The Demon Sect Sent Me as an Undercover Agent, but the Immortal Sect Treated Me as a God.

The Demon Sect gave Lu Zhaozhao the last task: sneak into Taixuanzong and steal the Taiheng Initiation Heart under the sword-hiding platform. Before leaving, the three elders repeatedly warned - you must enter the inner sect, but you must not show your talent; you must gain the trust of your fellow sects, but you must not have a heart-to-heart with anyone. Lu Zhaozhao studied carefully for three days and decided to take the seventeenth place in the exam. As a result, she was the first to find the exit on the way to ask for help. In the Valley of Trials, she saved the entire team without letting the wounded block their retreat, and was ranked first again. During the sword array assessment, she was afraid that the spirit-detecting sword would shine out with demonic aura, so she could only dodge them all without touching the ground - still ranked first. On the day when the overall ranking was announced, the boss of the Twelve Peaks came with a sword and rushed to accept her as his disciple. Lu Zhaozhao stood in the crowd, touching the pulse-sealing needle in his sleeve, and understood for the first time: The scariest thing about being the first in the exam is that not everyone knows her. All the big guys who can fly want to come down and see her in person. She originally wanted to quietly steal the initiation and take her brother away from the Demon Sect. But as the investigation deepened, she discovered that her false identity had been prepared twelve years ago, and the secret that Taixuanzong desperately guarded was actually related to her brother's illness and the battle between good and evil for a five-hundred-year-old spiritual vein. What's even more troublesome is that Wen Xingzhi, the chief of the Discipline Hall, has blocked her at the door. He closed her flawless identity document and asked calmly: "Junior Sister Lu, an ordinary cultivator, why is he so good at destroying corpses and eradicating traces?"
