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

"Very good, it seems you've calmed down," Lin Chuan nodded slightly, then asked the boss, "What was in the wooden crates the caravan took away a few days ago? Were they babies?"

"You?" The boss's pupils constricted sharply when he heard Lin Chuan's first question was so sensitive. He wanted to not answer and try to brush it off because he dared not offend those people. If word got out, his whole family would die.

Seeing that the boss remained silent, Lin Chuan picked up the kunai again, intending to cut his finger. The boss was genuinely afraid of Lin Chuan, fearing that Lin Chuan would cut his finger at the slightest provocation. He could only cry and snot stream down his face as he quickly recounted his story.

"Yes, they are all babies..." The boss kept sniffling, and finally breathed a sigh of relief after saying it.

"Which country are they a caravan from? What are they collecting so many babies for? When did they start collecting them?" Lin Chuan continued to press, trying to see if they were a caravan disguised as Konoha's. After all, collecting babies for experiments wouldn't do Konoha a good reputation if word got out.

"The caravans that come each time are different. I don't know what they want the babies for. They started collecting them three years ago. At first, they just bought abandoned babies from migrants outside the village who couldn't afford to raise them. But the caravans were getting more and more urgent, so people started stealing babies from the village..."

Lin Chuan noticed that each caravan was different, and thought to himself that it was indeed a fake caravan. Danzo was truly meticulous in his work. He then continued to ask, "Who else was involved in stealing the children?"

"There are many people I don't know about. After I couldn't buy any more babies, this place is just a transit point now. The black-clad thieves who steal children are all masked. They drop the children off here and leave. Once they have ten children, a caravan will come and take them away..."

"Tsk, looks like a pawn that can be discarded at any time," Lin Chuan knew he had already alerted the enemy, and this boss was no longer of any value.

So whatever you're going to do, do it now. Otherwise, once the spies at the root realize what's happening, they'll only become more vigilant and continue to question you, "You've been transferring the child for so long? Don't you know the background of these people?"

"I know, I know a little bit, I can roughly guess a bit," the boss swallowed hard, staring at Lin Chuan's blood-dripping kunai. He knew that if he didn't reveal any useful clues, he would only die, so he could only say, "Old man Kenta across the street, I feel he's very suspicious..."

"I've seen him many times, chatting and laughing with caravans carrying babies away. Sometimes he would even buy goods from them. I was dragged into this too. He took me to underground casinos to gamble. I often lost money there, so he would lend me money..."

"Later, I owed too much money and couldn't pay it back, so he introduced me to the baby trafficking business. At first, it was easy to buy babies, but later it became impossible to buy babies, so my place became a transit point. To this day, I still owe him a lot of money..."

"Looks like there's a big fish in the water," Lin Chuan said, instantly perking up. Of the five bases he had investigated, he only found this middle-aged boss selling babies; the other four remained silent.

However, the old man Kenta, who runs the shop across the street, is not included in the investigation, because he owns a pet shop and always buys goods from the Konoha caravan.

Sometimes he would buy dog ​​food from the Inuzuka family's caravan, and sometimes he would buy cat food from the Uchiha family's caravan. Each time, he would buy only a small amount, and he would only sell small cats and dogs. He did not continue to include them in his observation.

There was another reason that made him overlook the old man: the old man ran a pet shop, and furry things easily attracted children. In addition, the old man often gave children candy and snacks, and even he had eaten some.

He felt that the old man was a nice person, a grandfather who knew how to coax children, and he would give children some hamsters. He had received a hamster once, but he had managed to raise it to death.

Unexpectedly, he almost missed a big fish. That old guy was actually the most deeply hidden spy. On the surface, he was just an old man who ran a pet shop, playing with birds and teasing children with candy.

Behind the scenes, he actually lured honest people into gambling. Didn't the old man know that once you enter a casino, it's like falling into a deep abyss? He actually seduced people into making mistakes and leading them down the path of crime so that he could help Shimura Danzo commit adultery. It turns out they were in cahoots.

After getting the information he wanted, he sent the gambling addict on his way, washed off the bloodstains, and covered them up with a variety of mixed smells, such as the smell of barbecue, grilled meat, cigarettes, perfume, and soju from the night market.

After completely masking the smell of blood on his body, he took a stolen ninja tool pouch and went to the door of old man Kenta's pet shop. He knocked frantically, even looking around nervously, "Knock knock knock, knock knock knock, open the door, old man, open the door..."

"Who is it?" Old Man Jiantai opened the door sleepily, but he was actually already prepared to attack, his nerves on edge.

When he opened the door, he saw Lin Chuan standing outside, soaking wet and looking around nervously. He immediately understood what had happened, relaxed, and asked, "Xiao Chuan, did you steal something again, and try to hide here with me again...?"

"Stop talking nonsense, old man. I'll just hide it for a bit. This time it's a ninja tool bag. That ninja was drunk and passed out on the roadside. I don't know how much money is in the bag," Lin Chuan said as he entered the pet shop and gently shook the ninja tool bag in his hand.

The ninja tool pouch flashed in front of Kenta, obscuring his vision, while he suddenly pulled out a kunai from the pouch and stabbed it into Kenta's chest.

But the old man, Ke Jiantai, reacted quickly. Although he had no weapon, he immediately raised his hand to block the kunai, which only pierced his palm.

But Lin Chuan had a killer move. He opened his mouth and spat out three water needles, which rushed toward Jian Tai at an extremely fast speed, directly piercing through Jian Tai's palm and sinking into the old man's chest.

Whoosh whoosh—

"Huh?" Old Man Jiantai was shocked and groaned. He hadn't expected the water needle to be so penetrating.

Three water needles pierced his chest, then through the shelf behind him, before hitting the wall and losing momentum, leaving three needle holes in the wall. He was then knocked down onto the shelf by Lin Chuan.

Lin Chuan didn't have time to look at the little cuties. Taking advantage of the fact that Kenta's body had been pierced by the Water Release: Heavenly Cry, he pulled out four kunai from his ninja tool bag and pinned Kenta's limbs to the floor, severing the tendons in his hands and feet. Only then did he stand up, coldly look at Kenta, close the door, pull out a new kunai, and ask:

"Old man, you've been hiding well. How long have you been infiltrating Kusagakure? What's your mission?"

"What are you saying? Xiao Chuan? I don't understand," Old Man Jiantai said calmly on the surface, but his heart was in turmoil. He hadn't expected to be exposed, but he still wanted to tease Lin Chuan a bit more, since the other party looked like just a child.

"Stop pretending, you old fool. I need information about those babies," Lin Chuan continued to press, trying to get some information out of the old man. He actually just wanted to confirm the old man's identity and whether he was a spy for Root.

"Hehe, so it's those kids. It seems you've already been to the other side." Seeing that the shops across the street were dark, Old Man Jiantai knew that Lin Chuan must have asked the shopkeepers there. Otherwise, he wouldn't have been so sure that Lin Chuan was his online friend. He had miscalculated.

He actually lowered his guard because the other party was just a child, allowing the other party to suppress him unexpectedly. Otherwise, as an elite member of the Root, how could he possibly let a child get close to him?

"You lured him into gambling, causing him to rack up huge gambling debts, and you also introduced him to baby trafficking. As a spy for Root, you shouldn't have made such a basic mistake..."

"You actually know about Root?" The old man Kenta remained unfazed upon hearing about Root. Retired elders like them could only offer their last breath for Konoha, even at the cost of their lives. He continued, "Then you should know that I will not tell you anything about Lord Danzo and Root..."

"Is it a seal?" Lin Chuan knew about the technique to eradicate the tongue-twisting curse, but he didn't say it aloud. Instead, he pressed, "Is there anything here that can prove your identity?"

"You didn't come here for those children?" Old Man Jiantai thought Lin Chuan was a good kid who couldn't stand seeing those children being trafficked, so he came to him to get his children back. He didn't expect it was for something else.

"Do you think I can bring those children back? I need something to convince the higher-ups of the Grass Ninja Village to help me save them," Lin Chuan said, pretending to be weak and helpless, as if he could only ask for outside help. At this moment, he was like a helpless child.

And that was indeed the case. He couldn't have found the children on his own, nor did he intend to. Finding the children was merely misleading the spy with false information; his purpose remained unchanged from beginning to end.

"It's impossible. You can't persuade the higher-ups of Kusagakure to save the child. Even if you could, they wouldn't dare to save the child or be an enemy of Konoha," the old man Kenta shook his head and sighed. As a ninja who grew up in Root, he knew too well the darkness of Konoha. It was rare for him to say a few more words to this child.

"Never mind that, old man. I need to persuade the higher-ups of the Grass Ninja Village." Lin Chuan stared intently at the old man. He realized that the man was already prepared to die. After all, being captured alive on the spot meant he was doomed. All Root ninjas were aware of this.

"Since you want evidence, there's a scroll from Root that they sent me to collect information on children under the wooden floor of the cat cage over there. Take it and hand it over to the higher-ups in Kusagakure, and see if they dare to demand an explanation from Konoha..."

Jian Tai looked at Lin Chuan with confidence, certain that Lin Chuan would not succeed; this was the difference between a large country and a small country.

Even if the higher-ups of Kusagakure see the mission scroll, they will only deal with Lin Chuan who raised the issue, rather than questioning Konoha about why they stole the child. It's simpler to deal with Lin Chuan, and the higher-ups of Kusagakure know which option is more advantageous to them.

"You're lying. Root doesn't leave any evidence when issuing missions. Even if there were mission scrolls, you would destroy them the moment you received them," Lin Chuan didn't believe this old man was trying to take them all down with him.

"Hahaha, you brat, you're really clever, but it's too late," Old Man Jiantai chuckled, his eyes suddenly turning cold as he sneered, "You're too clever, and you know too much about the roots. I can't let you live..."

Sizzle, sizzle—

"Explosive tags?" Lin Chuan heard a hissing sound from the wall and floor, and saw explosive tags appearing. It turned out that a dog had activated the explosive tags. He cursed inwardly.

Before leaving the pet store, he glanced around and suddenly noticed the bird hanging by the door. This old man took the bird with him everywhere he went—eating, drinking tea, going to the toilet, sleeping. This little bird must be special. He jumped up, grabbed the birdcage, and immediately disappeared from the pet store.

Seeing Lin Chuan reach for the birdcage, Old Man Jiantai's pupils constricted. He tried to stop him, but it was too late. The explosive tag instantly burned out, creating a series of booming explosions that sent the entire pet shop flying into the sky.

Having retrieved the birdcage, Lin Chuan had already moved away from the street where the explosion occurred. He returned to a safe house he had rented through theft during this time, put down the chirping little bird, and with just a glance, his undisguised killing intent oppressed the bird. The bird was immediately intimidated and shut its mouth, no longer making a sound.

"Tsk, I'm still too green to deal with these spies," Lin Chuan began to check his body for injuries. He didn't expect that even though he had already suppressed his opponent, the opponent was still trying to lure him away, and in the end, he even wanted to die together with him.

Even the misleading information he set up didn't work on the other side. It's true that you can't underestimate anyone, even a retired old guy from the root can make him fail.

After checking that he was not injured, he immediately looked at the bird and the birdcage. The rule of the Dark Division is that the dead should not be left with their bodies. The Root Division naturally has the same rule. Because of the existence of the Mountain Clan, the corpses cannot be obtained by the enemy to prevent the enemy from having the secret technique to see the memories.

Without corpses, there is no intelligence, especially for Root members who are tools of the ninja, without past or future, without names, without emotions, and only have orders. After death, they leave nothing behind except their code names for serving in Root, which record that they once existed.

How could a mole like him treat a bird like a treasure? He reached out and grabbed the bird out of the cage, only to find that the bird had a leg band with words on it, which looked like the character "休" (xiū, meaning "rest" or "retire").

Does this word have any special meaning to that old guy?

He suddenly remembered that when the old man teased the bird, it would make a "whooshing" sound. He then checked the bird over and over again and found that it was just an ordinary little bird with nothing special about it. He then checked the cage again and found that it was still an ordinary cage with nothing special about it.

He examined the bird and its cage four or five times before finally understanding their meaning: "A caged bird? Heh..."

The meaning of "caged bird" is quite simple: falling into Danzo's hands and becoming his tool ninja is just like how the life and death of the Hyuga branch family members are controlled by the Hyuga main family. The old man is comparing himself to a caged bird!

The character "休" on the bird's leg ring is likely the code name of the old man Jian Tai. The old man probably wanted to express that he was like a caged bird, and even after retirement, he would still work for the root until he died.

His code name at the Root was Chuan, so he guessed that Xiu was the old man's code name, but he couldn't be sure yet and needed to verify it again.

He had already obtained important clues during this time travel, so there was no need for him to stay any longer. After all, he had already alerted the enemy, and the Root would definitely investigate the cause of Kenta's death. He didn't want to get involved in what followed.

This journey through time has come to an end. He spent another six years in Kusagakure. Time really flies.

Besides obtaining important clues, this time travel was not wasted. Because of the existence of the Hidden Mist Technique, he boldly practiced all the ninjutsu he had just learned before, making up for his previous lack of proficiency.

For example, the proficiency of advanced ninjutsu such as the Secret Sword Moon Shadow, Konoha Style Sword Technique Willow, Naraku Sight Technique, Hand Sword Shadow Clone Technique, and Water Severing Wave, which I just learned, has all been improved in these six years.
