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

"Is that Kawai?" Karin heard Lin Chuan's voice and finally mustered up her courage to look up. When she saw Lin Chuan's indifferent face, a smile appeared on her face.

Lin Chuan was the only gentle person she felt in Kusagakure. Only he would smile at her, care if she was hungry, and even bring her food to help her get through the most difficult and toughest winters.

"Tsk, girls in the ninja world are so naive. They'd give themselves to anyone for a piece of bread. Where can you find girls like that?" Lin Chuan noticed that Karin's cheeks were a little red, and he knew that Karin was mistaking him for Sasuke.

He didn't want this kind of attachment, because he couldn't take Karin with him. If Karin went to the real world, she would just become a cold corpse. He would also have to deal with this female corpse that had no identity record, which would be a very troublesome thing.

"I wondered who it was? Turns out I was assigned to this team," said Passerby A, who saw Lin Chuan and Karin as he came to the training ground and greeted them in an annoying tone.

All he knew was that his family had bribed the elder in charge of the Chunin Exams, and he was assigned to a team with logistical support, which increased his chances of passing the exams. It turned out that Karin, who could heal others, was in the team. Karin had a special constitution that allowed her to heal even the most severe injuries from a single bite.

"Kawa," Karin sensed the malicious chakra of her teammate and immediately hid behind Lin Chuan. In her perception, only Lin Chuan's chakra was not malicious, and she even felt a slight tremor.

That was all Lin Chuan's pretense, because Lin Chuan's persona is that he likes Karin. It would be strange if Karin didn't sense it!

whoosh-

Lin Chuan stared at his teammate's disgusting grin, then threw a kunai that grazed his face, drawing a line of blood. He muttered, "Kameta, if you dare bite her, I'll kill you..."

"You? Chuan? We're classmates! How dare you attack me for a piece of trash?" Kame touched the blood on his cheek, glared at Lin Chuan, and couldn't believe how Lin Chuan dared to do that.

"Alright, stop arguing," the team leader ninja quickly stopped the two from arguing, because both of them had given him money and were his big spenders. If they continued arguing, it would really put him in a difficult position.

"Go and prepare yourselves. We'll meet at the village entrance tomorrow and set off with the caravan to Konoha to participate in this year's Chunin Exams." Seeing that Kameta was still somewhat unconvinced, the Jonin in charge could only dismiss the two to prevent them from fighting.

"Hmph, Chuan, you just wait and see," Kame glared at Lin Chuan, gave Karin a vicious look, and then turned and left the training ground.

"Let's go, to my house, Karin," Lin Chuan said, pulling Karin away. Karin did not resist at all.

At this moment, Karin's head was spinning, and the only thing on her mind was the phrase "go to my house." Suddenly, she thought of the cohabitation that the adults were talking about. Was this how they were going to live together? Suddenly, she felt so happy.

That's impossible, of course. Karin sleeps on the sofa, and he sleeps on the bed. This house is only a temporary residence, and he never intended to come back.

After they finish the Chunin Exams, he will take advantage of the chaos to escape with Karin. If it weren't for Karin's storyline, he wouldn't have visited Kusagakure three times. Visiting Kusagakure feels more familiar than coming home.

While Karin was asleep, he quietly got up, put on his combat suit and ninja tool bag, and headed towards Kenta's pet shop.

That's right, this old man is still running a pet shop here. He hasn't been exposed at all after all these years. His purpose in coming here is to kill this old man so that there will be no evidence against him.

The reason is quite simple: wasn't he going to join Orochimaru's side?

So, they used the excuse of Root spies collecting talented ninja children to recruit Orochimaru's forces, who were associated with Root.

This was his first attempt. He had figured out that the Root spy, Kenta, had been tasked with gathering talented ninja children, and that he and Karin were among them.

Furthermore, given that Kenta was a Root spy, he could infiltrate Orochimaru as an informant. In any case, both Root and Orochimaru needed children with good ninja talent, and Orochimaru had no reason to kill a child who was offered up, especially after the deaths of the Sound Four and Kimimaro.

When he arrived at the pet store, he found that Kenta was even older than he had imagined. He had been an old man for twelve years and was now almost at the end of his life.

He really couldn't bring himself to bully an old man, so he decided to give the old man a quick death. When he died, the old man Jian Tai was stunned and didn't even realize why Lin Chuan was killing him. He didn't even know Lin Chuan before he died.

The Root spy is dead. Now it's up to him to decide what to do next. Hopefully, this path that took so long to explore will mislead Orochimaru!

The next day arrived quickly, and the group of twelve officially joined the caravan, embarking on their journey to the Chunin Exams in Konoha.

The Grass Ninja Village is located northwest of Konoha, roughly in the same direction as the Land of Rain. This time, the Grass Ninja Village sent three teams to participate in the competition. Originally, only two teams participated in the anime, but now Lin Chuan's team has joined the competition.

If Lin Chuan's guess is correct, one of the teams will be killed by Orochimaru, and Orochimaru will replace this Grass Ninja team to enter the second round of the Chunin Exams, the Forest of Death.

The thought of going to join that scheming snake made him sigh helplessly. After all, there was only one mad scientist in the ninja world who had created a low-end version of the Karma seal. He was really tempted by the technology of the cursed seal.

To prevent himself from dying in the ninja world and being unable to return to reality, he must learn forbidden techniques such as the Impure World Reincarnation, the Corpse Reincarnation, and the Cursed Seal.

Only by learning these forbidden techniques can he at least still have the possibility of doing sit-ups, or even doing sit-ups indefinitely. Without these forbidden techniques, if he dies, he dies; no one will revive this insignificant nobody.

Since Orochimaru is going to replace the genin team from Kusagakure in the second exam, it would be better if he were eliminated in the first exam, so that Orochimaru wouldn't kill him and replace him.

Three days passed quickly. The caravan traveled at a leisurely pace and soon arrived at Konoha Village. They then had to part ways with the caravan and head to the reception center that Konoha had arranged for the other ninja village examinees.

This time, he wasn't participating in the Chunin Exams as a Konoha ninja, and he wasn't friends with Naruto and the others, so he couldn't even talk to them and had no chance to show off. He could only stay obediently in the reception area and wait.

It really feels like a lifetime ago. Counting his previous time travels, he estimated it had been over twenty years since he last visited Konoha. Looking at these familiar streets, the familiar bustle, and the familiar neighbors, he really missed the three-color dumplings, grilled meat, and Ichiraku Ramen...

Time flies, and soon it was time for the Chunin Exams. They entered the exam hall early with their application cards. The plot was similar to the anime. Naruto was still the same loud and boastful underachiever, and his strength was still the same as in the anime. Sasuke had just awakened his two tomoe.

No one helped Sasuke get a power-up, no good teacher to guide him, and that brat wasted his time at the Ninja Academy. He still doesn't even have a Chunin, and he just got thrashed by Rock Lee.

He saw Shikamaru, who disliked trouble, Choji, who was greedy, Shino, who was silent, and the group of chattering girls again. He really missed the time when he was classmates with them, but unfortunately, none of them recognized him.

He saw Kabuto Yakushi again, whom he had killed before. Kabuto still had that fake smile on his face. It was a real pity that he couldn't kill him this time.

As the written test began, everyone started cheating, and Lin Chuan's team naturally followed suit. One arrogant guy was caught cheating, and they were eliminated without a trace, losing their qualification to participate in the second test.

"Kawa, you failed the exam," Karin said, still a little dejected. She caught up with Kawa as he left, apologizing and trying to comfort him. She had hoped that Kawa would pass the Chunin Exams and become a Chunin.

She has this kind of people-pleasing personality, which is caused by her environment. She is happy when she is needed, and she is even willing to give herself up.

"It's okay, we'll take the test again next time," Lin Chuan smiled and waved his hand dismissively, even though he had actually submitted a blank paper again.

If Karin and Kameta hadn't been caught cheating, he would have also chosen to abstain from the final tenth question, since he didn't want to face Orochimaru.

They returned to the reception area, but the Jonin leading the team wasn't there; he was probably out experiencing the vibrant world of Konoha again. Instead, he and Karin strolled around Konoha's commercial street.

With the Chunin Exams over, the other two teams of genin from Kusagakure passed the written exam. Next up was the second exam, the Forest of Death, where one of the Kusagakure teams was, without exception, lured out by Orochimaru and killed.

He received this news because the three Jonin leading the teams returned to the reception area with grave expressions and talked about the matter.

All three sensed that something was amiss in Konoha, as if a storm was brewing. They sat down together to discuss whether to cancel the Chunin Exams and return to Kusagakure ahead of schedule.

Lin Chuan knew that returning to Kusagakure was the most dangerous thing to do now, because Sunagakure had joined forces with Otogakure and were probably infiltrating Konoha right now. If they went out now, they would be walking right into a trap.

To avoid revealing their location, the Sand and Sound ninja would definitely try to kill them if they encountered them, which would only increase the unpredictability. Seeing that the three Jonin leading the team were hesitant, he couldn't help but suggest, "Captain, this is Konoha, the strongest of the Five Great Ninja Villages. If it's not safe here, I don't know where else is safe..."

"Yes, Chuan is right. If Konoha isn't safe, then other places are even less safe. I've decided to take my team and wait for the Chunin Exams to end," said Lin Chuan's captain, who was the first to declare that he wouldn't leave. He didn't know why, but he trusted Lin Chuan's words.

"All my genin subordinates are dead. If I go back now, I'll just get scolded. I might as well stay here a few more days..."

The leader of the Grass Ninja team, who was replaced by Orochimaru, also planned to stay here for a few more days.

"My squad has entered the Forest of Death. I don't know if we'll come back alive. We'll see how things go then," the last Jonin leading the squad sighed helplessly, deciding to wait and see how things unfolded and not wanting to be the first to stick his neck out.

Seeing that the three Jonin leading the team were not leaving, Lin Chuan breathed a sigh of relief. When the Konoha Collapse Plan began, he would immediately defect with Karin and head to the border area of ​​the Land of Rice Fields, the Land of Hot Springs, and the Land of Fire.

Because the Valley of the End is located at the border of the three kingdoms, he will wait here for Sasuke to defect, wait for the great battle of the Valley of the End to break out, and then take Karin to join Orochimaru.

……

A month later, the third round of the Chunin Exams was held as scheduled. These out-of-town examinees who had been eliminated were ignored like nobodys.

Today is the day of the third final round of the Chunin Exams. Lin Chuan did not go to the open-air venue to join the fun. Instead, he took Karin to the forest north of Konoha Village. The forest was just as he remembered. He planned to take advantage of the chaos in Konoha and rush out of Konoha with Karin.

"Kawa? Isn't today the final? What are we doing here?" Karin looked around at the surrounding woods; they were already close to the edge of Konoha Village.

"Get ready to run! A major battle is about to break out in Konoha!" Lin Chuan continued walking forward, carefully sensing his surroundings. He was surprised to find that even the Anbu were not there. It seemed that Konoha did not consider the genin from the outer villages a threat.

"How could a big battle have happened?" Karin wanted to ask something, but then she heard a series of booming sounds behind her.

Rumble, rumble—

Lin Chuan and his companion turned their heads and saw a three-headed serpent, more than ten stories high, breaking through the walls of Konoha and heading towards the village's reclaimed land, wantonly destroying the surrounding buildings and houses.

"Let's go, it's not safe here anymore." Lin Chuan saw that the Konoha Collapse Plan had begun, but he had no intention of watching the show. As for what the Jonin leading the team and Kameta were doing, that was none of his business.

If the two are still alive, and you can't find them when you go back, just assume they died in the Konoha Crush plan!

As Lin Chuan and his companion jumped into the forest, they gradually increased their speed and soon moved away from the chaos of Konoha. At this time, most of the Sand Ninja and Sound Ninja were causing trouble in Konoha Village, so the safest place was far away from Konoha.

After two days of continuous travel, Lin Chuan stopped to look at the map. They finally arrived at the border of the three countries and randomly chose a small town that was relatively close to the Valley of the End to stay in.

They removed their Grass Ninja headbands and disguised Karin's red hair. They needed to stay in the town for a month until Sasuke defected, and they had to keep a low profile to avoid being discovered by the Grass Ninja.

He used the stolen money to rent a room here. Karin didn't ask why and followed him obediently, rarely leaving the house. He was the one who went out to buy supplies.

Karin thought she could stay away from Kusagakure and live here with Rin for the rest of her life, so she settled down here without worry.

Girls in the ninja world are so innocent. Lin Chuan had countless opportunities to get Karin, but he never made a move because he was a despicable outsider who didn't belong to this world.

He could go without eating beef, and he could use any means necessary for power, even hacking his way from the gate of the stronghold to the back gate, his blade flashing and blood flowing like a river, hacking back and forth three times without blinking or his eyes getting dry.

However, he didn't want to deceive a little girl's feelings, especially since he also needed to use her. He was never stingy with those he could use, and Karin was no exception. If Karin could be used by him, then he would fulfill her wishes.

He took Karin away from Kusagakure. This wonderful encounter was just a beautiful memory he gave Karin after using her. Once he left the Naruto world, Karin would forget him anyway.

As for him, to put it bluntly, he's a middle-aged man in his thirties, his heart is already scarred and sealed with cement. People like him don't develop feelings.

Once he has successfully secured his allegiance to Orochimaru, he will no longer need Karin, and Karin will not develop feelings for him. He only needs to quietly knock Karin unconscious and take her away at the most crucial moment of the Konoha Collapse Plan, and he will not allow Karin to develop feelings for him.

The two of them then settled down in the small town, living a secluded life for a month, until one day the sky was dark and a light rain fell from the clouds. He stood under the eaves, gazing in the direction of the Valley of the End...
