Multi-Gene

David poured the necessary materials into his storage ring and gave to Hazel. "Now that you have a body, can you use one this?"

"I'm AI, not human. Of course I can't."

David rolled his eyes, emptying the contents to the ground, he said. "You know I assume your attitude would be a lot different by the time your body fully develops, I guess you will still remain the rude bitch you are."

Selecting the materials, Hazel giggled softly as she turned around to face David. "Why? You don't like it?"

Showing the whiteness of his eyes, David scoffed, turning to leave towards the entrance. "Who likes being constantly spoken to rudely?"

But then his voice turned quiet as he whispered, gazing at Hazel's working figure. "But its great to have someone to trust. And turn hopelessness into anger."

Completely ignoring David, Hazel's hands worked fast as she started to build the transmutation device together with the old man's help.

With his blood still within the old man's brain, David could sense if the old man even whisper a word of lie which was why he wasn't bothered to inspect them.

He sat cross-legged at the entrance of the tunnel and a a bloody Orb floated in the air above his palm. It was the blood Orb he had gotten from the Silverback Ape.

In one gulp, he swallowed it down and closed his eyes, spreading his senses towards his body for any signs of abnormality.

Time passed but David didn't feel a single bit of feeling except the increase in his heart rate from the energy. David's mood was dark and he was about to give up when he suddenly noticed a tiny muscle located at the wrist was vibrating softly in a rhythm absolutely different from the any technique he was familiar with.

David's eyes lit up and he immediately controlled the rest of his muscles to move in the same frequency.

His body released humming sounds that elevated sometime and reduce at the same time. The rock below him would simetimes explodr due to the destructive frequency created most times.

In just a few seconds, vast amounts of steam puffed out from David's head as though he was a kettle and his robes burst into flames only to be dounced by ice rapidly coating his body.

All of a sudden, David trembled incessantly as though he was having a seizure and then his body started to expand rapidly as though he was been inflated by air.

At first his arm grew to twice their size and then reduced and then gre again. After which his left leg experienced the same tribulations as it expanded, turning into a pillar like leg.

In the blink of an eye, David's body inflated by an entire fold as he sat on the hollowed out ground, a wry grin on his face as be clenched his fist, causing a sonic blast just from his finger snapping.

Finally, he was able to extract the technique from the Silverback Ape. A technique that doubles his strength and could work on his strengthened body, how could David not be happy about this?

His body reverted back to their original state and he reduced from his almost 4 meters tall height to his usual alsmot 2 meters height.

In a good mood, he turned back and saw Hazel was still in the middle of seeing up the device and he asks. "How much time till you are done?."

"30 minutes at most, don't rush me."

"Alright. I'm only asking." David backed off, not willing to allow Hazel ruin his good mood.

"HOO!"

In that moment, a brilliant flash of silver-white saber gleam lit up the gloomy night. The gleam shot like wind, shone like moonlight, and flew like a huge meteorite falling from the unknown skies.

In that split second, the Thin-sized gleam of sharp blade whipped up a violent whirlwind through the wall and towards David.

"BAM!!!"

A hand shot out unexpectedly from within the mountain, catching the thin illusory blade firmly in its grasp and halting it dead in its tracks.

David's eyes widened in shock and anger! Instantly, a blood red line shot up from his abdomen all the way to his forehead. In the short span of a single breath, his body swelled up all over as large bands of muscles bulged out like tumors. His entire person ballooned into a glistening titan more than four meters tall meters tall.

"Ka-cha!"

David squeezed his hands, anf the blade in his palm exploded into pure energy.

Massive wind pressure and energy waves blew around cave, causing stones, bricks and dust inside to fly about wildly.

"I will take this outside. You should hurry up, we have company."

"Hell Massacre!!!"

"KABOOM!!!"

David flew upwards through the mountain and summoned MEGATON, slashing upwards at the with all his might, resulting in a resounding boom.

The second illusory blade broke with a "KA-CHA," while it shattered into a million pieces. The mounting , weighing more than a hundred catties, shook intensely like an earth quake.

A copious amount of boiling energy waves flooded the entire sky. An handsome middle-aged man floated in mid-air, gazing downwards at the mountain with a smile on his lips.

"YOU COURT DEATH!!"

A ferocious roar rang out suddenly.

"BOOM!!!"

In a split second, the mountain peak was shattered to smithereens in a massive explosion. A flash of diamond-red charged savagely into the air—it was none other than David.

He bulldozed through the mountain with Megaton in hand as piping hot energy waves rolled off his entire body.

Immediately he popped out, there was no warning as he struck heavily.

"HOO!!"

The blade flashed brilliantly at the Demigod, but swung through thin air, causing the air to howl and sparks to show from the friction.

David's eyes shone like daggers and he glared around. A web of pale red and black veins, like tattoos, ran over his bare upper body, twisted and knotted in a sinister manner.
