After Transmigrating Into a Book, I Became Dao Companions with My Archrival

[Slowly revising; plot details and chapter titles may be added or removed] 1. Ding Xiandi transmigrates into a bizarre cultivation novel and becomes the supporting woman who goes mad after loving the heroine without being loved in return. The original owner was born a beggar, had no talent, and belonged to the worst-ranked major sect, which had only three disciples. Everyone mocked someone like her for secretly loving the radiant heroine. She arrives the day after the heroine publicly rejects the original owner. Ding Xiandi: “I'm doomed! I need to find someone to marry first, or I'll eventually die from a plot-mandated death!” During a class on cultivation law at Tianji Academy, the instructor calls out a familiar name. Ding Xiandi looks over in shock. The person is none other than You Fuling, who has competed with her over everything since childhood: her sworn enemy, at least in theory. To everyone's astonishment, the bottom-ranked student, who had confessed her feelings to the first sect's senior sister just yesterday, proposes to the second senior sister of the second sect! Ding Xiandi: “I scored one point higher than you in mathematical analysis.” You Fuling: “Shut up. I'm still number one.” Ding Xiandi: “I need your help, fast!” 2. Ding Xiandi, the bottom-ranked sword cultivator at Tianji Academy, has become cultivation partners with You Fuling, a genius spell cultivator! Sword Cultivation Department: “A fickle traitor like her deserves to be struck dead by heavenly lightning!” Spell Cultivation Department: “What does our genius see in this penniless nobody?” Alchemy Department: “Nothing to do with us.” Music Department: “Is it traditional for major sects to marry off their second senior sister?!” 3. Ding Xiandi thought having a cultivation partner would save her from being forced onto the path of her destined plot. She didn't expect the drug to be administered anyway; the target had just changed. Ding Xiandi: “Wait here! I'll find an antidote!” You Fuling: “You will do just fine.” Ding Xiandi asked, “Do you regret it?” “Is there any point in being with a fellow transmigrator like me, a disposable extra?” In a damp, chilly cave, the woman whose fate could not be changed whether she transmigrated into a book or not answered firmly, “No regrets. It's worth it.” “If we both die, maybe we'll go home.” Ding Xiandi: “If you go back after killing someone, do you think you'll have a good life?” You Fuling: “Then you have to stay with me. Otherwise, I'll kill you too.” Ding Xiandi: “Did they get your character all wrong?!” Nobody told me You Fuling was this deranged! [Major spoiler] She is one of her bones.
