Naruto: I start with one door, and I can open it infinitely.

Happy times are fleeting. Lin Chuan and his friends were in their second year at the Ninja Academy, and their first semester started very quickly.

During summer vacation, Naruto and Shikamaru made a new friend, a little boy named Yota. Whenever that boy cried, it would rain.

He declined Naruto and his friends' invitation to go to the forest with them and meet their new friend, Yota, citing his training as the reason.

If he wasn't mistaken, this Yota was a failed resurrection attempt by Orochimaru, abandoned in a forest near Konoha, and his bloodline limit was weather manipulation.

On the surface, it seems like giving up, but who knows if Orochimaru is secretly keeping an eye on this failure? In the anime, the children who play with Yota are basically the direct descendants of Konoha's major clans, so Orochimaru naturally won't do anything to them.

After all, these are all families with secret arts. Once you capture a child from one of these families, it can be very troublesome to get entangled with them.

But he's different. If he gets caught, his parents will be heartbroken, his teacher Maruboshi Kosuke will worry, and Naruto and the others will worry too. No one else will care about his life or death. A genius who hasn't grown up isn't a genius. He can't afford to be reckless.

He didn't plan to leave the village until he had the ability to protect himself. He would wait until he graduated from the Ninja Academy and went on missions outside the village. There would be Jonin leading the teams, so the danger wouldn't be that great. That would be the time to leave the village.

On the first day of school, he skipped class as usual. As the night of the extermination of his clan drew closer, he dared not train alone in the training ground and would train in his backyard after skipping class.

Fortunately, his family lived to the left of the Hokage Rock, while the Uchiha clan lived to the right. Even if the night of the massacre came, it wouldn't affect his side.

……

On a dark and stormy night, the night of the Uchiha clan's massacre finally arrived.

Compared to a major event like the annihilation of a clan, a second-year prodigy at a ninja academy doesn't attract as much attention.

In this gluttonous feast for the Sharingan, the cunning Danzo Shimura, the Uchiha clan, and Orochimaru, who is hiding near Konoha, will likely all be waiting for their chance to make their move.

The three major bosses from the early, mid, and late stages of the story will all participate in this battle for the Sharingan. The Sharingan is a powder keg; whoever touches it dies.

This is also why he doesn't want to get involved with Yota. The night of the massacre is approaching, and Orochimaru has placed Yota nearby. Who knows if Orochimaru will take advantage of the situation?

It's important to know that Orochimaru was in cahoots with Danzo, so it's impossible for him not to know about such a major event. After all, traitors would leak information.

In the backyard of the wooden house, Lin Chuan gazed at the full moon hanging high in the sky. He had a rare day off from training because the village had imposed a curfew, and his cheap old man had also left work early, saying that he was conducting some kind of counter-espionage exercise.

If he wasn't mistaken, Sasuke should have been kept on campus, which is why he knew the night of the massacre had finally arrived.

He decided not to train tonight and decided to relax for the night. He ate dinner early with his parents and then went back to his room to organize his training notes from the past few days.

Around eight or nine o'clock, he came to the rooftop and looked towards the other side of the Hokage Rock, towards the Uchiha clan's territory. That area was shrouded in a dark barrier, and no sounds or screams could be heard, only the low cawing of crows.

"Gah, gah, gah—"

He gently raised his arm, and a rather intelligent raven landed on his hand. This was a raven he had been feeding for more than half a year, and it was also a raven with chakra, making it perfect as a summoning beast.

"Go back to your nest and don't fly around tonight," Lin Chuan gently raised his hand and whispered to the crow before turning around and jumping into the backyard. He went inside, closed the door, washed up, and went to sleep. Tomorrow would be a new day.

……

The next morning, on his way to school, he heard some shocking news: the Uchiha clan had been wiped out, supposedly by Itachi Uchiha.

All the way to school and into the classroom, everyone was talking about it, their eyes subtly fixed on Uchiha Sasuke's seat.

As expected, Sasuke Uchiha didn't come to school today. Instead, he was at Konoha Hospital, where he was hit by Itachi's Tsukuyomi. Although it was a powerful attack, Sasuke will be bedridden for at least half a month.

At this point, Danzo had probably already been relieved of his position as head of Root by Sarutobi Nobunaga. However, these two old men were probably playing the trick of promoting someone in name only but demoting them in reality.

When Nobita Sarutobi needs the Black Gloves again, he will definitely use Danzo again; it's just a matter of time.

Of course, none of this concerned him. He continued his training as usual, refining chakra in the morning and skipping class to train at home in the afternoon.

With the arrival of that old schemer Danzo Shimura, what was bound to happen finally did happen...

……

Wood leaf dark cultivation base, roots...

Danzo returned here feeling very depressed, having just been relieved of his duties as Hokage's assistant and head of Root by Hiruzen Sarutobi.

Later, he was threatened by Itachi with the Mangekyou Sharingan and told not to touch Itachi's younger brother. This was simply outrageous.

It's one thing that Hiruzen Sarutobi, as the Hokage, could overpower him, but what kind of person is Itachi Uchiha that dared to threaten him with village information?

However, he really had no choice. After all, he kept saying he was doing it for the village. If he ignored Itachi's warning and went after Sasuke, Itachi would really betray the village's information.

He had no choice but to swallow this bitter pill. Don't doubt the resolve of a double agent; he's capable of wiping out an entire clan, so betraying village information is just a trivial matter for such a ruthless person.

"How many Sharingan have we collected this time?" Danzo pondered for a moment, finally calming down before asking his subordinate about tonight's haul.

"Lord Danzo, we only obtained seventeen three-tomoe Sharingan. Some of the Uchiha's eyes mysteriously disappeared; they had already been gouged out when we arrived..."

"Who did it?" Danzo raised his hand and gently stroked his chin. He was asking a question he already knew the answer to, because he had informed Orochimaru before taking action, and that guy certainly wouldn't miss such a good opportunity to obtain the Sharingan.

"We found traces of snakes crawling, and the way the Uchiha from the police force died is different from the way Itachi killed them..."

"A third-party force? Could it be Hiruzen's people?" Danzo couldn't help but wonder. What was Hiruzen Sarutobi collecting Sharingan for?

If it wasn't Hiruzen Sarutobi's people, then who would be collecting Sharingan eyes?

Tonight's operation against the Uchiha clan was known only to the Konoha leadership; even the Anbu were unaware of it before the operation. It was only after arriving at the Uchiha clan compound that the Anbu learned their mission was to seal off the Uchiha clan compound.

"Never mind, seventeen three-tomoe Sharingan are enough," Danzo muttered to himself. Besides the three-tomoe Sharingan, he had the most two-tomoe and one-tomoe Sharingan. He could find some people to transplant Sharingan to evolve them to three-tomoe and then dig them out, which would be just enough.

Even if you're not from the Uchiha clan, you can still evolve the Sharingan. He knew that Kakashi had a Sharingan, which wasn't originally a three-tomoe Sharingan, but evolved later.

"How are the children you selected doing?" Danzo continued to ask his subordinates. Evolving the Sharingan is not something just anyone can do. Kakashi is a genius after all, and if he wants to evolve his one-tomoe Sharingan into a three-tomoe Sharingan, he can only take it slowly.

"Lord Danzo, the children from inside and outside the village, as well as the candidates for the orphanage, are all here..." The subordinate put down the intelligence scroll and waited for Danzo to check it.

"Go down," Danzo said, waving his hand lightly to dismiss his subordinates. Tonight's gains were quite good. With these Sharingan reserves, he could begin learning that technique. He also needed to find time to contact Orochimaru.

Aside from the deceased Second Hokage, Orochimaru is the most knowledgeable about the Uchiha clan. To understand the Uchiha's technique and the transplantation of Hashirama's cells, Orochimaru is an indispensable partner. Otherwise, he wouldn't have been so kind as to inform Orochimaru of such a major event as the Uchiha clan's impending extermination.

Then, he put aside his thoughts, slowly unrolled the scroll, and, by the bright candlelight, began to examine it closely…

The information on the scroll indicated that he had his subordinates collect some children with decent ninja talent. Besides training them as his subordinates, another purpose was to transplant Sharingan eyes into them, and then remove them after the Sharingan evolved into the three-tomoe form.

With no other option, the Uchiha clan had only one heir left, Sasuke, who hadn't even awakened his Sharingan. Faced with Itachi's blatant threat, he had no choice but to find another way.

As he read through the information on the scroll, which consisted of information about children from various families and some commoner geniuses, he noticed a name again: Chiba Rinchuan.

Chiba Rinkawa, seven years old, ranked first in his grade, achieved A-rank in all exams, and his strength has reached the level of a Genin. He is proficient in the Three Body Technique, shuriken throwing, and can use four Water Release ninjutsu, including two C-rank ninjutsu, Water Clone and Water Wave, and two B-rank ninjutsu, Water Wall and Water Dragon Bullet.

"What a genius!" Danzo stared at Lin Chuan's file, his eyes gleaming with intense light, and circled Lin Chuan's name.

Then, he looked at the talented young members of the Nara, Yamanaka, Akimichi, Aburame, and Inuzuka clans, picking and choosing...

He ultimately chose the children of the Yamanaka clan and the Aburame clan: Yamanaka Fuu of the Yamanaka clan and Aburame Shino of the Aburame clan.

Finally, he looked at the geniuses in the orphanage and selected several children with good talent. He was waiting to personally test these children to see if they were qualified to be taken under his wing.

He would definitely pick the toughest bone to gnaw on. He planned to visit the major clans first. As long as he could get children from the mountain clan and the oil-woman clan, he could then take children from other clans. Those people would be powerless to resist.

……

The following day, Danzo set off with his subordinates to the Yamanaka clan's territory. The Yamanaka clan was quite tactful in the face of Danzo's arrival. When Danzo specifically asked for Yamanaka Kaze, the clan chief handed him over immediately.

Fortunately, it wasn't the clan chief's daughter he wanted, otherwise he would have struggled to get her. It was just the other members of the mountain clan; if Danzo wanted someone, he would just give them to Danzo.

Danzo was very pleased with the sensible nature of the Yamanaka clan chief. He instructed his subordinates to take Yamanaka Fu back to the Root Clan first, and then he set off for the Aburame clan's territory.

Faced with Danzo's demand for Shino Aburame, Shino Aburame, the head of the Aburame clan, was unable to resist and could only take Danzo to find his son in the forest.

But after finding his son, he discovered that Aburame Torune was also there...

"Is that your son?" Danzo followed behind Shino Aburame, looking at Shino Aburame, who was wearing a hood and sunglasses.

"Yes," Shiki Aburame replied somewhat reluctantly to Danzo.

"This age is perfect for joining Root," Danzo said, pleased with the child's talent. He believed the child would at least become a Jonin in the future. He continued, "You should know that Root is the training institution for the Anbu, responsible for cultivating various talents from a young age..."

"The organization is currently undergoing restructuring, and I hope that someone from the Aburame clan can be selected..."

"Is this the Third Hokage's idea?" Shiki Aburame felt immense pressure facing Danzo, but for his son's sake, he still forced himself to ask. He knew what kind of person Danzo's Root organization was, and naturally didn't want his son to go to such a place.

"I will be in charge of the selection of talent for Root. Families with secret techniques, such as Yamanaka and Nara, must provide talent for Root." Danzo's lips curled up almost imperceptibly. Unless Hiruzen Sarutobi was present, no one could stop him.

"But, Shino..." Shino knew he couldn't escape. If even Yamanaka and Nara sent people, he would have no choice but to obey orders and couldn't resist at all.

"Your son must be very outstanding..."

Suddenly, Shino Aburame noticed her father's serious expression. They had noticed them earlier and immediately asked him, "Father, what are you saying?"

"Shiki, this is an order. I hope you can think it through," Danzo said in a low voice to Shiki beside him when he saw Shino's two children looking in their direction.

"This?" Aburame hesitated slightly. He really didn't want to see his son join the Roots, because that was no place for a human being.

Suddenly, Aburame Torune, standing behind Aburame Shino, stepped forward and smiled confidently at Danzo and the other, saying, "If we're talking about excellence, don't you think I'm capable?"

"You? You don't even seem to be a genin, do you?" Danzo looked at Aburame Torune, who was wearing an eyepatch. He didn't seem to have seen this child before, and his subordinates didn't have any information about him either.

"I am Shiro Aburame's son, and my name is Torune Aburame." Torune Aburame carries nano-poisonous insects. Apart from Shino Aburame, he has no other friends. He didn't even go to the Ninja Academy because he was afraid that the poisonous insects would go out of control and hurt others.

"Shiguro has a son?" Danzo asked, puzzled. He had never heard that Shiguro Aburame had a son who wasn't in school.

"For some reason, Shiguro's son is currently staying at my house," Shiki Aburame said. He breathed a sigh of relief when he saw Aburame Torune step forward, but he was also worried about Aburame Torune. He couldn't let Aburame Torune go with Danzo, or he would be unable to fulfill his old friend's request.

"Oh? Is it inconvenient for him to see people? That's interesting." Danzo had heard of Shiro Aburame, a poison insect expert, and was a Jonin with considerable strength in the village. He just didn't know what abilities Shiro Aburame's son possessed.

"He's a bit older, about two years older than your son," Danzo said, approaching Aburame Torune with an admiring look. "From now on, he will be a Root ninja..."

"Let me make this clear first, I can't partner with anyone," Aburame Torune could only explain to Danzo because of the nano-poisonous insects.

"Put away your arrogance. You're not the only ninja who knows secret techniques," Danzo clearly misunderstood something and didn't know about the nano-poison insects, but it was irrelevant to him. He turned to Aburame Torune and instructed, "Come find me at Root tomorrow morning..."

"Yes," Aburame Tori replied, watching Danzo depart into the distance.

Then he bowed slightly to Aburame Shiki to express his gratitude for her care during this time, and silently went back to his house to pack his things, preparing to enter the Root.
