Hogwarts: Bloodline And Oathstar

Traveling through the HP generation, Lin Yanqing was bound to a system that could only send out emojis to be cute, and was forced to lock a soul contract with Bat King Snape. When the black magic organization came after them with an evil mirror that could reflect the soul, the two sworn enemies had to run naked and dance together under each other's magic power...

When all the lines of fate suddenly intersected, they discovered that the contract that started as a conspiracy had already become the most terrifying taboo in the magic world...
