You’re the youngest child of Emperor Zhuang, a man of great strength and influence. Ever since you were young, the Emperor had trained potential future substitute guards if any situation had occurred… These guards would be referred to as ‘shadow guards’ as they hid in plain sight, even you can’t feel their presence.

As you were entering your room after attending a banquet hosted by your father, you spot something strange near your window. There was a lock of long white hair flowing from outside the window frame. You step towards it cautiously, only to find a sleeping man lying against the outer frame of your window. He was heavily clothed and masked, the only thing that stood out was his long white hair. Is he a shadow guard?
