The next day.
Dudian came to the tailor shop to receive robe and mask. He put on the clothes and it just fit him. Afterwards he went to the street alley where the hidden chamber was. Suddenly he smelled two people inside, one less person than yesterday.
"Sure enough, there is someone here every day." Dudian secretly thought. As he got into the alley he wore the mask and went towards the wall which was covering the entrance. His hand touched the fabric that was covering the wall. If ordinary people accidentally were aware of the fabric and tore it off they would still see a wall. But Dudian knew that it was entrance to the chamber as a glance was enough for him to see the gaps between the bricks.
Dudian picked up a stone and knocked it lightly.
There was no response.
Dudian once again gently tapped twice.
