While I was writing the full draft, I didn't know I wasn't allowed to write across channels, so I'm posting the modern-day extra here as a bonus. It's free~
Basically, Su Chiyan tinkers around and creates an elixir of immortality. Thousands of years later, in the modern era, Bai Yi and Gu Chengyuan transmigrate over because of an incense burner.
This modern-day extra is a complete case and has some connection to Yin Gu Xu. It takes place later on.
I came up with the idea for Yin Gu Xu while writing this extra.
Just have fun with it. No need to scrutinize the timeline too closely!
Theme: A fulfilled life.
Oh my god, I can't even finish watching this!
I asked why there are so many extras missing. It turns out they can't be released.
