In the distant lands of the East, humans and animals once coexisted in harmony. However, this peace was shattered when a mysterious magic arrow struck the ear of the favored minister Gao Qiu, granting him the ability to understand animal speech while losing comprehension of human language. Exploiting this, Gao Qiu sowed discord between animals and humans, turning them into enemies and leading to the persecution of mankind. Fortunately, a righteous force known as the "Liangshan Army," led by its commander Song Jiang (later revealed to be a monkey in disguise!), emerged to combat this threat. The most formidable group that strikes fear and gives headaches to Gao Qiu is the "First Army Assault Squad," a five-member team consisting of Lin Chong, Sun Erniang, Lei Heng, Dai Zong, and the rabbit Tiao Tiao. To restore peace between animals and humans, the First Squad engages in a long and intense series of game-like battles against the animal army!
