Successfully Creating A Genetic Serum

David smile widened as he was successfully moving his arms perfectly in that gene world but he didn't dare to stop his oscillating arms so as to not mistakenly destroy something.

But with the perfect control he had over his entire body, it was very easy for David to maintain oscillating his arm at that exact same frequency, making it easy for him to move without making a single mistake. 

Out of the hundreds of genetic holes he had in his brain David couldn't decide which hole he should choose from. They were just too much.

Ultimately, David chose one at a random and then got to work. He oscillated his arm, making the little prosthetic arm in the gene world to also move according to his control. He then proceeded to carefully remove the unnecessary DNA strands.
