What is the first episode of treasure hunt in an ancient house haunted by bears?

At first, I explained the theme. During the period of War of Resistance against Japanese Aggression, a group of people with lofty ideals kept a batch of the most precious national treasures in secret places in order to protect cultural relics. After the war, some of these national treasures are still missing.

At first, it was in the hospital. Doudou is at Dad's bedside. His father had something to say, and then gave Doudou a key. Doudou wanted to finish what his father had not finished, so he took the key and wanted to go to the ancient house to find the national treasure himself. When he left the room,

Dad Doudou said: "Golden scales turn into dragons, and the four gods watch the fire. After leaving the hospital, Ma Gelin followed silently.

Then Doudou came to the fork in the road, and Xiong Qiang came. As a result, they also knew about it.

Well ... bears, bears can talk ... (similar to Lin Zhao's reaction in those days), and then Logger Vick is bragging about developing scenic spots.

Qiang first called Doudou's children children children, and later renamed them children. Then Doudou didn't want them to know the secret of the national treasure and pointed them in the wrong direction, although Xiong Qiang finally arrived.
