A Record of a Mortal's Journey to Immortality: I Become Invincible by Eavesdropping on Secrets

[Feel-good power fantasy, mortal cultivation, ensemble cast, delusions of grandeur, ruthless decisiveness] When Wei Lan accidentally overhears a secret belonging to someone from the Demon Sect, he discovers that secrets are the quickest blades for killing enemies. One day, Wei Lan looks toward the Empress. "Your Majesty, you wouldn't want the whole realm learning the secrets of your bedroom, would you?" "Please, don't! Tell me what I must do to keep them secret." "I want to seek a path, the one you've been hiding all along." The Empress lowers her head. The mighty ruler of the realm has no secrets at all before Wei Lan. "Very well, but I need the Empress Dowager's consent." Wei Lan shakes his head. "No need. I went to the Empress Dowager first, and she couldn't keep her path hidden either."
