Naruto Card King

Haruto Saito finally realized where the problem lay. He had studied it repeatedly before but found no results because he hadn't moved. This ability required the Black Warrior to be in motion. Only by making a forward movement could it be effective. In other words, if he wanted to move in a particular direction, he needed to make a forward motion toward that direction.

Leaning forward was enough!

"Black Warrior Flash, this is it!" Haruto recalled that Jiraiya had mentioned another one of the Black Warrior's four abilities.

Black Warrior Flash, also known as Black Warrior Instant Step, was a technique similar to the ninja Body Flicker Technique, but it was different. In terms of effectiveness, it was far stronger than the basic Body Flicker Technique. The latter required hand seals, had a noticeable activation delay, and produced chakra fluctuations that could be traced.

Black Warrior Flash had none of these issues.

It was true instantaneous movement, almost like a time-space Body Flicker Technique. It required no hand seals, activated instantly, and produced no chakra signatures. However, compared to the pinnacle of time-space ninjutsu—the Flying Thunder God Technique created by the Second Hokage, Tobirama Senju—it fell short by a wide margin.

The difference in range alone was immense. Theoretically, the Flying Thunder God Technique had no distance limitation. The deeper one's mastery, the farther one could sense the Flying Thunder God markings, enabling teleportation across vast distances.

Meanwhile, Black Warrior Flash had a very short range. It could only be used for close-range movement, with a maximum distance of no more than a hundred meters.

However, for Haruto Saito right now, this technique was incredibly practical!

In fact, in some ways, it surpassed the Flying Thunder God Technique. Using Black Warrior Flash didn't require pre-set coordinates or sensing special markings. He could teleport just by shifting his body slightly.

"Perfect!" Haruto was very satisfied, even pleasantly surprised.

Because Black Warrior Flash could be used for infiltration, it would significantly reduce the risks he faced when sneaking in. It was exactly what he needed at this moment.

Whoosh!

Haruto, perched on a tree, turned into black smoke and instantly reappeared above the river's surface. Then, leaning forward again, he transformed into black smoke once more, appearing on the opposite bank's treetop in the blink of an eye.

The technique was not complicated to use. As long as one grasped the trick, it was easy to activate.

Haruto once again transformed into black smoke and, like a ghost, instantly appeared at the top of a towering tree nearby.

"Flawless!" Haruto grinned and was about to move again when his expression suddenly changed. At that moment, he felt the activated curse seal energy fluctuations on his Black Warrior Armor rapidly dissipating. Within just two breaths, the previously activated curse seals had all lost their energy, leaving only the markings on his back still active.

Haruto frowned.

What was going on?!

He suddenly felt the Black Warrior Armor beginning to absorb his chakra at an accelerated rate.

It was the same as before. The previously dormant curse seals were being reactivated.

"Could it be that Black Warrior Flash, once triggered by the curse seal, can only be used five times before the seal becomes inactive? And it requires chakra reinjection to reactivate?"

Haruto made a reasonable deduction, as that was exactly what was happening.

He also recalled that Jiraiya had mentioned before that the Black Warriors only used Black Warrior Flash in battle or while escaping—and they rarely used it repeatedly. Even in an entire battle, they would only use it a handful of times. That was why Black Warrior Flash was considered the Black Warrior's most mysterious ability. The outside world could only speculate about it based on surface-level observations, but no one knew the actual mechanics.

Combining Jiraiya's words with his current situation, Haruto could deduce that the Black Warriors didn't avoid frequent use of Black Warrior Flash by choice—it was restricted!

Black Warrior Flash consumed an enormous amount of chakra!

Each activation of the curse seal allowed for only five uses of the technique. After that, it had to be reactivated.

In terms of chakra consumption, this drained at least a quarter of Haruto's total reserves. Given his current chakra capacity, a quarter of his chakra was equivalent to the full reserves of an average Chunin!

In other words, using Black Warrior Flash once would deplete an entire Chunin's chakra!

With such a massive consumption, unless one was a ninja born with an enormous chakra pool, they couldn't afford to use Black Warrior Flash recklessly.

For a samurai, the cost was even more extreme!

Samurai already had far less chakra than ninjas—significantly less!

Haruto quickly injected more chakra into the Black Warrior Armor.

Soon, he retrieved and consumed a low-level chakra recovery card.

After just over a minute, the Black Warrior Flash curse seals were fully reactivated.

He couldn't afford to waste it. Whether his hypothesis was correct or not, now was not the time to experiment. Activating the technique once meant using up a low-level chakra recovery card, and those were too rare to squander.

"Five times. I have five chances. Alright!"

Composing himself, Haruto took a deep breath and continued his journey against the wind and rain.

...

The Baishi Camp was brightly lit in the southern section, where laborers were still hard at work, creating a bustling scene.

In the northern section, under the drizzle, the lights were sparse. It was quiet yet heavily guarded.

Haruto bypassed the southern section and infiltrated the northern area. He slowed his pace, carefully avoiding patrols and sentries, taking a winding route. After nearly half an hour, he finally arrived outside the central mansion.

For him, this was hardly difficult. The sentries and patrols he encountered were ordinary soldiers. The real challenge would come once he entered the mansion, where the guards consisted of samurai and ninjas.

Shrouded in black mist, Haruto carefully crouched inside a drainage ditch outside the mansion, keeping his body as concealed as possible below ground level. His eyes locked onto the mansion, peering through the grass. He brought his hands together once again.

Byakugan, activate!

Although Haruto had used the Byakugan multiple times for scouting, he had only checked the surrounding area before. He could have observed the mansion from afar, but that would have been pointless—people inside moved. If he scouted too early, his intel would be outdated by the time he arrived.

Through his Byakugan, the world turned to shades of gray and white.

Sweeping his vision over the mansion, he counted fewer than two hundred people inside. About 150 of them were either samurai or ninjas, while the rest were servants, maids, cooks, and gardeners. Tanaka Seiji lived lavishly, employing many servants.

Haruto began examining each samurai and ninja one by one. He needed to confirm their identities and assess whether he had an opportunity to assassinate Tanaka Seiji.

As he watched, his eyes narrowed.

The man clad in a black robe standing behind Tanaka Seiji was exactly who he had suspected.

"Damn it… he's a sensory-type ninja!" Haruto's mind screamed.

Too late!

The strange energy wave had already spread toward him, sweeping past his body.
