My Sign-in System in Naruto

After persuading Aburame Torune to leave, Sarutobi Hiruzen and his group set off immediately, continuing their journey to the Land of Iron to attend the Kage Summit.

The rest of the journey was uneventful, and they arrived at their destination without further interruptions.

When Haru, Hiruzen, and Fu stepped onto the territory of the Land of Iron, a familiar voice echoed in Haru's ears once again.

CONGRATULATIONS, HOST! YOU HAVE SUCCESSFULLY ARRIVED AT THE CHECK-IN LOCATION. CHECK-IN HAS BEGUN!

CHECK-IN PROGRESS MUST REACH 100%. LEAVING MIDWAY WILL RESULT IN CHECK-IN FAILURE!

Haru blinked slightly, looking down at the ground beneath his feet.

'It seems that the check-in system considers entering the Land of Iron as a success,' Haru thought to himself, eagerly anticipating the reward that would come once the progress reached 100%.

The process only took a few breaths.

"The Land of Iron," Hiruzen murmured as he observed the surroundings, a hint of nostalgia in his voice.

The Land of Iron was a nation nestled deep within the mountains, making it a natural fortress that was easy to defend but difficult to attack. Due to its geographical location, the country experienced distinct seasons, and during winter, it was blanketed in thick snow.

In fact, the reason the Land of Iron had managed to remain neutral during wars wasn't just due to agreements between ninja villages. Its geographical advantages played a significant role as well.

Because of the heavy snowfall, once winter arrived, the Land of Iron couldn't produce any food. Even if it were conquered, the stored food wouldn't be enough to sustain a large population, making it a burden for any invading nation.

Additionally, the Land of Iron bordered several countries, making it a natural buffer zone. In other words, if any nation harbored ill intentions toward the Land of Iron, they would face intervention from other countries before they could conquer it.

The geographical advantages of the Land of Iron also made it easy for its people to hold their ground.

Any sensible leader would understand that attacking this place was a thankless task.

Easy to defend, difficult to attack, and with barren soil.

"Let's go," Hiruzen said, taking a deep breath. However, it was precisely because of these reasons that the Land of Iron had remained untouched by war, and the air quality here was exceptionally good.

At the same time, Haru's check-in progress reached 100%.

CONGRATULATIONS, HOST! CHECK-IN SUCCESSFUL!

REWARD OBTAINED: ASAUCHI AND SWORDSMANSHIP MASTERY!

Upon hearing the familiar voice, Haru was momentarily stunned.

Although the previous check-in rewards had hinted that this one might be related to samurai or swordsmanship, the specific reward still surprised him slightly.

However, the reward didn't materialize in Haru's hand. Instead, it was stored in his inventory and could be retrieved through mental extraction.

Haru instinctively glanced at the Asauchi lying quietly in his inventory.

From its appearance, it was just a slender, snow-white katana, no different from the weapons used by the Anbu in the Naruto world.

However, as a transmigrator, Haru was well aware of the exaggerated potential of this weapon.

Its true origin wasn't from Naruto but from another anime called Bleach. It was the name given to a Zanpakutō before it achieved its Shikai.

Forged by Ōetsu Nimaiya, the "God of the Sword" and creator of the Zanpakutō, the Asauchi was known as the most powerful Zanpakutō with infinite developmental potential.

When materialized, it took the form of a naked humanoid with only a mouth and nose.

At the same time, it would evolve into a unique Zanpakutō as its user infused it with their spirit and beliefs.

To put it bluntly, this seemingly ordinary Asauchi was far more extraordinary than any swordsmanship mastery.

"Every Zanpakutō has its own unique ability," Haru thought as he gazed at his Asauchi, feeling increasingly excited.

He began to wonder what kind of ability he would get from this Zanpakutō.

Would it be Kyōka Suigetsu, the strongest illusion-type Zanpakutō?

Or Hyōrinmaru, capable of freezing the heavens and earth?

Or perhaps Ryūjin Jakka, which could burn all enemies to ashes with a single slash…

However, the awakening of a Zanpakutō was determined by its wielder.

For example, Aizen, who excelled in deception and disguise, got from his Asauchi the ability of Kyōka Suigetsu.

Ichigo Kurosaki, with his immense spiritual pressure, obtained Zangetsu.

And then there was Kenpachi, whose Zanpakutō, in Haru's opinion, was the most unreasonable of all.

"Although I don't have spiritual pressure, chakra and spiritual pressure seem similar—both are manifestations of mental and physical energy. The denser they are, the stronger the power."

Based on Haru's understanding, he believed that chakra in Naruto, spiritual pressure in Bleach, the Cosmos in Saint Seiya, ki in Dragon Ball, and Nen in Hunter x Hunter were essentially the same thing. Sometimes, their manifestations were even similar.

For example, Hashirama Senju and Kurama's chakra were so powerful that they could easily overwhelm their opponents, rendering them unable to resist.

This was very similar to spiritual pressure and Haki.

In other words, Haru could infuse his chakra into the Asauchi, and attribute it a unique ability.

"Haru?"

Noticing Haru's deep contemplation, Hiruzen called his name, pulling him back to reality.

At the entrance to the Land of Iron, guards were already stationed.

Upon noticing Hiruzen's group, one of the guards quickly approached, bowed respectfully, and introduced himself.

The guard was none other than Rikaku, a subordinate of Mifune, the general of the Land of Iron. Rikaku had served as Mifune's bodyguard during the Five Kage Summit.

Although not a ninja, he possessed strength comparable to a Jonin.

"Lord Hokage, please follow me. General Mifune has been waiting for you," Rikaku said respectfully.

Despite the Land of Iron's neutrality, it was well-informed about the other nations.

Especially Sarutobi Hiruzen, the renowned Third Hokage of Konoha.

Not only was he known as the "Professor," but he also bore the title of "The Shinobi Monarch." (from where??)

Even Mifune held great respect for this ninja.

Hiruzen smiled and nodded, allowing Rikaku to lead the way.

Of course, Hiruzen was well aware that while the Land of Iron appeared neutral and uninvolved in any shinobi wars, its neutrality was partly due to the strategies employed by its general.

Deep within these mountains, traps were scattered everywhere. Unless one was familiar with the terrain, it would be nearly impossible to enter the Land of Iron safely.

"Everyone, please follow my steps closely. There's only one safe path into the Land of Iron, and it changes periodically," Rikaku said, walking ahead without turning back.

This was, in fact, a warning. Trying to memorize the correct path would be pointless.

Haru, meanwhile, observed the guards. They all wore silver-layered armor and carried at least two swords on their right side.

Although they weren't ninjas, they also utilized chakra in combat.
