A sharp laugh came from the corridor. Even if one did not see them, they could feel their old aura.
Gu Man took a step out of the door. Just as she took a step, she could feel the cold air outside the door sweeping over. She seemed to be waving casually behind her, but she had actually set up a spiritual door at the door, blocking all the cold air from entering the room.
She looked at the empty corridor and looked around unintentionally, but her gaze was actually wandering somewhere.
That was where the spiritual energy was the most abundant.
A silver line gradually spread out from Gu Man's pocket and quickly spread forward along the ground. When it touched the place with the most spiritual power, it stopped.
In just a second, the end of the silver line gradually expanded at an extremely fast speed until it exploded.
