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

One week later, Monday...

When Iruka saw Lin Chuan arrive at the classroom as usual, he gave up the idea of ​​saying a few words. This kid had really given him a lot of trouble this past week. He would skip class every afternoon to go home, which was the only thing that made him feel relieved.

When asked why he skipped class, Lin Chuan explained that he was just practicing kunai at an outside training ground, adding that he couldn't practice properly at school. He had secretly followed Lin Chuan once and, seeing that Lin Chuan was indeed practicing kunai, he gave up.

As long as Lin Chuan knows to go home, he won't need to run to Lin Chuan's house anymore. You know, there are more than 20 students in the class, and he can't possibly focus all his attention on one student. If he neglects other places, he'll have nowhere to turn for help.

Since we know Lin Chuan's whereabouts, that he goes home by himself after school, that he teaches students shuriken throwing in the afternoon PE class, and that Lin Chuan's throwing skills are quite good, that he's a hardworking kid with his own ideas, we'll just let Lin Chuan do as he pleases.

"Turn to page four in your textbooks. Today we'll be discussing chakra attribute transformations and ninjutsu classifications," Iruka said, having seen all the students present. He then took out his textbook and had the students turn to the page he was going to cover, beginning his lesson.

Ring ring, ring ring—

The morning classes ended quickly, and it was lunchtime again. Lin Chuan took out two lunch boxes, and Naruto couldn't wait to rush over. Every day, lunch was like opening a blind box.

"Lin Chuan, what delicious food is it today?" Naruto asked, holding chopsticks in his hand, licking his lips, his mouth watering.

"This time it's seaweed rice balls and dried fish. This one is for you, Naruto," Lin Chuan said, picking up the bento box from the table and handing it to Naruto. This was after Naruto ordered lunch bento boxes last time.

Naruto paid him 2,400 ryo to cover his lunchboxes for a month. He also told his family about it and asked his mother to prepare an extra lunchbox for 1,200 ryo.

Making one bento box is the same as making two. Cooking in my spare time can earn me some pocket money. 1,200 ryo can buy 20 bowls of Ichiraku Ramen, so my purchasing power is quite good. My mother did not object to this and readily agreed to my request to make an extra lunch.

After lunch, it was time for afternoon PE class. Lin Chuan didn't skip class today because there was a kunai throwing test in the afternoon. Each person threw ten kunai, and the full score was ten points, with six points being the passing score.

Iruka was preparing to assess the children's skill level in kunai throwing. He couldn't help but look at the black-haired, cool-looking Uchiha Sasuke, as well as Hinata Hyuga from the Hyuga clan, the Ino-Shika-Cho trio, and other children from other clans and ordinary people.

The family's children were introduced to kunai throwing early on, so there was no need to worry about their grades. As for Lin Chuan, there was no need to worry about his kunai throwing either. These children were all basically able to pass.

Holding the exam form, he called out to the first name on it, "Uchiha Sasuke, you go first..."

"Uchiha? That Uchiha, right?"

"Ahhh, it's Sasuke!" Sakura Haruno exclaimed excitedly upon seeing Sasuke take the first test, her eyes turning into hearts.

"Sasuke, it's Sasuke!" Ino was so excited that she swooned and leaned against Sakura Haruno. These two were Sasuke's number one fangirls.

"Tch, I just can't stand this guy, always putting on airs like that," Naruto said through gritted teeth, looking annoyed at Sasuke's popularity and the many girls who were cheering for him.

"Hehe, if you were as handsome as him and as fair-skinned as him, you could look like that too. If you can't even do modeling, then stop being sour," Lin Chuan said, arms crossed, with a mocking expression.

Sasuke's character design is something even Kishimoto acknowledges; he's the most handsome character in Naruto, even more so than Kishimoto himself. If he hadn't transmigrated, the original owner would have been just a roadside weed, an unknown passerby.

"Hey, Lin Chuan, whose side are you on? Why are you taking his side?" Naruto was genuinely annoyed. He had thought that he and Lin Chuan were friends and could stand together against a common enemy!

"Wow, nine points! That's amazing!" A girl screamed, letting everyone know Sasuke's score in the kunai throw.

"Good job. Next up, Nara Shikamaru," Iruka said, looking at Shikamaru leaning against a tree. He had heard about the personalities of the ninjas from this clan; they all disliked troublesome things.

"What a hassle," Shikamaru muttered under his breath, lazily got up, went to the kunai throwing target, picked up a kunai and threw it randomly, scoring eight points.

Seeing that his last kunai missed, Shikamaru breathed a barely perceptible sigh of relief. He didn't want to steal Sasuke's thunder; for him, being the center of attention was a troublesome thing.

"Eight points, not bad, next up, Naruto Uzumaki..."

"Hahaha, it's finally my turn! Watch me get ten points!" Naruto stepped forward triumphantly, then returned dejectedly, his entire body now a gray backdrop, accompanied by bursts of laughter.

"Naruto Uzumaki, one point, failing grade," Iruka said, his forehead creased with annoyance. He couldn't bear to watch Naruto's performance; it was just too bad.

Next, he called out many more names in succession, "Akimichi Choji, Hyuga Hinata, Inuzuka Kiba, Aburame Shino, Yamanaka Ino..."

As each child stepped forward to throw kunai, most scored seven or eight points, with none scoring nine. Sasuke breathed a sigh of relief upon seeing this; no one could surpass him, and he remained number one.

"Tsk, Shino really doesn't have much of a presence," Lin Chuan said, looking at Shino, who was completely covered in his collar and wearing sunglasses. Iruka called out the other's name and only then did he notice that the other was right next to him. He really was a ninja with a very low presence.

"Next, Chiba Rinkawa," Iruka said, looking at the problem student who liked to skip class. Which teacher doesn't like a student with good grades? But this student with good grades was a problem student.

"It's this guy's turn," Shikamaru glanced at Lin Chuan. He had secretly followed him last week and knew how strong he was. A mere kunai throw was no challenge for him at all.

Swish swish, swish swish——

Lin Chuan threw ten kunai in a row, each one hitting the bullseye, leaving everyone stunned.

Some people can do it, but don't want to. Others are truly unable to do it, which is why they feel that hitting the bullseye with ten kunai is amazing.

As for Sasuke, he probably made a mistake by accident, which is why he missed hitting the bullseye with one kunai.

He can throw a fixed-target kunai two hundred times in a row, missing the bullseye only twice. Here are just ten kunai throws, which is a piece of cake for him.

In order to exploit Naruto, he needs to establish a genius persona from now on, making it more natural for him to approach Naruto later, since geniuses always have many privileges.

Otherwise, do you really think anyone can get close to Naruto at this time?

At this time, the people who could have contact with Naruto, besides Sarutobi and the Anbu protecting Naruto, were mostly his classmates. And the classmates who could freely contact Naruto and did not reject him were only the Ino-Shika-Cho trio of the Hokage lineage, and he was now one of them.

"Chiba Rinkawa, 10/10," Iruka paused, his fingers holding the pen still pausing. He had already witnessed Rinkawa's kunai throwing, but seeing this performance again still shocked him.

This child is only six years old, and he's already mastered kunai to this level. Even the Uchiha clan...
