### Chapter 4: Katon · Gōka Mekkyaku! A Sea of Fire Destroying Heaven and Earth!
The Grade 2 Cursed Spirit stood as tall as three people.
Its silhouette resembled a radish, with limbs growing from its sides.
Its face was almost human, yet abnormally large, occupying half of its front. Furthermore, the top of its head also bore a skull-like face.
However, neither Mei Mei nor Iori Utahime paid any attention to the Cursed Spirit frantically fleeing. They focused all their attention on Ryota, who stood not far away.
Mei Mei guessed that Utahime, who wasn't lacking in intelligence, had quickly made the connection as well.
Although they didn't know what methods Ryota had used before, this attack would undoubtedly reveal something more.
They could see if any traces of Cursed Energy appeared.
The two women's small movements naturally didn't escape Ryota's eyes.
But he didn't care about such things.
Moreover, there was a world of difference between Cursed Energy and Chakra.
Ryota slowly raised his hands, and Mei Mei and Utahime's eyes followed his movements closely.
*Clap!*
Ryota's fingers interlaced, pressing together.
He formed a hand seal in front of his chest.
**[Horse]**
"*Katon*—"
Ryota spoke with an indifferent expression, the Chakra inside his body boiling frantically.
"*Gōka Mekkyaku*!" (Great Fire Annihilation)
Under the shocked gazes of Mei Mei and Utahime.
A stream of scorching flame, only as thick as a tree branch, spewed from Ryota's mouth.
Then, in the blink of an eye, the flame surged violently, instantly expanding into a firestorm as vast as a sea.
The turbulent waves of fire radiated rolling heat, blowing the two women's hair back against their foreheads.
Sweat poured down their fair cheeks from the heat.
Neither of them used Cursed Energy to defend themselves.
Or perhaps, the shocking scene caused them both to forget to use Cursed Energy to resist the high-temperature airwaves brought by the Great Fire Annihilation!
Mei Mei and Utahime's vision was completely occupied by the monstrous wave of fire.
They watched helplessly as the massive wave of flames, spanning tens of meters, engulfed everything in its path.
Even the forest the Cursed Spirit had rushed into was swallowed up by the rolling scorching flames, as if devoured by a prehistoric beast.
A few seconds later, the flames that had turned the surroundings into a sea of fire ceased pouring from Ryota's mouth.
However, everything in front of Ryota had transformed into a different scene.
Desolate, silent, tragic.
The originally lush lawn had been burned to ash, and the fertile soil was reduced to cracked, scorched earth where nothing could grow.
Further away, the forest the Grade 2 Cursed Spirit had run into...
Under the monstrous waves of fire, it had also become a lifeless land of charcoal.
Trees that were once lush and tall were all burned to charcoal, snapping and falling to the ground with crisp *cracks*, completely unrecognizable.
The fleeing Grade 2 Cursed Spirit within the forest was entirely charred black.
It maintained the terrified expression on its face and its running posture, frozen in place.
Under the *Gōka Mekkyaku* that turned all creation to ash, its life force was completely extinguished.
*Whoosh...*
A breeze blew past.
The Grade 2 Cursed Spirit instantly turned into dust and scattered with the wind, ceasing to exist.
"Not bad."
Ryota nodded slightly, satisfied with the scene caused by his first use of *Ninjutsu*.
Although he hadn't reached Uchiha Madara's complete strength, and the inheritance rate was only 35%.
However, simply using a B-rank *Ninjutsu*, he was able to produce an effect almost capable of destroying heaven and earth, just like Uchiha Madara during the Fourth Great Ninja War.
If he increased the Chakra output, the power could reach an even higher level.
Seeing it on a TV screen was indeed not as visceral as experiencing it firsthand.
At the same time, Ryota's understanding of Uchiha Madara's strength became deeper.
He also looked forward to obtaining more powerful forces like *Mokuton* (Wood Release), the Sage Body, the Eternal Mangekyou, and the Rinnegan as his inheritance rate increased.
**[Ding! Congratulations Master on killing a Grade 2 Cursed Spirit. Inheritance rate increased by 0.1%]**
**[Detected increase in Master's inheritance rate. Unlocking Sub-panel: Tailed Beast Panel]**
**[Note: Character Template inheritance requires killing Cursed Spirits to obtain, but leveling up the Tailed Beast Panel can be done by killing any target possessing Cursed Energy.]**
**[Note: The Tailed Beast Panel has been modified by the System for world adaptability. Tailed Beast power characteristics possess both Cursed Energy and Chakra.]**
"Oh?"
A flicker of surprise flashed in Ryota's eyes.
The characteristics of the Tailed Beast power aren't just Chakra?
However, he wasn't in a hurry to sort through this information.
He would find a place to eat first, then organize the System's information; it wouldn't be too late to plan his future actions then.
At the very least, now that he possessed this strength, nothing below Special Grade could pose a threat to him.
It could be said that Ryota now had quite a lot of leeway.
Ryota's Three-Tomoe Sharingan spun as he looked at Mei Mei and Utahime, who had yet to recover their senses, finding it amusing.
"What, stunned by such a small scene?"
