noiselessly
In complete silence
Noiselessly means without making a sound.
The word describes movement or action that produces no audible disturbance: She noiselessly closed the door behind her.
It often suggests deliberate stealth or careful quietness, though it can also describe things that are simply silent by nature: The cat moved noiselessly across the room.
