Episode 4 recap: Xiaoyu decided to stay at the pawn shop.

The little fish that was rescued that day found Wandering Pawnshop. As soon as he entered, he saw Da Dou and immediately wanted to thank Ma Long for saving him that day. However, Da Dou's smiling face instantly turned sour when he heard his name and he corrected the little fish, saying that his name was Da Dou and not Ma Long. The person who came out that day was the same Da Dou standing in front of her now, not Ma Long. Da Dou then asked the little fish to put down what she had in her hands, claiming it was a bomb to scare her.

Soon after, Ma Long and Zeng Xiao Gong came out, still in their disguises. Ma Long was only wrapped in a towel. The little fish became anxious and directly questioned Ma Long about the woman next to him, asking if she was Ma Long's partner. After receiving a negative answer, the little fish finally relaxed. Ma Long immediately scolded Da Dou, and Zeng Xiao Gong, feeling the awkward atmosphere, went back inside. Ma Long himself didn't know what to do. The little fish then expressed her intention to stay at the pawn shop to help. Both Da Dou and Ma Long strongly resisted, with Da Dou stating that he was still struggling to make ends meet. However, the little fish didn't mind at all and became very clingy. Ma Long quickly took the opportunity to escape back to his room.

In the exhibition hall of the Tang Dynasty artifacts at the Archaeological Museum, a strange man appeared. After looking around, he approached a woman and struck up a conversation. He first offered to help take photos and then revealed that he was a thief who had found a partner. The two exchanged a knowing glance and left the hall together. In the evening, the security guard patrolling the exhibition hall heard some strange sounds. Then, to his surprise, the exhibits started moving, and the security guard was frightened and fainted.
