During my time volunteering as a medical professional overseas, I found myself in the midst of a civil war. While attempting to protect a patient, I tragically lost my life to a rebel soldier. However, upon awakening, I found myself in an unfamiliar world. I was now a child next to a destroyed carriage and a group of unconscious strangers dressed in strange attire. After quickly reviving them, I realized that I had entered the world of "The Supreme Demon King," a novel I had previously read. Working alongside the "Three Great Doctors" rescue squad, I had the opportunity to save the life of the future Demon King, Yeoharyun.
As a token of appreciation, Yeoharyun became my blood brother, and I was taken in as a disciple by the knowledgeable Baekrineuison. With their guidance and my medical expertise, I worked tirelessly to become the best Gangho physician possible.
