The soldiers in the special vanguard forces pretty much consisted of men.
Everyone knew Gu Yan stayed in the room alone. Hence, even if they really needed something from her, they would knock first.
More importantly, this would only occur during the day.
Bai Changle consistently followed such manners in the past few days.

'Who could it be at this hour?'
Gu Yan was usually vigilant.
She still recalled locking the door from the inside before.
This meant that even if someone had the keys, they wouldn't be able to enter from the outside.
'So… how did this person come in!?'
Thinking about this, Gu Yan slowly got up and grabbed the hook next to the cauldron. She took two steps towards the door. When she reached a safe distance, she asked calmly, "Who is it?"
The door was closed.
No one answered her.
There were a series of footprints on the ground.
