Not splitted, as far as I remember, Ye Xi Wu's fragment left accidentally (again, cannot be 100% sure, translation was bad at that time)
t follows closely but not entirely. For example, when Su Su goes back in time she makes a deal with YeXiWu - she will give her the body and susu needs to save the Ye family from TTJ. Su su also is shown YXW's life. Moreover in the novel it is told from early on, that YXW won't survive past the age of 20 by the symmetrical/asymmetrical appearence of her face.
In the novel, when TTJ searches for and find's YXW's soul, and then plans on putting YXW's soul into SuSu's body. What happens to YXW's soul once TTJ finds out it was not YXW but SuSu he fell in love with? Does YXW merge with SuSu?
Also if TTJ died originally at the Ice lake, then why would Devil-god tell TTJ later in new timeline that time has not come for TTJ to die and for the two of them to merge? I mean at that point, all the pain and suffering from the original timeline had been experienced already.
I understand timeline has changed, but still devil-god had to be aware somewhat? Or is he unaware of the changes because he is still limited in power and not devil-god yet?
