He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.

Sixteen years after transmigrating into the world of cultivation, Lu Yi’s long-lost cheat finally awakened. The cheat was a simple task panel where one could earn various rewards by accepting and completing tasks. Lu Yi was surprised to find that he could publish tasks for himself and complete them for rewards. So Lu Yi embarked on the path of self-publishing tasks for himself. He published a task for himself to “practice the Divine Sword technique ten times,” and upon completion, his level in the Divine Sword technique increased by one. He published a task for himself to “defeat an outer disciple,” and upon completion, he obtained a precious Perfect Qi Condensation Pill. He published a task for himself to “break through to the Foundation Establishment Realm,” and upon completion, he obtained a top-grade magical weapon. Without realizing it, Lu Yi found that even becoming a saint or ancestor seemed easy with this system.

Su Yi has played many vicious female supporting roles such as a mistress, a witch, a villainess, and what not, earning the title “national bad woman.” receiving quite a few haters.

She then fell in love with a veteran who had NO. IMPERFECTIONS. AT. ALL! (Su Yi said in all seriousness). It was just that he wasn’t quite pleased with her reputation….

Therefore Su Yi ran back to the company, crying. “I want to change my public image! I don’t want to be a villainess anymore! I want to play a white lotus flower, it’d be great if I could be the wife of a soldier who would sacrifice everything for love!”

Even so there was one thing Su Yi was certain about right from the start.

Chu Ying was hers, no objections allowed!
