I started writing this long novel in 2014, and it has various personal settings.
In order to make a commemorative book overhaul this year, it includes [A Hundred Years Ago], [Modern Times], [FGO Interaction Chapter], [Possible Crossover Heroine Chapter], [Zhenni Extra Chapter] and [Possible Future Chapter].
The overhaul and update time is uncertain, and it is expected to go along with the [Future Chapter] which is kept updated next door. If you are interested, you can check out the unmodified ones left before, so I won't post them here.
Intention: I just want to fill the hole
