Episode 20 recap: Ma Long found his father's diary.

Ma Long and Ba Dou were unwilling to give up. Tai Bao revealed that the rumored twelve golden dragons were the keys to unlocking the treasure chest of the kingdom. Inside the treasure chest was the route map to Huang Chao's treasure. It was rumored that the treasure chest ended up in the hands of the descendants of the Wanderer's Army. Ma Long found it strange because he himself was a descendant of the Wanderer's Army. Tai Bao pointed out that if Ma Long had the treasure, wouldn't he have already found it long ago? Ma Long was at a loss for words, and Ba Dou grew anxious. Their grandfather had been missing for many years. Tai Bao calmly mentioned that their grandfather had a habit of keeping a diary and suggested that they go home and search for it. Upon hearing this, Ma Long instantly had an idea and rushed home.

On the other side, Zeng Xiao Gong and Sun Zhengyi had just arrived at their temporary residence. Zeng Xiao Gong took out the six golden dragons from his father and combined them with the six golden dragons they currently had. They successfully opened the treasure chest, and inside, there was indeed a map. Just at that moment, someone unexpectedly appeared! However, accompanying that person was Xuan Ju, and the familiar Mu Lao Shi was also there—he was Xuan Ju! Despite Sun Zhengyi threatening to burn the map, they still couldn't gain the upper hand.

Ma Long opened a dusty box and inside, he indeed found his father's diary. Everything was explained in the diary, and Ma Long immediately called for Ba Dou to start working. Under the pressure from Xuan Ju, they followed the map and began searching for the treasure!
