@greyhud90 @Scrabbleman It's like the huge number of chinese "fake" isekai. Nearly all chinese story with isekai, the isekai part is useless and rapidly forgotten. But it pushes people to start reading
Some examples: Master of Gu: except for the fact that he was considered as a genius when young because he remembered modern age poems, the fact that he is from another world doesn't change anything.
Lang Huan Library: I actually forgot at some point that he came from another world.
Douluo Dalu: same thing, I forgot. The isekai part plays a small part, but very small
X - Epoch of the Dragon: like master of Gu, the fact that he returns in time is more important than the isekai part.
Jiang Ye; Spirit sword Mountain and some others even skip the isekai part of the novel in the manga adaptation. (Or you learn of it very late)
...
75% of chinese isekai, the isekai can be erased without much of a change.
