Anything goes: quick transmigration, infinite flow, creator, traveler, whatever, as long as it explores multiple worlds. I like seeing the protagonist experience different world settings. Ideally, the worlds should be unusual and original, not based on existing settings. They can be from any era or culture.
The trilogy of the "Two Worlds and Three Lives" series: One Life (campus growth) + Two Lives (science fiction) + Three Lives (a collection of modern urban love stories), with novel themes and multi-line linkage! 🍇🥭🍉🍓🥝🍒👍👍🍒🥭🥝
