I Transmigrated into a Book and Turned My Whole Family into Villains

Jiang Baiyue watches as his entire family turns into villains and is stunned. I haven't even made a move yet! How did you all learn to be villains? My eldest brother is a guardian war god? He's clearly the God of Slaughter of the Jiang family, killing enemies, armies, and emperors. My second brother is a lovesick fool? He's obviously a ruthless killer who has severed all ties to love and leads the Jiang family's assassin organization. My third brother is a martial arts fanatic? He's clearly a top strategist who governs the country and manages its affairs. My fourth brother is a playboy who spends all his time chasing women? No, no, no. He's the director of the Jiang family's intelligence bureau. Jiang Baiyue stares at his four older brothers, dumbfounded... If that's the case, then as the fifth son, I can go ahead and squander the family fortune without a care, right? Little does he know that his brothers can all hear his thoughts...
