Time passed it's been over a month since Nira and Zefflar came to this planet, both of their Battle Powers were steadily growing. Nira had the most improvement with the implementation of a basic ki refining method {Swallowing Gale} she now also cultivated the path of ki refining.
Swallowing Gale was a basic ki refining method its purpose was to store up the ki that is digested with food and boost endurance. When the average life form eats it's impossible for them it digests 100% of the energy stored in the food. Swallowing Gale allows a person to forcefully devour the remaining energy that would have dispersed otherwise, store it in the blood, muscles, bones, internal organs, and cells.
Although basic it can serve as a life-saving trump card, Swallowing Gale isn't just restricted to normal edible food. Anything that can be digested and refined for energy can be eaten as long as Swallowing Gale is circulated, Trees, Bones, metal, etc. As long as the practitioner has a high enough cultivation of Swallowing Gale his rate of survivability, endurance, and bodily toughness will be raised.
As a Saiyan Nira's rate of absorption of energy is already insane, so she can eat as much as the Swallowing Gale Technique demands. In Zefflars past life such a technique remained just a theory, with the advanced technology he repeatedly ran various test to see if it was possible for him to practice such a technique, the results however always came back negative with an 80% chance he would starve to death. Such a technique would have been useful in his early stages of devouring Mars. In this life, however, the blessed physique of the Saiyans allowed him to do so much more without such limitations.
Even in this world, the situation was completely different for Earthlings.
On Earth, Master Roshi and other such Master Martial Artists had to persistently cultivate for 50 to 60 years to train ki. As they are born with very little ki, training in martial arts is very slow. However, as a plus side their understanding of the essence of martial arts, and ki is even more detailed.
The majority of martial arts and Ki has been thoroughly studied by them.
Saiyans and even the vast majority of the myriad of races in the Universes in the Cosmos are born with a fast growth rate and great power such that they neglect the essence of training and the benefits it brings and only uses Ki as a form of a killing tool.
So much so that their application and attacking methods are extremely crude and rough. Zefflar himself is the prime example of the brilliance of the human race, as weak as they may be humans have unlimited potential. In a Universe with laws restricting the use and practice of Ki, he single handily found a way to strengthen himself anyway.
This past month also let him confirm a theory in the past he couldn't confirm. Would it be possible to devour the Ki of targets he kills? He found it was possible but the Ki devoured is incredibly impure so he can only devour one to 10% depending on how strong the target is, only a small amount but something is still better than nothing. But he soon found out another problem he can rapidly grow using this method, but without the Yang part of his Martial Arts it would just mess up his foundation so it was impossible for him to use this method recklessly.
"In the end, the Earthlings use of Ki methods is a pressuring task I need to complete as soon as possible. I am basically powerless to accomplish this step without years of studying and practice, It seems I have to hurry and complete the task here and visit Earth soon."
In the following days, Zefflar would take Nira out every day to hunt, and train. Every day their battle power steadily increased by a small margin.
Even though this is the case Zefflar still strictly put emphasis on their training of Ki. So no matter how much Nira resisted, he still strictly required that both of them tie heavy boulders on their backs for half a day and train their bodies. Running 10-15 miles, 1000 push-ups, 1000 squats, and running on scattered rocks in the river to train agility.
At night he would meditate for the entire night, while Nira would eat using the {Swallowing Gale} technique and practice Ki sensing before going to bed.
The constant growth of his strength every day once again made him feel that addictive feeling of rapidly getting stronger. Causing no small amount of joy in his heart.
~~~
Two months later, in a broad plain.
Zefflar and Nira can be seen moving at high speeds, constant booming sounds could be heard, as they fought hand-to-hand repeatedly. The two were standing mid-air staring at each other with serious expressions.
"Ha!" Nira adopted a fighting stance and attacked, while energy inside her body surged like a raging wave.
Hooh ~
Surging energy appeared between her palms, while the surrounding air seemed to compress and quiver.
Suddenly, a shiny blue light appeared in her little dainty hand, followed by an even brighter light dazzling to the eyes.
"Death blast!"
Nira aggressively thrust her hands forward, and a scorching energy swirly exploded forward. The dazzling blue light swirled forward like a monstrous wave, pressuring the surrounding air. An irresistible force charged the skies, creating a vacuum, in the air.
Rumble!
The beam circled in the air like a Dragon, and the air trembled restlessly. The powerful wave charged into the distance overbearingly.
In response, Zefflar just calmly condensed Ki into his hand like a small blade and chopped lightly at the incoming attack.
Boom Boom ~
The wild energy swept the surrounding area as it dispersed upon impact of Zefflars chop.
Zefflar stood in mid-air of the surrounding mass destruction with one hand behind his back, the other effortlessly chopping Nira's attack in half.
When it disappeared, and everything calmed down; an utterly ruined and destroy forest of at least 500 hundred yards. Numerous large pits can be spotted here and there, on the plain which looked like they had been blown by an air strike.
All that remained was an utterly arrogant voice,
"You lose!"
