"You see, this treatment is kinda like the old chemotherapy, but also part injecting viruses that seek to attach to certain cells, but instead of making more viruses their coding will cause the cells to shut down and die. But this all requires energy activation, but it's really sensitive, and Draco already has such an unstable energy core for a heart, if I mess with it I could accidentally stop the output long enough for her to die, and since I don't know how to measure the heart's energy, I can't convert it properly." Kim explained. Honestly, he had simulated the same treatment on normal people, and almost more than 94% of the time the treatment worked. That being said, Draco was different, and if he treated her normally her chances of surviving were more like 2%. And numbers do not joke, the teen had to double take at the extremely low chance of the older teen surviving.
