If there really is a time-travel bureau, then it cannot have only a few members.
Travelers are not the protagonists. The butterfly effect they trigger will affect different worlds and the indigenous people.
These are the work logs of different travellers, as well as the stories of different indigenous people who were affected by the butterfly effect brought by the travellers.
If you feel that the writing style of different stories suddenly changes when you are practicing writing, it is basically the author's intention.
Collection of short stories.
1. There is a male protagonist (danmei) and a female protagonist (romance).
2. Various animations have nothing to do with each other.
3. Short story collections are all kinds of short stories.
4. For specific settings, see Chapter 18 of "Wanxiang Wuji" in the column, or Chapter 8 of "Paradise"
