Do you think the world has already been mapped? Xiang Nan thought the same thing until he discovered the absurd note left by his father - the end of Antarctica is not the ocean, but a wall of ice that cuts off the world. Outside the wall is actually the prehistoric world recorded in the "Book of Mountains and Seas": giant towering trees, heroic moves with human faces and deer bodies, mirage dragons breathing illusory mist... These are not legends, but a real secret realm!
Following Xiang Nan's footsteps, he will hold the guidebook left behind by his father, cross the ice wall barrier, and step into this bizarre world. However, dangers and opportunities coexist: the "spiritual energy" in the air can actually help people practice and build foundations, and ancient beasts contain rare treasures. The truth behind the disappearance of grandfather, the secrets carried by the family, and even the ancient contract between humans and gods are all hidden at the end of this world...
From science to fantasy, from exploration to immortality, the journey south has just begun - beyond the ice wall, is it destruction or eternal life?
