How Can I Have Any Taoist Companions?

Wu Youqing got a system But this system is not serious "The host needs to form a Taoist couple with the designated heroine in each of the seven reincarnations." "Okay^O^" "But after forming a Taoist couple in each life, the heroine must transform into a black man and kill her husband to become a Taoist." "..." "The mission failed?" "Erase the host." Wu Youqing just showed off and said it didn't matter. "Erase the host and everyone you hold dear." "It doesn't matter, I will take action."
