Episode 7 recap: There is a new discovery in the museum's surveillance footage.

After returning to the pawnshop, Zeng Xiao Gong quickly drew a portrait of the person who plays the xun, based on the description from the old man. Ba Dou couldn't help but marvel at Zeng Xiao Gong's skills and said he could set up a street stall with his talent. Shortly after, Zeng Xiao Gong was about to leave, but Ma Long offered to see her off and was rejected. Xiao Yu tried to persuade Ma Long to accompany Zeng Xiao Gong, but was also rejected. When Ba Dou offered to accompany Xiao Yu, he too was turned down. Ba Dou exclaimed, "Whether it's dry or flooded, it's all a dead end."

Zeng Xiao Gong left the pawnshop and went directly to the designated location specified by Sun Zhengyi, where she retrieved the missing golden dragon from the museum. The next day, after searching all night, Ba Dou had a new lead and was about to tell Ma Long when Xiao Yu interrupted. So, they had to discuss it over breakfast. Ba Dou discovered that the yellow powder was actually zombie powder, a kind of sorcery that originated from Africa. As for the yellow flower, it was the September Phoenix. When Ma Long heard this, everything became clear and had a reasonable explanation.

Zeng Xiao Gong went to see Uncle San with the golden dragon. As soon as she entered, she asked Uncle San why he wasn't taking his medicine properly. Uncle San replied that the medicine was useless. Then Zeng Xiao Gong showed him the golden dragon and said that now Uncle San could live to be a hundred. Unexpectedly, after taking a careful look at the golden dragon, Uncle San claimed that it was fake. Zeng Xiao Gong couldn't understand how the golden dragon in the museum could be fake.

Ma Long received a call from Teacher Mu. It turned out that there was a new discovery in the surveillance footage. The footage showed that the golden dragon actually moved on its own.
