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

Meanwhile, the Anbu followed Naruto and Sasuke away, the clever ones already guessing what the two kids were up to.

"Captain, if they really are going to look for the Jonin teacher, I have a feeling that it will be you," Tenzo couldn't help but wink at Kakashi, because he had also heard rumors that Kakashi was going to leave the Anbu.

"Shut up," Kakashi didn't want to be someone else's babysitter, especially that little kid who always had a grumpy face.

The Hokage Building, the Hokage's office. Naruto often came here to cause trouble, so he knew that the old man worked here. They quickly found their way to the Hokage's office and met Hiruzen Sarutobi.

"Oh? Naruto, what brings you here? And Uchiha Sasuke too?" Hiruzen Sarutobi knew that the Anbu must have let these two in, otherwise they wouldn't have been able to get in.

"Grandpa, I've finally found you! Help me find a teacher!" Naruto ran over and hugged Hiruzen Sarutobi's leg, begging him to help him find a teacher.

"What teacher? What teacher are you looking for? What's going on?" Hiruzen Sarutobi was still dealing with official business when he heard about the teacher, leaving him completely bewildered.

"Here's the thing, we want to become stronger. Lin Chuan said that to become stronger, we need to find a teacher, so we came to find you, grandpa..."

"Oh, is that so? You want to get stronger, huh?" Hiruzen Sarutobi couldn't help but laugh when he heard little Naruto say he wanted to get stronger. A kid this young wants to get stronger? He probably doesn't even know what getting stronger means!

However, since Naruto had this intention, he couldn't ignore it. It would be good to find Naruto a teacher to prevent him from causing trouble at the Hokage Rock.

"By the way, grandpa, my chakra is wind-style, so I need to find a wind-style teacher, and they have to be a Jonin..."

"Wind Release? Jonin teacher?" Upon hearing Wind Release, Hiruzen Sarutobi immediately thought of his old friend, Danzo Shimura, who was a master of Wind Release.

It's impossible to hand Naruto over to Danzo. If it's about choosing a teacher, his son Asuma is also a Wind Release ninja, but Asuma is having a conflict with him and has gone to the capital of the Land of Fire to protect the Daimyo.

Aside from these two Wind Release ninjas, it seems there are no other Wind Release ninjas who can put his mind at ease.

Hiruzen Sarutobi fell into deep thought, unsure who to find as Naruto's Wind Release instructor. Suddenly, as if struck by a thought, he looked at Sasuke Uchiha and asked, "Sasuke, did you come here also...?"

"Yes, Hokage-sama, please find me a Jonin teacher as well. My chakra nature is lightning." Sasuke naturally recognized the Hokage, but he wouldn't be as brazen as Naruto in fawning over him, and besides, he couldn't bring himself to do it.

At this point, he finally knew who the old man Lin Chuan had mentioned, the old man who often brought Naruto living expenses, was. He never expected that it would be the Third Hokage, Hiruzen Sarutobi. It seems that Naruto's identity is not ordinary!

"A Lightning Release Jonin, Kakashi," Hiruzen Sarutobi sighed inwardly. There weren't many Lightning Release Jonin in Konoha. If Sasuke could be entrusted to a reliable Lightning Release Jonin who could also teach Sasuke, who had the Sharingan, then there was only one person left who could teach Sasuke.

"Kakashi, Tenzo," Hiruzen Sarutobi knew the two were nearby, and he called out their names directly.

"Lord Hokage," Kakashi and Tenzo appeared instantly, kneeling on one knee beside the Hokage's desk. They knew that what was coming would eventually come.

Unexpectedly, the Hokage actually called him. Tenzo was speechless. He had originally wanted to see Kakashi make a fool of himself, but now he couldn't. He was going to have to be a babysitter.

"Kakashi, Sasuke wants to find a Jonin teacher, so Sasuke is in your care," Hiruzen Sarutobi solemnly announced, looking at Kakashi wearing the fox mask. "From today onwards, you will leave the Anbu and become a Jonin leader. In your spare time, you can tutor Sasuke..."

"Yes, Hokage-sama," Kakashi removed his Anbu mask, revealing his Sharingan, which Sasuke saw.

"Sasuke, the teacher I found for you is Kakashi. Do you accept it?" Hiruzen Sarutobi looked at Sasuke Uchiha. Itachi had entrusted him with the care of his younger brother, so he naturally took it very seriously. Otherwise, he wouldn't have arranged for Kakashi to be Sasuke's teacher.

"Lord Hokage, is he a Jonin?" Sasuke had never heard of the cold-blooded Kakashi, but he had seen Kakashi's Sharingan. Now was not the time to be curious about that; he had to find out Kakashi's strength.

"He's a Jonin, and a very powerful one at that," Hiruzen Sarutobi answered truthfully. Kakashi was indeed very powerful; after all, Kakashi was a genius in his prime.

"I accept, Hokage-sama, Kakashi-sensei," Sasuke said, curious about the Sharingan in Kakashi's eyes after hearing that Kakashi was a Jonin.

Kakashi's face behind the mask remained expressionless, and he didn't look at Sasuke. He really didn't want to take care of the child, especially since the child was Itachi's younger brother. He was unaware of Itachi's secret deal with the Konoha leadership.

"Alright, Kakashi, Sasuke, you can go now," Hiruzen Sarutobi said, letting the two leave first, as he had other plans for Naruto.

After Kakashi and Sasuke left, Hiruzen Sarutobi looked at Tenzo. Although he wasn't a Wind Release ninja, Tenzo knew some Wind Release techniques. Jonin learn ninjutsu much faster than Genin, and Tenzo's Wind Release was enough to deal with Naruto.

He then ordered Tenzo, "Tenzo, you should also leave the Anbu. From now on, you will serve as Naruto's teacher and protect him closely. I will give you a long-term mission, and you will receive payment for your protection mission every year..."

"Yes, Lord Hokage," Tenzo also took off his mask and looked at Naruto with dead fish eyes. Naruto shrank back behind the Third Hokage.

"Little Naruto, don't be afraid. This is the Wind Release Jonin teacher I found for you. He's really amazing," Hiruzen Sarutobi laughed when he saw that Little Naruto was scared, and patted Little Naruto's head.

"Grandpa, can he beat Lin Chuan's teacher?" Naruto wasn't afraid, but he really wanted to know who was stronger.

"Haha, of course you can beat him. The teacher I chose for you is the best." Hiruzen Sarutobi was speechless for a moment. He knew that Naruto wasn't choosing a teacher to become stronger, but to be better than others. He then smiled at Tenzo and said, "Tenzo, you should change your name. From now on, you'll be called Yamato..."

"Yes, Hokage-sama," Yamato still had a deadpan expression, perhaps from spending too much time with Kakashi.

"Go, Yamato. Take Naruto to buy some daily necessities. Move to the apartment next to Naruto's. Find some time to connect the two apartments together so it will be easier to take care of Naruto," Hiruzen Sarutobi waved his hand, and Yamato took Naruto away.

Yamato is a Wood Release ninja, so it would be perfect for him to be Naruto's teacher. If Naruto were to lose control, Yamato could immediately suppress the rampaging Nine-Tails.

It's just unknown how much Naruto will learn with his own teacher.

I wonder where Jiraiya is. The most suitable person to be Naruto's teacher should be Jiraiya. We need to send someone to find Jiraiya. As Naruto continues to grow up, it's time for Jiraiya to lend a hand.

There were also members of the Uchiha clan. Hoping Sasuke could get along well with Kakashi, Hiruzen Sarutobi went to the window, watching Yamato and Naruto gradually disappear into the distance. Thinking of Itachi who had left, he murmured to himself, "Don't worry, I'll take good care of him..."
