Here is the English translation of your Chinese text:
The night was deep and quiet.
Prince Jin sat alone in his room.
A shadowy figure pushed open the door.
Prince Jin glanced at the shadow cast on the floor and said irritably, "You've taken so long, I thought you had died up in the mountains."
The man wore a straw hat and a mask, with a black cape that almost blended into the night.
He entered the room and sent a palm strike to close the door, then walked over and sat opposite Prince Jin.
With a faint smile, the man said, "I've been here for a while, but Prince Jin was busy seeing the doctor. I thought it best not to disturb."
At the mention of this, Prince Jin's expression stiffened.
The man noticed the awkwardness in Prince Jin's demeanor and chuckled. "Did His Highness fail?"
Prince Jin naturally refused to admit he'd been played by Lu Yuan, who had used pig's blood and the hair of a brothel servant.
