Wei Le Fuhuo Anlian De Shizun Wo Bei Po Kai Le Hougong

Hua Yingying transmigrated into the body of a poor orphan girl. When her life was hanging by a thread, an immortal master descended from the heaven to save her from danger. So Hua Yingying teased and flattered her master day and night, until she finally melted the master's icy heart. As soon as her master could overcome her final tribulation, they can be together for mutual cultivation and other naughty things… But who could have imagined that the master would fail the tribulation and crumble into dust! Now in order to resurrect her master, Hua Yingying must search the seven mirror realms to find the seven shards of her master and make love with each of them! Hua Yingying clenches her fists in frustration, "I'm only forming a harem so I can save my master!"
