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

Three years later, at the Ninja Academy, the graduation exams have ended, and today is the day for class assignments and team formation.

"Naruto, how did the exam go?" Lin Chuan entered the classroom, passed Naruto's desk and raised his hand to greet him. This time, Naruto was no longer the bottom-ranked student who couldn't even pass the graduation exam.

"I passed! I've got the headband!" Naruto raised his thumb to his forehead and grinned as he showed Lin Chuan the headband, a testament to his years of hard work.

In the Naruto anime, only Naruto failed the exam, but this time everyone passed, and they all reached Chunin level before graduation, which is much stronger than in the anime.

"Congratulations on becoming independent ninjas from today onwards. However, you are still only genin. The real hard work has just begun. From now on, you will be divided into groups of three, forming a squad, and will carry out missions alongside a jonin instructor..."

Seeing that everyone was listening attentively, Iruka continued to explain the precautions for becoming a genin, "In order to ensure that the abilities of each class are balanced, the teachers will decide on the group assignments, so I will now announce the group assignments..."

"Team One is... Team Two is... Team Seven is... Naruto Uzumaki, Sakura Haruno, Sasuke Uchiha..."

"Team 8 consists of Hinata Hyuga, Kiba Inuzuka, Shino Aburame..."

"Class 9, Chiba Rinkawa..."

"Class 10: Ino Yamanaka, Shikamaru Nara, Choji Akimichi..."

"Tsk, as expected, they're all just passersby," Lin Chuan said helplessly. He thought he could at least team up with some minor characters with names and identities, but he didn't expect that both of his teammates were just passersby. He wondered who the team leader was.

After the group assignments were completed, Iruka-sensei told everyone to wait, as the Jonin leading the teams would come and take them away.

Before long, the other Jonin, Kurenai Yuhi, Asuma Sarutobi, and others arrived at the classroom and took their students away.

Until a man with a scar on his lip, wearing a green Konoha Jonin vest, sharp eyes, a ponytail, and carrying a katana, glanced around the classroom and shouted to the remaining students, "Class 9, come out with me..."

"Here he is. Just looking at his aura, he exudes power," Lin Chuan licked his lips, quite satisfied with this powerful Jonin leading the team.

He had assumed that the Jonin leading the team would be his teacher, Maruboshi Kosuke, but he was quite surprised to find that it was this Jonin.

He and two other passersby, Passerby A and Passerby B, followed the Jonin leading the team out of the classroom and arrived at a training ground. The Jonin then stopped, his sharp eyes like blades, and quickly scanned Lin Chuan and the other two as he introduced himself.

"My name is Shirakumo Hayato, a Jonin of Konoha. From now on, I will be your team leader Jonin. Before I become your team leader Jonin, please introduce yourselves..."

"My name is Chiba Rinchuan. I like to train alone and hate being disturbed during my training," Rinchuan introduced himself first, then looked at the two passersby next to him.

"Who likes training? What are you pretending for?" Passerby A scoffed disdainfully. He had always disliked Lin Chuan because the guy often skipped class. Nevertheless, he continued his self-introduction: "My name is... I like ramen, and I hate being rushed..."

"My name is... I like to eat barbecue, but I hate that there isn't enough barbecue," said Passerby B, who was quite cheerful and didn't seem to care about the conflict between the two people.

"Very good. Now that you've finished your self-introductions, let's begin the next test. Only those who receive the bell can become my subordinates and be considered qualified genin. Otherwise, go back to the ninja academy..."

Bai Yun took out two bells and hung them on her waist in the morning. She looked at the three of them expressionlessly and continued, "There are only two bells, which means that even if they are both taken away, one of you will still have to go back to school..."

"Hehe, first come, first served," Passerby A glanced at his teammates on both sides, chuckled to himself, and was the first to rush forward with a kunai, trying to snatch the bell.

"Idiot," Lin Chuan cursed under his breath, lowering his eyes and retreating into the woods instead of advancing. His opponent was a Jonin; it wouldn't be so easy for him to snatch the bell.

Meanwhile, only Passerby B remained standing in the middle, making no move, unsure of who to follow, and deeply conflicted.

Bai Yunzao saw all of this. The three of them performed adequately, except for the fat man, whose performance was the worst.

"The bell is mine!" Passerby A got closer and closer to the bell. Out of the corner of his eye, he saw Lin Chuan retreating and the fat man standing still. Instead, he became excited.

Once you get two bells and eliminate both of them, the Jonin leading the team will only have one subordinate and only one student.

"Sigh," Bai Yun sighed softly in the morning. Just before the passerby was about to touch his bell, he kicked him in the stomach, sending him flying into the woods without even drawing his knife. He couldn't help but sigh, "That's terrible. Didn't your teacher teach you that when facing an enemy whose situation is unknown, you need to observe the situation first...?"

"You're right," Lin Chuan appeared in front of Bai Yunzaojian in a flash, his short knife already drawn, and he slashed at Bai Yunzaojian.

"Such a fast teleportation technique!" Bai Yunzao immediately drew his sword to block, but there was another Lin Chuan behind Lin Chuan. The two Lin Chuan appeared at the same time, with no difference even in the blink of an eye. He kicked both of them in one kick, hitting Bai Yunzao in the abdomen and sending Bai Yunzao flying into the river.

Splash, splash—

The white clouds had just fallen into the river that morning when the water churned instantly, and heads emerged, immediately coalescing into the shape of Lin Chuan, each holding a short sword, and whispering, "Dance of the Crescent Moon..."

shhhhh--

One after another, sword-drawing techniques flashed by, the sword light and shadows coming swiftly and fiercely. Bai Yun could only passively defend, constantly raising his sword to parry, and occasionally breaking through one of the water clones.

Suddenly, Bai Yunzaojian realized something was wrong; his space was shrinking. Only when the steel cable tightened did he realize he was trapped. He immediately brandished his sword and shouted, "Vacuum Sword..."

shhhhh--

A flash of light appeared, and the blade instantly unleashed a powerful gust of air that swept outwards, blowing away the incoming water clones, cutting the tightened steel cables, and causing the water clones to shatter due to the cutting force of the wind blades.

"Shadow Clone Technique with Shuriken," Lin Chuan's main body stood on the shore, throwing the shuriken towards the white clouds in the river below, while simultaneously raising his hands to form hand seals, releasing the second A-rank ninjutsu he had learned in the past three years.

"Not good!" Bai Yun saw the rapidly approaching shuriken quickly multiply, one becoming ten, ten becoming a hundred, a hundred becoming a thousand. In an instant, a single shuriken transformed into a dense rain of droplets, hurtling towards him. He gripped his sword hilt again and swung his blade at the numerous shuriken: "Vacuum Sword..."

Swish, swish, ding-ding-ding—

Numerous shuriken collided with the wind blades and were instantly bounced away. The steel cables binding the shuriken also flew everywhere. The shuriken's attack trajectory was changed, and they collided with each other and disappeared, but many shuriken and steel cables were preserved.

Just then, Baiyun Zaojian didn't notice that a bell got caught at the intersection of the two steel wires. As Baiyun Zaojian swung his knife and twisted, the bell was also caught on the steel wire and pulled off Baiyun Zaojian's waist.

Hearing the bell ringing suddenly fade into the distance, he snapped out of his daze and realized he'd dropped one. Just as he reached for it, Lin Chuan drew his sword and charged again: "Captain Zaojian, don't get distracted during the battle! Crescent Moon Dance..."

Three more fierce attacks came from three different directions, and Bai Yunzao could only swing his sword to block them again, letting the bell fall into the water.

Just as the bell fell into the water, Bai Yunzao once again swung the Vacuum Sword, and the wind blades instantly covered the three water clones that rushed towards him, cutting them in half.

"Another water clone?" Bai Yun saw the water clone in the morning, but didn't have time to think about it. She didn't understand why Lin Chuan always used water clones. She just wanted to retrieve the bell that was bobbing up and down in the water.

But as soon as he put his hand into the water, a hand grabbed his wrist, and the water surged up and enveloped Bai Yunzaojian's entire body, trapping him on the surface of the water and making him unable to move.

"Captain Morning, you've fallen for their trap," Lin Chuan emerged from the water, one hand on the water sphere to maintain its state, the other holding a bell that he shook, making a tinkling sound.

"Kid, you're celebrating too soon," Bai Yun's scarred lips curled into a slight smile. So what if his limbs couldn't move? His ninjutsu didn't require hand seals. "Vacuum Sword..."

buzzing-

It was the Vacuum Sword again. Bai Yunzao's long wind sword immediately vibrated violently, releasing extremely powerful cutting wind blades that slashed around the water sphere. The wind blades easily cut the water sphere into pieces, including Lin Chuan outside the water sphere, who was also cut into pieces and water flowed out.

"Another water clone," Bai Yun looked around in the morning. As the water gradually calmed down, he noticed that Lin Chuan was not emerging. Suddenly, his eyes were shrouded in shadow. He looked up and saw that Lin Chuan was standing on the shore.

"Captain Morning, here's the bell," Lin Chuan said with a smile, taking out a bell. The continuous interference and attacks had exhausted him, and he had very little chakra left. He had given it his all to get the bell.

Although he was attacking Baiyun Zaojian, his real goal was the bell. It was unrealistic to try to snatch the bell from a top swordsman, so he let the top swordsman make a mistake.

After all, this Jonin was using Wind Release, and anything could happen under the turbulence of Wind Release, including the bell falling off by itself, being tripped by the wire, or being cut off by the wind blade.

"Your performance was quite good." Bai Yun saw the bell in Lin Chuan's hand earlier and sheathed his Changfeng Sword. In his opinion, it was already quite impressive that this genin had forced him to use the Vacuum Sword four times.

Not everyone can withstand his four Vacuum Sword strikes. The opponent's performance was completely unlike what a genin should have, far exceeding his expectations. He thought that all the new recruits would fail again, but there was an unexpected surprise.

Meanwhile, the other two who had arrived at the riverbank were still stunned by the battle they had just witnessed. The wind blades whipped up by the Vacuum Sword made it impossible for them to get close, and even many of the trees along the riverbank had been cut down. They couldn't even get close to the edge of the battle between the two. The Konoha Jonin were terrifying indeed.

Seeing Lin Chuan smiling at them, Passerby A and Passerby B, the fat guy, both swallowed hard. Only now did they realize just how strong Lin Chuan, who often skipped classes, really was, and their initial contempt vanished.

"There's another bell, do you want to steal it?" Lin Chuan smiled at the two passersby, pointing to the bell on Bai Yunzao's waist, which also had another one hanging there.

"Gulp, no, I won't steal it anymore," Passerby A swallowed hard. He finally understood the strength of the Jonin, Shirokumo Zaojian, and no longer wanted to steal any bells.

"I won't try to take it either," said Passerby B, waving his hand to indicate that he wouldn't try to take the bell. It was impossible to snatch the bell from a Jonin like that.

"You two failed. Go back to school now," Bai Yun said, leaping out of the river and standing between the three to formally announce the test results: "Only Lin Chuan passed this test and will become my subordinate..."

Watching the two passersby walk away forlornly, Bai Yun felt no regret. Ninjas who lacked strength, or even those with mental problems, were not suited to be ninjas; becoming ninjas would only harm them.

Only after the two disappeared did he turn to Lin Chuan and express his approval: "Chuan, your strength is not bad. You can go on missions with us. Once you have accumulated enough missions, I will recommend you to the Hokage to become a Chunin..."

"Don't I have to take the Chunin Exams?" Lin Chuan wanted to try the Chunin Exams for fun, but he didn't want to become a Chunin so quickly. The increase in ninja rank also meant an increase in danger, and he didn't want to die during a mission.

"With a Jonin as a guarantor, it's fine whether I participate in the Chunin Exams or not," Baiyun shook his head slightly in the morning. The purpose of the Chunin Exams is to examine the outstanding ninjas of each village, not the only way for outstanding ninjas of their own village to advance.

"I understand, Captain Zam," Lin Chuan nodded slightly. Let's take it one step at a time. There are still ten months until the Chunin Exams, so there's plenty of time.

"Remember to meet at the mission department tomorrow morning, there's a mission," Bai Yun told Lin Chuan after returning to Konoha that morning, before heading towards the Hokage Building.

In the Hokage's office, he stood in front of Hiruzen Sarutobi and reported his test results to Hiruzen Sarutobi.

"Lord Hokage, of the three graduating this time, only Chiba Rinkawa has qualified. Rinkawa already has the strength of a Chunin, so I will have him join us on missions to hone his skills..."

"Oh, really? That kid is still so sensible," Hiruzen Sarutobi stamped a large red "qualified" mark on Lin Chuan's ninja file, while the other two were all stamped "unqualified."

"Chuan is a good kid," Baiyun nodded gently in the morning, quite satisfied with the child. Not only was his swordsmanship good, but his tactical thinking was also good. He even knew how to use water clones to test him, use shuriken and steel wire to interfere with him, and take the opportunity to snatch the bell.

"Go, take good care of this child for me," Hiruzen Sarutobi waved his hand gently, signaling Shirayuki to leave early in the morning, as he also needed to attend to other official business.

……

Meanwhile, at the training ground where Class 7 was located, the person tied to the wooden stake this time was Sakura Haruno.

Because of Naruto and Sasuke's early training, both of them reached the strength of Chunin upon graduation. Ordinary Chunin couldn't defeat these two, and Naruto was even stronger than Sasuke.

In the early stages, Sasuke's chakra reserves were a weakness, and Naruto could overwhelm him with sheer numbers, making it impossible for Sasuke to outlast Naruto in a battle of attrition.

If Naruto had used Shadow Clones and Rasengan without regard for the cost, he could have overwhelmed a Special Jonin. That's how Naruto managed to snatch Kakashi's bell using sheer numbers.

Sasuke's strength is not bad either. If he could awaken his Sharingan, with the aid of the Sharingan, Sasuke could instantly become a Special Jonin. Kakashi is well aware of this, but Sasuke's chakra reserves are still a weakness.

Sakura Haruno is much weaker than Naruto and Sasuke, and is considered a mediocre genin. She only just realized that Naruto is actually so strong, and thought that Naruto had always been that truant underachiever.

"Sakura Haruno, the gap between you and them is too big," Kakashi said with a hint of helplessness in his dead fish eyes. There was no doubt about the bond between Naruto and Sasuke. In addition, Naruto liked Sakura, and Sasuke could also accept Sakura. The friendship between the three of them was pretty good, and they had all passed his test.

However, the difference in strength is too great. Naruto and Sasuke are strong enough to be promoted to special jonin at any time, while Sakura Haruno is only a genin, which makes things a bit difficult for him!

"Kakashi-sensei," Sakura cried as she was tied to the wooden stake. She thought she was pretty good, but it turned out she was the weakest one.

"Alright, I'll give you extra practice later. That's all for today. We'll start taking on missions tomorrow. Everyone needs to assemble at the mission headquarters..."

Kakashi gave an order, took out the "Make-Out Paradise" ninja tool from his pouch, turned around and left, ignoring Sakura who was still tied to the wooden stake. Naruto eventually untied her, but Sakura went after Sasuke and completely ignored Naruto.

Sakura's double standards hurt Naruto's young heart. He couldn't understand why Sakura didn't like him, even though he was so strong.
