Lin Mu hid behind a wall and peeked out from the edge. He then saw the guard pull out a small metal contraption from his sleeves. Lin Mu could not see the contraption clearly except for the glint of light it reflected.
Lin Mu walked around the wall and used the alleyways to get close to the guard. The guard was pointing the contraption towards the townsmen and stalking behind them. The townsmen were completely unaware of the guard following behind them and were just conversing amongst themselves.
The townsmen soon reached the residential district and entered their houses. The guard saw this and waited for thirty minutes before leaving. Lin Mu took a breath of relief and went back to follow the guard.
