Vaudevillain - VV4, 25 - Makeshift Anti-Air

I had been abroad to do medical volunteer work, when I was swept up in a civil war. I was killed by a rebel soldier, while taking a bullet for a patient. But when I finally woke up, I had become a child?!?And in front of me stood a destroyed carriage and a group of oddly dressed people, who were unconscious!“It’s just like a Murim world.”As I hurry to perform first aid in an attempt to save even one person, I realize that this world is that of [The Supreme Demon King], a Wuxia novel I’ve enjoyed reading.After meeting the rescue team of the ‘Three Great Doctors’, I found out that one of the person I saved was the protagonist of this novel, the future Demon King ‘Yeo Haryun’!“Hey, since I’m indebted to you for saving me, call me ‘hyung’.”For saving his life, I become sworn brothers with the future Demon King, and the White Dragon Godly Doctor, one of the most knowledgeable people around, recognized my potential and took me in as his disciple. This is the story of how I became the greatest physician in Gangho!

After her rebirth, Qin Yiyi became the daughter of the Qin Family once again. It’s just that her parents didn’t love her.

It’s alright. I’ve always relied on myself.

What? She had no education, no ability, no brain, and was not as smart and clever as Second Miss Qin?

Qin Yiyi chuckled and turned to leave.

Over the past year, she had gotten sick of being a top student at the piano and accidentally became an ancient cultural endorser while also somehow receiving a doctorate and accepted a professor as her disciple…

A top-ranked medical professional said, “What, Master Qin isn’t here? Sorry, we’re leaving too.”

Ancient martial arts family had this to say, “Qin Yiyi is my little grandaunt. If you bully her, you’re going against the ancient martial world!”

9th master chuckled. As he looked around, his thin lips curled up slightly. “Everyone, do you think I’m dead?”

What if life could be repeated?

But he became the clan uncle who was once called a lunatic?

Alas, wearing open-crotch pants in front of me, crawling on the ground, is it my two-year-old self?

I originally wanted to give my former self more New Year’s money, but I never thought that I would go from a braised pork stall to a food giant, from a small factory to an industrial empire.
