Kairen immediately entered the system space and asked the Infinite Resurrection System:
"Well? System, what do you think of my idea just now?"
The system replied:
"It's possible, but the host's chakra control ability must be raised to a certain standard."
"No problem!"
Kairen instantly spent 500 experience points to max out his chakra control ability and chakra nature transformation ability.
Moreover, he found that even after reaching max level, chakra control ability could still continue to be improved.
The system explained:
"This is the special trait of the Special Jōnin template. It allows you to break past the template's limit in one specific area, reaching the level of a Jōnin template."
Kairen nodded. That was exactly what a Special Jōnin meant—someone who reached Jōnin-level in a particular field, such as Ninjutsu, Taijutsu, or Genjutsu…
Kairen's chakra control ability could keep increasing, directly surpassing the template's restriction.
He spent another 500 points to push his chakra control ability beyond the max, reaching 200% of the Special Jōnin template's stats.
Kairen then redeemed a High-Level Ninjutsu Development Card. In the blink of an eye, from the 9,000 experience points he had accumulated earlier, only 6,000 remained.
But Kairen didn't regret it. Experience points were meant to be spent on things like this.
"High-Level Ninjutsu Development Card redeemed successfully!"
Kairen immediately stated his request:
"Help me develop a ninjutsu that can control natural fire. As for the form transformation… make it a fire dragon!"
"Ninjutsu development initiated. Progress 1%..."
"Progress 2%..."
"Progress 3%..."
"Progress 50%..."
"Progress 100%!!"
"Ninjutsu development complete. Please name it, host!"
Kairen thought for a moment before answering:
"Let's call it Fire Release: Blazing Flame Dragon!"
"Host has successfully named it. Detected that Fire Release: Blazing Flame Dragon has reached Forbidden Jutsu level. Recorded into the Forbidden Jutsu Scroll!"
Joy welled in Kairen's heart. He had actually gotten a Forbidden Jutsu from a single High-Level Ninjutsu Development Card—rare good fortune indeed.
The Fire Release: Blazing Flame Dragon slowly infused into Kairen's mind—the hand seals, chakra flow, chakra nature transformation, and the amount of chakra needed for release…
Kairen instantly mastered it. When he opened his eyes, it was as if flames danced within them. Now, he had truly become the monarch who commanded fire.
"Ah… hot… so hot…"
Kairen slapped at the flames behind him.
The power of a grand jutsu was boundless—it could shock hundreds, but often harmed the caster a thousandfold.
"Wind Release: Pressure Harm!"
From within the thick smoke, a massive Wind Release technique blasted forth, quickly scattering the haze. Kairen's figure flickered as he dodged Meimuda's jutsu.
With the smoke dispersed by wind, Meimuda and his men emerged.
Kairen looked at the battlefield—his massive area-of-effect Fire Release had already burned to death at least thirty Sunagakure shinobi. About a hundred still remained.
Tsunade crossed her arms, staring coldly at the remaining Sunagakure ninja. Her aura steadily climbed—she was about to join the battle.
"Tsunade! Let me handle this."
Kairen extended his hand to stop her. Under her puzzled gaze, he strode forward.
His white robes fluttered back under the scorching fire winds, revealing his toned upper body.
Meimuda's eyes darkened.
"Brat, not running anymore?"
Kairen formed the Tiger Seal with both hands and spoke softly:
"Sunagakure… do you know the distance between Heaven and Earth?"
"Brat!!"
"You who crawl and gnaw in the sand can never see the clouds above!"
In an instant, Kairen opened Four of the Eight Gates, stacked with the Nine-Tails' chakra. An endless torrent of chakra surged from his body.
Meimuda, staring at the monstrous aura, clenched his teeth hard.
"How can someone like this exist? We've been hunting him with hundreds, yet his chakra hasn't diminished at all. Not even a jinchūriki is this terrifying!"
Kairen's chakra poured into the burning forest. The flames responded, all of them converging like countless fire dragons rising into the sky.
"What is that?!"
Sunagakure ninja below watched in confusion. Why were all the flames gathering together?
It looked as though someone was up to something big!
Meimuda felt unease rise in his chest. That anomaly in the flames had to be the work of that damn brat. He began preparing a large-scale Fire Release.
Gradually, the forest fire condensed under the pull of chakra into an enormous fireball.
The fireball was boundless, as if covering the entire sky. Darkness fell, and heavy clouds gathered all around.
"This… this is a Forbidden Jutsu…"
Several experienced Sunagakure Jōnin muttered. A ninjutsu capable of altering the heavens was unmistakably a Forbidden Jutsu.
Kairen's Blazing Flame Dragon was indeed a Forbidden Jutsu, but with many conditions. Like Kirin, it required terrain advantage—in this case, forest fire.
That was why the development card used was a High-Level Ninjutsu Card, not a Forbidden Jutsu Development Card.
Kairen clapped his hands together and shouted:
"Fire Release: Blazing Flame Dragon!"
The giant fireball in the sky shifted instantly.
"Rooaar—"
The low roar of an azure dragon echoed out. In their sight, a colossal dragon head of fire emerged, bellowing its fury at the world.
Head like a camel, horns like a deer, eyes like a rabbit, ears like an ox…
This giant fire dragon blazed with fierce flames. Compared to the head of a Great Fire Annihilation dragon, it was far more vivid and alive. In its massive dragon eyes burned the light of wrath.
At last, the dragon's body fully condensed—three hundred meters long, vast as a meteor falling from the sky.
...
Several kilometers away, Yūhi Shinku led a squad of flak-jacketed civilian shinobi rushing toward the forest.
They were all ninja Tsunade had once saved. Hearing she was in danger, they came running.
Suddenly, everyone froze. They gawked at the gigantic fire dragon ahead, its roar shaking the heavens, as if stirring the world itself into uproar.
A shinobi muttered blankly:
"This… this, what kind of ninjutsu is this?"
Yūhi Shinku's eyes locked on the blazing dragon.
"This flame, this form transformation, this Fire Release—it can't even be called Fire Release. It's a Forbidden Jutsu. Just who cast this?"
Yūhi Shinku's mind suddenly jumped to Kairen.
"Him?!"
Kairen's hand ignited in flame. He swung it down sharply.
"Blazing Flame Dragon: Release!"
After unleashing the Blazing Flame Dragon, Kairen drew his blade, restored his state, and immediately dashed toward Tsunade. Grabbing her, he used Body Flicker to escape the dragon's blast radius.
This was a suicidal technique—if the caster didn't escape in time, they too would be consumed.
"Rooaaar—"
The dragon roared skyward, then dove with the wind. Its searing heat scorched the forest below.
Meimuda's face twisted in horror.
"Run! Run! Get as far away as possible! Don't stay here!"
"Roaaar—"
But it was too late. The dragon's blazing heat reduced all nearby trees to ash. Then it descended again.
A sweep of flame, and in an instant, a dozen Sunagakure ninja were engulfed and turned to ash.
Several Jōnin used Body Flicker to flee, but the dragon struck down swiftly—within mere dozens of meters, they too were swallowed by the inferno.
Kairen and Tsunade escaped the forest, standing atop a giant tree tens of meters tall, watching the scene ahead.
"BOOM! BOOM! BOOM! BOOM! BOOM—"
The fire dragon exploded violently upon the ground, like a tidal wave crashing down from the heavens, flooding everything in its path.
Burning—unceasing burning—furious burning.
Even thousands of meters away, the blistering heat waves rolled outward, gently stirring Kairen's black hair.
From this day forth, Fire Release would no longer be dismissed as a jutsu that couldn't kill.
But first… let me admire the ravine I'm holding against my chest!
