I had been abroad for medical volunteer work when I was caught in the midst of a civil war. While shielding a patient, I was struck down by a rebel soldier’s bullet. But when I opened my eyes again… I was a child?!

Before me lay the wreckage of a carriage, surrounded by unconscious people dressed in unfamiliar attire.

“This… it feels just like a Murim world.”

Rushing to provide first aid, desperate to save even one life, I soon realized—this world was the setting of The Supreme Demon King, a Murim novel I had loved reading.

After encountering the renowned ‘Three Great Doctors’ rescue team, I discovered that one of the people I saved was none other than Yeoharyun—the future Demon King and protagonist of the novel!

“Hey, since you saved my life, just call me ‘hyung.’”

For my life-saving efforts, I became sworn brothers with the future Demon King. Soon after, Baekrineuison, one of the most knowledgeable physicians in Gangho, recognized my potential and took me in as his disciple.

Thus began my journey to becoming the greatest physician in the Murim world!
