Gu Chaoyan and Sword One exchanged a look. Both of them had heard the sound of soft footsteps. Sword One was a well-trained hidden guard from Shadow Door so she was able to sense the movement and Gu Chaoyan had an even sharper sense of hearing, since she was very strictly trained in her previous life. Also, she had been drinking magical water since she arrived in this world, so she was very aware of everything around her.
Sword One took out her sword, when she sensed something strange going on outside. She decided to take a look outside the room, since her mission was to protect her Elder Miss, and she needed to shield her in whichever situation.
Qing, who had not been aware of anything, did not know the situation for the moment, but when she saw the look on her Elder Miss and Sword One's faces, she understood that something was wrong. Instead of speaking loudly, she said nothing and continued to take care of Gu Chaoyan like before.
