Multi-Gene

Suddenly, Jason clasped both of his arms and he yelled. "Condensed lightning Spike!"

The strands of electricity around his body and the four arms were like strands of uncontrollable whips. They simultaneously converged onto his two palms, forming an intense lightning spike.

He then shouted out. "Strike!"

"Crackle!"

The air snapped madly, sizzling intently with an insane intensity. Without hesitation, he flung the spike towards David.

It was as though the spike was being catapulted as it moved towards David with astonishing speed.

David\'s expression changed instantly and he let out a curse. "Fvck!" said was thoroughly shocked. A long range energy attack? Even Phyllida didn\'t have that.

At this moment, he couldn\'t help but sigh at the geniuses in this world. Although the energy wasn\'t generated from his body but from the gadget behind him, it was still praise worthy to reach this level of practice.

In that moment, David immediately leapt backwards. But he was still a bit slow. 

The spike came to fast and to sudden as he had been stunned by the feat. David was hit squarely in the chest in mid air. 

With a thunderous boom, the thunderous spikes vaporized into a massive  amount of electricity and it scattered around David\'s body, shrouding him into some kind of misty electricity, before wickedly smashing him into the wall behind him. 

The force ruptured the wall into countless fragments as stones and sand filled the entire area. 

"I must say, you are honestly really strong. But it\'s a pity you met me." Jason calmly. Walked through the myriads of dust and sand in the air. 

"Now, I won\'t hold you for the fact that you tricked me. If you willingly relinquish the stuffs you took from the old man, i promise not to break any of your limbs otherwise, don\'t blame me for being mercil..."

"There won\'t be a need for that." A voice was heard coming out form the cloud of dust, suddenly interrupting Jason\'s speech. 

Jason\'s face changed drastically and he immediately stomped his foot forcefully, retreating backwards with all his strength. 

But he had miscalculated, a streak of dark light flashed amidst the disturbing dust, flashing across his eyes in a arc. 

"Double Phantom Slash!"  David suddenly appeared behind Jason in a flash. 

His two finger were shaped like two incredibly sharp sword as the streak of  after images they had created stopped right on the fingers. On the tip of his finger, drops of blood dripped down. But it wasn\'t his blood. 

David stood up from his forward bent position and he turned around. In the middle of his left finger, four charge cells dangled limply on them with a few snapped wires connected to them. 

Behind him, Jason was stunned as he looked at both of his arms, they laid limply by his sides and he couldn\'t gain control of them again  as he wished. 

Suddenly, he heard a few snapping sound and the electric arms behind him crumbled like dominoes and scattered to a few pieces of scarp metals on the floor. 

"Ahhhh! My arms! You... " Suddenly, he bit his lips tightly and refused to say anymore. 

He stared intently at David with flames of fury in his eyes but it seems as though something was stopping him from saying anymore. David could guess that it was his system. 

"Fine, I will remember your good will. My name is Jason, what is yours?" his expression was solemn but his anger refused to die down. 

Claire had advice him to retreat otherwise he would suffer more harm if he continued to persistent. 

David was unruffled about giving out his name. If he was at his peak, beating two of Jason although troublesome, should be feasible.

"I\'m David. If you are done, you can take you leave. I\'m busy in here." David said off handily with his arms crossed leaning against a wall, looking cool.

Jason\'s body trembled as if he was trying hard to control his anger. "Good. That\'s good. David, I will remember you." After saying this, Jason turned around decisively and left the basement.

The basement was already a mess at this point. The brick walls had collapsed into countless stone fragments all over the floor.

The machines that filled the basement had turned into different scrap metals that were unrecognisable.

"Ppft!"

Blood suddenly spurted out from David\'s mouth like a jet stream. That wasn\'t all, in his chest, few blood vessels burst open, spraying out cloud mists of blood around his body. He immediately fell to his kneels as he gasped desperately for breath.

Reaching for his back pocket, David grabbed at a syringe the size of his index fingers. In less than a second, he stabbed himself at the hole that his combat Suit previously had. 

Using his ability, he hurriedly circulated the blood in his system despite the pain he was experiencing right now. 

His eyes involuntarily closed as David experienced every cells and organ within his body cheer in joy. As he recovered, David felt the Mysterious nourishing energy provide potent nourishment to his body an his organs. All the previous wounds he had began to heal at a rapid rate. And the blood vessels began to heal as the tears within them closed up entirely. 

His body nourished by that energy, nor had their rate of evolution slightly hastened. 

His slightly muscular nature got even more muscular and his already tough skin got even more tougher. And his bone seem to have condensed more and became more heavier. His organs seem to have gotten at least a year younger than they previously were as they were more energetic. 

David was stunned and confused. The normal beginner Insta-heal function wasn\'t even close to this. Even the intermediate Insta-heal wasn\'t as potent as this. Which means this is either an advanced serum or even a perfect grade serum. Such serums weren\'t even available for sale even if one is rich enough to purchase it. 

David\'s expression turned serious in an instant. He didn\'t take this situation lightly at all. The old man had been so generous to have granted him a serum of such quality. That means the old man had taken him as a disciple for real. Suddenly, David stood up. 

He knew what to do now.. But firstly, he needed to checkout what was in the old man\'s back pack first.
