YU insists to fight for YIN. YIN tries to stop her and JIT finds it suspicious. JIT tells LING that YIN used to work in the brothel and he believes that there is something else had happened. They thus carry out investigation on YIN’s customers but they discover nothing. Later, they are inspired by a holy turtle and they discover something important. JIT goes to Qufu to carry out investigation on the new Magistrate TSUI CHONG-MAN. LING sees through his heart from his handwriting. He tries to test him by sending him a drawing with the word “heart” on it and he has new discovery. They therefore return to Jinan to question YIN. YIN requests them to stop disturbing MAN before she reveals everything to them and they agree reluctantly. CHUNG suddenly comes to arrest PAK for he wants to investigate YIN’s case again. In order to save PAK, POON tries to seek PONG’s help by sending him a famous painting.
