At first, when she reached the accommodation of the disciples of the Blood Skull sect, she noticed that something was off about the light and behavior of everyone. These anomalies were because of the illusion formation.
If she had discovered that she was in an illusion then, things would have turned out different. But she eventually ignored these inconsistencies and went along with her crime.
This sealed her fate and ensured that the patriarch of the Purple Flower sect couldn't save her. So she will live the rest of her days in agony.
The two nascent soul cultivators didn't tell anyone about what happened that night. The news that they told people was that Purple Vine had entered seclusion in order to break through to the fifth mortal coil.
The people of the Purple Flower sect were excited to hear this. They also hoped dearly that she would succeed in her attempt and they would have two nascent soul patriarchs.
