Yu Qingxian accidentally discovered a mysterious national travel map. In order to complete the check-in task on the map, he formed an exploration team and embarked on a journey full of surprises. They traveled through green wetland parks, climbed up mist-shrouded mountain planks, and visited quaint small town streets. Along the way, they met friendly villagers, learned to identify plants, observe nature, and recorded every beautiful scene with a brush.
