Nuclear Facility, Absorbing Gamma Ray

David raised his right hand to his face and as though they were a bunch of nanobots, his hands transformed into a webbed hand and then changed again as his fingers started to transform into pure blades one by one. As though it wasn't enough, a pinkish slit appeared at the center of his palm, opening up to reveal a pitch-black eye appeared. 

This time, there was sweat dripping on David's face. It can't easy to construct this eye. The eye rolled about, looking around curiously before his hand transformed back into its usual form. With this ability, he could regenerate dead cells, recreate an entire DNA structure in his body. Naturally, he wasn't afraid of radiation destroying his DNA! He was the perfect fit for the Technique! 

"Ahhhhh!!!"

David calmly came out of the train, ignoring the commotion he had caused by transforming his hands back on the train.
