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

"I understand," Sasuke said solemnly. Although he could reach the level of a Jonin after activating his Mangekyou Sharingan, if he didn't reveal his Mangekyou Sharingan and only used the three-tomoe Sharingan in battle, he would still only be a Special Jonin.

If the battle had continued, he might have actually revealed his trump card in the previous fight. He couldn't help but feel a chill of fear, since he would fight recklessly and activate the Kaleidoscope skill subconsciously, which was difficult for him to realize.

"What? That guy with the thick eyebrows has Jonin-level strength? Lin Chuan, you're not kidding, are you?" Haruno Sakura's mouth gaped open in an "O" shape, so surprised she could fit an egg in it. She never expected that the comedic guy was so strong.

"Believe it or not, I'm going to the restroom first," Lin Chuan said, taking his Chunin application form to the restroom. He didn't know how long the exam would take, so he decided to take care of his business first.

Seeing Lin Chuan leave, Naruto and his two companions entered the examination room first and witnessed a breathtaking scene. The room was filled with participating ninjas from various villages, each of them looking fierce and intimidating. They also met the other twelve Konoha 12, Shikamaru, Choji, Shino, Hinata, and others, a total of nine people.

When friends get together, they naturally start catching up on everyday things, and the nine of them began to chat, but were stopped by Yakushi Kabuto.

"Hey, you guys, you'd better be a little quieter. You're nine new recruits, right?" Kabuto Yakushi adjusted his glasses and rattled off information about the nine as if he knew them by heart: "You're nine new recruits who just graduated from the Ninja Academy, right? You're making a lot of noise and disturbing others. This isn't a vacation; this is an exam site..."

"Who are you? What are you saying that's really annoying?" Ino had a bad temper and was the first to not tolerate Yakushi Kabuto.

"Kabuto-senpai, it's been a long time..."

As soon as Lin Chuan entered the examination hall, he noticed the Konoha Twelve gathered together. Just as he was about to greet them, he saw Kabuto Yakushi's fake smile and blurted out Kabuto's name first.

"You two know each other?" Sakura reacted quickly, immediately grasping this detail and figuring out how the two knew each other.

"I know him. I don't really want to recall that period of my life," Lin Chuan said with a smile, staring at Yakushi Kabuto. He really liked this senior. He had just given him fifty kilograms of gold. Lin Chuan was already thanking the rich Kabuto for his generous donation.

"It's Kawa, long time no see," Kabuto Yakushi said, his heart sinking at the sight of Lin Kawa. He had a feeling that nothing good could come of meeting this guy, so he could only continue to remind him, "Instead of telling me my name, shouldn't we look around...?"

"What?" Naruto and his nine friends looked around and found that all the examinees in the examination room were staring at them with unfriendly eyes.

Everyone showed expressions of ferocity, disgust, and impatience, clearly annoyed by these noisy guys from Konoha.

"Oh, let me see who dares to be so arrogant in Konoha," Lin Chuan said, seemingly unconcerned by Kabuto's words.

But these roadside dogs dare to give them attitude in Konoha? Who do they think they are?

This is ultimately a place where strength speaks volumes. He glanced at all the outlying village ninjas present, his hand already gripping the hilt of his sword. He slowly drew the blade, his killing intent erupting instantly. His cold gaze fixed on everyone present, and he shouted at them, "What are you looking at? Want to die...?"

boom--

A surge of ultra-high pressure air burst forth from Lin Chuan's body, instantly melting the enhanced soldier's ration pill he had just consumed. This unleashed a chakra pressure several times stronger than his normal state, instantly suppressing all the examinees present, preventing them from raising their heads. They all lowered their center of gravity to resist the impact of the chakra pressure.

The same was true for the twelve young masters who were closer to Lin Chuan. They were closer to Lin Chuan and experienced a greater sense of chakra pressure. The weaker examinees had already collapsed to the ground, while only a few of the slightly stronger ones were still barely holding on.

Snap, snap, creak, creak—

Because of the burst of chakra, the wooden floor of the examination room began to crack inch by inch. Cracks appeared and spread outwards from the center of Lin Chuan's feet. The windows creaked under the weight. If no one stopped it, the pressure of the bursting chakra would destroy the classroom.

Suddenly, someone appeared behind Lin Chuan, gently placing a hand on Lin Chuan's shoulder. A serious expression appeared on his face, which was covered in hideous scars, and he whispered a reminder: "Junior, that's enough. It wouldn't be good to ruin the examination room..."

"Haha, sorry," Lin Chuan turned around at the sound and saw Ibiki Morino's terrifying scarred face. He quickly gave an awkward but polite smile: "Examiner, I'm sorry, I didn't control myself just now..."

"The younger generation these days is really getting better and better," Morino Ibiki muttered to herself as she saw Lin Chuan stop his chakra burst, before instantly leaving the classroom.

When Lin Chuan looked up again, the previous angry, cold, fierce, and impatient look in his eyes was completely gone, and he dared not look at the Twelve Little Strongmen again.

In just a moment, everyone was busy. Some were chatting with their teammates, some were lost in thought, and others were playing with the puppets in their hands. Everyone seemed to have become a very busy person.

"Looks like nobody wants to die," Lin Chuan said helplessly, shrugging as he looked at Yakushi Kabuto and asked with a smile, "Senior, what were you trying to say just now?"

"Huh? No, nothing?" Kabuto Yakushi's lips twitched. He hadn't expected that Lin Chuan would become so much stronger in just one year. The chakra pressure he had just unleashed must have reached the Jonin level. He really was a monster!

In fact, Lin Chuan didn't have the strength of a Jonin at all. The reason he was able to unleash such a strong chakra pressure was thanks to the enhanced version of the Soldier's Ration Pill, a secret medicine of the Akimichi clan that could instantly increase a ninja's chakra several times over.

The effects are only temporary, and the side effects are relatively minor, since it's a product that can be sold. As for the secret medicines that Choji ate, they are all deadly, and the Akimichi clan generally doesn't sell them.

The reason he bought this secret medicine was because it was an incredibly cool tool, and coupled with the amazing skill of releasing chakra pressure, how could he not learn it? That's why he used it just now.

Anyone can borrow someone else's power; one's status is self-imposed. After this show of force, any ninja lacking strength will naturally avoid him.

"Since it's nothing, where were we?" Lin Chuan looked innocently at everyone, giving his cute classmates a harmless smile.

"Tsk, what a monster," Shikamaru's lips twitched slightly as he stood up and complained helplessly. He hadn't expected this guy to be so strong. He was number one when he was a child and he's still number one now. Even the Uchiha clan members would probably be overshadowed.

"So this is your strength?" Sasuke clenched his fist excitedly. He had thought that Lin Chuan refused the challenge because he was really no match for him, but judging from the chakra pressure that had just erupted, this guy didn't seem to be no match at all. He clearly just didn't want to fight.

"Shikamaru, Shikamaru, is this really our classmate? Such terrifying chakra!" Ino was so frightened that she hid behind Shikamaru. She never expected that such a powerful person would emerge from their class. What kind of monster is this guy? Is it necessary for him to participate in the Chunin Exams? He could easily become a Jonin!

"So strong," Kiba Inuzuka said, holding Akamaru. He had just collapsed to the ground in fear, never expecting that such a monster would emerge from their generation.

Shino Aburame retracted his insects, which were startled and panicked, scurrying around inside his body.

"Wow, that's amazing." This was the first time Sakura Haruno had directly experienced the true strength of Lin Chuan, a fellow student of the same age. No wonder Naruto and Sasuke always said that they couldn't beat this monster.

Meanwhile, ninjas from other villages were also whispering amongst themselves...

"My goodness, this is terrifying! Are they here to participate in the Chunin Exams too?"

"Wow, Konoha has produced a monster this time? Or is it a hidden Jonin participating in the Chunin Exams? Is Konoha really that shameless?"

"I heard he's the genin from Konoha's current cohort who took the Chunin Exams alone..."

"With that kind of strength, he could probably take the Chunin Exams alone without any problem. Someone like that doesn't need teammates at all!"

"It's him? I didn't expect him to be so strong." Kankuro's hand holding the puppet trembled slightly. He hadn't expected the enemy he encountered in the alley to be so strong. He was really reckless to provoke him.

"These are Konoha's genin? Their strength is a bit over the top, isn't it?" Temari's fingers, gripping the fan, trembled uncontrollably. Konoha really is full of hidden talents; what kind of monsters are they?

"Interesting?" Gaara was not afraid at all after feeling the pressure of Lin Chuan's chakra. On the contrary, he became even more interested in Lin Chuan. He did not expect to encounter such an interesting enemy here.

He had experienced the chakra pressure of Shukaku. Compared to the chakra pressure of a tailed beast, what was the chakra pressure of a mere human?

"Hey, you from Konoha, didn't you collect information on a lot of people? Do you have any information on him?" Orochimaru stuck out his long tongue and licked his lips, pointing at Lin Chuan. He wanted information on Lin Chuan and suddenly became interested in the Water Release genius that Kabuto had mentioned.

"Yes, yes, Kawai, you don't mind, do you?" Kabuto lowered his head and pushed up his glasses. He recognized Orochimaru's voice, but before revealing information about Lin Chuan, he needed to symbolically obtain Lin Chuan's consent.

"Whatever you want," Lin Chuan said with a half-smile, looking at Yakushi Kabuto. Playing mind games with these big bosses is really a nerve-wracking experience!

"Then I'll tell you," Kabuto Yakushi said, taking out Lin Chuan's information card. He heard many people swallow hard. He then said, word by word, "Lin Chuan graduated first in his class from the Ninja Academy. After graduation, he was the only one who passed the test to lead a Jonin team..."

"His team leader was Hayato Shirakumo. He joined a team of three Jonin on his first mission, working together on an A-rank mission. Later, due to the increased difficulty of the missions, the A-rank missions were upgraded to S-rank. That's all the mission information we have..."

"One more thing, he participated in the Chunin Exams alone, without any teammates..."

"You've collected really detailed information, Senior Dou," Lin Chuan said with a smile, waving goodbye to everyone before sitting down in the last seat of the examination hall.

Upon seeing his arrival, the Sand Ninja in the last seat immediately stood up, indicating that she wanted to change seats, and fled as fast as she could, not daring to linger in front of Lin Chuan.

"S-rank? This guy completed an S-rank mission right after graduation?"

Everyone who heard this news was shocked and showed an expression of disbelief. What kind of madman was this guy? A genin doing an S-rank mission? Was he not afraid of death, or did he really have the strength?

There's no way around it, this resume and strength are just too terrifying. Do they really have any hope of participating in the Chunin Exams alongside such a master?

"Hehehe, interesting, interesting. It's been a long time since I've seen such a genius. Kabuto, you'd better keep a close eye on him." Orochimaru heard about Lin Chuan's resume and his dopamine levels surged. Another tempting body!

"Quiet down, you bunch of useless trash..."

Suddenly, Ibiki Morino appeared with his team of examiners. This time, however, the Sound Ninja did not attack Kabuto.

Because of Lin Chuan's intervention, there was no need to put on an act anymore. Moreover, he had already intimidated the group of ninjas from other villages. Everyone believed one thing: if they dared to look at him again, they would really die.

"Sorry to keep you waiting. I am Ibiki Morino, the examiner for the first round of the Chunin Exams." Ibiki Morino looked at Lin Chuan and warned him, "You in the last row, disrupting the exam order, this is your first warning. If you do it again, you will be eliminated immediately..."

"I'm reiterating the exam rules: fighting is not allowed without the examiner's permission. Even if the examiner allows it, actions that result in the death of another person are not permitted. Any idiots or good-for-nothings who dare to disobey the rules will be eliminated immediately..."

"Did you hear me clearly?" Seeing that everyone was silent, Ibiki Morino spoke again seriously: "Well then, let's begin the first exam of the Chunin Selection. Submit your application forms and take your number tags. Take your seats in order of these numbers..."

"Then, I will distribute the written test questionnaires. Please come forward one by one to receive a number and take your seat..."

As the candidates at the front went forward to receive their number plates, Lin Chuan naturally received his last.

When Naruto heard that there would be a written test, he was completely dumbfounded, because his academic performance was the worst.

After everyone was seated, the examiners began distributing the exam papers and announcing the exam rules. What followed was the process of candidates cheating and the examiners catching them cheating.

However, knowing that the first written test was a cheat code, Lin Chuan chose to hand in a blank paper and sat in the last row without writing anything, because he hadn't brought a pen at all.

"Why aren't you writing?" the examiner asked, puzzled, when he saw that Lin Chuan wasn't writing.

"I didn't bring a pen," Lin Chuan said bluntly, then slumped onto his desk and fell asleep. The side effects of the drug would kick in once they wore off, and he needed to catch up on his sleep, otherwise he might not be able to sleep for several days once he reached the Death Forest.

"Tch, all that talk about how strong he was, turns out he's just an idiot..."

Upon hearing that Lin Chuan hadn't brought a pen, many of those who had been startled earlier secretly chuckled, knowing that Lin Chuan would definitely fail the first exam.

Seeing Lin Chuan slacking off, Morino Ibiki sighed in exasperation. Lin Chuan's strength was more than enough to be a Chunin, let alone a Chunin. Some of the Chunin Examiners present might not even be able to beat Lin Chuan.
