Why Does the Male Lead Keep Turning Evil?

As a villain who transmigrated into a book, Chi Li understands her role perfectly. She does her best to stay away from Yue Jiuyang and Lin Yuening, and never gets in the way of the male and female leads. So why is the male lead still out to get her? She sparred with her senior brother, and Yue Jiuyang injured him with a sword. She went down the mountain with her second senior brother to gain experience, and Yue Jiuyang made him drink a thousand-day brew. He never woke up. The only one left was her third senior brother, trembling in a corner with his arms around his sword scabbard. He looked away from Yue Jiuyang's dark expression and stammered, "Junior sister, I... I really don't have time!" Chi Li glanced at Yue Jiuyang, who had been scowling the entire time, and her eyes involuntarily trembled. "Then... I can only ask Martial Uncle Wei to accompany me into the secret realm." Yue Jiuyang: "Don't you dare!" P.S. The cultivation stages are divided into four major realms: Refining Essence into Qi (Spiritual Illumination, Opening Light, Integration), Refining Qi into Spirit (Heart Movement, Spiritual Stillness, Golden Core), Refining Spirit to Return to Emptiness (Nascent Soul, Leaving the Body, Spirit Division), and Refining Emptiness to Unite with the Dao (Integration, Tribulation Transcendence, Great Ascension).
