You remember the chapter that the god took over mimi’s body right? I think what happened is that in the timeline before, the god completely took over his body, so all the actions that we saw in this most recent chapter, was what he (the god) did as mimi. So kinda yes, the past mimi in that timeline and the god were the same person. However, now in the current time, the god failed in taking over mimi’s body, so they are not the same person anymore. That’s what I’m assuming is happening. I’m sorry if what I said was confusing lol.
in simple terms, god took over/used mimi’s body in old timeline and he was the statue that Li met, current timeline mimi is just his normal self that we know.
So they are the same person?... enlighten me people
