The Mad Scholar's Invincible Sword

There is a mad scholar who spends his days carrying a battered wooden sword on his back, telling everyone he meets that he is invincible under heaven.

His name is Chen Xun. He wanders the world, regaining his sanity after every three years of madness. Over and over, the cycle repeats without end. No one knows where he comes from, and no one knows where he is going.

What he bears upon his back...

Is it an ancient curse?

Or a path of cultivation through self-imposed imprisonment?

Or perhaps the shackles of a fated calamity from which he can never break free?

Along his journey through the ages, some scoff at his wooden sword. Little do they know: when that sword is drawn, every star in the sky dims, and the gods and demons of all heavens bow their heads!
