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

Meanwhile, as the battle in the canyon raged, reinforcements from the Land of Iron finally arrived, led by Okisuke, a subordinate of Admiral Mifune and a renowned high-ranking samurai.

"It's Lord Okisuke! We're saved!" The warriors of the Land of Iron who were holding out in the canyon, as well as the warriors of other vassal nobles, all saw a glimmer of hope for survival.

There was nothing they could do. From the moment they encountered the enemy, they had been on the defensive, and they were also betrayed by their own comrades. Those mercenary warriors who had been brainwashed by the evil god cult had been lying in wait until now before making their move, catching them completely off guard.

Fortunately, reinforcements arrived, so they were not fighting alone. Shirakumo Hayato and Tekuno also breathed a sigh of relief. Both Iwa and Kumo ninjas were giving these two Konoha Jonin special care.

"The Land of Iron is not a place for you to fight," Okisuke said, raising his hand and sending the hundreds of samurai he had brought charging towards the ninjas on both sides of the canyon.

Hundreds of samurai charged in, causing the Iwa and Kumo ninja who were lying in ambush to consider retreating. They were unsure whether their mission objective had been achieved, but both sides knew they had been tricked by the Konoha ninja.

Tekuno is not Hyuga Tokuma at all. The disappearance of the Hyuga clan likely means the mission has failed, which is why they are taking special care of these two Konoha ninjas.

Now that enemy reinforcements had arrived, both sides retreated, and the warriors of the Land of Iron had no intention of pursuing them.

Those were ninjas from the Five Great Nations. It was no easy feat to repel them. There was no need to pursue them further, since they were no match for them anyway. Moreover, the Land of Iron prides itself on being a neutral country, and pursuing them across borders could very well lead to war.

"Konoha Jonin, I want to know if your client is safe," Okisuke said as he approached Shirakumo Hayato after seeing the enemy retreat, inquiring about the client's situation.

"I don't know either. Let's go back to our border outpost to rest and we'll know the answer tomorrow." Bai Yun looked up at the sky in the morning. The battle lasted until sunset. They fought to the very end and their condition was not very good.

"Alright," Okisuke said, having heard what Shirakumo had said earlier. He had no other choice but to turn to the support troops and order, "Leave four of you with me to the border outpost of the Land of Fire. The rest of you go back..."

"Yes, Lord Okisuke," the samurai unit received the order, and the mid-level samurai took command, leading the remaining samurai back to the capital of the Land of Iron.

Then, the able-bodied warriors helped the wounded, and everyone slowly walked towards the border post. By the time they returned to the border post, it was already midnight.

When Baiyun and the others arrived, they found that there were no servants who had retreated. They had seen many corpses on the way, and the only one who had returned was a heavily wounded warrior who had barely escaped from the enemy.

Only after everyone inquired did they learn that the last two samurai who stayed behind to protect the client had lost track of the client's daughter and did not know where she had gone.

Lin Chuan stayed with them, but faced with an enemy that outnumbered them, they all chose to run away. In the end, the three of them got separated, and only the samurai returned to the border post.

Upon hearing this result, everyone was stunned and could only wait quietly for news the next day, hoping that good news would come from the direction of the capital of the Land of Iron that the client had arrived safely!

……

At the same time—

Lin Chuan had already seen enough of this PDA. The young warrior and the girl had just escaped, and they were already being all lovey-dovey by the river. Did they think he, an outsider, didn't exist?

He saw the two of them snuggling by the fire, whispering sweet nothings and fast asleep, completely oblivious to any danger. Just as he was about to knock the two of them unconscious and take them back to prevent them from being together, he heard a rustling sound coming from the woods.

After the swishing sound subsided, two ninjas landed on the shore. Judging from the reflective patterns on their headbands, they were actually two Cloud Ninjas.

"Hehe, I didn't expect to have such an unexpected gain?" Yunren looked at the two people huddled by the fire. They guessed that they were probably survivors who had escaped from the caravan earlier, but they didn't know their identities.

On their way back to the Land of Lightning, they found a series of messy footprints on the ground and decided to follow them to investigate. That's when they discovered the two girls by the river.

"Let's go, grab those two and ask them who they are," another Cloud Ninja quietly took out a kunai, licked his dry lips, and leaped down.

click-

The two Cloud Ninjas had just landed when they accidentally stepped on a branch that had fallen to the ground while the young samurai was collecting branches. The crisp sound instantly startled the two people by the fire.

The moment the samurai boy was awakened, he turned around, drew his katana, looked at the two approaching Cloud Ninja, and shielded the girl behind him.

"Who are you?" Yunren asked the two young samurai as soon as they woke up.

"We're just passing by, we'll leave now," the samurai boy said, his eyes instinctively darting away from the two of them when he heard Yunren's question, and he held the girl even tighter.

"Looks like a big fish," another Cloud Ninja said, seeing the samurai boy's reaction, knowing that the girl was definitely not simple.

"Don't be afraid, I will protect you," the samurai boy kept protecting the girl as they retreated, but the Yun ninja couldn't wait any longer. He grabbed a kunai and rushed forward with a Body Flicker Technique.

shhhhh--

The young samurai swung his sword several times, but all of them were blocked by the kunai of the Cloud Ninja. Just then, another Cloud Ninja, who had already disappeared, kicked the young samurai, sending him flying. The Cloud Ninja who was attacking the young samurai seized the opportunity to grab the girl's wrist.

"Ahhh, Masaki-nii, come save me!" The girl's scream made the fallen samurai boy get up instantly, raise his sword and charge at the Cloud Ninja again.

"You deal with him first, I'll interrogate this girl," Yunren said, having his companion hold the boy back. He immediately raised his hand to form a hand seal, casting an illusion on the girl, and began questioning her about her identity.

"Let her go!" The samurai boy's eyes turned bloodshot when he saw the girl being treated so roughly. They had just confessed their love and pledged their lives to each other. He could not let the ninja take the girl away. He immediately unleashed a speed even faster than before and stabbed the cloud ninja with his sword.

At this moment, the Cloud Ninja looked at the young samurai with a mocking expression, as if he were looking at a clown. They didn't care at all. From the previous test, they had already seen that the young samurai was not even as good as a genin. How could he possibly be a match for the two chunin?

puff-

But with a soft "pfft," his sinister laugh was shattered as the kunai he threw pierced the boy, and the samurai boy's short sword also pierced him through.

"How is this possible?" Yunren stared at the katana piercing his chest, realizing he had been stabbed through the chest. He then looked at the young samurai before him and noticed that the boy's eyes were covered in crimson, with no white visible. He muttered to himself, "Isn't this guy afraid of death?"

puff-

The boy drew his katana, and the Cloud Ninja fell to the ground. His Cloud Ninja companions looked over and saw a horrifying scene: the young samurai was covered in blood, with four or five kunai stuck in his body, and he charged at him with a bloodstained longsword.

He had gotten the information he wanted, and the girl was indeed one of the mission targets. He picked her up and threw her at the charging samurai boy.

Seeing that it was a girl who had been thrown at him, the samurai boy regained his senses, pressed down on his blade, raised his hand to catch the girl, and the two of them flew backward together.

At the same time, Yunren took out a signal flare, preparing to fire it into the sky to signal their evacuated comrades to come and provide support. With this girl alive, their mission would not be considered a failure; at least they would have completed half of it.

puff-

Just then, a short knife pierced through the chest from behind the Cloud Ninja, going straight through his heart. The signal flare the Cloud Ninja was about to release was also held down by a hand, preventing it from being fired.

"Enough with the nonsense," Lin Chuan said, drawing his short sword, snatching the signal flare and throwing it into the water. As the Cloud Ninja lay dying, he opened his eyes wide and finally saw who had ambushed him. He saw Lin Chuan's ANBU mask and that familiar Konoha ANBU uniform.

He never expected that there would be Konoha's Anbu here. He realized that it was impossible to take the girl away. Their mission had ultimately failed, and he had completely lost his life.

To ensure the enemies weren't completely dead, Lin Chuan, carrying a bloodstained dagger, approached the Cloud Ninja and stabbed two of them in the eyes, stopping only after piercing their skulls. He then gently wiped the bloodied blade on their clothes. Ninjas are meant for assassinations; what kind of ninja fights head-on with bayonets? These two deserved to die.

He wiped the dagger clean, sheathed it again, and then went to the unconscious samurai boy and girl to check on them.

The girl was fine, but she was unconscious due to the illusion. The samurai boy, covered in blood, looked rather pitiful. But why had all the kunai on the samurai boy fallen off? Shouldn't they have pierced through the samurai boy's body?

He reached out and pulled open the samurai boy's blood-stained clothes, finding that the wounds on the samurai boy's body had stopped bleeding. He gently wiped away the blood and found that only a white line remained on the wound, which then disappeared in the blink of an eye. The hideous knife wound was instantly healed.

"Holy crap, that's amazing? This self-healing ability is just too incredible!" Lin Chuan fell into deep thought, then splashed a ladle of water on the samurai boy's chest. After washing away the blood, he found that there were no wounds on the samurai boy's chest, and he had a rough idea of ​​why.

There are only two possibilities for such a strong self-healing ability appearing in a teenager...

The first scenario involves a young boy who possesses a special constitution, given that Hashirama Senju's self-healing ability is also terrifying.

The second possibility is that the boy is a member of an evil cult and possesses an immortal body. Apart from the protagonist and others with special physiques, he also has super self-healing abilities. Forget about the supporting characters; they are definitely all evil cultivators.

Hidan is a guy who likes to hurt himself, and along with his self-harm comes an amazing self-healing ability; otherwise, Hidan would have killed himself long ago.

Regarding Hidan's Jashin religion's immortality ability, he actually had another guess: the immortality was probably Orochimaru's doing. The Land of Rice Fields and the Land of Hot Springs are neighboring countries, and Orochimaru needed human subjects for experiments, so what he lacked most was human subjects.

No country is so chaotic that it can provide all the human materials one desires. Therefore, Orochimaru's goal was definitely to create chaos in the Land of Hot Springs before establishing the Sound Village.

He was unaware of Orochimaru's relationship with the Jashin, but since there were immortal ninjas in the Land of Hot Springs, it was impossible for Orochimaru, who pursued immortality and eternal life, not to have studied it.

Perhaps it was the secret techniques of the Jashin religion combined with Orochimaru's forbidden techniques that brought about an unexpected effect, creating many legends of immortality.

As for why Orochimaru abandoned the secret techniques of the Jashin Cult?

That's easy. Orochimaru, such an arrogant ninja, must have discovered the flaws in the evil ninjutsu. How could Orochimaru be manipulated by an evil god? Anything that Orochimaru looks down on must be trash.

Even the most sinister techniques probably come at a price, the price being Hidan's silver hair. Medical ninjutsu, with its accelerated healing and self-healing abilities, all consume the number of cell divisions a person can make. And since the number of cell divisions a human can make is limited, lifespan is the price of immortality.

To claim immortality before solving the limitation on the number of times cells can divide is simply dishonest!

"Spirit Summoning," Lin Chuan raised his hand and pressed it to the ground. Black runes instantly covered the ground, summoning a flock of crows.

He stared at the crows he had summoned through psychic abilities. This was the first time he had ever used crows for a mission. Pointing to the two unconscious men on the ground, he shouted to the crows, "You guys split up, grab them and come with me..."

A battle took place here. Although the Cloud Ninja won't be coming for the time being, if these two Cloud Ninja don't go back, they will definitely be discovered tomorrow, causing more Cloud Ninja to come looking for their missing Cloud Ninja comrades. Sooner or later, they will find this place.

He wasn't thinking of going back to the border between the Land of Iron and the Land of Fire, but rather heading directly to the border between the Land of Rice and the Land of Fire, where there was a border post.

Once he arrives at the border post here, he will have the communications eagle notify Baiyun Zaojian and the others over there to come over, and then he will have completed his mission.

He wasn't worried about the danger to Shirakumo and the others. It would take several times the strength to intercept a Konoha Jonin trying to break through, and with the cooperation of the Iron Country samurai, breaking through and returning to the border outpost would be quite simple.

The riverbank wasn't far from the border post. He had the crows drag the two of them while he ran as fast as he could through the woods, but he couldn't outrun the crows. He finally arrived at the border post at dawn.

"Who goes there?" The Konoha border ninja saw a man in black appear, and when they recognized him, they exclaimed in surprise, "Anbu? Please identify yourself..."

"I'm not from the Anbu. My name is Chiba Rinkawa, a teammate of Captain Shirakumo Hayabusa on missions," Rinkawa removed his mask to reveal himself to the Konoha ninja. He then had the crow put the girl down and dispelled the summoning jutsu, before continuing to explain:

"Captain Morning is at the outpost in the Land of Iron. Please inform him as soon as possible to verify. These two are the targets our team is escorting for this mission. Please make proper arrangements for them..."

"You're not an Anbu, so how come you have Anbu uniforms?" The Konoha ninja had someone release a communication eagle to verify the information while continuing to question Lin Chuan.

"This is the equipment I received when I joined Root. That's all I can say," Lin Chuan said, putting down his mask and short sword. He sat outside the outpost without going anywhere, and took out food and ration pills to replenish his strength and chakra.

The communications eagle quickly brought news that Shirokumo, who had rested for half a night, and Oki, a samurai from the Land of Iron, had arrived at the outpost with their men. They saw the client's daughter, who was unconscious due to an illusion spell but was otherwise unharmed, which relieved Shirokumo.
