Wielding Thunder, Shattering the Ninth Heaven

I had barely inherited a fortune worth tens of billions when I transmigrated into Qingyun Sect's lowest-ranking servant! I planned to save up spirit stones and keep my head down, but who knew I'd have a Chaos Thunder Mark between my brows, with talismans that come with a built-in buff? I tear through the servants' tournament... I went to the back mountain to deal with evil spirits, but didn't find any... Instead, I brought home a fierce, sharp-tongued female evil spirit. Now I feed her Yin Thunder like candy and keep her as my personal bodyguard... I thought I'd be following a steady cultivation story... But I fought my way from the mortal realm to the Nine Heavens, suffered more hardship than I can count, and filled half a book with grudges! Only at the end did I realize something was off about this path to immortality... If you're going to transmigrate me, at least do it right! Why bring me here!!
