The Dating Sim Heroine Only Wants to Cultivate Immortality

[You are the heroine of the game. No matter how treacherous the secret realm or dangerous the situation, you always make it out unharmed. Your master cherishes you, your junior brother respects you, and your disciples admire you.] Lu Feng: ...Sounds nice. What about everyone else? [To live up to the heroine's destined-to-be-great status, they'll return to nothingness after giving everything for you. But you won't be lonely. New chosen ones will gather around you. You are the protagonist of the world and deserve the very best.] Lu Feng: ... Lu Feng drew her blade and stabbed the thing calling itself a System until it was a bloody mess. After physically destroying the System's consciousness, Lu Feng discovered she had gained a page called the Game Forum. There, she found information the System had hidden: 1. The male lead and the male supporting characters represent the happy and bad endings, respectively. 2. The popularity of the game characters determines who gets assigned the lead and supporting roles. 3. Her old-fashioned master, her vice-monitor junior brother, the child everyone else's parents wished they had as a disciple... Every one of them had an unbelievably smooth life, nothing like the miserable backstory typical of a male lead! While worrying about how to save her master and friends from their future, Lu Feng accidentally uploaded a selfie to the forum. In the photo, the corners of her eyes were red, her hair slightly disheveled, and her sharp gaze concealed a murderous intent. The blood from the people she'd cut down not long ago hadn't yet dried. She looked wild and violent. Half an hour later, the post titled "The Stunning, Battle-Worn Heroine" had risen to the top of the trending list, and the old fossils of the cultivation world had stepped into a new world. In short, if she wanted her master and friends to become beautiful, powerful, and tragic, then she, the pride of their sect, would have to betray it first and become a Demon Lord! Surely, as the most evil people in the Nine Provinces, each of her friends would be tragic enough! Theme: Many emotions matter more than a single, exclusive love.
