Lightning Ball Shuriken Technique was originally a cooperative Ninjutsu that Uzumaki Boruto and Uchiha Sarada created in the original "Boruto: Naruto Next Generations" anime series.
To perform this technique, they needed each other's help.
Sarada would release Lightning Release: Lightning Ball to cast 5 crackling lightning spheres, and Boruto would throw lightning-infused shurikens at them.
This way, when the lightning balls and the shurikens came in contact, they would be combined before charging towards their enemy at a breakneck speed.
This combination Ninjutsu wouldn't just electrocute the enemy, but the shurikens inside the lightning balls would also pierce through an unsuspecting person's chakra coating, skin, flesh, and even bones before electrocuting their internal organs.
However, Seimei didn't need two people to cast this improvised technique. He alone was enough.
Since Boruto and Sarada wouldn't be born in this world for at least 60 more years, he could only shamelessly copy this technique.
After all, this was a useful technique, at least for the current him.
Back in the battle…
As Tobirama watched the lightning ball shurikens racing toward him, he immediately analyzed the lethality of this technique.
So, he quickly activated Water Release: Instant Water.
Waves of water came out of his feet like water jets, helping him get away from the deadly projectiles' trajectory by a hair's breadth.
While dodging the lightning ball shurikens, he thought…
That shadow clone had 60% of Seimei's total chakra reserves.
That's why it even fooled me by making me think that it was the real Seimei.
Unlike the usual clone techniques, such as earth clone and water clone, all unused chakra of a shadow clone always goes back to the caster once it gets dispersed.
As such, the caster of the Shadow Clone Technique doesn't have to worry about wasting the chakra even if the clones are dispersed or destroyed without achieving anything.
Plus, the caster will get all the memories and experiences of the clone.
So, even if Seimei pours 80% of his total chakra reserves into his shadow clone, once the clone disperses, he will get the majority of the clone's unused chakra.
A clever trick indeed.
I never thought I would be tricked by the very technique I invented.
On the other side, Seimei saw Tobirama dodging his attack.
Not wanting to let Tobirama get away so easily, He quickly formed a series of hand seals.
Once he formed the final hand seal, he released a large amount of Water Release chakra that condensed into a 16-meter-long serpentine water dragon.
Water Release: Water Dragon Bullet Technique
ROAR~ Roaaaaaaaar~
The water dragon opened its mouth, let out a deafening roar, and charged toward Tobirama, ready to devour him.
Seeing the water dragon coming toward him at full force, Tobirama didn't panic at all.
Instead, he let out a barely perceptible smirk and thought.
Oh! Now, you've become brave enough to launch a Water Release Ninjutsu at me, my son?
Heh!
Let me show you what a true Water Release Ninjutsu actually looks like.
Although Tobirama let his thoughts wander, his hands never stopped.
He immediately formed three hand seals.
Soon, the water particles in the atmosphere started to respond to his Water Release chakra, creating a swirl of water around him.
Water Release: Torrent Bullet
The swirling water quickly formed a 4-meter-wide, rapidly rotating, horizontal vortex, which quickly moved toward Seimei's water dragon at the speed of a bullet.
The two Ninjutsu collided head-on and were in a stalemate for a moment before the horizontal water vortex smashed the water dragon's mouth.
Next, the vortex destroyed the internal structure of the Water Dragon Bullet Technique with its powerful rotational force and charging speed, effectively reducing the dragon into nothing but a few splashes of water.
It even used the Water Release chakra from the water dragon to empower itself before heading straight at Seimei.
Seeing the deadly water twister heading toward him, he decisively activated the Body Flicker Technique and moved out of its way.
BOOOOOOOM!
While retreating, he saw the horizontal water vortex hitting his previous location, causing several spider-web-like cracks to form within a 20-meter radius of the impact zone.
The sheer force of the impact caused dust, water, and huge chunks of rock to fly into the air.
And the churning water of the Ninjutsu even absorbed several sharp rock fragments into the vortex, drilling into the ground until the Ninjutsu lost its power.
After watching this devastation, Seimei couldn't help but curse himself in his mind.
Seimei, oh Seimei…when did you become such an idiot?
Why the hell did you have to tempt fate and use a Water Release technique against this man, whose mastery over Water Release is even higher than Mizukage's?
Isn't it literally playing with fire…uh…or water in this case?
It's simply asking for a beating!
No! No!
This can't go on.
If I suddenly become so courageous in this deadly world, won't I just die faster?
I was careless just now. But no more.
Let's end this.
At this moment, Seimei saw Tobirama dashing toward him. His father was obviously trying to close the distance between them, engage in close combat, and end this fight quickly.
But Seimei couldn't let this happen. At least, not so easily.
So, he quickly formed three single-handed hand seals that condensed a vast amount of howling Wind Release chakra in his right hand.
Wind Release: Beast Tearing Gale Palm
The Wind Release chakra created a 40-meter-long greenish-blue demonic claw of wind filled with sharp wind in front of Seimei, which he could control with his right hand.
Seimei wasted no time and slashed this demonic claw of wind toward the incoming Tobirama, who also gathered a massive amount of chakra in his right hand without slowing down.
Just as the demonic wind claw arrived in front of him, Tobirama also threw a punch.
Chakra Enhanced Strength
The moment Tobirama's right fist and the demonic claw made contact, the chakra gathered in the fist immediately detonated with full force.
BOOOOOOOM~
The two techniques dispersed each other with a loud explosion of chakra, creating visible shockwaves.
Tobirama was about to continue charging toward Seimei when he saw him retrieving two 3-feet-wide, giant fuma shurikens from his storage bracelet and charging them with lightning chakra.
Then, he saw Seimei jumping into the air and launching the fuma shurikens at him in a jiffy.
These lightning-infused fuma shurikens targeted his left abdomen and right lung, giving him no time to move to either side.
So, Tobirama could only jump high to avoid the deadly blades of these sharp, lightning-infused giant shurikens.
The moment these shurikens passed below Tobirama, Seimei activated his Sharingan and moved both of his hands in the air.
Surprisingly, the shurikens changed their trajectory and hit each other, causing one fuma shuriken to take a sharp turn and head directly toward the now airborne Tobirama.
Tobirama quickly understood what happened here.
It's the Uchiha-style Shurikenjutsu.
He is holding those barely visible steel wires to control the fuma shurikens' trajectory mid-air.
He made those shurikens hit each other with perfect accuracy, causing one fuma shuriken to be deflected toward my direction.
Smart!
But it won't be enough, my boy!
Wind Release: Gale Palm
With this thought, Tobirama, who was airborne, cast the C-rank Gale Palm jutsu without hand seals and released a stream of high-speed air from his palms.
The jet of air released from his palm helped him change his direction mid-air and land safely on the ground, causing the fuma shuriken to miss.
Watching this, Seimei smirked and quickly disappeared with a puff of smoke.
Tobirama watched this scene with confusion, but his mind was working at high speed.
Hmm??
Another shadow clone?
And this one even had nearly 80% of his original chakra reserves.
So, I was fooled again?
If this is a shadow clone, then where is Sei…?
Before he could finish his thoughts, he sensed an enormous amount of chakra radiating from the redirected fuma shuriken he just dodged.
Before he could even turn his head back, the airborne fuma shuriken transformed into Seimei, who quickly formed a series of hand seals within less than a quarter of a second.
Chirp~ Chirp~ Chirp~ Crackle~
A huge amount of lightning chakra quickly condensed into Seimei's right palm, discharging countless arcs of menacing, blue lightning bolts.
Yes!
This was the real Seimei.
He first created a shadow clone by transferring nearly 95% of his remaining chakra before using the Transformation Jutsu to turn himself into a fake fuma shuriken.
As a result, the real Seimei, who turned into a fuma shuriken, had a very small amount of chakra.
That was why Tobirama was fooled once again.
After all, who would be mad enough to pour almost all their chakra into a clone, even if it was a shadow clone?
If discovered before the clone could dispel itself, Seimei could be in fatal danger, as he had little chakra to spare.
And that was exactly why this gamble paid off.
Even the famed inventor of Ninjutsu, Senju Tobirama, could hardly think of doing something so outrageous.
As for the little chakra the real Seimei (fuma shuriken Seimei) still had, he had his clone mask it by infusing both fuma shuriken with a lot of lightning chakra.
The meticulous planning worked. And now, Seimei had a real shot at giving his father a scare.
Lightning Release: Chidori Sharp Spear
Seimei, who was still in the air, pointed his right hand toward Tobirama.
The dense lightning chakra gathered in his hand turned into a straight spear of lightning with formidable cutting power and extended towards Tobirama, aiming to pierce through his right shoulder.
Tobirama felt his hair standing on end as he quickly tried to move away.
But he was still a little slow.
Although the spear of lightning couldn't pierce through his shoulder, it still slashed the upper part of his shoulder, causing him to bleed from that spot.
This caused Tobirama to instinctively release his Super Kage-level chakra and detonate it around his body.
Boooooom~
The chakra detonation created a huge shockwave that caused the spear of lightning to crumble.
Seimei's eyes widened.
He could only mutter "Oh shit!", before he was blasted away by the shockwave and landed at least 70 meters away with a thud.
Thud~
Upon hearing this sound, Tobirama looked toward the place Seimei had landed, and he had only one thought in his mind.
Oh no! I messed up!!!!!!
Tobirama quickly controlled his raging chakra and flickered toward Seimei.
Seimei, who was lying on the ground like a dead fish, turned his face to his father and said while groaning in pain, "Ouch! You're really merciless, Father!"
"My soul almost ascended to the Pure Land."
Tobirama watched this scene and sighed in relief.
If Seimei could joke like this, it meant he was relatively fine. Yeah, relatively!
Tobirama let out an embarrassed cough and replied, "That was an accident."
"I didn't expect your attack to reach me so suddenly."
Seimei could only laugh, "Hehe!"
"So, did I pass?"
Tobirama smiled and replied, "You did. And you did wonderfully, my son."
"I'm proud of you."
Hearing this, Seimei slowly closed his eyes and let out a tired yet satisfied sigh.
He opened his eyes again and said, "Then…"
"I will leave the rest to you."
With that, Seimei fainted.
Tobirama didn't say anything.
He wordlessly picked Seimei up and carried him on his back.
"No problem. Rest now!"
As soon as the word fell, Tobirama activated the Flying Thunder God Technique and disappeared from the training ground along with Seimei.
