"Eight Inner Chakra Enlightenment?!"
Guy tilts his head in confusion.
"Mmm… the Eight Inner Chakra Enlightenment is an extremely powerful technique to harmonize mind, body, spirit, and chakra to exert strength far beyond the normal abilities of a human.
Unlike the Eight Inner gate formations, this technique permanently opens the chakra nodes in the body and maintains the harmony of both chakra and spirit within those chakra nodes. This harmony of chakra, spirit, and life energy generates a unique and more potent energy called Aura. A human can use this aura to perform physical feats far beyond the reach of a normal shinobi."
Chen points a finger toward Guy. He infuses a tiny bit of his cyan aura at the tip of his finger and smashes it toward the ground.
Bang…
Chen pauses his finger an inch above the ground.
Rumble… rumble…
The ground beneath Chen's feet cracks open and a ten-meter-wide rift split open the ground.
"The aura is not just the control of physical strength and spiritual energy. It's the control of the very laws of nature: the transfer and conversion of kinetic and potential energy." Chen explains the essence of aura to Guy.
"If you can master this, then you will truly become the most powerful Taijutsu expert in this world."
Sigh…
Chen sighs and gazes toward the sky.
Gulp…
Guy gulps his saliva as he recalls Izuna's explanation about Aura. Both of them have striking similarities with each other. Though Izuna's explanation has more depth to it. Nonetheless, it was complicated for him to make complete sense.
"T-then master Chen… how many chakra gates did you open?" Guy enquires.
"Sigh…"
Master Chen sighs again and turns towards Guy.
"I wasn't talented enough. I was only able to open four chakra nodes in my lifetime. In this matter, your father Might Dai was much more talented than me. His sixth inner gate was almost on par with my Fourth chakra node and his seventh gate surpassed my Fourth chakra node by quite a bit. As for the eight gates… hehe… let's not talk about it!" Chen chuckles.
Shoom…
Suddenly, Chen's expression turns stiff as a pulse of chakra flashes past his mind.
"Guy… I can't control my body anymore. So, be prepared!"
Whoosh…
A cyan aura envelops Chen's body, and he disappears from Guy's vision.
"He's fast!" Guy swiftly takes a defensive position and closely follows Chen's movements.
Swoosh… Bang…
Chen appears behind Guy and performs a roundhouse kick.
Bang…
The kicks land on Guy and sends him flying across the forest.
Bam…
Guy crashes through multiple trees before smashing into a boulder.
Whoosh…
Chen reappears in front of Guy and opens his mouth.
"That was my afterimage you were tracking!"
Swoosh…
Chen stomps the ground and once again three more Chen appear in Guy's vision.
Bang… bang… bang…
Guy wards off multiple of Chen's constant flurry of attacks with his arms and legs. His hands and legs turn sore from the constant defense.
HAAHH…
Guy crosses his arms and riles up his chakra.
"Eight Inner Gate Formation: Sixth Gate of View: Open,"
Guy emits a powerful shockwave from his body that disperses Chen's afterimages and pushes him back.
Chen crosses his arms in front of his body and glances at Guy.
"So, you can also open the Sixth Gate. Wonderful!"
Whoosh…
The cyan aura around Chen's body thickens, and he performs an upward spin kick. Chen infuses his aura into the kick and generates a powerful wind tornado with the kick.
The tornado morphs into a giant cyan dragon with whiskers.
ROOAAARR…
It releases a powerful roar and leaps toward Guy intending to swallow him.
Guy confronts the giant dragon and releases a flurry of punches.
"Asakujaku,"
A peacock-like fan of flames appears in front of him as Guy's rapid punches set the air ablaze. The flurry of fireballs bombards the cyan dragon. However, it swallows them all and proceeds to attack Guy.
HAAH…
Guy recedes his fists even further and gathers the surrounding aura into his fists.
BANG…
His punch explodes forward a giant fire phoenix erupts from his attack. The phoenix and the dragon clash together and a hurricane of fire and wind appears on the battlefield. Both of their attacks ravage the battlefield around them and multiple Zetsu die as collateral.
Finally, both jutsus cancel out each other and vanish into the air.
Huff… Huff…
Guy breathes heavily with sweat around his body. Exerting such strength and techniques comes at the cost of his stamina.
On the other side, Master Chen is still in his peak state. Being an Edo, he doesn't have to worry about chakra and stamina since he has infinite reserves of them.
The three former Raikages, A, Kakashi, and the rest of the Edo pause and glances at the battle between Chen and Kakashi.
"I didn't expect there is still someone in Konoha who possesses the same level of Taijutsu skill as Master Chen." The Second Raikage and the Third Raikage recognize Master Chen and acknowledge Guy's Taijutsu skills.
They have fought multiple times against this legendary Taijutsu master during the Second and the Third Shinobi war and are aware of his high combat prowess.
At some distance from the battlefield,
Tenten, Lee, and Neji stand on a small hill and gazes toward the giant black cloud.
"Byakugan!"
Shiing…
Neji activates his Byakugan and glances in the direction of the battlefield. He notices the three former Raikage, A, the three bodyguards, Kakashi, Master Chen, and Guy.
"I can see Guy-sensei! He is currently fighting against someone." Neji informs Guy and Tenten.
"Guy Sensei! I will be right there." Lee clenches his fists with a bright flame in his eyes.
"Tenten, how long will it take?" He turns towards Tenten, who is tinkering with some glider-like device.
"Give me a few more minutes. This flying device from the Land of the Sky is a bit broken. I forgot to perform maintenance on it after taking it from those shinobis."
Sigh…
Neji sighs and shakes his head.
"What are we even doing here? We should be retreating behind the back lines! And yet here I am with you two."
"It was Lee's idea!" Tenten adjusts the wings of a glider as he pushes it towards Lee with an angry expression.
Hehe…
Lee sweats at Tenten's expression.
"But… But… Guy sensei is fighting on the battlefield for our sake. How can I sit behind and watch from the back line, even after we have grown strong to such an extent?" Lee makes puppy eyes towards Neji and sticks close to him.
Augh…
"Fine!" Neji is repulsed by Lee's sweat and tears and reluctantly agrees.
"You both owe me thirty thousand Ryō each for these flying devices." Tenten's emotionless voice douses down their enthusiasm.
The trio ties the flying device around their back and jumps down from the hill. They swiftly fly towards the battlefield.
Bzzt…
A small bolt of lightning flies from the black clouds and zaps Lee. Smoke rises from Lee and his glider.
"Lee, are you alright?" Neji asks in worry.
"I… I am fine!" Lee gives a thumbs up with smoke rising from his body.
Back on the battlefield,
Whoosh… swoosh…
Master Chen swiftly flickers in front of Guy and lands a flurry of kicks and punches at him.
"Leaf Great whirlwind,"
Guy helplessly dodges every strike he could and blocks every strike he couldn't.
"Guy!"
Kakashi glances in Guy's direction but is unable to help him as he is held back by enemies on every side.
"Tch…" Guy clicks his tongue.
"Looks like I can't hold back anymore." He sighs and prepares to open the Seventh Gate.
"GUUYYYY SENSEEEIII!!!"
Lee's voice echoes in Guy's ears.
Sniff…
Tears appear in Guy's ears as he clenches his fists.
"I can even hear Lee cheering for me in this battle. Looks like I can't give up. With this battle, I will surpass my limits and set an example for Lee."
Haah…
Guy extends his arms in front of his body and prepares to further rile up his chakra and aura.
"AAAHH… GUY SENSEEIIII!!!"
"W-what?! Even Neji and Tenten are cheering up for me. Now I have to win this battle at all costs."
Tears flood out from Guy's eyes.
Suddenly,
BANG… BANG… BANG…
Three explosions ring in the air.
