Since ancient times magiculus particles exits in the world of magic. It was way much later when they discovered it and stated using it. Every human develops a magiculus vessel with time which stores magiculus particles in the body.
At the center of this vessel exists a core which control the flow of magiculus particles in the vessel. It's pretty much impossible to see the core with normal means. But Xin had a way for it. In his past life, when he was working in the Research division he had devised a way to split open this core. Add programming into it and make it do different things inside the body.
Out of these many things, one was programing the core to release the black hole inside the core and make a living creature suck from the inside.
It may sound complicated but Xin had researched and mastered this method for this use. While reminiscing about the past Xin was dragged to reality after hearing Jia's derivation.
