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

For several days, the caravan traveled along the official roads of the Land of Fire. After passing through several villages, the commissioner added a few more carriages so that the servants could ride in them, which greatly increased the caravan's speed.

Lin Chuan remained in the third carriage, sitting on the roof of the client's daughter's carriage. Now that he knew the client's daughter's true identity, he naturally focused his attention on the noble lady disguised as a maid.

He didn't pay much attention to the girl. If a Konoha ninja paid too much attention to a maid, it would arouse suspicion from those with ulterior motives. So he maintained his previous indifferent persona and rarely spoke to the girl's loud and boisterous behavior.

Seeing his indifference, the girl lost interest in finding him and followed the samurai boy all the way, practicing her swordsmanship. She even said that she also had a dream of becoming a samurai and wanted to be a female samurai.

If her family agrees, the girl might be able to become a female warrior. After all, given her family's circumstances, becoming a warrior would be quite easy.

Time passed quickly, and after half a month, they finally crossed the northern border of the Land of Fire and arrived at the border outpost on the way to the Land of Iron, where they could rest and recuperate.

Upon entering the border outpost, the Konoha quartet finally had a hot meal. During their journey, they had been eating soldier rations for lunch and only had time to prepare a simple hot meal in the evening. Here, someone had already prepared a hot meal for them.

After having a hot meal, it was Lin Chuan and Bai Yun's turn to keep watch in the morning and monitor the movement of the entire convoy. Especially at such a critical moment, they absolutely could not be careless and had to prevent enemy ninjas from attacking the border of the Land of Fire.

They were unaware of the assassination missions received by the other two ninja villages. If the money was sufficient, it wouldn't be impossible for enemy ninjas to storm the border in order to complete their missions.

Friction frequently occurs along the borders of the five major powers. Even if a border incident occurs, it's usually a minor matter with a flimsy excuse, and they simply walk away afterwards without any problem.

However, Lin Chuan felt that the enemy wouldn't be that stupid. Once they crossed the border, the enemy ninjas would only face the caravan guards. But if they attacked the border of the Land of Fire, they would face the Konoha border guards. It didn't seem worth it at all.

However, none of them noticed that at some point during the night, one of the samurai who had come here with the caravan got up to urinate, and a worm crawled out of his trouser leg. The worm quickly dug into the soil and disappeared.

When the insects appeared, they were already outside the Land of Fire. A ninja wearing a headband from Iwagakure was holding something that attracted the insects, and the insects were clinging to it.

The insect didn't convey any message, but the Iwa ninja immediately reported, "Captain, they have reached the border of the Land of Fire and are about to enter the Land of Iron..."

"It's finally here, an S-rank mission. Have you investigated the target of the assassination?" The Iwa ninja captain looked at his subordinates; they had been waiting for this for a long time.

"The news came from the Land of Hot Water. They used two groups of wandering samurai to probe and figure out the defenses around the target. They also said that the samurai hired by the target will cooperate with us. We only need to deal with the samurai from the Land of Iron and the ninja from Konoha..."

"Who are the Konoha ninjas this time?" The Iwa ninja captain's eyes darkened when he heard that there were Konoha ninjas among them. As their old rivals, he knew the Konoha ninjas all too well.

"The Jonin leading this team is Hayato Shirakumo, and one of them even possesses the Byakugan. Our ambush might very well be discovered..."

"Damn the Hyuga clan!" The Iwa ninja captain cursed under his breath when he heard the Byakugan. He hadn't expected to encounter the Hyuga clan this time. It must be a branch family Hyuga. Not only would it be troublesome to face them, but he also wouldn't be able to get the Byakugan.

The Iwa ninja captain immediately decided to change the battle plan, instructing his subordinates: "An ambush is pointless. Notify the Kumo ninja over there and share the intelligence with them. We can cooperate and take action in the canyon; the terrain is advantageous to us..."

"Yes, Captain..."

……

The next morning, the convoy packed up their tents and other items again, had breakfast, and continued their journey. This time, after leaving the Land of Fire, they entered the Land of Iron.

The Land of Iron is located further north on the continent, and it gets colder the closer they get to the capital of the Land of Iron. Fortunately, they wore an extra layer of clothing when they left the outpost.

Lin Chuan tightened his clothes, took out the map of the Land of Iron, and examined it carefully, trying to guess where the enemy would strike.

In fact, the four of them had gathered together last night to calculate the situation, and they all agreed that the enemy would make their move in the first canyon they entered the Iron Kingdom.

The canyon is the only route the convoy can take. The terrain of the canyon is unfavorable to our side. The geology of the canyon is relatively hard, which is a great advantage to both the Rock Ninja and the Cloud Ninja.

Because most of the Iwa ninja's ninjutsu is Earth Release, while most of the Cloud ninja's ninjutsu is Lightning Release, the hard geology of the canyon allows the Iwa ninja to perform better, while the non-conductive geology is more conducive to the Cloud ninja's use of Lightning Release.

They no longer have a geographical advantage, but fortunately, they have the right timing and the human resources are evenly matched; it all comes down to which side has the stronger edge.

He carefully put away the map. There was a red circle further north on the map, which marked the capital of the Iron Kingdom and their meeting point.

If they get separated during the battle, they must regroup in the capital of the Land of Iron. Regardless of whether the mission is completed or not, they must proceed to the final destination of the mission: the capital of the Land of Iron.

After everything was ready, he continued to sit on the roof of the carriage, looking at the canyon that was getting closer and closer. They would arrive at noon and cross the canyon at noon.

After lunch, Lin Chuan's four-person team gathered for the last time. Bai Yun began issuing tasks in the morning: "Kuno, you follow me later and use the transformation technique to transform into Tokuma's appearance..."

"Tokuma, you don't need to cross the canyon. When the battle breaks out, this place will attract all the enemies' attention. You take the client and go along another route, only taking the client and hurrying along. There will be samurai to meet you in the capital of the Land of Iron..."

"Understood, Captain Hayabusa," Hyuga Tokuma knew why Shirakumo Hayabusa had assigned him this mission. With his Byakugan, it would be easy for him to avoid enemy ambushes; the two of them wouldn't be discovered at all.

"Lin Chuan, split one of your water clones into Kuno. When the battle breaks out, your convoy will be at the back, giving you a chance to escape the canyon. Then, follow the four Iron Country warriors protecting the third carriage, along with the other two warriors who are the clients, and retreat together to the Fire Country border outpost. There will be people there to meet you..."

"Understood, Captain," Lin Chuan nodded gently. He knew he wouldn't have any dangerous missions, as long as they could retreat back to the border outpost of the Land of Fire.

Once the battle here is over, regardless of who wins or loses, the client will arrive safely in the capital of the Land of Iron. The client's daughter can come to pick them up later, and then they will head to the capital of the Land of Iron.

The enemy's primary target is definitely the client himself; the daughter should only be a secondary target. If even the client cannot be killed, then the mission will fail, and killing the client's daughter would be meaningless.

"Get ready and set off," Baiyun gave the final mission instructions in the morning. Success or failure, life or death, would depend on individual fate.

As planned, Lin Chuan's shadow clone found a secluded place with water and created a water clone, which then transformed into Tekuno's appearance and continued to accompany the caravan on its journey.

In fact, he secretly used Shadow Clone Jutsu when he left the border of the Land of Fire. He valued his life more than Baiyun had thought earlier, because Shadow Clone Jutsu would divide his chakra equally, and at that time it directly took away the amount of chakra of an A-rank ninjutsu from him.

With the aid of the soldier's ration pills, and after a morning of recovery, his main body, hanging at the back of the convoy, had fully recovered his chakra, returning to the chakra level of two A-rank ninjutsu. Now he was just waiting for the battle to begin.

Boom boom boom—

The battle broke out as expected. When both sides had their cards on the table, they knew exactly when and where the battle would break out, so there were no surprises.

The Iwa ninja used two Earth Release combined ninjutsu to block both ends of the canyon as soon as they appeared, followed by another Earth Release combined ninjutsu, Rock Collapse.

With the aid of ninjutsu, the rocks above the canyon collapsed and crashed down, instantly filling the air with dust and covering the surrounded convoy.

"Vacuum Sword," Bai Yun drew his long wind sword in the morning. The sword emitted a low hum and instantly cut out several piercing sounds, dispersing the sky-covering dust and shredding the huge falling rocks into pieces. The damage from the falling rocks was instantly reduced.

Sizzle, sizzle—

Suddenly, a thousand birds cried out from above the canyon on the other side. It wasn't Kakashi's Lightning Blade, but a combined Lightning Release ninjutsu from the Cloud Ninja.

Faced with this combined Lightning Release ninjutsu, even Hakuun Hayato couldn't care less about anything else. He had already achieved his goal: to show the enemy that Hyuga Tokuma was by his side and that the servants at the back of the convoy had already retreated.

The servants of the person who commissioned the mission are not of much value, and the enemy ninjas that are chasing them are generally no more than Chunin. What he and Tekuno need to consider next is how to survive and when the support from the Land of Iron will arrive.

……

at the same time--

Lin Chuan's shadow clone was positioned behind the canyon's encirclement. Before they could even enter the canyon, two earthen walls were erected, which was one of Bai Yun's plans earlier that day.

Baiyun deliberately lengthened the distance between the caravans in the morning. Once the Iwa ninjas didn't make a move, and all the additional carriages they had added entered the canyon, and the carriages in front left the canyon, the Iwa ninjas would lose their opportunity to act.

"Hurry, we'll stop them!" Four warriors from the Land of Iron stepped forward, drawing their chakra swords to block the Iwa and Kumo ninjas that appeared ahead. The enemy outnumbered their own forces by two.

"Run! Stop looking! Go back to the border outpost from last night!" Lin Chuan's shadow clone urged the stunned crowd to evacuate. The group was terrified and their legs wouldn't move.

But some people weren't idle. The samurai boy was the first to grab the girl and run. The rest of the people only realized what was happening when they saw the two running away and then turned tail and ran.

The two remaining trusted samurai behind the client saw their target run away and chased after her with their swords drawn; they couldn't let the young lady out of their sight.

Lin Chuan looked at the shadowy figures above the canyon. The Iwa ninja and the Kumo ninja were really going all out. This time, both sides had sent at least two teams of ninjas. Fortunately, neither side was targeting them. Before he turned to run away, he silently prayed for Shirakumo Hayato and Tekuno, hoping that the two of them could break through successfully!

Meanwhile, he and his clone, Tekuno, also fled behind the others. However, ninjas are much faster at escaping and quickly overtook the others, but they were soon caught up by the enemy.

Kuno, a master of water-based skills, looked at the pursuing enemies behind him and shouted to Lin Chuan, "Run! I'll hold them off..."

"Tsk, you water clone are getting all hot-blooded, aren't you?" Shadow clone Lin Chuan was speechless and could only run away as fast as possible. As long as he could run faster than those servants, he would be fine. They would only come after they were all dead. In any case, he was just bait to attract fire.

At this moment, Lin Chuan secretly took out his ANBU mask and put it on, then took off his coat, revealing his ANBU uniform.

When you're out in the world, you choose your own identity. Compared to the identity of an ordinary genin, the identity of a Konoha ANBU member is more likely to intimidate the enemy and make them hesitant to make a move. After all, ANBU members are usually elite ninjas who go on missions in groups of four or two. This is called creating a false identity, since the enemy won't dare to verify it anyway.

But just as he finished changing his clothes, he noticed the young samurai and girl running ahead of him. It seemed they were running in the wrong direction; they were actually heading towards the Land of Fields.

"Damn, are they out of their minds? Going to Orochimaru's territory? What are these two up to?" Lin Chuan immediately turned around and chased after them. The girl was his mission target, so he slowly trailed behind them.

The girl and the young samurai ran for more than three hours before stopping, panting heavily, and reached the border of the Land of Fields.

Two hours earlier, Lin Chuan had received a message from his shadow clone that the shadow clone had been caught up and killed by two Iwa ninja while fleeing to the border outpost of the Land of Fire.

There were four enemies who caught up with him: two Iwa ninja and two Kumo ninja. After killing the slow-moving servants, the four of them caught up with him and the two samurai confidants of the commissioner.

Outnumbered four to three, the advantage lay with the enemy, so his shadow clone showed no hesitation and turned to run. However, it was caught by an Iwa ninja who cruelly killed it.

I wonder if the Iwa ninja chasing him were afraid of being ambushed when the shadow clones exploded. It would be hilarious if they just stood there waiting for his real body to appear!

However, that's a story for later. He wanted to see what the two were up to. After observing them along the way, he discovered that they seemed to be planning to elope. It was quite a juicy gossip in the entertainment industry.

A samurai actually wanted to elope with a noble lady. It turns out that the young samurai himself knew that continuing to follow the girl would lead nowhere, otherwise he wouldn't have eloped with her.

If the young samurai could achieve what Mifune did, becoming the leader of the samurai of the Land of Iron, or even a general of the Land of Iron, perhaps he would be worthy of the girl. But forget it now; every single one of those samurai of the Land of Iron is stronger than this weakling.

If you can't even endure the hardship of sword training, you lack the determination to become a strong person. Your heart is filled with thoughts of your sweetheart, so your future achievements will be limited...
