I Meant to Join Wei, So How Did I End Up Restoring Han?

"The things I say might go unheard, but the stench of my farts? Everyone will catch it!" Lu Wan never asked for much—just a quiet paycheck in Cao Cao's Wei army after time-traveling to the late Eastern Han. But when the Cao forces drive him out, he decides to take a page from the legendary strategist Jia Xu: pull off a monumental stunt that makes him too valuable to ignore, then secure a cozy spot in the Wei bureaucracy. What could go wrong? Soon enough, Lu Wan realizes he's in over his head. Cao Cao vows to kill him. Liu Bei praises him as a savior of the Han dynasty. All he ever wanted was to kick back and do nothing.
