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.

If I can't win no matter what I do, then I'll crush those so-called heroes at their very roots. - Quality Fan Translations, Made by Fans for the Fans - Villain Takes Over The Academy
