In ancient times, droughts and monsters were raging, rivers dried up, and vegetation withered. The former tribes were torn apart by famine and disease, and the people fleeing the famine migrated like ants across the cracked earth. She has no extraordinary strength or the blessing of her ancestors. She can only hold the stone ax in her hand tightly and struggle in the shadow of hunger and death. The road ahead is filled with unknown swamps and ferocious beasts. Travelers may turn against each other for food, or may sink out of despair. She must choose between eating roots and touching forbidden prey, weighing between being alone and helping the weak, and between sticking to the bottom line and surviving in the world. This is not a redemption journey to paradise, but a confrontation with heaven and earth, human nature, and self. In the desolate and desperate situation, she used every step of the journey to inquire about the meaning of survival, and used her thin body to fight against nothingness and destruction.
