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

Meanwhile, the Death Forest—

Lin Chuan, dressed in the standard equipment of the Dark Division, was fighting a wild boar. After four months of training, missions, and kiting wild boars, he finally had the confidence to fight a wild boar.

The wild boar still couldn't touch the hem of his clothes, and he even slashed it all over. Because his previous short knife had become dull from using it to cut people, he replaced it with a longer short knife when he returned from the mission.

*Pfft, boom—*

With his final thrust, he plunged the knife into the boar's neck, then quickly abandoned the dagger and retreated. The boar collapsed to the ground, struggling for a moment before losing all its breath.

"Phew, this is really tough to deal with," Lin Chuan said, looking at the 1.5-meter-long wild boar. It took him more than half an hour to finally take it down. At first, he was chased around by the wild boar, which was as tough as a bull.

Just as he was about to draw his dagger to butcher the wild boar and make it into jerky for his reserves, he suddenly heard a loud bang, and a firework exploded in the woods not far from him.

He instantly abandoned the plan to divide the wild boar, immediately raised his hand to form a hand seal to create a shadow clone, while his main body hid. A whooshing sound came from the forest, and a dark shadow appeared in front of him in an instant.

"Hmm? Anbu?" Lin Chuan looked at the ninjas who appeared around him. Some were standing on trees, some on the ground, and some on the cliff protrusions. All of them were looking at him below through the eye holes of their masks.

Looking at the ANBU members around him, each of them exuded an aura of at least a Special Jonin. He couldn't defeat any of them, but he couldn't lose in terms of momentum. He immediately drew his bloodstained dagger and warily watched the ANBU members around him.

"This child? Root?" Kakashi peered through the eye holes of his fox mask at the child below, who was covered in blood and sweat. A child this age hunting a wild boar all by himself, that's truly remarkable. Could it be that the Hokage came for him?

Whoosh whoosh—

Because of the fireworks earlier, several more whooshing sounds came from the woods again, this time with even more people arriving.

The first to appear was Danzo, covered in bandages. He immediately noticed Lin Chuan on the grass, as well as the Hokage's ANBU members around him. He also took a second look at the fox mask, recognizing its owner.

"Chuan, come here," Danzo knew he couldn't wait. He had to take Lin Chuan back now, or Hiruzen Sarutobi would intercept him, and the meat that was already in his mouth would be gone.

"Yes, Lord Danzo," Lin Chuan immediately knelt down on one knee upon seeing Danzo. He finally understood what was going on. The first Anbu to arrive should be the Hokage's direct Anbu. Sarutobi Old Deng might have come looking for him.

But since Danzo had arrived, he had no choice but to obey orders and go to Danzo's side. If he went now, he could still live; if he didn't go now, he would only die. He knew too well what kind of person Root was.

"You can't go over there," Kakashi said as he saw Lin Chuan draw his short sword and walk towards Danzo. He immediately jumped down from the tree, stood in front of Lin Chuan, and raised his hand to block him.

At the same time, the ANBU squad that came with Kakashi all stood behind Kakashi, surrounding Lin Chuan in the middle.

"Lord Danzo," Lin Chuan said, seeing that his path was blocked, he could only pass the problem on to Danzo and ask him to come up with a solution.

"Kakashi, you deserve to die!" Danzo looked at the fox mask. He hated this traitor to the core. Otherwise, his Wood Release ninja, Tenzo, wouldn't have been taken away by Hiruzen Sarutobi.

"Kakashi, you did a great job..."

Suddenly, a voice that Danzo disliked rang out, and everyone looked at the old man who emerged from the woods, calling out in unison, "Hokage-sama..."

"Hmm," Hiruzen Sarutobi nodded slightly in response, then looked at Danzo Shimura and said calmly, "Danzo, Konoha isn't a place for you to run wild..."

"Hiruzen, I'm just training useful talents for the Anbu," Danzo knew his actions were dishonorable, but he couldn't afford to lose morale.

"Since it's about training talent for the Anbu, I think this kid has great talent, so let him join the Anbu," Hiruzen Sarutobi glanced at Danzo, sighing inwardly that Danzo was still the same as ever, offering him an excuse. He really hadn't improved at all.

"Hiruzen, you can't do this! This is a talent I've painstakingly nurtured!" Danzo was furious. He had done the same thing with Tenzo last time, and now he was doing the same thing with Rin. Hiruzen Sarutobi was pushing his luck.

"Danzo, you shouldn't have done this! Didn't you ask before taking people in? Didn't you know Ogawa has a teacher's child?"

"What? Kawa has a teacher?" Danzo looked at Lin Chuan in confusion and asked, "Kawa, who is your teacher?"

"Lord Danzo, my teacher is Mr. Maruboshi Kosuke," Lin Chuan had already seen Maruboshi Kosuke, who was following behind Hiruzen Sarutobi, but he dared not show any joy. His face remained expressionless, as cold and indifferent as a dead man.

"Maruboshi Kosuke," Danzo finally understood who wanted to take Lin Chuan away, but Maruboshi Kosuke...

Whenever he thought of Maruboshi Kosuke, he would recall his childhood memories. They were not only classmates with Maruboshi Kosuke, but also subordinates of the Second Hokage. However, Maruboshi Kosuke became greedy and reckless, causing the death of his comrade. After that, he refused to be promoted to Jonin and remained a Genin. He had almost forgotten about this person.

"Knowing that Ogawa has a teacher, why did you still ask him to join Root? Couldn't Ogawa's teacher teach his own disciple?" Hiruzen Sarutobi struck Danzo again. This guy really doesn't learn his lesson!

"Hiruzen, you—" Danzo knew he couldn't win an argument with Hiruzen Sarutobi, so he turned to Lin Chuan again and asked, "Chuan, prove to me that you are Kosuke's disciple..."

"Yes, Lord Danzo," Lin Chuan said, plunging his bloodstained dagger into the grass. He quickly formed hand seals, completing six in an instant, and whispered, "Water Release: Water Dragon Bullet..."

Roar--

A water dragon suddenly appeared out of nowhere on the dry grass and crashed into the cliff not far away, making a loud rumbling sound, shaking down a lot of rocks and leaving a crater.

Neither the water dragon bullets nor the falling pebbles affected the ninjas present. After all, which of the ninjas present was a Jonin? Why would they be afraid of some small stones?

The fact that a child could instantly unleash a Water Dragon Bullet really startled them. After all, he was just a child, yet he could use the Water Dragon Bullet so skillfully. Such a level of ninjutsu was already at the Chunin level.

"A simplified version of the Water Dragon Bullet," Danzo's expression darkened when he saw the Water Dragon Bullet. The intelligence his subordinates had gathered only said that Lin Chuan could use the Water Dragon Bullet and the Water Barrier, but it didn't say that it was a simplified version.

"Let's go," Danzo said, knowing that he couldn't take Lin Chuan, this genius, with him no matter what. He took one last look at Lin Chuan and left with his subordinates, unwilling to give up.

"Ogawa, long time no see. You've gotten even stronger." Hiruzen Sarutobi breathed a sigh of relief as Danzo retreated, thankfully avoiding a conflict with him. He then looked down at Lin Chuan with a kind smile.

"Yes, Lord Hokage," Lin Chuan knelt on one knee before the Hokage, still expressionless, acknowledging his change.

"This child," Hiruzen Sarutobi sighed softly as he saw that Lin Chuan's expression remained unchanged. From the arrival of the Anbu until his own appearance, the child had not shown any emotion.

Root really knows how to teach children. In just a few months, he has tormented a lively, active, intelligent and sensible child into this state. Danzo deserves to die. Did he want to destroy the village's genius?

"Alright, let your real body come out," Kakashi said, reminding the Third Hokage that this was just a shadow clone, seeing that Lin Chuan remained expressionless.

"How could this be? Captain, you're not kidding, are you?" The Anbu members around them broke out in a cold sweat when they saw Kakashi saying that this Lin Chuan was fake and looking very serious. This joke had gone a bit too far.

"How could this be?" Lin Chuan's expression changed at this moment. He pretended to look at Kakashi with a surprised expression, and saw the Sharingan behind Kakashi's mask. He thought to himself, "It's the Sharingan, huh? That's really sharp..."

slam-la-

Knowing he had been exposed, Lin Chuan, who was hiding in the water, jumped out and landed soaking wet in front of Sarutobi Ryouto and Maruboshi Kosuke. He knelt on one knee and called out to the two of them, "Hokage-sama, Kosuke-sensei..."

"A very good kid," Hiruzen Sarutobi was also shocked to hear that the Lin Chuan they were fighting over was a fake, because even he hadn't figured it out. If Kakashi hadn't pointed it out, he would have almost given himself away.

"When did you use Shadow Clone Technique?" The other ANBU members were very puzzled, not understanding how the other party could use Shadow Clone Technique right under their noses.

Faced with the Anbu's questioning, Lin Chuan dared not hide anything and truthfully replied, "I heard the sound of fireworks, so I used Shadow Clone Technique..."

"No wonder, it was the captain who gave the signal. At that time, only the captain should have seen that this kid used Shadow Clone Jutsu." The Anbu members all looked at Kakashi, not expecting that this was how they discovered it. They thought it was the captain who had noticed it.

Kakashi was also embarrassed. After finding Lin Chuan, he used his Sharingan to observe him. Although the Sharingan's vision was not as good as the Byakugan, he could still distinguish whether an object was one or two by observing the flow of chakra.

When Lin Chuan heard the fireworks, he immediately created a shadow clone. He also saw the main body hiding in the water, but he didn't point it out immediately because Danzo was present. Moreover, this child did a good job and is a child who knows how to protect himself.

"Ogawa, are you alright?" Maruhoshi Kosuke finally had a chance to step forward and check on Lin Chuan, pinching and squeezing him here and there. Seeing that Lin Chuan was not missing any limbs, he finally felt relieved.

"Teacher Kosuke, I'm fine," Lin Chuan shook his head gently. He was doing quite well staying at the Root. All training supplies were free, which was much more cost-effective than paying for them himself. However, he had less freedom and could only wander around the Death Forest.

"Kosuke, we shouldn't stay here any longer. If we want to catch up, we should go back first," Hiruzen Sarutobi said, looking at the setting sun. It was getting dark, and they should head back soon. The Hokage Tower couldn't do without him.

"Yes, Lord Hokage," Maruboshi Kosuke replied, then led Lin Chuan away from the Forest of Death.

"Kakashi, go," Hiruzen Sarutobi said, looking at Kakashi and instructing him to follow Kosuke Maruboshi and the other man.

"Yes," Kakashi accepted the order and led his ANBU squad to chase after Lin Chuan and the other two.

Next, Hiruzen Sarutobi, along with his ANBU guards, headed towards the Hokage Building. Upon returning, Homura Mitokado and Koharu Utatane came looking for him, demanding to know what conflict had occurred between Hiruzen Sarutobi and Danzo.

……

Meanwhile, Lin Chuan and his companion, having left the Forest of Death, successfully returned to Konoha under the escort of the Anbu, after which the Anbu returned to the Hokage Building.

After returning to the Hokage Building, the Anbu members chatted briefly about the mission. One of them asked Kakashi, "Captain, this kid is a promising talent. Should we ask the Hokage to let him join the Anbu...?"

"Forget about sending him to the Anbu," Kakashi said, looking at his teammates with a hint of exasperation. "That kid's only seven, a second-year student at the Ninja Academy, and you didn't even detect his shadow clones. Keep up the extra training tonight..."

"No, Captain, I want to take a nice shower and go back to my girlfriend's place to sleep..."

"Only seven years old? Could he be another genius like the Uchiha clan...?"

"Hey, you can't say that name. Watch your mouth," Kakashi's lips twitched. These clowns really dared to say anything. Uchiha Itachi was a very talented ninja he had ever seen, but that kid was still far from Itachi's level.

However, he felt that Itachi's younger brother probably couldn't beat that kid. He really didn't know what the Third Hokage was thinking, sending a kid with Chunin-level strength to the Ninja Academy.

Never mind, it's none of his business. He hasn't read the new "Make-Out Paradise" yet; he's going to binge-watch it...

……

At the same time, Lin Chuan and Maruhoshi Kosuke returned to Lin Chuan's wooden house. Seeing the familiar wooden house again, Lin Chuan was almost moved to tears. After living in a cave for several months and camping for another month, he was finally able to sleep in a soft and comfortable bed. How could he not miss it?

But before he could be happy for long, he collapsed to the ground, his body going limp instantly. His last thought before losing his sight was that he had finally escaped. Then he completely lost consciousness. These were the symptoms of losing too much chakra.

Fortunately, he did not use chakra when fighting the wild boar, and his shadow clones also allocated enough chakra to each other in case of emergencies.

Because his main body only needed to hide and didn't need to do anything, his chakra was almost depleted, and there was also the side effect of the shadow clones disappearing. He couldn't hold on any longer when he got home.

Don't be fooled by the fact that Naruto can instantly create hundreds or thousands of shadow clones, and even if the shadow clones explode, it doesn't matter, because his constitution is different.

Naruto possesses the physique of the Uzumaki clan, while he only has the physique of an ordinary ninja. To put it more vividly, using the analogy from cultivation novels, Naruto is like a born saintly body, naturally suited for cultivation and naturally suited to be a ninja.

These ordinary junior ninjas push their bodies to their limits, barely managing to become qualified ninjas. Just meeting the standard of being qualified already takes all their effort.

"Ogawa? Kosuke-senpai? What's going on here?" Lin Chuan's father heard a noise in the backyard, opened the door and saw Maruhoshi Kosuke and Lin Chuan in the backyard. He couldn't hide the joy on his face.

"Let's go inside and talk," Maruhoshi Kosuke said, picking up Lin Chuan and carrying him to the bedroom. He gently put Lin Chuan down and saw that Lin Chuan had fallen into a coma. He could only go to the kitchen with Lin Chuan's father and tell him about how they found Lin Chuan.

Of course, he didn't mention the part where he asked Hiruzen Sarutobi for help; he just wanted the other party to know that he was the one who brought Ogawa back and that he had done his job.

He also told Lin Chuan's father that he had been promoted to Jonin and would not be going on missions as frequently anymore. He would teach Lin Chuan more ninjutsu so that Lin Chuan could become stronger as soon as possible.

After this incident, not only Lin Chuan's father, but even he himself felt a sense of urgency. They couldn't watch over and protect Lin Chuan all the time.

Moreover, they couldn't protect Lin Chuan even against someone like Danzo. The best way to protect Lin Chuan was to help him grow up as quickly as possible and develop the ability to protect himself. That would be the best outcome.

"I understand, Kosuke-senpai," Lin Chuan's father bowed solemnly to Kosuke, his forehead touching the ground, and pleaded with Maruhoshi Kosuke, "Kosuke-senpai, please train Ko Chuan. I will find a way to provide Ko Chuan with all the training he needs..."

"I understand. There's no need to worry about the training. As Ogawa's teacher, I've accumulated a considerable amount of experience from doing missions for so many years," Maruhoshi Kosuke looked up at the window. For the past fifty years, he had never stopped, plunging headlong into the sea of ​​missions, constantly doing them.

Because of this incident, I might be able to stop and take a good look at this new generation of Konoha. The Second and Third Hokage probably had the same intention, but unfortunately, I didn't see it clearly for so many years, nor did I understand the intentions of the two lords.

However, it's not too late now. I will cherish my remaining time and nurture outstanding successors for Konoha...
