First of all, Saber, I am holding back my dissatisfaction.
After the Holy Grail War, the Thirteenth Night of the Holy Grail coincided with the Mid-Autumn Festival. While people were sleeping, heroic spirits from all eras were summoned to the world by the remaining ten magicians, and they were all selected to participate in this magic night. The magician who wins the night of membrane magic will have a chance to make a wish to the "Five-Ren Mooncake", and the heroic spirit summoned by him will regain his freedom and be officially resurrected... However, due to an unforeseen accident, the duration of the thirteenth membrane magic night will be extended indefinitely until the appearance of the Wu-Ren Mooncake... People in this world will know nothing. For them, it is just a sleep, nothing more.
Sorry for the scumbag work from a newbie＠(￣-￣)＠
