The System Forced Me to Become a Playboy and Exchange My Bad Habits for Sainthood.

Traveling through the last years of the dynasty, Gu Bufan became the only child of the Gu family, the largest family in Linyuan City. Others were seeking immortality, fighting for power, and working hard to improve their cultivation, but he did the opposite. He hung out in wine shops every day, drank and dreamed, engraved eating, drinking, and having fun into his bones, and lived his life as a top-notch dude known throughout the city. Everyone was waiting to see the joke. The heir to the Gu family was rotten to the core, and the Gu family would be defeated by him sooner or later. But no one knew that Gu Bufan had already awakened to the strange system - the more outrageous the bad habits, the richer the rewards. "Ding~ Successfully exchanged for 'Eat, Drink, and Have Fun', cultivation level +10!" "Ding~ Successfully exchanged for 'Indulgence', cultivation level +100!" "Ding~ The exchange for 'Mengde's Ambition' was successful, congratulations on getting the mysterious technique!" Pretentious as the wind, arrogant to the limit; addicted to seeking death, but always able to survive in desperate situations; bullying the weak, persimmons pick on the weak. When Gu Bufan relied on "liver bad habits" to reach the Martial Saint level, the whole world exploded. Thousands of people looked at that dandy figure, and their hearts were collectively broken: "Why?! A waste full of bad habits can actually become a martial saint? It's unfair!" "What the hell is a Martial Saint?"
