In the beginning, the Sword Fairy didn't feel anything different but along with the passage of time she found her body feeling more and more weird.
At first, she only felt that her body was getting too hot for some reason, but other than it being a little uncomfortable due to the sweat she didn't feel anything else.
But later on, this heat that she was feeling started making her face blush and even turned her breathing hard and heavy.
This was when the Sword Fairy suddenly realized that even when she wanted to stop hugging Bai Long, her body just wasn't willing to do so.
It looked like her body had a mind of its own and didn't want to let go of the sexy woman it was hugging.
