Episode 19 recap: Ma Long and Ba Dou uncover Zeng Xiao Gong's true identity.

Ma Long and Ba Dou were analyzing the dead ants on the ground, questioning how the ants could accurately locate the Golden Dragon. Observing the ants circling on the ground, Ma Long fell into deep thought. Soon, he made a discovery and stated that ants can secrete a pheromone, and as long as the leading ant knows the scent of the Golden Dragon, the following ants become the carriers. That's why when the leading ant dies, the ants behind it also die in circles. Therefore, if the leading ant can identify the scent of the Golden Dragon, it can lead the way. Afterward, Ma Long and Ba Dou prepared to head to the museum.

Zeng Xiao Gong quickly received Ma Long's message and became flustered. He couldn't find happiness despite the news. Ma Long and Ba Dou were the first to arrive at the museum and began reviewing the surveillance footage. To their surprise, they discovered that Zeng Xiao Gong had manipulated the gloves that touched the Golden Dragon near the safe. Ba Dou went crazy upon seeing the evidence, although he was reluctant to believe it, the truth was right in front of him.

Ma Long called Zeng Xiao Gong to ask where he was at the moment, and Zeng Xiao Gong admitted that he had lost himself. However, Ma Long assured him that he could be found. Meanwhile, Zeng Xiao Gong was already sitting in Sun Zhengyi's car. It turned out that Zeng Xiao Gong had fallen in love with Ma Long long ago! Ma Long and Ba Dou later found the person who introduced Zeng Xiao Gong, and that person stated that Zeng Xiao Gong didn't seem like someone from the Xuanju organization. The Jiangshan Treasure Box and the Golden Dragon are related to the legendary Huang Chao's treasure!
