Rookie on the Path of Life and Death

A pseudo-immortal body transformed into a jiangshi,

contagious corpse poison,

the standing of the Way of Life and Death,

a born talent for wiping out entire teams.

The little princess of the Corpse Path, Miss Zhao of Tai'an!

You could call this a fanfic based on the Transcending the Nine Heavens manhua, though the actual content isn't closely related. You could say it isn't a fanfic, but it was still built on that foundation.

In short, it's a dull little short story written by a setting-obsessed author to show off his worldbuilding.
