The sun rises and sets, spring passes and winter comes.
Soon, a year had passed since Yuujin and Goku began their training atop Korin Tower.
On this day—
Boom! Boom! Boom!
Thunderous sounds echoed above the sea of clouds, as two figures clashed intensely in mid-air.
Surprisingly, they were two identical Yuujin!
Both their appearances and auras were exactly the same, the only difference being that one had the character "Yin" on his forehead, while the other had the character "Yang."
This was a martial art Yuujin developed during his year of training on Korin Tower, called the [Yin-Yang Fist]. When using the [Yin-Yang Fist], Yuujin could split himself into two, manifesting two immortal forms: Yin Yuujin and Yang Yuujin.
The two Yuujin shared a unified mind and soul, yet could act independently, and, more importantly, they possessed the same strength as the original Yuujin!
Although Goku was a decent training partner, she was still too young, and her strength fell far short of Yuujin's. Whenever Yuujin sparred with Goku, it was merely practice in martial arts and techniques rather than a full-strength battle. This prompted Yuujin to consider whether he could create a martial art that would allow him to split himself in two and fight against himself.
Given Yuujin's current martial arts level and experience, creating such a technique was a bit challenging, but with the suggestions and guidance of Karin, he finally developed the [Yin-Yang Fist].
While it was still far inferior to techniques like the [Kaio-ken], there was no doubt that it was a powerful martial art.
Whether it was Yin Yuujin or Yang Yuujin, both possessed the same strength as the original Yuujin. Not only could this technique help identify his weaknesses and improve during sparring, but it was also extremely useful in real combat.
It could be said that the coordinated efforts of Yin Yuujin and Yang Yuujin, who shared a unified mind, could easily unleash a battle power several times greater than the original Yuujin!
Of course, this martial art was not without its drawbacks.
Once the [Yin-Yang Fist] was used, Yuujin's energy would be depleted at double the rate. If the original Yuujin could fight for 100 hours, then after using the [Yin-Yang Fist], he could only last for 50 hours—a simple principle of energy conservation.
However, compared to its advantages, this drawback was insignificant. Even if the duration was halved, what did it matter? As long as he defeated his enemy before his energy was exhausted, that was enough.
If using the [Yin-Yang Fist] still wasn't enough to win, then what's the point of fighting? It would be wiser to flee and save one's life!
Returning to the current situation, Yin Yuujin and Yang Yuujin were still fiercely battling above the sea of clouds, each clash causing a massive depression in the cloud layer.
Fighting against each other felt like fighting against oneself. With identical strength, Yin Yuujin and Yang Yuujin were evenly matched, with no clear victor.
In such a scenario, the only way to win was to break one's limits during the fight—only then could there be a chance of defeating the opponent!
With a bang, the two clashed again and then withdrew, creating some distance.
"Aaahhhhhh!!!!"
Their hands moved like wheels, as Yin Yuujin and Yang Yuujin launched hundreds of energy blasts at each other, turning the sea of clouds into a scene of explosions.
On Planet Vegeta, to fire such powerful energy blasts would require at least a battle power of over a thousand, but if detected with a scouter, Yuujin's current power level was still only a few hundred.
To launch such potent energy blasts with only a few hundred power level was simply unbelievable—it showed that Yuujin's understanding and mastery of energy had reached a high level.
"Yuujin, go, go!"
On the temple above, Goku was jumping and cheering for Yuujin.
With two Yuujin below, she probably didn't even know which one she was rooting for. But it didn't matter—both were Yuujin, so she cheered for them together.
After a round of energy blasts without a decisive outcome, Yin Yuujin and Yang Yuujin soared into the sky. They brought their hands together at their waists and prepared:
"Kame…hame…HA!!!"
As their palms thrust forward, two massive waves of energy surged through the sea of clouds and collided, resulting in—
BOOM!!!!!
A deafening explosion, blinding light, and violent energy burst in all directions. Both Yin Yuujin and Yang Yuujin were swept up and flung away.
It took a while for the chaos to finally settle.
Astonishingly, where there was once an endless sea of clouds, a massive void nearly a kilometer wide had appeared!
"Huff… huff…"
Panting heavily, Yin Yuujin and Yang Yuujin exchanged a glance, and both couldn't help but smile wryly.
Yet another draw.
This was to be expected; one's greatest enemy is often oneself. How difficult it is to surpass oneself!
In nearly a hundred battles between Yin Yuujin and Yang Yuujin, the instances where one managed to break through the limits and defeat the other were rare—only a handful of times so far.
Approaching each other, Yin Yuujin and Yang Yuujin merged back into one, with the "Yin" and "Yang" characters on the forehead disappearing, becoming a complete Yuujin once again.
Countless insights flooded his mind, and a gleam flashed in Yuujin's eyes.
Although this battle had not allowed him to break through his limits, it still yielded significant benefits.
"Yuujin!"
Goku's voice rang out as she jumped down from the temple.
Yuujin's face darkened slightly—this reckless girl dared to jump down despite not yet mastering the [Sky Dancing], unafraid of falling to her death.
He quickly moved to catch the falling Goku.
"Until you've mastered the [Sky Dancing], don't just randomly jump down like that."
Tapping Goku's little head, Yuujin chided her lightly.
"Yuujin will catch me anyway, hehe…"
Rubbing her head against Yuujin, Goku replied nonchalantly.
Shaking his head in resignation, Yuujin slowly rose with Goku in his arms and landed back on the temple.
"Master Karin, thank you for your guidance all the time. Unfortunately, I feel like I have reached a bottleneck."
After setting Goku down, Yuujin addressed Karin.
"Indeed, that is true. Hmmm, there isn't much more I can teach you here as well, so it's about time you should leave and discover the bigger world out there."
"However, before you go, I have a gift for you."
Stroking his Cat-beard, Karin nodded and then raised his staff…
To be continued…
P.S
I changed the Yin-Yang Immortal Fist to the Yin-Yang Fist. The name originally designated by the author has too many Xianxia novel vibes, so I deemed it necessary to change it.
Also, guys, it is a new book, so I request you all donate all your powerstones to this fiction for the starting weeks so it will reach the maximum audience. I will be very grateful.
