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

"Phew, finally it's over." Lin Chuan didn't dare to be careless. He took his knife and entered the blown-up wooden house. He quickly found Black Mountain Second Brother, the bandit leader who had been drinking and playing with women in the hall just now.

He breathed a sigh of relief as the bandit leader lay dead on a pile of shards, his eyes wide open in disbelief. He then picked up his dagger and chopped off the leader's head to prevent him from reviving. After that, he attached an explosive tag to his body and blew the bandit leader's corpse to pieces.

He continued to charge at the group of bandits who had been awakened by the noise, along with seven or eight others who were still carrying knives. The others had already fled in panic, and he didn't bother to chase after them.

Ordinary bandits would be slaughtered by ninjas in a one-sided massacre. These bandits, who had been drained by wine and women, could not keep up with his speed. Only when they could not avoid the siege would he use the Body Flicker Technique to escape, and then slit the throat of another bandit.

It took him a lot of effort to deal with these bandits, after all, he was just a child. He pressed the blade against the ground, panting heavily. His chakra was almost depleted, his adrenaline was waning, and he was completely exhausted.

If it weren't for that water dragon bullet, he would still have chakra. He quickly ate a soldier's ration pill to restore his chakra before getting up and looking in the direction of Yamanaka Fu and Aburame Torune.

The two bandit leaders over there are quite close together. If someone can't beat them, the two will definitely help each other. He could tell what Shan Zhongfeng meant when he was assigning targets to the bandit leaders. Sure enough, taking the root is true love.

Only after the shouts of battle subsided did he slowly walk towards the area, where he saw a similarly dilapidated wooden hut. It seemed that they had used plenty of explosive tags, otherwise it wouldn't have been so easy.

"Did you handle things over there?" Yamanaka Fu helped Aburame Torune up. The man had been slashed by a scalpel because he had exposed his whereabouts and alerted the wandering samurai. The wound wasn't too deep.

"It's resolved," Lin Chuan nodded gently, looking at the burning and collapsed wooden house, the corpses scattered all over the ground, and a group of weeping women.

"Clap clap clap, you did a great job!" Kabuto Yakushi jumped out of the shadows as he saw the three of them gather together, and clapped his hands lightly twice to encourage them.

"Have we completed our mission?" Aburame Torune asked Yakushi Kabuto, his arm still bleeding.

"Not yet? Aren't there still some survivors?" Yakushi Kabuto's masked face looked at the group of women behind the three of them, who were terrified and squatting on the ground, crying.

"You? Those are all innocent people," Aburame Torune naturally saw those women. The bandits had destroyed all their homes, and those people were now homeless. They were all pitiful people.

"Innocent? Heh," Kabuto Yakushi sneered when he heard "innocent" and remained silent, waiting to see what the three of them would do.

"Captain, I've taken care of it." Lin Chuan's short knife was still dripping blood. He tried his best to control his trembling hands and stood silently behind Yakushi Kabuto, looking at Yamanaka Fu and Aburame Torune with the same indifference.

He knew better than anyone what the Roots were. In the Roots, there were only orders, no self. Abandon the past, abandon the future, obey orders. Two months was enough time for him to adjust himself and adapt to his new life in the Roots.

"Chuan, you, you guys?" Aburame Torune was shocked again. She never expected that Lin Chuan, who was even younger than them, would be so ruthless, leaving no one behind.

"Take the root, this is the root," Yamanaka Fu looked at Lin Chuan. He realized that he still preferred having the kind-hearted Take the root as a teammate compared to Lin Chuan, and could only continue to comfort his companion: "Take the root, he is indeed better than you at adapting to the root..."

"I understand," Aburame Torune had also heard Shino mention Hayakawa. She thought it was unfortunate that Hayakawa had joined Root like herself, since Hayakawa's life was so fulfilling, with a family, parents, and friends like Shino.

However, I didn't expect that the other party would adapt to the root faster than I did. I was really worried for Shino's friend for nothing.

"You're very good. I went to check, and it's indeed resolved." Kabuto Yakushi nodded slightly with satisfaction. He had come from Lin Chuan's side and witnessed Lin Chuan's carnage. The bandit leader was even blown to pieces. He was really ruthless.

As for the women who had been abducted by the bandit leader, they drowned in the shattered house after being hit by that water cannonball.

Lin Chuan knew those women were innocent, but he had no choice. If they didn't die, he would be the one to die. Between someone else dying and himself dying, as a modern person with flexible moral standards, was there even a choice? It was definitely someone else who would die.

At worst, he'll stop being a good person and stop eating beef from now on.

It's hard enough to be a good person in modern times, let alone in a ninja world. Don't make it harder for him; he doesn't want to be a good person here. He's not a good person.

If it weren't for that water cannonball, Lin Chuan would have been like Yamanaka Fu and Aburame Torune, using a knife to deal with those innocent women!

"You all did a great job," Kabuto Yakushi said. After seeing that Fu and Yamanaka had finished dealing with the remaining prisoners, he took notes on the three men's performance. Then, he took out the sealing scroll and went to the bandits' warehouse, loaded all the useful supplies, and the four of them left the ruined mountain stronghold.

The four did not continue their journey that night. They came to a relatively secluded jungle and rested quietly in the darkness, while some of them silently licked their wounds.

Aburame Tori's arm has been bandaged up, thanks to his partner Yamanaka Fu. Now it's their turn to keep watch. After they keep watch until dawn, it will be Rin and Yakushi Kabuto's turn to keep watch.

After resting for a while, and with daylight breaking, the four continued along the border of the Land of Hot Water, heading towards the Land of Rice Fields.

The three of them used all the bandits they encountered along the way as practice. These bandits were like weeds; once a batch was killed, they would reappear after a while. This was especially true in the chaotic country of Tang, which had been invaded by a cult.

Later on, they saw that they dealt with the bandits all by themselves, and without exception, no one survived in the mountain stronghold.

The journey and killing of bandits during this period had left Lin Chuan feeling numb from wielding his sword so much that his short knife had become dull and chipped in many places.

He couldn't remember exactly how many people had died. When there were only one or two, he would still check what the person looked like. But when there were dozens, hundreds, or thousands...

He could no longer remember who the first person to die by his blade was, or what they looked like...

Seeing that Lin Chuan and the other two were in similar condition, Kabuto Yakushi smiled and led them into the Land of Rice Fields, no longer lingering in the Land of Hot Springs.

This time, he destroyed more than a dozen mountain strongholds and collected a large amount of useful and useless resources. He will then give them to Orochimaru's newly established Otogakure and let the Otogakure ninjas deal with them. These resources will be enough for Otogakure to develop for a period of time.

After the four entered the Land of Rice Fields, Kabuto led the three to a nearby hot spring town and instructed them, "You rest here for now, I'll go hand over the mission details..."

"Yes, Captain," the three watched as Kabuto Yakushi turned and left, without asking any further questions.

Danzo handed the scroll to Yakushi Kabuto, thinking that since he didn't want them to know, it was better for him not to know either.

The three then went into the hot spring town and parted ways, agreeing on a signal to meet again.

Yamanaka Fu and Aburame Torune teamed up and disappeared together at the end of the hot spring town, not wanting to stay with Hayashi Kawa.

Lin Chuan didn't care about the distance between the two. He took clothes and pants from a clothesline, put them on, and put away his ANBU equipment and ninja tool bag. He only kept a kunai in his pocket for self-defense, and put the rest in his bundle before stepping into the hot spring town.

……

Meanwhile, Kabuto Yakushi, alone with the sealing scroll, arrived at Otogakure in the Land of Rice Fields, at Orochimaru's underground laboratory.

He smiled and glanced at the little tail behind him. It was a Jonin ANBU sent by Danzo to protect Lin Chuan and the other two. They wanted to follow him to Orochimaru's lair, but he managed to shake them off.

Upon entering Orochimaru's underground laboratory, he encountered Orochimaru conducting research and took out the sealing scroll that Danzo had given him.

"Lord Orochimaru, this is the sealing scroll given by Danzo," Kabuto Yakushi said, immediately kneeling on one knee to hand over the scroll upon seeing Orochimaru.

"Hehehe, Kabuto, you've worked hard," Orochimaru turned to look at Kabuto, his golden vertical pupils somewhat eerie, his face still so pale and bloodless.

"It's no trouble at all, Lord Orochimaru," Kabuto Yakushi said after returning from his undercover mission and seeing Lord Orochimaru again. He had a lot of information he wanted to share with Orochimaru.

Orochimaru took the sealing scroll, saw the message left by Danzo, and suddenly laughed, "Hehehe, Danzo is getting a little anxious..."

"Lord Orochimaru, the three children who came with me this time are all children with very good ninja talent. Should we keep them?" Kabuto Yakushi was very envious of the talents of Lin Chuan and his two companions.

One possesses the family secret technique of the Mountain Clan, another possesses the poisonous insect secret technique of the Aburame Clan, and the third possesses considerable talent in water escape.

"No need, my research is almost complete. I can have as many geniuses as I want then," Orochimaru said with a smile, licking his lips. Once his cursed seal research is successful, even ordinary ninjas will be able to use Sage Chakra.

Making ordinary ninjas use Sage Chakra to increase their strength, elevating Chunin to Jonin, and Jonin to Kage level—isn't that genius research?

"Yes, Lord Orochimaru," Kabuto Yakushi replied, abandoning his plan to kidnap Lin Chuan and the other two. After all, if he kidnapped them, he wouldn't be able to go back.

"This is what Danzo wants. Give this scroll to him." Orochimaru took out a sealing scroll, disdainfully throwing the contents inside at Yakushi Kabuto as if it were trash. This was just a half-finished product from his experiment, which perfectly met the needs of that schemer Danzo. It was indeed a very worthwhile deal.

"Yes, Lord Orochimaru, I will personally deliver it to Lord Danzo," Kabuto Yakushi said, taking the scroll and carefully placing it in a lining of his pocket.

"By the way, when we get back this time, we'll have Danzo arrange for you to enter the Konoha Academy. That plan is about to begin," Orochimaru licked his lips, revealing an excited expression.

Since being tricked by Itachi, he has not only lost his respect for the Sharingan, but has become even more passionate and eager to obtain a real Sharingan body.

He later learned from Danzo that Itachi's younger brother was not dead and was still studying at the Ninja Academy. Seven-year-old Sasuke, Itachi's younger brother, was perfect for his research.

By the time he completes his research, Sasuke Uchiha will have grown up, and he will be able to take over Sasuke's body and truly possess the Sharingan, hehehe...

Hehehehe—

……

at the same time--

The Root ninjas who were searching for Kabuto Yakushi near the hot spring town, after finding nothing, all gathered in the hot spring town. When the four met, they all shook their heads slightly, indicating that their tracking of Kabuto Yakushi had failed.

They didn't find Orochimaru's lair there, but fortunately, Lin Chuan and his two companions were unharmed. Protecting Lin Chuan and his companions, and tracking Kabuto Yakushi in search of Orochimaru were among their missions this time.

"If you can't find it, just report it truthfully..."

"Orochimaru hasn't been found for quite some time now..."

"I think Lord Danzo will understand..."

The four of them quickly figured out the reason for the mission's failure, then silently dispersed, splitting into pairs to keep an eye on Lin Chuan and Shan Zhongfeng respectively.

It wasn't until Kabuto Yakushi reappeared, appearing in the hot spring town, which happened to be the same hot spring where Lin Chuan was, that he arrived at the No. 1 bath where Lin Chuan was soaking.

Splash, splash—

"Senior, what brings you here?" Lin Chuan was still soaking in the hot spring when he heard the sound of water and noticed Yakushi Kabuto's arrival. It wasn't a time when no one was around, so he called him "senpai" since someone was there.

"I'm here to soak in the hot spring too. You're my partner, who else would I come to if not you?" Kabuto Yakushi said with a smile as he slowly submerged himself in the hot spring and enjoyed a relaxing bath.

"We'll set off back to the village tomorrow. This time we'll go this way," Yakushi Kabuto said, closing his eyes as he enjoyed the hot springs to relieve his fatigue, as he talked about the route back to the village.

"I understand," Lin Chuan said. Seeing Dou tilting his head back to soak in the bath, he also tilted his head back to soak. At least he wouldn't have to kill bandits anymore when he got back. He felt completely relaxed and could finally get some rest.

……

The next day.

The four arrived outside the hot spring town, got ready, changed back into their Anbu uniforms, and headed into the forest, intending to cross the Land of Rice Fields, enter the Land of Fire from the border of the Land of Rice Fields, and then return to Konoha Village.

This journey was relatively quick, as they didn't have to take detours or kill bandits, and the four of them soon returned to the root of Konoha.

Upon returning to Root, Danzo couldn't wait any longer. He first read the mission observation report of the four members. This report was not written by Kabuto Yakushi, but by the four Root ninjas.

The report stated that Yamanaka Fu and Aburame Torune performed exceptionally well, both receiving an A-rank rating from the four Jonin.

Finally, there was Lin Chuan's observation report, which stated that Lin Chuan had a strong mental fortitude, did not experience any discomfort during his first killing, adapted quickly to the Root's mission, and performed exceptionally well overall.

They rated Lin Chuan as A, and the team leader among the four even gave him an A+ rating.

Overall, Lin Chuan performed better than Yamanaka Fu and Aburame Torune.

"Not bad, not bad, as expected of the genius I have my eye on," Danzo put down the observation report and went to the bridge at the Root exit, where he met the four members of the Yakushi group who had returned from their mission.

"Lord Danzo, this is the sealing scroll he asked me to give to you," Kabuto Yakushi said, not addressing Orochimaru by his name directly, but referring to him as Orochimaru in the presence of others.

"You've done a great job on this mission," Danzo said, taking the sealed scroll without immediately examining it. If he wasn't mistaken, the scroll contained what he wanted.

He was quite satisfied with Lin Chuan and the other two's performance, but he didn't show it on his face. He immediately said to them, "You can all go to the ninjutsu room and choose a ninjutsu. Go..."

"Yes, Lord Danzo," the four replied, and waited for Danzo to turn and leave before heading towards the ninjutsu room.

This time, Root ninjas led them there, so Danzo's procedures weren't needed. The four of them went to the ninjutsu room, each chose a ninjutsu, left the ninjutsu room, and returned to their dormitory to wash up and go to sleep.

Lin Chuan chose another water-style ninjutsu this time. He returned the scroll of the water-style ninjutsu "Heavenly Cry" that he chose last time to the ANBU guarding the gate.

From beginning to end, he never told Kabuto what the two ninjutsu he had chosen were. It is estimated that only Danzo and the gatekeeper ANBU knew which ninjutsu he had chosen.
