Remix of the same song for an anime opening and ending

[DarkAngel]

i came across mo dao zu shi's ending and at the 9th episode of the first season the same song sounded way better.
did you encounter this in anime before?

 

[MoonlightShadow]

It's all the same

 

[Star_Of_Hope]

I don't think I paid that much attention for an anime opening or ending.

 

[Rinko]

I haven't seen or heard that one before.
Let me check.

 

[Kaname]

Do you have the link to both the versions man?
I am too lazy to find those episodes just to listen the ending.
