Who Stuffed All the Systems into My Magic Cards?

Li Xiang arrives in a magic card world and settles at the bottom of the Magic Tower. He has nothing left to strive for in life and just wants to look after his family’s little magic card shop. But then he is chosen by a down-and-out young lady at the top of the tower and forced into a breeding game. Each breeder randomly picks one person to raise. Only the last one standing survives. The young lady is so hard up that all she gives Li Xiang is a low-grade Sequence Awakening Card, then leaves him to fend for himself. Li Xiang awakens the System Sequence. Sequence: Sign-In. Sign in daily to randomly receive a reward. Sequence: Enhancement. You can spend soulfire to strengthen magic cards, boosting their abilities for everyone. Sequence: Fusion. You can fuse any two magic cards into a new one with a fresh trait.
