I'm a Magician, Yet I'm the Second Generation of a Cultivator

"I'm finally graduated, damn it." Tang Qi, the Clocktower's worst student and a repeat senior, declared.

"What? Sis, you're a cultivator? My little sister is a cultivator too? My parents are cultivators as well?"

A lighthearted comedy with rigorous worldbuilding and intelligent villains, though the protagonist might not be so smart.
