The story wasn't actually very convoluted.
When Feng Qing'er and Qing Tan entered the ancient temple, they arrived in the same long corridor as Damien did, along with everyone else. And just like him, they had walked pretty far before they chose a door to enter.
The demons and the rest of the participants had also split up and entered the various doors in the corridor. As for their fate? Perhaps nobody knew besides the one controlling those maidservants.
When the two girls entered the room they chose, they were immediately stunned into a stupor. There were two paintings on the wall in front of them, and no matter how hard they tried to look away, they found it impossible.
It was as if their souls were being sucked into the painting.
