Do you know what happens if you mix nitric acid and glycerol ether? Nitroglycerine. Do you know how to get these substances? In what ratios should I combine and how is this done? I missed something. Let's keep it simple. Gunpowder? Charcoal, sulfur and saltpeter. Much easier. Can you do it? You probably know where the jugular vein is? At least how to get electricity without which you can’t imagine your life? I know. This is my job. Know everything. In the past, I was a person who some called a hero in the shadows. Others cursed me. Still others used it. I have so much blood on my hands that I could populate a city. An agent of death. Creator of orphans and widows. My name has been erased as if it never existed. And rightly so. Weapons should not have a name. Just designations. In Japan they used to scare children by calling me Tek-Tek. I never thought that someone like me would be given a second chance.
