I Really Need to Control Myself—Hard

Like everyone else, Dong Xi can control his own body. But for him, that "control" operates on a near-conceptual level—from hormones and glands to hair and bones, down to every fiber of muscle and every single cell, he wields total authority over his own flesh. As long as he understands the mechanics, he can enhance his athletic performance, compress excess tissue into dehydrated tools extruded from his body, reshape his facial features beyond recognition, or project neural filaments to manipulate others' bodies. Yet this same power also allows him to prematurely detonate the "time bombs" hidden within human genes. Armed with nothing but a mortal frame that answers his every command, how does he resolve the crisis of humanity collectively "self-destructing" one day in the future? And how does he outmaneuver the shadowy forces that planted those bombs in the first place? "Mr. Dong Xi, how did you manage to save all of humanity?" "It's simple. Because I can control my own arm, I can fling the atomic nuclei from it and spark a nuclear explosion with my bare hands." "...And after you discovered your uniqueness, what did you do first?" "Good question. Back when I was still getting used to controlling my body, I ran into a robbery..." "Wow—you must have enhanced your strength and durability and beaten them to a pulp, right?" "No. I controlled my own blood to spray out of my mouth, faked a hit-and-run, and swindled a huge sum of money from them. That was my first pot of gold for saving the world!" "???"
