Goku powered up a Kamehameha while Vegeta hit him with a rapid Galick Gun. Their blast exploded before they appeared in front of each other and went all out.
Every punch was blocked with a matching punch, and every kick was blocked with an identical kick. It was like watching someone fight a mirror image of themself.
Vegeta lowered his hand with a chopping motion towards Goku's neck while Goku blocked it with the opposing hand.
The pure hearted Saiyan knee kicked at Vegeta's gut while Vegeta blocked it with his opposing knee.
They then caught each other's hands and started powering up, pushing against each other in a test of strength.
The ground cracked around them, mountains of dirt and stone shot up while a crater formed at their feet, the space around them bent and wobbled like a black hole was forming, and then they head-butted each other.
A massive explosion erupted from the point of impact. Ki so powerful and long-lasting shot into the skies above and formed stars and physical mater. Countless super nova exploded above the heads of everyone still training in this place.
Krillin looked around with a sheer look of awe, hoping that he soon would catch up to his friends. The other Z-Fighters did the same, all except Broly, who was still in a state deep meditation.
Vegeta performed a jump kick towards Goku's chest while the pure hearted Saiyan grabbed his leg and tossed him around in circles.
The Saiyan King quickly rotated before throwing his opponent and launching a beam of energy towards him.
Goku created a Ki blast in his hand and used it to deflect Vegeta's attack, sending both the beams into the depths of the endless terrain of their training realm.
When it detonated into a super nova, the two were once again in close rage.
Vegeta punched at Goku's face.
Goku dodged and kicked at Vegeta's neck.
The Saiyan King leaned forward and took the blow while punching Goku in the gut, sending him flying into the distance.
Goku shot out a solar flare without even making the pose while teleporting behind Vegeta and drop kicking his shoulder.
The Saiyan King took the blow again, but reached his arm around his back and fired a blast that created a supernova that shot into the sky.
Goku took the brunt of the attack, back flipping until he landed a bit away and shot out a Spiral Kamehameha towards his opponent.
Vegeta smirked and teleported behind Goku and hit him with a point-blank Galick Kamehameha.
The massive blast sent Goku flying into the distance. He landed against the ground and hopped back onto his feet while a thin but incredible durable layer of Divine-Ki surrounded his body.
His shirt was on fire, but that was no other noticeable damage.
Goku tore his shirt of and powered up even more. Several dozen orbs of the Saiyan Immortal's Ki appeared around his body as he pointed them all towards Vegeta and shot out with them.
"Kamehameha; Hundred Spiral Formation," The pure hearted Saiyan's voice was calm as the beams shot out turning into a giant drill of energy that threatened to end Vegeta's existence.
The King didn't back down. With a calm expression, he closed his eyes and roared as a giant muscular avatar of an Oozaru appeared around his body. The roar alone was enough to dissipate the energy from Goku's attack. However, it also created cracks and tears in the space around them.
"It's like Armageddon!" Tien spoke up.
"Incredible," Krillin smiled.
"It really is," Yamcha agreed.
"Then we shouldn't fall behind too much! If they can learn those techniques, then we can learn them too!" Piccolo informed everyone before he thought what needed to be done to take him to the next plateau of power.
"Right! We basically have eternity on our side. I know I can do something to catch up to Goku!" Krillin clenched his fists tightly.
Goku smirked as an Avatar of his physical form appeared around him. He stood across from his rival with a bright smile on his face.
"No more holding back?!"
"I haven't even gotten started yet," Vegeta laughed as stood in his martial stance.
The two charged each other and the battle of giants began. Vegeta's movements were more chaotic, less predictable, while Goku's form was the epitome of order and control. The pure hearted Saiyan's movements were fluid and ever changing.
A flurry of blows was dodged while Goku tried to counter.
Vegeta saw his opponent's fist coming for his face and leaned in before powering up a Ki blast with his mouth.
Goku jumped over the Ki blast and reached out for Vegeta's neck to land a grappling chokehold. However, Vegeta ducked down and tried to spin around with his elbow ready to penetrate his opponent's side.
The pure hearted Saiyan blocked the attack while trying to punch straight into Vegeta's gut.
The Saiyan King expanded a wave of Destruction Ki around his body like a shell, tearing away at the space around him like a black hole.
The barrier forced Goku's Avatar to back off. However, it wasn't without cost. The avatar's arm was gone.
Goku didn't seem bothered by the missing limb at all. In fact, he smiled and snapped his fingers, causing the arm to explode with such incredible force that it penetrated the barrier of destruction and ripped the upper half of the Oozaru Avatar into pieces.
Vegeta started laughing as the Avatar disappeared, "Is that your best, Kakarot?"
"I'm just getting warmed up," Goku replied while his Avatar faded.
The two started walking towards each other and stopped at arms-length.
Beerus' eyes darted around rapidly when Krillin landed beside Whis.
"What's going on, they're just standing there,"
"Oh, they are moving much faster than you can see. Don't look, Krillin, feel," Whis informed.
Krillin nodded his head and saw the fight with his mind's eye. Their attacks were faster than light itself, yet their Ki kept their fight from disturbing their surroundings. To those not on their level, they appeared to be staring each other down, but to those that could perceive the battle, it was almost like a dance of various martial arts.
Whis smiled happily as he enjoyed the fight. They were close to equal in strength, but he knew what was about to happen. The longer the battle carried on, the more evident it became who the victor would be.
Their stance suddenly changed as Goku's face leaned to the side and Vegeta's fists destroyed the terrain behind the pure-hearted Saiyan's back.
Once again, their body returned to their standing position with Goku only sporting a bruise on his cheek.
The image broke once again as Goku took a knee to the stomach. The current from Vegeta's kick was strong enough to send up tons of debris into the endless sky above.
Goku grit his teeth and once again began their invisible exchange.
Another interruption appeared while Vegeta's fist twisted into Goku's stomach.
It continued for several more hours until Goku suddenly hit Vegeta into the air.
"It seems, Goku's body has finally adjusted and caught up," Whis smiled.
The two suddenly fired their most powerful attacks.
"Giga Drill Kamehameha!" Goku shouted as millions of glowing blue spheres surrounded him and shot towards Vegeta, forming into one giant drill shaped laser.
Author Note: MY DRILL IS THE DRILL THAT WILL PEIRCE THE HEAVENS!
Vegeta held his hands out to his side and powered up a sphere of black energy and a sphere of white energy. He then slammed them together and shouted, "Final Flare Ultima!"
The beam of black and white energy shot at Goku's attack and clashed, stopping halfway while they both pushed all their energy into their Ki beams, locking them in a beam struggle.
Due to Vegeta's magical spell empowering his beam, it started to slowly push back and win against the Giga Drill Kamehameha.
"Kaio-Ken Times Two!!!" A red aura engulfed Goku's body.
"Kokoro-Ken Times Two!!!" A blue aura engulfed Vegeta's body.
The two then kept trying to one up the other and continued to raise the multiplier until they each reached a 1,000. The sheer energy spewing from their beam struggle created countless stars that shot away from the ground at light speed.
The dimension cracked and shattered around the center of their struggle, shaking everything in reality while it tried to repair itself and grow stronger.
When the Timeless Training Grounds adapted and evolved to stabilize itself, the Ki beams exploded. Whis put up a shield to contain the blast but the force from it rocked the endless realm until it nearly collapsed.
When the explosion died down, Vegeta had his fist running through his opponent's chest while Goku had his fist impaled inside the King's stomach.
The two then backed off and healed while growing even stronger in the process.
Then something happened that made the Z-Fighters jaw drop. The two charged in and started tearing into each other.
Vegeta's punch cleaved off a portion of Goku's stomach.
Goku's kick tore through half of Vegeta's face, exposing his skull and liquefying his eye.
Vegeta snapped Goku's arm back with an elbow that nearly severed it the goofy Saiyan's limb completely off. It was only hanging on by a single strip of flesh.
However, due to becoming Immortals, their ability to regenerate was off the charts. It was almost on the same level as a Namekian. However, whereas a Namekian can survive having his head cut off, the Saiyans could not.
Their limbs, bones, muscles, and flesh all repaired itself quickly while their powers continued to soar. With healing spells and Goku's ability to absorb the ambient energy of the universe to repair his wounds, the fight looked like it would never stop.
It only became more and more brutal and bloody the longer it continued.
Before they knew it, three years had passed inside the Timeless Training Grounds. Their powers were still soaring like crazy, and it was becoming clear the fight would never end unless one of them decided to go for the kill.
Just as their attacks were about to connect, they were interrupted by a sudden explosion of lightning in which the likes they've only seen when Kibo ascended to a higher form of godhood.
On the horizon, spiraling bolts of jade colored lightning shot down at the ground. Each bolt was shaped in the appearance of eastern dragons, and the force was so intense that it caused Goku and Vegeta to stop their fight.
100 bolts later, a terrifying jade green energy shot into the sky. The realm quaked and shivered as the body of Broly rose higher and higher into it.
"Ah, now this is what Immortal Ki is supposed to feel like in a Saiyan," Whis grinned as he saw the newest Saiyan rise to power.
His fur was a lustrous jade green color that glowed brightly. His Hair was in his Super Saiyan State, and his eyes looked like glowing neon emeralds with a pitch-black pupil in their centers.
"The hell is that form. It's nothing like the dark green color of TSSG-Green," Vegeta crossed his arms.
"This power is incredible! It's actually stronger than us right now!" Goku's eyes sparkled.
"Dibs!" Vegeta flew off.
Goku's shoulders dropped as he cried out, "Aww…come on! I trained him!"
"Exactly, you've fought him plenty enough already!" Vegeta shouted back.
Broly was staring at himself in awe. He couldn't believe the sheer power overflowing from his Ki-Center. It wasn't stopping and continued to rise rapidly at a rate Goku and Vegeta would grow to feel a bit jealous over.
"I think I get it," Krillin spoke up.
Whis lifted a brow, "Ooh, please enlighten us. I'm curious as to what you think."
"Well, destruction energy is so powerful because it's a fundamental law of our universe, but what if Ki could take on other properties from different laws. I think that green energy represents infinity. Broly's mutation allows him to channel that law into his body and convert it into pure Ki."
"Immortal Ki, it is a great deal stronger than regular Ki and weaker than Godly Ki by almost half. But other than that, I think your assessment is correct."
"Then what's stopping us from finding our own laws to instill into our Ki?" Krillin looked as if he just figured something out.
Whis chuckled as he thought, "It appears there may be a second coming of Buddha. Perhaps I should lead him to Gautama's inheritance site. It would be funny to see Beerus' expression."
