Transmigrating into a Cultivation World full of crises, Shi Nian just wants to lie flat and survive until she dies of old age.However...Why do the fellow disciples around her all seem a bit off?The aloof senior sister is a vicious supporting female character, and in the end, her own partner extracts her soul and peels her bones just to save a mortal woman.The gentle second senior brother is a tragic character; his childhood sweetheart fiancée claims she and a poor boy are true love, and eventually, that poor boy breaks in and cripples second senior brother's cultivation.The cold third senior brother is obsessed with swordsmanship and has eyes only for that, but the female lead clings to him obsessively, saying she loves only him. The male lead is jealous because of this, and third senior brother is schemed against and dies pierced by thousands of arrows.The kind junior sister saves a tiger demon, who professes admiration for her, but in the blink of an eye, throws her into the Abyss for the sake of the female lead, causing her to fall into demonhood, ultimately dying tragically under the Righteous sword.Shi Nian is shocked to realize she has transmigrated into four books at once.And all her fellow disciples are the villains in the books...When a group of protagonists righteously come knocking on the door.Shi Nian, who has been lying flat all this time, suddenly realizes.Huh?When did she become invincible?
