Multi-Gene

Slightly surprised, the hesitation in David's eyes lessened as he brought the bail of serum to his face. It was a greenish liquid that swirled around the bottle in just the slightest movements if David's hand.

Instructor Aella might be quite cruel in her means but she hadn't harmed the students in anyway... At least, by her own hands.

Thinking about this, David didn't hesitate any longer and opened the lid of the vial. A familiar smell erupted from the depth of the bottle and hit his nose. David blinked his eyes and then eh remembered where exactly he had seen this exact same serum.

It always the same high grade Insta-Heal serum his master had given to him during the event a few months ago. The supposedly rare and very expensive serum was once again sitting on his hands.

While the instructor was at his bedside waiting for him to drink it and heal up. David's eyes twitched slightly. He couldn't bare to waste the serum.

Even if he was really seriously injured, he'd rather wait for his self-regeneration to kick in and heal him rather than waste the Insta-Heal serum. It was something you couldn't even lay your hands on even if you had enough money to buy it. 

The serum was a rare and life-saving treasure one must possess. It was even equal to a second life. Previously, David had been forced to take it and it had saved his life once. 

If he could just somehow not drink it and keep it instead, it was equal to having a second life. But then again, his self-regeneration was already at a crazy level, it was almost equal to the effectiveness of the serum but the serum could regenerate severed limbs whereas his self regeneration wasn't that powerful yet. He looked up and saw the impatient face if the instructor staring straight at him. 

"You don't want it?" Her voice chilled and her eyes turned cold as she asked with squinted eyes. 

David smiled but it was more of a bitter smile as he immediately answered. "It's not that instructor, it's just that it's too expensive for me to take it. Can I just drink it up another time?"

He looked hopefully at the instructor but it was a cold gaze that met his hopeful one. Chuckling bitterly, he had no choice but to do as she said. 

'What a waste.' David muttered in his mind and then under the intense gaze of the instructor, he gulped down the entire bottle of serum. 

Hot streams of energy flowed through his throat and spread through his arms, stomach, muscles and then his entire body. But the warm stream of energy flowed through his body aimlessly as though it couldn't find what it was looking for. 

David had been speaking to the instructor which was why he wasn't able to focus on slowing his healing rate, allowing his self-regeneration to kick in, his cells rapidly grew and fixed all the injuries in his body. 

The stream of energy endless flowed around his body, looking for some tissues and cells to fix. Suddenly, suction force erupted from within David's veins, sucking the stream of energy directly into his heart.

David suddenly felt his heart rate increase slowly, bit by bit but then, as he reached his previous limit which he had been stuck at in a while. But his Increasingly beating heart rate didn't slow down, instead, the speed suddenly increased explosively.

200CPM! 

300CPM!!

400CPM!!!

RUMBLE!!! 

His blood rotated around his body with an intense speed his body trembled and his muscles rumbled like thunder. The void trembled and rippled like waves in water and gravity became unstable, under the intense revolution of his blood around his veins. 

450CPM!!!

Every item in the lab not more than 10kg began to levitate, cycling through the room as though a small tornado had suddenly being formed as the gravity in the ward was being disrupted. 

David's body began to float slightly in midair. His closed eyes trembled as though he was going through some sort of pain. , sitting cross-legged, floating slightly in midair. 

470CPM!!!

Heat erupted out from his body, spreading through the atmosphere like a storm. His iron tempered veins creaked upon such power and was beginning to reach its limit. The void trembled insistently as though it was being turn apart by some power and the void was trying it's best to contain it. 

500CPM!!!

Suddenly, everything seem to freeze and it was as though someone pushed the pause button at the whole world. Half a second passed, everything was still frozen. 

A full second passed... Boom! Boom!! Boom!!! 

"Roar!!!" An explosive roar exploded from deep within David's mouth, his stomach rumbling, inflating and deflating like balloons. 

Everything in the room exploded into smithereens! Sending metal shards catapulting in all directions, embedded deep within the walls, ceilings and tiles. Creating massive holes within the walls and everywhere they touched. 

His body trembled and David felt his muscles shivered. He sucked in an ocean full of breath from his nose and then, slowly released them back to the atmosphere. 

He was beginning to calm down. Hs levitating body slowly fell back to the bed which was the only thing remaining in the ward. 

The energy within his body had faded and his blood revolution began to decrease until finally, it was beating the same as normal humans heart rate. 

The massive increase in CPM was just too great it shocked David himself. Seems the High grade Insta-heal serum wasn't anything simple. Even his own body wasn't simple. 

A smile graced his mouth as he opened his eyes and was greeted with a very beautiful eye staring at him as though wanting to bore holes through him. 

They were so close to the extent that David could feel the heat being generated from her face. He could see the tiny tiny pores on her skin and even the little bit of green at the outer region of her pupil. He couldn't help but admit, the instructor's was an absolutely stunning beauty. And if she wasn't very Ice cold, she would have seen lots of suitors wishing to have her.
