Ethan Blackwood was an ordinary young businessman. At least he was until, during a trip, he found himself involved in an event that defied all logic he knew. Unwillingly and unexpectedly, he becomes entangled with supernatural beings, and to make matters worse, he has to deal with a demon inside his body! Now, he must become stronger if he wants to survive the challenges ahead. Will Ethan, with his new abilities, be able to survive the new challenges involving gods and demons?
Ethan stood before the Ratkin, looking at them resolutely. He knew very well that they were incredibly agile and had physical endurance even superior to humans. Still, Ethan decided to impose physical exercises on them, not to increase their abilities but to teach them military-like discipline.
"Listen carefully," Ethan began. "These exercises are not just to strengthen your bodies but to strengthen your minds and spirits. You need to learn to work together; that's what will make you strong as a unit."
Ethan relied on an internet video tutorial, repeating what he had seen. He showed them a series of basic exercises: push-ups, sit-ups, short sprints, long runs, and various stretches. Although it might sound basic or silly, he had never been in the army and didn't really know how to do it. For them, who came from a medieval society, this was quite revolutionary. The Ratkin generally watched with curiosity, although some showed signs of disdain.
