How Is My Drunkard Senior Brother So Broken?

Gu Changge has a problem. He’s transmigrated into a Xianxia world as a mediocre senior disciple destined to be a stepping stone for the rising "Junior Protagonists." His talent? Average. His future? Death. That is, until he realizes his system is… different. [Every sip of wine increases comprehension.] [Every jar of alcohol boosts cultivation base.] While other disciples spend decades in freezing caves, Gu Changge is in his courtyard, getting absolutely wasted. The harder he drinks, the stronger he gets. The Sect’s Reaction: "Look at him... our once-great Senior Brother is broken. He’s drinking himself to death over a heartbreak!" The Senior Sister: "I never meant to hurt him this much..." Gu Changge: (Wakes up with a hangover and a new Immortal-grade technique) "Wait, who is the Senior Sister again?" What to expect: Hardcore Progression disguised as laziness. Misunderstanding Comedy (The world thinks he's tragic; he's just leveling up). Zero Romance/Harem drama (The MC only loves his wine). A "Broken" System that makes every drink a breakthrough.
