[The Nine Gates] Transmigrate?! Who's Transmigrating?

Where Did You Come From, and Where Are You Going?

(A fanfiction based on the TV drama The Mystic Nine. 12478 transmigrates in reverse. The entire story is set in an alternate universe. I wrote it purely for fun, and the pairings include 18+24. The plot doesn't have much logic, so please forgive any out-of-character moments. I really like settings involving "supernatural abilities," so I enjoy giving characters all kinds of outrageous powers. Just have fun reading, and please don't overthink it. Thanks!
