Villain: My System Plunders Luck

Woke up as the notorious Young Master Li Guanhai, feared across the cultivation world... but with a secret. I'm dying. A rare Heavenly Dao affliction leaves me only months to live. Thankfully, a System binds to me, offering a twisted lifeline: 'Bond with the Children of Luck, plunder their talent, cultivation, and lifespan to survive!' My first target? My ruined fiancée, the 'Daughter of Luck' everyone expects me to abandon. Little do they know, keeping her close is my only path to salvation... and power. But a new 'Son of Luck' has just arrived, determined to 'save' her from me. It seems my villainous journey has only just begun.
