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

"The third preliminary round of the Chunin Exams begins. The first match is between Lin Chuan and Yakushi Kabuto," Gekko Hayate announced, glancing at the draw order on the big screen. He then continued, "The other participants, please proceed to the stands..."

"Hmm?" Lin Chuan looked up at Orochimaru as he heard the battle arrangement. He only saw Orochimaru's meaningful smile, then turned his head and saw Kabuto Yakushi with a half-smile. He instantly understood what the two of them were up to.

"I see," he thought, turning around and standing there, facing Yakushi Kabuto who was gently adjusting his glasses. He couldn't help but laugh. "Then I'll play along with these two."

At the same time, he looked at Baiyun Zaojian in the audience and nodded slightly to Baiyun Zaojian to signal him to get ready.

Seeing Lin Chuan looking over, Bai Yun also began his own actions that morning, searching for trustworthy Jonin to cooperate with Lin Chuan's plan. He needed at least two teammates.

He had planned to look for Kakashi, but Kakashi had been beaten up by Kushina Uzumaki, and his face was swollen. He was currently being treated in the infirmary, so he could only look to Asuma and Guy, hoping that the two of them could cooperate with him.

Back on the field, Lin Chuan slowly gripped the hilt of his sword. There was no water here, and if he used Water Clone and Instantaneous Movement Technique continuously, he wouldn't be able to hold out for long; he could only perform a brief feint.

"Secret Sword, Moon Shadow!" The moment Moonlight Gale shouted "Start!", Lin Chuan moved at lightning speed, transforming into dozens of phantoms that stood around Kabuto Yakushi.

"This is... Moon Shadow?" Moonlight Gale only knew this move, but he didn't expect Lin Chuan to know it too. He'd learned this sword technique at such a young age; he was truly impressive. He was about to exclaim in admiration when he couldn't help but cough, "Cough cough cough, cough cough cough..."

"Kawa? Where is your real body?" Yakushi Kabuto silently took out a kunai and looked around. Suddenly, he raised the kunai to block, and a spark flew out of the kunai. Then, Lin Chuan's real body disappeared again.

Ding ding ding, ding ding ding—

Each phantom could unleash a sword-drawing attack, but all of them were dodged by Kabuto Yakushi or blocked by kunai, making it impossible for him to get close.

Lin Chuan could only increase the frequency of his attacks, even having multiple phantoms attack simultaneously. The sword light danced like a series of knife flowers, and finally, he managed to cut Yakushi Kabuto's arm, drawing out a stream of scalding blood. He had done his best.

He knew he was no match for Kabuto Yakushi. Fighting an enemy with such keen senses, the opponent would never reveal a weakness. He couldn't defeat Kabuto in his current state, and if he continued to wear him down, he would run out of chakra.

Don't be fooled by the large amount of chakra in two A-rank ninjutsu. They can only be converted into a D-rank Body Flicker Technique and used more than twenty times, or into a C-rank Water Clone Technique and used more than ten times. Moreover, we are currently in a waterless environment.

boom--

When he injured Kabuto's arm, he deliberately created an opening in the illusion, allowing Kabuto to kick him away, sending him crashing heavily into the wall. The impact caused his stomach to churn and his internal organs to shift. He scrambled to his feet, not even bothering to wipe the vomit from his mouth, and hurriedly raised his hands, shouting, "I surrender..."

Just as he shouted that he was surrendering, Kabuto Yakushi held a kunai to his neck, almost slashing him.

"What the hell, Lin Chuan? Aren't you supposed to be strong? Why are you giving up?" Naruto shouted loudly when he heard Lin Chuan admit defeat. This hot-blooded idiot didn't want to see his good friend give up without giving it his all.

"Idiot, can't you see that Kabuto is strong? Lin Chuan is no match for Kabuto," Sasuke explained. He could tell from the battle by the river that Lin Chuan was no match for Kabuto, so naturally he couldn't beat Kabuto here either.

Unexpectedly, Kabuto is so strong. Even Lin Chuan is no match for Kabuto. They misjudged him from the beginning. This person clearly has such strong strength, so why has he failed the Chunin Exams seven times in a row?

What is this person hiding? What is their purpose? What is their relationship with Lin Chuan? Are these two truly mortal enemies?

"Heh heh heh? Chuan? Admitting defeat?" Orochimaru didn't believe Lin Chuan would lose, but why was Lin Chuan hiding his strength? What was his purpose? These questions puzzled him as well.

Actually, everyone was wrong. Lin Chuan's chakra reserves are currently insufficient, so he really can't defeat Kabuto Yakushi, whom even Kakashi couldn't defeat. Even Kabuto in his early stages, whom Kakashi acknowledged, was no weakling.

He slowly raised his hands, leaving Kabuto's blade. With so many people watching, he didn't believe Kabuto would dare to strike. After all, he had a Jonin leading the team who would stop Kabuto from killing him. If Kabuto did kill him, he would be killed by Hayato Haku. That was the deterrent power of a Jonin.

"Senior Kabuto, you won," Lin Chuan said with a smile, looking at Gekko Hayate and gesturing for him not to announce the result of the match.

"Chuan? You're really lucky," Kabuto Yakushi breathed a barely perceptible sigh of relief when he heard Lin Chuan admit defeat. Lin Chuan's surrender was his only chance of survival.

Because he couldn't possibly kill Konoha's genius ninja in front of so many Jonin, and he had to carry out Orochimaru's orders, he was in a life-or-death predicament. Only by making this smart man admit defeat could he leave this place alive and complete Orochimaru's mission.

"Is that so? But does Kabuto-senpai think he can leave just because he won?" Lin Chuan smiled and looked at his team leader, Jonin Shirokumo Hayato.

"What do you mean?" Just as Kabuto was about to use the Body Flicker Technique to leave, a kunai was placed against his neck, along with Asuma's chakra blade. He was surrounded by three Jonin at the same time.

"Yakushi Kabuto? Someone reported you as a spy from an enemy country. Come with us." Bai Yun nodded slightly to Lin Chuan in the morning. He was able to help Lin Chuan capture Yakushi Kabuto because Lin Chuan had provided evidence that Yakushi Kabuto was a spy.

"Kawa? Is that you?" Kabuto seemed to understand something, looked up with an incredulous expression at Kawa, who was still putting on an innocent face.

"Senior Kabuto, please don't wrong an innocent person," Lin Chuan said with a helpless shrug. He was now near the exit, the only way to take away Kabuto.

"Hehehe, I see." Orochimaru saw that Kabuto Yakushi was surrounded by Konoha Jonin, but he had no intention of taking action. After all, there were plenty of ways to rescue Kabuto, so there was no need to rush.

"Let's go," Asuma said, taking out a sealing talisman and sticking it to Kabuto's chest. The talisman instantly spread out several incomprehensible black runes, binding Kabuto's entire body and sealing his chakra.

Sealing talismans are a type of sealing technique. They are sealing techniques inscribed on talisman paper, allowing ninjas who cannot use sealing techniques to perform them.

Thump, thump, thump—

Kabuto Yakushi realized that his chakra was sealed and he couldn't use any of it. He could only look up at Orochimaru in the crowd in the stands. He knew that Orochimaru would come to save him because he still had some use to him.

Next, he will face interrogation by the Konoha ninja. Hopefully, Orochimaru can rescue him before the Anbu interrogate him, otherwise, he has no idea how many secrets he might reveal...

puff-

Kabuto Yakushi, who was pondering how to withstand the torture in the interrogation department, stared in astonishment at the kunai in his chest. The entire blade of the kunai was inserted into his chest, piercing his beating heart. He could feel his life slipping away.

Lin Chuan's sudden attack stunned everyone present, including Orochimaru...

Lin Chuan's hand was still on the kunai. He knew that Kabuto Yakushi's medical ninjutsu was very powerful. He instantly twisted the kunai with force, grabbed Kabuto's shoulder with one hand, brought it close to Kabuto's ear, and suddenly exerted force with the hand holding the kunai, directly crushing Kabuto's entire heart.

Then, whispering in Kabuto's ear, "Kabuto-senpai, do you know? During my time with Root, you kept me up every night. I... wanted... you... dead... so badly..."

"Chuan?" Blood flowed from Yakushi Kabuto's mouth. He reached out and grabbed the kunai, trying to stop Lin Chuan from turning his palm, but he couldn't use his chakra, and with his heart pierced, he could only let Lin Chuan tear his heart apart.

He suddenly noticed Lin Chuan looking at his arm, and he looked at his arm as well, discovering that it was a wound from the battle just now, and instantly realized what had happened.

It turned out that Lin Chuan's goal from beginning to end was to kill him, which was surprisingly consistent with his own goal. He said they were the same kind of people, and he was absolutely right.

Lin Chuan knew he couldn't beat him and that he was hiding his strength, so he deliberately set a trap, getting Orochimaru to order him to kill Lin Chuan. Then, during the battle, Lin Chuan deliberately injured himself, his purpose being to confirm whether he was a shadow clone, because no matter what kind of clone it was, it would dissipate when attacked.

After confirming that the person fighting was the real deal, he ordered the Jonin to arrest him under the guise of a spy, and even used three elite Jonin at once.

Facing three elite Jonin, so many Konoha Jonin, and even the Third Hokage present, there was no way he could escape.

Given his status as a spy from an enemy country and a Jonin-level expert, even the three Jonin dared not be careless. They even used a sealing talisman to seal his chakra, making it impossible for him to use his chakra and thus unable to resist.

Then, in a way that no one expected, Lin Chuan killed himself with a single stroke; this was Lin Chuan's true purpose.

Kabuto felt his vision blurring. He looked up at Orochimaru in the stands and was surprised that Lin Chuan had managed to scheme against even Orochimaru and his own killing intent. What a deep scheme!

I bet Lin Chuan wanted to kill me the moment he saw me at the root. Why? Why does Lin Chuan hate me so much, to the point of wanting to kill me, and yet he's so patient, holding back until now before making his move?

"Chuan? Give me a reason to kill him?" Bai Yun had believed Lin Chuan earlier because Lin Chuan was his student, but he wouldn't blindly trust Lin Chuan; Lin Chuan had to convince him first.

"Ms. Morning, it's better to kill such a dangerous spy. You can get information from the dead..."

This was Lin Chuan's explanation. Whether Bai Yunzaojian believed it or not, he believed it anyway and looked at Bai Yunzaojian very seriously.

It wasn't that he looked down on Konoha, but Konoha had been infiltrated by Orochimaru and turned into a sieve. Let alone a living person, the people of Konoha probably wouldn't even be able to keep a single corpse. So it would be better to kill Kabuto.

From the moment he decided to revive Kushina Uzumaki, the Chunin Exams were no longer a game, but a life-or-death struggle. If he wanted to survive to the end, he had to kill Kabuto Yakushi, otherwise he would be the one to die.

As a modern person who doesn't eat beef, this question is not difficult to answer at all, so Kabuto died, severing Orochimaru's arm first.

"Take him to the interrogation department and let the Yamanaka clan handle him," Hiruzen Sarutobi said, glancing at Kabuto Yakushi's corpse, then at Rin, before finally waving his hand to have the Anbu take Kabuto's body away.

He wondered if it was because he was getting old, but he always felt that Lin Chuan was acting strangely. Since the second Chunin Exam, there had been too many unexpected events, and Orochimaru, his former genius disciple, had interfered, leaving him no time to pay attention to this child. Now he finally noticed something was wrong.

However, since it's said that Kabuto Yakushi is a spy, we just need to wait for the interrogation department's results. If Kabuto Yakushi isn't a spy, then Lin Chuan won't be able to escape either. He will reassess Lin Chuan's mental state to see if he can be a qualified ninja.

"Phew, it's morning. Nothing much, I'll be going now." Asma glanced at Lin Chuan one last time, not paying any attention to Lin Chuan's actions. They helped because of Bai Yun's favor in the morning, not because of a child's order.

And this kid has been to the root, he's really a pitiful kid. After going to that kind of place, none of them are normal people, so it's not surprising that he would suddenly kill someone.

"I'm leaving too," Kai said, having also departed. He truly hadn't expected Lin Chuan to suddenly turn violent and kill someone. These young people these days are really hard to understand!

However, it is certain that these two are teammates in Root, so it is normal for them to fight each other. I heard that Root is a very dark place, and Danzo said it himself. I didn't expect it to be so dark that it could drive a child crazy.

"Hehehe, Chuan, you actually killed Kabuto? Is this your purpose?" Orochimaru subconsciously licked his lips. When he saw Lin Chuan make his move, his eyes twitched, and he thought to himself that he was ruthless enough.

But it was too late for him to stop it. Even if he could, he wouldn't want to. Kabuto's death couldn't interrupt his plan to watch Sasuke fight. He simply let a small white snake slip out from his trouser leg and chased after Kabuto's corpse unnoticed.

Kabuto did manage to uncover some value, but it was meaningless. After all, he had said they were once teammates in Root. Danzo's Root was a place that specialized in training a bunch of killing machines; it would be normal for them not to go insane.

He hoped Lin Chuan was just a crazy kid, as that would be easier to deal with. If he was an old monster, it would be difficult. He hadn't figured out what Lin Chuan's purpose was in hiding his strength in Konoha.

"Kill, murder..."

Many candidates were shocked to see Kabuto win and then die, and remained speechless for a long time.

Not to mention the examinees, even the other Jonin leading the teams were dumbfounded. After all, even Orochimaru was dumbfounded. He didn't expect Lin Chuan to admit defeat and then suddenly kill someone, and the one he killed was his opponent. It was simply absurd.

Is this really Konoha, one of the five great ninja villages?

They seemed even more ruthless than the madmen of Kirigakure.

The world had turned upside down to the point that they no longer recognized it, and everyone was caught in a state of self-doubt.
