"Second star."

His muscles trembled and his mass turned increasingly dense. In that exact moment, Vather was right before him, with his fist slamming against his chest. 

David's muscles rumbled, it was like the sleeping roar of a dragon as he Thrust his fist forwards.

Fist against fist! 

Boom!!! 

A massive thunderous explosion resounded from the two attack. Suddenly Vather smirked, there was a sound of mechanism being operated and his a supportive system that could only be seen in a large truck emerged from beneath his feet, latching heavily to the ground to give him support. 

The sound of machine being activated resounded and an explosive force was forcefully yanked off the ground, being transmitted from within Vather's body as he punched out. His fist rapidly expanded to twice its usual size. 

Boom! 

Their fist collided and David felt as though he had been hit by an entire mountain, he staggered backwards with a startled look on his face. 

Vather pressed forward. He took another step forwards, and the exact same mechanism activated beneath his feet. He punched put again. 

BANG! 

David staggered three paces backwards, this time his expression grave. This blonde guy was proving truly difficult to deal with. 

His suddenly spread his hands and his hands morphed, forming a sharp claw, his legs bending backwards in the process as furs erupted from within his body. David suddenly dropped to the ground on all fours and he vanished. 

Bang! Bang! Bang!

Sparks flew from Vather's body like fireflies, David was like a flickering ghost, slashing his claws around Vather's skin with extreme speed. Multitude slash marks appeared in vather's skin, the injury appearing to be grave as chunks of flesh was being ripped out from his body.

"Haha!" Vather laughed maniacally. It was as though he couldn't feel any pain as blood and chunks of flesh was being ripped out from his body.

"Haha! You are finally taking this seriously." Vather laughed maniacally, bit minding the fact that his flesh was literally been ripped apart by David.

David's brows furrowed slightly. He then moved backwards retreating a few distances away from Vather.

Vather laughter of madness suddenly stopped and his expression turned savage. "This is the difference between us."

The chunks of flesh and blood on the floor suddenly gathered together as though they had sentient, then rolled back unit his body. As though that wasn't nearly enough, Vather's body suddenly began to morph into a strange shape. His bones crackled as though it was breaking apart and his legs snapped backwards, his nails growing longer in the process and golden furs appeared all over his skin, growing from every part of his body.

He suddenly went down on all four, similar to David as he looked straight into David's similarly golden pupils, a smirk on his face.

David's eyes widened and his expression turned incredibly grave. Had Vather just replicated his technique. If it was so, things would become very difficult at this moment.

"Looking at your shocked expression gives me joy, it's really sad I would still have to kill you." he suddenly moved. He was like an experienced beast preying on its prey, like a phantom shadow, he moved silently, circling around David looking for an angle to his defense.

Suddenly, he pounced at him.

David pupils constricted and he whispered. "I've actually never used this ability before, you shall be the first test subject... "

"Moon Howl!"

Hoooooooooooowl!!!

A massive reverberation clawed it's way out from David's throat as he howled uncontrollabley to the skies. A powerful resonance shot upwards the skies, a dynamic rumbling thumped in mid air and suddenly, the clouds darkened as though it was night time.

A mighty pulsation erupted and a full moon that was the size of a fist appeared in the clouds, glowing powerfully towards David, bathing him with a silvery glow.

David felt the ray of silver light touched his skin and he felt as though he had been placed in his mother's embrace. The feeling of warmth bathed him and it was as though he had been placed within the energy tank, but this feeling was a thousand times better. David moaned softly as he felt his strength increase by three times its previous strength.

But what made David pleasantly surprised was the fact that this increase in strength seem to be partially permanent, he didn't know how to explain.

This took time to explain, but in reality, it happened in an instant.

David's pupils focused back and he seem to see every thing in sloe motion. He saw Vather rushing towards him with breakneck speed, but to David, he couldn't be any slower.

David tilted backwards, and he immediately rushed forwards explosively, the ground exploding beneath his feet in a web shape manner. 

He suddenly faded, in mid movement, he shifted sideways, avoiding Vather's claw attack on his chest. 

David sharp nails suddenly glinted, as he stabbed his right claw deeply into Vather's chest and swiped downwards at the place he sensed the energy source. 

He felt some sort of resistance, from Vather's bones, but they weren't able to stop his strength as he was about to claw into Vather's chest, Vather suddenly moved his chest slightly, making David's claw miss the intended target.

Boom!!! 

Vather was slammed backward as though he had been hit by a mountain sized hammer, leaving only a large chunk of flesh and a rib bone on David's claw.

David's eyes sharpened. Vather's energy was near limitless, if he truly wanted to kill him, he would have to yank the energy source out otherwise it would be very difficult to kill Vather. 

Moreover, David was somewhat living on borrowed time. The lighting seed within his body would erupt in five minutes, he needed to end the battle pretty quickly. 

There was the probability Vather was immune the electricity, since he was made up of nanobots, David didn't want to bet on that fact even if the probability was low. 

Following his first attack, David moved on all fours like a true beast, the wind slapping against his skin as he moved, he had caught up to Vather's moving body so quickly. 

Bang! The air undulated. 

He swiped his claws at Vather's chest once more, right at the energy source, but Vather was giving David that chance. He quickly changed back to his human form, thrusters on his hands, as he pointed his palm sideways, his body going the opposite direction. 

"Where do you think you're going?" David leapt to the sky, as though there was an invincible platform below him, he grabbed at Vather's feet, yanking him back, slamming him towards the ground. 

With his new strength, Vather was now like a new born pup to David, his body was like an hammer as David slammed it repeatedly in all directions towards the ground. 

Boom! Boom! Boom! 

Whoosh! 

Vather's legs turned slimy and he managed to escape from David's hold, flipping and flying towards the distance. 

He immediately roared furiously at David a few kilometers away from him. "You have angered me. I will make sure to enjoy torturing you before I_ " He wasn't able to finish his sentence when his eyes opened wide in shock. 

At the corner of his eyes, a second and a third David had suddenly appeared before him as though they had teleported, their claws on his chest as they tore through his chest and clawed away the energy source within his chest. 

Two Davids, the one at the distance and one of the two faded away like smoke, leaving only now of then left. 

Yank!

A bright light encased in some sort of wiring and chips was suddenly within David's claws

"W-what is happening." Vather was confused. As he saw the David gazing at him with indifference. 

It wasn't an illusion! It was real. 

"I-i hadn't even u-used my true strength yet." Vather muttered slightly, strength leaving his body as he staggered backwards, falling at the ground with his aura flickering and declining. 

"I know, but I can't delay any longer." David responded as he kept the massive energy source within his storage ring. 

He stared coldly at Vather who was staring up at him with unwillingness and hatred. He gritted his teeth with madness in his eyes. David shook his head softly. He had seen this gaze a lot and was already used to it. It was the gaze those at the verge of death usually gave him before they died. And most of them were stronger than he was, but he was still able to kill them. 

Although David had no idea how strong Vather truly was since he own near limitless amount of energy and the versatility of his nanobots were being ordinary, still David had killed him at the end, unexpectedly. 

The threat he felt from Vather with his intuition was massive and David was well aware Vather hadn't been truly serious with the fight, who knew what would have happened, but because he had taken David lightly, he had met his end at last. 

"Hmph!" David suddenly groaned and he went numbed as his body slammed backwards.
