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

"Give me some more time, I'm looking for a job," Lin Chuan sighed, his tone softening from initial impatience to helplessness. He bought the house a few years ago when business was booming; who could have imagined a black swan event, an unemployment crisis, and the collapse of the A-shares market...

The worst part is that housing prices have collapsed, causing him to lose money every day and he's already living beyond his means. He can't sell his houses either, and he's having a really tough time.

"Mr. Lin, we fully understand your difficulties, but overdue payments will incur additional penalty interest and negatively impact your credit score. If you are currently experiencing difficulties repaying, we can apply for an extension or renegotiate your repayment plan. Would that be suitable for you?"

"I already told you to give me some more time, just one month," Lin Chuan's tone softened from its initial harshness, and he continued, "Anyway, taking it back would just be a bad debt. House prices are dropping every day. If it's not paid off within a month, then you'll have to proceed with the process!"

Without waiting for the other party to say anything more, he hung up the phone.

He looked up at the door leading to the world of Naruto, his gaze intense.

In the past, he might have accepted the bank's "goodwill" and applied for an extension, only to continue struggling in an endless quagmire of debt.

But now, he had a better option. He slowly got up and walked towards the bedroom door. He hadn't brought anything with him, nor could he bring anything with him. Whether he could save this door and this house depended on this door.

A month was enough time. When I got back that night, it was still night, but a few minutes had passed and the cigarette butt was still warm, about five minutes.

If it's a five-minute time travel, you can have as much as you want for a month.

If it's five minutes a day, then a month would add up to more than twenty years, which is enough...

Lin Chuan's hand gripped the doorknob again. As the bedroom door opened, he was thinking about his obsession with Naruto. Strangely, the door leading to the bedroom was pitch black, and he couldn't see anything at all.

As expected, only this door was special. Faced with the pitch-black world inside, he did not enter immediately, but quickly closed the door, cleared his mind of the Naruto obsession, and thought about other things.

The moment he opened the bedroom door again, the darkness inside disappeared, revealing his familiar bedroom, exactly as it had been a week ago, without any change.

He finally figured out the mechanism behind the bedroom door's passage; it was indeed related to his obsession with Naruto, or perhaps to his thoughts. As long as he didn't think about Naruto, the passage door wouldn't appear.

He finally felt reassured. From now on, he would call this door the Naruto Door. After closing the door again, he thought about the Naruto storyline again, opened the bedroom door again, and the dark space inside the door reappeared.

He took out his phone to record and fixed it, pressed the timer and placed it on the ground. This time, without hesitation, he plunged into the door. He didn't close his eyes, but tried to open them wide, wanting to see the process of crossing over.

However, there is no process; the process of crossing over is like a black box. By the time he can see the surrounding scenery clearly, he has already crossed over.

This time, he was still a child. It was daytime on the other side, but nighttime on this side. But these weren't the strangest things. The strangest thing was that his birthplace was no longer the dilapidated wooden house he had been in before.

It was a wooden room. In the dim candlelight, he saw a woman with long white hair and eyes that were not the normal color he was familiar with, but snow-white.

Upon seeing those white eyes, he was momentarily stunned. He glanced at the woman's forehead and thankfully, she didn't have conjunctivitis or horns, but she did have white eye disease.

Suddenly, he snapped out of his daze, feeling a chill run down his spine from the woman's glare. He immediately turned and pushed open the wooden door to indicate that he was going home, saying, "Goodbye..."

"Who?" Kaguya Otsutsuki watched the small figure leave, feeling puzzled. Her child hadn't even been born yet, so how could there be a child here? Whose child was it?

No one could answer her questions, and the quiet cabin fell silent once more...

……

In the living room, after Lin Chuan returned from his time travel, he lay on the floor, panting heavily, his heart pounding as if it were about to jump out of his throat.

There's no way around it; one can understand a greedy samurai's first act.

But what the heck is the second Kaguya Otsutsuki?

He was facing a max-level boss right from the start, how was he supposed to play?

A little kid going to fight a big boss?

Stop joking! Luckily he ran fast, otherwise he would have been captured and trained as a White Zetsu and would be gone. The Naruto world is really dangerous.

However, this time travel also allowed him to verify some things, but he needs more control groups to draw conclusions, so he has to do it again.

This time, he wanted to know if the location of his travels was random, and whether his identity would always be that of a child.

There was also a timer, which had exceeded five minutes. He pressed pause to reset, and the timer would need to be restarted later. The phone video only showed him entering and leaving the bedroom door. After he entered, the bedroom door closed automatically, and where his body went remained a mystery.

The first time I traveled to the Naruto world, I stayed for at least half an hour, but in reality it only took five minutes.

The second time travel took less than a minute, but in reality it was still five minutes.

The third time travel...

……

"Bang, goodbye," Lin Chuan saw Orochimaru fiddling with test tubes in front of a dark basement. Seeing those cold, golden vertical pupils, he felt a chill run down his spine. He quickly pushed open the door and ran, even faster than when he faced Kaguya Otsutsuki last time.

Back in the living room, he was so frightened that his legs went weak and he couldn't stand up. He could only stop the timer, which showed that five minutes had passed, confirming that each time travel took five minutes.

He climbed over to the coffee table, picked up his notebook, and wrote it down. He just didn't know how many more days he stayed in the Naruto world would translate to how many minutes in reality; that remained to be verified.

And the travel locations are completely random?

Whether it was because he hadn't thought of the key plot points, or because his wild guesses were random, remains to be verified.

Is there also a state of being able to switch identities?

It's pretty much confirmed now; it's always a child.

The third time, because of Orochimaru, he almost missed the doorknob. Adults wouldn't have such a misperception; it could only happen to a child.

So, let's continue...

He drank some water, went to the bathroom, and then opened the bedroom door again. This time, his phone screen showed a picture of the Konoha Orphanage, with Yakushi Nonou and Kabuto in it.

He tried to imagine the Konoha orphanage, Yakushi Nonou's regrets, especially the orphanage's gate, and then began his journey through time.

……

boom--

"No, let's try again..."

boom--

"It's over," Lin Chuan sighed, lying helplessly on the ground, the cold floor preventing him from getting up.

He made a total of five crossings...

Carrying Neji's obsession, he was transported to the territory of a noble family in the Land of Fire for the first time, and was almost killed by samurai.

The second time, all I could think about was Naruto. I traveled back to the early days of Naruto and met Kaguya Otsutsuki, almost turning into a White Zetsu.

The third time, all he could think about was Naruto, and he ended up in Orochimaru's underground laboratory, almost becoming a test subject.

The fourth time he thought of the Konoha Orphanage, he ended up being transported to the Land of Rain during the Fourth Shinobi World War, where he nearly died on the chaotic battlefield.

The fifth time he thought of the classroom at the Konoha Ninja Academy, he ended up traveling to Kirigakure and was almost killed by the berserk Kaguya clan.

After five time travels, he resolved many of his questions and recorded them in his notebook. However, there were still a few questions that remained unanswered.
