One Piece: Don't Worry, I'm a Doctor - Chapter 143: Care for a drink?

Empires rise and fall on the Yulan Continent. Saints, immortal beings of unimaginable power, battle using spells and swords, leaving swathes of destruction in their wake. Magical beasts rule the mountains, where the brave – or the foolish – go to test their strength. Even the mighty can fall, feasted on by those stronger. The strong live like royalty; the weak strive to survive another day.

Genius, antisocial, solitary, intractable , maniacal.

At the turn of every era, it is he who raises the flag of the rebel cross.

Winners take it all, losers take the fall.

He who brings order to a chaotic world, assembles talents and masterminds.

He who hides among the crowd, yet stands on the top of the world.

— The one and only, him.

In a hilarious and sweet xianxia romance set in Ancient China, Lu Zhao Yao went through life living ostentatiously in every way possible. She lived her entire demon life in a loud and brazen manner, reigning over legions of demons, and yet——just before she was about to retrieve the sword of the ancient demon king and rightfully claim her spot on the throne——she died.

In the most quiet and unobtrusive manner possible. How? By accident.

Mo Qing, one of her lowest ranking lackeys at that point in time, had killed her after he retrieved the demon sword and unintentionally unleashed the sword’s demonic aura onto the heavily injured Lu Zhao Yao.

Her quiet and untimely death, coupled with her firm belief that Mo Qing had sneakily betrayed her by lying in the shadows and waiting to strike the final blow and reap all the rewards, nurtured a heavy grievance within her. Lu Zhao Yao refused to head to the underworld and reincarnate, hanging around in the human world in her spirit form.

Lady Luck, however, had not completely abandoned her.

One fine day, a female disciple of the Immortal Sect (Zhi Yan) fought with her childhood friend and banged her head onto Lu Zhao Yao’s grave. To Lu Zhao Yao’s utmost delight, she was able to possess Zhi Yan’s body for short periods of time after this.

Thus began her journey to avenge her very own death by destroying Mo Qing——and, in the process, resume her rightful place as the King over all demon sects!
