ALL THE ANSWERS THEY NEED

SHEN JI YUN quickly moved towards the courtyard.  He used two of his Temporary Skills – [Conceal] and [Accelerate].  Increasing his speed while hiding his presence.  Arriving at the courtyard, he immediately checked every room as fast and as stealthy as he could.  

As he continued to move towards a certain direction of the courtyard, the number of servants got less and less.  A clear sign that he's going in the right direction.  Then he heard a crashing sound.  Like the sound of breaking glasses.  Having confirmed that he's definitely on the right track, he rushed forward where the crashing sound came from.  And he ended up in front of a room, quite isolated from the rest.
