Demonic Cultivator? I'm a Righteous Disciple of a Prestigious Sect!

(Light ensemble cast + no romance) She is Tang Zhiyi, a quick transmigration traveler, and she failed her mission. At the moment of death, darkness swallowed her vision, and she said goodbye to this worldline. ...Or did she? When she opened her eyes again, she had actually entered this world in person. Even worse, her beloved System, Yijiu, had broken down. She cried, threw a fit, and rolled around on the floor. In the end, her father sent her to a sect. She was willing to go, if only she hadn’t been a demonic cultivator in her previous life. The testing stone detected the demonic energy from her past life. Ahhh! Luckily, no one could tell what this mass of energy was. But she was as good as dead, because the testing elder had summoned the sect master. She prepared to accept her death, but the sect master made an exception and took her on as his personal disciple. Tang Zhiyi was bewildered, and her senior brothers and sisters didn’t understand either. When they asked the sect master, he said, “The eldest senior sister was in the same situation as you back then.” What eldest senior sister? The second senior brother, third senior brother, and fourth senior sister chimed in unison: “The eldest senior sister was incredibly powerful.” Tang Zhiyi asked, “So, is the eldest senior sister in seclusion now?” Everyone fell silent. The eldest senior sister had sacrificed herself for the Dao! Tang Zhiyi looked grief-stricken, but inside she had already planned her escape. Come on, weren’t they just trying to find a stand-in for their unattainable dream girl? What personal disciple of the sect? Not even a dog would Yijiu: [Cultivation can help me repair myself.] Fine! She’d be the sect’s personal disciple! “Yijiu, look up He Qiuyu for me.” [bm?90a*@GluZyBp%cyBSRUF*#M] “What the heck?” […Invalid target query.] Tang Zhiyi narrowed her eyes. There was something about her eldest senior sister that wasn’t quite right.
