It tells the story of a young man, Amu, who has been dependent on an old shepherd since he was a child on the desolate border of the wilderness. There is only a mysterious dark green broken corner that has grown up with him as a link to the past. After the old shepherd passed away, he guarded a group of skinny sheep and a dilapidated earthen house, living a peaceful but difficult life.
A fall of an extraterrestrial stone broke the silence of Qiqiu, and the burning boulder smashed into the forbidden misty forest, attracting the fierce beasts in the forest to fight for it. And the truncated horn suddenly moved at this time, blending with a stream of red light, which not only gave Amu the ability to communicate with livestock, but also left a strange "shepherd's mark" on his palm.
In order to avoid the predators of the forest, Amu and his flock struggled to survive, and gradually discovered that the broken horn contained two intertwined powers - warm as life, hot as destruction, and even more faintly ancient and majestic. As he explored his own abilities, he realized that it might be related to the "shepherd" in the legend of Cangye who could communicate with all things and command all beasts.
The secret of the boulder, the origin of the broken horn, his own vague past, and the crisis hidden deep in the misty forest all pushed Amu out of the familiar abandoned hill. He will take the pastoral whip and the broken horn into the wider wild land, explore his own destiny amidst the disputes between major forces and the mist of ancient inheritance, and play a song of the Shepherd God about growth, courage and protection.
