I woke up—naked, next to an equally naked college girl—and we'd been transported to another world!

What the story is about

After falling through a strange light on Changbai Mountain, unemployed mountain guide Su Datang and college student Lin Jing awaken naked in a prehistoric wilderness. Using his outdoor skills and knowledge of hunting, tools, and construction, Datang helps a tribe of women survive and gradually builds a settlement while they search for answers about the strange world.
