"Yin Escape - The Art of Invisibility", after a short moment of stunned, the figure of the masked man disappeared into the water. At the same time, subtle ripples moved towards the landing position.

"I feel it...... It is the power of the intercolumnar cells. Sure enough, my sister really did research on intercolumnar cells. "After entering the city, the masked man obtained a lot of information from passers-by. Then, knowing everything, he slowly walked towards the cuckolded mountain.

Because he knew the characteristics of the world's techniques very well, under the gaze of the writing wheel, he easily and correctly avoided many defenses of trigger-type vigilance. "This type of alert? Looks like this place has been invaded! ”

In fact, this guess is quite different. As early as a few years ago, the second-generation Mizukage Ghost Lantern Phantom Moon of the Fog Hidden Ninja Village personally infiltrated the Hidden Country. At that time, after cracking and entering the enchantment, he relied on his excellent Yin Escape Technique to enter and exit the realm of no one here. If it wasn't for Uchiha Beimiao who was on duty at the time and saw through his existence, otherwise the country's intelligence is estimated to have been leaked. In this regard, after that, countless trigger-type alerts have been set up on the island of the Hidden Country. Of course, because it has a strong Uchiha style. So these warnings are naturally of little use to the masked man.

What the masked man wants is in the research institute of the Hidden Country. Among them, the location on which it was established was in the interior of an extinct volcano. That's right! It is the one where the world and the chestnut were built. Among them, with the development of the past ten years, the scale of this scientific research institute has expanded to more than ten times the size of the previous one. If the world returns one day, then she probably won't recognize this place. After all, too much has changed here!

The original research institute opened several caves in the interior of the extinct volcano. Compared to now, the extent to which the world and Kurino exploited this mountain at that time was actually more than one thousandth. Then, as time passed, the scale of the research institute increased, and the degree of mountain development also increased. By now, they have dug a huge sinkhole in the crater of this extinct volcano. The location of the scientific research institute has covered the top and bottom of the pit wall.

As for the vacant lot inside the sinkhole? At this time, it was occupied by a giant tree more than two hundred meters high.

The data of 200 meters, in fact, most people are not very sensitive. After all, the circle of the playground track in the school is 400 meters long. However, two hundred meters long and two hundred meters high are two different concepts. Imagine when the height of a human being is only as long as one of your fingers. Then, when you stand in the middle of the city, you will realize how huge you are for the city. Compared to the giant tree with a height of 200 meters, less than two meters is how small you are to this giant tree.

Every newcomer who comes to the research institute for the first time will be amazed by the enormity of this giant tree after seeing it. However, for the masked man, it's all OK! After all, his Susanon is almost the same size as his complete body. Therefore, just after a stunned effort, the masked man came back to his senses from the thought of sighing life. Then, he began to scrutinize the giant tree in front of him.

Because of the special vision of the writing wheel, the masked man at this moment can clearly see the countless chakras in the giant tree leading to unknown places through some pipes. Although the writing wheel eye does not have any perspective function, he can vaguely guess where these chakras lead.

Wind and thunder, water, fire and earth, the five nature of chakra changes. At this time, this island nation of 50,000 people actually has all the changing chakra technology. And the source of the required chakra is the giant tree in front of him. Thinking of this, a smile appeared on the face under the mask of the masked man.

"This country, is this her ninja?" With that, he shook his head and left the place, heading towards the depths of the research institute.

The purpose of the masked man is only to obtain all the scientific information of the intercolumnar cells. For this reason, for the sake of saving effort and the world, he did not intend to make a big fuss and seize it by force.

"It's here! The data room ......", and after a little time, the masked man successfully came to the door of the data room.

"Sealing? I haven't seen a technique before, it seems to be ...... People here aren't just eating her old book! Looking at the wall in front of him covered with sealing, the masked man smiled. And then......

"Iyenagi - Turn back time!" In an instant, the three-hooked jade writing wheel eye of the masked man's right eye changed to the pupil pattern of the straight eye. After that, under the powerful pupil force, the masked man kept deleting the "now" of the sealing technique. Finally, at some point in the past when he had opened the seal, he had turned back his time to this point in time.

"......", in the silent footsteps, the masked man strolls through this huge library.

"The Original Catalogue of Ninja Forbidden Books" ...... Eleven bookshelves......

"Chakra Tree Research Record...... Two bookshelves......

"Research on Chakra Automation Technology...... Six bookshelves......

"Research on the Cells of the Thousand Hands Intercolumns" ...... Three bookshelves......

"That's it!" As if seeing the information he wanted, the masked man walked towards the bookshelf with "Cell Research between the Thousand Hands Column". Then, in the column of transplanted cells, the masked man picked up the first box.

"Rustling ......", after that, there was a sound of paper flipping through the silent data room. At the same time, about an hour later, the Masked Man was unfortunate enough to encounter someone entering the data room.

"Dash...... Click......", after that, the rustling sound of flipping books disappeared in an instant. At the same time, only the footsteps of one man remained in the air.

Opening the writing wheel eye to think is a behavioral habit of Uchiha Kurino.

Life is short, but science never ends. In this regard, Uchiha Kurino is conducting more research in order to be able to do more research in a limited time. As a result, she gradually got into the habit she has now. However, what she didn't expect was this. Today's habit has made her see something different - a person who is covered in chakra.

In an instant, Uchiha Kurino was a little flustered. However, the maturity that came from her heart calmed her down in an instant.

"Has it been discovered?" Although her movements were very well disguised, under the dynamic vision of the masked man's writing wheels, this behavior could be said to be blatantly told to him...... I see you!

So, after the next second, the masked man unlocked the invisibility technique and revealed his true body in front of Kurino.

"Are you...... Spot!!! "Although the color of the chakra has changed due to the transplantation of intercolumnar cells, the color of the pupil force of the eye cannot be easily changed. Therefore, just by seeing the masked man for the first time, Kurino recognized his true identity from the masked man's pupil power color.

"You're not dead!!"

"No...... Madara Uchiha is indeed dead, and now stands in front of you...... It's just a ghost named Uchiha......" the masked man said in a calm tone.

"That's amazing!" Facing a person who should have died, Kurino showed a mocking smile at this time. "Fake your death? You've managed to kill your own sister! ”

“……”

“…… I should have stopped her ...... a long time ago," Kurino Uchiha muttered as he closed his eyes in pain. After that, she opened her eyes and looked at the masked man.

"What are you doing here?" Wiping away her tears, she said coldly to the masked man.

"I'm going to ...... All research data on intercolumnar cell transplantation. The masked man held out his right hand to her, saying his purpose.

"Huh! Why do you want her stuff! Do you think you have any qualifications!? ”

“…… I have nothing left...... But...... You still have the ...... of this country", the masked man said in an indifferent tone, "You don't give it to me...... I can take ...... myself."

"This guy ...... Anything can be done! Regarding the masked man's statement, Kurino interpreted this meaning in his heart. So, she said slowly: "Compared to an indifferent person like you, I do have too many weaknesses. Aren't you going to study the data? Take it! ”

As he spoke, Kurino had already thrown a scroll at the masked man. Then, she continued, "This scroll is stored in the ...... is a copy of all the materials in this room. Usually, I don't come here very often, so I have a copy warehouse with me. ”

"Really?" The masked man said lightly. At this moment, he did not immediately disassemble this scroll, but said a word to Kurino.

"This place...... You shouldn't want me to come a second time......"

"I understand the severity, and by the way, I don't want to be associated with someone like you."

"That's good ......," he said, and the masked man re-entered his invisibility. The next moment, he left here generously under the eyes of Li Nai's writing wheel.

“…… Looks like it's time to strengthen the barrier...... No! Forget it, with his strength, the enchantment-type defense is estimated to be ineffective. It seems that the study of chakra weapons is on the agenda......"

"The country ...... It cannot be destroyed in anyone's hands...... It is...... Her heart ...... mind"

……

"Reverse Psychics!" After making sure that he really got what he wanted, the masked man formed a psychic spell in the reverse order of sealing. The next moment, accompanied by a burst of white mist, his figure appeared in the underground base near the Kamino Bridge between the two countries of fire and earth.

"Click!" The masked man hangs his scythe on the wall. After that, there is the Vortex Mask, a black trench coat with a hood. In addition to these items, the original wall was covered with Uchiha fans, other masks, and a matching black trench coat.

"Dash...... ......", then, after unloading his belongings, Madara slowly walked to a stone chair. Then, he sat there quietly with his eyes closed.

There is no superfluous movement, and there is no superfluous sound. At this moment, in this underground cavern, everything is so silent, everything is so boring......
