Stealing the Campus Belle's Gum, the System Praises Me as a Demonic Cultivation Genius

The school beauty, the object of every boy's unrequited affection, has just put a piece of gum in her mouth. The next second, I pluck it right out. The whole class falls silent. The school beauty is stunned. A voice appears in my mind: “Demonic Saint! Well done! This is the ultimate method for stealing an immortal maiden's opportunities!” I stare at the countdown to the college entrance exam, completely dumbfounded. Am I losing my mind? Later, I breathe in the school beauty's scent, and the System erupts: [Successfully collected an immortal maiden's vital essence. Reward: Banner of Ten Thousand Souls!] The school beauty turns red with anger, and the System sets off fireworks: [Excellent! The essence of the demonic path lies in unsettling her Dao heart and seizing her fortune! The Saint is getting the hang of it!] Holding the almost-complete Banner of Ten Thousand Souls, with demonic energy billowing around me, I stare at the panel, where more and more sinister cultivation arts are appearing, and sink into thought. It's all real. My name is Lin Jiang... I'm about to become a great demon!!!
