Play trumpet in the world of horse racing girl

Traveled to the world of the horse racing girl, but with a system that I don't know if it was produced by Ayi's family, I have to keep gaining emotional points in this world!
So... isn't this system really produced by Ayi's family?What the hell is going on with these card pools?
Fortunately, the characters are pretty good, but the boss battle is very troublesome...
All in all, let's start from all corners, take the bread and cheese to the protagonists in the center, and run down in one breath!
Also-why haven't the authors who wrote about horse racing girls updated?As a reader, I have blossomed my own flowers, bastard!
