System 001 encounters a spirit born from the essence of heaven and earth, then takes her to experience life as an insignificant side character in countless worlds...
World One: The Side Character Cousin
I'll think of more worlds to write later.
P.S. Since the heroine is a naturally born spirit, she's extremely beautiful and has a total heartthrob physique~
This is just a fun, freewheeling story. Everything comes from the author's imagination and hasn't been researched, so just enjoy it for what it is~
