The idea comes from the synthesis after reading two novels called "Making Trouble". I pay tribute to both of them, but I will never plagiarize! ! !
The general setting is that FGO mobile game players take the system to travel through time, Chaldea is in a different space, and Young Flash is thrown out of the system as a poster boy.
Preliminary setting of three summon expansion modes
1. Mo Yili's dream summoning (change clothes, gain part of the abilities of the heroic spirit, 50% of the power)
2. Possession summoning of the heroic spirit to possess oneself (will be affected by the heroic spirit's character, the subjective consciousness still belongs to the protagonist, power 70%)
3. 10-Minute limited battle call (heroic spirits have autonomous consciousness, power 100%)
