The owners of the three streaks of white light were Ning Feng—who had used Lightning Cutter, along with Uchiha Shisui and Uchiha Itachi, who had infused their attacks with Lightning Release nature transformation.
When the three landed beside the tiger demon, its face twisted in agony. Amid a piercing, miserable howl, it collapsed to the ground with a heavy thud. In the next moment, its body dissolved into dense demonic qi and scattered away—
as if the tiger demon had never existed at all.
"That beast was strong. If we hadn't killed it instantly, dragging the fight out would've cost us some effort,"
Uchiha Shisui commented.
As a battle-loving ninja, he genuinely enjoyed the thrill of combat.
"Yeah. It's completely different from the beasts we've encountered before. Strictly speaking, it's not even a ninja beast anymore—more like an even stronger, evil immortal beast,"
Uchiha Itachi said after a brief frown.
At the mention of "evil immortal beast," Ning Feng's brows knit slightly. With the advent of Naruto Online, it seemed the entire world had entered a phase of spiritual energy revival—and these tiger demons were likely one of the consequences.
While Ning Feng was thinking, the demonic qi at the spot where the tiger demon died began to gather again, condensing into something similar to the demon cores left behind by the giant cat demons earlier—only this one was far larger.
"This thing seems to contain an enormous amount of chakra. Feng, hurry and keep it,"
Itachi said as he picked up a huge demon core and handed it to Ning Feng.
"An enormous amount of chakra…?"
Ning Feng nodded slightly. It seemed killing these demon beasts brought tremendous benefits.
Coincidentally, he had already obtained the Akimichi Clan's Advanced Secret Medicine, which allowed chakra to be stored by consuming food.
If these demon cores could be eaten… wouldn't that mean he could quickly increase his chakra upper limit!?
With that thought, Ning Feng swallowed the tiger demon's core in one gulp.
He had expected it to taste awful—but the moment it entered his mouth, the core melted like ice crystals at his throat.
Crack—crackle—pop!
A series of sounds rang out as Ning Feng, whose body already brimmed with explosive power, felt a mighty force rapidly scour and refine him.
The muscles in his arms and thighs bulged visibly. His height shot up from around 1.7 meters to a full 1.8 meters in moments.
From afar, he looked like an immovable, mountain-like warrior.
"T-This is an Akimichi clan secret art!?"
"Storing chakra by consuming food!?"
Uchiha Itachi and Uchiha Shisui were stunned.
While the Uchiha clan's secret medicines rivaled those of the Senju, other Konoha clans also had their own specialties—especially the Akimichi, whose chakra-storage method was downright terrifying.
Short battles were one thing, but in prolonged combat, this technique alone allowed the Akimichi to outlast nearly anyone.
Not to mention their Butterfly Mode.
This was Ning Feng's first time truly experiencing how terrifying the Akimichi clan could be.
He could clearly feel that a single punch from him now carried several times the power it had before. Though still not on Tsunade's level, it was nonetheless frightening.
"To pull up mountains with bare hands" wouldn't be an exaggeration.
And this was after swallowing just one tiger demon core.
If he consumed all the cores from the giant mountain cats… that would be insane.
As he was thinking, the excited Uchiha Shisui and Itachi had already snatched the remaining demon cores from the students' hands.
"My foolish little brother, hurry up and eat all these cores,"
Shisui teased. "Your brilliant brothers want to see just how far you can go."
Itachi stood to the side as well, his face full of anticipation.
They didn't bother asking how Ning Feng had obtained Akimichi techniques. All they cared about was whether their little brother could grow stronger—fast.
To them, nurturing a monster even more monstrous than a genius was far more satisfying than being geniuses themselves.
Ning Feng laughed and didn't stand on ceremony, swallowing all the remaining demon cores formed from the slain mountain cats.
The effects were similar to the tiger demon's core. His limb muscles became even more explosive, brimming with power, and his height climbed from 1.8 meters to a full 1.9 meters!
He'd been a little worried that eating so many cores might turn him into a greasy fatty like many Akimichi clan members.
But to his surprise, the cores only caused his muscles to swell with strength—he didn't gain any fat at all.
Already handsome to begin with, Ning Feng now exuded overwhelming masculine charm.
The kind of charm born purely of power.
From afar, several of the female classmates couldn't help screaming and gasping at the sight of him.
Some even tried to step forward to touch his muscles—only to be stopped cold by Liu Yue, who shot them a vicious glare.
"I never thought the Akimichi clan's secret arts would be this terrifying,"
Shisui sighed in amazement.
Itachi quickly added, "Little brother, try throwing a punch—aim at that tree over there."
Ning Feng nodded, took a deep breath, and punched forward.
The result—
The tree was instantly reduced to powder.
The violent shockwave didn't even stop there, smashing several trees behind it as well.
And this was without using any taijutsu technique.
Ning Feng roughly estimated the punch carried at least five to six thousand jin of force. Against something like Sasori's puppets, it would be one punch per puppet.
"Looks like it's time to teach you Uchiha taijutsu,"
Itachi said, stroking his chin with a satisfied expression.
"Hmph. If Feng's learning something next, it should be my Body Flicker Technique!"
Shisui cut in. "Body Flicker paired with this terrifying punching power—shaking the entire ninja world is just a matter of time!"
"With Flying Thunder God already mastered, why bother learning your Body Flicker?"
Itachi shot Shisui a glare.
"I don't care—Feng is my little brother too!"
"You're just a cousin, not his real brother. Strictly speaking, I'm his brother!"
"Hmph! A cousin is still a brother! What, got a problem!?"
The two puffed out their chests, eyes glowing green as if they wanted to sculpt Ning Feng into a masterpiece of the ninja world.
Looking at his two brothers—both utterly devoted to him—Ning Feng didn't know whether to laugh or cry.
All he knew was this—
having two brother-obsessed older brothers felt incredibly good.
