. When his feet landed at the end of the downward path. Aoba immediately realized that this was the location of the interlayer between the basement and the ground.

It was also the place where Aoba and the others had read corpse memories. It was just one of the secret doors here. As for what exactly was inside of the other secret doors, he didn't know.

Then, Aoba walked in step by step.

A while later.

He came to the side of the secret door from last time. He stood at the door and hesitated a little, but he still pushed the door open.

Rumble...

Along with a series of sounds, the stone door was opened. The room inside was as dark as before. However, Aoba could see the corpses of Kumogakure ninjas on the iron shelves.

"Huh?"

Aoba suddenly felt a little surprised.

"Why are these corpses not taken away?"

A question mark appeared in Aoba's head. However, he was not polite. There was no one here, so he could completely read the memories of these corpses.

Then, Aoba stretched out his right hand and touched the heads of these corpses in turn.

"Ding Dong! Memory Reading Succesful! Obtained..."

The clear electronic prompts kept ringing in Aoba's mind. Along with these sounds, the system gives one ninjutsu after another.

The level of these ninjutsus was not high. Moreover, there were many repetitions. It was equivalent to deepening Aoba's understanding of this ninjutsu.

At the same time, a series of memories emerged in Aoba's mind. These were all the memories of Kumogakure ninja when they were still alive. But it has no value; after all, the memories of these Kumogakure Ninjas could not compare to Kumogakure Advisor.

After Aoba finished reading the memories of these Kumogakure ninjas, he walked toward the room door.

He did not go out. Instead, he stopped behind the stone door and raised his right hand. His palm pressed against the wall next to the stone door.

Hum!

Aoba controlled his chakra to move to the wall next to the stone door. In an instant, a black circle was created. It was Aoba's Flying Thunder God Formula.

After this Flying Thunder God Formula appeared, it merged with the entire dark environment. If one didn't look carefully, they wouldn't be able to find it.

When Aoba was doing the mission. He had thought of leaving behind a Flying Thunder God Formula here. But at that time, Kaze, who was not far away from him, had been staring at him. This made it so that he had no chance to leave the Flying Thunder God Formula.

If he acts rashly, there would be a danger of being discovered. Moreover. It was proven through facts. This Kaze could really do anything!

If the Flying Thunder God Formula were discovered, then things would become much more troublesome, which would far exceed the convenience brought by this Flying Thunder God Formula.

After Aoba left this Flying Thunder God Formula, it was equivalent to leaving a coordinate here. Then he walked out of the room and slowly closed the stone door, then looked deeper.

It was still dark ahead and as if there was no end to it. Aoba's face turned solemn because things had already exceeded his expectations. But it was still much smoother than he had imagined.

Because there was no Flying Thunder God Formula here, he had to enter directly from the front.

That was why he chose to use his identity and appearance. Even if he was discovered, he could still use this as a reason to send the book to Danzo and force this matter over.

Of course, he could also disguise his identity. When he was discovered, he could use Hiraishin no Jutsu(Flying Thunder God Technique) to escape. However, that would expose the fact that he would use Hiraishin no Jutsu(Flying Thunder God Technique).

Aoba felt that the only place where he exposed his space-time ninjutsu was when he was fighting with Orochimaru. Apart from that, even when he transformed into Gasshi and entered the Root Base to attack Hari. What he presented was only a synchronous reverse summoning technique.

That was why Aoba felt that unless he had no other choice, he should try his best not to expose the fact that someone could use Hiraishin no Jutsu(Flying Thunder God Technique).

Especially when that person was discovered, he would be crowned with the name of an intruder.

When he used Hiraishin no Jutsu(Flying Thunder God Technique) in the future. Everyone would know that he was the one who did it. This was a tail that he did not want to leave behind.

But it was different now. Aoba had already reached the furthest distance he could reach with his real identity.

If he continued to move forward. Then even if the book were given to Danzo, it would not be possible to round it.

He had to change his identity.

Aoba immediately used Shikigami no Mai(Dance of the Shikigami). He controlled his body to turn into paper and then used Kami no Shisha no Jutsu(Paper Person of God Technique) to change his appearance.

Aoba directly turned into Kaze and then took out the cloak he had prepared from the ninja pouch. He then put the hood on his head.

There was a reason why Aoba had become Kaze.

After what happened yesterday, he felt that Kaze was not a good person. If there was a chance, he could make Kaze suffer a few times. There was no burden in his heart at all.

The other was that if he wanted to get out of this place, he absolutely could not use an outsider identity. He shouldn't carry this pot. This was also the reason why Aoba chose to transform into Kaze.

After the transformation was completed. Aoba silently walked toward the end of the corridor.

A few minutes later.

Another stone door appeared. The style of this stone door was exactly the same as the previous one. There was no need to think about it at all. The layout inside was probably the same.

Thinking of this, Aoba approached the stone door and listened to the movements inside.

He did not hear any sound. It was almost certain that there was no one inside.

Aoba no longer hesitated and immediately pushed open the stone door.

Rumble...

There was another heavy sound. The stone door was pushed open and inside the room were iron shelves. The style was the same as the one in the previous room. Moreover, not only were the iron shelves the same. Even the iron shelves were filled with corpses.

"This is..."

Aoba's pupils shrank. He walked toward the nearest iron shelves, his eyes focused on the corpse on it.

This corpse looked like it had just died. There was no sign of decay at all. Obviously, this corpse had undergone embalming. Moreover, the internal organs of the corpse had already been hollowed out, and only the head was intact.

"What kind of place is this?"

The doubt in Aoba's heart became deeper. He immediately raised his right hand and touched this person's head.

"Ding Dong! Memory Reading Succesful! Obtained: Katon: Gōryūka no Jutsu(Fire Release: Great Dragon Fire Technique)!"

An electronic prompt immediately sounded in Aoba's mind. He once again obtained ninjutsu.

Because he obtains ninjutsu. He knew that the corpse lying on it was at least a ninja when it was alive. Almost at the same time, a stream of memories poured into Aoba's brain.

"Let's get the memories of all the corpses here first."

Aoba did not immediately stop to check the memories. Instead, he chose to get the memories of every corpse in the room.

Along with the crisp electronic prompt. A series of memories surged into Aoba's mind.

After getting the memories of every corpse in this room, Aoba walked toward the entrance. He raised his right hand and pressed it against the wall beside the stone door.

Hum!

After Aoba's palm came into contact with the wall, it released a faint fluctuation, leaving behind an indistinct Flying Thunder God Formula on the wall. Only then did Aoba relax. He leaned against the wall and hid in a dark corner.

This way, even if someone were to enter this room. They still wouldn't discover his figure at the first possible moment, giving him the opportunity to use Hiraishin no Jutsu(Flying Thunder God Technique) to leave before he was discovered.

People who came in would only think that there was no one here instead of seeing Aoba use space-time ninjutsu to disappear.

Suddenly, Aoba began to check the memories he had just obtained.

Gradually.

Time passes by.

Aoba did not move for more than half an hour.

"Phew..."

Aoba heaved a long sigh of relief, and a complicated look flashed in his eyes. He had already checked the memories of these corpses. These corpses were not Konohagakure people but Amegakure people.

According to the memory of the corpse. These corpses had been lying here for a few years, even earlier than when Aoba came to the ninja world.

It was during the Second Ninja World War when Amegakure attacked Konohagakure, but they were killed instead.

According to their memories, all these ninjas received orders from their leader, Hanzo. They formed a vanguard suicide squad and directly broke into the territory of Country of Fire and directly attacked Konohagakure.

It was precisely because this ninja squad killed many of Konohagakure's ninjas, Hiruzen decided to send his student to go to the Country of Rain to fight with the ninjas in Amegakure.

"How could these corpses be left here?"

Aoba was not very clear about the function of these rooms. They looked like a morgue, but these corpses were specially processed. There was no sign of decay at all, just like a specimen used as displayed here.

In the process of obtaining their memories, Aoba checked their brains through medical ninjutsu.

Their brains were indeed not dug out. But in order to prevent decay, a lot of additives have been poured into it, and it has formed a solid state.

If Aoba did not have the Mind Reading System, it would be impossible to read the memories of these corpses. These corpses were already in a state of being unable to read their memories.

"Could it really be a collection?"

Aoba faintly felt that the corpses stored in this secret room might be the ninjas that died when they fought with Konohagakure.

Before the corpses of these ninjas could be taken away by the people of the corresponding village, they were brought back by Konohagakure ninjas.

Strictly speaking...

These could be considered spoils of war.

'Wait!'

Aoba suddenly looked at the corpses not far in front of him, and a very strange thought appeared in his mind.

'The internal organs of these bodies have been hollowed out and embalmed, and there is no trace of haste in the way of processing. It looks like a finished work of art...'

Aoba muttered in his mind. He definitely did not have the mouth to say these words loudly. After all, he was still in the room, and the surroundings were very quiet. As long as he made even the slightest movement, it was possible that the people here would find out.

'Orochimaru!'

A name popped up in Aoba's mind.

At this time, Orochimaru was still doing all kinds of research on the human body. What he was pursuing was to master all kinds of ninjutsu, as well as the method of immortality.

The internal organs of these ninja corpses were all gone. It just happened to be in line with the research on Impure World Reincarnation Ninjutsu and also the collection of personal information.

Of course, these little ninjas were not worthy of wasting living sacrifices for reincarnation. Even when they were still alive, they didn't even have the qualifications to be a sacrifice.

"Let's go take a look at the other rooms."

Aoba guessed the function of these rooms. It might be the place where Danzo and Orochimaru worked together to study the human body.

'The object of research was the intruders from the other village.'

'Eh... '

When Aoba thought of this, he took back what he had just said. It was such a long corridor, and it was unknown how many rooms there were.

'Could it be... '

'Were there really only people from the other village?'

At this moment, a lot of bold thoughts suddenly came to Aoba's mind.

'It seemed... '

'It was possible to solve the puzzle I encountered when watching Naruto.'

Thinking of this, He walked deeper into the corridor.

A few minutes later.

Aoba came to another stone door. He raised his hand and pushed open the stone door. Along with the rumbling sounds coming from the stone door, the dark room had already appeared in front of Aoba.

Then.

Aoba walked in.

The structure of this room was exactly the same as the previous two rooms. Even the layout was the same, with iron frames and platforms.

Only...

There were no corpses in this room. It appears to be not filled yet. However, Aoba did not leave just like that.

Just like before, he raised his right hand and slapped it on the wall next to the stone door, once again imprinting a Flying Thunder God Formula on it.

After this Flying Thunder God Formula appeared. Aoba walked out. Right now, his idea was very simple. He wanted to leave a Flying Thunder God Formula in every room.

This way, As long as he thought about it in the future. He could come to this room at any time.

It may even be possible to store some shadow clones here for training during some extraordinary times, which was not necessarily impossible.

The most dangerous place was sometimes the safest place.

Then Aoba continued to walk deeper into the corridor. He opened one stone door after another. The rooms behind the two rooms only had iron shelves and no corpses.

This scene made Aoba doubt his own speculation.

"Could it be that this is not the place where the corpses are stored?"

"Everything that happened just now was just a coincidence?"

"Coincidentally, there is no place for these corpses to be placed?"

Aoba was immediately puzzled. There was nothing in the stone room, which made him start to doubt his own speculation.

After walking for a few more minutes. A stone door appeared in front of Aoba once again. Faced with such a scene, Aoba was already very familiar with it now.

During this period of time, he had been opening the stone doors of these rooms. It could be said that he was very used to how to open these stone doors.

Rumble...

Accompanied by the sound of the stone doors rubbing against the ground. Aoba pushed open the door of this room.

All of a sudden, A pungent smell came from inside the room.

This smell seemed to have been sealed for a long time, with a rotten smell. It seemed that this stone door had not been opened for a long time.

"There's something here!"

Just by smelling the scent, Aoba immediately realized that there was definitely something inside. He wasn't sure if it was a corpse or not, but it was definitely different from the previous empty rooms.

After that, Aoba walked into the room. What entered his eyes were the iron shelves. These iron shelves were embedded into the ground and could not be moved or moved at all.

Aoba quickly looked at the top of the iron shelves, and his eyes flashed with expectation. The things on the iron shelves would verify his guess to a certain extent.

"As expected!"

Aoba widened his eyes. In his sight, he could clearly see the corpses on the iron shelves. These corpses looked like the corpses from the other room. They were all processed.

Only...

These corpses were already beginning to give off a strange smell. It was obvious that it had been stored for too long. Even the embalming could not preserve it.

After all, the person who had the most advanced technology and developer in the ninja world was Orochimaru. At this time, Orochimaru had not fully developed this technology, so there was no way to make the kind of corpse that could be preserved for hundreds of years.

"These corpses should be from the First Ninja World War!"

Aoba immediately put away his curiosity, raised his right hand, and slapped the heads of these corpses then crisp electronic prompt continuously rang out in Aoba's mind.

Ninjutsu and memories pour into Aoba's mind one after another and take him back to the history of Konoha at the beginning of its establishment...
