Liang Qin transmigrated with an FGO Servant Summoning Pool and wished to the Black Grail for the world to be destroyed.
The Black Grail exploded on the spot, splashing black mud everywhere. Countless men and women emerged from it, calling themselves "players." They could possess Heroic Spirits and cause all kinds of trouble.
That alone would have been bad enough.
But why are they from a new world where human civilization has been wiped out, and why are they so curious about human civilization when they know almost nothing about it?
What, they're even trying to learn human history from the Heroic Spirits?!
