Star Iron, my clone is taking over Onpharos

Having transmigrated to Onpharos in the Star Iron World, Bai Yuan discovers that he actually has an avatar that can devour and grow.
And so on this day, a terrifying being appeared, devouring all sorts of monsters in Onpharos.
Titan Fire Seeds and Annihilation Lords became sustenance for the growth of the clones.
An atmosphere of terror permeated the entire Onfaros.
Of course, none of this has anything to do with Bai Yuan, the perfect citizen of Ohema and Miss Xia Die's roommate.
"The one who did the bad things was my clone; I am definitely a good person!"
P.S.: The story is definitely not limited to Onphalos; there will definitely be other world storylines later on.
PS2: Xia Die is definitely the main heroine, but she's also definitely part of a harem.
